Corrosion assessment criteria in current standards for onshore transmission pipelines rely on safety factors that are experience-based, with their implication on the risk or safety level associated with the pipeline unknown.
Working as part of a joint industry project, we have developed reliability-based corrosion assessment criteria in a deterministic format that are calibrated to achieve a specified safety level. The main features of the criteria are:
- Inclusion of calibrated safety factors and input parameters that result in intended reliability levels within a specified tolerance
