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 ...
