    Kollsnes Gas TERMINAL   

    Kollsnes Gas Process Plant in Øygarden Municipality north-east of Bergen, was set in operation in 1996 as a part of the Troll Project. At the plant, gas from the Troll, Kvitebjørn og Visund fields in the North Sea are processed, with a capacity of 145 Sm3 NGL – natural gas liquids and 69 000 Sm3 condensate per day.

    Shore approach of the Troll gas pipelines

    An important civil work at Kollsnes was the Shore Approach of the Troll Gas pipeline as s shown on the figure below. The work was executed from January 1991 to December1995, and comprised 7500m tunnels to a connection point for the Troll pipelines 3600 m from landside and 200 m under sea level.


    Kollsnes Gas Terminal – Shore approach

    The contract included also engineering and the installation of two 450 tons riser packets. These riser packets were installed and concreted into the piercing shafts from the tunnel system at 168.5 m below sea level. Piercing of a tunnel/shaft system into sea at 168.5 m is one of the deepest ever executed in the world.

    The Sture Oil Terminal

    At the Sture Terminal in Øygarden municipality, approximately 60 km north-east of Bergen, the construction work started in 1984 with Norsk Hydro as operator.

    The Sture Terminal was able to receive the first oil brought ashore from the Norwegian Continental Shelf in December 1988. This was the first crossing with a pipeline of the Norwegian Trench down to a water depth of 360 m. 

    The terminal was officially opened by King Olav at 30 March 1989. The Sture Terminal receives crude oil and condensate through the Oseberg Transport System (OTS) from the Oseberg A platform, via a 115 km long 28” (71.1cm) pipeline, and crude oil from the Grane field through Grane Oil Pipe (GOP) via a 212 km long pipeline 29” (74.0 cm). The terminal comprises two large quay facilities able to accommodate handling of large crude carriers up to 300 000 dead weight tons.

    There are five crude oil caverns of dimensions (length*width*height of 314*19*33 m) with storage capacity of 1 million m3.


    Lunch at the Coastal Museum at Ovågen, Øygarden.

    The excursion will end with a cruise to the islands north of Øygarden, before returning to Bergen.
