editorial
Dear Reader,
are always evolving. Companies such as Wärtsilä,
which has a history stretching back more than 170 years, have different
characters in different decades.
Our brand is an everyday tool for communicating with the wide variety
of people who we meet on a daily basis. It’s fascinating to sit back and
think for a moment of those thousands of Wärtsilä people who are in daily
contact with our customers – one of them might be you.
We have people to meet and hands to rely on. Every one of us
communicates by reflecting our company values. We also share passions
– for engines, for serving our customers, and for solutions. So it does not
matter how much the business has changed over those more than 170 years,
one key characteristic has remained – a passion for what we do. This is
something you have surely noted.
The magazine you are holding is the face of Wärtsilä for all our
stakeholders, a child of our brand evolution. Its proud parents are Marine
News and Energy News. Both of them and some of our local customer
magazines have given the best of their genes to this lively new creation.
We are now presenting our world through new eyes, full of excitement.
Making a magazine for you is a privilege. It is with pride and pleasure
that I write to you under the title of Twentyfour7. Through this magazine
we want to share our desire to make things work, now and tomorrow.
Twentyfour7. introduces a new generation of the Wärtsilä brand.
Our commitment and passion is to offer you the best possible experience
– both in our products and services and within these pages.

FOLLOW THE SONG
GIANTS OF THE SEAS, Humpback
Whales can be found in all the worlds’
oceans. They are divided into four groups:
North Pacific, South Pacific, North
Atlantic and South Atlantic. The current
global population of Humpback Whales is
estimated to be about 35,000.
MOST POPULATIONS follow regular
migration routes, spending the summer
months feeding in temperate and polar
zones as the colder waters are nutrientrich. In winter they migrate to warmer
tropical waters to breed and calve. As
newborn calves have no body fat for
insulation, the sub-arctic waters in both
the northern and southern hemispheres
are too cold for them.
NORTH PACIFIC HUMPBACKS have
three primary wintering grounds off the
coasts of Japan, Hawaii, and Mexico.
South Pacific Humpbacks follow the
coast of eastern Australia and spend
their winters east of Queensland in the
sheltered waters of the Great Barrier Reef.
globe
HUMPBACK WHALES have extremely
powerful tail muscles and tail fins. Some
whales have been observed to swim at
speeds exceeding 32 kilometres per hour.
It takes them just 30 days to reach Alaska
from Hawaii.
THE SONGS of the Humpback Whale
are a subject of intense study and
speculation. Their complex and highlystructured calls are repeated for hours.

First Wärtsilä power plant
in Azerbaijan inaugurated
Last spring, the Azerbaijan
electricity company Azer-Enerji
awarded Wärtsilä a contract for
five gas-fuelled power plants with
a combined electrical output of
450 MWe. The new plants will
serve as decentralized power
plants supplying the national
grid in five different regions in
Azerbaijan.
The first plant, Astara, was
inaugurated in February 2006
by President Ilham Aliyev of the
Republic of Azerbaijan, and is
due to start operating early in
2006. The other four plants are
scheduled for completion later in
the year. Astara is equipped with
ten 20-cylinder Wärtsilä 34SG
gas-engine generating sets and
has a total output of 90 MW.
Wärtsilä acquires company

BIOFUEL
Biofuels are a large source of
energy worldwide. They are
derived from forest, swamp
and agricultural biomass, and
from organic solid, liquid and
gaseous biowastes recoverable
from municipal, agricultural and
industrial processes.
APPOINTMENTS
COGENERATION
The simultaneous generation
of electricity and heat. Also
called Combined Heat and Power
(CHP). This method raises total
efficiency levels above 90% since
the heat produced during power
generation is recovered and used,
for example, in industrial processes
or to supply district heat.

accumulators inter-connected by
small-bore piping. The injection
pressure is adjusted as desired and
the injection timing (start and stop)
is controlled electronically. Wärtsilä
has used common-rail technology
to develop the “smokeless engine”,
which also reduces NOX and CO2
emissions.

HOW
ABOUT
A LITTLE
BUBBLY?
Champagne is for
celebration. It has launched
thousands of ships and
toasted billions of weddings,
inaugurations and business
deals. In more intimate
situations, it has witnessed
countless special shared
moments between couples.
Champagne has succeeded
perfectly in building a
consumer brand which
everyone desires. It’s an
excellent example of the
mysterious ways in which
we humans define ourselves
through what we consume,
and how we use food and
drink to give meaning to
social events.
The meaning and appeal of
champagne are universal.
So… when I tell you my
Saturday morning will
start with bubbles, don’t
you start to feel envious and
taste that unique thrill of
temptation?
Cheers!

New WLSA training

simulators to assist with practical
training. Already now, around 200
courses are scheduled to train nearly
2000 trainees from all over the world.

of its most interesting business
cycles ever. Order intake is at
an all-time high, freight rates
are high, the oil price is high
but at the same time the world
economy isn’t growing that fast.
The conclusion must be that
globalisation is also affecting
the marine industry and that
transportation by sea is growing
faster than world trade.
I want to highlight one
specific area which is of interest to Wärtsilä, namely the
cruise industry. Currently doing well, new and existing
consepts being developed mean that the cruice industry’s
prospects are even better. In percentage terms, the mostrapid growth is taking place in Europe and very much
with European passengers. Many new destinations such as
Dubrovnik and Libya are being added to ship itineraries.
The biggest growth in passenger numbers is of
course taking place in North America and in cruises
out of Florida with large ships featuring climbing
walls, ice-skating rinks, wine bars and large spas.
Another trend is that all cruise lines have an urgent
desire to become more environmentally sound - smoke
from a ship’s engines is very visible “pollution”, in a
form that both passengers and the public notice.
For an engine builder, engine efficiency is the main
road to environmental soundness. Wärtsilä has taken
this one step further by looking at the total propulsion
system, including propellers, seals, secondary-clearing
methods, lifetime support etc. This has given us
a very competitive solution with both the lowest
environmental burden and the lowest lifetime cost.
The next step when analyzing efficiency is to integrate
ship systems even further, and to be able to do this big
solution providers and strategic alliances between sub
suppliers and shipyards/shipowners are needed. Wärtsilä
will develop in the direction of a solution provider
while at the same time developing all the individual
components to be cost-competitive and best-in-class.

M/S SONG OF NORWAY
T E XT: J O H N A N D E RS I N
The “mother” of modern cruise ships
YESTERDAY M/S Song of Norway
was built by Wärtsilä Helsinki
Shipyard in 1969. Launched as
Newbuilding 392 from a slip berth
on 12 December 1968, she had
a capacity of 724 passengers
and was delivered to Royal
Caribbean Cruise Line on the 5
October 1970. Nowadays she sails
under the name Dream Princess
and is mostly cruising in the
Mediterranean for Caspi Cruises.
Her clipper-like bow and slim
lines make her a beautiful ship
and what was at that time a novel
and very high-class interior design
made her a favourite choice of
cruise passengers all over the
world. M/S Song of Norway has
inspired many naval architects and
ship owners in the development of
cruise ships, which are becoming
bigger and faster every year. There
will always be something beautiful,
perhaps nostalgic in the design of
her clipper bow which gives the
whole ship an appealing shape. Her
extension in Helsinki by some 26
metres (85 feet) in 1978 increased
the number of passengers she
could carry to 1196 and made her
look even better.
M/S Dream Princess has seven
Wärtsilä (Vaasa)-designed-andbuilt 624TS diesel generating
sets. At the time she was built
the Wärtsilä Helsinki Factory had
a foundry which cast the engine
blocks and cylinder heads for our
own design 24-type engines. Her
main engines are four Wärtsilä
Sulzer 9ZH40/48 built under
licence in Vaasa.

THE HELICOPTER RISES gently
and tilts forward like a dragonfly. The
rain-drenched asphalt shrinks away as
we ascend. The pilot straightens out
into horizontal flight and heads out from
Stavanger in southwest Norway towards
the open sea. Six men are riding in this
Super Puma helicopter. According to
the ILO, the UN’s labour organisation,
their workplace in the oil and gas fields
is the most dangerous job in the world.
Occupational safety legislation in Norway
has been framed to meet these risks, so
serious accidents are rare. These oilmen
have said goodbye to their families for the
next two weeks, which will be followed
by another four weeks vacation.
The orange survival suits they are wearing are made of thick rubber, as
required by safety legislation.
Relaxing guitar music is being played through the headphones, but
the sound is drowned out by the constant hum of the rotors. Two men
are reading newspapers, the others are sleeping.
NEW FINDS AT AN OLD DEPOSIT. After about an hour of vibrating flight, two
ships become visible on the horizon, one large and one small. The drilling
platform towers out of the sea.
The larger ship is the 214-metre Petrojarl Varg, designed for oil processing
and interim storage. The small but sturdy Norman Ranger ploughs through
the water around it 24 hours a day. It’s there to rescue members of the
Petrojarl Varg’s crew if they need to be evacuated, as rescue teams from
the mainland could never reach the ship in time.
As the helicopter begins its landing approach, its passengers pull up the
hoods of their survival suits.
Petrojarl Varg operates in the middle of the North Sea, a notorious
location for storms. This vessel, designed by a British company and built
in Singapore, is the flagship of Petroleum Geo-Services ASA (PGS),
a Norwegian company that specialises in oil exploration and production.
It has been producing oil at the Varg field since 1998. p
The twin-engined Super Puma

This deposit was declared exhausted at the beginning of the
new millennium and its pumping rights were available for almost
nothing. PGS purchased the majority of them and started threedimensional seismic measurements.
Several oil pockets previously inaccessible to drilling were found in
the Varg field. Double the amount of oil estimated was discovered,
and was then accessed using new horizontal drilling technology.
Many experts have designated the North Sea a twilight zone
in terms of oil drilling. They may have to reassess their opinion.
The greatest efforts in oil exploration are now however focused
elsewhere, in Arctic areas and in the South Atlantic. The seabed
off the coast of Brazil has been studied to a depth of 1,860 metres,
with promising results.
The helicopter curves towards the helicopter pad, where a
man dressed in a bright orange coat and white helmet guides its
descent. After its wheels touch the deck, the helicopter settles.
Passengers quickly exit onto the windy deck and make their way inside.
The changeover is carried out quickly, and the employees going
on vacation hurry into the helicopter.
IT’S A MAN’S WORLD. Petroljarl Varg is definitely a world of men.
The 40-person crew mainly consists of engineers, chemists,
technicians, mechanics, electricians and deckhands.
Petrojarl Varg is a double-hulled vessel with a capacity of
75,000 cubic metres, equivalent to 470,000 barrels of oil. At
early-2006 prices for sweet Brent crude oil from the North Sea,
the value of her cargo is well over USD 28 million.
“The unmanned drilling platform pumps oil to the vessel
from sediment layers located two and a half kilometres below
the seabed,” says Chief Engineer Jan-Erik Tenfjord. “Every two
weeks a tanker comes from the mainland to empty the vessel’s tanks.”
The ship only has one maritime
professional onboard. This is a sensible
solution as it does not move anywhere
but is held in place by ten massive
anchors.
If necessary, the vessel is turned
several times a day to minimize the
effect of wind and currents on the
pumping process. Control from the
bridge ensures that the 360-degree
rotatable turret engines move the ship
in the desired manner.

DEVIATIONS RECEIVE IMMEDIATE ATTENTION. Service Engineer
Kjartan Olsen guides us down the steep, narrow metal stairs of
his workplace. The noise coming from behind the fire doors in
the engine room is deafening.
The power generated by the massive marine gas/diesel engines
equals that of 400 family cars, i.e. 33,750 kilowatts or 45,260
horsepower. Kjartan Olsen is a passionate engine man who has
tended these machines for four years. The engines’ primary fuel
is natural gas, a by-product of the oil drilling process.
“They’ve never disappointed us,” shouts Olsen in an effort
to be heard through the ear protectors we’re wearing. He pours
some lubricant into the machine.
The engine room is tidy and everything is where it should
be. The standard pin-up
calendar is missing.
Kjarten Olsen grabs a rag
and starts wiping the side of
the engine with a firm hand.
“We always leave everything
in tip-top shape when the shift
changes.”
Life on this vessel is dictated
by routine, and the work is
handled around the clock in
two shifts. On the bridge, the
shift changes at 7 am, where all
important issues from meeting
production targets to possible
dangers on deck are discussed.
The vessel’s officers meet each
evening at 5.30 pm.
This morning things were a little less humorous than usual.
Members of the night shift explained that something was
wrong with the process: a few tenths of millilitres more oil than
normal was dripping into the water.
All deviations are recorded and dealt with promptly.
LOBSTER SOUP, MASSAGE AND MOVIES. In addition to a generous
salary and plenty of time off, the standard of living on board
also helps compensate for the extreme conditions. The tiny
cabins on the vessel are austere but functional. The most
important feature is a good bed, in which crew members can
sleep soundly before their next shift.
The ship’s kitchen is a long way from austere. The menu
includes delicacies such as filet steak and lobster soup. As the
work is so physically demanding, good food is essential, and
luxury hasn’t been overlooked. The dessert table offers five
different kinds of ice cream, a similar number of cakes and
puddings, whipped cream, berries and fruit – to say nothing of
the remarkable selection of chocolates on the coffee table.
The only thing that’s missing is cognac to go with the
coffee – and that’s only available on the mainland. This ship is
completely alcohol-free. There is a wild rumour that a glass of
wine might have been served with Christmas dinner.
“Gaining weight is a more serious health problem here,” says
Olsen, patting his generous waistline.

