New MAN 49/60DF engine confidently powers ships into the long run

MAN Power Options sees twin gas engines as the important thing to the maritime power transition and the 49/60DF is a superb new alternative for vessel house owners with formidable emission-reduction targets on their agendas. The engine gives operators full fuel-flexibility: they’ll select from the varied decarbonisation paths that open up as new fuels make their method into the marine trade.

The brand new engine can run on LNG, diesel, or heavy gas oil (HFO), so its gas flexibility ensures the bottom gas prices. Right this moment, biofuels or artificial fuels can already be blended in. Trying to the long run, the engine’s effectivity and low methane slip guarantee compliance with, for instance, FuelEU Maritime till 2040 operating on typical LNG and assisted by exhaust gasoline aftertreatment options. Past that, prospects can decide to mix in biofuels, e-fuels, or different options MAN ES can have developed by then.

The MAN 49/60DF was designed with future retrofits in thoughts, and the methanol-ready notation was obtained in early 2023. So, when laws change into extra stringent or circumstances change into beneficial, retrofit options are simple to implement. The retrofit equipment for methanol operation is in improvement.

Future adaptation to as but unexpected circumstances might be made supported by MAN’s newest technology engine automation system, the MAN SaCoS 5000. Geared up with this method, the MAN 49/60DF can adjust to the best cyber safety necessities.

The engine’s new Adaptive Combustion Management ACC 2.0 is without doubt one of the key enablers for improved effectivity and efficiency. ACC 2.0 adapts robotically to altering ambient circumstances, various gas qualities, and engine put on. With ACC 2.0, the MAN 49/60DF achieves benchmark ranges of dynamic engine operation, enabling vessels to function in gasoline mode even in difficult conditions like maneuvering.

The MAN 49/60DF already units new benchmarks in effectivity, with 171 g/kWh liquid gas consumption at 85% MCR and 6990 kJ/kWh gasoline consumption at 85% MCR. Whereas saving gas price is a elementary goal for any operator, environment friendly vessel propulsion will change into much more necessary beginning in 2024: the European Union has determined to incorporate maritime transport in its EU Emissions Buying and selling System (ETS), requiring operators to buy carbon dioxide (CO2) emissions certificates. Vessels powered by MAN 49/60DF will due to this fact profit twice: from low gas price and decrease prices for CO2 emissions certificates.

Prospects can order the MAN 49/60DF as an inline engine with 6, 7, 8, 9, or 10 cylinders, or as V-type engine with 12 or 14 cylinders. The output ranges from 7800 – 18 200 kW. It may be used as the primary engine for mechanical or electrical propulsion. It satisfies IMO Tier III necessities in gasoline operation. With the addition of MAN SCR, it could additionally fulfil IMO Tier III in liquid gas mode.

The engine’s future path is highlighted by a latest improvement: the twin gas electrical+ (DFE+) propulsion idea for LNG carriers. Primarily based on the MAN 49/60DF engine and ABB’s Dynamic AC energy distribution and management system, it helps lower carbon footprints and gas payments for LNG carriers by enabling extra operational flexibility and opening one other path for compliance with future emission laws.
