McDermott International and Baker Hughes, a GE company (BHGE) have been awarded subsea umbilicals, risers and flowlines (SURF) and subsea production system (SPS) equipment contracts by BP for the Greater Tortue Ahmeyim natural gas project, located offshore Mauritania and Senegal.
McDermott was awarded a engineering, procurement, construction and installation (EPCI) SURF contract. McDermott plans to use its upgraded Amazon vessel, DLV 2000, North Ocean 102 (NO 102) and third-party vessels to support installation scheduled to begin in late 2020. The Amazon modifications are scheduled to be completed before the installation campaign begins and will include a multi-joint (hex) J-Lay system to handle the most challenging ultra-deepwater projects as well as the addition of a multi-joint facility, dual pipe loading cranes and additional power generation. McDermott-designed pipeline and riser structures will be fabricated at its yard in Batam, Indonesia.
BHGE is demonstrating the benefits of early-engagement and collaboration – some of the key components of Subsea Connect – as well as bringing its expertise in deepwater, long-offset gas projects. The company will provide five large-bore deepwater horizonal xmas trees (DHXTs), a 6-slot dual bore manifold, a pipeline end manifold, subsea distribution units (SDUs), three subsea isolation valves (SSIVs), diverless connections and subsea production control systems, specifically designed to enable the future integration of additional wells for the first phase of the development.
“This contract marks a number of firsts: our first significant subsea EPCI project in West Africa; the first project using our state of the art pipelay vessel Amazon; and our support of BP’s first entry into Senegal and Mauritania. This project is also of significant importance in support of our aspirations in this region,” said Tareq Kawash, McDermott’s senior vice president for Europe, Africa, Russia and Caspian. “Our collaboration with BHGE allows us to offer BP an integrated approach that builds on our proven solutions. We look forward, along with BHGE, to deliver this landmark project to BP with the highest levels of safety and quality.”
“Together with McDermott, we will deliver the best-in-class solution to BP with cost-efficiency and industry-leading safety. 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, Subsea Connect,” said Graham Gillies, BHGE’s vice president, Subsea Production Systems & Services. “This major deepwater gas development is strategically important for Mauritania and Senegal’s domestic and global gas supply, and supports the industry’s drive for a more sustainable, lower carbon future.”
Project management and engineering teams from BP, BHGE and McDermott will remain co-located at McDermott’s London offices for this next phase.
