700 shipyard workers have devoted two and a half years to building a separate gas treatment unit for Dvalin. The module was built at the Aibel yard in Haugesund on assignment for Equinor, the owner of the Heidrun platform.

An impressive 3.5 million working hours have been logged on the Dvalin project without a single serious personal injury.
