Description

• Heimdal is a gas field located in the central part of the North Sea. The water depth in the area is 120 metres. The field has been developed with an integrated drilling, production and accommodation facility with a steel jacket (HMP1).
• Heimdal is now mainly a processing centre for other fields. Huldra, Skirne and Vale deliver gas to Heimdal.
• In addition, gas from Oseberg is transported via Heimdal.
• Originally, gas from Heimdal was sent in Statpipe to Kårstø and on to the Continent, but can now also be sent in Vesterled to St Fergus in the United Kingdom.
• After Heimdal Gas centre was established, a new gas pipeline was connected to the existing gas pipeline from Frigg to St Fergus.
• A gas pipeline has also been laid from Heimdal to Grane for gas injection.
• Condensate is transported by pipeline to Brae in the British sector.
