FUEL SUPPLY APPARATUS OF LIQUEFIED GAS CARRIER AND FUEL SUPPLY METHOD THEREOF
First Claim
1. A fuel supply apparatus of a liquefied gas carrier, comprising:
- a compressor for compressing gas fuel into a high pressure;
a compressed gas storage tank being filled with the compressed high-pressure gas fuel, for storing the gas fuel; and
a decompressor for decompressing the high-pressure gas fuel drawn from the compressed gas storage tank into a pressure to be used in a propulsion system, to supply fuel to the propulsion system.

Abstract
A fuel supply apparatus of a liquefied gas carrier includes: a compressor for compressing gas fuel into a high pressure; a compressed gas storage tank being filled with the compressed high-pressure gas fuel, for storing the gas fuel; and a decompressor for decompressing the high-pressure gas fuel drawn from the compressed gas storage tank into a pressure suitable to be used in a propulsion system, to supply fuel to the propulsion system. The gas fuel is at least one of a natural boiled-off gas which is naturally evaporated in the cargo tank, a forced boiled-off gas which is artificially evaporated, and a gas additionally supplied for the use of fuel. Further, the compressor is a multistage high-pressure compressor and the decompressor is a multistage decompressor.
