Cadeler Acquires Wind Keeper Vessel to Expand Offshore Wind O&M Capabilities
Cadeler is powering up for the next phase of offshore wind expansion. The Danish installation specialist has announced its acquisition of the Boqiang 3060 jack-up vessel—soon to be christened the Wind Keeper—marking a strategic push into operations & maintenance (O&M) support for large-scale offshore wind farms.
New Flagship for Cadeler: Wind Keeper Joins the Fleet
Built in 2025 by Shanghai Boqiang Heavy Industry Group, the Wind Keeper is fitted with top-tier European systems designed for O&M operations in some of the world’s most demanding maritime environments. Cadeler expects to take delivery in the third quarter of 2025.
Vessel Specifications and Key Technology Highlights
Crane, Propulsion, and Positioning Systems
- Crane: Huisman 2,200-tonne lifting capacity
- Dynamic Positioning: Kongsberg DP2 system
- Engines: MAN
- Propulsion: Siemens
Jack-Up Capability for Harsh Offshore Environments
Wind Keeper features 120-meter jack-up legs, enabling stable positioning even in challenging offshore wind farm sites. This makes it ideally suited for O&M support and future-proofed installations in the 15 MW segment.
Strategic Role in Offshore O&M Market Expansion
With global offshore wind capacity surging, particularly in Europe and Asia-Pacific, the need for robust O&M infrastructure has never been greater. Wind Keeper addresses this demand head-on with high load, lift, and station-keeping performance, alongside modular upgrade potential.
Delivery Timeline, Upgrade Plans, and Fleet Synergies
Although the purchase price was not disclosed, Cadeler confirmed it was “significantly below replacement cost.” The vessel will undergo upgrades post-delivery to align with Cadeler’s fleet standards and integrate seamlessly into existing O&M and installation contracts.
CEO Insight: Supporting the 15 MW Era of Wind Installations
“As an installation-capable, service-oriented asset, the Wind Keeper will be a valuable addition to our fleet,” said Mikkel Gleerup, CEO of Cadeler. “She complements our existing vessel portfolio and allows us to provide much-needed service support to our clients’ offshore assets.”
Conclusion: Wind Keeper Positions Cadeler for O&M Leadership
The acquisition of Wind Keeper is more than fleet expansion—it’s a forward-looking investment in offshore wind’s maintenance backbone. As turbine sizes grow and global demand for uptime soars, Cadeler’s move cements its role as a reliable partner in the wind energy lifecycle.
