摘要:
Provided is a liquefied gas treatment system for a vessel, which includes a cargo tank storing liquefied natural gas (LNG), and an engine using the LNG as fuel. The liquefied gas treatment system includes: a compressor line configured to compress boil-off gas (BOG) generated in the cargo tank by a compressor and supply the compressed BOG to the engine as fuel; a high pressure pump line configured to compress the LNG stored in the cargo tank by a pump and supply the compressed LNG to the engine as fuel; and a heat exchanger configured to liquefy a part of BOG, which is compressed by the compressor, by exchanging heat with BOG that is discharged from the cargo tank and transferred to the compressor.
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 of the ship, compressed at a high pressure, gasified, and then supplied to the high-pressure gas injection engine.
摘要:
Provided is a liquefied gas treatment method for a vessel, which is performed by a liquefied gas treatment system for the vessel including a cargo tank storing liquefied natural gas (LNG), and a main engine and a sub engine using the LNG stored in the cargo tank as fuel. The liquefied gas treatment method system includes a compressor line configured to compress BOG generated in the cargo tank by a compressor and supply the compressed BOG to the main engine and the sub engine as fuel, and a pump line configured to compress the LNG stored in the cargo tank by a pump and supply the compressed LNG to the main engine and the sub engine as fuel. In a laden condition in which an amount of the LNG stored in the cargo tank is larger than in a ballast condition, the BOG generated in the cargo tank is supplied as fuel to at least one of the main engine and the sub engine through the compressor line.