encouraged to do so. Every ten-minute session of exercise earns the
employee a stamp, and these can be collected and exchanged for a
gift certificate.
As well as working out, the crew can surf the Internet or watch
movies on the big screen in the onboard cinema.
There are plenty of leisure time activities on board. Kayaks, knives,
fly-fishing lures and oil paintings bursting with Rubens-like female
figures emerge from the workshop on the lower deck. The crew of this
production vessel can even put its own band together.
HIGH WAVES ARE A TESTING EXPERIENCE. Snow
is flying in the early
morning darkness. The temperature has dropped close to zero, and a
chill that landlubbers cannot comprehend cuts through to the bone.
Floodlights turn the snowy deck yellow as the dark-blue sea gently surges.
A cargo vessel nuzzles up to the Petrojarl Varg bringing diesel fuel,
food and drinking water from the mainland. On its return trip it takes
a few containers of machine parts, dishes and carefully-sorted waste.
Loading is a tricky business. If the container hanging from the
Petrojarl Varg’s crane were to strike any part of the cargo ship, the
results could be disastrous.
Waves of 20 metres are a regular feature of the North
Sea, and they sometimes reach 30 metres. The really bad
weather is legendary.
“The wind speed was about 40 metres per second
when the wave hit. Those panes of glass up there just
shattered,” says Chief Engineer Jan-Erik Tenfjord,
pointing at a row of windows near the ship’s bow. The
windows are some 20 metres above the ship’s waterline.
“Water poured in and took everything from the cabin
corridor along with it, including the television.”
FISHING IN THE BACKYARD. Fortunately, there are also
quieter days.
“On really beautiful summer evenings we set up
a barbecue on deck seven and enjoy our time off in
t-shirts,” says Olsen.
“If the sea is really calm and the captain gives
permission, we lower one of the lifeboats and go fishing!”
Many different fish inhabit the waters around the
ships. A surprisingly-large number of species from coral
to dolphins have been found on the floor of the North
Sea as a result of oil exploration activity. Underwater
microphones dating back to the days of the cold war have also recorded
lively communication between whales.
Oil companies that use high-powered echo sounders for exploration are
regulated by legislation designed to protect life in the world’s oceans. If they
don’t observe such regulations, the powerful signals from these devices can
be very harmful to ocean mammals.
When it’s time to change crews the men who are leaving are as excited as
children on Christmas Eve. Many of them still have a long trip home after
the helicopter has taken them to Stavanger.
Members of the Petrojarl Varg’s crew live in places such as Spain,
Thailand and the Philippines. But when you have a break of four weeks,
there’s plenty of time for a trip home that may last half a day.
For years, experts have predicted that oil will run out in the next few
decades. New exploration technologies mean that offshore workers may well
be kept busy for much longer.
If oil drilling expands to Arctic regions, Jan-Erik Tenfjord, Kjartan Olsen
and other professionals will have to don an extra pair of longjohns beneath
their orange overalls!
A world of its own surrounded by hundreds of miles of sea, jobs on Petrojarl Varg are
in high demand. Hundreds of applications are usually received for each vacancy.

Since the technology already exists, moving
from fossil fuels to biofuels is not difficult.
Fuel availability is the primary concern.

[ F E AT U R E ]
In 2001, the UK’s Custom and Excise formed a special unit in Wales.
The objective was to track down and penalise any drivers using biofuels,
such as vegetable oil, to run their diesel engines. Sniffing out unusuallyfragrant exhaust fumes, highway patrols have collared several dozen offenders
who are saving more than 40 pence a litre by diverting oil from the kitchen
cupboard to their diesel engines.
In South Wales, an ASDA supermarket in Llanelli has slapped a ration on
sales of cooking oil after astonished internal auditors found that it was selling
far more than any other outlet in the country. The Customs and Excise unit
quickly acquired a nickname: ”The Frying Squad”, and while this is a good
reflection of British humour, it’s even better as a reflection of the rapidlychanging landscape in fuel supply and regulatory control.
The world’s known oil resources have traditionally been considered
sufficient to cover consumption for approximately 40 years. Recent trends,
however, indicate that it is becoming difficult to find new oil sources that
will cover the massive current increase in oil consumption. At the same time,
locations in which oil can be found are increasingly difficult to access.
Recent rises and fluctuations in oil prices, although mainly influenced
by global politics and a lack of refinery capacity, have clearly highlighted p

Olive oil company becomes major energy supplier
Casa Olearia Italiana, an olive oil
company located in Italy, now

liquid biofuel. Wärtsilä has installed
three Wärtsilä 18V32 units with
a total output of 24MWe. “Small

Development Engineer, Power Plant
Technology, “Our experience with
liquid biofuel engines is encouraging.
In several European countries, the
use of biofuel receives credits which
make a biofuel operation viable and
ensure profitability. Companies
moving in this direction will see a
return on their investment in a very
short time.”
According to Ari Suominen, General
Manager, Environment, Power Plant
Technology, combining the highlyefficient diesel combustion process
with clean liquid biofuel ensures low
emissions of CO2, CO, particles and
hydrocarbons without secondaryemission control systems. “The
power generation facility in Casa
Olearia Italiana also uses a selective
catalytic reduction (SCR) system
to achieve a 90% reduction in NOx
emissions. From an environmental
viewpoint, it’s a very sound
proposition.”

the vulnerability of an oil-dependent society. This has
led to a situation where alternative fuel solutions, such as
emulsified fuels, natural gas and liquid biofuels, are increasing
in importance. At the same time, efforts to slow or at least
mitigate climate change means that regulations governing
emissions multiply.
Companies are thus seeking to maximise energy efficiency,
minimise overall emissions and secure the future of their plant
investments. In short, they are looking for flexibility. Flexibility
in the fuels they are using, in the emissions they create, and room
for manoeuvre in the face of an uncertain and rapidly-changing
energy landscape, both in terms of supply and regulation. There
have already been some interesting developments.
In the oil and gas industry, for example, operators
increasingly want to use associated gas to power their
installations. Associated gas was previously a waste product on
oil rigs, burnt off by flaring. There are now power plants that
use this associated gas to supply operational energy to rigs and
oilfields. This increases the efficiency and economy of each rig
and reduces emissions.
Similarly, in the Liquified Natural Gas (LNG) shipping
sector, operators and shipowners are replacing steam boilerdriven turbines with LNG dual-fuel, electricity-generating
power plants, a choice which results in a massive increase in the
efficiency and flexibility of their plant. Flexibility is the key.
“In the 1990s, medium-speed diesel engines usually used
heavy fuel oil (HFO) for power generation applications. Diesel
engines, with their high simple-cycle efficiency, were the ideal
solution for utilising HFO, a byproduct of the oil-refinery
process,” says Vesa Riihimäki, Vice President, Power Plant
Technology in Wärtsilä’s Power Plants business. “But in recent
years we have seen a rapid and specific increase in applications
employing natural gas. We can utilize our long experience in
building lean-burn reciprocating gas engines and offer our
customers state-of-the-art solutions.”
Fuel comes from a range of sources. Not only are there
the various grades, such as natural gas, light fuel oil and
different grades of heavy fuel oil, the number of alternatives is
increasing. “Lurking just over the horizon are biofuels, a very
interesting new market,” says Riihimäki. Biofuels are typically
vegetable oils produced from soy beans, rapeseed and palm oil,
among other sources.
“Palm oil is one of the best. Currently, the largest sources of
palm oil are in Malaysia and Indonesia, but I’m just waiting
for the day that Brazil starts to produce liquid biofuel in large
quantities for export,” says Riihimäki. “The availability of
a fuel is the key. Once security of supply is guaranteed, the
market will begin to take off.”
“The great advantage of palm oil is that it is carbon neutral,”
he says. “CO2 is released to the atmosphere during the
combustion process, but will be absorbed back as the oil palms
grow, hence the CO2 will be recycled. As palm oil fuel is used,
new crops will use the CO2 that results from its combustion.”
More importantly, this evolution from fossil fuel to biofuel
is relatively easy to negotiate, as the UK’s “Frying Squad” p
32 Twentyfour7. 1.06
A classic example
of fuel flexibility
Batamindo Industrial Park in
Indonesia is a classic example of
fuel flexibility. Four Wärtsilä 18V32
engines were installed in 1993 and
another 15 have subsequently been
added. After the Sumatra–Singapore
pipeline came into operation, natural
gas became available on the island
of Batam and Batamindo sought to
access this new supply of fuel in the
most cost-effective way. Wärtsilä has
therefore started to convert 12 of the
park’s engines from heavy fuel oil to
natural gas.
DF a natural choice for natural gas
feature
Liquified Natural Gas (LNG) carriers
represent a huge opportunity for dual-fuel
(DF) engines and have become popular with
shipowners and operators for their efficiency,
flexibility and low environmental impact.
“Currently there are four dual-fuel-electric
LNG carriers under construction and another
eighteen on order,” says Barend Thijssen,
Sales Director, Wärtsilä Ship Power Solutions.
“The demand for LNG shipping capacity is
expected to double in the next ten years,
so this is a growth market.”
Traditionally, gas evaporating from a vessel’s
LNG tanks is fed to boilers that drive a
steam turbine. “It’s inefficient, and the gas
coming from the LNG tanks is not sufficient.
Substantial amounts of heavy fuel oil (HFO)
have to be used to supplement the gas,”
says Thijssen. Switching from steam boilers
and turbines to DF engines improves plant
efficiency from 29% to approximately 43%.
Using less additional fuel, either the costly
and relatively clean marine diesel oil (MDO)
or the cheaper but less clean HFO, yields
lower operating costs and lower emissions.
As the ship has to carry less additional fuel,
more cargo space is available, and the overall
efficiency of the operation is higher.
Currently, Wärtsilä is the only company
able to supply dual-fuel engines that are
large enough to power LNG carriers. “We
are a leading player in this growing market,
but that fact hasn’t gone unnoticed by our
competitors,” says Thijssen.
LNG carriers are a natural market for dualfuel engines, where they are becoming the
engine of choice. But owners and operators of
floating oil- and gas-production installations
are also interested. As regulatory control over
a range of emissions such as nitrogen oxides
(NOX), sulphur oxides (SOX) and carbon
dioxide (CO2) increase, LNG will certainly
enjoy increased popularity as a marine fuel
in many more applications.

feature
discovered. “The technology to run on liquid biofuel exists,
and conversion from using HFO to liquid biofuel is relatively
straightforward. The primary concern is securing availability
of the fuel. Today, liquid biofuels are expensive, but we can
see that in certain regulatory environments, they are a clear
winner,” says Riihimäki.
Even for those firms that commit to one form of energy
supply, HFO for example, it’s not difficult to switch to
another type of supply, for example liquid biofuel. According
to Riihimäki, the conclusion is clear: “Businesses need fuel
flexibility, the ability to switch quickly from one source to
another, to ensure the security of their supply, to protect the
integrity of their investment, and also to adapt to the changing
regulatory environment.”
That said, the regulatory environment is currently skewed,
since it looks at the concentration of individual emissions that
result from combusting a fuel, such as nitrogen oxides (NOX),
sulphuric oxides (SOX) and carbon dioxide (CO2), instead of
looking at the impact of the fuel as a whole.
GARY HOULDER/CORBIS/SKOY
“It’s a well known fact that reciprocating diesel engines
have very high simple-cycle efficiency, which results in
low greenhouse-gas emissions. At the same time, the high
combustion temperatures create NOX emissions” says
Riihimäki. “We feel that regulators should look at technologies
as a whole. Different technologies have different characteristics,
and the emission limits set should therefore recognize the
characteristic benefits as well as the drawbacks. Having said
that, we recognize the need to improve the technology. We
are constantly working on improving efficiency and reducing
emissions”.
And this isn’t the only issue that regulators have to face.
According to Ari Suominen, General Manager, Environment,
Power Plant Technology, emissions control is a balancing act
involving the best available technology, cost, efficiency and
impact. “A new technology may reduce emissions, but lowering
emissions means that costs rise,” he says. This is an issue
regulators need to recognize. Business leaders, meanwhile, need
to look at all the options – and keep them open.

In projections of energy consumption, one
of the most important drivers is growth in
economic activity. Over the medium term (20052010), it is assumed that GDP will grow at an
annual rate of 3.1%. The expected growth in
key energy-intensive industries is also a critical
element in these forecasts. Strong growth in both
the iron and steel and basic nonferrous metals
sectors is expected over the medium term.
ELECTRICITY GENERATION BY FUEL
In terms of the fuels used, we anticipate that
growth in electricity production will be led by
natural gas, followed by renewables and black
coal. Growth in the use of brown coal and diesel
will be lower.
Abundant reserves of natural gas in our region
have resulted in several state governments

LESSONS FROM RECENT BLACKOUTS
The recent blackouts have shown that while
electricity reform creates more dynamic system
operating conditions, rules and operating
practices have changed to only a minor extent,
and a comprehensive, integrated policy response
is therefore required to avoid blackouts reaching
unacceptable levels.
This augurs well for Wärtsilä’s large and
efficient natural-gas-powered intermediate and
baseload plants.
IN CLOSING
For many years Wärtsilä has been promoting the
benefits of medium-speed gas engines in the
Australian market. High efficiency in high ambient
temperatures, minimal water usage in the world’s
most arid continent, and the availability of
multiple plant configurations all mean an exciting
future for the Wärtsilä 34 gas range.
The increace in fuel prices means that
customers are looking more closely at
efficiencies. The excellent efficiency of Wärtsilä’s
products gives the company a strengthening
competitive edge while oil prices are high.

