The model errors associated with five representative burst pressure prediction models, namely B31G, B31G Modified, DNV, PCORRC and RSTRENG, for corroded pipelines are evaluated based on a relatively large number full-scale burst tests on corroded pipes reported in the literature. All the test specimens in the database contain single isolated real corrosion defects. The means, coefficients of variation (COVs) and probability distribution of the model errors for the considered burst capacity models are derived based on the test-to-predicted burst pressure ratios for the collected test data. A numerical example is used to illustrate the impact of the model error on the probability of burst of the corroding pipeline.
