According to one embodiment of the present invention, a moon pool device comprises: an expansion unit of which an internal volume is increased or decreased in accordance with an inflow and an outflow of an internal gas to open or close a moon pool; and a volume control unit of which one end is fixated to one side of the expansion unit and the other end is fixated to the moon pool to control the volume of the expansion unit. According to the present invention, the moon pool device reduces the amount of a fluid inside the moon pool by filling a space inside the moon pool while a drill ship or a semi-submersible offshore structure are moved in order to prevent movement of the inside of the moon pool, and resistance can be decreased since a force, that a fluid is applied to a hull or the inside of a column, is decreased.

    본 발명의 일 실시예에 따른 문풀 장치는, 내부에 기체가 유출입됨에 따라 그 내부 부피가 가감되어, 상기 문풀을 개방 또는 밀폐하는 확장부; 및 일단이 상기 확장부의 일측에 고정되고 타단이 상기 문풀에 고정되어, 상기 확장부의 부피를 제어하는 부피조정부를 포함하는 것을 특징으로 한다. 본 발명에 따른 문풀 장치는, 드릴쉽이나 반잠수식 해양구조물이 이동하는 중에, 문풀 내부 공간을 채워 문풀 내의 유체의 양을 줄임으로써, 문풀 내부에 유동이 발생하는 것을 방지하고, 유체가 선체 또는 컬럼 내부를 가하는 힘이 줄어 저항이 감소할 수 있다.
