A fire broke out on June 21 at Equinor's Gina Krog oil platform in the North Sea, halting output, a company spokesperson said.

"We had a fire in an electric closet in the living quarters of the platform this morning. It was reported and extinguished. Production is shut down," said the spokesperson, adding it was as yet unclear when output would restart.

Of the 64 people on board at the time of the incident, no one had symptoms of having been exposed to smoke.

The Equinor spokesperson declined to comment on the level of output at the field when the fire occurred.

Gina Krog produced 726,000 standard cubic meters of gas and 5.5 MMbbl of oil in 2021, according to official data.

Equinor operates the field and has a 59% stake in it, while KUFPEC of Kuwait has 30% and Poland's PGNiG has 11%.
