Abstract: Assessing pipeline integrity includes deploying vibration sensors at optimal sensing locations in the pipeline network. The sensors communicate with an analyzer via an intermediary that is a local or a remote wireless controller. A sensor records and processes vibration signals regularly, according to protocols kept in the memory of the sensor. The sensor, via a controller, communicates recorded data or processed data to an analyzer and receives updated protocols or other instructions from an analyzer. The analyzer aggregates recorded and processed data from the sensors, which are then analyzed to detect or localize leak sounds from the pipeline network. The recorded data from two or more sensors may be time-aligned using synchronization methods.
