刚性跨接管在海洋油气开采过程中必不可少，其安装受到各种因素影响，包括水下井口位置测量误差、由管道线性膨胀引起的位置误差、跨接管制造过程中自身存在的误差等，这些误差均为随机误差，在安装作业过程中这些误差将最终影响回接系统整体安装位置。本文采用数学中随机误差的统计合成方法对回接系统进行建模，最终给出合理的安装位置预测，为实际安装作业前的作业部署提供了可靠依据。

As an important part of the underwater production system,the installation of jumpers influenced by various of factors, including the error of subsea wellhead position measurement,the position error caused by the pipeline linear expansion,the existence errors in manufacturing process,these errors are random error,which will eventually affect the installation position of whole system during the installation process .This paper adopts the statistical error synthesis method in mathematics to modeling the tieback system,finally gives a reasonable prediction of the installation position,and provided reliable basis before the actual installation operation.
