以一艘搭载六自由度补偿平台的风电运维双体船为研究对象，基于三维势流理论和波浪绕射理论，开展船舶在风、浪、流耦合作用下的运动响应研究，分析船舶重心处的频域运动响应、附加质量以及辐射阻尼和时域运动响应历程，获得在不同浪向角与波浪周期中的船舶运动响应结果，并将船舶重心处的运动响应转换为六自由度补偿平台基座安装点位置处的运动响应，得到该安装点处的运动响应历程以及在不同浪向下的最大垂荡幅值，为该平台控制系统以及液压缸运动位移的运动学分析提供数据输入，为运维时机的选择以及平台液压机构的选型提供参考依据。
A wind power operation and maintenance catamaran with 6-DOF compensation platform is taken as the research object. Based on the theories of three-dimensional potential and wave diffraction, the article analyzed the ship's motion response under the coupling effect of wind, wave and current. The frequency domain motion response at the center of gravity of the ship, additional mass, radiation damping, and time domain motion response history were also analyzed, in order to obtain ship motion response results in different wave angles and wave cycles. The article also converted the motion response at the center of gravity of the ship to the motion response at the installation point of the 6-DOF compensation platform, and achieved the motion response history at the installation point and the maximum amplitude of the heave response in different wave directions. This paper is to provide the data input for the platform control system and the kinematic analysis of the hydraulic cylinder movement displacement, and reference for determining the suitable time for operation and maintenance and the selection of platform hydraulic pressure institutions.
