... resistance are developed. The results from several such surveys are examined to understand both the successes and challenges with this technique, as well as some of the applications in both cathodic protection system remediation and AC mitigation modeling.

... and powerline collocation AC interference AC mitigation AC risk assessments safety mitigation wire gradient control grid DC decoupler monitoring INTRODUCTION AC interference is a significant concern for pipeline operators, particularly when high voltage AC (HVAC) powerlines share right-of-way (ROW...

.... Lessons learned during the mitigation and commissioning process are intended to provide guidance to operators encountering similar conditions on their pipeline systems. AC Corrosion AC frequency AC Interference AC Mitigation Cathodic Protection Corrosion Protection INTRODUCTION A corrosion...

...As a result of continued additions and upgrades to the nearby transmission line system, the pipeline system was subject to an ever-changing profile of AC interference peaks and valleys. A traditional AC mitigation approach would begin with a detailed engineering study. The study would rely heavily...

...This paper discusses how to evaluate the risk of AC interference hazards at pipeline facilities and the different factors and strategies to consider when designing an AC mitigation system. The paper focuses the discussion on AC interference hazards within pipeline facilities and does not cover...

... and coating stress above the established limits in the unmitigated state. A shared AC mitigation system was designed to eliminate the hazards caused by AC interference on all eight pipelines. This approach reduced overall mitigation requirements, number of site visits, construction footprint, environmental...
