海底管道检测数据平面偏差与管道状态分析研究

Comparative analysis on inspection data horizontal movement and state of submarine pipeline

当前海底管道研究内容主要集中在检测方法、管道三维模拟和系统建设方面,对检测数据分析与方法讨论较少。本文介绍了海底管道检测数据来源及其内容,讨论了海底管道节点平面偏差分析原理,对不同测次管道平面偏差比较的采样点选取展开研究,并分析了海底管道状态成果数据编制与历次管道状态比较内容,对管道状态区间跨度计算存在的情况进行详细讨论,同时给出相应的解决方法。本研究成果已应用于杭州湾海底管道检测数据分析,为其他海底管道检测数据分析提供借鉴与参考。

Submarine pipeline research mainly focuses on the detection method, pipelines 3D simula- tion and system construction, while less discusses the data analysis. It introduced the sources and contents of submarine pipeline inspection data, then discussed the concept of submarine pipelines horizontal move- ment, and researched into selecting the compared sampling points of horizontal movement at different times. Finally it analyzed the data preparation of submarine pipeline status and the compared contents of different state data, discussed the interval span calculation condition of pipeline state, and presented the related solution. The result has been used and verified in Hangzhou Bay submarine pipeline inspection data analysis with a good referential value.
