The invention discloses a wave compensation ship and a wave compensation method thereof. The wave compensation ship comprises a lower-layer ship body, an upper-layer carrier and active waves. The lower-layer ship body is a main ship body moving in water, and all infrastructures without wave compensation are installed on the upper portions of the head end and the tail end of the lower-layer ship body. The upper-layer carrier is a bearing part for personnel and equipment easily affected by swing and is a whole body needing wave motion compensation; the active wave compensation system is a connecting part between the upper-layer carrier and the lower-layer ship body and is composed of an oil cylinder or electric cylinder assembly capable of generating compensation motion, a measurement and control device, a hydraulic system, an electric system, a connecting piece, an auxiliary device and the like; when wave compensation is carried out, the attitude sensor measures rolling, pitching and heaving motion attitude values of the ship body and transmits the values to the motion controller in real time, the motion controller calculates rolling, pitching and heaving compensation values according to an inverse solution algorithm of wave compensation values and controls the oil cylinders to act according to the compensation values, and three-degree-of-freedom compensation of the upper carrier is achieved.
本发明公开了一种波浪补偿船舶及其波浪补偿方法,波浪补偿船舶包括下层船体、上层载体和主动波浪;下层船体为水中运动主船体,其头尾端上部装有不需要波浪补偿的所有基础设施;上层载体为人员和易受摇摆影响设备的承载部分,为需进行波浪运动补偿的整体;主动波浪补偿系统为上层载体与下层船体之间的连接部分,由能产生补偿运动的油缸或电动缸组件与测控装置、液动系统、电动系统、联接件、辅助装置等组成;进行波浪补偿时,姿态传感器测量船体的横摇、纵摇、升沉的运动姿态值,并实时传输给运动控制器,运动控制器根据波浪补偿值的反解算法计算出横摇、纵摇、升沉的补偿值,根据补偿值控制各油缸动作,实现上层载体的三自由度补偿。
