External Corrosion Direct Assessment (ECDA)
External Corrosion Direct Assessment is a structured, four-step methodology - pre-assessment, indirect inspection, direct examination, and post-assessment - used to evaluate and manage external corrosion on buried pipeline segments where in-line inspection tools cannot be run. The indirect inspection step uses above-ground survey techniques to identify locations where coating damage or corrosion activity is likely, prioritising them for direct examination; it is a specific, named methodology, not a generic term for "inspecting from the surface."

This is one term out of many an integrity team has to track. Sentrix turns the underlying inspection evidence into a standardised, prioritised, defensible decision - see the platform, or explore the free tools.
