Disclosed is a seawater supply system for a ship. According to the present invention, the seawater supply system for a ship includes: a regasification unit provided on a ship and regasifying LNG; a seawater pump supplying seawater for supplying thermal energy to the regasification unit; a ballast pump provided on the ship and supplying the seawater to a ballast tank in a ship; and a seawater supply line supplying the seawater from the ballast pump to the regasification unit. The present invention utilizes a ballast system preinstalled in the ship and additionally supplies the seawater to the regasification unit, thereby reducing the number and capacity of a large pump installed to supply the seawater to the regasification unit.

    선박의 해수 공급 시스템이 개시된다. 본 발명에 따른 선박의 해수 공급 시스템은, 선박에 마련되며 LNG를 재기화시키는 재기화부; 상기 재기화부에 열에너지를 공급하기 위한 해수를 공급하는 해수 펌프; 상기 선박에 마련되며 선내의 밸러스트탱크(ballast tank)로 해수를 공급하는 밸러스트 펌프; 및 상기 밸러스트 펌프로부터 상기 재기화부로 해수를 공급하는 해수공급라인;을 포함한다. 본 발명은 선박에 기설치된 밸러스트 시스템을 활용하여 재기화부로 해수를 추가적으로 공급함으로써, 재기화부로 해수를 공급하기 위해 설치되는 대형 펌프의 대수 및 용량을 절감한다.
