A leak in a valve in the gas injection system
Norway: Monday evening there was a leak in a valve in the gas injection system on the Oseberg Field Center.
All safety and emergency systems functioned satisfactorily. Production was closed down and the personnel on board assembled.
The leakage has occurred during the run-up of the processing plant on the Center following Saturday's closure, which was due to an oil and gas leakage.
?Monday?s leakage occurred when we reduced the pressure and temperature of the plant after the stoppage. It's at just such times that this can happen," says Oseberg Field Center platform manager Vidar Nygеrd Karlsen, who adds that great effort is always taken to look for such leakages during the re-start phase of the processing plant.
Following Saturday's and Monday's leakages, all personnel were assembled on board in the cinema to be briefed about the incident.
Production on the Oseberg field has been closed down while the valve insert is replaced, while Oseberg East and Oseberg South are producing at a reduced rate.
Repair work on the insert is being carried out now. It is expected that production on the Oseberg field can be started up again in the course of the next 24 hours.
