The potential of predictive maintenance for critical port infrastructure, reducing risks and extending its life cycle, remains to be unlocked by suitable quantitative information that fosters predictive maintenance and sustained investments towards progressive climate-proofing of the infrastructure. The PI-BREAK (Predictive Intelligent system for BREAKwater maintenance) project apply state-of-the-art monitoring and modelling techniques to the maintenance of the Punta Lucero rubble mound breakwater in the port of Bilbao, Spain. Among the tasks performed in the project, 3D physical model tests have been performed at the directional wave tank named "TOD" from IHCantabria, to assess the breakwater performance and analyze risk levels with and without maintenance interventions. From the different configurations tested at the TOD basin, some will serve as a wave breaking benchmark to be shared with the scientific community.
