【摘要】 自升式钻井平台在海上作业中曾出现过一些振动问题。为考察自升式钻井平台的振动特性,以胜利5号自升式钻井平台为例,运用大型有限元程序MSC/NASTRAN,对平台结构自身的振动特性进行了有限元分析,得出相应的结论,这对这类平台的振动分析和设备更新具有参考价值。更多还原

【Abstract】 Some vibration problems have been occurred in offshore operations of jack-up rigs. In order to review the vibration features of jack-up rigs, Shengli no. 5 platform was used as an example, by using large scale finite element analysis software MSC/ NASSTRAN to analyze its vibration performance and draw related conclusions which may be used as a good reference in the analysis and upgrading equipment of the jack-up rig.更多还原
