Abstract

Disclosed is a fuel gas supply system (FGSS) of a vessel, which supplies natural gas to an engine as a fuel. The FGSS of the vessel includes: a storage tank in which a liquid cargo is stored; a vent mast connected to the storage tank; a fuel pipe line connected to the engine to supply the fuel; and a vent line connected to the fuel pipe line, wherein the vent line is connected to the vent mast.

Description

technical field [0001] The present invention relates to a gas supply system of a ship, and more particularly, to a gas supply system of a ship having a discharge line through which natural gas in the fuel supply line of the ship is discharged. Background technique [0002] Liquefied gases such as liquefied natural gas (LNG) and liquefied petroleum gas (LPG) are obtained by cooling natural gas or petroleum gas to cryogenic temperatures (approximately -163° C. in the case of liquefied natural gas). As a result, liquefied gas has a greatly reduced volume compared to its gaseous state, making it ideal for long-distance transportation by sea. [0003] A liquefied gas carrier, such as an LNG carrier, is used to transport the liquefied gas by sea to a ground destination and unload the liquefied gas. To this end, liquefied gas carriers include cargo compartments (commonly referred to as "cargo compartments") that can withstand the cryogenic temperatures of liquefied gas. In additi...
