摘要
以某最大作业水深3000m完修井船为研究对象,采用基于三维水动力理论的谱分析设计波法,选取设计波参数,进行操作T况和生存T况下波浪T况的波浪载荷预报。施加设计波浪载荷,通过准静态的有限元分析,得到总体结构的应力水平和分布。根据规范衡准对结构强度进行校核评估。
Global strength analysis of a 3 000 Ill work-over and well completion unil was assessed. By means of 3-D diffraction theory and spectrum analysis method, the design wave parameters were selected. The wave loads in eonditions of survival and drilling loading were predicted. These wave loads were applied to the global structural model to calculate directly the stress distri- bulion of the structure. The structural strength was assessed according to ABS MODU.
