Course description

The Cathodic Protection Technologist certification indicates knowledge of theoretical concepts and practical application of cathodic protection with a strong focus on interpretation of cathodic protection data, and cathodic protection troubleshooting. This certification is designed for individuals with a heavy engineering/scientific background and extensive working knowledge of cathodic protection, or who have extensive years of field experience with some technical background. The Cathodic Protection Technologist course builds on the technology presented in the Cathodic Protection Technician course with a strong focus on interpretation of CP data, trouble shooting and migration of problems that arise in both galvanic and impressed current systems, including design calculations for these systems. Classroom instruction is comprised of lectures and hands-on training, including using equipment and instruments for CP testing.

 

Audience

This program is intended for persons with extensive field experience and a strong CP technical knowledge who need an understanding of CP design procedures based on an improved knowledge of CP concepts.

Prerequisites
