This DCVG Coating Fault Survey Audit Protocol provides a structured checklist to assess pipeline coating integrity and the effectiveness of cathodic protection systems. It covers preparation and setup, connecting current interrupters to transformer rectifiers and anode ground beds, assembling and calibrating probes and meters, traversing the pipeline centerline, identifying and sizing coating holidays, pegging and recording locations, and measuring pipe-to-soil signal swing. Use this template to standardize field surveys, document findings, and confirm restoration of equipment and bonds to normal operating status. Suitable for utilities and pipeline operators managing corrosion control programs.
