Jan De Nul has selected a customised vessel design from Ulstein Design & Solutions AS 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. The vessel is scheduled for delivery in 2028. The basic design is based on a robust and globally proven subsea vessel design.

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.

 Muysewinkel Thomas, Project Manager Vessel Construction at Jan De Nul says:

   – We chose Ulstein because of their proven vessel design, which provides a strong foundation to integrate all of our operational requirements. This collaboration allows us to combine reliability with tailored solutions for our operations. We look forward to a close and productive cooperation throughout the process. Together, we will deliver a state-of-the-art vessel fully adapted to the needs of our clients and crew.

 Rolf Petter Almli, sales manager at Ulstein Design & Solutions AS states:

 A NEW CUSTOMER
 – We greatly appreciate the confidence Jan De Nul has shown by selecting Ulstein Design & Solutions. Jan De Nul is a new customer to us, and we look forward to contributing with a modern and operationally flexible vessel design,

 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.

ULTRA-LOW EMISSION VESSELS
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. Thanks to the ULEv system, the vessel complies with the strict European Stage V emission standards for inland waterway vessels. Moreover, the NOx emissions are reduced to such an extent that this vessel meets the even stricter EURO VI emission limits.
