WP3 - Reliability approaches for decision-making
The Work Package Reliability approaches for decision-making (WP3) has the objective to apply the theoretical basis for reliability analysis and risk-based optimal decision making for life-cycle analysis to concrete foundations and towers for wind turbines along with bridge elements. For formulation of the stochastic modelling the JCSS Probabilistic Model Code1 will be used as basis. Further, fatigue mitigation of the structures will be considered. Methods for coupling monitoring information (throughout the life of the systems) with structural reliability models will be developed, in order to establish cost-efficient and safe maintenance planning. These methods will be based on Bayesian statistics and optimization of maintenance scenarios.
The Work Package leader is Prof. John Dalsgaard Sørensen from AAU.
4 ESRs are involved in 4 different PhD projects:
- Optimal maintenance planning of existing structures using monitoring data (ESR10 at PHIMECA)
- Development of methods for risk assessment of wind turbine support structures and bridges (ESR11 at AAU)
- Quantification of the value of monitoring information (ESR12 at BAM)
