DONG Energy has declared option for a second SOV for a period of five years firm and five optional years. The 81,10 m long vessel, with a beam of 17,0 m will be a sister vessel of the SOV awarded by DONG Energy in October last year and will function as a mother ship for wind turbine technicians as they perform maintenance work on the Hornsea Project One wind farm. The second vessel will be delivered in Q3/2018.

The vessel is a DP2 Service Operation Vessel with high station keeping capacities. 60 single cabins of high standard can accommodate up to 40 wind turbine technicians in addition to a marine crew of 20. A motion compensated gangway system with an adjustable pedestal will be installed to ensure safe operations and optimal uptime. Special areas and functions of the vessel are made in accordance with the charterer`s requirements. The vessel is expected to be equipped with a helideck deck.

The Service Operation Vessels are designed by Rolls Royce in close cooperation with Østensjø Rederi. Astilleros Gondan in Spain will again be the builder of the vessel. This will be the 13th vessel Østensjø Rederi builds at Astilleros Gondan and they are presently building three tugs to Østensjø Rederi in addition to the two SOVs.

“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.
