The Sture terminal in the Municipality of Øygarden in Vestland is a major tanker port for crude oil.Oseberg Transportation System (OTS) is a comprehensive system that started up in 1988 for transport of Oseberg crude oil to the Sture terminal for further handling and offloading into crude oil tankers.
The processing plant at Kollsnes in Øygarden west of Bergen processes gas from the Troll, Kvitebjørn, Visund and Fram fields. The plant can process up to 156 million standard cubic metres (MSm3) of natural gas per day.