Kaisa Ojainmaa is equity analyst
at SEB Enskilda in Helsinki.
In the
industrialized
nations, the
deregulation of
power markets
has driven
investment in
smaller-sized
power plants
with shorter
pay-back
times.
Wärtsilä caters for the world’s
growing power needs
World electricity demand is growing. Increasing
prosperity, globalization and population growth
create a steady two per cent annual growth in
use of electricity around the world. Most of this
growth comes from emerging economies of Asia,
Middle East, Africa and Latin America, where
rising standards of living create urgent needs
for new generating capacity to run factories
and newly-purchased home appliances for airconditioning, cooking, heating, and refrigeration
equipment. As infrastructures are underdeveloped, large coal or nuclear power plants
cannot be added without major grid investments.
Engines therefore often turn out to be the
preferred technology for power generation in
emerging economies. The competitiveness of
Wärtsilä’s diesel engines in power generation also
comes from the rapid delivery, even to the most
remote sites.
In the industrialized nations, the deregulation
of power markets has driven investment in
smaller-sized power plants with shorter payback times. Also, oil-fired plants are increasingly
being replaced by natural gas-fired plants which
have become more competitive with the start of
emission trading in the EU. The environmental
benefits and efficiency of natural gas are expected
to make it a favoured choice for new electricity
generation capacity in coming decades. Wärtsilä
has recently experienced significant growth in gas
power plant orders and these currently represent
close to half of Power Plants’ total order intake.
Decentralized power production is often the
most sensible solution, which is why the market
potential for Wärtsilä will continue to exist for
years to come.
Global mix of vessel orders lifts demand for
Wärtsilä’s medium-speed engines
The shipbuilding industry enjoyed another strong
year in 2005. After three record years for new
vessel orders, shipyards will be the busiest they
have ever been. As shipyards are currently running
at full capacity and have long delivery dates,
some reduction in vessel orders is natural. Last
summer appears to have marked a peak in new
orders for tankers and bulkers, whereas project
activity remains robust in sectors important
to Wärtsilä: cruise ships, RORO vessels, LNG
carriers and offshore applications, driven by
the booming cruise and energy markets. A reorientation of orders away from the bulk shipping
market towards the container and specialized
sectors means that Wärtsilä is a clear beneficiary
of the current trends in end markets. Also, lack
of capacity in Asia has shifted orders to European
shipyards, particularly those for small and
specialized vessels. One result is that Wärtsilä has
gathered a strong backlog of orders, with deliveries
extending through to 2008 and beyond.
Service sales provide a cushion
for cyclical ups and downs
Engine sales in the Ship Power and Power Plants
markets are highly cyclical, and the exact timing of
peaks and troughs is really anybody’s guess. On the
other hand, Wärtsilä’s increasing share in Service
sales provides a cushion against these cyclical ups
and downs. Compared to just 30 per cent five
years ago, service business now accounts for more
than 40 per cent of total sales by the Group’s
Power Businesses.
Fuel shares in world electricity generation, 2002-2025
100
% of world electricity generation
2005 was a wild year. Wärtsilä shares rose by 58
per cent, on top of which total dividend yield
amounted to more than four per cent. Activity in
the global shipbuilding market was robust while
high fuel prices also kept investment activity
lively in the power sector. Wärtsilä’s net sales and
profitability continued to improve, with earnings
growth no longer being solely a result of reduced
costs. Currently, strong demand in end markets is
driving growth.

A record-breaking year
A U T H O R : J O S É P H I N E R A M S AY, I R M A N A G E R
2005 was our best year ever in many respects.
Net sales by the Group’s Power Businesses climbed
to EUR 2,520.3 million (2,224.7 million), an
increase of 13.3% compared to 2004. Operating
income in Power Businesses totalled EUR 202.5
million and, as planned, reached the profitability
target (EBITA) of 8.0%. Order book at the end of
the year was at record level: EUR 2,905.7 million,
up by 56.6% compared to 2004.
Ship Power – success in many sectors
2005 was an outstanding year for our Ship Power
business. The number of orders received was a
record and totalled EUR 1,545.3 million, 84.7%
up on 2004. Net sales increased to EUR 710.3
million (631.2 million), an increase of 12.5%.
Growth in our LNG-carrier segment continued,
and major orders included 24 Wärtsilä 50DF
engines for AP Møller-Mærsk A/S and Kawasaki
Kisen Kaisha carriers. The offshore sector was
active throughout the year and we received several
significant orders for equipment to be installed
on oil platforms and support vessels. Sales of total
Ship Power solutions rose strongly during the year.
A good example was the order for 32 engines and
16 thrusters from the Danish company AP MøllerMærsk A/S for an oil-drilling platform.
Services – growth through acquisitions
Strong growth continued in the Group’s Services
business. Net sales were 16.7% higher than in the
previous year at EUR 1,093.1 million. We acquired
the German company DEUTZ AG’s installed
base of engines (totalling 12,500 MW), and thus
became the worldwide supplier of original spare
parts and services – including technical support –
for DEUTZ medium-speed marine engines. We
also signed our first Global Maintenance & Support
Customer Agreement for ocean-going vessels with
Reederei Blue Star GmbH in Hamburg, Germany.
This agreement covers a substantial part of the
maintenance and operational support for a number
of ships in the Blue Star fleet and is an excellent
match for the specific requirements of vessels that
trade globally in a liner service.
Power Plants – a stronger foothold
in gas power plant markets
Order intake for our Power Plants business
was high during 2005 and particularly good in
the second half of the year. During the fourth
quarter, order intake totalled EUR 346.6 million,
an increase of 63.7% on the same period in
2004. New orders received during 2005 totalled
EUR 865.2 million (1,019.5 million). In 2004,
Wärtsilä received orders of exceptional size from
Iraq. We further strengthened our position as a
significant supplier of gas power plants during the
year, a good example being the order for five power
plants received from Azerbaijan.
Good growth outlook going forward
Demand in the ship power and energy markets
looks likely to remain favourable for Wärtsilä for
at least the first half of the current year. Based
on the strong order book, Wärtsilä’s net sales are
expected to grow this year by as much as 20%.
The profitability level of 8% reached in 2005 will
remain. Net sales are expected to show further
growth in 2007.

America’s growing need
38 Twentyfour7. 1.06
Few people would
associate country
singer Willie
Nelson with energy
production, but
that’s exactly what
he is doing. Nelson,
72, has birthed
his own brand of
alternative fuel,
BioWillie, which
he hopes will help
American farmers
– BioWillie biodiesel
can be made from a
number of crops –
and thus reduce the
need for foreign oil.
While
BioWillie may never become popular, it’s just one of the recent
suggestions for solving the problem of the growing American demand for energy.
The US was able to keep the production and consumption of energy in balance
until the 1950s, but over the years, energy use has outpaced domestic production.
In 2004, about 29% of total US energy consumption consisted of imported
energy – and that share is expected to grow. The country’s energy consumption
is estimated to increase at an average rate of more than one per cent per year, and
domestic production is likely to have a hard time keeping up, the US Department
of Energy says.
One of the biggest challenges in meeting the growing demand is the ever
increasing disconnection between what Americans want – affordable and
environmentally-friendly energy – and how they want to get it, says Jim Owen,
Director of Media Relations at the Edison Electric Institute. In order to provide
more energy, power companies need to build new plants and lines, but many
people don’t like this.
“At the same time as the public’s environmental concerns are understandably
becoming more dominant, we need new sources of energy because the population
is growing and we are consuming more energy,” he says. “No one wants to live
next to a power plant, but somehow everyone expects to get affordable energy.”
Although US energy production takes many forms, fossil fuels exceed all
other sources, accounting for 80% of total energy production. Coal is the most
important, making up 32% of total energy production, followed by natural gas
(28%) and oil (20%). Nuclear power, which constitutes about 12%, and renewable
energy sources (9%) such as biomass, hydropower, geothermal energy, wind and
solar energy make up the rest. p

WILLIE NELSON STORY IN BRIEF
in-depth
THE WAY IN
WHICH THE
US HANDLES
ITS ENERGY
BUSINESS
MATTERS
TO THE REST
OF THE WORLD.
Coal may lead production, but Americans, who spend the equivalent
of more than EUR 423,000 million each year on energy, consume more
oil and gas than coal, nuclear power or renewable energy.
The country’s industrial and manufacturing sector uses about onethird of total energy consumption, while transportation uses some 27%,
residential 22%, and commercial 18%.
The appetite for imported energy is driven by petroleum
consumption – a fact that is hardly surprising to anyone who has
driven on the interstates or even just looked at the map and noted the
country’s true size. Since 1994, the US has imported more petroleum
than it produces. Today, half of all the oil consumed is imported.
The use of natural gas has also outpaced production. Currently, Texas,
Louisiana and Oklahoma account for more than half of all the natural
gas produced in the US, but more than 15% of total consumption is
made up by imports, which come in the main from Canada. Most of
the natural gas is used for heating homes.
Energy supply and demand play a crucial role in national security
as well as in economic output. The military and economic strength of
the United States mean that the way in which the country handles its
energy business also matters to the rest of the world.
To be able to supply residents, motorists, businesses and factories
with sufficient energy, the US can try to increase its own production
from either existing or new sources. It could also choose to import more
energy or try to clamp down on consumption – or do all three.
Some proposals for the first alternative include opening up the Arctic
National Wildlife Refuge in Alaska to oil drilling – an attempt the US
Senate recently blocked – and trying to resolve barriers to building new
nuclear power facilities after a hiatus of more than two decades.
A third suggestion is the federal government’s USD 1,200 million
Hydrogen Fuel Initiative, which is intended to reduce the country’s
growing dependence on foreign oil by developing technology for clean
hydrogen production and hydrogen-powered fuel cells. The government
believes that hydrogen technology has the potential to save 11 million
barrels of oil per day – about the same amount as daily net oil imports.
Based on public comments by President George W. Bush, the current
administration is interested in making the country less, not more,
dependent on foreign sources of energy. Increasing imports does not
appear to be high on the president’s agenda, even though that’s what
may have to happen .
As far as consuming less energy goes, the administration mentions
developing products that give consumers the same and even better
performance at lower cost by using less energy. As well as making
homes more energy efficient, the administration wants to do the
same for vehicles, and mentions hybrid cars, which are powered by
a combination of gasoline and electricity, as an alternative already
available to drivers.
People like Willie Nelson are not waiting to see when – and if – the
new initiatives materialize, they say they want action now – even if it
does mean driving a car that smells like peanuts.

