- CCDs define how equipment can degrade and howthat degradation is controlled.
- IOWs define the operating limitsrequired to prevent or minimize that degradation.
They are widely associated — Damage Mechanisms
- API RP 970 — Corrosion Control Documents
- API RP 584 — Integrity Operating Windows
- API 580/581 — Risk-Based Inspection (RBI)
Corrosion Control Document (CCD) is a structured technical document that identifies:
-damage mechanisms affecting equipment,
- causes of degradation,
- vulnerable circuits/components,
- monitoring requirements,
- inspection strategies,
- materials limitations,
- operatingconstraints,
- and mitigation measures.
