Jan De Nul Group is expanding its fleet with new Jan De Nul subsea cable vessels to support offshore energy projects. This investment reflects rising demand for subsea cable infrastructure driven by offshore wind, interconnections, and global energy transition initiatives.
New Vessels Enhance Trenching and Installation Capabilities
Jan De Nul is adding two advanced vessels to strengthen its trenching operations. The first, Fleeming Jenkin, is a purpose-built vessel equipped with an underwater trenching robot capable of burying cables up to five meters below the seabed.
Ulstein Design & Solutions designed the vessel, and China Merchants Heavy Industry will construct it. In addition, the ship will feature ultra-low emission (ULEv) technology. Its engines can run on biofuel and are prepared for future methanol use, supporting sustainability goals.
At the same time, Jan De Nul will convert a second vessel, Henry Darcy, to focus on shallow-water trenching projects. This vessel will carry a trenching robot supplied by Osbit, designed for nearshore cable burial.
Supporting Growing Offshore Energy Demand
These new Jan De Nul subsea cable vessels improve the company’s ability to deliver flexible installation and protection solutions across a wide range of offshore projects. The company operates globally and supports both cable installation and long-term protection.
Jan De Nul recently introduced the rock installation vessel George W. Goethals, which stabilizes subsea cables by applying protective rock layers. Therefore, the company continues to expand its capabilities across the full cable lifecycle.
With these additions, Jan De Nul now has four vessels under construction dedicated to subsea cable work, along with one vessel undergoing conversion. This expansion highlights ongoing investment in offshore renewable energy infrastructure and subsea transmission systems.
