Jan De Nul has contracted Ulstein Design & Solutions AS to provide a customized vessel design for the latest addition to its offshore fleet. The subsea cable trenching vessel, scheduled for delivery in 2028, will be built at the CMHI shipyard in China. This collaboration marks a significant milestone between the two maritime innovators, utilizing a proven subsea vessel platform to support extensive trenching operations worldwide.
The custom-designed vessel features a modular configuration and the signature Ulstein X-BOW® hull, which improves crew comfort and reduces fuel consumption. Engineered for precision performance, the ship will be purpose-built for subsea trenching—the process of creating protective channels on the seabed to bury pipelines, power cables, and telecommunication lines. Its design supports a broad range of offshore sectors, including energy, construction, and deepwater operations.
In line with Jan De Nul’s environmental standards, the vessel will be equipped with Ultra-Low Emission vessel (ULEv) technology. This advanced dual exhaust filter system removes up to 99% of nanoparticles and significantly reduces nitrogen oxides (NOx) and other pollutants. The vessel’s engines are designed to run on biofuel and green methanol, further contributing to a substantial reduction in CO2 emissions during offshore projects.
