NACE Cathodic Protection Specialist – CP4 Preparation Course

• Corrosion and cathodic protection engineers

• Integrity and corrosion management specialists

• Pipeline, tank farm, and offshore maintenance engineers

• Senior inspectors and technical authorities in asset protection

Prior completion of intermediate-level cathodic protection training or equivalent field experience is recommended. Participants should be familiar with CP fundamentals, reference electrodes, current distribution, and ISO/NACE/EN standard frameworks.

• Advanced electrochemical behavior of buried and submerged metals — polarization curves, IR-drop separation, mixed potential theory

• Design logic for impressed current systems — current demand calculation, anode spacing, cable sizing, rectifier selection, redundancy

• Deep anode beds — drilling constraints, venting design, backfill selection, gas block risks, commissioning tests

• CP for offshore assets — sacrificial vs. ICCP criteria, current shielding by marine growth, splash zone considerations, retrofits

• CP of storage tanks — bottom plate protection (new/existing), ring anodes, dielectric isolation, high-resistivity soils, CP-coating interaction

• Buried pipelines — interference from parallel utilities/rail, casing isolation, AC corrosion, DC stray current mapping, mitigation strategies

• Stray current and interference engineering — sources (DC traction, foreign pipeline crossing), coupons, bonds, drain points, test station logic

• Measurement & diagnostics — reference electrode placement errors, ON/OFF technique, close interval surveys (CIS), DCVG/PCM integration

• Failure case analysis — shielding under disbonded coating, under-protection, over-protection consequences, hydrogen-induced issues

• Standards & compliance — interpreting ISO, EN, AMPP criteria without overdesign, audit preparation, documentation essentials

• Integration with integrity programs — alignment with coating QCs, RBI/inspection windows, long-term monitoring and data trending

• Lifecycle & optimization — CP asset aging, anode consumption forecasting, economic justification of retrofit versus re-coating
