Nexans has won a contract from McDermott Marine Construction Limited to supply approximately 100 km of subsea umbilicals and accessories for a West African offshore project.
A press release said that the order is for the Greater Tortue Ahmeyim natural gas project, which will be 120 km offshore of the bordering countries of Mauritania and Senegal. Nexans will provide management, procurement, engineering, manufacturing and testing activities for the umbilicals and ancillary hardware. The electrical cables and fiber optics will be manufactured at Nexans Norway plant in Rognan, and the umbilicals will be developed, manufactured and tested at Nexans Norway specialized plant in Halden. The delivery will take place in 2021.
The Tortue field has a water depth of 2,850 m, the release said. The production system ties back some 70 km to a spread moored floating production storage and offloading) unit at the shelf edge at a water depth of 100-120 m. The gas will travel 35 km to a near-shore hub and terminal facility to be liquefied and offloaded to LNG carriers.
Nexans announced that it will provide 27 km of complex umbilicals with power, fiber-optic and hydraulic elements for the next development phase of the most prolific oil and gas field on the Norwegian continental shelf.
A press release said that Phase 3 of the Troll project covers the development of the Troll West structure, which lies in water depths of approximately 330 meters and is located 25 km north-west of the Troll A platform. The contract is from Equinor ASA, a multinational energy company based in Stavanger, Norway.
Nexans Norway will design, manufacture and supply static umbilicals that include high voltage power elements, high-pressure hydraulic lines, low-pressure hydraulic lines, a MEG (methanol and glycol) service line for chemical injection, a spare line and fiber-optic communications – all within a single cross-section. A 20-km umbilical will link the Troll A platform to Template W1, while a 7-km umbilical will then link Template W1 to Template W2. The contract also includes the supply of connections, terminations and other umbilical accessories.
Nexans offered Equinor a total “made in Norway” approach to the contract with the electrical and fiber optic elements manufactured at the Nexans Norway facility in Rognan, North Norway, while the complete umbilical system will be developed, manufactured and tested at Nexans Norway plant in Halden, Norway, the release said.
“Nexans has established an impressive track record in delivering umbilical projects for the Norwegian continental shelf and we look forward to continuing our long-standing relationship with Equinor by delivering this key contract for Troll Phase 3,” said Vincent Dessale, Nexans Senior Executive Vice President Subsea and Land Systems Business Group.
Nexans is scheduled to deliver the Troll Phase 3 umbilicals in the first quarter of 2020. First gas is expected from the project in the second quarter of 2021.
JDR Cable Systems reports that it has been awarded a contract by McDermott in the Persian Gulf for a project described as the world’s largest offshore oilfield.
A press release said that the contract for the project, owned and operated by Saudi Aramco, includes five thermoplastic umbilicals and hardware connecting new production platforms to the subsea valve skid (SSVS). The umbilicals, which range from 100 to 465 meters in length, will provide hydraulic and electric control to the SSVS.
The contract with McDermott is part of a larger program by Saudi Aramco to replace Safaniya’s aging facilities with electrified platforms to increase the efficiency and production of the field. The field is located 125 miles north of Dhahran in the Arabian Gulf and is estimated to contain 37 billion barrels of oil reserves.
“This is our fifth combined contract for the Safaniya field and truly demonstrates the quality and reliability of our products, said Chris Green, subsea production umbilicals sales manager at JDR, which was acquired last year by TFKable Group. He noted that speed of delivery was a key element of winning the order. The umbilicals will be manufactured at JDR’s plant in Littleport, U.K., with delivery scheduled for Q4 2018.
