New MAN Engines Marine Hybrid Systems

The following operating modes form the basis for the application-specific adaptation of the system designs: performance, efficiency and comfort.

Zero-emission mode

Energy for drive and power consumption provided by the battery

Emission-free and whisper-quiet – in zero-emission mode, the energy for the drive as well as the power consumption is provided exclusively by the battery. The battery can be charged in three ways: Shore connection in port, on-board gensets, main propulsion engines.

Benefits:

No noise and exhaust gas emissions
No vibration
Access to special protection zones

Diesel-electric mode

Reduce noise and exhaust gas emissions and save fuel

In diesel-electric mode, power supply and propulsion are provided by the existing on-board gensets and supported by the battery. This reduces main drive operating hours.

Benefits:

Low noise and exhaust gas emissions
Low vibration
Efficient operation (low fuel consumption)

Cross-over mode

Use different operating modes and maximise the economic benefit

In a two-engine system cross-over mode, both drivelines are operated in different modes. While one driveline is in diesel mode, the electric motor operates as an alternator and provides the electrical energy for the ship. In the second driveline, the main diesel engine is disengaged so that the e-engine receives its energy from the first diesel engine. It operates in motor mode and thus provides the drive energy.

Benefits:

Extremely economical operation
High range
Low vibration
Extended operating time until maintenance (TBO)

Hotel mode

Always ready for operation thanks to guaranteed power supply from the battery

In comfortable hotel mode, power is supplied by the battery alone while the diesel engines are switched off. The innovative technology ensures that power consumption is possible for an extended period without diesel engines. Independently of this, the batteries can be charged in parallel via a charging connection.

Benefits:

No noise & exhaust gas emissions
No vibrations
Full operational readiness without engines

Diesel mode

Full speed ahead plus charge power for the battery at the same time

In classic diesel mode, the energy for the drive is provided by the conventional diesel engine, or diesel engines in multi-engine systems. In this mode, the electric motor rotates along without function and without generating electricity. In addition, electricity can be generated in diesel mode to charge the batteries. In this case, the operating hours of the gensets are reduced.

Benefits:

Established drive
High range
Familiar flexible driving styles from economical to sporty

Boost mode

Maximum power thanks to the interaction of combustion engines and battery-powered electric motors

Here, different technologies complement each other and thus create the best result: when power is needed, the electric motor boosts energy from its power reserves. Boost mode therefore offers the highest power density and enables maximum performance. At the same time, it provides support in the lower speed range, which in turn protects the combustion engine. The result: optimised acceleration combined with an improved driving experience

Benefits:

Combining high performance with the advantages of hybrid and zero-emission propulsion
Improved load behaviour of the combustion engine thanks to optimised operating point
