The present invention relates to a drilling marine structure including an apparatus for restraining flow inside a moon pool, and a drilling marine structure including the same. More specifically, a first flow reduction member of a porous structure is installed on a lower front surface of a BOP guide portion (guide plate) of a BOP trolley, and a second flow reduction member of a porous structure is installed on a lower rear surface of the BOP guide portion, thereby blocking an overflow phenomenon in advance where a wave inside the moon pool crashes an outer wall, on the side of a stern of a ship, of a recess, vertically rises, and returns back to a main deck and, further, securing safety of a worker passing through the main deck near the recess on the side of the stern of the ship.

    본 발명은 문풀 내부 유동억제 장치 및 그 장치를 구비하는 시추 해양구조물에 관한 것으로, BOP 트롤리의 BOP 가이드 부(가이드 플레이트) 하부 전면에 다공 구조의 제1 유동 저감 부재가 설치되고, BOP 가이드 부의 하부 후면에 다공 구조의 제2 유동 저감 부재가 설치됨으로써, 문풀 내부의 파도가 리세스의 선미 측 외벽에 부딪혀서 수직 상승하여 메인 데크로 올라오는 오버플로우 현상을 사전에 차단하여 선미 측 리세스 근처의 메인 데크를 통행하는 작업자의 안전을 확보할 수 있다.
