摘要: 由于顶张紧立管(TTR)一般在平台的井口区域进行密集布置,因此其干涉分析是工程设计中的重要环节。以张力腿平台(TLP)上的TTR为依托进行了干涉敏感性分析,对比了不同顶部张力、立管间距、平台位移和平台运动情况下的立管干涉分析结果。分析表明顶部张力和平台位移对干涉有着主要影响,准静态干涉分析能够反映干涉现象,设计初期可不必进行动态计算,从而减少工程设计工作量。

Abstract: As the top tensioned risers (TTRs) are intensively arranged in the wellhead zone in the platform, the interference analysis between TTRs is one of the most important engineering design parts. Interference sensitivity analysis is carried out based on the TTRs in a tension leg platform (TLP), and the interference results with different top tensions, riser spaces, TLP offsets and TLP movements are compared. The analysis results show that the top tension and TLP offset have the major impact on the interference analysis, and the quasi-static interference analysis can reflect the interference phenomenon, the dynamic analysis is not necessary in the early design stage, which can reduce the engineering design works.
