State-of-the-Art Review on Existing Repair Techniques for Damaged Pipelines

In 2000, the EPRG Workshop on Fitness for Purpose identified a need for a state-of-the-art review on repair techniques for pipelines, focused on the limitations of existing repair techniques, in order to allow the EPRG Design Committee to assess the potential need for further work. The review consisted of four steps: • Definition of a functional specification and of the criteria to meet this specification. • Literature review on existing repair techniques. • Analysis of limitations of existing repair techniques. • Recommendations for future developments. This paper is based on the EPRG report [3] which ended the review. It summarizes the findings of the detailed review of ten repair techniques which were analyzed using the format of the technical specification sheet that was agreed by the Committee.
