| Abstract: | In order to interpret the pipeline position and quantify the pipeline settling depth,multi-beam echo sounding techniques are used in the pipeline inspection.Multi-beam system components,installation calibration,survey method and data processing in the pipeline inspection are introduced.The data processing of the multi-beam echo soundings and some special data analyses in order to interpret the pipeline position and quantify the pipeline settling depth based on DTM are stressed.Some factors,such as frequency,beam angle and water depth,influencing the resolution of the multi-beam echo sounder are also discussed. The analyses suggest that the multi-beam echo sounder has higher resolution and is more effective and visual in comparison with the single beam echo sounder.The use of multi-beam sounding techniques should become more prevalent in view of their numerous advantages over single beam systems in submarine pipeline inspection. |
