Abstract
In the complex marine ecological environment,with the increase of the service life of submarine pipelines,the phenomenon of exposed and suspended diseases of submarine pipelines is obvious,which seriously threatens the safety of offshore oil production.In order to accurately evaluate the development degree of the suspension of the sea pipe and guide the construction of the treatment project.The remotely operated vehicle(ROV)was equipped with a multi-beam echo sounder to carry out short-distance detection.The exact position,height and length of the suspended section of the submarine pipeline were determined,the treatment of suspended rocks was guided,and the treatment effect was evaluated.The results showed that the ROV equipped with a multi-beam depth sounder could get close to the pipeline at a close distance,complete refined detection,avoid the influence of sea waves and tidal surges on multi-beam detection,and more accurately evaluate the degree of disease and guide the construction of treatment.关键词