Wärtsilä power plants
Wärtsilä is one of the beneficiaries of deregulation in
the US utility industry. The company’s Power Plants
business sells dispersed generation power plants
which can help large utility companies handle swings
in energy demand. They can also provide municipal
utilities and industrial customers with reliable and
affordable energy systems.
Wärtsilä sells 50–250 MW decentralized power
plants that use either natural gas or liquid fuel – in
some cases both – to municipal utilities, industrial
customers and large utility companies. A typical 200
MW plant costs USD 130–160 million and can operate
for more than six or seven decades, says Frank
Donnelly, Vice President, Power Plants, Wärtsilä
North America, and adds that most plants are
replaced not because they are worn out, but because
new technology offers more efficient solutions.
Power plants supplied by Wärtsilä are often
called dispersed generation plants, shaping plants,
or extended-peaking plants. Their characteristics
include fast start-up times – less than ten minutes
– and variable loading as well as good efficiency,
says Donnelly. They are used mainly for electricity
generation, though some also produce heat.
According to Donnelly, municipal utilities such
as the City of Rensselaer in Indiana buy Wärtsilä’s
plants for two main reasons: reliability and cost. Many
towns still purchase power from privately-held utility
companies, but they also have the option to use their
own plant. Sometimes it is cheaper for a municipal
utility to generate its own power than to buy it.
The same applies to many industrial companies
such as Canada-based Barrick Goldstrike Mines,
which selected Wärtsilä to supply a gas power plant
for its operations near Reno in Nevada (see “Leanburn simple-cycle strikes Nevada gold” on page
51). Manufacturing, mining, and other industrial
companies who have their own power plants can
purchase power from a large utility company when it is cheap, and
generate their own energy when prices are high.
Utility companies are also buying Wärtsilä’s plants. As they have
to deal with demand that goes up and down like a rollercoaster,
they use smaller, fast-starting plants to provide so-called ‘shaping’
power, says Donnelly.
When demand for energy suddenly rises – for example in the
morning when the majority of the population are getting up –
utility companies need extra muscle. The same applies when an
energy source such as a wind turbine stops operating, or when
one of the company’s plants breaks down.
“Our plants basically help large utility companies cope with
swings in demand,” Donnelly says, adding that such plants are
often classified as ancillary services.
“If a utility company suddenly loses the output of a plant, it has to
replace that capacity quickly or the whole system can come down.”
Before deregulation, which started some 14 years ago, large
utility companies didn’t have to worry very much about swings
in demand. They had plenty of excess power-generation capacity
and brought it on line when they needed to – and charged their
customers for it. Now that plants operate in a competitive market,
42 Twentyfour7. 1.06
TRICIA MEADOWS/GLOBE PHOTOS/SKOY
ARE SHAPING THE US ENERGY LANDSCAPE
no one wants to have excessive capacity because doing so is
expensive.
“Our plants can help their systems when they need help,” says
Donnelly, who has worked for Wärtsilä for 18 years. “They could
be considered a product of deregulation.”
Generating peaking power and ancillary services by using the
plants that Wärtsilä supplies is significantly less expensive than
having a large coal-fired installation that is not fully employed.
According to Jussi Heikkinen, Marketing Director in Wärtsilä’s
Power Plants business, the company’s products are also more
economical than the competition.
Although Wärtsilä has been successful in the US, it faces some
challenges, says Heikkinen. Major competitors in the US are
domestic gas turbines, and Americans are not necessarily familiar
with Wärtsilä technology. Most of the competing gas turbines
have been developed from aircraft turbines, while Wärtsilä
technology is based on reciprocating engines, says Heikkinen.
“Seeing is believing, though,” he says. “We have had people
visit Colorado or Nevada, for example, to look at our power
plants, and when they come back, they admit to being pretty
impressed.”
in-depth
Almost everyone who lives in the northeastern
United States and Canada is likely to remember
where they were on 14 August 2003. That’s
when a power blackout caused chaos at airports
and on roads, resulted in essential appliances
shutting down, and left millions of people without
either lights or air conditioning.
The outage – North America’s largest-ever –
affected some 50 million users in eight US states
and Ontario, Canada, and cost businesses an
estimated USD 13,000 million in lost production.
While some blackouts are difficult, if not
impossible, to prevent – those caused by
terrorists or natural disasters such as hurricanes
– poor practice, the lack of an entity that oversees
the whole of the North American electrical
system, and continuing delays in improvements
to transmission reliability have not helped.
After the 2003 outage, the Electric Power
Research Institute, a non-profit consortium of
utility companies, issued a plan for upgrading
regional power grids to make use of modern
information technology. The central element
of the plan is a “smart grid” that monitors
itself and takes corrective action as and when
required, reporting the occurrence of problems
immediately.
Digital control of the power grid would result in
an interactive power system that is merged with
a communications network to provide the realtime exchange of information and power. Energy
consumption decisions by businesses and
consumers could be made on the basis of real-time pricing
information. This initiative is now known as the “Intelligrid,”
and has an estimated implementation cost of USD 160,000
million over 20 years.
To guarantee improved electrical reliability, an Electric
Power Reliability Organization is being established which
will have statutory authority to enforce compliance with
reliability standards by different market participants. More
than 3100 electrical utilities operate in the US
The US Department of Energy’s Office of Electricity
Delivery & Energy Reliability (EDER) is also working on
energy storage, transmission reliability, and electricity
distribution transformation programs. One example of the
energy storage program is a USD 25 million power plant
in Mississippi that stores electricity generated during offpeak periods for use when the need for power increases.
According to EDER, this plant can provide power for 7500
homes for at least ten hours.
While power outages have been making headlines in
the past few years, the US Department of Energy also
acknowledges that a prolonged interruption in the supply
of basic energy – electrical, natural gas, or oil products –
would have a devastating effect on the nation.
Many people are not waiting for the government or utility
companies to act. Electricity generators, which can be
purchased for as little as USD 350, are becoming more
popular. ABI, a technology research firm, expects total
generator sales in the US to rise from USD 5,300 million in
2003 to USD 6,900 million by 2011.

High
on speed
JARI VALO has been
surrounded by model
planes all his life. He
seems to have a magical
touch. One of his earliest
memories is launching
a plane that no-one else
could fly. Now he’s
reaching out for world
records.
44 Twentyfour7. 1.06
AT THE AGE OF three, Jari Valo tagged along with his
father to the local aviation club in Helsinki. All the men
there were trying to fly a small, free-flying model plane, but
they just couldn’t. In the end, one of them gave the plane
to the kid who took hold of it, gave it a neat little twist and
then watched it fly higher and higher above his head.
“I don’t know what happened, but for some weird
reason, I managed to make it fly,” says Jari. Forty-three
years later, we’re in his home in a Helsinki suburb, about
five kilometres from that same club. “I have a very vivid
memory of the whole event,” he says with a smile.
This three-bedroom apartment has a certain style.
The vintage stereo, an antique clock, coffee-table books
about cars, the art on the kitchen wall, all contribute to
the feeling that nothing is here by chance. The room
closest to the front door has wings, engines, paints, tools
and rack upon rack of spare parts for the planes that hang
on the walls and sit in drawers. He calls it “The Lab”. It’s
the epicentre of Jari’s apartment. “I’m in there every day,
doing something.”
Trimming the untrimmable. Valo’s career as an
aeromodeller didn’t start at the age of three. It was his
father’s hobby, not his. It wasn’t until his teens, when one of
his friends started building planes – knowing very well that
Trimmed to the limit

Jari had access to some serious knowledge – that Jari took a shot at
it. And it was a very serious shot. By 19, he was already one of the
best in Europe. Today, he has twenty-plus – “21, 22, something
like that” – Finnish championships under his belt, and corresponds
with a vast network of air model experts around the world.
In the beginning, Jari got his hands on some Italian Rossi
engines that were pretty famous at that time. They were in fact
so good that according to some experts, there was no way to trim
them. What you had was what you got. But the engine’s creators,
brothers Ugo and Cesare Rossi, didn’t know Jari Valo. Improving
the unimprovable was a challenge he couldn’t resist. Soon, the
Rossi engine was spinning like never before.
“Once I succeeded in trimming their motors, there were no
boundaries for me. I jumped into this hobby, and I went in

that it probably wasn’t good for my grades at school.” p

passion
Parts from the sauna. As Valo now puts it, he
had more energy than knowledge. Trial and
error was his preferred method. As he wanted
to be the best, he was ready to do whatever
it took. And since it was the 1970s, and he
didn’t have any huge sponsorship deals, he
had to be smart.
“Once, I wanted to make wings out of
Abachi wood (African maple). It just happens
that sauna benches are made of Abachi. So I got
hold of some and made wings out of them.”
One of the classes in which he competes
is speed. In a competition, planes start on a
starting dock, a rack with wheels that support
the model before it takes off. The plane
travels in circles around the pilot, first on
the ground, taking off when it has picked up
sufficient velocity.
The first two rounds are for making sure
that the plane is travelling on its own, and not
being helped by the pilot yanking the control
lines. The next ten rounds are timed. Winning
speeds exceed 300 kilometres per hour.
“I built my first speed plane when I was 16.
A year or so later, I started experimenting with
single-blade propellers, and I realized that my
planes were just as fast with those with twoblade propellers. That gave me the potential to
build more-efficient planes and engines.”
Not everyone was happy with the young
Finnish innovator. “Some people were saying
that my planes were dangerous and that the
engines would blow up. Well, they didn’t, and,
single-blade propellers are now a standard
in the competition,” says Jari. “I guess it was
pretty tough for some of the others that this
young fellow just left them in the dust.”
means he has also outsourced some parts of
the construction process. “Between myself
and my girlfriend, Laura, who’s also an
aeromodeller, we use about 70 planes a year,
and since each one takes about twenty hours
to build, well, it all adds up”.
Backup from eastern Europe. Valo finished
fourth in the European Championships
in 1979. During the 80s and early 90s he
wasn’t particularly active in competitions,
but when the spark ignited and passion took
over again it was serious. Gone was the lone
ranger, and instead, he had an impressive
international network of engine builders and
other specialists, all of them either European
or world champions.
After the Berlin Wall came down, Jari got
access to enthusiasts in former Soviet states.
He located kindred spirits and established
close working relationships with two engine
constructors in eastern Europe who now
provide him with the top-quality engines that
he trims for competition.
The sheer volume of the planes he owns
A perfect burn. But the final goal of all
this activity is still to be achieved. He has
complete trust in his planes and is just about
to reach out for what he’s truly aiming at.
“I’ve had some really bad luck. Even though
I’ve won the world cup total competition,
I’ve often finished only fourth or fifth in the
world championships. A few years ago, I
clocked 311.9 kph in the unofficial practices.
After the competition, the official world
record stayed at 311.2 kph.”
It’s not all about competing. This passion
needs fuel. “A Swedish friend of mine once
said that the most beautiful sound he knew
was when his Nelson engine got up to 30,000
rpm. I know what he means. When my engine
gets to 43,000 rpm and the burning process is
perfect, it’s certainly music to my ears.”

The first-generation
GasPac device used
in testing is some six
metres long, just over
three metres high and
2.5 metres wide. It has
a thermal capacity of
6 MW. Units delivered
to customers are
always customised for
the engine power and
gas employed.
GasPac™ is
a Wärtsilä trademark.
GasPac gets more out of engines
Wärtsilä has developed technology that offers customers the high efficiency
and power of gas engines even when poor-quality natural gas containing heavy
hydrocarbon is being used. GasPac uses a catalyst to improve gas quality.
THE INNOVATION that improves gas quality
was discovered in the autumn of 2004 while
working on another Wärtsilä project developing
fuel-cell technology. After joining the fuel-cell
technology unit, Timo Mahlanen, Development
Manager, Fuel Cells, who had previously been
marketing Wärtsilä gas engines, realised that the
pre-reformer employed in the fuel cell could also
be effective when used in gas engines.
“Engine capacity has to be reduced when
poor-quality gas containing a lot of heavy
hydrocarbons is used,” says Mahlanen. “Since
customers quite naturally want to get the most
out of their engine, I began to work with Sören
Karlsson, who was developing gas systems
in Ship Power. We were working on a catalytic
process that could be used to improve gas
quality.” Their work led to an innovation that is
currently in the process of being patented. The
GasPac name has already received international
trademark approval, and registrations in
Finland and the European Union region
are in progress.
Tests on the research and
development project’s firstgeneration unit will be
completed in February 2006.
“Our target is to prove that the
device works seamlessly with
a 6-cylinder Wärtsilä 35SG gas
engine,” says Jaakko Ruokomäki,
System Specialist in Wärtsilä’s
Fuel-Cell Group, who is
co-ordinating practical development work on
GasPac. The innovation is also compatible with
Wärtsilä’s other gas engines. The dimensions of
T E XT: A N N E KY T Ö L Ä
PH OTO : TO MMI T UO MI
the catalyst are tailored for each customer, with
factors such as gas flow and the quality of gas
used influencing module size.
MORE EFFICIENT USE OF GAS
In his previous positions at the Helsinki
University of Technology and VTT Technical
Research Centre of Finland, Jaakko
Ruokomäki also worked on improving gas
quality. According to him, the technique
used in GasPac is based on steam-reforming
technology that was already being employed
in the 1930s. While the original process aimed
at producing hydrocarbons from methane,
the target is now to retain the methane while
breaking down any heavier components into
hydrocarbons and carbon monoxide. In the
subsequent catalytic phase, hydrocarbons
and carbon monoxide react to become
methane and water. The objective is therefore
to increase the methane concentration and,
consequently, the methane count of the
natural gas to the highest extent possible.
“The best thing about this process is that we
don’t lose any gas energy at all, it just changes
form,” says Ruokomäki.
Development of GasPac continues,
with the target for secondgeneration devices being to
reduce the need for water, lower
the feed temperature, improve
the sulphur tolerance of the
process and reduce the size of
the device.
“Wärtsilä engines have
better electrical efficiency
than those of our competitors.
GasPac makes it possible
to apply this benefit to
Jaakko
other related areas,” says
Ruokomäki
Ruokomäki.
[AN ENVIRONMENTALLY-SOUND INVENTION INCREASES THE MARKET ]
GasPac gives Wärtsilä the
opportunity to expand the
market for its gas engines,
since it will be possible to introduce
motors of current design to oil
refineries and power plants which
use gas with a poor methane value.
1.
Since GasPac allows high
electrical efficiency to be
achieved with poor-quality
gas, it is also an ecological
invention as regards energy
production.
2.
Environmental soundness is
further enhanced by the
fact that sulphur
compounds present in the fuel are
removed by binding the sulphur into
a solid form in the desulphurisation
unit. The result is that there are
effectively no sulphur emissions.

