Operation
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.
