HOUSTON — NOV has been awarded contracts for the equipment and design of Cadeler's second F-class jackup vessel.
The F-class is a bespoke version of the GustoMSC NG-20000X model specially designed as a hybrid wind turbine and foundation installation jackup vessel.
In addition to the two X-class vessels, which are set to be delivered from second-half 2024 onward, this will be Cadeler's fourth GustoMSC-designed jackup vessel under construction at COSCO Heavy Industries.
The Cadeler F-class vessels are designed with similar specifications to the X-class vessels, which were awarded in 2021. These self-propelled jackup vessels are the largest in the industry, with 5,600 sq m of deck space and a carrying capacity of more than 17,600 tons.
The unique F-class features a larger main crane capacity when compared to the X-class, which allows it to quickly transition from foundation installation to wind turbine installation operations. The dual-scope jackup vessel is designed to transport and install up to six 2XL monopile foundations per round-trip, reducing the number of transits needed for each project.
The second F-class vessel also will be outfitted with the NOV variable speed drive rack and pinion jacking system, including a regenerative power solution where the generated power is fed back into the vessel system. These features substantially improve operational efficiency and reduce the installation's total carbon footprint.
The second F-class vessel is expected to be delivered in second-half 2026.
