StingRAY Failure Mode, Effects and Criticality Analysis: WEC Risk Registers


Analysis method to systematically identify all potential failure modes and their effects on the Stingray WEC system. This analysis is incorporated early in the development cycle such that the mitigation of the identified failure modes can be achieved cost effectively and efficiently. The FMECA can begin once there is enough detail to functions and failure modes of a given system, and its interfaces with other systems. The FMECA occurs coincidently with the design process and is an iterative process which allows for design changes to overcome deficiencies in the analysis. Risk Registers for major subsystems were completed in compliance with the DOE Risk Management Framework developed by NREL (document included below).
