<p>The objective of the present invention is to provide a ship that protects an electric motor without using a frequency converter and that is capable of propulsion by means of the combined output of the output from an internal combustion engine and the output from the electric motor. The objective of the present invention is also to provide a low-cost ship that does not use a frequency converter. In the ship (1), which combines the output (We) from a main engine (2) that is an internal combustion engine and the output (Wm) from an electric motor (4) and transmits the result to a variable pitch propeller (7), a target output (Wmt) is set for the electric motor (4), the target rotational velocity (Vet) of the rotational velocity (Ve) of the main engine (2) is controlled in a manner so that the output (Wm) from the electric motor (4) is maintained at the target output (Wmt), and thus the load sharing proportion of the main engine (2) and the electric motor (4) is caused to vary.</p> |
