In the framework of a research project aimed at the application of corrosion modelling in field
operation, a few cases of internal corrosion observed in pipelines were studied.
While it is reasonably easy to understand a corrosion event 'retrospectively" with failure analysis
methods, a large degree of uncertainty is associated with the attempt of quantifying a prediction for
future damages.
Corrosion models should be implemented taking into account that conditions do change during
time (fluid composition and properties, temperature, pressure ...) and in space (change of flow
regime and physical parameters along the line).
