This paper summarizes all the activities carried out to evaluate the integrity of a 34-in. onshore gasline, in order to establish the best strategies to manage the gasline for the next 20 years, taking into account the future operating conditions. Three different alternatives have been considered: the first one was a new pipeline laying, the second the replacement of all damaged stroke line, more or less half of the line, and the last one was a refurbishment of the line by the removal of just the most significant defects. A cost analysis has been performed for all these alternatives. The third one has been selected on the basis of technical and economical evaluations.
