Submarine oil and gas pipelines, as an important lifeline for the transportation of marine oil and gas resources, undertake the important responsibility of transporting marine oil and gas resources due to their economical convenience, safety and reliability. The laying of marine pipeline (MP) in the dark and humid harsh environment such as the seabed is easy to It is very meaningful to conduct regular inspections on submarine oil and gas pipelines from the perspective of economic development and environmental protection. Therefore, this paper studies the MP based on the positioning analysis method. This paper firstly analyzes the relevant factors of corrosion of MP and briefly explains the detection principle of acoustic emission detection technology. Then, it discusses the low-frequency locator launching system, node position detection and pipeline fatigue crack detection of MP. Finally, It is the positioning and repair of MP.
