摘要

Disclosed is a liquefied gas treatment system for a ship which includes a storage tank storing LNG, and a main engine and an auxiliary engine using the LNG stored in the storage tank as a fuel. The liquefied gas treatment system includes a main BOG supply line which compresses BOG generated from the storage tank by a compressor to supply the generated BOG to the main engine as a fuel; an auxiliary BOG supply line which compresses BOG generated from the storage tank by a compressor to supply the generated BOG to the auxiliary engine as a fuel; a main LNG supply line which compresses LNG stored in the storage tank by a pump to supply the compressed LNG to the main engine as a fuel; and an auxiliary LNG supply line which compresses LNG stored in the storage tank by a pump to supply the compressed LNG to the auxiliary engine as a fuel. The fuel supplied to the main engine is compressed at 150-400 bara.
