Brunvoll to Supply Propulsion for North Star’s New CSOVs

Brunvoll has entered into an agreement with VARD for the delivery of complete propulsion and maneuvering systems for two Commissioning Service Operation Vessels (CSOVs). The owner of these new vessels is North Star.

Each of the two CSOVs will be equipped, from aft to bow, with two azimuth propulsion thrusters, a retractable azimuth thruster, a tunnel thruster, and a combined retractable azimuth/tunnel thruster. Together with Brunvoll’s Propulsion and Thruster Control system, BruCon PTC, this will ensure efficient and capable vessels.

The azimuth propulsion thrusters are equipped with Brunvoll’s latest energy-efficiency technology, theDL1-nozzle, also known as the “Dragless." While traditional nozzles experience an efficiency drop at transit speeds, the DL1 maintains favorable hydrodynamic characteristics across a broader operating range.

The vessels are based on VARD’s 4 19 design, with the following main particulars: length of 87.5 meters, beam of 19.5 meters, and accommodation capacity for 120 persons, along with all equipment required for a CSOV. 

North Star has secured a long-term charter agreement with RWE for both vessels, which are scheduled for delivery in 2028 and 2029.
