拖航状态下自升式钻井平台桩腿结构强度分析

摘要

The theory of leg structure analysis for self-elevating drilling units under transit condition is illustrated and as an example, a jack-up with truss legs is analyzed by FEA method, which can explain the process and method for leg strength analysis of jack-up units. This paper may be helpful to the rig owners, operators and designers.%以某一桁架式桩腿的自升式钻井平台为例,阐述了拖航工况下桩腿强度分析的一般原理,并通过有限元分析和求解,说明此类移动平台桩腿结构强度分析的过程及方法.本文提供的方法和思路,对自升式平台使用者及平台设计人员具有一定的指导意义.
