参考某动力定位船舶的具体参数和该船的海浪响应幅值算子(RAO),结合该船工作时的具体过程,利用大型水动力分析软件OrcaFlex建立了船舶动力定位时的动力学分析简化模型.通过调节不同海况下的浪向,实现了对动力定位船舶在不同浪向下的动力学分析,对海浪作用下船舶的纵荡、横荡和转艏运动进行了数值仿真,得到了不同浪向对船舶动力定位精度的影响,确定了船舶动力定位时的最佳浪向,结合计算结果,给出了船舶动力定位的优化设计方案.

Based on the parameters of a certain vessel with dynamic positioning system and the response ampli-tude operator(RAO), combined with the specific process of the vessel at work, the model of the vessel with dynamic positioning system was established by using OrcaFlex. With the change of the direction of wave, the dynamic analy-sis of the system was made under different wave directions. At the same time, the digital simulation of ship's surge, sway and yaw motions were made. And the extent of influence on the dynamic positioning system under different wave directions and the optimum wave direction for the operation of dynamic positioning were gotten. According to the calculated result, the optimization design of the operation of dynamic positioning for the vessel was given.
