海底管道检测遥控水下机器人发展现状与关键技术OA

Defects such as corrosion and cracks were easily generated in subsea pipelines under the long-term influences of the marine environment.Limitations such as low safety,insufficient efficiency,and high cost existed in traditional detection methods,therefore,ROVs equipped with professional detection equipment were gradually adopted as the mainstream detection scheme.The classification,performance,and system composition of ROVs were first comprehensively analyzed.Then,based on the actual require-ments of subsea pipeline inspection and combined with the research status of ROV-based inspection technol-ogy,the existing technical characteristics of subsea pipeline inspection ROVs were analyzed.Subse-quently,the key technologies of ROV-based subsea pipeline inspection were further discussed.The techni-cal principles of optical inspection technology,acoustic inspection technology,electromagnetic inspection technology,and radiographic inspection technology were elaborated,and the characteristics and applicable scenarios of each inspection technology were summarized.Finally,the future development of subsea pipe-line inspection ROVs was prospected.
