ENGIE E&P’s Gjøa-platform in the North Sea is back in production after the gas leak on 21 June. This follows extensive inspection and start-up work.
Gjøa will gradually increase production back to its normal level shortly after start-up.
The direct cause of the leak was a crack in a weld of a ½” pipe associated with a condensate pump. Inspections have revealed welding deficiencies in the pump where the leak occurred and in six other condensate pumps. This issue has now been addressed and the pumps are back in service.
In connection with the shutdown caused by the leak, we identified incorrect functioning on some valves in the emergency shutdown system. These malfunctions have now been rectified.
The incident is currently being investigated both internally and by the Norwegian Petroleum Safety Authorities.
Daily oil and gas production of Gjøa and Vega is about 30 000 barrels and 19 MSm³ respectively.
