Cathodic Protection Marine ISO Level 3 / 2025
Why attend this course?
This course and examination is in compliance with ISO 15257:2017 and is suitable for candidates with ICorr Level 2 Cathodic Protection Technician certificate in Marine Metallic Structures, or who have at least one year of approved experience and attended a Level 2 training course to satisfy the educational and experience requirements set out in ICorr QPD.
Do you need to be certified?
If you work in cathodic protection, you must be certified as competent to do so. This applies around the world, and the Institute of Corrosion has upgraded its courses to fully meet the requirements of the rewritten cathodic protection competence standard – BS EN ISO 15257:2017. At each competence level you must apply to the Institute of Corrosion for certification. Go to the Downloads tab to find the relevant application form for Certification.
Level 3 Senior Technician:
This is the minimal level required for supervisory roles, technical inspection and those who assist design engineers.
At Level 3, you will demonstrate that you have knowledge of the:
- General principles of corrosion and CP
- Principles of electricity
