Two leaks were found on a recently installed (1999) pipeline which was coated with extruded poly ethylene 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 pipeline integrity, and describes the challenges encountered in developing a mitigation program. The reliability of indirect inspection tools along directionally bored sections of pipe, in correlation with special soil conditions, is also discussed.
