Resisting rust

Over a 30-year asset life, corrosion can evolve into a structural, electrical, and fire safety issue. Corrosion drives up operations and maintenance (O&M) costs, reduces resilience to extreme events, and in some cases, can force premature decommissioning or complete structural replacement Intertek CEA’s Nicholas Hudson and Ankil Sanghvi advise on best practices.
