Abstract: This paper describes an efficient methodology that utilizes the first order reliability method (FORM) and system reliability approaches to evaluate the timedependent failure probabilities of a pressurized pipeline at a ...

Abstract: A loglogistic probability of ignition (POI) model for ruptures of onshore natural gas transmission pipelines is proposed in this paper. The parameters of the proposed POI model are evaluated based on a total of 188 rupture ...

Abstract: The present study proposes a new semi-empirical burst capacity model for corroded oil and gas pipelines under combined internal pressure and longitudinal compression. The proposed model evaluates the burst capacity of a ...

Abstract: In this study, the interaction effects of closely spaced corrosion defects on the burst capacity of oil and gas pipelines under combined internal pressure and longitudinal compression are investigated by using parametric ...

Abstract: This paper describes a nonhomogeneous gamma processbased model to characterize the growth of the depth of corrosion defect on oil and gas pipelines. All the parameters in the growth model are assumed to be uncertain; the ...

Abstract: A hierarchical Bayesian growth model is presented in this paper to characterize and predict the growth of individual metalloss corrosion defects on pipelines. The depth of the corrosion defects is assumed to be a powerlaw ...

Abstract: Several wellknown equations for estimating the crack length in the singleedge notched bending (SE(B)) specimens from the normalized crack mouth opening displacement (CMOD) compliance are evaluated based on twodimensional ...
