DONG Energy has declared option for a second wind turbine Service Operation Vessel with Norwegian-based shipping company Østensjø Rederi requiring the construction of a newbuild vessel.

The newbuild will be sister vessel to the SOV awarded by Dong Energy last year and will function as a mother ship for wind turbine technicians servicing the Hornsea Project One wind farm located approximately 75 miles off England’s Yorkshire coast.

The 81.1-meter-long vessel will be a DP2 Service Operation Vessel with high station keeping capabilities, with 60 single cabins and accommodation for up to 40 wind turbine technicians and a crew of 20. The vessel will featured a motion compensated gangway system with an adjustable pedestal for safe operations and uptime. The vessel is also expected to be equipped with a helideck deck.

Delivery is anticipated for Q3 2018 from the shipbuilder Astilleros Gondan in Spain.

The Service Operation Vessels are designed by Rolls Royce in close cooperation with Østensjø Rederi. This will be the thirteenth vessel Østensjø Rederi builds at Astilleros Gondan, including three tugs and the one SOV already under construction.

“The new award is a further recognition of Østensjø efforts to expand our business into the renewable energy sector, following the strategy to diversify our operations. We are therefore very pleased that DONG Energy again has awarded us an exciting and important opportunity, says Kenneth Walland, CEO of Østensjø Rederi AS.

The contract with DONG Energy spans a firm period of five years with option for five more years.

The first SOV is scheduled for delivery in September 2017 and will service the Race Bank Offshore Wind Farm located in the North Sea about about 17 miles from the North Norfolk coast.
