Windward Offshore expands offshore wind activities with two additional state-of-the-art CSOV vessels.


Windward Offshore has exercised options, which were contained in the contract signed with Vard in October 2023, for the design and construction of two hybrid Commissioning Service Operation Vessels (CSOVs). As part of the order, the number of units ordered from VARD rises to four.

This order marks another significant milestone for Windward Offshore in advancing its commitment to deliver comprehensive offshore wind solutions. This strategic move not only underscores Windward’s dedication to meeting the substantial global demand for offshore wind energy and associated infrastructure but also serves as a testament to the demonstrated expertise and successful track record of VARD in the construction of offshore wind vessels.

The founding partners driving Windward Offshore’s innovative venture are SeaRenergy Offshore, Blue Star Group, Diana Shipping Inc. and SeraVerse. Together, they are united by a shared vision of pioneering excellence in the offshore wind sector.

“Windward Offshore is pleased to announce the execution of the Options for two further VARD 4 19 CSOVs, expanding our initial two vessel order to four vessels, and continuing our trusted relationship with VARD. All of our Vessels are designed to be equipped with the latest eco-friendly technologies with the goal of minimizing environmental impact and offering the highest safety standards to ensure safe and sustainable offshore operations.”,says Benjamin Vordemfelde – Managing Director Windward Offshore.

“We believe CSOV vessels will play a crucial role in the energy transition, and we are looking forward to offer our clients a comprehensive offshore wind service platform which combines a unique blend of the extensive maritime and offshore wind industry expertise by our partners”, says Christoph Geck-Schlich – Managing Director Windward Offshore.

With the four vessels on order, Windward Offshore is expanding its footprint in the industry. The first vessel is expected to be delivered in the second half of 2025, with the other three vessels joining the fleet in the course of 2026. With these modern vessels, Windward Offshore will support energy providers globally in constructing, commissioning, and maintaining offshore wind parks.

The initial announcement of the joint venture has already been well received by a variety of customers across different regions, demonstrating the strong market demand for Windward Offshore’s services. Additionally, also governments worldwide reaffirmed the need for offshore wind energy as an integral element of the energy transition at the world climate conference in 2023.
