VARD wins new North Star contract for an additional SOV to operate on Dogger Bank Wind Farm

Designer and shipbuilder of specialised vessels VARD has secured a new contract for the design and construction of a Service Operation Vessel (SOV) for North Star Group in the UK, to support the third phase of Dogger Bank Wind Farm in the North Sea.

The vessel of VARD 4 12 design will be the fourth SOV to be delivered from VARD to North Star for operation on Dogger Bank. The vessel will be built and delivered by VARD, scheduled for delivery to North Star in Q4 2024.

Dogger Bank is currently under construction by joint-venture partners SSE Renewables, Equinor and Eni and when completed will be the world’s largest offshore wind farm.

“Securing the final SOV contract required for the Dogger Bank Wind Farm development for at least the next decade is fantastic news” said North Star CEO Matthew Gordon. “Together with VARD, we have designed a sustainable renewables fleet that elevates SOVs into a new era of comfort, safety, reliability, and workability. The technology onboard includes low fuel consumption, digital decision support technology, advanced propulsion systems, hybrid power management and a waste heat recovery system. Coupled with the well-planned recreation and accommodation areas, they will provide a superior home-from-home living space for the offshore wind technicians working offshore. We look forward to a successful build with VARD and delivering these next generation vessels on schedule.”

The VARD 4 12 design is developed by Vard Design in Ålesund. The SOV for North Star has been developed to handle corrective maintenance services on the Dogger Bank C wind arrays, in the harsh North Sea environment more than 130 kilometres off the north-east coast of England. The vessel is tailored to meet the North Star’s expectations for optimal standards of workability, comfort, safety, and sustainability.

In the development phase, it has been a high focus on the vessel’s environmental footprint and operability, to include a hybrid battery solution and prepare for carbon-neutral operations. Another key design element has been to ensure efficient logistics. The vessel will have a height-adjustable, motion-compensated gangway with elevator system, a height-adjustable boat transfer system, as well as a 3D-compensated crane for cargo transfer.

The new SOV will be 78 metres in length with a beam of 19 metres and have an accommodation for 60 persons in single cabins.

For optimal efficiency, the hybrid vessel will be equipped with a diesel-electric propulsion system, highly efficient main propellers, and tunnel thrusters with permanent magnet electric motors in combination with SeaQ solutions supplied by Vard Electro in Norway.

The SOV will feature a fully integrated SeaQ Energy Storage System Solution in combination with SeaQ Integrated Automation System (IAS), SeaQ Power Management system (PMS), SeaQ Energy Management System (EMS), and SeaQ Green Pilot (energy monitoring system) for improved operational performance and reduced environmental footprint. The set-up makes it possible to reduce fuel consumption and emissions, in addition to enhance responsiveness and safety.

The SOV is scheduled for delivery from VARD’s shipyard Vard Vung Tau in Vietnam in 2024. The shipyard has a broad portfolio of vessels for the offshore and renewables market.
