누출 방지 장치를 포함하는 극저온 저장탱크의 가스 돔 구조가 개시된다. 본 발명은 가스 돔 쉘의 상부에 형성되는 연결 플랜지와 그 상부에 결합되는 해치 커버 사이의 기밀이 극저온용 오-링(cryogenic O-ring)과 가스킷(gasket)에 의해 이중으로 이루어짐으로써, 선체 변형 및 열변형에 의한 가스 돔의 변형이 발생하더라도 가스 돔의 볼트 결합부에서의 가스 누출이 효과적으로 방지한다.

    Disclosed is a gas dome structure for a cryogenic storage tank including a leakage preventing device. The gas dome structure for a cryogenic storage tank including the leakage preventing device allows airtightness between a connecting flange formed on an upper portion of a gas dome shell and a hatch cover coupled to an upper portion thereof to be doubly implemented by a cryogenic O-ring and a gasket, thereby effectively preventing gas leakages in a bolt coupling part of a gas dome even when deformation of the gas dome caused by hull deformation and thermal deformation is generated.
