A device for reducing rolling of a ship comprises: a plurality of bilge keel blocks which are continuously installed from a bow to a stern of a ship. Each bilge keel block comprises: an insertion groove which leads in from an external plate of the ship to the inside; a moving unit which is coupled with the insertion groove and installed in the ship, and has a driving motor, a rotating shaft which is bidirectionally rotated by the driving motor, and a moving object which is coupled with the rotating shaft by a screw and is spirally rotated during rotation of the rotating shaft to reciprocate along with the rotating shaft; and a bilge keel which is coupled with the moving object to be inserted into the inside of the insertion groove or protrude toward the outside of the insertion groove by the reciprocating motion. Therefore, a simple and efficient structure capable of movement according to a sea condition is realized and resistance reduction and rolling attenuation performance are simultaneously improved.

    선박의 횡동요 저감장치는 선체의 선수에서 선미 방향으로 연속적으로 장착된 복수의 빌지 킬 블록을 포함한다. 각 빌지 킬 블록은 선체 외판에서 내측 방향으로 인입 형성된 삽입 홈; 삽입 홈에 결합되어 선체 내에 설치되며, 구동 모터, 구동 모터에 의해 양방향 회전하는 회전축, 및 회전축과 나사 결합하고 회전축의 회전 시에 나선 회전하여 회전축을 따라 왕복 운동하는 이동체를 포함하는 이동 유닛; 및 이동체에 결합하여 왕복 운동에 따라 삽입 홈의 내측으로 삽입되거나 삽입 홈의 외측으로 돌출되는 빌지 킬을 포함한다. 이에 따라, 해상 상태에 따라 가동이 가능한 단순하고 효율적인 구조를 구현할 수 있고 운항 시의 저항감소 및 횡동요 감쇠성능 향상을 동시에 이룰 수 있게 된다.
