Pipeline leak detection system and method based on the submarine underwater unmanned vehicles

Detection systems and methods of the present invention discloses a subsea pipeline unmanned underwater vehicle based on the leak, the system is based on the detection by the subsystem Vehicle unmanned autonomous underwater vehicles and detection subsystems. Wherein unmanned autonomous navigation based on the detection of an unmanned autonomous subsystems include aircraft and mounted on the autonomous unmanned aircraft conduit and spill position detecting module detecting module, for implementing a wide range of rapid inspection. Based on the detection subsystem comprises AUV underwater robots, umbilical retractable module, control module, and the water is mounted on the ROV to accurately detect the position of the pipeline and oil spill module accurate detection module for detecting the position of the pipe to achieve high precision positioning and accurately detect small leaks. The system detects speed, low cost, to meet the security needs of offshore oil production.
