According to one embodiment of the present invention, an apparatus for reducing resistance of a moon pool comprises: a door unit opening and closing a moon pool; and a moon pool pressure control unit firing a compressed gas to the inside of the moon pool to increase internal pressure of the moon pool and prevent sea water from being introduced to the moon pool. According to the present invention, the apparatus for reducing resistance of a moon pool increases the internal pressure of the moon pool by blowing the compressed gas from the outside to the inside of the moon pool when a drill ship is moved in order to reduce damage of a hull even if a flow is generated inside the moon pool since a force, which is generated by an internal fluid, applied to the hull is reduced.

    본 발명의 일 실시예에 따른 문풀 저항 감소 장치는, 문풀을 개폐하는 도어부; 상기 문풀 내부 압력을 상승시켜 상기 문풀로의 해수 유입을 억제시키도록, 상기 문풀의 내부로 압축기체를 발사하는 문풀압력조절부를 포함하는 것을 특징으로 한다. 본 발명에 따른 문풀 저항 감소 장치는, 드릴쉽이 이동하는 중에, 압축기체를 문풀 외부에서 내부 방향으로 불어 넣는 방식으로 문풀 내의 압력을 높임으로써, 문풀 내부에 유동이 발생하더라도, 내부 유체가 선체에 가하는 힘이 줄어 선체의 파손을 감소시킬 수 있다.
