The sail away date for the substructure of the world’s largest Spar platform, Aasta Hansteen, is approaching.

Soon it will leave Hyundai Heavy Industries in South Korea and the massive 46,000-tonne structure will be transported to Norway on the world’s largest heavy transport vessel, Dockwise Vanguard.

Once it arrives on site it will be partially submerged by filling ballast tanks to 177 m and anchored to the seabed. This will leave only the top 21m above the surface.

Its seabed moorings will be constructed of cut resistant polyester and steel chain.

The finished platform will come in at a height of 198m (of which 177m will be submerged) and diameter of 50m making it the largest spar platform hull ever buil.

Its hull will be a Truss Spar type allowing condensate to be stored in the hull beneath sea level and offloaded to a shuttle tanker.
