Brunvoll Propulsion and Manoeuvring System for Cyan Renewables new SOV

Brunvoll has signed a contract with VARD for the delivery of a comprehensive propulsion and manoeuvring system for Cyan Renewables new Service Operation Vessel (SOV). The vessel will have the first azimuth propulsion thrusters from Brunvoll with an 8-degree tilted propeller and nozzle, for enhanced performance during dynamic positioning operations.

The delivery for the new SOV consists of two azimuth propulsion thrusters, two retractable azimuth thrusters, a tunnel thruster, and Bruvoll’s Propulsion and Thruster control system, BruCon PTC.

The azimuth propulsion thrusters will be the first deliveries from Brunvoll with an 8-degree tilted propeller and nozzle. The tilted propeller contributes to increased efficiency in terms of reduced thruster and hull interaction, known as the Koanda effect. It also reduces the dead zones for the azimuth thruster, where the propeller wake normally interacts with the skeg or other thrusters on the vessel.
“Brunvoll is proud to partner with VARD and Cyan, and it’s a pleasure to welcome Cyan, as Asia’s first dedicated offshore wind vessel owner, as a customer of Brunvoll. We would also like to thank VARD for once again returning to Brunvoll with new and exciting projects and opportunities.”, says Bernt Rune Riksfjord, VP Sales at Brunvoll.

The VARD designed vessel will be built at VARD’s shipyard in Vung Tau in Vietnam. The vessel will become 85.5 meters of length, a breadth of 19.5 meters, and be able to accommodate 83 crew members and wind technicians. The vessel is schedules to be delivered in Q2 2026 and will enter into operation for Siemens Gamesa at the Hai Long Offshore wind farm in Taiwan.
