Ensure effective corrosion control for immersed or buried metallic materials.
Key considerations for effective cathodic protection
Cathodic protection is frequently used as a secondary corrosion control or backup system in combination with protective coatings but also as a standalone system when operational conditions make coatings unjustified or impractical.
Despite a simple and robust mechanism, the protective effects of cathodic protection are only optimal within a narrow range of design and operational parameters. Faulty design or improper operation of cathodic protection may damage equipment, protective coatings and even personnel safety.
Consequently, the area of cathodic protection is regulated and requires the expertise of specialised and suitably qualified engineers.
Cathodic protection services
Impressed current cathodic protection
- Design and analysis of impressed current and sacrificial cathodic protection systems
- Offshore and onshore metallic fixed and floating structures, pipelines, tanks, jetties, quay-walls
- Reinforced concrete structures and systems for hydrogen-induced stress cracking (HISC) susceptible materials (martensitic and duplex stainless steels)
Inspections, surveys and modeling
- CP inspections and surveys (including CIPS/COPS and DCVG), including onshore CP and offshore CP
- Subsea cathodic protection surveys using cell-to-cell techniques
- Corrosion potential mapping on concrete structures
- Cathodic protection modeling, including well casings potential and current density profile modeling (using wireline tool simulation software)

Design and troubleshooting experience
Wood’s highly experienced and certified corrosion engineers have delivered a long track record of innovative cathodic protection designs and troubleshooting as well as retrofitting cathodic protection consultancy scopes. Our team of specialist metallurgists are experts in cathodic protection application techniques.
We understand the many factors that can impact the effectiveness of cathodic protection and consider influences such as hydrogen-induced cracking, stray current and electrolysis risks during project planning, eliminating or mitigating these risks during the design process. We also work to ensure that protective coatings and cathodic protection work hand-in-hand to respond to corrosion issues effectively.
