Jan De Nul Group, the leading dredging specialist has ordered a cutter-suction dredger from 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. JDN8069 is due for delivery at the beginning of 2017 and will operate globally. Upon completion, the vessel will be the largest of its type in the world.
The new vessel will be able to boast of 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.
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 cutter- and hopper-dredger new buildings 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-developed technologies to optimise their economic and ecological performance, including:
- high-efficiency, TCA-type, exhaust-gas turbochargers
- advanced, electronic fuel-injection systems
- electronic hardware and software for engine control, monitoring and diagnosis in the form of MAN Diesel & Turbo’s proprietary SaCoSone system.
