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.
