Title:
船舶推進装置、船舶、及び船舶推進方法
Document Type and Number:
Japanese Patent JP5571151
Kind Code:
B2
Abstract:
A ship (1) includes a gas turbine (14) that is driven by exhaust gas from a main engine (12) which is provided with a turbocharger (22) and drives a propulsion propeller (29); a steam turbine (18) that is driven by steam generated by the exhaust gas; ship equipment (44) that operates as a result of being supplied with power generated by a turbine generator (20); and a power-assist motor (46) that is driven as a result of being supplied with power generated by the turbine generator (20) and that assists the main engine (12). A ship propulsion device (10) drives the power-assist motor (46) using a surplus power amount that is the difference between the amount of power generated by the turbine generator (20) and the amount of power required by the ship equipment (44), and reduces the bleed exhaust gas flow of exhaust gas to the gas turbine (14) when the power consumption amount of the power-assist motor (46) arrives at a preset power amount and the amount of generated power exceeds the total of the power consumption amount and the required power amount of the ship equipment (44).
