Are Pipeline Operators Over-Relying on the In-Line Inspection?

Abstract In-line inspection (ILI) is a rapidly evolving field that leverages advancements in inspection technologies, software development, and miniaturization of electronic components to create more accurate, robust, and autonomous tools. These advancements have expanded the capabilities of ILI systems to detect, identify, and size a wider range of pipeline anomalies, and to overcome many other previous limitations. However, factors such as regulatory requirements, cost considerations, and, sometimes, lack of competency on risk management, have led to an increasing reliance on ILI data as the primary input for managing the corrosion control barriers, which is slowly but steadily leading to a reactive approach to pipeline integrity management. This paper examines the critical role that risk assessment (RA) plays in preserving the pipeline’s integrity and how overreliance on ILI for corrosion management can undermine this function. The paper advocates for a balanced approach that integrates ILI with robust RA to ensure the proactive management of corrosion threats.
