A resistance reducing device and a drillship including the same are disclosed. According to one embodiment of the present invention, the resistance reducing device comprises: a nozzle unit spraying a fluid; and a fluid supply unit supplying the fluid to the nozzle unit. The fluid sprayed from the nozzle unit accelerates the velocity of water moving backward from below a bottom entrance of a moon-pool formed on a hull to exceed the threshold velocity of the drillship at which resistance of the moon-pool begins to decrease, thereby reducing the resistance of the moon-pool.

    저항 저감 장치 및 이를 포함하는 선박이 개시된다. 본 발명의 실시예에 따른 저항 저감 장치는 유체를 분사하는 노즐부; 및 상기 노즐부로 유체를 공급하는 유체 공급부를 포함하고, 상기 노즐부에서 분사된 유체는 선체에 형성된 문풀의 하단 입구 아래에서 후방으로 이동하는 물의 속도를 문풀 저항이 감소하기 시작하는 임계 선속을 초과하도록 가속시켜 상기 문풀 저항을 감소시킨다.
