Alarm Management

Integrated alarm management tames nuisance alarms that can hamper your process and operations 

 

If your plant operators are plagued by nuisance alarms, they’re probably not operating your plant at peak performance. Nuisance alarms include those that annunciate excessively or unnecessarily, don’t return to normal after they’ve been correctly addressed, or are irrelevant to the current process state. These all serve to distract your operators from the primary task of optimally controlling your process. Prolonged exposure to nuisance alarms can desensitize operators to alarms in general—not a safe way to operate your facility. It’s not unusual for up to 80% of the alarms to come from nuisance sources—and those sources often number as few as a dozen.

 

Now, imagine a program that can identify and eliminate those ‘bad actor” alarms and significantly quiet the control room, freeing your operators and maintenance personnel from needless interruptions.

 

That’s what the integrated alarm management tools for the DeltaV Distributed Control System help do. They make it easier and less costly to achieve and sustain optimal alarm performance as recommended in EEMUA-191 Alarm Systems – A Guide to Design, Management and Procurement and ISA-18.2 – Management of Alarm Systems for the Process Industries.

 

Unlike general-purpose layered alarm management systems that require extra hardware and software to engineer and maintain, integrated DeltaV system alarm help and analytic software are ready for use from the moment they’re licensed.

 

DeltaV Alarm Help gives operators one-click access to reccommended actions, probable cause and other alarm guidance-- from the alarm banner, alarm list or faceplates. The results: quicker, more consistent operator response. DeltaV Alarm Help is easily tailored to accept information contained in existing alarm response manuals. It can also be deployed as a knowledge capture system where senior operators can add information for either immediate sharing or engineering review.

 

DeltaV Analyze provides continuous automated monitoring of alarms, events and user actions trends. Its intuitive point-and-click graphical interface empowers operators and other operations staff to investigate and identify nuisance alarms with no special training. Out of the box, DeltaV Analyze is ready to use without system interface design, webpage configuration or report creation. A built-in alarm statistics report provides Key Performance Indicators as prescribed by ISA-18.2 and EEMUA-191.

 

Emerson alliance partner product SILAlarm™ from exida LLC provides alarm rationalization— the process for qualifying and specifying alarm design criteria. SILAlarm supports the native DeltaV bulk edit system to easily bi-directionally transfer or compare alarm settings with the DeltaV system, including advanced alarm settings and alarm help information.
