The use of in-line inspection (ILI) tools and cleaning pigs is a common and successful way to manage the ongoing integrity of operational pipelines. However, even with thorough planning, in some instances these tools and pigs can become damaged or, worse still, lodged in the pipeline. Conditions that can contribute to a failed pig run include excess debris in the pipeline, unknown pipeline bends or wall thicknesses, intrusive equipment not addressed prior to the run, improper management of pumps and compressors, the style of the pig or inspection tool and incompatible valves or fittings.
