侧扫声纳在海底管道悬空调查中的应用

海底管道在铺设及运营过程中,受各种因素的影响,会形成部分悬空状态。为保证油管的安全运营,研究了一种基于声学的快速检测方法:主要利用侧扫声纳获取油管附近声学影像,通过数据判读的方法分析并获取管线状态。然后使用该方法,在册镇海底管线调查中进行了应用测试。声学检测结论与水下探摸结果进行比较,测试结果表明该方法可高效、快速、准确并低成本地检测管线状态,可为海底管道运营与治理提供有力的技术支持。

Application of Side-scan Sonar in Suspended Submarine Pipeline Investigation

Lots of situation may cause pipelines spanned when laying and running submarine pipelines.In order to keep the pipelines safe during operating,this paper introduced a fast detective method of using side-scan sonar to fetch acoustic images near the pipelines and get the status by data interpretation based on acoustics.Later we used this method to do a application test in the Cezi-Zhenhai underwater pipeline investigation.Comparing the different results got by acoutic methods and underwater manpower checks,it demostratored the method offered by us can invest pipelines in a cheap fast effective and accurate way,offering powerful technical support for running and governing pipelines.
