ITN GW4SHM: ESR 7 - Reliability Assessment for Guided Wave-based Structural Health Monitoring of Pipeline Systems

Reliability in NDT is demonstrated through the Probability of Detection (POD) metric, representing the smallest damage size that an NDT system can probably detect with a 95 % confident bound. This probability is computed by statistically analyzing a significant number of inspections. The demonstration of the performance of an SHM system is a critical aspect in the maturation of SHM and is currently one of the missing links toward standardization and certification. The concept of POD has not yet been extended to integrate all the specific constraints of SHM: the fixed installation of sensors, the large area under inspection, the aging of the sensor, and the inspection under varying environmental and operational conditions. All these SHM-specific constraints emphasize the need for a novel and dedicated framework to compute a metric demonstrating the performances and reliability of a GW-SHM system. This project aims to increase the usage of guided wave-based SHM systems by improving methods for assessing reliability and standardization. Therefore, quantification of location dependency for the reliability assessment of the GW-SHM system is necessary. Particular focus is on pipeline systems in the petrochemical industry, civil infrastructure, and oil and gas industry, considering technical hot spots for particular damage types. A combination of experimental and simulated-based data on damage types is necessary to enable adequate information output, like the well-known output of NDT procedures, POD, and the most recent Model-Assisted POD (MAPOD) approach. Moreover, different signal processing methods need to be investigated regarding the influence on reliability assessment.