Wärtsilä’s passion
for seeking out better
propulsion machinery has found concrete form in a ferry concept
suitable for cruising up and down the Norwegian coast between
small coastal communities. The new concept features a novel
machinery configuration based on dual-fuel (DF) engines using
LNG as the primary fuel. Since the natural landscape in which the
vessel would operate is still almost untouched, an environmentallyfriendly ship solution is essential. The same machinery concept
could easily be applied to other passenger-ship operations such
as short-route ferries and expedition cruise vessels. To be suitable
for the latter purpose, the ship should have a range that can
accommodate cruises lasting more than seven days without
refuelling.
TEXT: OSKAR LEVANDER
As oil prices continue to rise,
using liquified natural gas
(LNG) as fuel for ship power
systems could become more
than just a solution which is
environmentally-sound, it could
also become of considerable
economic interest.
setup featuring twin Efficiency
Natural gas is one of the largest sources of energy worldwide and
at current rates of consumption is expected to last about 150 years.
On an energy basis, known natural gas resources exceed known oil
resources and are widely distributed around the world.
Natural gas is a very safe fuel when the right precautions are
taken. In its gaseous form, it is lighter than air, which means that
should there be a leak, the gas will disperse upwards and not build
up in a ship’s bilges. Also, the ignition temperature of natural gas
is relatively high (600°C) when compared to diesel oil (250°C),
and natural gas is flammable only when mixed with air within a
relatively small concentration range (between 5% and 15%).
In its liquid state, LNG is not explosive, corrosive or toxic.
Possible spillage does not result in any lasting contamination since
the liquid simply boils off as a gas. The low temperatures required
for storage are an issue when talking about the normal steels used
in ship construction, but this problem can be avoided by using
appropriate materials for LNG systems. In overall terms, LNG
machinery can be as safe or safer than conventional solutions using
diesel oil.

ratio (the highest among fossil fuels) means
lower CO2 emissions than with oil-based fuels,
and levels of NOX and particle emissions are
significantly reduced. When natural gas is
liquefied, all the sulphur is removed, and this
means zero SOX emissions.
Calculations made for the new concept
shows a remarkable difference compared to
machinery that uses diesel fuel. As all the
major emissions can be significantly reduced,
the LNG solution is truly environmentallysound. Comparable reductions in CO2
emissions are particularly hard to achieve with
conventional oil-based fuels.
The main problem with using LNG in ships
is the relatively-large amount of space required
for fuel storage. The range demanded of the
new ferry means that very large tanks with a
capacity of 520 m3 are required. Regulations
concerning the location of the storage tanks
are also very strict. Finding suitable space for
them inside the vessel is a clear challenge,
affecting both the ship’s dimensions and
its internal arrangements. In this particular
design, two large LNG tanks are located
down on the tanktop in the centre of the
vessel inside the B/5 lines, as stated in the
classification rules.
NEW ALTERNATIVE SOURCE OF ENERGY
LNG
compartment
(250 m3)
The ferry is equipped with Hybrid Dual
Fuel (H-DF) machinery consisting of two
Wärtsilä 6R32DF propulsion engines and two
9R32DF generating sets. Total installed power
is 10.5 MW, with the engines using LNG as a
primary fuel and MDO as pilot and back-up
fuel. When manoeuvring and at low speeds,
operation is diesel-electric. At higher speeds,
the mechanical propulsion engines are engaged
in combination with the electric motors to
boost shaft power.
The vessel’s machinery is designed
according to an Emergency Shut Down (ESD)
philosophy. This means that if there is a gas
leak in one of the engine rooms, the gas supply
is cut off and the engines are switched over to
diesel mode. If the leak continues, the entire
room is shut down. This in turn requires full
redundancy in the machinery.
LNG is a new alternative source of energy
for ship power. The new ferry concept
shows how this new fuel can be efficiently
integrated into ship design and obtain the
environmental benefits on offer. The new
concept also offers lower operating costs than
those for a similar ship using low-sulphur
diesel oil. Although some additional space
for LNG storage is required, this can be
taken into account from the beginning of the
design process, and the cost is small when
weighed against the enormous reduction in
emissions that can be achieved.

Clearly fulfilling the need
for intermediate and
peaking power, and with
its very rapid start-up
qualifying for use as
ready reserve, the
Western 102 power plant
is part of a new era of
modern gas power
plants in the US.
LOCATED NEAR RENO, Nevada, Western 102 is a 115.6
MW facility owned by Barrick Goldstrike Mines Inc. It
joins the Wärtsilä-supplied Plains End (111 MW) and Red
Bluff (50 MW) plants as suppliers of electricity to the US
transmission grid. Declared commercial in early December
2005, Western 102 is demonstrating the flexibility, efficiency
and reliability of gas engine technology and is the largest
power plant of its type in the country.
Contracted in late October 2004, Western 102 consists
of 14 gensets, each with a rated output of 8.4 MW at site
conditions of 35°C and 1324 metres above sea level. Even
under these stringent conditions, plant output to the grid
is guaranteed to be 115.6 MW. According to Dennis Finn,
Business Development Manager, Wärtsilä North America
Inc., this genset project takes advantage of Nevada Assembly
Bill 661, which allows industrial customers of the local utility
to leave the grid if they meet several requirements. Among
the most important of these is to have a hard generating asset
located within Nevada which provides the industrial user
with electricity, and any such asset must meet the utility’s
largest single-component failure criteria.
[ SO LUT I O N ]
High availability. The Western 102 gensets are Wärtsilä
20V34SG, modern natural-gas-fuelled spark-ignition engines
with pre-combustion-chamber (PCC) technology which
employ a lean-burn fuel/gas/air ratio to provide a very low
heat rate in conjunction with very low emissions rates. p

[ SO LUT I O N ]
The units are also equipped with Selective Catalytic
Reduction (SCR) systems for additional NOx reduction and
Oxidation Catalyst for additional carbon monoxide (CO)
and Volatile Organic Compound (VOC) control.
Wärtsilä provided power-plant and engine controls as
an integral part of the design. To facilitate the 10-minute
start-up and loading to full output from all gensets in warm
standby, each genset has the capability of synchronizing
with the grid rather than having shared synchronizers
for a block of gensets. Dennis Finn comments “The 10minute start-up to full load output is important because
it meets the utility’s ancillary services requirements and
provides an additional source of revenue for the owner
of the generating asset. Other technologies provide quick
start-up, but our solution is more reliable and provides it
a higher percentage of the time. We’ve demonstrated that
Wärtsilä technology does this much better than a lot of
technologies, and also better than the other technologies
competing in the intermediate/peaking market segment.”

No process water for engine cooling. The Western 102 power
plant building has two engine halls with seven gensets in
each, separated by a central section that contains the control
room, MV switchgear area, motor-control centre (MCC),
maintenance area, and personnel facilities. The building is a
typical prefabricated type which includes sound insulation for
noise control. Silencers in the charge air piping to the engine
turbochargers and the large vertical silencer in the exhaust flue/
exhaust gas stack provide additional noise control.
Since this is a simple-cycle installation engine, heat is rejected to
the atmosphere via a closed loop cooling system using radiators,
which allows the gensets to reach their guaranteed performance
without consuming process water. To meet the utility-imposed
largest-component failure criteria, the plant has a redundant buss
bar system and redundant step-up transformers and breakers which
allow loss of one transformer without affecting plant output.
The technology supplied for the Western 102 plant is designed
for remote dispatch and regulation by the utility’s automatic
generation control system.

TECHNOLOGY DOES THIS BETTER THAN THE
OTHER TECHNOLOGIES COMPETING IN THE
INTERMEDIATE/PEAKING MARKET SEGMENT.”
solution
Rapid start-up, flexible
operation, negligible use of
process water and a veryimpressive net heat rate
make the genset technology
employed in Western 102 a very
attractive solution.
Technology benefits. Wärtsilä genset technology offered the plant
owner several benefits that led to the selection of this set-up over the
other technologies that are available. These benefits include better
ancillary service, a lower cost to meet the largest-single-component failure
criteria, lower water requirements, guaranteed heat rate and greater plant
flexibility. Also, since the net plant output comes from a group of 14
gensets, the failure of one unit represents only a 7% loss of full-load-rated
output – a significant benefit compared to competing technologies that
feature from just one to three generating components.
Lean-burn, natural-gas-fired reciprocating engine technology does
not require use of water to meet the heat-rate, output, and emissions
guarantees even at the high ambient air temperature and elevation of
Western 102. The only process water consumed is a small amount needed
for washing the engine turbochargers and a small amount used to keep
the closed-circuit cooling-loop water expansion tanks at set point. This
consumption amounts to only some 7.5 litres per unit per week.
“From the viewpoint of providing both ready reserve and spinning
reserve,” says Finn, “We have a heat-rate advantage. And also, something
that is peculiar to the west and particularly to Nevada, is the fact that
we achieve the heat rate without using process water.” This package of
benefits, characteristic of the genset technology, allows Wärtsilä to offer
significant competitive advantages. p

Plant flexibility. Under the 35°C, 1324 m-above-sea-level site conditions, the Wärtsilä
genset technology offers a guaranteed heat rate of 9179 kJ/kWh, which is clearly superior
to any other commercial simple-cycle technology. When gensets are removed from fullpower service to match demand reductions, the technology also provides greater operating
flexibility. Having all gensets in operation at minimum load maximizes the spinning
reserve. The efficiency of individual gensets at 50% of rated load is approximately 88% of
their efficiency at full load. Another example of the technology’s flexibility is that it has the
ability to carry full plant output with only 4.5 bar fuel-gas pressure.
“It’s important to understand that this is relatively-new technology which was
really not commercialised until the mid 1990s,” says Finn. “That’s not because the
hardware wasn’t there, it’s been there for a hundred years. It took the development of
very sophisticated electronic controls to operate the genset with natural gas in leanburn mode, something which makes the heat rate achieved the best in the world as
far as simple-cycle technology goes. Secondly, electronics were required to keep the
gas-fuelled engines stable in lean-burn mode, since the operating range in which
the engine produces both high efficiency and low emissions is very narrow. Without
sophisticated electronic control on the fuel, air and individual cylinders, the high
performance offered by these engines would not be possible.”
Flexibility is also demonstrated by the plant’s ability to cycle from shutdown to full
load and back to shutdown conditions several times each day without affecting the
equipment or adding to the maintenance hours.
As well as supplying the gensets for Western 102, Wärtsilä was also the project
engineering, procurement and construction contractor, providing a single point of
responsibility for both schedule and performance.

nergy is the lifeline of a modern hospital. Since most life-support equipment runs on
electricity, an uninterrupted power supply is of the utmost importance. Ever-increasing
fuel prices mean that the costs of energy are substantial and any possibilities for
achieving savings should be welcomed. The demand for electricity, steam, hot water, heating
and cooling in a hospital makes it an ideal application for cogeneration, and this type of
installation can also provide the no-break and emergency-power functions.
Many hospitals have already acquired years of satisfactory experience in cogeneration.
Successful results depend on dedicated planning and engineering and installation methodology
which incorporates comprehensive information exchange with other users. An integrated
approach to operations and maintenance can further help in obtaining optimum performance.
Extensive demands on energy
Modern hospitals are completely dependent on energy. Proper medical care of many
patients in a limited space demands ultimate standards of cleanliness and a wellconditioned internal climate. The bathing of patients requires that clean hot water is always
available. Hot water and steam are also required for additional services such as providing
meals, sterilising equipment and cleaning textiles. Electricity fulfils a crucial role in life56 Twentyfour7. 1.06
support systems and in operating theatres,
and the lighting of common spaces is a major
consumer of electrical energy. Electricity is
also used to power productivity-enhancing
equipment such as patient lifts, adjustable
beds and elevators. Communication systems
for data handling and information exchange
all run on electricity. The energy supply in a
hospital is so important that it is subject to
many official regulations designed to ensuring
its permanent availability.
Heating and cooling depend
on the local climate
A typical hospital with 750 beds and a
polyclinic can have an average electric
load of close to 1.5 MW, with a base load
of 1 MW and a peak load of 3 MW. The
levels of heating and cooling required are
heavily dependent on the local climate and
the thermal properties of the building. For
a moderate climate such as that in The
Netherlands, the installed power for heating

would be required to generate the 4.05 MJ of
heat. Relying on separate generation rather
than cogeneration would therefore result in
4.5/9.0 x 100 = 50% extra fuel consumption.
Cogeneration therefore results in a substantial
reduction in the use of fossil fuel, albeit on a
national basis.
totals some 10 MW and for cooling 1 MW.
The variation in heating load is much higher
than the variation in electrical load: if the
average heat load is 2 MW, the peak load can
easily be 10 MW during cold winter spells. If
natural gas is available, it is often the preferred
fuel because of its price level, easy handling
and clean burning characteristics. Hospitals
also perform a crucial function during major
disasters that could be accompanied by failure
in the supply of natural gas and electricity
from the grid. For this reason, the availability
of back-up liquid fuel for a diesel engine
powered generator and for dual-fuel burners in
the boilers is often a mandatory requirement.
“Cogeneration
should be the
standard solution
for energy supply
in hospitals.”
Advantages of cogeneration in hospitals
As already mentioned, hospitals have a
permanent demand for electricity, steam, hot
water and heating/cooling. From the fuelutilisation viewpoint, this is an ideal application
for cogeneration. In most cases, the demand
for heat is such that it exceeds the demand
for electricity. Consequently, a cogeneration
installation can be dimensioned for at least the
base load of electricity. If a substantial quantity
of running hours can be made for the additional
electricity demand, or if surplus electricity can
be sold at an attractive price, consideration can
be given to a larger installation.
The energy savings from cogeneration can
be calculated (see Figure 1). With a presumed
total efficiency of 85% and an electrical
efficiency of 40%, each kWh of electricity is
accompanied by 4.05 MJ of heat that can be
put to useful application. If this heat was not
available, it would have to be produced by a
separate burner-boiler combination having
an efficiency of approximately 90%. That
means that an extra fuel input of 4.5 MJ
No-break and emergency power functions
It can be argued that cogeneration involves
additional capital investment in generators
and that the associated costs should be
counterbalanced by net savings on energy
bills. For a hospital however, the nobreak function offered by a cogeneration
installation is an additional benefit in this
respect. The supply of electricity is so crucial
that a no-break and emergency power
function will always be needed. Cogeneration
installations can perform these tasks without
problems. Gas engines with per-cylinder fuel
supply have such good stability and loadstep response that the quality of their power
is more than adequate for sensitive medical
equipment. Under normal circumstances, the
generators of the cogeneration installation
run in parallel with the grid. If the grid fails,
the engine-driven generators stay on-line
even though some less-important user groups,
such as some lighting functions, may be
switched off temporarily. Vital instruments
involved in surgery, patient monitoring and
life-support systems, and communication
systems must certainly remain connected.
The presence of a cogeneration installation
therefore reduces the level of investment in
back-up equipment.
All factors considered, installations
that improve the efficiency of fuel use
are so beneficial for national economies
that governments are inclined to support
them with subsidies or even make their
employment mandatory. The increasing
scarcity of fuel all over the world will
certainly make energy more expensive in the
future. Hospitals are investments which are
intended to last many decades and selecting
the best options for energy supply is therefore
important. These considerations mean that
cogeneration should be the standard solution
for energy supply in hospitals.
UMC at the University of Utrecht
The University Hospital (UMC) of the
University of Utrecht in The Netherlands
has more than 20 year experience with gasengine driven cogeneration. The hospital has,
however, recently undergone a significant
expansion and the technology used in its
cogeneration system was old-fashioned
compared to current standards. It was decided
that three new gas-fired units with an electrical
rating of 2.1 MW be installed, i.e. a doubling
of the existing power supply. There is an
existing 3 MW diesel generator which can
take over if the gas-supply fails and in such a
case, the two steam boilers (11 MW each) can
also switch over to diesel fuel. Under normal p

