Purpose-built CSOV delivered as planned

Windward Athens, the first Commissioning Service Operation Vessel (CSOV) for Windward Offshore, has been delivered on time from Vard Brattvaag. The vessel marks an important milestone in our collaboration with the newly established ship owner and supports the rapid expansion of the offshore wind industry.

The challenge

Windward Offshore set out to enter the offshore wind service market with a modern fleet of advanced CSOVs. The challenge was to deliver a highly complex, next-generation CSOV, built for demanding offshore wind operations, while maintaining schedule and quality.

Value for client

Delivered on time

VARD’s integrated value chain, spanning design, hull construction, outfitting, and commissioning, ensured the vessel was delivered according to schedule.

Future-ready

A purpose-built CSOV with hybrid propulsion prepared for future conversion to methanol, motion-compensated offshore systems, and advanced digital systems, enabling safe, efficient, and sustainable operations from day one.

Operational efficiency and comfort

High-comfort accommodation for up to 120 people and smart integrated systems support crew welfare, operational reliability, and seamless offshore wind service activities.

What we did

In close collaboration with Windward Offshore, we designed, equipped, and built a CSOV tailored to their operational needs. Delivered from Vard Brattvaag and based on the energy-efficient VARD 4 19 design, the vessel features motion-compensated gangway and crane systems, SeaQ integrated automation and energy management, high-comfort accommodation for 120 people, hybrid propulsion prepared for future conversion to methanol, and advanced digital systems, ready for safe, efficient, and sustainable offshore operations.

The delivery of Windward Athens is a defining moment for Windward Offshore. The on-time delivery of Windward Athens is not only a testament to the strong commitment and excellent work of the Windward team but also the professionalism of VARD and the equipment makers selected for our four vessels.
