System for supplying liquefied natural gas fuel

摘要

A system (1) for supplying LNG fuel is disclosed. The system includes a fuel supplying line connected from an LNG storage tank (10) to a high pressure engine (20) and a low pressure engine (30) , respectively, a pump (50) formed on the fuel supplying line, and configured to pressurize LNG outputted from the LNG storage tank (10) to high pressure, a first heat exchanger (71) formed on the fuel supplying line between the high pressure engine (30) and the pump (50), and configured to heat the LNG supplied from the pump (50), a second heat exchanger (72) formed on the fuel supplying line between the low pressure engine (30) and the LNG storage tank (10), and configured to evaporate the LNG in a liquid state supplied from the LNG storage tank (10) and a heat source supplying line configured to supply heat to the LNG by supplying glycol water to the first heat exchanger (71) and the second heat exchanger (72).
