North Star Group has secured a long-term charter contract to deliver an additional ship as part of its new hybrid-powered renewables fleet to support the third phase of the Dogger Bank Wind Farm in the North Sea.

The service operation vessel (SOV) will be of Vard 4 12 design, the fourth that Vard has supplied for North Star. The Dogger Bank Wind Farm, 130km off the north-east coast of England, is currently under construction by SSE Renewables, Equinor and Eni. When complete it will be the world’s largest offshore wind farm.
