Kollsnes is a natural gas processing plant owned and operated by Statoil on the southern part of the island Oøy in Øygarden, Norway. It processes the natural gas from the gass fields Troll, Kvitebjørn and Visund with a capacity of 143 million standard cubic meters of natural gas per day.
At Kollsnes the Natural gas liquids (NGL) are separated out of the gas. The dry gas is compressed and then shoved by large compressors out in the pipe systems that transport it to the customers. In 1999 it was decided that the gas from Kvitebjørn was to be landed at Kollsnes. The consistency of the gas from the field made it well suited to be reprocessed to upgraded products. The new plant that was built cost NOK three billion, with operations starting on October 1, 2004. From October 2005 the gas from Visund is also landed at Kollsnes. With a capacity of 25 million Sm3 gas per day and large flexibility, the new NGL plant can process gas from new fields that would be built.
Though the Vestprosess gas pipe the plant at Kollsnes is linked to the plants at Mongstad, where the NGL from Kollsnes is fractioned into propane, butane and naphtha. The gas from Kollsnes is transported through the four pipe systems Statpipe, Zeepipe, Europipe I and Franpipe to continental Europe and supplies Austria, Belgium, France, Germany, the Netherlands, Spain and the Czech Republic with gas. The pipes are owned by Gassled, operated by Gassco while the technical responsibility is handled by Statoil.
