Order Placed for World’s Largest Cutter Suction Dredger

Jan De Nul Group has placed an order for a large self-propelled cutter suction dredger JDN8069 with the Croatian shipyard Uljanik Brodogradiliste.

The vessel was designed by Jan De Nul’s in-house design department. With seven large self-propelled cutter suction dredgers, Jan De Nul Group can boast much experience in rock dredging and dredging at high sea. This experience provided the basis for new cutter suction dredger concept.

The total installed diesel power will be over 40.000 kW, which is approximately 50% more powerful than the J.F.J. De Nul, currently the largest cutter suction dredger in the world.

The cutter power amounts to 8,500 kW and the cutter ladder weighs around 2,000 tonnes. These figures are unrivalled and make the vessel the ultimate tool for dredging hard rock.
