China-based Cosco Heavy Industries has received a contract from Danish company Cadeler for the construction of a new F-class vessel.

It is Cadeler’s second F-class vessel and the sixth vessel in its jack-up fleet for the offshore wind industry.

Featuring a hybrid design, the new vessel can be transformed from a foundation installation unit to a wind turbine generator installation vessel within a short period.

At present, Cosco is engaged in the construction of two X-class vessels as well as one F-class vessel, all of which are expected to be delivered in the second half of 2024.

The company plans to deliver the new F-class vessel in the second half of 2026. All the vessels will operate under the Danish flag.

The second F-class vessel will have features that are similar to the first F-class vessel. It will offer a deck space of 5,600m² and a payload of more than 17,600 tons.

Cadeler will use these vessels for the transportation and installation of seven complete 15MW turbine sets per load or six sets of 2XL monopile foundations.

Both the X- and F-class vessels are being constructed in coordination with Cadeler’s strategic partners, including GustoMSC NOV, Kongsberg, Huisman and MAN Energy.

Cadeler 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.”
