Kvaerner starts the next phase of work at Aasta Hansteen in Digernessundet

Aasta Hansteen was towed to Digernessundet where Kvaerner since June has assisted with the completion of the cylindrical substructure (spar) and preparation for hook-up with the topside.

On Saturday the topside for Aasta Hansteen was towed to Digernessundet where Kvaerner since June has assisted with the completion of the cylindrical substructure (spar) and preparation for hook-up with the topside. After the topside and spar have been hooked up, Kvaerner will continue the work on completion while the platform is anchored in Digernessundet outside Stord.

"We have had close and good cooperation with Statoil and TechnipFMC during the preparations, and look forward to continuing the work of completing the world's largest spar platform," says Hans Bruntveit, project manager in Kvaerner.Completion work will continue until the spring of 2018 when the spar platform is being towed out to the field in the Norwegian Sea, about 320 kilometers west of Bodø. Kvaerner will also assist Statoil with offshore hook-up and preparations for production.

Kvaerner will work round-the-clock with completion of the platform until it is towed out. The work to be carried out at Stord will mainly consist of installation of pumps and riser caissons, connection of systems, welding of connection between spar and topside, and removal of temporary structures.

Statoil is the operator of Aasta Hansteen the first spar platform on the Norwegian continental shelf and the largest in the world. The cylindrical substructure will be floating160 meters below the surface and be anchored with fiber rope and chain fastened to anchors on the seabed at around 1 260 meters water dept in the Norwegian Sea.
