Norwegian oil company StatoilHydro ASA says it has halted oil and gas production on a North Sea platform after a fire broke out.

The operator says the fire was soon extinguished on the Oseberg A platform on Sunday afternoon and there was no need to evacuate personnel. The rig is situated 80 miles northwest of the port city of Bergen on Norway’s western coast.

It was not immediately clear what caused the fire.

Last year, the platform produced some 90,000 barrels a day. It was not clear when production could begin again.
