Abstract:

Provided is a gas fuel piping system that can reliably prevent gas fuel, etc. from leaking into an engine room in cases where pipes such as those for supplying the gas fuel are damaged, and inspect the pipes, etc. easily and reliably, for example. The present invention relates to a gas fuel piping system 10, which is mounted on a ship 1, for supplying gas fuel to a diesel engine 3, the system having a supply pipe 31 and a vent pipe 32 each in a double-pipe structure. The system is provided with a supply pipe 21 for sending gas fuel to the diesel engine 3, a vent pipe 22 for sending vent gas from the diesel engine 3, and a first duct 26 that covers the supply pipe 21 and a second duct 27 that covers the vent pipe 22 in an engine room 2. A supply outer tube 312 of the supply pipe 31 and a vent outer tube 322 of the vent pipe 32 extend into the first duct 26 or the second duct 27, and a rupture disk 40 is provided at the end of the supply outer tube 312 in the first duct 26 or the second duct 27.
