HOUSTONBP has awarded the main contracts for subsea equipment for the Greater Tortue Ahmeyim natural gas development offshore Mauritania and Senegal.

McDermott International and Baker Hughes, a GE company are respectively responsible for the subsea umbilicals, risers, and flowlines (SURF) and subsea production system (SPS).

All three parties are working closely to achieve efficiencies, synergies, and improved delivery times where possible.

McDermott plans to deploy itsupgradedAmazon vessel, DLV 2000, North Ocean 102, and other third-party vessels to support the installation program, which is due to start in late 2020.

TheAmazon modifications, which should be completed before the campaign gets under way, will include a multi-joint (hex) J-Lay system for ultra-deepwater installations, dual pipe-loading cranes, and additional power generation.

McDermott will fabricate the pipeline and riser structures at its yard in Batam, Indonesia.

BHGE will supply five large-bore deepwater horizonal xmas trees, a six-slot dual-bore manifold, a pipeline end manifold, subsea distribution units, three subsea isolation valves, diverless connections, and subsea production control systems.

This equipment will be designed to facilitate future integration of additional wells under the first development phase.

Tareq Kawash, McDermott’s senior vice president for Europe, Africa, Russia and Caspian, said the award was the company’s first significant subsea EPCI project off West Africa.

A year ago, McDermott startedfront-end engineering design with BHGE, the aim being to define the technology and equipment scope for a four-well development.

Project management and engineering teams from BP, BHGE, and McDermott will be based at McDermott’s London offices for this next phase.

The initial subsea infrastructure will connect the first four of 12 wells via production pipelines leading to anFPSO.

Liquids will be removed, and the gas will be transported through a pipeline to the floating liquid natural gas (FLNG) hub terminal close to the coast for liquefaction.
