无人船在油气管道水域穿越工程中的应用

The application of unmanned boats in water-crossing engineering for oil and gas pipeline

近年来,无人测量船(以下简称无人船)技术发展迅速,在工程建设中的应用也越来越广泛。为了研究无人船在油气管道水域穿越工程中的测量工作内容和技术特点,介绍了无人船的工作原理、技术特点和作业流程,并分析了传统水域测量的不足。通过某LNG管道大型河流穿越工程案例,介绍了河流穿越概况、无人船设备情况及数据采集方案,详细说明了无人船数据处理中数据检查和改正两个关键点,分析了精度情况、作业效率和经济效益。结果表明无人船水域测量安全、准确、高效。研究内容对类似项目的无人船应用具有重要参考价值。

In recent years,the technology behind unmanned survey boats has advanced considerably,with an increasing number of applications in engineering construction.This study delves into the tasks and technical features of unmanned boats in oil and gas pipeline water-crossing engineering.By contrasting this method with traditional underwater topographic surveys,the shortcomings of the latter become evident.The working principles,technical features,and workflows of unmanned boats are analysed and highlighted.An application involving an LNG pipeline crossing a river serves as a case study,detailing the overall river crossing scenario overview,equipment used,and data collection strategy.Special attention is paid to two crucial stages in data processing:data inspection and correction.An analysis of both the data accuracy and operational efficiency was conducted.The findings underscore the superiority in the aspects of safety,accuracy,and efficiency of using unmanned boats for water surveys.The insights presented in this paper are invaluable for future applications of unmanned boats in similar projects.
