David Willoughby will present “Cathodic Protection System Design for Buried Pipelines,” as a webinar on June 22, 2021

This class has the minimum to be held with seats still available.

The Cathodic Protection (CP) System Design for Buried Pipelines course is offered as a 6.5-hour course that covers corrosion principles and CP concepts as they apply to buried pipelines. Course topics include factors that influence CP design, pipeline CP design approach, pipeline 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.

Course Objective:

The objective of this course is for each student to understand the fundamentals of CP design for buried pipelines. The Course is designed to provide the student with an in-depth knowledge of CP design principles, concepts, and methods. The course provides examples of CP design and calculations. 

Target Audience:

Pipeline, utility, and consulting engineers with a desire to obtain training for CP design on buried pipelines. This course is designed to provide corrosion training to engineers so they can demonstrate a thorough knowledge of corrosion of engineering and mathematics and qualify them to engage in the practice of CP design for buried pipelines. This class is will assist engineers in meeting the requirements for CP design stated in many RFP’s and government regulations that state that the CP engineer must be accredited or certified by NACE International as a NACE Accredited Corrosion Specialist or a NACE certified Cathodic Protection (CP) Specialist or be a professional engineer who has certification or licensing that includes education and experience in corrosion control of buried or submerged metallic piping and tank systems.
