For pipelines with successive ILI runs the detected population of corrosion defects can be compared to identify both internal and external corrosion growth. Depending on the number of defects to be compared, the assessment can demand significant effort and expertise to ensure accurate and meaningful correlations between often very large ILI data...

A natural gas leakage was detected on the unpiggable high-pressure DN 600 pipeline Kasejovice – Mikulášov in Czech Republic after 50 years of operation. The pipeline was excavated and found to suffer from extensive corrosion; corrosion of a similar extent was also found when another section of the pipeline was excavated on the same location. The...

Pipeline inspection using intelligent pigs is currently the safest and most reliable way to detect relevant defects, to plan repairs and maintenance and to calculate the pipeline lifetime. However, there are still many pipeline systems on- and offshore which were never designed and built for conventional ILI tools and modifications would be...

Particularly in the 1940s and 1950s, gas pipeline systems were not necessarily designed and built with inline inspection in mind. As a result, mechanical configurations are encountered that cannot be inspected with currently available inspection equipment. Furthermore, operators are trying to reduce capital and operational expenses by merging...
