Video – Arctic Platform Aasta Hansteen Closer To Production

Published at 07:18PM - 29/01/16

Statoil’s offshore arctic Spar platform, Aasta Hansteen, moves closer to production with the delivery of the asset’s accommodation module.

The module was fabricated and finished in The Netherlands before being transported to the main Topside fabrication yard in Korea by the Dockwise Swan heavy lift semisubmersible vessel.

Once complete the Aasta Hansteen will be installed above the arctic circle in the Norwegian Sea, approximately 186 miles (300km) due west of the Norwegian town of Bodø.


Statoil continue to remain quiet over the platform’s installation and startup dates due to a string of delays from the fabrication yard Hyundai Heavy Industries in South Korea; however this is expected late 2017 with first gas in early 2018.

The gas field’s development has required a growing investment currently standing at approximately  NOK 57 billion (US$6.5bn); whilst holds has estimated recoverable reserves of 47 billion standard cubic meters of gas.

Aasta Hansteen Spar

The Aasta Hansteen is of spar design with a diameter of 50 metres (164ft) and a hight of 198 metres (650ft)- of which 177 metres (581ft) will be submerged.

Aasta Hansteen will sit in a water depth of 1,300 metres (4265ft), whilst its size and displacement will make it the largest Spar platform ever built.

Polarled Pipeline

The project has also involved running a 300 mile (482.4km) long subsea pipeline known as the Polarled Pipeline to linkup the Aasta Hansteen Spar with the Norwegian mainland; that was completed back in September 2015 by the world’s biggest pipelay vessel- the Allseas Solitaire.
