FMEA and FMECA

Arriscar offers FMEA and FMECA workshop leaders so that clients can assess risks associated with failures of systems, sub-systems or components, and develop prevention or mitigation measures.

Failure Mode and Effects Analysis (FMEA) is a methodology designed to identify the modes by which a process, equipment or component may potentially fail, to assess the effects (consequences) associated with those failure modes, and to identify and carry out corrective actions. FMECA is an extension of FMEA whereby both the consequences and likelihood of failures are assessed and the criticality of the failure assessed in terms of risk.

The technique is specifically useful for non-flow processes that are not well handled by HAZOP, for machinery systems, man-machine interfaces, electrical and electronic systems and components. Effects of human errors on systems are also covered. The methodology is largely based on IEC 60812.

The study facilitation covers stand-alone operations or to generate input to Safety Integrity Level (SIL) verification studies, Reliability, Availability and Maintainability (RAM) analysis and for Reliability Centred Maintenance (RCM) development.
