Cadeler signs two significant contracts for full-scope foundation and turbine transportation and installation

Copenhagen, 10 November 2025 – Cadeler today announces the signing of two firm contracts covering the full-scope transportation and installation of offshore wind turbines and their foundations for an upcoming offshore wind farm development with a combined value projected to be approximately EUR 500 million.

The foundations transportation and installation (T&I) campaign is set to commence in early 2029 and to be executed using one of Cadeler’s newbuild A-class vessels. This contract, the third full-scope foundation T&I campaign for Cadeler, once again reaffirms the company’s position as a full-service provider in the foundation T&I space. The turbine installation scope is scheduled to begin in early 2030 and will be carried out by one of Cadeler’s O-class jack-up vessels, with completion expected by late 2030.

The contracts are subject to the client’s investment decision in the project. Should the client be unsuccessful the agreements may be terminated subject to a termination fee.

Mikkel Gleerup, CEO of Cadeler, comments: “This project reinforces Cadeler’s position as a full-service T&I partner in the foundations space and demonstrates that our strategic direction is aligned with current market demands. With our fleet of nine wind installation vessels – and three additional under construction – Cadeler continues to deliver the flexibility, efficiency, and innovative solutions required to execute increasingly complex projects and to support the necessary build-out of offshore wind globally.”
