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 , with operations starting on 1 October 2004. Starting in October 2005, the gas from Visund is also landed at Kollsnes. With a capacity of gas per day and large flexibility, the new NGL plant can process gas from new fields that would be built.
