This training has passed.

The Cathodic Protection (CP) Design for Buried Pipelines course is offered as a 1.5-day course that covers corrosion principles and CP concepts as they apply to buried pipelines. Course topics include factors that influence CP design, CP design approach, CP design principles, CP system and materials, and CP design examples. This course utilizes a combination of theory and practical information and is designed to provide in depth coverage in the principles and concepts of pipeline CP design.  The course will provide design calculations and examples. Students are expected to have a basic knowledge of corrosion on buried structures and CP application and concepts (please see our CP Concepts and Design Principles course for basic knowledge of CP).

Who Should Attend?
Engineers, consultants, pipeline operators

Pipeline CP Design Examples

The Instructor:

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.
