Kollsnes is a natural gas processing plant operated by Equinor on the southern part of the island of Oøy in Øygarden Municipality in Vestland county, Norway.
Kollsnes has a capacity of 143,000,000 cubic metres (3.8×1010 US gal) of natural gas per day.
The dry gas is compressed and then shoved by large compressors out in the pipe systems that transport it to the customers.
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 Equinor.
