随着世界经济的高速发展，能源和资源短缺问题日益突出。由于陆地和近海油气资源的逐渐减少,为满足飞速增长的能源需求, 世界发达国家将油气资源的开发重点转向了深海,深水半潜平台应运而生。第六代深水半潜平台是一个典型代表，其作业水深达3000米，钻井深度10000米，是开发海洋油气资源的重要技术性装备，也是一个国家装备制造综合技术的重要体现，研究、设计、制造半潜平台具有非常重要的意义。
管线是深水半潜平台中非常重要的部分，由于平台漂浮于海上，环境条件恶劣，受力复杂，再加上系统复杂众多，工作压力高等因素，对平台管线进行应力分析成为平台设计和建造的关键点。
本文利用CAESARII应力分析软件，着重从管路应力方面对深水半潜平台关键管系高压泥浆系统、高压空气系统、钻井液压系统和玻璃钢压载水系统做了分析研究，主要研究内容如下：
1、论述总结了深水半潜平台关键管系应力分析的意义及目的，在管道应力分析的理论部分，详细说明了规范ASME B31.3对应力分析的评判准则，给出了一次应力和二次应力校核条件。整理了管系应力分析工作的具体任务和过程，论述了分析过程的各个环节。
2、运用CAESAR II管道分析软件建立半潜平台关键系统应力分析模型，并进行计算。对现行设计下管路系统的一次应力和二次应力水平进行校核，验证了现行设计的可行性。
3、针对压载水系统的重要性，对压载水系统单独进行了水锤载荷动态分析和压载水离心泵进出口载荷评估，提高系统安全性。
4、最后作为一个扩展，对高压泥浆系统进行了静态疲劳分析，加载系统预期的循环次数，设置了三个疲劳工况。通过对三个疲劳工况单独作用和累计作用的分析，得出系统的应力在合理的范围内。

Abstract
With the rapid development of world economy, the sources of energy and resource issues have become increasingly prominent. Because the land and offshore oil and gas resources are gradually reduced, in order to meet the growing demand for energy, the world’s advanced states focus on the deep sea oil gas resource development, so the deepwater semi-submersible platform emerge as the times required. The sixth generation of deepwater semi submersible platform is a typical representative, its operating water depth is 3000 meters, drilling depth is 10000 meters, which is an important technical equipment for the development of offshore oil and gas resources, also is an important reflection of a national equipment manufacturing integrated technology level, So the research, design and manufacture of semi submersible platform have very important significance.
The pipeline is a very important part of the deepwater semi-submersible platform, due to the platform floating on the sea, bad environmental conditions, complex stress, coupled with the system is complex and numerous, and higher working pressure, the pipeline stress analysis of the platform become a key point in the platform’s design and construction.
This article use CAESAR II software to analyze the pipelines stress of semi submersible platform, the pipelines mainly include high pressure mud system, high pressure air system, drilling hydraulic system and FRP ballast water system, the main research contents are as follows:
1、This paper summarize the meaning and purpose of the semi submersible platform key pipelines’ stress analysis. In the pipe stress analysis theory, a detailed description of standard B31.3 stress analysis criterion, given primary stress and secondary stress check condition. Combing the pipe stress analysis tasks and process, and each link of the analysis process were discussed in detail.
2、This paper use CAESAR II to establish the models of the semi-submersible platform key system, and calculate the result to check the primary stress and secondary stress levels, verified the feasibility of the design current.
3、Aiming at the importance of ballast water system, this article carry out ballast water system water hammer load dynamic and ballast water centrifugal pump import and export load assessment, improved system security.
4、Finally, as an extension to high pressure mud system, this paper implement static fatigue analysis of high pressure system, loading system expected cycle numbers, setting three fatigue conditions. Through the three fatigue conditions alone and cumulative effects analysis, obtained the system stress in a reasonable range.
In conclusion, this paper preliminarily explored some feasible semi submersible platform piping stress analysis method and obtained some useful conclusions, which laid a good foundation for engineering application and further study in future.
