The present invention relates to a double pipe purging system for ammonia fuel propulsion ships and a method thereof, and more specifically to the double pipe purging system and method for ammonia fuel propulsion ships, recovering and reusing liquid ammonia as fuel while purging with inert gas if liquid ammonia leaks in an annular space of a fuel supply line and a fuel return line made in a double-pipe, and processing leaked ammonia by vaporizing and discharging remaining liquid ammonia that cannot be recovered. The double pipe purging system for ammonia fuel propulsion ships comprises: an ammonia tank; a fuel preparation tank; a fuel supply line; a fuel return line; a first leak detection sensor; a second leak detection sensor; an inert gas supply line; a drain part; and a vent part.

    본 발명은 암모니아 연료 추진 선박의 이중관 퍼징시스템 및 방법에 관한 것으로, 더욱 상세하게는 이중관으로 된 연료공급라인 및 연료리턴라인의 환체공간(annular space)에 액상 암모니아의 누설이 발생한 경우 불활성기체로 퍼징하면서, 액상 암모니아는 회수하여 연료로 다시 사용하고, 회수되지 못하고 남아있는 액상 암모니아는 기화시켜 배출해 누설된 암모니아를 처리하는 암모니아 연료 추진 선박의 이중관 퍼징시스템 및 방법에 관한 것이다.
