ABSTRACT OF THE DISCLOSURE A low-speed diesel engine which is used as the propulsion engine for a passenger ship is directly coupled to a drive shaft bearing a variable-pitch propellor. The propulsion engine is designed to provide the propulsion power for the required maximal cruising speed. To provide additional power for reaching peak speed, an electric motor/generator is provided in series with the engine and supplied by the reserve power from the ship's electrical system. Electrical energy is generated by a number of medium-speed or high-speed four-stroke engines. Their power is dimensioned so that the ship's electrical system has a high excess of capacity over requirements.
