Please note, This instructor-led course has specific dates and times:
This course is held online over 1 day on the following schedule (All times in Eastern Time Zone)
10:00 am to 6:00 pm Eastern (Will include the usual breaks and lunch)

After participating in this course you will be able to do the following:

  • Understand corrosion mechanisms for various metals, especially carbon steel
  • Describe the characteristics of cathodic protection systems (sacrificial anode and impressed current)
  • Identify the limits of each technology and their applicability
  • Understand basic code requirements (API, CSA and NACE)
  • Supervise basic cathodic protection work and maintenance

Cathodic protection is vital to ensure the integrity of numerous structures buried in the ground or concrete or immersed in water; particularly in the civil, maritime and petrochemical fields. However, basic principles are often poorly understood, leading to several problems, especially when accidents can have important impacts on health and safety or the environment.

This course will focus on the two cathodic protection technologies: sacrificial anodes and impressed current, on the criteria used to select one or the other, their inherent strength and weaknesses and on economic aspects. Furthermore, maintenance, verifications (based on industry standards) and common mistakes will be discussed through examples and case studies.

Course Outline :

  • Introduction

Nicolas Geoffroy, ing., P.Eng., Ph. D., métallurgiste

Nicolas Geoffroy, P.Eng., Ph.D., Metallurgist, holds a bachelor's degree in materials engineering and a doctorate in metallurgy from McGill University. As a Metallurgical Engineer, he carries out on-site investigations, performs simulations and laboratory testing, analyses and characterizes macroscopically and microscopically all types of material and prepares expert reports. During his years of experience in the field of materials, he took part in various projects in the aerospace, oil and gas and extractive sectors in North America and Europe. He also though at the undergraduate level at McGill University, Canada.

He has conducted laboratory testing and simulations to verify hypotheses on the nature and cause of hundreds of failures involving metallic materials. He developed a specific expertise in the corrosion and cathodic protection fields. He presently works for CEP Forensic in the Materials and Chemistry group.
