New Defects Between Inspections and Their Spatial Features
Résumé
This chapter presents the results of new corrosion points based on the framework proposed in Chap. 7. This framework uses two consecutive inspections in a matching process to classify the corrosion records as new or old. The spatial distribution of these new corrosion points is evaluated under a null hypothesis of Complete Spatially Randomness (CSR) against the alternatives of clustered or dispersed distributions. Finally, the location of these new corrosion points is simulated using a non-homogeneous Poisson process. The possible interaction with old corrosion points is evaluated following a repulsion or attraction permutation test. This chapter aims to present the main results of this framework based on the measurements from both pipe walls and inspections.
