可调立柱式新型半潜钻井平台强度分析

The strength analysis on the new semi-submersible drilling platform with adjustable column

以可调立柱式新型半潜钻井平台为分析对象,首先根据设计波法确定平台风暴自存环境波浪参数,并将这些参数换算成所需载荷;然后用ABAQUS建立平台三维有限元模型,并对模型施加上述载荷;最后经过处理获得平台应力分析云图和位移云图,为可调立柱式新型半潜钻井平台结构设计、平台优化、强度分析提供强有力的支持。

It demonstrates the global strength analysis on a new semi- submersible drilling platform with adjustable column. It defines the parameters of the platform in survival condition based on design wave method,and converts these parameters to the load required at the same time. Then it establishes three- dimensional FEM model of the platform in ABAQUS,obtains the stress distribution and the displacement contours. The result provides the strong support to design and platform optimization.
