Jan De Nul orders world’s most powerful cutter suction dredger

Luxembourg-based dredging and marine construction specialist Jan De Nul Group says it has placed an order for world’s largest and most powerful cutter suction dredger.

The order was placed at the Croatian shipyard Uljanik Brodogradiliste.

The large self-propelled cutter suction dredger, known as JDN8069, was designed in-house by Jan De Nul. The vessel’s total installed diesel power will be over 40,000 kW, which is approximately 50% more powerful than our J.F.J. De Nul, currently the largest cutter suction dredger in the world, according to the company. The cutter power amounts to 8,500 kW and the cutter ladder weighs around 2,000 tonnes.

The J.F.J. De Nul has been in operation since 2003 and has 27,240 kW of total installed diesel power. The vessel measures 141 meters long by 27.8 meters wide. Its cutter power is approximately 7,600 kW.

Cutter suction dredgers use a rotating cutter head to cut hard soil into fragments and then suck the waste into the dredger using pumps. The waste material can then be pumped ashore by way of a floating pipeline or loaded into a split hopper barge moored alongside.
