Cadeler has ordered its second F-class vessel. The  hybrid design allows the vessel to convert from being a foundation installation unit to a wind turbine generator installation vessel within a short period of time.


Cadeler is currently building two X-class as well as an F-class vessel, which are set to be delivered from H2/2024 onwards. The new F-class vessel is expected to be delivered in the second half of 2026. All vessels will be built by COSCO Heavy Industries in Qidong, China, and will sail under Danish flag.

It has been agreed between the parties not to disclose the final price of the contract.

“Due to our solid partnership with Cadeler and our strong order book of Cadeler jack-up vessels, we have been able to offer Cadeler a unique deal in the industry. We are honoured that Cadeler continues to see us as a strategic business partner that can deliver the state-of-the-art vessels that the market requires”,
said YuJian, Commercial Director from COSCO Shipping (Qidong) Offshore.

The second F-class vessel will be built on similar specifications to the first F-class vessel, with a deck space of 5,600m2, a payload of more than 17,600 tons and a main crane capacity to be disclosed at a later date. The vessels are designed  to transport and install seven complete 15 MW turbine sets per load or six sets of 2XL monopile foundations. In line with the X-class vessels, the F-class aim to cater for some of the largest dimensions in the offshore wind industry.

The X- and F-class vessels are built in close cooperation with Cadeler’s strategic partners, which include GustoMSC NOV, Kongsberg, Huisman and MAN Energy.

Cadeler’s CEO, Mikkel Gleerup said: “The decision to build another F-class vessel is based on the strong market demand for assets specialising in installing foundations. Our yet-to-be-build F-class vessels have already been sought after by our customers. As announced in August, we have signed a firm contract with Ørsted and have also entered a long-term agreement with an undisclosed customer booking the F-class from 2027 to 2030. These commitments are only possible because our clients believe in our abilities to meet their demands with increased flexibility and to offer state-of-the-art vessels that are fit to meet requirements from a fast-growing market.”
