The invention discloses a dual-fuel propulsion device for a ship. The dual-fuel propulsion device comprises a fuel supply system, a combustion injection system, a dual-fuel engine and an inflator pump, the fuel supply system comprises an LNG supply system and a diesel supply system, an output source of the diesel supply system is the diesel tank, and an output source of the LNG supply system is the fuel storage tank; the LNG supply system and the diesel oil supply system supply fuel to the dual-fuel engine through valve pipelines. The combustion injection system is used for controlling opening or closing of a valve in the valve pipeline; the inflator pump is arranged on the valve pipeline between the fuel supply system and the dual-fuel engine, a pressure gauge and a display are arranged on the inflator pump, the display is electrically connected with the pressure sensor, and the display is used for displaying a pressure-time oscillogram of the pressure sensor; the device solves the problem of fuel waste caused by pipeline leakage.
