摘　　要：针对仅依赖系泊船长个人经验指挥外输作业易引起FPSO和穿梭油船发生碰撞或系泊大缆断裂的问题,基于全球定位系统实时测量船舶的高精度差分定位数据,采用最小二乘法原理构建数学模型,运用线性回归方法对船舶定位数据进行数值拟合分析,预测出60 s内FPSO和穿梭油船的航向和位置,从而为系泊船长及时发出正确指令提供参考依据,现场测试数据误差分析结果表明,采用该方法可实现较高的船舶航向和位置的预测精度,满足工程实际需求。In order to solve the problem that FPSO and shuttle tanker collision or mooring cable fracture are easily caused by the personal experience of a mooring master,based on the real-time measurement of a ship's high-precision differential positioning data by global positioning system,the mathematical model was established by using the principle of least square method,and the ship positioning data were fitted and analyzed by linear regression method.The course and position of FPSO and a shuttle tanker within 60 seconds were predicted,so as to provide the reference for the mooring master to issue correct instructions in a timely manner.Through the error analysis of the field application test data,the results showed that the method realizes the prediction accuracy of the course and position of the ship,and can meet the practical needs of the project.
