Course Overview

The Cathodic Protection Systems Training Course provides a comprehensive and practical understanding of cathodic protection principles, system design, installation, operation, monitoring, inspection, and maintenance for industrial assets exposed to corrosion. The course focuses on how electrochemical protection methods can be applied to reduce corrosion of metallic structures and extend asset service life while supporting integrity, reliability, safety, and maintenance objectives. Cathodic protection is an important corrosion control technology for buried, submerged, and other metallic assets operating in aggressive environments. It is commonly applied to pipelines, storage tanks, marine structures, offshore facilities, water systems, underground structures, and selected process equipment. Effective protection requires more than installing an anode or rectifier; it requires understanding electrochemical behavior, environmental conditions, coating performance, current distribution, electrical continuity, interference, monitoring requirements, and system performance. The course covers the two principal cathodic protection approaches: galvanic sacrificial anode systems and impressed current cathodic protection systems. Participants will examine electrochemical fundamentals, electrode potentials, anode selection, rectifiers, reference electrodes, test stations, cables, isolation devices, coatings, current requirements, grounding and interference considerations, and protection criteria. Particular attention is given to practical system assessment, measurement interpretation, troubleshooting, and maintenance. A strong emphasis is placed on integrating cathodic protection with broader corrosion management and asset integrity programs. Participants will learn how to evaluate system performance, interpret potential and current measurements, identify under-protected and over-protected areas, investigate abnormal readings, assess coating and anode performance, and develop monitoring and maintenance programs. The course supports more effective corrosion prevention decisions and helps organizations improve the reliability and long-term integrity of critical metallic assets.

Learning Objectives

  • Analyze the electrochemical principles underlying cathodic protection and explain their relevance to corrosion control during the course.
  • Identify the main components, configurations, and applications of galvanic and impressed current cathodic protection systems.
  • Evaluate soil, water, electrolyte, coating, temperature, and environmental conditions that influence cathodic protection performance.
  • Apply appropriate criteria for selecting sacrificial anodes, impressed current anodes, reference electrodes, rectifiers, cables, and associated system components.
  • Assess current requirements, potential distribution, electrical continuity, isolation, and other factors affecting system effectiveness.
  • Evaluate cathodic protection measurements and interpret structure-to-electrolyte potential and current data.
  • Identify conditions associated with under-protection, over-protection, coating deterioration, anode depletion, electrical faults, and interference.
  • Develop inspection, testing, monitoring, and maintenance strategies for cathodic protection systems.
  • Apply systematic troubleshooting methods to investigate abnormal cathodic protection readings and system performance.
  • Assess the interaction between protective coatings and cathodic protection and identify opportunities to improve overall corrosion control.
  • Strengthen coordination between corrosion, inspection, engineering, maintenance, operations, and asset integrity teams responsible for protected assets.
  • Develop a practical cathodic protection management and monitoring plan for a selected industrial asset by the end of the course.

Who Should Attend

The Cathodic Protection Systems Training Course is designed for professionals responsible for corrosion control, asset integrity, inspection, engineering, maintenance, reliability, and the operation of metallic infrastructure. It is particularly suitable for corrosion engineers, materials engineers, cathodic protection specialists, inspection engineers, asset integrity engineers, pipeline engineers, mechanical engineers, electrical engineers, maintenance engineers, reliability engineers, and technical specialists involved in corrosion prevention and monitoring. The course is also relevant to inspection managers, corrosion managers, asset integrity managers, engineering managers, maintenance managers, pipeline managers, reliability managers, and supervisors responsible for underground and submerged assets. Professionals working with pipelines, storage tanks, marine structures, offshore facilities, water infrastructure, buried metallic structures, process facilities, and other assets requiring corrosion protection will benefit from the program. The course is also valuable for project engineers, technical authorities, asset owners, procurement professionals, and decision makers involved in specifying, designing, installing, commissioning, operating, inspecting, or maintaining cathodic protection systems. It supports multidisciplinary teams seeking to establish consistent approaches to corrosion control, system performance evaluation, inspection planning, and long-term asset integrity management.
