Hidden Integrity threats that go undetected can result in compromised cathodic protection that may lead to pipeline leaks.This paper will discuss three hidden integrity threats that were discovered using an in-line pipeline inspection tool designed to measure cathodic protection current movement along the line. Conventional above grade cathodic protection survey methods failed to detect potentially serious issues on three pipeline systems.The current measurement in-line inspection process data analysisand findings will be discussed for three separate pipeline projects where conventional above grade cathodic protection testing methodologies failed to locate the threats hidden on the pipelines.

Key words: Cathodic Protection, CP, CP Rectifier, CP Bond, Undocumented Bond, AC, AC Potentials, CPC-ILI, Cathodic Protection Current In-Line Inspection, CP surveys, Corrosion Control, Pipeline Integrity, In-Line Inspection, CP Current, CP Current Density
