Challenge
Localized corrosion at river crossings and AC interference from co-located power lines. Legacy survey data was fragmented without integrated GIS mapping.
→
Solution
High-resolution DCVG, continuous CIPS, and AC/DC interference analysis. Corrosion risk mapping with coating repair prioritization. Operator training for periodic monitoring.
"PayeshCo's engineering report became the basis for our annual repair program. Field accuracy and NACE SP0502 compliance were outstanding."
