MAN Diesel & Turbo (MDT) has unveiled the successor to its 48/60CR marine diesel engine in the company’s 4x line of high-performance engines.
The MAN 45/60CR engine will initially be available as 12V and 14V versions that will produce power outputs, of 15,600 and 18,200 kW, respectively, with 6L to 10L inline versions following at a later stage.
Wayne Jones, MDT’s Chief Sales Officer, said: “The new engine combines the best features of the current 48/60CR, such as MAN’s common-rail system with ECOMAP capability and adds new technologies such as two-stage turbocharging for an unrivalled specific fuel oil consumption. The resultant reduction in operating expenses and positive environmental impact are sure to attract strong market interest.”
MDT said that the 45/60CR’s power increase and low consumption are particularly aimed at key, lifecycle-cost-oriented applications, such as cruise liners, ropaxes, among others. The engine was designed from the beginning as a family concept that will accommodate future derivatives, for example, such as dual-fuel operations.
The first set of V-type engines will be available from the end-2020 with delivery of the first L-type engines due from 2022.
Calculations, based on a representative load-profile of a cruise vessel, show that a ship operating with an MAN 45/60CR engine can enjoy a fuel-oil cost benefit of 5 to 12% in comparison with a vessel powered by an equivalent engine from other manufacturers.
For a cruise vessel of around 120,000 – 150,000 gt with 60 – 65 MW of installed power and an assumed fuel price of €500 per tonne, this translates into annual savings of €0.9 to 2.4 mill when fitted with 45/60CR type engines.
