Pipelines are the most economically viable mode of transport for oil and gas companies. However, the viability is dependent upon the continuous operation of the pipeline without any unplanned shutdowns. Intelligent or smart pigging allows the pipeline operators to inspect the pipeline for anomalies like corrosion, metal loss, dent etc. without stopping the flow. Intelligent or smart PIG (Pipeline Inspection Gauge) uses sensors like Magnetic Flux Leakage or Ultrasonic to identify the anomalies. In case of long pipelines intelligent pigging is the only viable method to efficiently operate the pipeline.
