HYBRID SHIP PROPULSION SYSTEM

摘要

The invention relates to a hybrid propulsion system that comprises a main diesel engine (17) for driving the marine turbine (8) and an electric motor (15). The electric motor (15) has a nominal output that constitutes at least 20 % of the nominal output of the main diesel engine (17). The electric motor (15) remains continuously switched on and maintains, together with a variable-pitch propeller (7), the main diesel engine (17) at a favorable operating point. The combination of the main diesel engine (17) and the electric motor (17) also allows for a more economical design or operation of the propulsion system.
