自升式平台齿轮箱及导向结构强度研究

Research of Structural Strength of Jackcase and Guide for Jack up

升降和锁紧系统是自升式平台的重要组成部分,与其所连接的齿轮箱和导向结构强度对自升式平台也具有重要意义。以某自升式钻井平台为例,应用有限元方法,对齿轮箱和导向结构在不同组合工况下的屈服强度进行研究,结果表明,该自升式钻井平台结构强度满足要求。

The lifting and locking system is an important part of the jack-up platform, and the strength of the gearbox and guiding structure connected to it is also important for the jack-up platform. Taking a jack-up drilling platform as an example, the finite element method is applied to study the yield strength of the gearbox and the guiding and surrounding structures under different combined conditions. The results show that the structural strength of the jack-up drilling platform meets the requirements.
