Abstract
For the development of new, efficient and alternative powertrains an increasing electrification of its components is key focus. MAN Engines as part of MAN Truck & Bus SE is currently developing a marine propulsion solution with incorporated energy management system, that extends the proven diesel technology with an electric machine. Since the MAN Marine Hybrid System for marine applications provides a higher variance than conventional powertrain setups, the individual adaption for expected areas of use and load profiles plays a major role in the optimization process. Non-disruptive changes of operation modes give versatile challenges when developing and calibrating this system. Amongst others the high requirements in comfort and improved performance of the dynamic system behaviour will be described and characterized. Hereby the focus will be on operation mode transitions that could already be measured in the test bench setup. Supported by investigations on the elaborate test bench setup an evaluation of efficiency aspects gives a first impression on the economic prospects of the MAN Marine Hybrid System for the use in commercial as well as pleasure marine applications.

Notes
- 1.
As of 2015.
- 2.
The displayed exemplary propeller curve uses a coefficient of 2.5 and varies dependent on the ship properties.
- 3.
While system actions remain similar, the transition times can differ due start up phases of the auxiliary generators, see also sect. 3.2.
- 4.
Clutch K0 is the electromagnetic clutch between the diesel engine and the electric motor.
- 5.
The inner torque of the diesel engine is plotted, the additional torque needed to overcome inner friction and heat losses explains the discrepancy between the diesel engine and electric machine torque values.
- 6.
Final energy is the physical appearance of the energy that the end user receives (e.g. diesel, electricity,…).
