Publication year 2016 Abstract The reliability and availability of the Dutch storm surge barriers are calculated by probabilistic risk assessment and various underlying risk analysis methods. These calculations, however, focus on the numerical probability of the storm surge barrier functioning adequately, and the implementation of the many constraints from the risk analysis is merely an implicit factor. This includes constraints varying between whether the set repair times are feasible and whether the organization is capable of managing the asset adequately. Thus, the resulting reliability and availability figures should be validated, verifying the checks and balances on the behavior of the asset manager in terms of the performance of the maintenance and operational processes, but also the quality and knowledgeability of the maintenance and operational teams, among other checkpoints. In other words, the conformability of the organization should be verified during the performance assessment, in order to validate the risk analysis. Within Rijkswaterstaat, and for specific use at the storm surge barriers, a tool has been developed for an internal audit on the resilience of both the organization and the constraints following from the risk analysis – the compass. This paper focusses on the approach Rijkswaterstaat has chosen for the review of the validity of a risk analysis, including the adaptation of ISO and auditing standards, specific check points on risk analysis matters and the self-auditing regime that Rijkswaterstaat proposes for the storm surge barriers and their performance analysis Subject Fluid & Solid MechanicsSR - Structural ReliabilityTS - Technical SciencesBuildings and InfrastructuresArchitecture and Building2015 UrbanisationSelf-auditing toolRisk-based asset managementStorm surge barriersPerformance assessmentValidation of risk analyses To reference this document use: http://resolver.tudelft.nl/uuid:e0b23353-2cf0-4f4a-b27e-5648f4eec331 TNO identifier 567427 Source The 49th ESReDA Seminar: Innovation through Human Factors in Risk Assessment and Maintenance.
