Technology and Equipment

To be able to offer innovative solutions the material must have the newest and most advanced technologies on board. For that reason, Jan De Nul Group invests continuously in research and development to build and operate state-of-the-art vessels and equipment using best practice and techniques.

The in-house engineering department designs new equipment or works out modifications to existing material. The equipment is built or rebuilt in order to meet the market demands. That is why Jan De Nul Group can promptly respond to specific needs, wherever in the world these may arise. Thanks to its continuous investments in technology, Jan De Nul Group is always one step ahead.

Investing in the fleet

The dredging fleet of Jan De Nul Group is the world’s most modern and most diverse fleet, this being the result of a resolute investment policy in its own equipment. The new vessels with their advanced technology on board are designed by the Group’s ’in-house’ engineering departments. Furthermore, Jan De Nul Group directly manufactures and supplies the dredging equipment to the shipyard, which is unequalled in the dredging sector.

The fleet includes a number of the most powerful self-propelled cutter suction dredgers and largest trailing suction hopper dredgers in the world.  Jan De Nul Group is the proud owner of several record breaking vessels including: the J.F.J. De Nul, the world’s most powerful cutter suction dredger, the identical Cristóbal Colón and Leiv Eiriksson, the world’s largest trailing suction hopper dredgers with a hopper capacity of 46,000 m³ and capable of dredging to a depth of 155 m and the identical Simon Stevin and Joseph Plateau, the world’s largest rock installation vessels.

Investing in dry equipment

For its dry excavation activities, Jan De Nul Group owns more than 500 heavy machines. Jan De Nul Group also invests in specific equipment needed for executing one particular contract: either new machines are purchased, or existing machines are rebuilt in-house. If for a certain project a new machine is required, the in-house Design and Engineering Department will work out the ideal solution.

Finally, Jan De Nul Group has its own maintenance and repair workshop as well as a state-of-the-art metal processing division that can execute the most complicated turning, milling and welding works. Examples are a bucket-wheel excavator for earthmoving works or the Starfish, an amphibious excavator that, thanks to the raised location of engine and cabin, can work in depths up to 6 to 10 metres.

For its environmental activities Jan De Nul Group has a comprehensive range of specialised equipment at its disposal covering more than 50 mobile water treatment plants, as well as several permanent and mobile sediment and soil treatment plants.
