Kongsberg Maritime will supply a propulsion system for the new CSOVs


Kongsberg Maritime has been contracted to supply the propulsion technology for two new Commissioning Service Operations Vessels (CSOVs) being built by VARD for new vessel owner company Norwind Offshore.


Propulsion technology, which for the CSOVs will include new permanent magnet (PM) PMAZ 2600PM azimuth thrusters, PM tunnel thrusters and a retractable azimuth thruster.

These units are part of a range of environmentally focused propulsion units developed by KONGSBERG over the last decade, all based on the company’s in-house PM technology. According to KONGSBERG, with only one rotating component in the underwater unit, low oil volume and no requirement for lubrication pumps or internal cooling systems, PM thrusters experience reduced wear. KONGSBERG also claims that they also benefit from significant reductions in power consumption, emissions and oil spill risks compared to conventional azimuth thrusters, and are designed to meet stringent noise and vibration requirements. , both on board the ship and with respect to emissions at sea (URN).



“We are investing in this cutting-edge technology from KONGSBERG with confidence that it will pay off in the long term,”
said Svein Leon Aure, CEO of Norwind Offshore. “Our operational expenses will be significantly reduced compared to using conventional thrusters, and so will our environmental footprint. This provides us with purpose-built vessels for the future of advanced marine operations in the wind market. offshore.



“It is a pleasure for us to know that our high-end products play such a central role in the contract of this new innovative player in the offshore wind market”,
adds Ottar Ristesund, SVP Sales Propulsion & Engines, Kongsberg Maritime. “We share our goals for enabling safer, more economical and more environmentally friendly offshore operations with VARD and Norwind Offshore, and it will be rewarding for all concerned to put these principles into practice in such a direct and practical way.”

The two new buildings are of VARD 4 19 design, developed by Vard Design in Ålesund, Norway. CSOVs are tailor-made for global services and maintenance operations at offshore wind farms.

The first vessel will be fitted out and delivered by VARD in Norway in the second quarter of 2023, with the hull to be built in Vard Braila in Romania. The second vessel will be built and delivered by Vard Vung Tau in Vietnam, with delivery scheduled for the third quarter of 2024.

A third ship will follow these new constructions; one of VARD’s Platform Supply Vessels (PSV) which will be converted into a Service Operation Vessel (SOV). The vessel has been in operation in Asia and Australia, and will now sail to Vard Brattvaag in Norway for major conversion and outfitting. The vessel will be delivered to Norwind Offshore in the second quarter of 2022.

Norwind Offshore is a newly established ship-owning company, formed by Farstad, Volstad and Kleven and based in Ålesund, Norway, offering specialist vessels designed for advanced marine operations in the development and service of the offshore wind sector.
