摘要： 系统阐述了张力腿平台(TLP)在位总体性能分析的设计工况分类原则及数值计算流程,简要介绍了频域及时域分析方法。结合南海TLP前端设计,重点介绍了TLP数值建模遵循的原则以及平台质量特性、张力筋腱和立管的刚度及外部阻尼的计算方法。最后通过实例计算给出南海环境条件下TLP在位总体性能计算结果。所用流程及方法可供南海深水浮式平台设计参考。

Abstract: The load case category and numerical calculation procedure of tension leg platform (TLP) in-place global performance analysis are systematically stated. Meanwhile, the frequency domain method and time domain method are simply introduced. According to a TLP front end engineering design project at South China Sea, modeling principles related to panel meshing, calculation methods of TLP mass properties, stiffness introduced by tendons and risers, and TLP external damping are introduced. At last, the main results of in-place global performance analysis are listed. The procedure and methods used could be a reference for other analogous projects at South China Sea.
