Standard Reliability-based Approach vs Bayesian Network Approach for Integrity Management

A feasibility study was conducted to identify an approach to estimate the probability of leak due to internal stress corrosion cracking (iSCC) that uses previous investigations and handles data gaps. A standard reliability-based approach and a Bayesian Network approach were compared based on:

• Effective use of data;
• Flexibility of framework; and
• Ability to improve outcomes based on additional information.

The paper— Comparison of Feasibility of a Standard Reliability-based Approach and A Bayesian Network Approach for Integrity Management of a Northern Canadian Liquids Pipeline —describes the:

• Standard reliability-based approach;
• Bayesian Network approach;
• Criteria for the comparison of the two approaches; and
• Comparison results.

Dr. Smitha Koduru is presenting the results of this project at the upcoming Virtual International Pipeline Conference on September 29 at 11:00 a.m. You will learn about how a hybrid of the standard reliability-based approach and the Bayesian Network approach can be used to develop a comprehensive integrity management tool.

The entire paper—IPC2020-9504 Comparison of Feasibility of a Standard Reliability-based Approach and A Bayesian Network Approach for Integrity Management of a Northern Canadian Liquids Pipeline —is available through the 2020 International Pipeline Conference.

Dr. Smitha Koduru is the Manager of C-FER’s Pipeline Integrity and Operations department. Her focus is on risk assessment and detailed analyses of structural systems.
