SYSTEM FOR PROCESSING LIQUEFIED GAS ON VESSEL

摘要

Disclosed is a system for treating liquefied gas on a vessel, the system having a storage tank for storing liquefied natural gas, and an engine using the liquefied natural gas as fuel. The system for treating liquefied gas comprises: a compressor line for supplying, to the engine as fuel, boil-off gas generated in the storage tank and compressed by a compressor; a high-pressure pump line for supplying, to the engine as fuel, liquefied natural gas stored in the storage tank and compressed by a pump; and a heat exchanger for transferring heat between a part of the boil-off gas, from among the boil-off gas compressed by the compressor, and the boil-off gas discharged from the storage tank and transported to the compressor, so as to liquefy same.
