多波束和侧扫声呐系统在海洋管道建设中的应用

Application of Multi-beam and Side-scan Sonar Systems in Offshore Pipeline Construction

多波束能够获取海底全覆盖的高精度水深数据,但地物的判读性较弱;侧扫声呐能够获得海底地貌声像图,能够直观判读海底表层特征,但图形中的目标定位及深度的判断能力较差。综合应用多波束和侧扫声呐系统,能够提高地物特征识别的准确性和可靠性。本文以某海洋管道项目为依托,探讨两系统在海洋管道建设中的综合应用。

Multi-beams can be used to obtain high-precision data on water depth,which fully cover seafloor.However,it is hard to interpret the ground features.Side-scan sonar is used to produce the sound and image graphs for submarine terrain,and intuitively grasp the seafloor surface features,but it is difficult to position the target and determine the target depth in the graphics.The combination of the above two systems can improve the accuracy and reliability of feature recognition.A marine pipeline project is analyzed to discuss the comprehensive application of the two systems in offshore pipeline construction.
