PROBLEM TO BE SOLVED: To provide a liquefied gas supply device for a ship, capable of gasifying LNG, supplying the liquefied LNG to a gas fuel engine, and being stably operated.SOLUTION: A liquefied gas supply device comprises: a liquefied gas storage tank 101; a tank boosting vaporizer 107; a supply vaporizer 102; a circulation circuit 200 which is provided with a heater 307, and an equipped pump 301, and circulates cooling water between both the vaporizers and an engine; a cooling bypass passage 201 which is equipped with a cooler 308 and is provided on the circuit; and an electric pump 302 which is provided on a bypass passage 202 bypassing the equipped pump, and transfers the cooling water in circulation during stop of the equipped pump. The inside of the tank is maintained at a predetermined pressure and LNG is exactly supplied to the supply vaporizer, and gas fuel can be exactly generated by effectively utilizing heat of the cooling water. A sufficient amount of gas can be supplied to the engine in response to a high-load operation.

    【課題】LNGをガス化してガス燃料エンジンに供給し、安定的に運転できる船舶用の液化ガス供給装置を提供する。【解決手段】液化ガス供給装置は、液化ガス貯蔵タンク101 と、タンク昇圧気化器107 と、供給気化器102 と、ヒータ307 と機付ポンプ301 が設けられて冷却水を両気化器とエンジンの間で循環する循環路200 と、クーラ308 を備え循環路に設けられた冷却パイパス路201 と、機付ポンプを迂回するバイパス路202 に設けられて機付ポンプの停止中に冷却水を循環移送する電動ポンプ302 を備える。タンク内を所定圧に維持してLNGを供給気化器に的確に供給し、冷却水の熱を有効利用してガス燃料を的確に生成できる。高負荷運転に対応して十分なガス量をエンジンに供給できる。【選択図】図1
