Cadeler Signs Significant Installation Vessel Reservation Agreement with an Undisclosed Client, Securing Capacity for Future Projects Worth Up to €700 Million

Copenhagen, 23 May 2024 — Today Cadeler announces the signing of a significant Installation Vessel Reservation Agreement with an Undisclosed Client for upcoming wind farm installation projects. If all options are exercised during the four-year agreement, the agreement would represent the largest deal in Cadeler's history, with the potential value of the projects to be executed under the agreement estimated to be in the range of EUR 400-700 million. The agreement secures the availability of one or more capable vessels from the full versatility of Cadeler’s fleet of wind farm installation vessels, including a newbuild A Class vessel currently under construction. Work is planned to commence in 2027.

Cadeler’s state-of-the-art fleet of vessels for offshore wind farm installation projects will be used for transport and installation of both foundations and wind turbine generators (WTGs), leveraging Cadeler’s fleet to deliver maximum efficiency, synergy, and flexibility. The signing of this reservation agreement emphasizes the growing importance of renewable energy initiatives and Cadeler's pivotal role in driving the transition to renewable offshore wind energy globally.

Our clients’ success is of the utmost importance – not only for commercial viability, but for our common efforts in pushing the envelope for what’s possible to achieve in offshore wind energy expansion."

The effectiveness of the agreement is contingent upon a successful outcome for the undisclosed client in an upcoming 2024 auction.
