Failure Mode Effects and Criticality Risk Analysis Review: Application within the Scope of the Wind Turbine

Failure mode effects and criticality analysis (FMECA) is an important probabilistic reliability model and an appropriate tool for future failures problem-solving. MIL-STD-1629A is one of the most popular FMECA standards from the U.S. Department of Defense. The following paper presents the results a Risk Priority Numbers (RPN) conducted for wind turbine assembly. This methodology is performed on the functional modes of the wind turbine components to perceive its performance, and determine its critical failures. The ranking of the failure modes criticality is realized based on the data collected from experts and decision-makers working in the renewable energy production area in Morocco. Further, the findings demonstrate that the generator and power electrical system are the two most critical components in the wind turbine system. Furthermore, the adopted methodology will help the decision-makers to improve the design of the critical components that require more attention and at the same time eliminate the inherent risks and deliver a system that respects the production standards.
