The present disclosure relates to an LPG ship propulsion system characterized in that fuels are supplied simultaneously to an engine for propulsion and an engine for power generation and thus, a system thereof can be simplified, waste heat generated from a power generator or the like is supplied for heat exchange such that there is no need for a pipe to supply glycol water used for heat exchange and other facilities for the same, thereby being economical. In addition, a structure of the LPG ship propulsion system can be improved through simplification of a line. The LPG ship propulsion system according to an embodiment of the present disclosure comprises: a bunkering station unit provided to supply LPG from loading, which is a production site of liquefied petroleum gas, to a carrier ship; an LPG fuel supply tank unit provided on the carrier ship, receiving the LPG from the bunkering station unit, and storing the LPG therein; a fuel gas supply tank unit receiving the LPG from the LPG fuel supply tank unit and vaporizing the received LPG; and an LPG gas valve unit receiving the vaporized LPG from the fuel gas supply tank, storing the received LPG, and delivering the stored LPG to a gas turbine of the carrier ship.

    본 개시는 추진용 엔진과 발전용 엔진에 연료를 동시에 공급하여 시스템의 단순화가 가능하고, 발전기 등으로부터 발생된 폐열을 공급하여 열교환하도록 함으로써 열교환을 위해 사용되는 글리콜 워터를 공급하기 위한 배관 및 이를 위한 제반시설이 필요하지 않아 경제적이면서 라인 단순화를 통한 구조의 개선이 가능한 장점을 갖는 LPG 선박 추진 시스템에 관한 것이다. 본 개시의 실시예에 따른 LPG 선박 추진 시스템은, 액화석유가스의 생산지인 로딩으로부터 LPG를 운반선에 공급하도록 구비된 벙커링 스테이션부와, 상기 운반선에 구비되며 상기 벙커링 스테이션부로부터 상기 LPG를 공급받아 저장하는 LPG 연료 공급 탱크부와, 상기 LPG 연료 공급 탱크부로부터 상기 LPG를 공급받아 기화시키는 연료 가스 공급 탱크부 및 상기 연료 가스 공급 탱크부로부터 기화된 상기 LPG를 공급받아 저장하고 상기 운반선의 가스터빈으로 전달되게 하는 LPG 가스 밸브 유닛부를 포함하여 이루어지는 것을 특징으로 한다.
