Abstract	In-line inspection (ILI) gives pipeline operators a snapshot of the condition of their pipelines. Unfortunately, accuracy limitations exist with all ILI tools. It is therefore judicious for pipeline operators to support their pipeline integrity maintenance planning by employing Probability of Exceedance (POE) methodology that accounts for the inexact nature of the ILI data. A new method is needed that can be used to assist pipeline operators make rational and defensible integrity decision when faced with very poor pipeline conditions with numerous interacting metal loss defects. The normal method of using RSTRENG with Monte Carlo Simulation (MC) for probabilistic assessment of corroded pipeline pressure is unsuitable and unmanageable. The new method employs DNV-RP-F101 with Point Estimate Method (PE) and the MC to efficiently apply the POE methodology to severely corroded pipelines.
