A new publication from Abraham Mensah and Srinivas Sriramula providing a comprehensive understanding of the performance of corroded pipelines with interacting corrosion cluster defects is now available to read online.

The paper ‘Stochastic finite element-based reliability of corroded pipelines with interacting corrosion clusters’ considers a realistic representation with stochastic spatial variability and implicit failure considerations to guide risk-based maintenance and management.

Published in journal Process Safety and Environmental Protection under the Risk Assessment and Reliability Engineering Section, the paper has developed a computationally efficient, stochastic-based modelling framework that addresses the complexities associated with the uncertainty of quantification and performance estimation approaches for corroded pipelines with interacting corrosion cluster defects.

The developed frameworks produce better reliability results than existing methods. Hence, this leads to relatively lesser risk and maintenance-based interventions, resulting in comparatively smaller operating expenditure in a timely manner. The developed frameworks are applicable to complex structures where explicit limit state function may not be available.

Abraham’s PhD is funded by Ghana National Petroleum Corporation supported by The National Decommissioning Centre and Net Zero Technology Centre.

Abraham is due to graduate in summer 24.
