Integrity Assessment Surveys

Integrity Assessment Surveys

CTS engineers can provide detailed audits of cathodic protection systems, interference investigation or pipeline integrity assessment surveys.CTS 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. CTS also follow External Corrosion Direct Assessment (ECDA) procedures as set out in current NACE standards.

Though our relationship with Speir Hunter, UK we are able to offer unique Stress Concentration Tomography (SCT) survey techniques for pipeline assessment, including non‐piggable pipelines. These techniques produce results comparable with Inline (ILI) surveys but have the advantage of not requiring contact with the pipelines or expensive launchers/receivers.
