| 摘 要： | FPSO船体姿态运动(纵摇和横摇)会对FPSO与穿梭油轮的靠泊、FPSO上直升机的起降、海上的补给等作业可能造成严重的影响。如能实现在一定时间内对FPSO船体姿态运动进行预报,则可大大提高这些作业的安全性和高效性。用AR(p)模型拟合FPSO纵摇运动,然后运用AR(p)模型的线性最小方差预报法进行预报,预报实例中用到的数据来自模型试验。结果表明,用时间序列法对FPSO纵摇运动进行极短期预报具有一定的精度和较小的计算量。

| Abstract: | Operations,such as berthing a shuttle tanker beside FPSO,taking off or landing a helicopter on FPSO,and replenishment at sea,may be seriously affected by pitch and roll of FPSO.The ability of predicting the motions of FPSO in some time is very helpful for safety and efficiency of those operations.In this paper,AR(p) model is be used to match the pitch motion of FPSO.Then the motion can be predicted using AR(p) Linear Minimum Variance method.The data in the process of practical prediction come from the model test.The results show that extreme short prediction of FPSO pitch motion using time series method is accurate and the calculation is simple. |
