This class has met the minimum and is will be held as scheduled.

Course Objective
The objective of this two-day course is for each student to understand the basic fundamentals of AC interference and AC mitigation.

Introduction
 The Understanding Pipeline AC Interference and Mitigation course is offered as a 2-day course, ending at 3 on the second day, which 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 information and includes AC modeling and mitigation examples.

PDHs Available

Instructor Bio
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.
