Åsgard B hull en route to Norway
The hull of the semi-submersible Åsgard B gas and condensate platform has left the Daewoo yard in South Korea, bound for Norway.
The hull measures 115 by 96 metres and weighs 19,000 tonnes. Heavy-lift carrier Mighty Servant 3 will transport the hull to Norway from the Daewoo Heavy Industries' yard near the South Korean town of Pusan.
The sea journey is expected to take about 45 days, according to Rolf Olavesen, public affairs manager at Kværner Oil & Gas.
The itinerary leads south-westwards through the Strait of Malacca, across the Indian Ocean, through the Suez Canal and the Strait of Gibraltar and then up the English Channel towards the North Sea and Norway. The hull is expected to arrive in Stavanger by the beginning of September.
According to Mr Olavesen, the hull will be positioned diagonally on the vessel and the breadth of the cargo will be almost 150 metres. Calculations have included the wind load and centre of gravity during transport. Passing through the Suez Canal will be a critical point with small margins, as the canal is only about 150 metres wide.
When the Åsgard B hull reaches Stavanger, preparations will first be made by Aker Marine Contractors at Jåttavågen for the mating of topsides and hull. The hull will then be transported to the Kværner Oil & Gas yard at nearby Rosenberg where two topsides weighing a total of 33,000 tonnes will be welded together before being mated with the hull.
Mr Olavesen says that this operation will take place in the Åmøy fjord close to Stavanger in October.
