External Corrosion Direct Assessment (ECDA) is a structured process used to evaluate buried onshore ferrous pipeline integrity. The ECDA goal is to enhance safety by managing the risk of pipeline corrosion failures while minimizing the cost required for excavations and repairs. ECDA may also be used when more established methods such as in-line inspection (ILI) and pressure testing are not possible or not practical.

CORRENG offers complete ECDA services, including accurate estimation of the extent of coating defects, and corrosion activity, using a fast and efficient CIPS and DCVG integrated approach with no need to interrupt the survey or return to defect locations afterwards.

Pipeline integrity services offered include:

• Development/Design of ECDA programs
• Implementation of ECDA programs
• Integrated CIPS and DCVG survey
• Review of ECDA programs
• Assessment of ECDA Data
