Remaining Useful Life (RUL) of Corroding Pipelines

摘要

The purpose of this paper is to develop, test, and illustrate a simplespreadsheet-based probabilistic procedure that can be used by practicingengineers to determine the remaining useful life (RUL) of pipelines. Thesuggested reliability assessment together with a suitable linear, or nonlinear,time dependent wall thinning relationship can be used todetermine the failure probability as a function of years in service. DNVF101, FITNET FFS and ASME B31G, are used to demonstrate themethod, which also permit to compare and contrast results. Accuracy ofthe proposed approach is proved by replicating results from publishedliterature.
