Fuzzy logic-based safety design for high performance air compressors

This paper presents problem of silted water causing equipment degradation. It proposes a safety design including instrumented and non-instrumented systems to resolve this issue by specifying safety life cycle activities including risk analysis, risk reduction, safety system requirements, safety system implementation and safety assurance. It uses case study as an example and proposes implementation of pressure transmitter linked with fuzzy logic to proactively take actions and report equipment condition to plant personnel. Analysis concluded that safety instrumented system (SIS) proposed will reduce maintenance burden, save resources, and improve system reliability by detecting failures proactively with better risk reduction factor (RRF). It is recommended that this SIS be implemented at all Nuclear Plants facing equipment problems related to silted water.ObjectiveTo investigate problem of silted water causing equipment degradation using safety instrument system and provide pathforward.
