Problems solved by technology

[0008] At present, a set of two-dimensional forward-looking sonar is mostly used on ROV, which is installed in front of the ROV platform to detect the submarine pipeline in front of the ROV platform. The angular direction has the ability to resolve, so only two-dimensional information of the target can be obtained

Abstract

The invention discloses a submarine pipeline detection device based on an ROV platform. The submarine pipeline detection device comprises a deck unit and an underwater detection device. The underwater detection device integrates a set of multi-beam sonar, a set of single-beam sonar, an optical imaging system, an illumination system, a CTD, an electronic compass, an acoustic beacon and an electrical system on the ROV platform. The multi-beam sonar is arranged in front of the ROV platform. The single-beam sonar is arranged below the ROV platform. By arranging two sets of two-dimensional foresight sonar, the resolution ratio of three-dimensional information including the distance, the angle and the depth can be obtained; abnormal points of a submarine pipeline can be accurately positioned through combination with data of the GPS, an ultra-short base line positioning system, the electronic compass and the CTD and through data calculation and analysis.

Description

technical field [0001] The invention relates to a submarine pipeline detection device, in particular to a submarine pipeline detection device based on an ROV platform. Background technique [0002] With the accelerated pace of exploring the ocean, people are increasingly aware that the ocean, which accounts for 75% of the earth's area, will become a new field for human survival and development, and will play an important role in human development and social progress. In recent years, the development of offshore oil and gas resources has developed rapidly. In the development of oil and gas resources, submarine oil and gas pipelines are the fastest and most economical means for long-distance transportation of oil and natural gas. Submarine pipelines have become an important part of offshore oil and gas field development projects. . During long-term use, the materials of submarine pipelines will have defects of various natures and characteristics due to various reasons. When t...
