London-headquartered Subsea 7 has started the load-out of equipment and structures for Tullow Oil’s Tweneboa-Enyenra-Ntomme (TEN) project from Ghana’s Takoradi Port
Takoradi Port, located 225 km off the coast of Ghana, is a principal port for the West African nation. Subsea 7 and steel fabricator Belmet Ghana have been working in the port’s fabrication facility to manufacture fabricated subsea structures, including 25 suction piles and a manifold among others. The manifold, suction pipes and related structures will be installed in the seabed for oil and gas production to begin.
The load-out will be supported from the Takoradi Port, with 18 vessels including tug boats and barges delivering tonnes of equipment and materials, said port officials.
Specifically, Simar Esperanca, which is a Subsea 7 vessel, will set the acoustic transponder array that will enable construction vessels to position with high accuracy for structure installation and pipelay applications, they added. Simar Esperanca will operate in seawater depths of 1,000 to 2,000 metres, install small structures, pre-commission flowlines after installation by pipe-lay vessels, perform pre-lay and post-installation survey as well as complete measurements for connections between flowlines, manifolds and wells.
Through this project for Tullow Oil, Takoradi Port will welcome the world’s most powerful pipelay and heavy lift vessel – the Seven Borealis – to lay thermally efficient pipe-in-pipe flowlines, install suction foundation piles for manifolds as well as install them. The Seven Borealis is Subsea 7’s state-of-the-art strategic enabler, suited to meet the exact requirements of today’s ultra deep and deepwater projects in the world’s deepest and harshest environments, stated the company.
In addition to loading out the subsea equipment, Subsea 7 will also do all its crew changes in Takoradi Port. The London-based construction services company is expected to support the TEN Project for the next seven months, said its officials.
