Abstract

The invention discloses a deep sea submarine pipeline inspection system and an operation method thereof. The inspection system comprises an administrator operation terminal, a GIS database, a core server, a gateway, a mobile communication base station and a remote control submersible inspecting instrument. The remote control submersible inspecting instrument is composed of an optical imaging system, a master controller, a GPS module, a depthometer, an altimeter, a liquid crystal display module, an acoustic imaging system, a storage module, a fiber-optic gyroscope, a compass and a network communication module. The operation method of the system comprises the following steps of (1) generation of an inspection task list, (2) generation of route details, (3) inspection task execution, (4) inspection defect recording and (5) defect eliminating recording.

Description

technical field [0001] The invention relates to the technical field of pipeline inspection, in particular to a deep-sea submarine pipeline inspection system. Background technique [0002] The construction of my country's submarine oil and gas pipelines has gradually entered a peak period. Companies such as PetroChina, CNOOC, and Sinopec have built hundreds of kilometers of submarine pipelines in the Bohai Bay alone. Submarine pipelines are marine projects with high investment and high risks. Compared with land pipelines, submarine pipelines face complex and changeable marine environments, and are affected by natural factors such as wind waves, ocean currents, and storm surges, as well as human factors such as sand mining and anchor damage. , prone to safety hazards such as exposed pipelines and suspended spans. Submarine pipelines are suspended and exposed for a long time. Under the impact of wind, waves and ocean currents, they are prone to fatigue fractures. disasters, an...
