Abstract:The development history of underwater detection technology related to marine engineering and its application in the practical engineering are systematically studied. By meticulously categorizing of the traditional underwater detection methods, and further analyzing and revealing its significant limitations, the basic principles of acoustic signal detection are set forth in detail, and the related equipment is comprehensively introduced. Combined with the detail detection items related to the marine engineering, the advantages and limitations of these new detection technologies in practical applications are deeply discussed. The analysis results show that compared with the traditional methods, the new underwater detection technologies have the distinct advantages, that is, the multibeam bathymetric system can provide the high-precision three-dimensional topographic data, the dual-frequency recognition sonar performs well in local detail detection, and the shallow stratum profiler can penetrate sediments to measure thickness or cross-section. The collaborative use of these technologies can effectively enhance the efficiency and accuracy of underwater detection related to marine engineering, significantly reduce the risks associated with manual underwater exploration, which provides the powerful technical support for quality control related to marine engineering. The application prospects of new underwater detection technologies related to marine engineering are further clarified, which provides the reliable references and basis for the research, promotion and application of the relevant technologies.
