Nexans will play a vital role in the Troll Phase 3 project by supplying Equinor with the complex umbilicals required to power and control the subsea systems.
July, 2018
The Troll oil and gas field is the most prolific field on the Norwegian continental shelf (NCS), with more than half of its reserves still remaining after over 20 years of production. The initial development was carried out over two phases, and now Equinor is starting the Phase 3 development to recover the large amount of gas resources in the western part of the field. Nexans will play a vital role in the Troll Phase 3 project by supplying Equinor with the complex umbilicals required to power and control the subsea systems.
For the Troll Phase 3 development 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 kilometer umbilical will link the Troll A platform to Template W1, while a 7 kilometer 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.
