Vard has handed over NB 973, a newbuild Commissioning Service Operation Vessel (CSOV), to Purus, ahead of contractual schedule
This is said to be the first CSOV to receive DNV’s COMF C2 V1 class notation for climate, noise and vibration, which Vard describes as a major industry breakthrough, setting a new global benchmark for offshore working conditions. The strictest comfort class notations – C2 (climate) and V1 (noise and vibration) – reflect Vard’s and Purus’ dedication to health, safety, and well-being at sea. It ensures optimal onboard temperature regulation, reduced noise and vibration throughout the vessel, directly supporting crew welfare and long-term performance.
Cathrine Marti, CEO Vard, said: “With NB 973, we’re not only delivering a highly advanced and sustainable vessel – we are redefining the standards for life at sea. This delivery reflects the power of collaboration, innovation, and commitment across our entire value chain. Congratulations to Purus on this milestone, and a heartfelt thank you to the dedicated Vard teams who made it possible.”
NB 973 is an 87.7m CSOV of the Vard 4 19 design, developed by Vard Design in Ålesund and customised for Purus to meet the challenges of the offshore wind industry. The vessel is designed for:
- Excellent sea-keeping and fuel efficiency with a modern hull and optimized propulsion system
- Battery hybrid propulsion allowing zero-emission operation for periods
- Methanol-ready configuration for future green fuel options
- Focus on operability, logistics flow, and crew comfort at sea
The vessel represents Purus’ continued commitment to operational excellence and sustainable offshore solutions. It is claimed to highlight the strength of Vard’s integrated value chain. The hull was constructed at Vard Shipyards Romania – Tulcea, and the final outfitting and commissioning were completed at Vard Søviknes, demonstrating smooth cooperation across locations and disciplines.
The CSOV features equipment from Vard subsidiary Seaonics, including the electric controlled motion compensated (ECMC) crane. This innovative system keeps loads stable and close to the crane tip from deck to TP platform, ensuring efficient and safe cargo handling. The stepless walk-to-work system, capable of seamless operation between 15m and 30m above sea level, further enhances the vessel’s operational capabilities for personnel and cargo transfer.
NB 973 also showcases the expertise of Vard Interiors, delivering key systems that support crew comfort and high-quality operations onboard. This includes the complete HVAC system, provision and refrigeration systems, piping, and interior outfitting. These deliveries are crucial to ensuring optimal indoor climate, and functional living and working spaces – all tailored for life at sea.
NB 973 is equipped with a complete SeaQ package from Vard Electro, covering all core systems for smart, safe, and efficient operations. This includes the SeaQ Bridge (Integrated Bridge System), SeaQ Power (drives, switchboards, ESS), SeaQ Control (IAS, PMS, EMS, Green Pilot), and SeaQ Communication (CCTV, LAN/WLAN, telephony, entertainment) – enabling optimised vessel performance and comfort.
