FUEL GAS SUPPLY SYSTEM, VESSEL AND FUEL GAS SUPPLY METHOD
Document Type and Number:
Japanese Patent JP2018071475
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel gas supply system, a fuel gas supply method and a vessel adapted to prevent use of a boil-off gas liquefier from causing a fluctuation in a composition ratio of boil-off gas when pressurized boil-off gas is supplied to an engine as fuel gas.SOLUTION: A fuel gas supply system which supplies fuel gas to an engine comprises: a tank to store liquefied gas; a pressurization mechanism which pressurizes the boil-off gas vaporized from the liquefied gas and delivers the same to the engine as a fuel; a liquefier which liquefies a portion of the boil-off gas pressurized and delivered by the pressurization mechanism and returns the liquefied boil-off gas to the tank; and a control device which controls an amount of the boil-off gas flowing in the liquefier. The liquefier has recovery piping which returns gas-liquid mixed fluid, a mixture of the liquefied gas liquefied in the liquefier with the boil-off gas not liquefied therein, to a liquid phase of the liquefied gas in the tank.SELECTED DRAWING: Figure 1
