摘要

摘要: 由于海流潮冲刷等影响,软土海床上的海底管道存在大量裸露甚至悬空,易导致海底管道存在安全稳定风险。基于传统的海底管道检测方法不能全面、精细地反映海底管道的状态信息,无法准确判断海底管道的安全状态。因此,提出一种基于多源数据融合的在役海底管道3D建模方法。该方法通过声波探测技术获取海底管道数据信息,融合含有海底管道状态的多源数据信息,提取识别海底管道及其空间坐标信息,以胜利油田海底输油管道为研究对象,建立海底管道3D模型,实现海底管道3D可视化精细表达,确定海底管道空间位置状态;并对海床上处于不同位置状态下非掩埋管道的安全裸露长度的进行分析计算,结合3D精细模型分析得到在役海底管道的实时安全稳定状态。

Abstract: Due to the scouring of bottom turbulent currents, the submarine pipelines on the soft seabed become exposed or unsupported so that they will be instable. The conventional methods for inspecting the submarine pipelines are inadequate and unprecise to reveal the actual status of submarine pipelines. It makes it difficult to analyze the safety of the pipelines. Therefore, a new method for inspecting the status of submarine pipelines is proposed to obtain their precise status information, where the surveying data collected by side-scan sonar, sub-bottom profiler and multi-beam bathymetric systems are integrated together to make precise visual 3D models and to determine the spatial position information of the submarine pipelines. Based on the precise visual 3D models and the spatial position information, the stability analysis is then conducted on the 3D models to evaluate the reliability of the pipelines at different parts.
