摘　　要：导管架海上安装时,在海床基础上预先设置基盘导向桩,并在导管架上设置套筒,可以有效地辅助导管架精确定位,实现水下井口预钻井,缩短油气田开发周期。针对安装过程中导管架与水下导向桩对接时的相互作用,采用MOSES软件,通过时域模拟,分析对接过程中的运动和碰撞载荷,并将数值分析结果与相关规范计算结果进行了对比。分析结论对于今后的导管架水下对接项目具有一定的参考价值。For offshore installation of jackets,subsea template guide pre-installed on seabed and sleeves designed on the jacket are beneficial to the rapid and accurate positioning of the jacket.Subsea wellheads can be pre-drilled and the development period of oil and gas field can be shortened by adopting this installation method.To investigate the interaction between jacket and guide pile during docking,MOSES software is used for the analysis of motion and impact load in time domain.The analysis results are compared with the results according to the relevant standards.The conclusions of this research have a certain reference value for the projects using subsea docking installation method.
