Development of a new tool to avoid unnecessary excavation of buried gas pipelines: MobiZEN

The present paper presents initial real-scale results of the use of a new device that allows detecting whether or not active corrosion is taking place on a buried pipeline. This information is essential to decide whether or not digging up of a buried pipeline is to be scheduled. Avoiding unneeded digs and optimizing the scheduling of future digging operations may represent an important factor of cost reduction in pipeline maintenance operations.
