Pipeline integrity management requires corrosion growth rate calculations that must be derived from consecutive external corrosion direct and inline inspections. This conventional approach is based on indirect measurements (structure-to-electrolyte potentials) and post-mortem (excavations, feature mapping) assessments limiting an operator's capabilities for proactive maintenance in a most cost-effective and timely manner.
With the increasing amount of high-voltage power line corridors, pipeline crossings, and transit systems, interference threats on pipeline assets are more common. This result sin a higher risk of accelerated corrosion with poor notification to the pipeline operator, as third-party operational conditions may unexpectedly change.
