on CP and corrosion
management of multiple pipeline
right-of-ways.
E
xternal corrosion control becomes extremely
challenging for multiple pipeline corridors that
have been expanded over time with additional
facilities. Effective cathodic protection (CP)
management relies on the correct analysis of accurate field data
retrieved from each of the individual pipelines within the right-of-
way (ROW). Conventional CP survey techniques often will not provide
a sufficient level of distinction required to ascertain the adequacy of
