Collection and
The Race is On: A Timed Test of Route Collection Tools
Refinery in the USA
Will We Have What We Need?
A refinery in the USA obtained a CSI 2140 Machinery Health Analyzer
to assist in their route data collection. They tested the accuracy and
speed of the new triaxial device to assess how much time and effort
they could save versus their old single-axis data collector. They also
compared the amount of data they could collect.
Setting Up and Performing the Test
Among the equipment trains (including turbine and pump trains) they
chose for their test, some equipment had been performing reliably,
while some equipment had been experiencing occasional trouble.
“Those data show a huge time
savings and good cost justification.”
- Lead Test Engineer
The technicians benefited from the CSI 2140’s five inputs (four-channels and a tachometer) because
they could measure horizontal, vertical, axial, and early bearing detection (PeakVue™ measurement)
simultaneously while gathering tach data. A triaxial sensor assists in this situation because it creates
the illusion of working with only one sensor, but provides the same data as three sensors.
During the tests, the technicians hit enter once and obtained four readings — simultaneously.
Whereas traditionally with a single-axis accelerometer they were measuring only one channel at
a time and had to move the sensor multiple times.
Faster, More Comprehensive Data Collection
The testers were shocked at the ease of measurement and the difference in collection times. For
their test, the technicians measured collection times from the moment they pressed “start” to the
moment the data stabilized.
•On a single machine, the single-axis collection time was 6.3 seconds; the triax was 2.3 seconds.
•For an equipment train, the times were: single-axis collection (included 12 points) 1 minute,
49 seconds; triaxial (adding a PeakVue point to each bearing in the train for a total of 16 points)
29 seconds.
The testers were pleased with the CSI 2140 data accuracy as well as the ease of performing
complicated tests. Because a tachometer is part of the data collection options, all data has the
same time stamp. This simplifies tests such as seeing machinery movement relative to two sides
of a machine train: the pump and the motor. No special activity is required to gather that type of
information; it is part of the automatic data collection.
Collection and
A Matter of Time in Route Data Collection
Power Plant in the USA
How Can Data Collection Time Be Reduced?
The predictive maintenance team at a large power plant in the USA had
to monitor a complex variety of equipment–conveyors, gear boxes,
pumps, turbines, blowers, compressors, pulverizers, fans, and mills.
With all this machinery, they had a difficult time completing their
route-based data collection. They wanted to complete the collection
in less time and with greater accuracy.
Simultaneous Measurements, Plus a Tach
Typically, route-based data collection requires the user to place a sensor multiple times for each
machine bearing; one sensor measurement for each of the three axes. It’s a daunting task when
faced with testing hundreds—or thousands—of machines.
The customer decided to test the capabilities of simultaneous four-channel data collection via
the CSI 2140 Machinery Health Analyzer. Used in their route-based data collection, the CSI 2140
offered four-channel monitoring and a triaxial accelerometer measurements simultaneously so
that one measurement action collected data for all three axes. They measured multiple bearings
simultaneously—significantly streamlining advanced diagnostics, such as Operating Deflection
Shape (ODS) analysis.
They found that not only was the testing itself more efficient with three simultaneous measurements,
but the processing speed of the device was 30% faster than the CSI 2130 (one of the fastest data
collectors in the industry) when collecting a measurement point.
They Found Time
The reliability team now completes their route data collection and analysis in 30 to 50 percent less
time. They cover more machines during their shift, and they can spend time analyzing data to better
focus on high-value tasks.
In addition, the team likes the convenience of the CSI 2140’s long battery life and the ability to see
the screen in low-light conditions without having to manually adjust the screen brightness.
Collection and
Vibration Analysis Tools Provide Insight during Collection
Refinery in Germany
Where Can Helpful Data Be Found?
After data is collected, it must be analyzed. What if a technician knew
which data would prove valuable for later deeper analysis? He could
gather that data while still in the field rather than making another
trip. A technician who had a rich set of analysis tools embedded in the
portable collection device could give potential answers to issues and
could provide direction for additional detailed data collection.
Field Analysis Helps Focus Data Collection
Recently at a customer site, an Emerson engineer used the analysis tools available in the CSI 2140
Machinery Health Analyzer to help prepare machines for start-up. After initially gathering data, the
engineer viewed the vibration spectrum for a few moments of the test. He found (as expected) the
running speed frequency of the machine. He also found (quite unexpectedly) a ghost frequency.
