In recent years, effective techniques have been developed for conducting integrity assessments along cross-country pipelines.  In order to provide similar confidence in facility integrity, it was proposed to apply a modified external corrosion direct assessment process to a small station.  Until now, congested facility environments […]

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 […]

The analysis of indirect inspection data is a critical factor in conducting a successful External Corrosion Direct Assessment (ECDA) process. Any “out of range” data must be validated prior to being con­sidered an ECDA indication. Furthermore, standard methods of validating the accuracy of the field […]

Two leaks were found on a recently installed (1999) pipeline which was coated with extruded polyethylene and protected with directly connected magnesium anodes. This paper describes the use of external corrosion direct assessment (ECDA) principles to identify locations where corrosion could pose a threat to […]
