深水导管架平台隔水导管导向孔布置分析

Arrangement Analysis on the Guide Holes of Conductor for Deep-water Jacket Platform

为使深水导管架上隔水导管导向孔布置设计更为合理,运用挠曲线方程和有限元软件ANSYS计算分析导向孔的布置数量和位置,得到隔水导管最下层导向孔优化的布置位置,并给出设计导向孔位置的完整步骤,以330 m水深的深水导管架平台为例,对导向孔的位置布置重新设计,结果表明,在同样数量的导向孔下,新方案可以达到更好的稳定性,并能提高每一层导向孔的标高,有利于导向孔的深水工程施工。

In order to rationalize the layout design of the guide hole of the conductor on the deep-water jacket,the number and location of the guide hole were studied by using the deflection curve equation and Ansys software.The optimal location of the guide hole at the bottom layer of the conductor was obtained,and the complete steps of the location design of the guide hole were given.Taking the deep-water jacket platform of 330 m water depth as an example,the location of the guide holes was redesigned.The results showed that the new scheme can achieve better stability under the same number of guide holes,and improve the elevation of each layer of guide holes,which is conducive to the deep-water engineering construction of the guide holes.
