Cadeler has signed a contract with Vestas for the transportation and installation of 64 wind turbines, each with a 15 MW capacity, that will be installed at the
He Dreiht wind farm in the German part of the North Sea. The preferred supplier agreement was signed in November of last year and has now been turned into a conditional order agreement, signed by all involved parties.

The turbine installation is scheduled to commence in the second quarter of 2025 and will be finished by the end of the year. It will be executed by one of Cadeler’s two O-class vessels, which will feature a new crane with a lifting capacity of 1,600 metric tons at a radius of 40 metres.

“This project builds on the positive collaboration we have had with Vestas for years. We are excited to see how our newbuild cranes will come in use when we install turbines of these record sizes and demonstrate the extensive know-how and experience of our on and offshore team as well as superior capabilities of our upgraded O-class vessels. We look forward to joining forces with Vestas once again on this ground-breaking project.”
said Mikkel Gleerup, CEO of Cadeler.

Flemming Ougaard, Senior Vice President of Construction in Vestas Northern & Central Europe, stated: “We are pleased to partner up with Cadeler once again and further develop the relationship between our companies. Choosing Cadeler as the supplier of transportation and installation of V236-15.0 MW turbines for the He Dreiht project is based on the strong partnership we have developed on previous projects, and we are confident that Cadeler is the right partner to install our new turbine on its first large-scale project. Our companies are currently successfully collaborating on the Seagreen project, Scotland’s largest windfarm.”  


He Dreiht is being developed as a subsidy-free wind farm, and was awarded grid connection agreement in the German capacity auction held in April 2017. The 900 MW project is located approximately 85 km north of the Borkum Island and 95 km to the west of the Helgoland Island. Its operation and maintenance will be conducted from EnBW's base in Emden.

Last month, Heerema Marine Contractors revealed that it had secure an offshore wind foundation installation contract for the offshore wind farm. It followed an announcement in March from Seaway 7 ASA that it has been awarded a contract by EnBW for the project's Engineering, Procurement, Installation and Commissioning  works of inter-array grid cables.
