Production had to be halted temporarily from the Knarr oil field in the Norwegian North Sea after a small fire broke out.
The incident on the floating production, storage and offloading vessel (FPSO) happened just over a week after production began.
The small fire broke out during the night, Norway’s Joint Rescue Coordination Centre said.
Operator BG Group holds a 45% stake in the field while Idemitsu holds 25%, Wintershall holds 20% and DEA 10%.
