Corrosion assessment criteria in current standards for onshore transmission pipelines rely on safety factors that are experience-based, with unknown implications on the risk or safety level associated with the pipeline.
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;
- Consideration of two failure modes: burst and small leak; and
- Easy-to-use due to its deterministic nature.
Riski Adianto is presenting the results of this project at the upcoming International Pipeline Conference in Calgary, Alberta on September 28, 2018 at 8:30 AM to 12:00 PM. The presentation will be in Telus McLeod E1. You will learn about the development of the reliability-based corrosion assessment criteria and the broad range of pipeline designs and corrosion conditions it can be applied to.
The entire paper – “Development of Reliability-based Criteria for Corrosion Assessment” – is available through the 2018 International Pipeline Conference.
To learn about the practical implications of the application of this criteria, please see “Does reliability-based corrosion assessment criteria reduce risk“?
