FMEA Method. Risk Assessment During Metrological Expertise

Abstract

The purpose of the study is to identify and assess the risks of the metrological expertise of technical documentation in order to improve the effectiveness of the metrological support process and eliminate the possibility of risk events (such as failure of measuring instruments, inaccurate measurements using unapproved measuring instruments, etc.) during the design, installation, and use of gas supply systems.

Methods. In order to timely prevent adverse events, a risk-based approach is used, which is based on risk assessment methodology and focuses on preventive analysis. The most universal method of risk assessment is the FMEA (Potential Failure Mode and Effects Analysis) method.

Results. The risks of the process of metrological examination of technical documentation were identified using the example of organizations specializing in metrological activities in terms of conducting metrological examination of design documentation for gas supply systems. The application of the FMEA analysis method allowed for the categorization of risks based on their criticality using the Risk Priority Number (RPN) values. For risks in the critical zone, compensatory measures are proposed related to a specific examination process, which contribute to bringing all risk events to the area of low and moderate risk. Matrices are formed and filled in depending on the values of the probability of detection before and after the implementation of the recommendations.

Conclusion. A proactive approach to managing the risks of the metrological examination process. The proposed approach will improve the ME process and reduce the risks of repeated errors in the design of new technical documentation.
