Practical evaluation of inline inspection methods for large prestressed concrete transport pipelines

Monitoring of Waternet’s large diameter transport pipelines includes the main failure mechanisms: breakage of prestressing wires and joint leaks. New inline inspection tools have the potential to increase availability and safety, but validation in full-scale conditions is necessary. In this article, we present a practical validation of two inline freeswimming inspection tools for acoustic leak detection (SmartBall®), joint gap measurement with laser scan and electromagnetic wire breaks detection (PipeDiver®).