In the field without leaving the machine, the engineer—by simultaneously viewing dual-orbit plots
available on the CSI 2140—looked for instabilities or other conditions that could lead to machinery
damage. He then gathered additional data required for further analysis using AMS Suite tools in the
control room. In fact, if required, the engineer could have chosen from 14 additional diagnostic tests
to assist in deeper analysis in the field.
Data, Ease, and Insight
The CSI 2140 simplified and streamlined test configuration, field measurements, and plot analysis.
In fact, if it were not for the ease of data gathering and analysis, some testing and analysis completed
in this study might have been skipped due to the time they would have required.
•Ease of measurements—Without the ease of use and four-channel capability of the CSI 2140, time
might have been spent measuring rather than designing additional tests and analysis to determine
the source of the ghost frequency.
•Depth of data—Some of the analysis would not have been possible without the tach pulse input that
was simultaneously gathered with data from the four sensor inputs.
•Rich analysis tools—The side-by-side plotting and the ability to select the points for further analysis
made the CSI 2140 an invaluable tool in assessing the risk of the vibration.
Predicting Gearbox Failures with
PeakVue™ and Wireless Monitoring
SABIC Petrochemicals in the UK
How Can You Be Sure You Won’t Miss a Problem?
Not long ago at SABIC UK Petrochemicals, vibration data collection
and analysis for their olefins cracker pumps were performed
manually. Between the manual readings, however, potential problems
sometimes arose that led to higher maintenance costs and reduced
plant availability.
“Wireless monitoring has shown itself
to be a valuable tool in our condition
monitoring armory. Predicting
failures in gearboxes of this type can
make considerable savings on any
subsequent turnaround and help to
keep equipment available.”
- David Hambling, Instrument Electrical Technical Engineer
Simply put, SABIC “wanted to improve the monitoring of critical
pumps at the Olefins plant in Teesside,” according to David Hambling,
SABIC instrument electrical technical engineer.
Continuous Monitoring in an Easily Created
Wireless Network
The SABIC olefins team chose to install a wireless condition monitoring
and prediction system that included the CSI 9420 Wireless Vibration
Transmitter and PeakVue technology.
Since the plant already had an Emerson Smart Wireless network, the
installation of the wireless vibration transmitters was simple, and the devices started broadcasting
machinery health alerts based on the vibration readings to the distributed control system almost
immediately. In the future, the established mesh network will simplify adding or relocating wirelessenabled devices for additional process information from remote or difficult-to-access locations.
At the site, the CSI 9420 measured overall vibration and temperature, while PeakVue technology
detected faults that could cause friction, impacting, and fatigue—particularly in gearbox and rolling
element bearings. The monitoring system reported machinery health alerts every 30 minutes and
conducted an in-depth, full-spectrum analysis once every day.
Detection before Failure
Since installation, Emerson’s online vibration monitoring system has detected a number of problems
that could have resulted in equipment failure, including a chipped tooth on a gearbox gear and an
impending bearing failure.
Identifying and rectifying potential problems earlier has helped minimize pump failures and
maintenance costs and has improved maintenance scheduling. It also has helped reduce the risk of
unexpected failures that can result in lost production as well as safety and environmental incidents.
Improving Safety and Reliability with Wireless Vibration Monitoring
Flint Hills Resources, Refinery in the USA
How Can You Prevent the “Bad Day”?
A Flint Hills Resources (FHR) plant in the USA—processing 320,000
barrels per day of high-sulfur heavy crude—performed a process
hazard analysis (PHA) that showed 110 high-risk pumps were
potentially subject to vapor cloud release and explosion.
FHR was looking for a reliable, cost-effective way to prevent that “bad
day.” They needed an early detection method to determine when
they were operating in a high-risk mode so that they could avoid
pump failure. With this early detection, FHR hoped to manage the
risk of pump failure, avoid injury, process shutdown, and additional
maintenance expense.
One effective method to obtain early warning is about developing pump
defects is vibration monitoring using Emerson’s PeakVue technology.
“With just one such situation,
Flint Hills had achieved its
objectives with the data.”
- Nick Jude, Rotating Equipment Reliability Engineer
Vibration Data Collection and Analysis Brings Results
FHR chose the CSI 9420 Wireless Vibration Transmitter for early detection of hazardous vibration and
impacting. The rugged CSI 9420 connected quickly to the pumps to deliver vibration information
over a highly-reliable, self-organizing WirelessHART® network.
