Zusammenfassung:	PROBLEM TO BE SOLVED: To stably supply fuel gas in correspondence with an engine load even when a composition ratio of composition components in the fuel gas varies.SOLUTION: A system for supplying fuel gas includes a plurality of gas compression mechanisms provided in series so as to compress the fuel gas and to make the fuel gas flow from a supply source side of the fuel gas to a propulsion engine side. The gas compression mechanisms respectively include a gas compressor, a suction snapper and a delivery snapper attached to the gas compressor, and a heat exchanger provided in the downstream side of the delivery snapper. A heat exchanger of a first gas compression mechanism of the gas compression mechanisms adjusts a temperature of the fuel gas in a gas output end of the heat exchanger by adjusting cooling performance in accordance with a composition ratio of composition components in the fuel gas.SELECTED DRAWING: Figure 1 【課題】燃料ガス中の組成成分の組成比率が変化しても、エンジンの負荷に応じて安定した燃料ガスの供給を行う。【解決手段】燃料ガス供給システムは、燃料ガスを圧縮して前記燃料ガスの供給源の側から推進エンジンの側に流す、直列に設けられた複数のガス圧縮機構を備える。前記ガス圧縮機構のそれぞれは、ガスコンプレッサと、前記ガスコンプレッサに付随する吸引スナッパ及び吐出スナッパと、前記吐出スナッパより下流側に設けられた熱交換器と、を備える。前記複数のガス圧縮機構のうちの第１ガス圧縮機構の熱交換器は、前記燃料ガス中の組成成分の組成比率に応じて、冷却能を調整することにより、前記熱交換器のガス出力端における前記燃料ガスの温度を調整する。【選択図】図１
