Our Vision
To set industry benchmarks in asset integrity management by continuously enhancing the safety, reliability, and efficiency of critical infrastructure through innovative strategies and superior execution.
This field study uncovers how elevated temperatures and goethite formation at coating defects can significantly reduce AC corrosion rates—even when standard interference thresholds are exceeded.
