Maintenance Optimization for Critical Equipments in process industries based on FMECA Method

-In present era of automation and modernization, setting up of production plants involves huge capital investment especially for the process industry. The deterioration and failure of these systems might incur high costs due to production losses and delays, unplanned intervention on the system and safety hazards .The causes of failure may be human error, poor maintenance, inadequate testing, inspection or improper use and the resulting effects vary from minor in convenience to lost service time and sometimes to loss of material, equipment’s and even life. Several techniques have been used to determine the causes for the failure modes and what could be done to eliminate or reduce the chance of failure. The most notable methodology dealing with this issue is the Failure modes, effects and critique analysis (FMECA). Failure modes, effects and critique analysis (FMECA) is an integral part of the technical design of maintenance and it represents a strong tool to evaluate and improve system reliability and therefore reduces costs associated with maintenance that is used in a wide range of industry. This allows to optimize the components while identifying the most critical elements and helping decision makers to define maintenance service with appropriate maintenance policy.
