BP has awarded contracts to McDermott International and Baker Hughes, a GE company (BHGE) for the Greater Tortue Ahmeyim natural gas project offshore Mauritania and Senegal.

Under the terms of the contract, McDermott and BHGE will provide subsea umbilicals, risers and flowlines (SURF) and subsea production system (SPS) equipment serves for the offshore gas project.

McDermott’s engineering, procurement, construction and installation (EPCI) SURF contract for the Greater Tortue Ahmeyim project is a substantial contract, which the company defines as ranging from $500-750m.

The company plans to use its upgraded Amazon vessel, DLV 2000, North Ocean 102 and third-party vessels to support installation, which is set to start in late 2020.

Before the start of the installation campaign, McDermott plans to complete modifications to the Amazon, including a multi-joint (hex) J-Lay system to handle ultra-deepwater projects.

The work will also involve the addition of a multi-joint facility, dual pipe loading cranes and additional power generation.

Pipeline and riser structures designed by McDermott will be fabricated at the company’s yard located in Batam, Indonesia.

“Our collaboration with BHGE allows us to offer BP an integrated approach that builds on our proven solutions.”

McDermott International Europe, Africa, Russia and Caspian senior vice-president Tareq Kawash said: “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.

“Our collaboration with BHGE allows us to offer BP an integrated approach that builds on our proven solutions.”

As part of the contract, BHGE will provide five large-bore deepwater horizonal xmas trees (DHXTs), a six-slot dual bore manifold and a pipeline end manifold.

The company will also provide subsea distribution units (SDUs), three subsea isolation valves (SSIVs), diverless connections and subsea production control systems.

BHGE Subsea Production Systems & Services vice-president Graham Gillies said: “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.”

On 1 March 2019, BP awarded engineering, procurement, construction, installation and commissioning (EPCIC) contract to TechnipFMC for a floating storage, production, storage and offloading (FPSO) unit to be deployed on the Greater Tortue Ahmeyim project.
