The MAN engines will power what is expected to be the largest cutter-suction dredger in the world

MAN Diesel and Turbo is to supply three of its MAN L/V 48/60CR engines for Jan De Nul Group’s new self-propelled, cutter-suction dredger – set to be the world’s largest.

The vessel, being built at Croatian shipyard Uljanik Brodogradiliste, will feature one MAN 14V48/60CR and two MAN 9L48/60CR engines as well as three step-up, RENK Rheine gearboxes for a diesel-electric plant. RENK will also deliver the gearboxes for the cutter-head drive as well as for the dredger and booster pumps.

“Jan De Nul Group knows MAN very well and much of its fleet features our engines,” said Lex Nijsen, vice president and head of four-stroke marine, MAN Diesel and Turbo. “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 27-28 MW, 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 48/60CR engines are equipped with key, in-house-developed technologies to optimise their economic and ecological performance, including high-efficiency, TCA-type, exhaust-gas turbochargers; advanced, electronic fuel-injection systems and electronic hardware and software for engine control, monitoring and diagnosis.

The new vessel will have over 40,000 kW total diesel installed power, making it approximately 50% more powerful than the Luxembourg outfit’s own J.F.J. De Nul, currently the largest cutter-suction dredger in the world. ‘JDN8069’ is due for delivery at the beginning of 2017 and will operate globally.
