PROBLEM TO BE SOLVED: To sufficiently cool excess gas even when there is much the excess gas.SOLUTION: A marine vessel comprises: a gas consumer for propulsion; a tank for accumulating LNG; an air supply line for introducing the BOG generated in the tank to a compressor; a supply line for introducing the BOG discharged from the compressor to the gas consumer; a return line for returning the excess gas to the tank from the supply line and having an expansion device; a service heat exchanger for cooling the excess gas flowing through the return line on the upstream of the expansion device; an emergency heat exchanger for cooling the excess gas flowing through the return line between the service heat exchanger and the expansion device; and a liquid supply line for introducing the LNG discharged from a pump disposed within the tank to a forced carburetor. The emergency heat exchanger is for heat exchange between the excess gas cooled by the service heat exchanger and the LNG flowing through the liquid supply line via a latent heat storage material. The latent heat storage material is cooled and solidified by the LNG; and heated and melted by the excess gas at a prescribed temperature or higher.SELECTED DRAWING: Figure 1
【課題】余剰ガスが多い場合でも余剰ガスを十分に冷却できるようにする。【解決手段】船舶は、推進用のガス消費器と、ＬＮＧを貯留するタンクと、タンク内で発生するＢＯＧを圧縮機へ導く送気ラインと、圧縮機から吐出されるＢＯＧをガス消費器へ導く供給ラインと、供給ラインから余剰ガスをタンクへ戻す、膨張装置が設けられた返送ラインと、膨張装置の上流側で返送ラインに流れる余剰ガスを冷却するための常用熱交換器と、常用熱交換器と膨張装置の間で返送ラインに流れる余剰ガスを冷却するための非常用熱交換器と、タンク内に配置されたポンプから吐出されるＬＮＧを強制気化器へ導く送液ラインと、を備え、非常用熱交換器は、常用熱交換器で冷却された余剰ガスと送液ラインに流れるＬＮＧとの間で潜熱蓄熱材を介して熱交換を行うものであり、潜熱蓄熱材は、ＬＮＧにより冷却されて凝固し、所定温度以上の余剰ガスにより加熱されて融解する。【選択図】図１
