MAN Engines Ordered for World’s Largest Cutter-Suction Dredger

Jan De Nul Group, the leading dredging specialist, is set to further expand its modern fleet with a selfpropelled, cutter-suction dredger to be built at Croatian shipyard, Uljanik Brodogradiliste in Pula.
The vessel, currently designated ‘JDN8069’, will feature 1 × MAN 14V48/60CR + 2 × MAN 9L48/60CR engines as well as 3 × 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. Upon completion, the vessel will be the largest of its type in the world.
Lex Nijsen – Vice President and Head of Four-Stroke Marine – MAN Diesel & Turbo, said: “Jan De Nul
Group knows MAN very well and much of its fleet features our engines. 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.”
Popular dredging choice
The MAN L/V 48/60CR engine type is one of the most successful engine types used in dredging applications. Among the 56 such engines MAN Diesel & Turbo currently has on order for various marine applications, 14 alone are bound for installation aboard cutterand
hopper-dredger newbuildings for customers in Benelux and China. All engines will be built at MAN’s main facility in Augsburg, Germany.
The 48/60CR engines are equipped with key, in-house-de- veloped technologies to optimise their economic and ecological performance, including:
high-efficiency, TCA-type, ex- haust-gas turbochargers advanced, electronic fuel-in- jection systems
electronic hardware and software for engine control, monitoring and diagnosis in the form of MAN Diesel & Turbo’s proprietary SaCoSone system.
The new vessel will be able to boast of over 40,000 kW total diesel installed power, making it ap-

32/44CR characteristics
MAN common-rail engines are among the most technologically advanced in its portfolio with a segment-leading SFOC that significantly lowers emissions of soot and NOX over its complete oper - ating range. The company’s CR engines have already established a solid presence in several marine segments globally.
Specifically, the MAN 32/44CR is characterised by:
common-rail technology featuring optimised NOX vs. SFOC trade-off at every load point, independent of rpm
a high power output: 600 kW/ cyl for diesel-electric set-ups and CPPs; 510 kW/cyl for FPPs and dredgers
low fuel-consumption of 172.4 g/kW-hr for diesel-electric and CPP set-ups, and the use of high-efficiency turbochargers.
MAN 32/44CR engines are suitable for a variety of applications including fishing, ATBs (Articulated Tug Barges), anchor handlers, offshore construction vessels, dredgers and drill ships.
