• Alignment of repeat inspection data by normalizing it to common reference points (e.g., girth welds).
  • Automatic feature matching process, resulting in calculated corrosion growth rates between inspection intervals.
  • Raw signal data comparison, to validate the calculated growth rates based on feature matching.
  • Feature resizing (where required) of selected features conducted by data analysts to further validate corrosion growth rates.
  • Matching of other reported features (e.g., dents) to deter-mine possible pipeline damage between inspections.
