Arora ATLAS vs. Bently Nevada System 1 Asset Health Management Software

The software is well suited for capturing transient events and allowing for playback to use its diagnostic features to work through solutions. Many times during a startup on a large steam turbine, vibration events will come in that restrict the unit from coming online, so Operators need to know what is causing the issue and how they can work through it to get the unit online and producing power with little delay. Having Bently Nevada System 1 Assent Health Management Software online continuous monitoring allows me to access the data and troubleshoot without delay involved as in the past when I would have to travel to the site and setup monitoring gear then attempt to startup again and hope to capture the event.

• Capture transient data
• Provide email notification of alarms
• Intuitive setup and use of functions

• Due to the power of the software, there are many attributes that I'm not aware of, so a better guide for use would be helpful
• Better controls for reducing excessive alarms
• Need improved searchability of online Help

We considered Emerson AMS Machine Works and associated products for online rotating machinery monitoring, but the application was not as intuitive to use and would have required many hardware upgrades of field devices to measure vibration where most or our power plants already had existing Bently Nevada vibration monitors that could easily be linked to System 1.

• The savings involved with bringing a unit online without delay due to online condition monitoring
• The savings involved with online diagnostics and monitoring in keeping the unit running safely without damaging anything while planning for a convenient time to bring it down for repairs and knowing what parts and labor will be required due to diagnosing the problem ahead of time.
• The cost savings of reducing the need for labor to travel for diagnostics or periodic data collection using portable or handheld vibration analyzers
