North Star has once again entrusted Brunvoll to equip its next two commissioning service and operation vessels(CSOVs), currently under construction by VARD shipyard. The vessels will be deployed in offshore wind energy projects, and will feature propulsion and maneuvering systems fully supplied by the Norwegian manufacturer.
New maneuvering systems on North Star’s vessels
Each vessel will be equipped with an integration of fixed and retractable azimuth thrusters, tunnel thrusters and a combined azimuth/tunnel unit. Such a configuration will provide maximum maneuvering efficiency and precision, even in highly demanding sea conditions. In addition, the BruCon PTC control system, a technology developed by Brunvoll to optimize the performance of automated navigation, will be integrated.
Dragless technology, integrated into Brunvoll’s DL1 nozzle, improves the vessel’s hydrodynamic behavior at different speeds and reduces loss of efficiency in transit, a common problem with traditional nozzles.
The vessels will be 87.5 meters long and will be able to accommodate up to 120 people. They are scheduled for delivery in 2028 and 2029, with charter contracts signed with RWEa global operator of offshore wind farms. With this new partnership, North Star reaffirms its transition towards a more sustainable operating model, integrating hybrid technology and offshore logistics support solutions.
Both VARD and Brunvoll have worked closely with North Star in previous design and technical integration phases. The use of a complete propulsion package from a single supplier reduces operational complexity and improves interoperability between onboard systems, a strategic aspect to ensure reliability during extended offshore operations.
