摘　　要：介绍采用超声导波技术对近海管道进行检测。该技术可检测,导柱底部或水下管道关键区域。利用专门研制的机械系统可检测海平面下深达500 m的管道。讨论了导波技术检测水下管道及导柱底部的优势及局限性,给出了检测结果。The guided waves technology has been successfully used to screen offshore pipelines.Riser splash zone could be successfully screened from top-side position using the Wavemaker technology.Underwater pipelines could be screened using the sub-sea technology developed by Guided Ultrasonics Limited,which allowed the screening of tens of meters of underwater pipelines from a single location.

关 键 词：超声导波检测技术 海上管道 长距离检测
