VARD has signed a contract for the design and construction of two Commissioning Service Operation Vessels (CSOVs) for UK-based Purus Wind. The agreement also has an option for two additional vessels.

The two CSOVs, developed by Vard Design in Ålesund, Norway, are of VARD 4 19 design. In collaboration with Purus Wind, the design been tailored and upgraded to give environmental benefits with a hull design optimized for low fuel consumption and resistance, in addition to high operability and comfort.

The battery hybrid system allows the vessels to run with zero emissions for periods of time. The vessels are prepared for charging at sea, allowing them to be connected to the power grid in harbours or wind farms to charge regularly, without having to go ashore.

The CSOVs are a highly versatile platform for all wind support operations, focussing on superior operability, large storage capacities, onboard logistics and comfort. The design is also prepared for future operation on methanol, providing an additional sustainable option to the operation. The length of the vessels is approximately 87 metres, with a beam of about 19.5 metres. The maximum transit speed is 13 knots, and the vessels each have 85 cabins for 120 persons on board.

The vessels are to be equipped with VARD daughter SEAONICS' Electric Controlled Motion Compensated (ECMC) crane, which will secure the vessel's with efficient handling operations for a sustainable future. The innovative crane ensures fast and safe cargo transfer, and the system allows the load to keep close to the crane tip from the deck level to the TP platform.

Additionally, a stepless access walk-to-work-system is able to work from 15 to 30 metres above sea level, and is suitable for both personnel and cargo transfer.

Purus Energy, a UK based offshore wind services provider, describes itself as committed to contributing to the next generation battery hybrid service, operation and transfer vessels to the sector. The two CSOVs represent part of Purus Wind's contribution to a clean energy industry as its members set out to decarbonize.

The project has been awarded funding under the Norwegian government's Green Platform Initiative. The goal of the vessels is to secure environmental benefits through power operations that have minimum additional energy sources.

Business Head of Purus Wind, Tom Nevin, stated: "These vessels will support a pathway for our clients to decarbonize their operations and to maintain our position as a leader with the lowest carbon offshore wind support fleet. We are also very excited about the potential of what will be the next generation of a very successful design with the ability convert to methanol with the flexibility of hybrid and zero emission mode."

CEO of VARD, Alberto Maestrini, commented: "VARD has a high focus on utilizing our innovation power to meet the world’s changing needs. This innovation and development are only possible in close collaboration with our customers and partners seeking sustainable solutions. We highly appreciate the reception our priority on the offshore wind segment has had in the market and will continue to develop our designs and tailor-made specialized vessels in accordance with our goal to enable sustainable business at sea."

The hull of the first vessel will be built in VARD in Romania for outfitting and commissioning, with delivery from one of VARD's yards in Norway in Q2 of 2025. The second vessel will be built in Vietnam at VARD Vung Tau, with delivery in Q2 2026.
