X-class vessels: Building our green future

Designed to operate with the most advanced equipment in the industry

By the second half of 2024 and the first half of 2025, our two X-Class vessels will be ready. The two X-class vessels are designed to operate at some of the most difficult sites around the globe and with the most advanced equipment in the industry. The vessels will offer increased transit capacity, lowering the energy intensity of installation, reducing installation time and thereby lowering total cost of installing offshore wind farms.

With a deck space of 5,600m2, a payload of over 17,600 tons and main crane capacity of above 2,000 tons at 53 meters, the two new hybrid, cyber-secure vessels are very attractive to the industry. The vessels will be able to transport and install seven complete 15MW turbine sets per load or five sets of 20+ MW turbines, cutting down the number of trips needed for each project, thus accelerating installation speed and minimizing the carbon footprint. The vessels will have a 5,600 m2 deck space and can accommodate 130 people.

Our new vessels have been designed to reduce the impact on the environment. Not just in the final product, but also implemented in the process of building it. You can read more about our environmental responsibility here. 

The first X-class vessel will be ready in 2024 and has already been contracted for one of the largest offshore windfarms in the world: The 1.4 GW “Sofia” offshore wind power park in the North Sea, owned by RWE. For this project Cadeler will assist Siemens Gamesa with the transport and installation of 100 wind turbines of a size of 14 MW.
