非对称半潜式重型起吊平台总体屈曲强度评估

Global Buckling Strength Assessment of Heavy Lifting Semi-Submersible Platform of Unsymmetrical Structure

介绍了非对称式半潜起吊平台SSCVII平台的结构特点,按照ABS规范,采用直接计算法对总体结构的屈曲强度进行了评估。通过建立总体有限元模型,分析了在静水工况、风暴自存工况、正常工作工况、拖航工况、破损工况五种工况下总体结构的屈曲强度,为以后同类平台的总体屈曲强度分析提供借鉴。

This paper mainly describes the structure characteristic of SSCVII.In accordance with ABS MODU rules the global structure buckling assessment was carried out based on the direct calculation.A global finite element model is built and the global buckling strength analysis is performed under five conditions including still water,storm survival,operation,transit and redundancy conditions.And it could be concluded that the global buckling strength is sufficient.It may be referenced for the global structure buckling assessment of other platforms of similar type.
