摘要
A power-turbine control unit calculates, on the basis of inboard required power and a load on a main engine (22), a degree-of-opening of a power-turbine control valve (B) that controls a flow volume of the exhaust gas to be supplied to a power turbine (23) from the main engine (22) as a feedforward degree-of-opening and outputs the feedforward degree-of-opening to a power-turbine control valve (B). A fuel-injection control unit calculates a fuel injection amount for the main engine (22) that corresponds to an output of a shaft generator motor (35) during the motor operation as a converted fuel-injection amount and subtracts the converted fuel-injection amount from the fuel injection amount to be supplied to the main engine (22).
