Proactive and Hybrid Sensing based Inline Pipeline Defects Diagnosis and Prognosis

This project will support the development of a new form of hybrid sensing technique, thermoelectromagnetic-acoustic (TEA) method that can identify and characterize injurious pipe body proactively with superior resolution and high sensitivity. The detection results from the proposed advanced nondestructive evaluation (NDE) sensing methodology are further integrated with probabilistic methods and mechanical analysis for the accurate time-dependent reliability analysis. An information fusion framework integrating the residual strength calculation, uncertainty quantification and propagation analysis, and Bayesian updating is proposed for the accurate pipeline reliability evaluation and risk assessment using NDE testing results. If successful, the pipeline failure can be significantly reduced by this innovative pipeline defects diagnosis and prognosis approach.
