Global energy technology company SLB announced that its OneSubsea joint venture has been awarded an engineering, procurement and construction (EPC) contract by Equinor to upgrade the subsea compression system for the Gullfaks field in the Norwegian North Sea. The project will deliver two next-generation compressor modules to replace the units originally supplied in 2015 as part of the world's first multiphase subsea compression system.

Why it matters

The upgraded modules will increase differential pressure and flow capacity, enabling higher recovery and extended field life for the Gullfaks field. Subsea gas compression offers advantages over conventional topside solutions, including reduced energy consumption, more efficient use of topside facilities, and lower CO2 emissions over the system's lifetime.

The details

Under the contract, SLB OneSubsea will deliver two next-generation compressor modules to replace the units originally supplied in 2015 as part of the world's first multiphase subsea compression system. The upgraded modules will increase differential pressure and flow capacity, enhancing recovery and extending field life. Installation within the existing subsea infrastructure will minimize downtime and reduce overall campaign costs.

  • The original subsea compression system was supplied in 2015.
