Statoil shut down production at the Statfjord A platform on Sunday after a fire broke out at the offshore Norway facility.
Statoil said the fire started in a loading pump in the platform’s utility shaft.
No injuries or environmental impacts have been reported.
Statoil said 67 people were on board the platform when the incident occurred.
The blaze was restricted to one area that is separated by fire barriers, Statoil said.
The company’s automatic deluge system was triggered when smoke was detected.
The company’s emergency response organization on Statfjord A extinguished the fire on Sunday.
The area is now being monitored by the fireguard.
As of 10 a.m. on Sunday, 20 people had been moved to the Statfjord B platform by SAR helicopter.
Crew members on board the Statfjord A platform without emergency response assignments were sent to lifeboats.
“They are now being gathered for a debriefing on the platform,” Statoil said.
Statoil’s emergency response organizations at Sandsli and in Stavanger were mobilized during the incident.
Statoil said two SAR helicopters are at the Statfjord A field and the emergency response vessel Stril Herkules is also in the area.
Statfjord A is a production platform that has a concrete substructure and storage cells.
The Norwegian part of the Statfjord field is located in blocks 33/9 and 33/12 in license 037 and contains both oil and gas.
