【摘要】 针对浮式生产储油船(FPSO)单点系泊姿态传感器的初始安装误差无法消除,其误差会严重影响系泊力计算精度的问题,提出了一种基于系泊结构运动特性和实测数据的动态校准方法。该方法基于安装在FPSO船体上的高精度GPS实测信息,和软刚臂系泊系统的运动关系方程,采用多样本组合优化法来校准姿态传感器安装误差。在"海洋石油102"FPSO的原型测量数据集上进行验证,结果表明,该方法可以有效地补偿软刚臂系泊姿态传感器的安装误差,为今后海洋平台传感器安装误差的研究提供了新的思路和方法。更多还原

【Abstract】 Aiming at the problems that the initial installation errors of single point mooring attitude sensors in FPSO(floating production storage and offloading) can not be eliminated and the errors seriously affect the calculation accuracy of the mooring force,this paper presents a dynamic calibration method based on mooring structure motion characteristics and real measurement data.The method is based on the real information from a high precision GPS installed on the FPSO and the moving relationship equation of the soft yoke mooring system,and adopts the multiple sample combination optimization method to calibrate the installation errors of the attitude sensors.The prototype measurement data set of "HYSY102" FPSO was used to evaluate this method.Experimental results show that the proposed dynamic calibration method can effectively compensate the installation errors of the soft yoke mooring attitude sensors.The method provides a new idea and method for the researches on the installation errors of offshore sensors in the future.更多还原
