Aker Solutions to design Norwegian Sea spar

By OGJ editors

Statoil SA has let contract to Aker Solutions for front-end engineering and design of a novel spar platform for Luva gas and condensate field in the Norwegian Sea, which has been renamed Aasta Hansteen.

Aker Solutions says the structure, called a belly spar, will be the world’s largest spar platform, the world’s first with condensate storage capacity, and the first spar offshore Norway.

It will have a hull length of 193 m and a draft of 170 m. It also will be the first production platform on the Norwegian continental shelf with steel catenary risers, according to Henning Ostvig, head of front-end and technology at Aker Solutions.

The spar will be moored in 1,300 m of water with a set of polyester lines, housing accommodation facilities and processing equipment to handle production from wells completed subsea (OGJ Online, Jan. 30, 2012).
