WATCH: Aasta Hansteen Spar Takes Shape at HHI
Statoil-operated Aasta Hansteen field development, with a water depth of 1300 metres, is located in the Norwegian Sea, 300 km west of Bodø, Norway.
This pioneering development project awarded Technip, in a consortium with HHI, a contract to build the first Spar in Norwegian waters, and the largest ever built with a total hull length of 198 meters.
The following video is a timelapse documenting one of the Aasta Hansteen substructure blocks lifted to its final position at the Hyundai Heavy Industries (HHI) yard.
On November 19, weighing 2,200 tonnes and measuring 50X20X25 meters, the first of four modules was lifted into place using the yard’s new crane barge with a capacity of 10,000 tonnes.
When finished, the Spar will have a dry weight of 46 000 tonnes.
Aasta Hansteen Templates
Earlier this year, a new Norwegian depth record was set by EMAS AMC with the installation of three Aasta Hansteen subsea templates on the seabed, built at Aker Solution in Sandnessjøen.
The 138.5 meters long subsea construction vessel BOA Sub C was selected for the transport and installation of two 4-slot templates and one single-slot template.
Gas from the Aasta Hansteen discovery, made in 1997, will be exported through Polarled, a new 480-kilometre gas pipeline from Aasta Hansteen to Nyhamna in Møre og Romsdal county.
