Improvements to Pipeline Assessment Methods and Models to Reduce Variance

项目名称：	Improvements to Pipeline Assessment Methods and Models to Reduce Variance
摘要：	This project will develop, validate, and demonstrate improved assessment methods and models to lower the variance of model outputs when assessing the impact of interactive threats. This project will provide general knowledge, models, and methods pertaining to the assessment of overlapping defects in natural gas pipelines not currently available. The project deliverables will be directly applicable to fitness-for-service standards. Extensive use will be made of multi-physics modeling to quantify the uncertainties associated with material property variations, interacting threats, overlapping defects and the various non-destructive evaluation methods available to the operators. Bayesian methods will be used to merge multiple data streams to reduce uncertainties associated with pipeline assessment. Limited full-scale pipe testing will be conducted to validate simulation results and material testing will be conducted to validate the advanced failure propagation models employed in the finite element method analyses.
