无人艇海管检测系统的研制及应用

Development and application of subsea pipeline detection system based on the Unmanned Surface Vessel

为保证海底管道的安全运行,定期巡检必不可少,而传统检测方法存在诸多问题,限制了海管检测的频率和效率。为此,提出一种无人艇(Unmanned Surface Vessel,USV)海管检测系统,该系统通过在USV上搭载海管检测系统,可实现出海作业由岸上人员远程操控,并可自主航行开展巡线。USV海管检测系统由USV子系统、海管检测任务系统、数据处理及展示系统构成,该系统主要基于导航定位、USV测线航迹预置、三维成像声呐、浅地层剖面仪等关键技术完成海管检测。目前,USV海管检测系统已投入到胜利油田埕岛油田的管道检测工作中,并开展了对大部分管道的扫测,可获得裸露、悬空管道的长度和高度,进一步提高了海管检测的效率,为海底管道的检测工作提供了一种更加安全、直观、快捷的新方法。

In order to ensure the safe operation of subsea pipelines, it is necessary to perform inspection periodically. However, there are many constraints in the traditional detection methods, which limit the frequency and efficiency of subsea pipeline inspection. For this reason, a subsea pipeline detection system based on the Unmanned Surface Vessel(USV) was proposed. The system, with a subsea pipeline detection system installed on the USV, is capable of realizing offshore operation under the remote control of person on shore and inspecting the pipelines with autonomous navigation. The USV-based subsea pipeline detection system is composed of a USV subsystem, a subsea pipeline detection system and a data processing and presentation system. The system realizes subsea pipeline detection based on navigation and positioning, presetting tracks of USV survey line, 3D imaging sonar and sub-bottom profiler. Currently, the USV-based subsea pipeline detection system has been used for the pipeline detection of Chengdao Oilfield in Shengli Oilfield, and scanning inspection was performed for most of the pipelines, obtaining the length and height of the bare pipelines and the suspended pipelines, which can further improve the efficiency of subsea pipeline inspection and provide a new method that is safer, more intuitive and faster for inspection of subsea pipelines.
