Cutter-Suction

MAN Diesel & Turbo has secured an order to power Jan De Nul’s new self-propelled, cutter-suction dredger to be built at Croatian shipyard, Uljanik Brodogradiliste in Pula.

Under this contract, MAN will deliver one MAN 14V48/60CR and two MAN 9L48/60CR engines.

After the delivery, the vessel would be the largest of its type in the world, the company stated.

MAN Diesel & Turbo Four-Stroke Marine vice-president and head Lex Nijsen said: "This new vessel represents a significant development within the dredger segment in that, up to now, the largest installed power on similar vessels was approximately 27-28MW, a figure the new vessel easily surpasses.

"I’m confident this order will help Jan De Nul Group maintain its strong presence in the dredger market."

The new vessel, designated as JDN8069, is expected to be delivered at the beginning of 2017.

"I’m confident this order will help Jan De Nul Group maintain its strong presence in the dredger market."

The MAN L/V 48/60CR engine is claimed to be one of the most successful engine types used in dredging applications, while the 48/60CR engines are equipped with key, in-house-developed technologies to optimise their economic and ecological performance.

The vessel will also feature three step-up Renk Rheine gearboxes for its diesel-electric plant.

In addition, Renk will provide the vessel with gearboxes for the cutterhead drive as well as for the dredge and booster pumps.

The total installed diesel power of the vessel will be over 40.000kW, which is around 50% more powerful than the present largest cutter suction dredger, J.F.J. De Nul.
