Overview
EN 12495:2000 - Cathodic protection for fixed steel offshore structures (CEN) defines the accepted means to cathodically protect the submerged areas of fixed steel offshore structures and their appurtenances. The standard addresses corrosion control measures applied below waterline to extend service life and maintain integrity of jackets, platforms, piles and attached metallic equipment. National adoptions (for example SIST EN 12495:2000) reflect this European standard in local regulatory and procurement contexts.
Key Topics
The standard focuses on practical methods and requirements for effective marine cathodic protection. Key topics typically covered include:
- Scope and objectives for cathodic protection of submerged steel structures and appurtenances.
- Selection of CP systems: guidance on sacrificial (galvanic) anodes versus impressed current systems and system selection criteria.
- Materials and compatibility: requirements for materials used in anodes, electrical connections and interfaces with metallic coatings.
- Design considerations: methodology for sizing and locating CP components to protect submerged areas (general principles rather than proprietary calculations).
- Installation and commissioning: accepted practices for mounting anodes, electrical continuity checks and initial system commissioning.
- Monitoring, inspection and maintenance: recommendations for periodic potential measurements, performance verification and remedial action planning.
- Documentation and records: requirements for design records, test reports and maintenance logs to demonstrate ongoing compliance.
- Safety and environmental considerations: operational best practices to mitigate risks during installation and operation in the marine environment.
Applications
EN 12495:2000 is applied wherever fixed steel offshore structures require long-term corrosion protection below the waterline:
- Offshore oil & gas platforms (jacket legs, piles, splash zone interfaces)
- Offshore wind turbine support structures and substructures
- Fixed marine structures such as piers, jackets and submerged appurtenances
- New build design, retrofit projects and life‑extension programs
Who Uses This Standard
Primary users include:
- Corrosion engineers and cathodic protection designers
- Offshore structural and marine engineers
- Fabrication, installation and commissioning contractors
- Asset owners, operators and maintenance teams
- Inspection bodies and procurement/specification writers
Related Standards
EN 12495:2000 connects with broader European and national standards on marine structures, metallic coatings and corrosion control. National adoptions (e.g., SIST EN 12495:2000) and other EN/ISO documents covering coatings, testing and inspection are commonly referenced alongside this standard.
