SLB OneSubsea, a joint venture backed by SLB, Aker Solutions, and Subsea7, has been awarded an engineering, procurement and construction contract by Equinor to upgrade the subsea compression system for the Gullfaks field in the Norwegian part of the North Sea.
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 minimise downtime and reduce overall campaign costs.
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.
“By upgrading the existing subsea compression system with next-generation technology, we are supporting Equinor’s long-term recovery strategy for Gullfaks with a more efficient solution to help unlock additional capacity and maximise field recovery,” said Andreas Fjellbirkeland, VP of processing systems at SLB OneSubsea.
“Join the companies that smart energy professionals follow – because when you’re featured on OGV, the industry pays attention.”
