Nexans has secured a contract from McDermott Marine Construction for subsea work on the Greater Tortue Ahmeyim natural gas project offshore Mauritania and Senegal.
Under the contract, the firm will deliver around 100km of subsea umbilicals and ancillary hardware for the offshore project. Nexans will be responsible for procurement, engineering, manufacturing and testing of the umbilicals and the ancillary equipment.
Nexans Subsea and Land Systems senior executive vice-president Vincent Dessale said: “The Greater Tortue Ahmeyim contract is of strategic importance to Nexans in maintaining a market position in the West African region as well as being a part of a new, ultra-deepwater gas development.
“It highlights our continuous drive to develop competitive solutions for complex field developments.”
The company will manufacture the electrical cables and fibre optics at its Norwegian facility in Rognan. The production and testing of umbilicals will be conducted at its specialised plant in Halden, Norway. Deliveries of the subsea hardware are slated to take place in 2021.
The Tortue field is situated around 120km off the coast of Mauritania and Senegal in nearly 2,850m water depth. It is developed as the Greater Tortue Ahmeyim project to deliver LNG supplies.
It is jointly developed by a group of companies including BP, Kosmos Energy, Societe des Petroles du Senegal (Petrosen), and Societe Mauritanienne des Hydrocarbures (SMHPM). To be developed in phases, the offshore field is expected to contain more than 25 trillion cubic feet of gas.
Recently, Kosmos Energy and its partners encountered 30m of net gas pay in the Albian reservoir by drilling an exploration well on the eastern anticline of the project development area.
