Oil giant BP has halted production at its Skarv field in the Norwegian Sea due to a technical issue.
The company has invested more than £4billion in the development since production began in January last year.
A spokesman for BP said a problem with a short-circuit resulted in the outage of a train 1 gas compressor.
As a result, both gas and condensate production was shut down.
The spokesman said: “All the safety systems functioned according to plan and no one was injured.
“It is being assessed whether the transformer needs to be changed out or repaired.
“We do not expect any production of gas and condensate this week.
“The oil production has been shut in since September 8th due to a problem with riser valve for gas injection – work is ongoing and production start is expected during this month.”
The field’s floating production, storage and offloading vessel produced around 70,000 barrels of oil per day in August.
Skarv is operated by BP with 23.84%, with partners Statoil holding a 36.17% share, E.ON E&P, 28.08% and PGNiG , 11.92%.
The field is part of BP’s multi-billion pound investment programme in the North Sea.
Four major developments are under way in the UK – Clair Ridge, Quad 204 (Schiehallion), Devenick and Kinnoull – plus the Valhall redevelopment in Norway.
