An AC interference study and mitigation design was performed for a pipe replacement project. The project was broken up into multiple phases due to a construction schedule that spans multiple years. This paper is a case study examining the process of performing a piece-wise vs a holistic mitigation design for the pipeline. Designs are based on field data and software modeling. Designs for each approach are compared and their differences and benefits are explored.
