A method for dealing with uncertainties in in-line inspection (ILI) information has been applied to a segment of corroded line in the gas-transmission system of Transportadora de Gas del Norte (TGN) in Argentina.
Results of applying the method indicate that the safety factor for ILI data is equivalent to that provided by a hydrostatic test.
The methods consist of combining the mean and dispersion of corrosion-defect depth (d) and length (L) data and simulating the effect of these variations on calculations for failu...
