摘要
以南海某柱稳式半潜平台为例,介绍了半潜式平台结构强度评估的分析方法和流程。用基于三维水动力理论的设计波方法选取出平台在生存工况下的设计波参数,然后利用SESAM软件计算出平台所受的波浪外载荷,并用有限元方法来进行结构强度分析,最后根据规范对平台主体结构的应力水平进行了强度校核。
This paper presents some design techniques and analysis procedures for a semi-submersible platform in the South China Sea. Initially, considering the stochastic analysis method, some design waves are chosen for survival condition. Then, using SESAM program, 3-dimensional hydrodynamic load analysis and finite element structural analysis are performed. Finally, the stress and its distribution trend were obtained for the evaluation of structure strength.
