Does reliability-based corrosion assessment criteria reduce risk?

Corrosion mitigation for pipelines, vintage pipelines in particular, has a significant effect on the industry’s management systems and related costs. To help optimize the corrosion management process, deterministic reliability-based corrosion assessment criteria have been developed for onshore pipelines as part of a joint industry project.

We worked with TransCanada Pipelines to evaluate the assessment criteria to determine if they lead to reasonable corrosion management decisions and compare well to other deterministic and probabilistic criteria. The evaluation involved applying the criteria to 22 transmission pipeline cases and comparing the results to those of:

  • CSA Z662 deterministic criteria
  • TransCanada Pipelines’ full probabilistic reliability-based criteria

Riski Adianto is presenting the results of this project at the upcoming International Pipeline Conference in Calgary, Alberta on September 25, 2018 at 1:30 p.m. to 5:00 p.m. The presentation will be in McLeod Hall C. You will learn about the effects of the reliability-based corrosion assessment criteria on the calculation of corrosion repairs.

The entire paper – "Implementation of Reliability-based Criteria for Corrosion Assessment" - is available through the 2018 International Pipeline Conference.

Riski Adianto is a Research Engineering in the Integrity & Operations department at C-FER. His focus is the quantitative risk and reliability analysis of pipelines.
