General – Newbuilding
Jan De Nul has selected a customised vessel design from Ulstein Design & Solutions for its latest addition to its offshore fleet.

The realisation of the trenching vessel marks a milestone in the collaboration between two leading maritime innovators. Built at the CMHI shipyard in China, the vessel is scheduled for delivery in 2028.
This custom-designed vessel, with its deck space and deadweight, will support extensive trenching operations.
Subsea trenching is the process of creating a protective channel on the seabed to bury pipelines, power cables, and telecommunication lines.
Ulstein’s vessel design is engineered for modularity, supporting a broad range of offshore sectors, including energy, construction, and deepwater operations.
This version will be purpose-built for subsea trenching, ensuring precision performance.
The ULSTEIN X-BOW hull design improves comfort, reduces wave resistance, and fuel consumption.
The vessel is an Ultra-Low Emission vessel (ULEv). ULEv is a highly advanced dual exhaust filter system which removes up to 99% of nanoparticles from emissions using a diesel particulate filter and a reduction system for nitrogen oxides (NOx).
The system also significantly reduces exhaust gas pollutants. The engines of the vessel can run on biofuel and green methanol, reducing CO₂ emissions.
Jan De Nul will also convert its vessel Henry Darcy into a trenching support vessel equipped with a subsea robot specialised in burying cables in shallow waters.
