Jan De Nul Group is ordering another XL cable-laying vessel, identical to the Fleeming Jenkin, which will be delivered in 2026 and has already been booked for its first projects.
The new XL ship will be the fifth vessel in Jan De Nul Group’s cable-laying fleet.
Jan Van de Velde, director of new building at the Jan De Nul Group, said: “We are and remain a big believer in the transition to renewable energy.
“With this second XL cable-laying vessel, we continue to reinforce our pioneering role.
“Both vessels combine all the cable installation expertise we have built up over the past decade.
“The result are vessels that operate very efficiently and have a much smaller carbon footprint.”
Like the Fleeming Jenkin, the vessel will be 215 metres long and can transport 28,000 tonnes of cables.
This will make them the largest capacity cable-laying vessels in the world, Jan de Nul said.
Thanks to technology on both vessels, designed by Jan De Nul Group’s own specialists, they can lay cables in both shallow and ultra-deep waters up to 3,000 metres.
The vessels can handle cable tensions of up to 150 tonnes.
Both vessels are equipped with Ultra-Low Emission vessel (ULEv) technology, an advanced dual exhaust filter system.
This system removes up to 99% of nanoparticles from emissions using a diesel particulate filter (DPF) and a selective catalytic reduction system (SCR) for NOx removal, Jan De Nul said.
Thanks to the ULEv system, the vessels comply with the strict European Stage V emission standards for inland waterway vessels, it added.
Moreover, the NOx emissions are reduced to such an extent that these vessels meet the even stricter EURO VI emission limits, according to the company.
The hybrid power plant combines the generators with a 2.5MWh battery and drive technology, designed for peak load shaving, load smoothening, spinning reserve and optimized engine loading, Jan De Nul said.
The vessels can be powered by biofuel and green methanol which significantly reduce CO2 emissions, it added.
