Kongsberg Maritime to deliver propulsion system for newbuild CSOVs

Kongsberg Maritime has been commissioned to deliver propulsion technology for two new Commissioning Service Operations Vessels (CSOVs) being built by VARD for new ship-owning company Norwind Offshore.

The 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 an environmentally focused range of 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 inboard cooling systems, PM thrusters experience reduced wear and tear. KONGSBERG also claims they also benefit from significant reductions in energy consumption, emissions and oil spill risk when compared with conventional azimuth thrusters, and are designed to meet stringent noise and vibration requirements, both on board the vessel and regarding emissions to sea (URN).

"We are investing in this state-of-the-art technology from KONGSBERG in full confidence that it will pay off in the long term,”
said Svein Leon Aure, CEO of Norwind Offshore. “Our operational expenditures will be considerably reduced in comparison to using conventional thrusters, and the same goes for our environmental footprint. This provides us with purpose-built vessels, designed for the future of advanced maritime operations in the offshore wind market.”

“It’s a pleasure for us to know that our high-end products perform such a central role in the contract for this new and innovative player in the offshore wind market,”
adds Ottar Ristesund, SVP Sales Propulsion & Engines, Kongsberg Maritime. “We share our objectives to enable safer, more economical and greener operations at sea with both VARD and Norwind Offshore, and it will be rewarding for everyone concerned to put these principles into practice in such a direct and practical way.”

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

The first vessel will be outfitted and delivered from VARD in Norway in Q2 2023, with the hull to be built at Vard Braila in Romania. The second vessel will be built and delivered by Vard Vung Tau in Vietnam, scheduled for delivery in Q3 2024.

A third vessel will follow these newbuilds; one of VARD’s Platform Supply Vessels (PSV) that will be converted to 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 an extensive conversion and outfitting. The vessel will be delivered to Norwind Offshore in Q2 2022.

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