Fuel Gas Supply System

System configuration

Fuel Gas Supply System(FGSS) is used to supply a fuel gas to ME-GI engine. The high pressure LNG is being supplied by HP liquefied natural gas pump and then, vaporized to natural gas. Glycol Water is generally used to heat-source for vaporizing liquefied natural gas, and Glycol Heating System is accompanied including Glycol Tank and Glycol Pump.

Main fuel supply system package unit for both high pressure 2 stroke engine and low pressure 4 stroke generator engines
