To suppress fuel gas flowing in a filling hose from being warmed up by an outside air temperature when filling the fuel gas into a fuel tank of a vessel.SOLUTION: A fuel gas filling system 1 includes: a fuel gas filling device 6 constituted by including a gas supply pipeline 8 which is disposed in a body 7 and to which fuel gas stored in a gas accumulator 5 is supplied, a filling hose 9 which connects the gas supply pipeline 8 and a fuel tank 52 of a vessel 51, and a cooler 13 for cooling fuel gas flowing in the gas supply pipeline 8; and a floating pier 2 which is provided with a fuel gas filling device 6 and to which the vessel 51 is moored. The floating pier 2 and the vessel 51 integrally and vertically move according to displacement of a sea surface A caused by ebb and flow of tide level. Therefore, the filling hose 9 for connecting between the gas supply pipeline 8 and the fuel tank 52 of the vessel 51 can be set to a required minimum length dimension and hydrogen gas flowing in the filling hose 9 can be suppressed from being warmed up by an outside air temperature.SELECTED DRAWING: Figure 1

    【課題】船舶の燃料タンクに燃料ガスを充填するときに、充填ホースを流れる燃料ガスが外気温によって暖められるのを抑える。【解決手段】燃料ガス充填システム1は、筐体7内に配設され、ガス蓄圧器5に貯留された燃料ガスが供給されるガス供給管路8と、ガス供給管路8と船舶51の燃料タンク52との間を接続する充填ホース9と、ガス供給管路8を流れる燃料ガスを冷却する冷却器13とを含んで構成された燃料ガス充填装置6と、燃料ガス充填装置6が設けられ船舶51が係留される浮桟橋2と、を備える。浮桟橋2と船舶51とは、潮位の干満による海面Aの変位に応じて一体的に上下動するため、ガス供給管路8と船舶51の燃料タンク52との間を接続する充填ホース9を、必要最小限の長さ寸法に設定することができ、充填ホース9を流れる水素ガスが外気温によって暖められるのを抑えることができる。【選択図】図1
