Disclosed is a passing hole structure for a pressurized type cryogenic storage tank. The passing hole structure for a pressurized type cryogenic storage tank of the present invention includes: a storage tank in which cryogenic liquefied gas is stored; an inner shell installed to penetrate into the storage tank to be extended to an upper side of a deck; an outer shell of which a lower end is supported by the deck and which is installed to surround the inner shell so that a space is formed between the inner shell and the outer shell; a connector flange installed to protrude in an outer direction of the inner shell, connected to an upper end of the outer shell and connecting the inner shell and the outer shell; and at least a plurality of brackets installed between the outer shell and the deck to increase a support structure of the outer shell, thereby being structurally reinforced. Thus, the passing hole structure for a pressurized type cryogenic storage tank prevents deformation of or damage to the storage tank from being generated by increased pressure in the tank by BOG.

    가압형 극저온 저장탱크의 패싱 홀 구조가 개시된다. 본 발명은 극저온의 액화가스가 저장되는 저장탱크; 저장탱크를 관통하여 데크 상측까지 연장되도록 설치되는 내부 쉘; 데크에 의해 하단이 지지되며 내부 쉘과의 사이에 공간이 형성되도록 내부 쉘을 둘러싸도록 설치되는 외부 쉘; 내부 내부 쉘의 외측 방향으로 돌출되게 설치되며 외부 쉘의 상단과 연결되어, 내부 쉘과 외부 쉘을 연결하는 커넥터 플랜지; 및 외부 쉘과 데크 사이에 설치되어 외부 쉘의 지지 구조를 증대시키는 적어도 다수의 브라켓을 포함하여 구조적으로 보강된 가압형 극저온 저장탱크의 패싱 홀 구조를 제공함으로써, BOG에 의해 탱크 내 증가된 압력에 의해 저장탱크의 변형 또는 파손이 발생하는 것을 방지한다.
