Displacement Monitoring System for Submarine Pipelines during Repair*
OCEANS 2023 - Limerick(2023)
Abstract
The marine environment where submarine pipelines are located is complex, and external factors such as submarine landslides, soil liquefaction, and anchor impacts will cause damage to the mechanical structure of the pipeline, and it is inevitable to repair the pipeline. During the pipeline repair process, there are certain dangers in equipment installation, long installation duration, and difficult communication between operators, which may cause secondary damage to the pipeline. Therefore, we have studied a set of submarine pipeline displacement monitoring system, which avoids the influence of water flow and ocean environment, uses MEMS accelerometer array to obtain pipeline attitude information, and the control system transmits pipeline data to underwater acoustic communicator, and the surface acoustic communicator is online Real-time acquisition of pipeline displacement data to effectively monitor pipeline safety during repair.
