3. FMEA (25%)
Perform an FMECA study for the case of an offshore wind turbine according to the BS EN 60812 2006 standard. In the study all steps of the design, manufacturing, installation, operation and maintenance should be considered. A block diagram including the system/process break down should initiate the study, showing subassemblies, components and parts. For each part, the different failure modes should be marked separately. Students should consider identification and marking of fewer than 10 and no more than 20 failure modes, benchmarking their criticality based on their Risk Priority Number (RPN). Students are encouraged to review examples included in the lecture slides as well as appendix of the relevant standard in order to better understand the concept of executing an FMECA study.
4. Risk-based Maintenance Management (25%)
