摘要
总结自升式平台的刺穿事故,编制计算自升式平台船体浮力的程序,采用非线性有限元分析的方法,研究船体浮力对提高自升式平台极限刺穿深度的效应,为最终开发出降低刺穿风险的压桩决策系统奠定基础。
In this paper, the reasons for jackup punch through accidents have been summarized. A computer program for the calcula- tion of hull buoyancy has been developed. By considering the effect of hull buoyancy, a nonlinear finite element approach is proposed to study the buoyancy effect in increasing the jackup punch through capacity. The current study lays down the foundation for the development of a jackup preloading management system with the objective of minimizing the risk of punch through during jackup deployment.
