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。
Due to the impact of the sea current flushing and other impacts, there is a large amount of exposed or even vacant submarine pipelines on the soft sea floor, which easily leads to the risk of safety and stability of the submarine pipelines. The traditional submarine pipeline detection method can not comprehensively and finely reflect the status information of submarine pipelines and can not accurately determine the safety status of submarine pipelines. Therefore, a 3D modeling method for in-service subsea pipeline based on multi-source data fusion is proposed. The method obtains the submarine pipeline data information by acoustic wave detection technology, merges the multi-source data information containing the submarine pipeline status, extracts and identifies the submarine pipeline and its space coordinate information, and takes the seabed oil pipeline of Shengli Oilfield as the research object and establishes the submarine pipeline 3D model to realize Submarine pipeline 3D visualization of fine expression, to determine the location of submarine pipe space position; and on the sea floor at different positions under the state of non-buried pipe safety bare length analysis and calculation, combined with 3D fine model analysis of submarine pipeline in real-time security and stability .
