Once the natural gas pipeline in the water body fails, the pipeline is leaked or broken, and huge economic loss is directly caused to enterprises. Gas leakage is easy to cause fire and even explosion accidents, not only influences the surrounding water environment, but also causes certain casualties and property loss to surrounding fishery, ships, operators and the like. The natural gas pipeline accident is usually the leakage, perforation or fracture, and in the Mima oil and gas pipeline project built in 2013, the pipeline crosses 56 places in large and medium water, thereby further promoting the attention of the industry on the safe operation of the pipeline.
