This project aims to create a comprehensive framework to evaluate the potential benefits of mixing inspection and monitoring technologies for corrosion surveillance. Four key components are integrated: (1) corrosion progression modelling, (2) simulation of ultrasonic thickness measurements, (3) subsampling protocol design, and (4) statistical reliability analysis. By employing movable sensors that can be strategically repositioned in high-risk zones, this approach is shown to significantly improve detection reliability while requiring fewer sensors, reduced spatial coverage, and longer inspection intervals.
