Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of submarine pipeline detection, and particularly relates to a rapid oil pipeline detection device suitable for complex sea areas. BACKGROUND

[0002] Energy is one of the necessary topics of current social development, and marine engineering has been further developed, especially marine oil resources. The ocean has become one of the main sources of future oil production. Submarine pipelines are an indispensable part of marine oil and gas development. However, submarine pipelines are located in a harsh environment on the seabed. On the one hand, they bear high internal temperature and pressure loads, and on the other hand, they bear low external temperature loads, hydrostatic pressure, and wave current dynamic loads. Due to these reasons, submarine pipelines cannot avoid damage accumulation, deformation buckling, and other situations during service, thereby causing accidents. Therefore, ensuring the safety, stability, and reliability of submarine pipelines is crucial for the economic interests and life and property safety of the country and the people.

[0003] Currently, submarine pipeline detection operations include in-pipe detection and out-of-pipe detection. Although in-pipe detection technology can obtain information such as pipeline inner wall corrosion damage, inner wall cracks, wall thickness, and ovality, it cannot accurately describe deformation defects of the pipeline outer wall, making it difficult to perform clamp setting operations. Although out-of-pipe detection can solve the above problems, out-of-pipe detection faces problems such as water flow impact in complex sea areas, resulting in unstable combination of existing engineering equipment and submarine pipelines, especially for pipelines in complex sea areas with low visibility, thereby affecting the detection effect.
