Equinor Starts Hook-up Work at Johan Castberg Oilfield


313-Meter-Long FPSO Vessel Securely Anchored at Barents Sea Site



Equinor’s floating production, storage and offloading (FPSO) vessel has successfully anchored at the Johan Castberg oilfield, as the Norwegian operator prepares for production start-up at the Barents Sea site by year-end.

The hook-up of the 313-meter-long FPSO to subsea facilities would now begin, Equinor said.

Equinor has a 50% stake in the field, with partners Vår Energi and Petoro holding 30% and 20%, respectively.

“Johan Castberg is important for our development plans in Northern Norway,” said Grete Birgitte Haaland, Equinor’s senior vice president for Exploration & Production North.

“When the field comes on stream, a new province will be opened for oil recovery in the Barents Sea. This provides new opportunities for the exploration for and development of new discoveries in the area. Working with our partners we are already maturing five discoveries towards a possible tie-in to Johan Castberg.”

Johan Castberg, located 240 kilometers northwest of Hammerfest, is a large oil field with estimated recoverable volumes of between 450 and 650 million barrels.

The field is expected to produce for 30 years, and at its peak, could produce some 220,000 barrels per day. The field development concept includes 30 wells distributed across ten subsea templates and two satellites that will be tied back to the FPSO. To date, 13 of those wells have been drilled, with drilling operations set to continue into 2026.
