The contract comprises project management, engineering, procurement, construction, and installation of about 100 km (62 mi) of rigid pipelines, including 40 km (25 mi) of pipe-in-pipe flowlines, 27 km (17 mi) of water injection, and 37 km (23 mi) of gas injection pipelines.
The marine operations scope includes the installation of 23 km (14 mi) of umbilicals, tie-in spools, and pre-commissioning.
Project management and engineering will start immediately at Subsea 7’s offices in Stavanger, Norway. Fabrication will take place at its spoolbase in Vigra, Norway, and offshore operations will be carried out in 2021.
According to Equinor, this will increase the share of contracts awarded to Norwegian suppliers in Phase 2 to 85%.
The first phase of the Johan Sverdrup development is nearly 90% completed, with production expected to start in November, Equinor said.
In Phase 1, Subsea 7 was responsible for delivery and installation of several subsea components and tie-in of pipelines at the field.
