The present invention relates to a gas supply system and a ship having the same. According to one aspect of the present invention, the gas supply system comprises: a type B or a membrane-type storage tank; a plurality of boosting tanks having a pressure build-up unit (PBU); and a buffer tank placed between the storage tank and the boosting tanks. Some of the plurality of boosting tanks are pressurized by the PBU to supply fuel to an engine, and at least some of the remaining boosting tanks are on standby in a state of being pressurized by the PBU. The buffer tank transfers the fuel supplied from the storage tank to the boosting tanks without pumping the gas by a fuel pump, receives high-temperature gas generated in the boosting tanks which have stopped supplying the fuel, and makes the internal pressure of the buffer tank and the boosting tanks in a state to be able to transfer fuel from the buffer tank to the boosting tanks. The gas supply system can effectively increase the pressure in the fuel tank to improve the gas supply efficiency from the fuel tank to the demand. 본 발명은 가스 공급 시스템 및 이를 구비한 선박에 관한 것으로서, 본 발명의 일 측면에 따른 가스 공급 시스템은, B 타입 또는 멤브레인형의 저장탱크; PBU(pressure build-up unit)를 구비한 복수 개의 부스팅 탱크; 및 상기 저장탱크와 상기 부스팅 탱크 사이에 마련된 버퍼탱크를 포함하며, 상기 복수 개의 부스팅 탱크는, 일부가 상기 PBU에 의해 가압되어 엔진으로 연료를 공급하고, 나머지 중 적어도 일부가 상기 PBU에 의해 가압된 상태로 대기하며, 상기 버퍼탱크는, 상기 저장탱크로부터 공급된 연료를 연료 펌프에 의한 펌핑 없이 부스팅 탱크로 전달하며, 연료 공급을 중단한 상기 부스팅 탱크에서 발생하는 고온가스를 전달받아, 상기 버퍼탱크와 상기 부스팅 탱크의 내압을 상기 버퍼탱크로부터 상기 부스팅 탱크로 연료 전달이 가능한 상태로 만드는 것을 특징으로 한다.
