The analysis of indirect inspection data is a critical factor in conducting a successful ECDA process.

This paper covers two lessons learned recently when dealing with bonded pipelines along common rights-of-way and also with equalization currents. The “old” challenge of differentiating
between “threat” related versus “tool” related indications will be also discussed.

Topics like attributing a coating holiday to the “right” pipeline in a common right-of-way, differentiating a magnesium anode profile from an equalization current signature and “double
dipping” in a DCVG indication are reviewed in detail in this paper.
