Integrity Assessment Surveys
REDOX engineers can provide detailed audits of cathodic protection systems, interference investigation or pipeline integrity assessment surveys. REDOX have completed complex evaluations of defective cathodic protection systems in plant and on pipelines. For pipelines, a complete Coating Defect Assessment Survey may include a Close Interval Potential Survey (CIPS), Direct Current Voltage Gradient Survey (DCVGS), PCM survey, soil resistivity and soil analysis to provide defect priority ranking and earmark selective coating defects for excavation and rehabilitation. REDOX also follow External Corrosion Direct Assessment (ECDA) procedures as set out in current NACE standards. These techniques produce results comparable with Inline (ILI) surveys but have the advantage of not requiring contact with the pipelines or expensive launchers/receivers
