Intelligent pig inspection of pipelines is a necessary activity that provides critical information about the current condition of a pipe, the efficacy of the corrosion control program and the input required to predict the future safe operating conditions of the pipeline. Intelligent pigging is much like ultrasonic inspection of a pressure vessel, the inspection alone is not adequate for continued safe operation. The results from surveys must be tested by the operator to ensure they are sensible and realistic. The accuracy of the results will depend not only on the tool parameters but also on the degree and morphology of the corrosion or metal loss in the pipeline. In any event, the data that is produced provides the corrosion engineer with valuable input upon which to base his professional opinion. To guard against problems, the operator must ensure that his pipeline is piggable in accordance with the requirements of the tool he is running and that the pipeline is clean and operating under stable conditions that are within the operating conditions of the tool. He must also ensure that he discloses all operating conditions to the tool vendor (pipeline configuration, operating conditions, H2S and CO2 levels, water cut, pressures, temperatures and velocity) so that potential problems can be identified early and resolved before the supplier arrives at the worksite.
