The 54th ESReDA seminar on Risk, Reliability and Safety of Energy Systems in Coastal and Marine Environments will be held in Nantes (France) on the 25th – 26th April 2018, hosted by Université de Nantes (Nantes, France), IN COLLABORATION WITH WEAMEC.
In the field of Marine Renawable Energy, there are many technical issues and human challenges where risk, reliability and safety are involved: evaluation of uncertain resources (wind, wave, currents), material reliability, complex system reliability, electrical grid optimization, collision with ships, governance of risk in a multiusage area (fishing, tourism, maritime transport, European defense).
the 54th ESReDA seminar
The aim of the 54th ESReDA seminar is to bring together scientists, engineers and decision makers in the field of complex engineering system safety, structural health monitoring, cost/benefit assessment and risk management, in order to present and discuss innovative methodologies and practical applications related to complex system reliability, economical risk and human risk in complex environment. Scientific methodologies, theoretical issues and practical case studies are expected to cover all the range from academic to industrial applications, including electromechanical and civil engineering.
Topics include (but are not limited to):
- Reliability-based design and optimization (including structural, material and electromechanical issues);
- Service lifetime extension;
- Risks during sea operations and during service lifetime in a multi-usage area;
- Robustess quantification of complex systems;
- Electrical grid optimization and asset management;
- Life-cycle assessment and optimization;
