Results
 For many normally dry gas systems, the availability of comprehensive
historical operating information required by the DOT 192 SubPart
O regulation to demonstrate the absence of an Internal Corrosion
(IC) threat is scarce.
The absence of leaks associated with internal corrosion is
not enough to conclude Internal Corrosion is not a threat.
This lack of data has lead to risk models using default (or
worst case) conditions, yielding an increased IC risk potential.
Robust ICDA Programs address:
- Is the threat of Internal Corrosion likely (more so than
just a potential)?
- Do I have a clearly defined, repeatable, well documented process?
- How do I calculate and locate critical internal corrosion
sites?
- What inspection process will I use to confirm the presence/absence
of corrosion?
- What if I find corrosion – what level of corrosion requires
remediation?
- How do I determine reinspection intervals?
- How do I select, install, and evaluate an Internal Corrosion
Monitoring Program?
