NOV confirmed on Tuesday that it has won contracts to equip and design the first F-class jack-up vessel from offshore wind installation company Cadeler.
The recently ordered F-class lift is a customized version of the GustoMSC NG-20000X designed as a hybrid wind turbine and foundation installation jack-up vessel.
Along with the first two X-class units, which will be able to install next-generation offshore wind turbines, this will be Cadeler’s third GustoMSC-designed jack-up vessel under construction at COSCO Heavy Industries.
The F-Class Cadeler is designed to similar specifications as the X-Class. These self-propelled jack-up vessels are the largest in the industry, with 5,600 m2 of deck space and a load capacity of over 17 600 tons.
Featuring a larger main crane capacity than the X-class, the F-class vessel’s design allows it to convert from a foundation to a wind turbine installation unit.
The new hybrid jack-up vessel is designed to transport and install up to six XL monopiles per round trip, improving operational efficiency and reducing the installation’s total carbon footprint.
The F-class vessel will be equipped with a NOV variable speed drive rack and pinion lifting system.
“The unique integrated system provides high performance, reliability and safety for thousands of lifting movements throughout the lifetime of the vessel. The lifting system will include a regenerative power solution where the energy generated is fed back into the vessel’s system, resulting in fuel savings and emission reductions,” NOV said.
The new F-class vessel is expected to be delivered in the fourth quarter of 2025. Cadeler is currently in discussions for an XL monopile foundation installation contract in the North Sea. Installation is expected to begin in the second quarter of 2026.
