摘要
针对某铺管船开展海上动力定位实测研究,测量海洋环境、船舶六自由度运动和推进器等参数。采用比例积分微分控制算法对该铺管船动力定位响应进行数值模拟。将海上现场监测结果与数值模拟结果进行对比,两者吻合较好。研究有助于掌握该铺管船的动力定位特性,为海上动力定位铺管作业提供技术支持和参考。
Field measurements are carried out for the dynamic positioning of a pipe-laying vessel.The sea environments,6 degree motions and the propellers of the vessel are measured.The dynamic positioning responses are simulated using the proportional-integral-derivative control algorithm.The field measurement results are compared with those predicted by numerical simulation.Fair well agreement is reached.The research is helpful to learn the dynamic positioning characteristics of the pipe-laying vessel,and can be used for technical guide on practical offshore operations.
