The following scenario
is an example of how Emerson’s Machinery Health technologies
work together to provide turbine protection: You are
comfortably home for the evening when the phone rings and
you learn the turbine just tripped. The decision to restart
the equipment is yours. Although you feel the pressure,
you are confident because you have two powerful tools to
rely on–all the necessary data was captured to assess the
event and a live user interface will provide assurance during
start-up. Information before, during and after the turbine
trip is waiting for you. As you drive to the site, you review
the facts:
- You have the proper setup to capture the right data
surrounding the event. With virtually no setup, you
can be assured the right data and the anomalous event
will be captured.
- Real-time continuous data recording ensures events
will not be missed. With the CSI 4500, a 60 hour running
history is recorded all of the time. The CSI 4500’s
continuous data recorder will record and buffer from
60 hours to over one week, depending on the number of
sensor inputs. Auto archiving of data is also included
so that small, one hour, snapshots can be permanently and automatically saved to a network server.
- The live turbine dashboard will enable real-time decisions
during start up.
When you arrive on site, they have already found a plugged
oil line to the bearing. Now the question is “how much damage
was done, and can we restart?”
Multi-channel, continuous data recording saves you from
ever missing an event and ensures the right information
is available to dig deeper into the problem. You look at
the quick views and then extract the region of interest
for more details, which quickly drives you to the source
of the problem.
You can review the data, compare with the baseline, and
confirm the vibration is isolated to one bearing. The shaft
centerline plots tell you the bearing clearance was not
exceeded. After fixing the oil flow issue, you advise restarting the turbine as you watch the live turbine dashboard.
The live turbine dashboard provides real-time decision-making during start-up.
The live user interface, available with the CSI 4500
transient system, provides live plots that were not possible
before the GT2 processor. Live real-time plots such as overall
levels, orbits, shaft centerline, Bode/ Nyquist, cascade,
waveform and spectrum, on all bearings, allow a turbine
specialist to make real-time decisions. Simple Windows displays
make manipulating screens and plots easy. Dual monitor mode
helps you organize your views so you are staged for the
startup. You can overlay baseline plots (from portable or
online systems) on known good start-up plots to view the
differences.
With the transient live turbine dashboard, you can make real-time decisions with operators and production staff
to bring the turbine up for critical production needs or
to shut down again to save the asset.
In this scenario, the CSI 4500 along with the AMS
Machinery Manager allowed the user to easily see the information
to make a confident decision. Emerson’s predictive technologies,
such as the AMS Suite of applications and the CSI 4500 along
with complementary PlantWeb Services, allow you to maximize
availability and performance of key production assets to
ensure operational excellence.
