The present invention relates to a device for preventing shaking motion of an offshore structure. The device for preventing shaking motion of an offshore structure comprises: a water plane varying mechanism which is installed to surround a side wall of an offshore structure, and varies a moment of inertia of a water plane area or a water plane of the offshore structure; and a drive unit which is connected to the water plane varying mechanism, is disposed on the offshore structure, and drives the water plane varying mechanism. The device for preventing shaking motion of the offshore structure in accordance with the present invention is installed with the water plane varying mechanism of a vertical movement type, a variable wing type, a volume changing type, or a fixed type to surround the side wall of the offshore structure in order to adequately vary the moment of inertia of the water plane area or the water plane of the offshore structure according to an external force generated by an external environment, thereby avoiding a resonant frequency of the external force through a change in restoring force, and attenuating and correcting all shaking motion including rolling, pitching, and heaving, and improving work efficiency and safety.
본 발명은 해양구조물의 동요 방지장치에 관한 것으로서, 해양구조물의 측벽을 둘러싸도록 설치되며, 상기 해양구조물의 수선면적 또는 수선면의 관성모멘트를 가변시키는 수선면 가변기구; 및 상기 수선면 가변기구와 연결되어 상기 해양구조물에 구비되며, 상기 수선면 가변기구를 구동시키는 구동부를 포함하는 것을 특징으로 한다. 본 발명에 따른 해양구조물의 동요 방지장치는, 외부 환경에 의해 발생하는 외력에 따라 해양구조물의 수선면적 또는 수선면의 관성모멘트를 적절하게 가변시킬 수 있도록, 상하이동식, 가변익식, 볼륨변화식 또는 고정식의 수선면 가변기구를 해양구조물의 측벽을 둘러싸도록 설치함으로써, 복원력 변화를 통한 외력의 공진주파수를 회피할 수 있어, 횡동요, 종동요, 상하동요 등의 모든 동요를 감쇠 보정할 수 있어, 작업효율과 안전성을 향상시킬 수 있다.
