SHIP
Document Type and Number:
WIPO Patent Application WO/2019/049790
Kind Code:
A1
Abstract:
A ship that comprises: a fuel tank that stores LPG; a propulsion engine that uses the LPG as fuel; a fuel supply line that supplies LPG from the fuel tank to the engine; a pump that is provided to the fuel supply line; a fuel recovery line that recovers unused LPG from the engine to the fuel tank; a pressure regulation valve that is provided to the fuel recovery line; a control device that controls the pump and the pressure regulation valve; and a manometer that detects the pressure of the LPG supplied to the engine. The relationship between a target opening angle for the pressure regulation valve and the fuel consumption of the engine is prestored at the control device. The control device controls the pressure regulation valve such that the pressure detected by the manometer is at a set value and controls the pump such that the opening angle of the pressure regulation valve is the target opening angle, which corresponds to the actual fuel consumption of the engine.
