摘要时代的进步，社会的发展离不开资源的支持，当前陆地资源已经严重不足，已经不 足以支持社会的持续进步与发展。于是人们将注意力集中到开发和利用海洋资源。地球 上百分之七十面积都是海洋，有非常丰富的资源。如何去有效的利用海洋资源，这个时 候就需要我们借助于海洋平台去开发海洋资源。而半潜式平台在海洋平台中扮演重要角 色。77860

在第二章中对半潜式平台进行了介绍，对系泊系统和锚系统做出了详细的分析。 在第三章中介绍了波浪力计算的知识和动态响应分析理论中关于系泊系统的知识，对半潜式平台受到载荷的作用和系泊系统与平台的耦合动态响应有了进一步的深入了 解，将系泊系统和平台的耦合响应进行一个综合分析进而进行进一步的计算，最后得出 结论。

在第四章中研究半潜式平台与其系泊系统的耦合运动响应，运用 SESAM 软件 GeniE 模块对“海洋石油 981”半潜式平台进行建模，Hydro 模块进行水动力性能分析和 DeepC 模块进行系泊系统建模以及数值模拟计算系泊缆静态和动态张力和六自由度下平台的 耦合运动响应，分析平台与系泊系统的耦合运动响应结果。

第五章介绍了系泊系统与半潜平台动态响应分析，通过 4 种不同的工况分析了风和 流作用，波浪的作用以及系泊系统完整性对系泊缆静态和动态张力以及平台六自由度耦 合运动响应的影响，得出了一系列结论。

Abstract With the progress of the times, the development of society cannot be separated from the support of resources, the current land resources have been seriously inadequate。 It is not enough to support continuous improvement and development of the society 。The seventy percent area of the earth is the ocean, there are very rich resources。 How to effectively use the marine resources, which requires us to use the ocean platform。 Semisubmersible platform plays an important role in the offshore platform。

In the second chapter, the semisubmersible platform is introduced, and the mooring system and the anchor system are analyzed in detail。

In the third chapter, the paper introduced the calculation of wave forces acting on the dynamic response analysis theory of knowledge and the knowledge about the mooring system, learn more about the semi-submersible platform by the effect of load and the coupling dynamic response of the mooring system and platform。 Finally, we draw a conclusion through the research。

In the fourth chapter， Software SESAM with its three modules is used to solve the

problem, firstly the GeniE module is made great use of to manufacture the modeling of semi-submersible which is called HYSY 981, then with the module of HydroD。 it was made possible to calculate and analyze the Hydro-dynamic performance of this semi-submersible, eventually the DeepC module is put in use to architect the model of the mooring system so the mooring line’s static and dynamic tension accompanied with the coupled-dynamic response in the six degrees of freedom could be calculated and  simulated, then  results which are calculated would be analyzed。

The fifth chapter introduced mooring system with a semisubmersible platform dynamic response analysis, through 4 distinctive working conditions, influence of the wind, current, wave and the integrity of the mooring on the static and dynamic tension of the mooring lines and coupled-dynamic response in the six degrees of freedom are analyzed, some conclusion would be drawn。

Keywords: Coupled-dynamic response analysis;SESAM; Mooring system
