Fuel gas supply system (FGSS) & GVU
연료가스공급장치·가스밸브유닛
The equipment that stores gas fuel and delivers it to the engines at the right pressure and temperature; the gas valve unit (GVU) is the final control-and-shutoff station before each engine.

FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.

Fuel pumps/compressors
연료 펌프/압축기The pumps or compressors raising gas fuel from tank condition to the pressure the engines need.
Design dependent · As required / design dependentView Component record →COMP-391 · Heat exchangerGas vaporizer / heater
vaporizer/heaterThe exchanger turning liquefied gas into vapour and warming it to engine inlet temperature.

gas 밸브 유닛The final valve station before each engine — filtering, regulating and able to isolate and vent the gas line instantly.
Design dependent · As required / design dependentView Component record →COMP-393 · Piping / FittingDouble-wall gas fuel piping
double-wall 배관Pipe within a pipe, with the annular space ventilated and monitored, so any gas leak is contained and detected rather than filling a space.
