COURSE OVERVIEW:

The discipline of cathodic protection serves as a fundamental pillar in the preservation of metallic infrastructure, specifically designed to mitigate the electrochemical processes that lead to material degradation. This course provides a comprehensive examination of the theoretical foundations and practical applications required to suppress corrosion by making the protected structure the cathode of an electrochemical cell. By exploring the fundamental relationship between electrolyte resistivity and current demand, participants will gain a technical understanding of how protective currents are distributed across diverse engineering assets.

The scope of this training extends from the initial site survey and soil resistivity measurement to the final commissioning of complex protection systems. It encompasses the detailed engineering required for both Galvanic Anodic Systems and Impressed Current Cathodic Protection (ICCP), focusing on the selection of appropriate materials and the calculation of system life cycles. Participants will analyze the environmental variables, such as moisture content and chemical composition of the surrounding medium, which dictate the efficiency and longevity of the cathodic protection installation.

Coverage includes a rigorous review of international standards and the specific equipment utilized in the field, ranging from transformer rectifiers to reference electrodes. The curriculum addresses the critical performance criteria necessary to verify system effectiveness, including polarized potential measurements and the management of interference currents. Through technical analysis and design exercises, the course ensures that engineering professionals can develop robust solutions that comply with safety regulations while extending the operational life of critical industrial infrastructure.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Identify the fundamental electrochemical reactions and thermodynamic principles governing the corrosion process in buried and submerged structures.
2. Distinguish between the operational mechanisms and application limits of Sacrificial Anode and Impressed Current Cathodic Protection systems.
3. Conduct comprehensive soil resistivity surveys using the Wenner Four-Pin method and interpret the resulting data for design accuracy.
4. Calculate the total current requirement for a structure based on surface area, coating efficiency, and environmental current density factors.
5. Select appropriate anode materials, such as High Silicon Cast Iron, Mixed Metal Oxide, or Magnesium, based on electrolyte characteristics.
6. Design groundbed configurations, including deep well and shallow vertical or horizontal layouts, to optimize current distribution.
7. Specify technical requirements for transformer rectifiers and solar power units used in Impressed Current systems.
8. Apply NACE and ISO criteria for protection, specifically the -850 mV CSE polarized potential and the 100 mV polarization shift methods.
9. Assess the impact of stray current interference from external DC sources and design effective mitigation strategies.
10. Evaluate the compatibility between different types of protective coatings and cathodic protection to prevent cathodic disbondment.
11. Perform voltage drop (IR drop) calculations and utilize specialized techniques like Instant-Off readings to ensure accurate potential measurement.
12. Develop comprehensive maintenance and monitoring schedules to verify the continued integrity and performance of the installed system.

TARGET AUDIENCE:

This course is specifically designed for corrosion engineers, asset integrity managers, pipeline design engineers, maintenance supervisors, and technical personnel responsible for the design, installation, and oversight of cathodic protection systems in the oil, gas, and water sectors.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
