The present invention provides an apparatus for reducing movement of an offshore structure, to maintain a stable floating state. According to the present invention, the apparatus for reducing movement of an offshore structure comprises: a pair of bow tanks storing fluid therein; a pair of stern tanks storing fluid therein; a bow connection pipe connecting the bow tanks and connected to a bow moving pump generating pumping force for moving the fluid between the bow tanks; a stern connection pipe connecting the stern tanks and connected to a stern moving pump generating pumping force for moving the fluid between the stern tanks; a left connection pipe connected to the bow and stern tanks disposed on the lower side of the offshore structure; a right connection pipe connected to connect the bow and stern tanks disposed on the right side of the offshore structure; a position measurement unit installed in the offshore structure and measuring the slope caused by the rolling and pitching motions of the sea around the offshore structure; and a fluid storage control unit connected to the position measurement unit, the bow and stern moving pumps, and the left and right moving pumps and operating the bow and stern moving pumps and the left and right moving pumps in accordance with the slope of the offshore structure measured by the position measurement unit to reduce the rolling and pitching motions of the offshore structure while adjusting the amount of fluid stored in each of the bow and stern tanks.

    본 발명은, 내부에 유체가 저장된 한 쌍의 선수탱크, 내부에 유체가 저장된 한 쌍의 선미탱크, 한 쌍의 상기 선수탱크를 연결하도록 설치하며, 한 쌍의 선수탱크 사이에서 유체의 이동을 위한 핌핑력을 발생시키는 선수이동펌프를 연결 구비하는 선수연결관로, 한 쌍의 상기 선미탱크를 연결하도록 설치하며, 한 쌍의 선미탱크 사이에서 유체의 이동을 위한 핌핑력을 발생시키는 선미이동펌프를 연결 구비하는 선미연결관로, 해양구조물의 좌측에 배치된 상기 선수탱크 및 선미탱크를 연결하도록 설치하는 좌측연결관로, 해양구조물의 우측에 배치된 선수탱크 및 선미탱크를 연결하도록 설치하는 우측연결관로, 해양구조물에 설치하며, 해양구조물의 해상에서 롤링 및 피칭운동을 통한 기울기를 측정하는 위치측정부, 위치측정부와 선수이동펌프와 선미이동펌프와 좌측이동펌프 및 우측이동펌프와 연결되게 설치하며, 위치측정부에서 측정된 해양구조물의 기울기에 따라 선수이동펌프와 선미이동펌프와 좌측이동펌프 및 우측이동펌프를 작동시켜, 각각의 선수탱크와 선미탱크에 저장되는 유체량을 조절하면서 해양구조물의 롤링 및 피칭 운동을 감소시키는 유체저장제어부를 포함하는 해양구조물용 동요감소장치를 제공한다.
