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.

TEN PROJECT PROGRESS

KEY FACTS FPSO facility capacity 80,000 bopd

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. CHARLES DARKU MANAGING DIRECTOR, TULLOW GHANA LTD.

I would like to recognise the efforts of our major contractors and their subcontractors in keeping the project on schedule. Fabricating the equipment for a complex deepwater development is no mean feat and requires foresight and flexibility to adapt to changing circumstances and new challenges on a weekly basis.

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.

FPSO 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.” DR. NANA LORDINA MAHAMA GHANA’S FIRST LADY

MODEC trainees onboard the TEN FPSO, Singapore

GHANAIAN 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.” GIDEON AGYEMAN OPERATIONS READINESS & ASSURANCE ENGINEER, GNPC (ON SECONDMENT WITH TULLOW)
