Honeywell Introduces SIS Health Monitoring System

Honeywell Process Solutions has introduced what it says is a unique set of technology and services designed to help industrial professionals monitor the health and reliability of safety instrumented systems (SIS). By precisely monitoring system status, Honeywell SIS-Health Monitoring reduces unnecessary maintenance and engineering of these systems and minimizes failures, which can lead to safety incidents and unexpected plant downtime.

Reports suggest that more than 20 percent of plant incidents are caused by SIS maintenance and testing errors. Often, SIS maintenance and testing are performed too frequently because system status cannot be accurately monitored. This unnecessary maintenance opens the door to human errors that can cause the system to fail. Additionally, the lack of reliability data has lead to unnecessary engineering of SIS, which can also lead to system failure.

Honeywell’s SIS-Health Monitoring is a toolset that can be customized for specific plant requirements, conditions and process demands. The current release includes two modules that can operate as standalone units or together as an integrated system:

The SIS-Health Monitoring Local Reliability Database, which can be applied to any SIS and stores all inventory information regarding a site’s safety instrumentation. Based on the failure behavior of the site’s instrumentation, SIS-Health Monitoring can help determine reliability and safety performance characteristics such as trends, demand rates and time-dependent failure rates.

The SIS-Health Monitoring Analysis Toolset, which enables operators to analyze, validate and optimize the SIF reliability and its Safety Integrity Level (SIL), which is a statistical representation of reliability.
