Investigations are under way after two separate gas leaks occurred on Monday at Equinor’s mature Sleipner field offshore Norway.

Gas escaped from Equinor’s Sleipner A platform and there was a subsequent leak hours later on the Sleipner R riser platform at the same field.

Equinor confirmed the initial gas leak that occurred in a contained area related to a turbine on Sleipner A was quickly rectified.

However, during the process of resuming production and depressurisation, a further gas leak occurred the same day.

“Personnel on board mustered according to procedure in both situations, but they were demobilised shortly afterwards. No personnel were injured in any of the incidents,” Equinor said.

The Norwegian state-owned operator added that work is ongoing to safely resume normal operations.

“The authorities have been notified and the incidents will be further investigated to find the causal relation,” Equinor said.

The Sleipner field hosts four facilities: the Sleipner A processing, drilling and living quarters platform; the Sleipner riser platform for gas and condensate export; the Sleipner T processing and carbon dioxide removal platform and the Sleipner B unmanned production platform.

Sleipner T and Sleipner R are both connected permanently with a bridge to the Sleipner A platform.
