BP has awarded two companies subsea engineering contracts for the Greater Tortue Ahmeyim gas project off Mauritania and Senegal.
The initial subsea infrastructure connects the first 4 of 12 wells consolidated through production pipelines leading to a floating production, storage and offloading vessel, where liquids are removed and the export gas is pipelined the floating LNG (FLNG) terminal for liquification.
BHGE will provide 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, specifically designed to enable the future integration of additional wells for the first phase of the development.
McDermott will use its Amazon vessel, DLV 2000, North Ocean 102 and third-party vessels to complete its engineering, procurement, construction and installation SURF contract, which is valued at between US$500 million and US$750 million.
BHGE Vice President Subsea Production Systems and Services Graham Gillies said the project supports the industry’s drive for a lower carbon future.
“Together with McDermott, we will deliver the best-in-class solution to BP with cost-efficiency and industry-leading safety,” he said.
“These awards demonstrate the value of early-engagement, collaborative partnerships and holistic project planning, which are very much central to our new approach to subsea developments.”
The FLNG facility is expected to provide approximately 2.5 million t of LNG per annum.
LNG from the project will be shipped for global export as well as for domestic use in both Mauritania and Senegal.
First gas is targeted for 2022.
