摘　　要：在动力定位船吊装海洋平台上部组块作业的过程中,准确预报起重船和上部组块的耦合运动响应,增强起重船的动力定位能力,对于保障组块吊装作业的安全性与稳定性十分重要。用耦合刚度法建立耦合运动模型,并基于模糊PID算法与遗传算法设计动力定位系统控制算法;开发起重船和上部组块耦合运动响应的数值仿真程序,实现耦合运动时域响应求解;开展海洋石油201动力定位起重船组块吊装模型试验,分析比对仿真与试验结果,进而评估组块吊装作业的安全性,为动力定位起重船吊装海洋平台上部组块作业提供指导。During the operation of lifting an offshore platform topside by a dynamic positioning vessel,it is important to predict the coupled motion response of the crane vessel and the topside,and enhance the dynamic positioning capability of the crane vessel,to ensure the safety and stability of the topside lifting operation.The coupled motion model of the crane vessel and topside is established through the coupled stiffness method,and the control algorithm of the dynamic positioning system is developed based on the fuzzy PID(proportional-integralderivative)algorithm and the genetic algorithm.The numerical simulation program has been developed to solve the dynamic response of coupled motion in the time domain.The model tests of HYSY201 have been conducted,and the analyses and comparisons have been carried out between simulation and test results.The safety of topside lifting operations is evaluated,and the guidance of dynamic positioning topside lifting operations is provided.
