The mating of the spar’s topside and hull was completed in December 2017. Equinor and its partners started production on 16 December from the Aasta Hansteen gas field in the Norwegian Sea. Gas from the field was available on 17 December to the market, opening a new region for gas export to Europe and the UK via the Polarled pipeline to the Nyhamma gas processing facility. It is also the first spar in Norway and the first in the world to contain condensate storage, with storage capacity of 25 000 m3. The area is characterized by particularly harsh environmental conditions.
