摘要： 针对深海复杂恶劣的环境条件，根据三维势流理论和凝集质量法，建立了深海养殖辅助工作船及其系泊系统的数值模型，研究了风浪流的共同作用下深海工作船系泊运动响应。首先通过频域分析，得到工作船在单位规则波下的幅值响应算子RAO等水动力参数；再将船体频域结果导入到时域分析中，模拟得到在风浪流的联合作用下深海工作船系泊系统的运动响应。结果表明：工作船在工作海况中可保持良好的状态，极限海况下横摇和纵摇运动超出规定范围，易发生险情；与风浪流方向均为180°相比，当流向为90°时，工作船横荡运动幅值增大，纵荡运动幅值减小，艏摇角度增大，同时流向的改变也会引起系泊缆有效张力的变化；各系泊缆安全系数满足安全性要求。

Abstract: In view of the complex and harsh environment conditions in the deep sea, this paper establishes a numerical model of the vessel and its mooring system based on the three-dimensional potential flow theory and the agglutination mass method. Through frequency domain analysis, the amplitude response operator (RAO) and other hydrodynamic parameters of the aquaculture vessel under unit regular waves are obtained. Then, the frequency domain results of the hull are imported into the time domain analysis to simulate the motion response of the mooring system of the deep-sea aquaculture ship under the combined action of wind, wave and current. The results show that the aquaculture vessel can maintain a good condition in working sea conditions. In the extreme sea conditions, the rolling and pitching motions are beyond the specified range, which is prone to dangerous situations. Compared with the wind, wave and current are all at the direction of 180°, when the current direction is 90°, the amplitude of the sway motion increases, the amplitude of the surge motion decreases, and the yaw angle increases. At the same time, the change of flow direction will also cause the effective tension of the mooring line to change. The safety factor of each mooring line meets the safety requirements.
