摘　　要：随着海洋工程建设及海上事故和海难的增多,日益增加的海底障碍物给海上安全生产和航运带来了前所未有的挑战和安全隐患,需要进行海上搜寻和水下探摸与处理。旁侧声呐和动力定位船的配合使用是处理这类问题的最佳选择,但租用动力定位船费用昂贵,成本很高。而根据工作区的实际情况利用渔船改装的动态定位船操作简单,且费用低廉,被海洋工作者广泛采用。本文介绍了旁侧声呐在海底障碍物探测中的应用和渔船改装的GPS动态定位船进行水上定位的工作原理和施工方法。装备GPS导航软件的渔船可以指示船只的实时位置。通过改变锚绳长度来改变船只位置的动态定位技术适用于水下搜寻和探摸处理工作。With the increase of ocean engineering projects and ocean＇s accidents and wrecked ships, unprecedented challenges and hidden perils caused by increasing submarine obstacles are faced by marine development and navigation. These submarine obstacles have to be searched and dealt with. Co-application of Side-Scan Sonar and kinetic positioning vessels is the best selected to resolve the problem, but the cost is too high. Refitted fishing-boats are a possible substitute, and they are adopted widely now in offshore survey. The application of Side-Scan Sonar in submarine survey and the dynamic positioning principle of working with refitted fishingboats are introduced in this paper. The method is proved to be feasible in practice.
