Document Type and Number:
Japanese Patent JP6651688
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To stably supply boil-off gas to an engine even when pressurized boil-off gas is supplied to the engine under a use condition including a case in which use of a boil-off gas liquefier causes a composition ratio of boil-off gas to fluctuate.SOLUTION: A fuel gas supply system which supplies fuel gas to an engine, comprises: a tank which stores liquefied gas; a compression mechanism which pressurizes and sends out boil-off gas vaporized from the liquefied gas in order to supply them to an engine; a gas processing device which consumes a portion of the sent out boil-off gas; and a liquefier which liquefies a portion of the sent out boil-off gas and returns them to the tank. When a composition rate of the boil-off gas in the compression mechanism and the liquefier is fluctuated, the fuel gas supply system controls a flow of the boil-off gas in a manner that sends the boil-off gas with the composition rate thereof fluctuated to the gas processing device so as to replace them in the compression mechanism and the liquefier with the boil-off gas vaporized from the liquefied gas.SELECTED DRAWING: Figure 1
