The order which marks the second contract awarded by Volstad this year, is subject to board approval and financing, which is expected to be finalised during the second quarter of this year.
Built on the ST-259 CD design from Skipsteknisk in Ålesund, the vessel which will have a length of 125m and beam of 25m and is scheduled to be delivered in the fourth quarter of 2013.
Bergen Group Fosen CEO Arnar Utseth said the company has secured two new construction contracts from the same company within a period of two months.
"The former contract, signed in the first week in February this year, was also for a construction of an advanced OCV-vessel."
Since 2005, Volstad had ordered a total of eight vessels from Bergen Group Fosen, five of which have already been delivered.
Currently one vessel is being outfitted at Fosen and is scheduled to be delivered in summer this year.
In February this year, the company had secured a NOK800m ($140.90m) contract from Volstad to build a large offshore vessel.
The vessel will be 125m long and has a beam of 25m with delivery scheduled in the third quarter of 2013.
The vessel is similar to the design of the latest one and designed by Skipsteknisk in Aalesund with a type designation ST-259 CD.
Volstad is a privately owned Norwegian offshore shipping firm, which operates a fleet of vessels providing services for seismic operations, offshore construction, trenching and diving support.
Since the past five years, Bergen group had delivered a total of 16 advanced offshore vessels to different customers. The group’s shipbuilding division is expected to deliver four different vessels this year with a total contract value of NOK2.7bn ($475.56m).
