Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] figure 1 It is a schematic diagram of a gas supply system of a ship according to an embodiment of the present invention. like figure 1 As explained in , the ship's gas supply system supplies gas to the ship's high-pressure gas injection engines.

[0019] figure 1 The gas supply system includes: a gas supply line L1, which is used to supply the LNG extracted from the LNG storage tank 1 of the ship to the high-pressure gas injection engine of the ship; and a heat exchanger 3, which is installed in the middle of the gas supply line L1 In order to exchange heat between the LNG and the boil-off gas extracted from the LNG storage tank 1 .

[0020] The ship may be an LNG carrier. The LNG carrier has an LNG storage tank for storing LNG. In this case, the LNG storage tank 1 is an LNG storage tank.

[0021] In addition, the ship may be a sh...

Abstract

A fuel gas supply system of a ship is provided for supplying fuel gas to a high-pressure gas injection engine of a ship, wherein LNG is extracted from an LNG tank of the ship, compressed at a high pressure, gasified, and then supplied to the high-pressure gas injection engine.

Description

technical field [0001] The present invention relates to a gas supply system and method for a ship, and more particularly to a ship for efficiently supplying gas from a liquefied natural gas (LNG) tank to a high pressure gas injection engine in a ship Gas supply system and method. Background technique [0002] Generally, natural gas is converted into liquefied natural gas (hereinafter referred to as "LNG") at a low temperature in a liquefaction station, and then transported over a long distance to a destination by an LNG carrier. [0003] Since the liquefaction of natural gas occurs at a cryogenic temperature of -163 degrees Celsius at ambient pressure, LNG is likely to be vaporized even when the temperature of LNG is slightly higher than -163 degrees Celsius at ambient pressure. In an LNG carrier having a thermally insulated LNG storage tank, heat is continuously transferred from the outside to LNG in the LNG storage tank, the LNG is continuously vaporized, and boil-off gas...
