David Willoughby will present “Pipeline AC Interference and Mitigation” on November 9, 2022
This course is appropriate for pipeline, utility, and consulting engineers and other technical individuals with the responsibility of AC interference control on pipelines.
The AC Interference and Mitigation webinar is offered as a 6.5-hour course that covers the principles of AC interference and mitigation on pipelines. This course addresses the basics of AC circuits, AC interference, how to predict the effects of the AC interference on pipelines, and current methods and equipment used in AC mitigation. Course topics include the basic principles of AC circuits, induced AC pipeline voltages, shock hazards, AC corrosion, fault conditions, AC modeling, AC mitigation, and AC measurement techniques. This course utilizes a combination of theory and practical.
The objective of this course is for each student to understand the fundamentals of AC interference and AC modeling and mitigation. The webinar is designed to provide the student with knowledge of AC interference and mitigation design.

David A. Willoughby, RK&K Director, Energy & Corrosion (ret)
Mr. Willoughby has 40 years of experience in engineering, pipeline design, corrosion control, and management in the petroleum and utilities pipeline industry. His experience includes gas transmission and distribution systems, petroleum facilities, and water/sewer pipelines from conception through design, construction and testing, economic evaluation, and project field supervision. Mr. Willoughby has been responsible for the design, permitting, inspection, and construction administration of numerous horizontal directional drills (HDD) on pipeline projects. Mr. Willoughby is author of several articles and two books published by McGraw-Hill; Plastic Piping Handbook, 2002, and Horizontal Directional Drilling, 2005.
Mr. Willoughby provides HDD training to the pipeline and utility industries. He has presented HDD training to the engineering workshop at the N.C. Utilities Commission Office of Pipeline Safety Conference, Southern Gas Association Annual Conference and teaches several HDD programs a year for a broad list of clients such as Equitable Resources, Dominion Energy, FERC, National Gas Company of Trinidad, Public Service of NC, Exxon Pipeline, Shell Oil, Atlanta Gas and Light, Dominion Transmission, Columbia Gas Transmission, Colonial Pipeline, Questar Gas Company, Kansas Gas Services, HT Engineering, etc. Mr. Willoughby’s HDD training is used to provide Professional Development Hours (PDU) for professional engineers in many states, including Texas.
