Audubon Companies provided an AC interference and mitigation study on the existing pipelines, located between Woodward and
Oklahoma City. The pipelines will be in collocation with two (2) proposed High Voltage AC (HVAC) overhead transmission lines,
namely MINCO4 and MINCO5. The objective of this study was to identify the level of AC interference on the existing pipelines from
the proposed MINCO4 and MINCO5 power lines under average and peak loads and to propose a conceptual design for the AC
mitigation system, for both safety and corrosion compliance.

PROJECT PROFILE
MINCO4 & MINCO5
AC MITIGATION STUDY
The following were investigated as part of this study:
▪
The risk to personal safety, under both steady-state and fault
conditions.
▪
The coating stress voltage, and pipeline integrity risk under fault
conditions.
▪
The AC corrosion risk under steady-state conditions.
▪
The risk of arcing between tower footing and the pipeline under
fault and lightning conditions, due to the proximity of the two
systems.
▪
Simulations were performed using the Elsyca IRIS software.
