Vard has delivered the commissioning service operation vessel (CSOV) Purus Chinook to Purus, a vessel that is the owner’s first newbuild for the offshore wind market
Delivery of the company’s first newbuild CSOV took place on 29 April 2025, ahead of schedule. The vessel is due to head straight to a contract with Vestas to support the company’s offshore wind operations.
The vessel is noteworthy for a number of reasons, not least the adoption of the strictest comfort class notations, C2 (climate) and V1 (noise and vibration). The notation ensures optimal onboard temperature regulation, reduced noise and vibration throughout the vessel.
The CSOV is 87.7 m in length and of Vard 4 19 design, a design developed by Vard Design in Ålesund and customised for Purus.
The newbuidling is designed for excellent sea-keeping and fuel efficiency with a modern hull and optimized propulsion system and has a battery hybrid propulsion system allowing for zero-emission operation for periods. It is also methanol-ready.
The hull was constructed at Vard Shipyards Romania in Tulcea with final outfitting and commissioning completed at Vard Søviknes.
The CSOV has an electric controlled motion compensated crane from Seaonics which is designed for efficient and safe cargo handling. The stepless walk-to-work system on the vessel is capable of seamless operation between 15 m and 30 m above sea level.
Purus Chinook has accommodation for 120 people, an 18-m helideck and a new 12-passenger daughter craft designed by Chartwell.
The newbuild is the first of a quartet of CSOVs ordered by the company, with the second, Purus Coriolis, to be delivered in 2026.
