Reliability of pipelines under spatially varying corrosion defects


Project Description

The integrity of pipelines is greatly affected by the initiation and progression of corrosion defects. It has been widely recognised that random variations in these characteristics can be rationally quantified with probabilistic approaches. Reliability computations considering a single corrosion defect are commonly adopted with widely accepted burst pressure performance models. However, in the case of interacting corrosion defects, an appropriate framework needs to be developed to assess the inherent reliability. This is further complicated by the spatiotemporal variations of this process. Current studies to consider these effects are limited by the lack of experimentally validated models. The aim of this project is to develop spatial variability models of corrosion defects to improve the reliability estimates of pipelines, leading to effective risk mitigation.

Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Mechanical / Civil / Aerospace engineering.

Knowledge of: Structural mechanics, numerical analysis, computer programming, structural reliability, risk analysis.