circumstances, the diesel system is only used
during periodic testing.
Reliability considerations revealed that three
gas-engine driven generators operating in
parallel would provide sufficient availability.
In normal circumstances, the public grid is
used as back-up if a generating unit fails.
This is also the case during maintenance
activities, as only one unit is maintained at a
time as remaining engines have to carry the
base electric load. If one of these two engines
develops a problem, the diesel generator can
be added in to ensure that adequate back-up
power is available should the public grid fail.
The combined level of reliability in supplying
electricity is very high. The steam boilers have
sufficient capacity to produce the heat which is
otherwise taken from the gas engines.
The gas engines have electromagneticallycontrolled gas-admission valves on each
cylinder, an arrangement which results in an
unsurpassed step response. If the demand
for power varies when the system is in island
operation (i.e. on emergency power), the
control system instantaneously detects the
change in demand and instructs the gasadmission valves to supply exactly the
amount of fuel which will match electricity
production to demand. This ensures good
frequency and voltage stability.
High supply security
Economic modelling revealed the optimum
running pattern for the three cogeneration
units at UMC, at least for current levels of
electricity and natural gas prices (see Figure 2)
At night, electricity demand is about 3.5
MW. This is covered by running two engines
in parallel at about 83% load. The electrical
efficiency of the units is then close to the
nominal value and there is room for dealing
with positive load steps should the public grid
fail. From 7 am until 11 pm during weekdays,
the tariff for electricity is substantially higher
than it is during the night. In that time period,
therefore, all three engines are run at full load.
From 8 am till 6 pm, electricity has to be
bought in (i.e. ‘imported’) but this is largely
compensated for by some exports early in the
morning and considerably more exports in
the evening. Should the grid fail during the
daytime, electricity production by the two
cogeneration units is sufficient to cover all
preferred users, so there is a high security of
supply, even if one of the three units fails. If
this happens, the 3 MW diesel generator can be
started up to meet the demand. Under current
economic conditions, it is not profitable to

export electricity during the night or to
install additional local power to cover the
daytime consumption peak.
Positive experiences with cogeneration.
Some hospitals have as much as 30 years
of experience with cogeneration and are
now deciding to renew or expand their
installations. Other hospitals are about
to implement cogeneration as a way of
complying with regulations for energy
saving in buildings. Many governments
encourage the use of cogeneration by
“An integrated
learning process
and maximum
information
exchange make
for a very reliable
installation.”
offering financial incentives. European
rulings mean that electrical utilities are
obliged to accept grid-parallel operation.
Cogeneration is certain to be the standard
in modern hospitals.
Modern gas engines as prime movers
for cogeneration installations have good
levels of reliability. They are the result of
reproducible manufacturing processes
that comply with quality standards. Their
running stability ensures good power
quality. For example, the new facility at
UMC in Utrecht has already proven its
ability to act as back-up power in case of
grid failure. With the proper strategy in
respect to the number of generating units
on line and a well-defined maintenance
program, levels of electricity availability
can meet the stringent requirements set by
a hospital environment.
Extensive and inclusive teamwork
brings benefits
Some hospitals are even investigating a gradual
increase of the group of electricity users that
will receive uninterrupted power in cases of
grid failure. The ideal would be that no user
even notices the transition from grid operation
to island operation. Achieving this involves
the combination of good design, careful
testing, and close observance of maintenance
and operational specifications. It appears
that extensive teamwork between operators
and maintenance crews helps in properly
understanding how installations perform.
For this reason, some hospitals avoid any
communication problems by fully integrating
maintenance procedures into operations. An
integrated learning process and maximum
information exchange make for a very-reliable
installation.
In The Netherlands, technical staff in
hospitals have for many years organised
workshops at which the regular exchange of
experiences takes place. The participation
of equipment suppliers and engineering
bureaus in such activities has stimulated
further improvements in existing cogeneration
installations and has also resulted in new
designs. Regular contacts of this type are to be
highly recommended in all countries.
Conclusions
In conclusion, hospitals are an ideal site for
implementing cogeneration because of the
substantial concurrent demand for heating,
cooling and electricity. Considerable savings
in energy bills can be achieved, especially
if governments remunerate the associated
national benefits. Cogeneration installations
have also proven their ability to act as back-up
generators in case of grid failure, a capability
which removes the need for additional
investments in emergency power. For a
successful installation, designers must ensure
that they choose equipment which can deliver
the correct power quality. Planners, designers,
engineering bureaus, manufacturers, installers
and operations and maintenance personnel
should all aim for maximum information
exchange and co-operation in order to achieve
the most satisfactory result. Energy supply for
a hospital is so crucial that problems in project
management cannot be accepted.

Twentyfour7.
A joint project between Wärtsilä
and ItalGreen Energy, the
Monopoli CHP plant is located
in the heart of Italy’s Puglia
olive growing region, and has a
generating capacity of 24MW.
At full output, the three gensets
will consume 45,000 tonnes of
vegetable oil each year.
LIQUID
BIOFUEL
– a viable choice for power generation
since the beginning of social
development, only recently has there been any
substantial research into extracting maximum
levels of efficiency from this energy source.
PART OF OUR LIVES
T E X T: N I K L A S H A G A | P H O TO : W Ä R TS I L Ä

he virtuous circle in Power Generation is the dream of the modern world: a power plant
that is environmentally friendly, that uses renewable fuel, and which uses cash crops
that could help to ease poverty in many of the world’s poorest countries.
This is no longer a dream, it is reality. Italy’s ItalGreen Energy and Wärtsilä have built the
world’s largest power plant fuelled exclusively by straight vegetable oil. Liquid biofuel can be
produced from practically any oil-rich crop - from sunflower seeds to rapeseed and palm oil.
The technology
Although transesterified bio/vegetable oils, also called biodiesels, can be used as fuel in
automotive diesel engines and in medium-speed engines, the price of this refined product is
too high for power production in many markets.
Diesel engines, which are based on compression technology, offer a much more appropriate
route because the oil can be used more or less straight from the crop. This is not a new
concept. In fact, Rudolf Diesel ran his first engine back in 1900 on peanut oil. Economics
clearly play a major role in the decision to generate power from liquid biofuel rather than fossil
fuel, and engine builders have had to overcome a number of technical hurdles.
Controlling fuel temperature is key
When optimizing their plant design, Wärtsilä developed a fuel-feed system which controls
the fuel temperature throughout the power plant. These modifications keep the viscosity of
the fuel stable by preventing overheating and eliminating cold zones which can lead to the
creation of wax.
60 Twentyfour7. 1.06
Since August 2004, two Wärtsilä 18V32
generating sets have generated 16 MW of
power running at maximum efficiency in the
ItalGreen combined heat and power (CHP)
plant in Monopoli, Italy. Installation of a
third engine which went on line in June 2005
increased the baseload power output to 24 MW.
Practically zero emissions of CO2
Even though liquid biofuels have been
around since the beginning of human
social development, it is only recently that
environmental and commercial pressures
have resulted in any substantial research
being carried out into extracting maximum
levels of efficiency for the generation of
electrical power. Factors contributing to the
drive to develop viable liquid biofuel include
international governmental pressure driven by
fear of the effects of climate change, as defined
in the Kyoto Protocol, together with a need to
reduce our reliance on increasingly-expensive
fossil fuels. The use of liquid biomass for
power generation results in practically zero
emissions of CO2 to the atmosphere.
Quite naturally, there has been some initial
resistance from the major oil companies and
it is still difficult to find liquid biofuel at most
roadside filling stations. But liquid biofuel is
already being added to the many fuels available
on forecourts. Although the US has refused to
[ INSIDE ENERGY ]
01.2006.
ratify the Kyoto Treaty, many thousands of
hectares of ‘Corn Belt’ states in the USA have
been producing oil for ethanol production
for several years. Corn (maize) farmers see
this as both a new source of income and a
contribution to the ‘green’ debate. In 2005,
production totalled 4.4 billion gallons, up by
more than 20% over 2004.
Palm oil from Malaysia and Indonesia
During the past decade, the price of palm
oil has been clearly lower than that for other
vegetable oils and it has lately become the
most interesting commodity to use as liquid
biofuel. In terms of production volume,
palm oil is the world’s second most produced
vegetable oil after soybean oil. Palm oil
exports come predominantly from Malaysia
and Indonesia and these two countries can be
expected to maintain their dominant position
in exports of oils and fats, accounting for
45% of total trade.
Although Malaysia is currently the world
leader in palm oil production, that fact that
Indonesia is constantly increasing the size of
its plantations means it is quite likely to take
the number-one position in the course of
the next ten years. Indonesia has focused its
industrial activity on producing crude palm
oil, but that is also set to change as processing
resources are being developed at a rapid
pace. Currently, most of the oil produced
is exported either to Europe or to other
countries in Asia such as India and China.
Optimizing use of the new fuels
Clearly, though, it is up to the major engine
producers to lead the field by ensuring that
they build engines which can optimize use of
these new fuels. In medium-speed engines,
which can run on most qualities of heavy
fuel oil (HFO), it is in the fuel feed systems
that major research has taken place. For
many decades these engines have proven their
worth as electrical power generating sets, as
direct power for marine drives, and for onand off-road equipment in the most extreme
conditions.
Experience built up by engine builders
such as Wärtsilä in the use of filters,
separators, preheaters and coolers places
them in a unique position at the forefront of
technology to develop optimal systems for
extracting maximum power with the lowest
possible emissions.

ItalGreen Energy
I
talGreen Energy is the energy division of the
Casa Olearia Italiana Group (COI), one of Italy’s
leading suppliers of olive and other vegetable
oils. As well as being able to lay claim generations
of know-how in oil refining and treatment
processes, ItalGreen has developed considerable
experience in renewables and biomass-fired
power systems. The company have taken full
advantage of the current opportunities for green
certificates provided by the Italian authorities and
encouraged by EU directives.
Local legislation in Italy encourages the use
of green certificates, one benefit of which is an
electricity selling price fixed for a period of eight
years. By law, all power producers and importers
in Italy are currently required to supply at least
2.35% of their power to the grid using renewable
resources. The amount of power supplied in this
way will progressively increase as the technology
becomes more widely accepted and incentives
encourage more private entrepreneurs to build
and operate their own power plants.
ENCOURAGING ENERGY ENTREPRENEURS
TO TAKE AN ACTIVE ROLE
This policy is of primary importance in Italy’s
energy market. The risk of power shortages, high
electricity prices and demanding environmental
requirements are further factors which
encourage energy investors to take an active role.
In such a context, liquid-biofuel-based energy
production represents one of the best ways of
ensuring the economic viability of this type of
‘green’ energy projects. In addition, the high
overall levels of power plant performance that can
be achieved using medium-speed reciprocating
engines make ‘green’ energy an increasingly
attractive proposition.
Casa Olearia Italiana, located in Monopoli in
the heart of Italy’s Puglia olive growing region,
covers an area of 100,000 square metres
(24.70 acres). The facility produces extra virgin
olive oil, olive oil, and refined pomace oil and
seed oils such as sunflower, corn, soy, peanut,
grape, rape and palm. Monopoli’s specialist
harbour for foodstuffs-oil is one of Italy’s most
active and well equipped.
The warehouse for oil storage is fitted with
more than 100 stainless steel tanks with a
combined capacity of some 60,000 tonnes.
The packaging plant for the company’s own
brands and other international household and
commercial brands is one of the world’s largest.
It has four packaging lines, one of which can
produce 11 items a second. Casa Olearia Italiana
is an ISO 9002-certified company.
THE MONOPOLI CHP PLANT
The Monopoli CHP plant is a joint project
between Wärtsilä and ItalGreen Energy, part
of the COI Group. The first two Wärtsilä 18V32
generating sets were commissioned in August
2004 with a total capacity of some 16 MW. A third
engine, commissioned in June 2005, increased
the plant’s capacity to 24 MW.
It is estimated that the three engines will
consume up to about 45,000 tonnes of
vegetable oil per year when running at full
output. Combustion of liquid biofuels enables
simultaneous generation of electricity and heat
without sulphur emissions and zero consumption
of fossil fuel. Located inside the existing vegetable
oil refinery, the Wärtsilä-designed plant supplies
both green electricity to the national grid and
steam and power for factory processes. Wärtsilä
was responsible for the fuel tests, detailed
engineering, delivery of the full generating set
package, start-up and erection supervision.
ItalGreen Energy handled the civil works, plant
erection and site activities.
The Green Certificate scheme in the European Union
U
nder the Kyoto protocol, the European Union
committed its Member States to reductions of
8% from 1990 levels of greenhouse gas emissions
between 2008 and 2012. Each country in the EU
has set specific levels and is working towards a
cross-union tradeable system. The details of this
system are still evolving. In Italy’s case, the target
for greenhouse-gas reduction is 6.5%.
A variety of incentive mechanisms, including
Green Certificates, exist for motivating
companies to reach this target. These are
financial contributions at community, national
and regional levels, the renewable-energy
certificate system, and grants of origin. In the
case of the Green Certificate, local Independent
Transmission System Operators have the task
of checking self-certifications and complying
with all the procedural rules. Each power
generation plant that uses non-renewables is
currently obliged to produce 2.35% of its annual
electricity production using renewables. If they
fail to comply with this requirement, they must
buy a Green Certificate for each and every 50
megawatt-hour included in that calculated 2.35%
of annual output.
On the other hand, power companies such
as ItalGreen Energy who produce energy from
renewables will be awarded Green Certificates
at the same rate and can then sell these Green
Certificates to the offending power producers.
In this way, power plants with low levels of
greenhouse-gas emissions beanefit from their
investment twice over: firstly from selling their
electricity to the national grid, and secondly by
being able to trade their Green Certificates.

