Service Operation Vessel (SOV) for North Star.

DJI 0062 HDR

This SOV is the second of four purpose designed and built ships destined for decade-long minimum charters to support operations and maintenance (O&M) work at the Dogger Bank offshore wind farm.
The vessel is based on the Vard 4 19 hull design and has been developed with North Star specifically to handle planned maintenance on the Dogger Bank A, B and C sites and tailored for effective and efficient operations in the harsh North Sea environment more than 130 kilometers off the north-east coast of England.

For optimal efficiency, the vessel utilizes a cutting-edge diesel-electric propulsion system, bolstered by a battery hybrid power management and architecture. It incorporates the highly efficient Voith eVSP propulsion and a drop-down azimuth thruster for field efficiency. Additionally, the vessel benefits from the comprehensive SeaQ power package delivered by Vard Electro, providing complete control over the onboard power systems. This integration allows for reduced fuel consumption, minimized emissions, improved responsiveness, and enhanced safety.
