Methodologies d’évaluation de la sûreté des structures vieillissantes - Panorama et benchmarking

Abstract : The assessment of the safety of aging structures is mandatory to ensure appropriate operations of industrial systems. The needs of coherent and adapted methodology become more and more significant in various engineering fields, knowing the large number of equipment and their actual ages, on one hand, and the limitations of re-investment capacity, on the other hand. The project IMdR P10-2: “Methodologies of safety assessment of aging structures – panorama and benchmarking”, to which seven subscribers have participated: AMETHYSTE, BUTAGAZ, CETIM, EDF, INERIS, RTE and SNCF, has as an object to identify the existing scientific methodologies, which are applied in different industrial fields, in order to highlight the main concepts, and the requirements in terms of data and skills. For each family, the level of uncertainty control and the risk consideration are identified. A benchmark composed of three industrial examples (atmospheric tank, pressurized pipe and steel structure), based on real data, is established for comparison of the different methodologies, in terms of data acquisition, uncertainty analysis and risk consideration in managing and monitoring the state of the structures.
