The situation is returning to normal and external resources from the emergency services have been demobilised.
It is too early to say anything about the cause of the incident, which will be investigated.
The leak occurred on the Statpipe section leading into the plant. Both Statpipe production trains have been stopped.
The incident did not lead to any physical injuries.
During normalisation and start-up of the plant following the incident last night, a smaller leak occurred, which is not usual during run-up of plant sections. The leak has been identified and is under control. The situation did not involve mobilisation of external resources.
About the plant
The Kårstø processing plant north of Stavanger plays a key role in the transport and treatment of gas and condensate (light oil) from important areas on the Norwegian continental shelf.
First gas arrived at the plant on 25 June 1985, and dry gas began to be dispatched by pipeline to Emden in Germany on 15 October of the same year. The Statpipe trunkline system carries gas from the North Sea to Kårstø.
