Delivered April 2025

World`s first and delivered ahead of schedule

VARD proudly delivered Purus Chinook, a state-of-the-art Commissioning Service Operation Vessel (CSOV) to Purus, ahead of contractual schedule. This milestone delivery not only demonstrates VARD’s proven track record for on-time performance, but also introduces a major breakthrough in the offshore wind industry.

As the world’s first CSOV to receive DNV’s COMF C2 V1 class notation, Purus Chinook redefines standards for climate control, noise, and vibration at sea. This achievement reflects the shared vision of Purus and VARD to raise the bar on crew well-being, operational excellence, and sustainable innovation.

The challenge

In close collaboration with the customer, we set out to deliver a next-generation CSOV designed to meet the growing demands of the offshore wind industry — combining operational efficiency, low-emission propulsion, exceptional crew comfort, and readiness for future fuels — all while achieving early delivery in a highly competitive market.

Value for client

Delivered ahead of schedule

Our integrated value chain enables us to deliver ahead of the contractual delivery date, strengthens the customer`s competitive position in a dynamic market.

Crew well-being and performance

First CSOV to meet DNV COMF C2 V1 class notation – setting a new global standard for onboard climate, noise, and vibration comfort.

Cyber-secure operations

First vessel in the world to achieve DNV’s Cyber Resilience classification, setting a new benchmark for digital safety, operational integrity, and fleet-wide data security.

What we did

We worked closely with Purus to design a vessel tailored to their needs, using the VARD 4 19 design – optimized for operability, logistics flow, and crew comfort. Using our integrated value chain, the hull was built at Vard Shipyards Romania, Tulcea, and the final outfitting and commissioning were completed at Vard Søviknes in Norway. Purus Chinook was equipped with top-tier systems from our integrated value chain.

With Purus Chinook, we’re not only delivering a highly advanced and sustainable vessel – we are redefining the standards for life at sea.
