Application of Real-aperture Imaging Sonar in the Detection of Subsea Oil and Gas Pipeline

It is one of the most important acoustic measuring means to detect subsea oil and gas pipeline by using imaging sonar.Side-scan sonar and ring-scan sonars are two typical real-aperture imaging sonars,and this paper introduces the imaging principle of these two types of sonar.Then,a comprehensive comparison is made from the aspects of carrying platform,scanning characteristics,parameter displaying and acoustic image characteristics.Finally,the application effect of two types of sonar on the detection of subsea oil and gas pipeline is given,and their advantages and disadvantages are compared and analyzed.The conclusions have practical reference significance for understanding and mastering the performance of side-scan and ring-scan sonar equipment,and for detecting and condition accessing the subsea oil and gas pipeline.
