Oil giant Statoil – soon to be Equinor – outline the journey that the Aasta Hansteen topside will take as the giant SPAR platform is towed out to the Stord field.
In Ølensvåg the topside will be transferred to two new vessels that will take it to Stord to be mated with the substructure, creating the world’s largest spar-platform.
The Aasta Hansteen discovery was made in 1997 and actually comprises three separate discoveries; Luva, Haklang and Snefrid South, with recoverable reserves estimated at 47 billion standard cubic metres (Sm3) of gas.
The drilling campaign on Aasta Hansteen is planned to start towards the end of 2017 or the beginning of 2018.
The gas field is being developed with a Spar FPSO platform, as the first on the Norwegian Continental Shelf and the largest in the world. Spar is a floating installation consisting of a vertical cylindrical hull moored to the seabed.
