BALLAST WATER MANAGEMENT SYSTEM
Ballast Water Treatment - A Background
Ballast water is taken from one ecological zone and discharged into another by the trading vessels
across the globe potentially causing invasion on local aquatic organism, natural resources and
harming the biodiversity. Maritime community has acknowledged the gravity of the detrimental
impacts that this may have on the local biodiversity, economy or even the human health of
communities in the surrounding areas.
Impending IMO regulations require BWT plants to be installed on most of the existing vessels
around the world.
Cybermarine's systematic retrofit approach ensures the selection of the most suitable technology
that can be integrated into the existing systems and structures and installed in a cost effective
way.
The different technologies for treating the ballast water are:
►
Solid Liquid Separation
o Mechanical Filtration
o Hydrocyclone
o Chemical enchantment (Coagulation / Flocculation)
►
Chemical Disinfection
o Chlorination
o Electro-chlorination
o Ozonation
►
Physical Disinfection
o Ultraviolet Irradiation (UV)
o De-oxygenation
o Cavitation
For most efficient solution the system shall comprises of two stages of treatment with solid liquid
separation method being followed by either of disinfection methods.
There are several technical, operational, geological and cost considerations to be taken into
account while choosing the right BWM solution.

SCRUBBER AND SCR SYSTEM
Background - SOx, NOx
Need to save and preserve our planet from Environment pollution has been acknowledged by all
right thinking individuals across the globe and Maritime Community has decided to do it's bit
towards reducing Green house gas emissions.
The IMO ship pollution rules set limits for sulfur oxide and nitrogen oxide emissions from ship
exhausts. Every ship is unique and requires a comprehensive evaluation when selecting and
planning for the optimal solution for the reduction of SOx with Scrubbers and NOx with Selective
Catalytic Reduction (SCR) plants.
The new regulations mean that the limit value for sulphur in the Baltic Sea, the North Sea and the
English Channel (so-called sulphur control areas or Sulphur Emission Control Areas [SECA])
has been lowered to 0.1% of weight in 2015 and globally to 0.5% of weight in 2020 or,
depending on fuel supply, at the latest by 2025.
To comply with the regulation, shipping operators should use lower sulphur fuels or install
technical 'abatement' equipment, such as scrubbers, which achieve equivalent results. An
argument in favour of Liquefied Natural Gas (LNG) as fuel, compared to Heavy Fuel Oil (HFO)
is that it will reduce Carbon Dioxide (CO2) emissions by up to 30% and bring nitrogen oxide
(NOx) emissions to 20% of current levels, which will satisfy the upcoming Tier III emission
requirements without further actions.
Maximum Sulphur content of marine bunker fuel based on Annex VI of MARPOL.
Note:SECA stands for Sulphur Emission control area.

SCRUBBER AND SCR SYSTEM
Technologies Available
SCRUBBER SYSTEM
By installing exhaust gas scrubbers, vessels will be able to bring down sulphur content in exhaust
emissions thereby enabling use of fuel currently in usage for marine vessels.
Different types of Scrubber systems are:
►
Open Loop Systems
Seawater alkalinity is used to neutralize the Sulphur in the exhaust and the benefit of the
seawater scrubber is its simplicity; no fresh water or additional chemicals are needed for
operation.
1: SEA WATER COOLING PUMP
2: SCRUBBER
3: WATER TREATMENT UNIT
4: SLUDGE TANK
►
Closed Loop Systems
When the salinity of the water is too low to allow for effective cleaning capability of the
open loop system, closed loop system using fresh water with the addition of a caustic soda
(NaOH) solution is used to neutralize the Sulphur.

SCRUBBER AND SCR SYSTEM
SELECTIVE CATALYTIC REDUCTION SYSTEM (SCR)
The main technique used is Selective Catalytic Reduction (SCR), which converts harmful
nitrogen oxides into harmless nitrogen and water with the aid of a catalyst (ammonia or urea). A
NOx reduction level of above 90% can be achieved.
The systems are still quite bulky and there is room for development. Due to temperature
requirements, the catalytic reactor occupies space in the engine casing close to the engine and in
addition a urea tank and a feed system are required. Other techniques such as fuel/water
emulsions and Humid Air Motor (HAM) also exist, but are not that common in the marine
industry.

DUAL FUEL ENGINES WITH LNG
Background - LNG Retrofits
We are here to help you to retrofit your existing Diesel/HFO fuel propulsion engines and/or
Generator sets with LNG powered engines or Dual Fuel Engines. This will not only cut the
pollution levels in exhaust gas emissions, but will also reduce your fuel spendings. Various
studies show a significant reduction in the NOX, SOX, GHG on converting from contemporary HFO
engines to dual fuel engines. The table below from IACS publication illustrates the point:
NOx emission
SOx emission
Green House Gases
80-90 % reduction
Zero emission
20-25% reduction
The overall retrofits include:
1.
Dual Fuel Engine
The dual fuel engines of suitable capacity can be selected from a host of makes such
B&W, Watrsalia, Rolls Royce to power the vessel by replacing the existing engines.
2.
LNG Storage Tanks
These are IMO Type-C cryogenic tanks of suitable volume to cater to the needs of the
voyage requirements and to the availability bunkering facility.
3.
