In-line-inspections (ILI) can provide reliable data that allow the current integrity of pipelines to be determined. For future integrity, the corrosion growth rates and the associated effect on the strength of the pipe are required to schedule repairs and future inspections. In this paper, a brief summary of recently developed analysis methods is given. An example is presented to show how corrosion depth and length growth rates are determined using the run comparison and statistical analysis methods to allow projection of the decrease in failure pressure that occurs between successive ILI projects, and to determine the future repairs that are required.