he offshore and energy industry knows
how to get the best from its engines in
terms of performance and operational
costs – it leaves it all to the engine builder.
For the last five years, Wärtsilä has been
offering this sector both full performance and
operational responsibility for its stationary
engines in places as far flung as Bangladesh,
Columbia, France, India and Kenya, building
up a reference list that now totals more than
2600 MW. Wärtsilä is now looking to expand
service provision in the marine industry.
Cost and performance efficiency
Wärtsilä Operations & Maintenance is
essentially a ship-management system for the
engine room in which five or ten-year, fixedprice service agreements are tailor-made to
keep each customer’s investment both costand performance-efficient throughout an
engine’s lifetime. In a nutshell, the concept
has been designed to ensure safe and reliable
ship operation; to eradicate downtime; to
ensure the performance and monitoring of
both main and auxiliary engines and other
Wärtsilä products; to provide trained and
skilled seafarers; and to ensure rapid response
by maintenance crews wherever and whenever
they are required.
Tage Klockars, Operations & Maintenance
Systems Manager, explains: “Utilizing the
latest technology means that today’s products
are very sophisticated. Training engineers
in the correct use of modern engines is not
an easy task for shipowners and operators.”
A case in point is the fact that although
80% of machinery breakdowns are still
down to human error, this could in time
fall to insignificant levels as more and more
shipowners sign up to the Operation &
62 Twentyfour7. 1.06
Maintenance concept. “Primary drivers in the
ship power industry are running costs and
environmental impact, and one consequence
of this is that the technology becomes
very advanced. Support and back-up from
someone operators know and trust is therefore
essential.”
“An increasing
number of requests
from customers
for long-term
Operations and
Maintenance
contracts are being
received.”
Owners of cruise ships frequently opt for
Wärtsilä’s common-rail engine technology
and the LNG market favours the dual-fuel
alternative, so there are definite winds of
change in the market for this kind of highend, environmentally-sound multifuel
technology. An increasing number of requests
from customers for long-term Operations and
Maintenance contracts are being received.
In late 2005, Blue Star became the first
containership owner to sign up to the scheme
with the nine two-stroke RT-flex enginedvessels in its fleet. It’s almost certain that other
marine industry stalwarts will follow suit.
Centralised management
The Operations & Maintenance concept is
based on two elements: the Part Crew Concept
(PCC) and the Technical Management
Concept (TMC). In both instances, a
centralised, land-based management system
is established to administer the operation in
a way not dissimilar to the way in which a
traditional ship-management company runs
its ships – but in this case it’s the engines and
engineering staff that are managed.
“We centralise all engine maintenance,
scheduling, contract management and
invoicing. This makes it cost effective for
us and for the customer. At the same time,
our network maintenance staff provide close
support so it’s easy for them to be on ship or
at the yard more or less immediately, wherever
and whenever they’re needed,” says Klockars.
Technical management
As part of the Technical Management Concept
Wärtsilä provides a rapid-response crew to
carry out all scheduled and unscheduled
engine maintenance according to an
operational schedule. An exchange parts
system helps in shortening downtime, and
major overhauls are carried out in conjunction
with major maintenance on other machinery
or onboard equipment. Overhaul parts are
taken ashore for reconditioning in Wärtsilä
workshops. All parts are provided by the
engine builder, including all software upgrades
and the maintenance of computer systems.
Technical and operational training can also be
conducted on board when this arrangement
suits the ship operator.
“We charge a fixed price which includes
all spare parts for both scheduled and
unscheduled maintenance, all personnel
requirements, condition-based maintenance
(CBM) and monthly reporting, on-line
monitoring, maintenance management and
the coordination of all people and tools,
and onboard inventories,” says Klockars. All
Wärtsilä’s on-line services are incorporated
into the PCC and the TMC concepts.
[ INSIDE MARINE ]
01.2006.
Cruising companies can focus on their core
business while Wärtsilä takes care of the
engines, equipment and associated servicing.
No additional crew positions
The Part Crew Concept (PCC) adds a further
dimension to the scheme in that Wärtsilä
provides part of the onboard engineering
team. There are no additional crew positions
and crew costs for the ship owner or operator
are not increased.
“We provide a Second Engineer, an
Electronics Engineer and junior engineers,
all of whom sail with the ship during normal
routine operations. They provide specialist
skills and have access to all our technical
services, on-line services, documentation and
expertise. Although employed by Wärtsilä,
they fall under the responsibility of the
ship’s Chief Engineer who involves them in
all onboard duties so that they fulfil their
traditional roles” says Klockars.
When customer opts for the Part Crew
Concept, the engine builder takes complete
responsibility for Wärtsilä engines and
products and can provide performance
guarantees. “This is performance-based ship
management,” says Klockars. “Wärtsilä’s
Operations & Maintenance service offers
shipowners significant savings in operational
costs. When we‘re able to guarantee optimum
performance, further savings in lube and
fuel oil consumption can be achieved as
we can optimise how the engine performs.
Also, having optimum performance data
means we can reduce spare-part requirements
since wear and tear on engine components
is reduced. Off-hire time and human error
are significantly reduced if not eradicated
completely.”
“Wärtsilä’s
Operations &

addition to the increased
demand for equipment, there is
a drive for offshore activities to
move to deeper water. Operating in these
conditions requires that offshore structures be
dynamically positioned (DP) and these units
thus require their own propulsive power. As
it is the driving force, propulsion equipment
plays an important role in the successful
operation of an offshore installation.
This article takes a closer look at this type
of propulsion equipment, the Steerable
Thruster.
Wärtsilä thrusters have their origins in
Lips offshore thruster design. First delivered
in 1967, the Lips thruster has been further
developed to have a power range of
800-7000 kW and comply with the highest
requirements for offshore installations.
Wärtsilä offshore thrusters are employed
in heavy-duty seagoing applications such as
semi-submersible drilling rigs, drilling ships,
cable layers, research vessels, and product
tankers. The Wärtsilä offshore thruster
range covers all types of thruster. To ensure
it fulfils the operational requirements of
an offshore application, the design criteria
for each type and size of Wärtsilä offshore
thruster focus on:
1. Using components suitable for continuous
operation in heavy offshore conditions,
2. Ensuring reliability and durability to
minimize down-time, and
3. Providing a lifetime of at least of 25,000
hours at full continuous load (i.e. at 100%
power for 100% of the time)
Design of the Wärtsilä thruster also
involves a modular approach which means
that standardized sub-assemblies can be used
to fabricate different types of the same size
of thruster. This approach means that the
following types are available:
1. Modular Thruster in weld-in, bolt-in
or can-mounted execution
2. Retractable Thruster
3. Containerised Thruster
4. Underwater (de)mountable thruster
All these thruster types are available in
input power ratings of up to 7000 kW and
can be supplied with either fixed-pitch
propellers (FPP) or controllable-pitch
propellers (CPP). Nozzles are commonly used
in DP applications to increase thrust, but
thrusters can also be supplied without nozzles
for specific applications.
Reliable and durable
As already mentioned, the design philosophy
in Wärtsilä thrusters focuses on ensuring
reliability and durability, both of which are
important in ensuring availability of the
system and minimizing downtime. All aspects
of Wärtsilä thrusters cannot be fully described
here, but a few key features are mentioned
below.
Transmission parts (i.e. gearwheels and
bearings) are designed for continuous running in
dynamic positioning conditions. All gearboxes
are fitted with a spiral-bevel gear set, made of
special high-quality forged steel, case-hardened
and fine-machined after hardening to Class 6 DIN 3965 - (H.P.G. process) or better.
Performance requirements demand that
thrusters incorporate a large number of antifriction bearings. Every Wärtsilä azimuth
thruster is fitted with separate bearings that
take axial and radial loads. This ensures
long bearing life. The pinion shaft is also
supported on both sides of the pinion wheel,
function of a steerable thruster consists of a
hydraulic powerpack connected to a number
of hydraulic steering motors. To ensure
redundancy in the system, the powerpack is
equipped with two 50 % capacity pumps that
run at the same time. If one pumps fails, the
steering capacity that remains is sufficient to
ensure safe operation.
Lubrication oil
The propeller gearbox in a steerable thruster
is completely filled with lubrication oil. Each
thruster has single lubrication pump which
takes suction from the lowest part of the
thruster. This ensures optimal circulation of
the oil, and also has the advantage that should
water enter the unit, it will be immediately
noticed as the suction is from the lowest part.
As the circulation of oil is not critical, only
one pump is supplied for each unit. A header
tank is provided to ensure positive pressure
across the seals against the surrounding
seawater. For semi-submersibles that have a
“RELIABILITY
AND DURABILITY
ARE THE BASIS
FOR DESIGN.”
an arrangement which ensures that there is no
deformations in loaded conditions and that
tooth contact between the pinion and crown
wheels is optimal under all load conditions.
Sealing system
A good sealing system is essential for troublefree system operation. A high-quality triple-lip
Wärtsilä viton seal is therefore installed on the
propeller shaft. A ceramic coating is applied
over the full length of the liner. As an option,
the sealing system can be extended to a 4BL
seal (i.e. four viton sealing rings) with special
monitoring possibilities.
A triple lip seal is installed between the
rotating steering pipe and the stationary
support pipe. An extra-heavy-duty type of lip
seal is fitted at the outside to prevent debris
from entering the area between the support
and steering pipes.

different draft in transit and operation, this
system is extended with either an extra (i.e.
higher) header tank or a single header tank
with adjustable pressurised air to compensate
for the difference in water pressure at different
droughts.
Underwater mountable thrusters
A type of thruster widely used on semisubmersible drilling rigs and drill ships is
the underwater (de)mountable thruster. The
first Lips thruster of this type was delivered

rigs at Keppel Fels in Singapore.
Keppel Fels, a world leader in the
construction of offshore jack-up drilling rigs,
semi-submersible platforms and other offshore
facilities for the oil and gas industry, ordered
a complete package of Wärtsilä generating
engines as well as steerable thrusters in August
2005.
The rigs are being built for the Danish
company AP Møller-Mærsk A/S and are of
the DSS21 design developed by Keppel and
Marine Structure Consultants. They will be
employed for development drilling in deep
water down to a depth of 3000 metres and
are intended for all-year-round operation in
regions off the coasts of West Africa, Brazil,
the Gulf of Mexico ans southeast Asia.
Delivery of these semi-submersible rigs is
scheduled for 2008 and 2009.
Each dynamically-positioned semisubmersible will be equipped with eight
Wärtsilä Steerable Thrusters of underwater
(de)mountable design. The input power for
each unit is 4000 kW at a variable input speed
of 0-600 rpm.
To increase thrust in both DP and transit
conditions, the thrusters are equipped with
Wärtsilä High Efficiency nozzles. To reduce
interaction between the thrusters and between
thruster and hull, the nozzles are tilted so
that the jet produced leaves the thruster at an
angle.
A special feature of these steerable thrusters
are the quadruple seal arrangements on the

propeller-shaft seals. These seals are of the
Wärtsilä 4BL type and have four viton sealing
rings running on a ceramic-coated liner. This
multi-barrier seal has two sealing rings facing
the water and two seals facing the oil. There
is also a special connection for monitoring
to allow early detection of any possible seal
leakage.
In addition to the thrusters, the DSS21
rigs will be equipped with eight 16-cylinder
Wärtsilä 26 generating sets having a combined
electrical output of 39,920 kWe.
The reliable partner
Wärtsilä has a long history of supplying
steerable thrusters. It also has the in-house
hydrodynamic expertise required to make a
success of offshore projects. With more than
35 years experience in steerable thrusters,
Wärtsilä is the reliable partner in the
demanding offshore market.

