第七代超深水钻井船环境烈度因子研究

Research on Environmental Intensity Factors of the Seventh Generation Ultra Deepwater Drilling Ship

介绍了钻井船环境烈度因子的计算方法及其在结构设计上的应用,以第七代超深水钻井船为例对环境烈度因子的应用方法与原理进行阐述。基于波浪载荷直接计算方法,分别计算第七代超深水钻井船在北大西洋与指定作业地点两种环境条件下的波浪载荷长短期响应,最后得到典型钻井船环境烈度因子,对算得的钻井船环境烈度因子结果进行分析,确定钻井船结构设计的控制工况。

It describes the calculation method and application for structure design of drilling ship environment severity factors,the theory and application method of environment severity factors on an Seventh Generation Drill Ship is represented taking the seventh generation ultra deepwater drilling ship for example.Based on the directly calculation method of wave loads,the long and short term wave loads of the seventh generation ultra deepwater drilling ship are calculated respectively for the North Pacific Ocean and working site specified,the environment severity factors are concluded at last,it analyzes the calculation results of the environment severity factors,makes sure the control working condition of the drill ship structure design.
