Abstract: This paper focuses on failure analysis using two techniques developed from Failure Mode and Effect Analysis (FMEA), one of the most used methodologies to determine causes and consequences of failures: Failure Mode, Effect and Criticality Analysis (FMECA) and Failure Modes, Mechanisms and Effect Analysis (FMMEA). In this paper their combination is shown to optimize the benefits of both and overcome their drawbacks. This approach ensures high efficiency throughout equipment design and guarantees suitable maintenance policies. It has been applied in a redundant architecture based on temperature sensors included in a Safety Instrumented System for Oil&Gas application.
