NOV, the parent company of GustoMSC, will deliver the equipment and design of Cadeler’s first F-class jack-up vessel. The new F-class is a bespoke version of the GustoMSC NG-20000X model specially designed as a hybrid wind turbine and foundation installation jack-up vessel.
In addition to the first two X-class units, this will be Cadeler’s third GustoMSC-designed jack-up vessel under construction at COSCO Heavy Industries.

Largest in the industry
The Cadeler F-class is designed on similar specifications as the X-class. These self-propelled jack-up vessels are the largest in the industry, with 5600 m2 of deck space and a carrying capacity of more than 17,600 tonnes.
Featuring a larger main crane capacity than the X-class, the F-class vessel’s design allows it to quickly convert from a foundation to a wind turbine installation unit. This new hybrid jack-up vessel is designed to transport and install up to six XL monopiles per round-trip, substantially improving operational efficiency and reducing the installation’s total carbon footprint.

Rack and pinion jacking system
The F-class vessel will have an NOV variable speed drive rack and pinion jacking system. The integrated system offers high performance, reliability, and safety for thousands of jacking moves throughout the vessel’s lifespan. The jacking system will include a regenerative power solution where the generated power is fed back into the vessel system, providing fuel savings and emission reductions.
The new F-class vessel is expected to be delivered in Q4 2025. Cadeler is currently in discussion for an XL monopile foundation installation contract in the North Sea. Installation is expected to commence in Q2 2026.
