TEN Project - Tullow Oil

SPECIAL FEATURE
THE TEN PROJECT
ON
TRACK
On 23 January 2016, following 26 months of fabrication
and testing, the FPSO Prof. John Evans Atta Mills left
Singapore and set sail for Ghana, achieving a major
milestone for the Tullow operated TEN Project.
This milestone was achieved as a result of 17 million man hours
of labour at the Sembcorp Marine shipyard. Main contractor
MODEC supervised the build and will own and operate the FPSO.
The FPSO conversion was one of the most successful projects
of its type ever completed. It was finished on time and on budget
with minimal work left to be completed on the voyage to Ghana.
The departure of the vessel on schedule keeps the project on
course for its July / August 2016 first oil target.

KEY FACTS
FPSO facility capacity

Our operations began in Ghana 10 years ago, and the
TEN Project is Tullow’s second development following the record
delivery of the Jubilee field in 2010. In this annual update of the
project’s progress, we highlight key milestones achieved and
work remaining as we fast approach first oil. The project remains
on time and on budget, demonstrating the operating capability
of Tullow Oil and its Partners.
Operated by Tullow, the TEN Project takes its name from the three offshore fields
under development – Tweneboa, Enyenra and Ntomme – which are situated in the
Deepwater Tano block, around 60 kilometres offshore Western Ghana.
First oil is scheduled for July / August 2016. Following start-up, a gradual ramp
up in production towards plateau is anticipated during the second half of 2016.
The field will add significant low-cost production to Tullow’s portfolio.
The TEN Plan of Development was approved by the Government of Ghana in May
2013. Since then, 11 wells have been drilled and the completions campaign is
progressing well.
Construction vessels began installing subsea production equipment in the fields
in the third quarter of 2015 and the bulk of this work is now complete. When the
FPSO arrives in Ghana in the first quarter of 2016, it will be ready for installation,
hook-up and commissioning.
Tullow and its Partners are confident the project will remain on schedule and
they will deliver the TEN first oil safely and successfully for Ghana.

REALISING GHANA’S POTENTIAL
When the TEN fields come
onstream, it will be a hugely
significant moment for Ghana.
With TEN producing alongside
the Tullow operated Jubilee field,
Ghana will join the select club
of nations with two major oil
producing fields.
It will also be a proud moment
for Tullow Ghana as we move to
operating two developments and
two FPSOs. This will be a new
challenge for Tullow Ghana and
one I am certain we will rise to.
I am extremely proud that Tullow
is at the forefront of unlocking
Ghana’s oil resources and delivering
on our promise to create shared
prosperity. The development of the
TEN fields has led to the creation of
work for Ghanaian companies and
will bring increased revenue to the
Government of Ghana.
The team in Ghana has much to
look forward to in 2016 and remains
focused on creating value for
Tullow, our shareholders and
for Ghana.

Tullow Oil plc 2015 Annual Report and Accounts
The bulk of the subsea production equipment is being
installed by the TS7 consortium (Technip and Subsea7).
The Seven Borealis and Simar Esperanca operated in
the fields in the second half of 2015. Their work scope
included the installation of three Enyenra manifolds,
one Ntomme manifold and the Enyenra and Ntomme oil
production riser bases. At the same time, several pipe
laying vessels completed the installation of flow lines
on schedule.
The project’s umbilicals, which will connect the FPSO to
the subsea equipment and have a total combined length
of over 60 kilometres, arrived in Ghana in November
2015. The installation of the first 10 was completed by
the Viking Neptun in January 2016 and the remainder will
be installed by the Deep Pioneer by the end of April 2016.
The flexible risers, which will carry fluids to and from the
FPSO, are being installed by the Deep Energy.
Following its arrival in the field, the FPSO will be hooked
up to the subsea production system and commissioned.
The final milestone in the campaign, the installation of
all umbilicals and risers, is planned to be completed by
June 2016.

The first equipment to be installed was the FPSO’s nine
anchor piles, which will hold the FPSO in position. These
21 metre high steel cylinders, fabricated in Ghana, were
installed in the seabed by the Normand Installer in
July and August 2015.

NAMING
CEREMONY
The TEN Project FPSO was officially named by Her Excellency the First Lady of
the Republic of Ghana, Dr. Nana Lordina Mahama at a ceremony in Singapore
on 30 September 2015.
The vessel was named FPSO Prof. John Evans Atta Mills after the late President
of Ghana who presided over First Oil from the Jubilee Field.
During the ceremony, Her Excellency paid tribute to the contribution of
Ghanaian artisans to the construction of the FPSO. Ghanaian companies
Seaweld Engineering Ltd and Orsam Ltd fabricated the module support stools
which sit on the deck to support heavy equipment. In addition, the FPSO’s anchor
piles, which will keep the vessel moored in place, were built in Ghana by Group
Five Construction Ghana Ltd. The anchor piles were completed on time and are
already installed in the seabed in the TEN fields, awaiting the arrival of the FPSO.
The First Lady also met some of the Ghanaians who have been working on the
construction of the vessel in Singapore, many of whom will be part of the crew
that will operate the FPSO when it begins producing.
Her Excellency commented: “It has been my great pleasure to officially name
this magnificent FPSO today in honour of a true Ghanaian statesman, the late
Professor Atta Mills.”
“I saw the impressive
facilities onboard
and it gives me
great pride to know
that this state-ofthe-art FPSO will
be producing oil
for Ghana for many
years to come.”

SECONDEES
IN SINGAPORE
The offshore oil business is relatively new to Ghana so, with the exception of those working
on the Jubilee field, opportunities for Ghanaians to gain experience have been rather limited.
The TEN Plan of Development included commitments by Tullow Oil and its partners to
create opportunities for Ghanaians to gain experience and develop skills as integral
members of the project team.
Since 2013, a total of 52 Ghanaians from GNPC, the Petroleum Commission of Ghana
and Tullow Ghana Ltd have spent time on secondment with the TEN Project team in
London, Singapore, Houston and Ghana.
The secondees have worked in a variety of roles including Subsea Engineer, FPSO
Commissioning Engineer, Geologist and Project Finance Manager. They have developed
skills and experience relevant to a major offshore development project, making them
well placed to contribute to future oil developments in Ghana.
In addition, 30 Ghanaian nationals worked on the FPSO conversion with MODEC in
Singapore. Fifteen of these trainees completed the Level 3 General Vocational Qualification
– Diploma in Process Operations. Ten of these Ghanaian engineers were members of the
crew for the vessel’s voyage to Ghana and many more will be part of the team that
operates the FPSO.
“During my time here in Singapore
I have learnt how to piece the various
aspects of a project together to ensure
that it is delivered on time, according
to design and on budget.”