NSB CONTAINER FEEDER
NEWBUILDINGS OPT FOR A
MEDIUM-SPEED SOLUTION
NSB sets a new trend with a
medium-speed solution for a 2000TEU containership.
GERMAN SHIPOWNER
T E X T: PAT R I K W H E AT E R | I L L U ST R AT I O N : W Ä R TS I L Ä
R
eefer containerships and four-stroke
diesel engines do not usually form
part of the same sentence, but it’s
an increasing trend as more and more
newbuildings of this shiptype show interest
in using four-stroke engines.
Largely as a result of burgeoning worldwide
capacity, shipowners with container feeder
newbuildings of up to 2000TEU in mind are
looking for alternative means of propulsion
rather than wait for a vacant slot at the
two-stroke engine-builders yard. ReedereiNSB is taking the lead.
While this shipowner is not the first
operator to opt for a medium-speed solution
for such a ship, it is perhaps the most
prominent as it has a fleet of more than 40
containerships capable of carrying between
1000 and 6750TEU. Reederei-NSB has
selected ten 9-cylinder in-line Wärtsilä 46
four-stroke engines for a series of five
2100TEU containership newbuildings being
constructed at the Aker Ostee shipyard.
Wärtsilä signed an agreement with the
shipyard last year in May and will deliver the
first two 10,395 kW engines to Hull No. 136
in October. To each ship the contract also
includes supply of three 9-cylinder Wärtsilä
Auxpac 20 generating sets, each with an
output of 1600 kWe. The first vessel is
scheduled for delivery in March 2007.
Jan-Anders Backman, General Manager at
Wärtsilä, Ship Power, 4-stroke business, says
this type of installation offers owners a host
of benefits and is a more flexible, compact
solution.
The lower height of the four-stroke
engine alternative permits a much smaller
engine room and lower deck head than the
conventional cathedral-engine configuration,
freeing up valuable space for cargo. This saving
of space is clear in the case of the NSB ships
– the initial drawings depicted a 1900TEU
vessel but this has since been increased to
2100TEU, with an appropriate increase in
ship length from 190 metres to approximately
210 metres.
Cost savings
Commenting on the benefits, Backman says
“With a two-stroke engine, the power ratio
is normally optimised to run on a higher
maximum continuous rating of say 80-90% to
drive a fixed pitch propeller. With the NSB
vessels, two four-stroke engines will drive a
single controllable pitch propeller through a
twin-in/single-out reduction gear. If the vessels
are operating at low speed or in light ship
conditions they can run just one engine.”
“This means less fuel is consumed than with
a traditional two-stroke engine because a fourstroke will always be running in its optimum
speed range. With this arrangement you can
run one engine and simply reduce the pitch of
the propeller instead of having to lower engine
rpm as you would in the two-stroke engine
and fixed-pitch propeller solution. Further
cost savings can be made on the lube oil front
as two-stroke engines require that cylinders are
lubricated by the system oil.”
With a four-stroke engine, the lube oil is
treated outside the engine by continuous
separation. On its way to the engine, oil passes
through a lube oil cooler, a full-flow automatic
filter unit and a safety filter which provides
final protection. For the purpose of runningin, provision has been made for the mounting
of special running-in filters in the crankcase in
front of each main bearing.
Further cost savings will come when vessels
are operating in and out of Ship Emissions
Control Areas (SECA). In May 2005,
MARPOL Annex VI came into force setting
limits on sulphur oxide (SOx) and nitrogen
oxide (NOx) emissions from ship exhausts,
prohibiting deliberate emissions of ozonedepleting substances. The introduction of this
ruling means that engine lube oil may have to
be changed to be compatible with low-sulphur
bunker fuel when a ship enters a SECA. In
contrast to ships operating two-stroke engines,
Reederei-NSB’s newbuildings will not have
to carry two types of lube oil for situations
when the engine is changed from high- to lowsulphur-content fuel: four-stroke engines can
temporarily run on the same lube oil during
operation with both types of fuel.
PRINCIPAL PARTICULARS OF THE CONTAINERSHIP NEWBUILDINGS
The use of 4-stroke engines frees up valuable
space for cargo.

January 2006, two ships
entered service with the first
RT-flex50 low-speed engines:
the 37,000 dwt product tanker Aristidis
and the 19,625 tdw geared bulk carrier
Credo. Both passed their sea trials with
flying colours, and then sailed on their
maiden voyages.
Aristidis, the first to be delivered, was
built for Barclay Shipping Ltd of Greece
by Hyundai Mipo Dockyard Ltd, Korea,
and left the shipyard on 7 January. Credo,
built by Shanghai Edward Shipbuilding
Co Ltd in China for its Swedish owner
Rederi AB Donsøtank, was scheduled
to leave the shipyard at the end of
January. Both vessels are equipped with
a 6-cylinder Wärtsilä RT-flex50 engine
having a maximum continuous power of
9720 kW at 124 rpm. Manufacture of the
engines was subcontracted by Wärtsilä
Corporation to its licensee Diesel United
Ltd in Aioi, Japan.
The Aristidis has overall dimensions
of about 184 m long, 27.4 m beam

and 17.2 m deep, with a design draught of
9.8 m and service speed at that draught of
approximately 15.3 knots. Built to Ice Class
1A Super, the Credo is 158 m long overall,
has a beam of 24.6 m and is 13.5 m deep with
a design draught of 9.0 m. For the Credo,
Wärtsilä also supplied a 5.5 m-diameter
Wärtsilä Lips controllable-pitch propeller,
three 4-cylinder in-line Wärtsilä 20 diesel
generating sets, PTO tunnel gear and an
associated 2000 kWe alternator, and a Wärtsilä
Lipstronic propeller-pitch control system.
The new RT-flex50 common-rail lowspeed engine has received positive acceptance
in the market with 41 engines having been
ordered by the time the first two went into
service. Engines have been ordered for
newbuildings contracted with shipyards
in China, South Korea, Germany, Japan,
Croatia and India for a variety of owners in
China, Greece, Scandinavia, Germany, India
and The Netherlands. These newbuildings
include general cargo ships and bulk carriers
in the range 20,000–53,800 dwt, product and
shuttle tankers of 37,000–52,500 dwt, car
carriers and 17,000 m3 LPG carriers.
The RT-flex50 has been tailored exactly to
the propulsion requirements of various sizes
of bulk carriers in the handymax to panamax
size range, product tankers and feeder
container vessels. With five to eight cylinders,
the engines cover a power range of 5800 13,280 kW at 99 - 124 rpm. A key feature
of RT-flex50 engines for all such ship types is
that they allow a compact engine-room design.
Owners are proving to be very interested in
the special benefits of electronically-controlled
common-rail systems for fuel injection and
valve actuation in engines of this size, especially
the great flexibility in engine setting. The
resulting benefits are lower fuel consumption,
lower minimum-running speeds, smokeless
operation at all running speeds, and better
control of other exhaust emissions.
RT-flex system is adaptable
The RT-flex common-rail concept, already in
service in engines of 960, 600, 580 and now
500 mm bore, has proved readily adaptable to
widely-different cylinder sizes. Although the
common-rail system has been simplified for the
RT-flex50 compared to the systems in the larger
RT-flex engines, reliability and safety have been
given the utmost priority in its design. There is
“Owners are very
interested in the
special benefits
of electronically
controlled commonrail systems.”
still adequate spare capacity and duplication for
redundancy in the supply pumps, main delivery
pipes, crank angle sensors, electronic control
units and other elements.
The rail unit in the RT-flex50 is arranged
on the upper platform. The fuel rail is a
single-piece pipe on which are mounted the
injection control units (ICU) for individual
cylinders. This single-piece design reduces the
number of flange joints and simplifies trace
heating and insulation. Each ICU on the
fuel rail serves just two fuel-injection valves
in its corresponding cylinder cover, with
independent control of each fuel valve.
The supply unit is neatly arranged on a gear
drive from the crankshaft thrust collar, with a
single intermediate gearwheel. Engines with five
or six cylinders have two fuel supply pumps and
two servo oil pumps. Engines with seven and
eight cylinders have three fuel supply pumps.
RT-flex engines are able to run in a very
stable manner at very low speeds, slower than
camshaft-type engines. This is made possible by
the precise control of fuel injection, optimised
injection pressures, optimised valve timing, and
shutting off individual injectors at low speeds.
RT-flex engines can run without smoking at
12% of their nominal speed or even slower.
This was demonstrated when, during sea trials,
the main engine in the Aristidis was able to run
stably at 15 rpm.
The RT-flex system gives important benefits
in environmental compliance. The most
obvious is smokeless operation of RT-flex
engines at all engine speeds. The flexibility of
the RT-flex system also allows a good balance
between fuel consumption and compliance
with NOx regulation in the MARPOL 73/78
convention.
By allowing injection pressures to be
optimised at all loads, RT-flex engines
consume less fuel at part load than
conventional camshaft-type engines.
Advantage has been taken of the complete
flexibility in fuel injection and valve operation
allowed by the common-rail system to offer,
through Delta Tuning, even lower specific fuel
consumption at less than 90% load.
Some design features
A close look through the design of the
RT-flex50 confirms its similarity to other
Wärtsilä RTA and RT-flex engines. It is
designed throughout for structural safety, high
reliability and long times between overhauls,
which are expected to be required after a
minimum of three years’ running.
For example, the RT-flex50 has the latest
piston-running features which allow very
low cylinder-lubricating-oil feed rates
(0.9–1.1 g/kWh) but with very low wear
rates. These features include fully-deephoned cylinder liners, chromium-ceramic
top piston rings, chromium-plated piston p

in the lower part. Losses of system oil are
minimised as all scraped-off oil is recirculated
internally to the crankcase.

by eight elastic studs. It has a single central
exhaust valve housed in a bolted-on valve cage.

ring grooves, an anti-polishing ring at the
top of the liner, optimised cylinder-liner
surface temperatures, and optimised cylinder
lubrication using the long-proven loadcontrolled accumulator system.
The scavenging system employs the latest
high-efficiency turbochargers. Particular
care has been taken to ensure efficient water
separation after the scavenger air cooler.
The high-efficiency separator is located in
an underslung air receiver so that air swirl
aids water-droplet separation. Ample

is very sturdy with low stresses and high
stiffness. The double-walled bedplate has an
integral thrust bearing. The double-walled
column has thick guide rails for rigidity

The main, bottom-end and crosshead
bearings all have white-metal running
surfaces. The crosshead has a full-width
lower-half bearing with the crosshead pin
being of uniform diameter.
The piston-rod gland is of a proven design
with highly-effective dirt scraping action in

systems now incorporated in RT-flex engines.
The engines completed the shop tests with
excellent operating performance results. The typeapproval tests were passed on 13 August 2005.
Sea trials for both vessels proceeded
according to schedule with no major
engine-related problems. The usual minor
adjustments to the WECS electronic control
systems were made since the actual response of
the engine to ship and propeller in shipboard
operation cannot be fully simulated during
shop tests.
The only unexpected feature of the RT-flex
system was the higher-than-anticipated
consumption of compressed air for building
up rail pressures when starting. In all other
respects both engines started well and
demonstrated very good low-speed operation,
with stable running at speeds down to 15 rpm.
After completion of the sea trials, a detailed
inspection was made of the engine onboard
Credo and one cylinder in the engine was
opened for examination. All running parts
were found to be in good condition. The
piston crowns had the heavy carbon deposits
that are usual after low-speed running but no
deposits were found below the top rings. The
piston rings and cylinder liners were all in
good condition.

What to do and say – and what not to do!

“WHAT I USUALLY TAKE WITH ME when I’m travelling is a dictionary and
a traveller’s guide – Lonely Planet for example. The last one I bought was
the guide for Indonesia. In total, I have about five dictionaries and some
eight travel guides. For longer trips, I take books by Tom Clancy, David
Baldacci and similar writers.
It’s my experience that people are really appreciative it if you can speak
some basic words in their language, if it’s not English. Traveller’s guides
tell something about the country’s culture and history. This really helps in
building a good relationship with customers.
It’s handy to know specific customs, and also things that you should
NOT do. In the case of Indonesia, it was pretty good to know what
had happened during the Dutch colonial period, and especially how
Indonesians view that period nowadays. I really saw that our customers
appreciate the fact that you know something about their nation.
I usually spend about an hour each day studying during the first week
of a trip. After that, I check the guide every now and then, and also when I
have the time to go somewhere on a Sunday – if working on Sunday isn’t

ALTHOUGH LEARNING how to handle radio-controlled cars
is easy, the possibilities for trimming and enhancing their
performance make it a challenging hobby, even for people
who have plenty of experience. And those who want to get
everything possible out of their cars build them from scratch. As
construction of a real competition model demands more waking
hours than there are in a weekend, hobbyists desperate to get
going purchase their toys ready made.
There are two schools of thought among radio-control
enthusiasts concerning power sources. One swears by
electric motors, for the other, liquid-fuelled motors are the
only possible choice.
Electric motors get their power from rechargeable battery
packs. Today’s motors are efficient and a single charge can
provide 10-30 minutes driving time. As recharging takes about an
hour, it’s a good idea to have two or three packs with you so that a
shortage of current doesn’t cut your driving session short.
Electric motors are considered foolproof. Safe for use by young
hobbyists, they are also almost silent. Liquid-fuel motors use a
combination of methanol, nitromethanol and oil which is sold
ready mixed. Each tankful provides 15-30 minutes driving and you
can start immediately after refuelling.
Liquid-fuelled motors usually
promise better performance, and
for dedicated enthusiasts, it’s the
combination of noise and smell that
make model-car racing feel real. Each
engine’s ability to perform depends
on a reliable fuel supply, a glow plug
in good condition, and a carburettor
that’s adjusted correctly.
The massive wheels of the Giga
Crusher Twin .26-Engine 4WD
Monster Truck are driven by two
liquid-fuelled motors, each of which
has its own fuel tank. Together, the
two motors produce five horsepower.
As the chassis has double wishbones
and twin shock absorbers on each
wheel, it should be able to withstand
the most punishing demands of its
tearaway drivers.
