PARIS – McDermott Marine Construction Ltd. has contracted Nexans to supply around 100 km (62 mi) of subsea umbilicals and components for BP’s Greater Tortue Ahmeyim gas project offshore Mauritania and Senegal.

Nexans’ scope covers management, procurement, engineering, manufacturing, and testing activities for the consignment.

The company will manufacture electrical cables and fiber optics at the Nexans Norway plant in Rognan, while the umbilicals will be developed, constructed, and tested in Halden. Delivery will take place in 2021.

The Tortue field is 120 km (75 mi) offshore in 2,850 m (9,350 ft) water depth. The subsea system will include four wells at first gas, clustered at one drill center, while the production system will be tied back 70 km (43 mi) to a spread moored FPSO at the shelf edge in 100-120 m (328-393 ft) water depth.

Following pre-treatment, the gas will then be exported 35 km (21.7 mi) to a nearshore hub and terminal facility for liquefaction and offloading to LNG carriers.
