FUEL GAS SUPPLY SYSTEM AND METHOD OF A SHIP

摘要

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 (1) of the ship, compressed at a high pressure via a first pump (2) and a second pump (4), gasified, and then supplied to the high-pressure gas injection engine. The second pump is a high pressure pump which pressurizes the extracted LNG to meet the fuel gas pressure requirements of for the high-pressure gas injection engine, and a pressure control valve is installed in parallel with the second pump (4) in the fuel supply line (L1).
