Abstract (en)

[origin: EP2236409A2] There is provided an electric propulsion system for a ship in which the cargo capacity of the ship is enhanced while the ship speed of the dead slow or less can be controlled. The electric propulsion system includes a variable speed engine (2), a synchronous generator (3) that generates electricity by the variable speed engine, an induction motor (6) that is connected to the synchronous generator, and a fixed-pitch propeller (7) that is driven by the induction motor.
