Five pulls with a mixed 150,000 horse power have actually begun the 500 maritime mile tow-out of the titan Aasta Hansteen spar system from Stord, Norway to the Aasta Hansteen area in the Norwegian Sea.

Located in around 1,300 meters of water and also 300 kilometres from land, the Aasta Hansteen gas area is being created with a Spar FPSO system that will certainly be the very first on the Norwegian Continental Shelf and also biggest worldwide.

A spar is a drifting setup including an upright round hull that is tied to the seabed.

The separation of the Aasta Hansteen system is the greatest tow-out procedure because the Troll A system was relocated offshore in 1996. The trip, which is anticipated to take 12 days, is being handled by Subsea 7 and also entails the pulls Skandi Vega, Skandi Iceman, Normand Ranger, Normand Prosper and also Siem Opal.

The Aasta Hansteen exploration was made in 1997 and also in fact makes up 3 different explorations; Luva, Haklang and also Snefrid South, with recoverable gets approximated at 51 billion typical cubic meters of gas.

The area is identified by its remote area much from land and also well established facilities, in addition to its considerable water deepness and also difficult weather.

The spar setup itself includes standard topsides with handling centers. Pure steel risers will certainly deliver the gas from the seabed to the system and also forward to coast through the brand-new 480 kilometres Polarled gas pipe. The hull will certainly be geared up with storage space for condensate which will certainly be filled onto shuttle bus vessels at the area.