FHR identified Emerson’s PeakVue measurement as the best indicator for high-risk operating states
on their pumps in hazardous service. PeakVue detects the impacting caused by rolling element
bearing faults, under lubrication, and pump cavitation—all major causes of pump failure if left
unaddressed. The data is reported to the control room. When the PeakVue readings cross a predetermined alert level, the facility has a procedure to address the issue within a certain timeframe.
The on-site maintenance engineer can also tap into the vibration measurements provided by the
CSI 9420 to perform advanced diagnostics and troubleshooting.
Discovery and Resolution of Vibration Issues
Having the data provided by Emerson’s CSI 9420 wireless vibration transmitters, Flint Hills now
knows which pumps need to shut down and which pumps could safely remain in operation. In fact,
in the first eight months of the new detection scheme, FHR found and addressed three or four
potentially hazardous situations.
Ensuring Safe Operation of Remote Assets
and Wireless Monitoring
Large Refinery in India
How Do You Monitor a Cooling Tower?
The maintenance team at a large refinery in India struggled
with this exact question. Although breakdowns lead to serious
process disruptions, it seemed there was no good solution. Monitoring
the vibration with portable equipment was too hazardous, but
online vibration monitoring was too expensive. Installing vibration
switches looked like a promising solution, but ultimately proved
ineffective because the switches failed without notice, leaving
these key assets completely unprotected.
Around the world customers experience difficulty in monitoring their cooling systems because they
are in remote, hazardous, and unpleasant locations.
Here’s the catch: For many plants, losing cooling ability leads to a costly process slow down or even
shut down.
Wireless Transmitters Reduce Cost
This refinery found their solution in the CSI 9240 Wireless Vibration Transmitter, and they discovered
that—with Emerson’s solution—vibration monitoring of the gears and gearbox bearings could be
installed at a relatively low cost.
As part of an Emerson highly-reliable, self-organizing wireless Smart network, the CSI 9420
connected easily and economically to a wide variety of machines. It delivered vibration information
for use by operations and maintenance personnel.
In addition, configuration, diagnostics, and alerts could be imported into AMS Suite: Intelligent Device
Manager software for deeper analysis and greater improvements to the maintenance process.
Data Automatic and Complete
This refinery now has the reliable monitoring that it needs. Changes in gearbox vibration are visible to
the operators in the control room and stored in the plant data historian. Furthermore, the maintenance
and reliability team receive detailed diagnostic data automatically in AMS Suite: Machinery Health
Manager software for full vibration analysis.
The CSI 9420 provides constant updates about the asset condition to the control room so that they
can avoid surprises and schedule repair activity in advance of a failure.
SIL3-Certified Overspeed Protection for Hydro Turbines
Hydropower Plants in Brazil
Replacing Mixed, Inefficient Technologies
As a Brazilian company began to modernize the controls of multiple
hydropower plants and a dispatch center, the power producer’s goals
included helping to boost unit reliability, flexibility, and efficiency. Because
their facilities used outdated controls based on proprietary technology
from many vendors, the company had a difficult time finding parts and
integrating the controls with other equipment and devices.
Move to Unity
The customer chose a unified solution that included Emerson’s Ovation™ control, SCADA technology,
and CSI 6300 SIS SIL3-certified digital overspeed protection system for their hydro turbines. In addition,
they opted for AMS Suite to equip maintenance and operations staff with valuable insight into asset
health — thus minimizing downtime and unplanned outages.
Turbine Protection Leads to Improved Plant Performance
At these sites, Emerson’s Ovation control system is the first distributed control system in Brazil to control
the turbine and balance-of-plant equipment and processes, including wicket gates and the cooling
system. Because it now controls plant processes and regulates turbine speed, the Ovation system helps
ensure precise frequency control and smooth synchronization to the grid.
In addition, the overspeed protection system currently helps the customer in these ways:
•During transient operations like start up, shut down, and load change, the CSI 6300 SIS guards against
overspeed conditions caused by sudden load losses and verifies the rotational direction to ensure your
assets function correctly.
•During normal operation, the CSI 6300 SIS protects equipment from going into an overspeed condition
caused by unexpected changes and sudden load losses.
•The customer’s system has a SIL2-rated rotational direction detection so that the rotational direction
of the machine is detected immediately when it starts.
•With Advanced Gap Drift Warning, the system constantly checks the position of its sensors. If the
mechanical distance changes due to what reason ever, the system gives the customer early warning,
•The overspeed protection system always works with the optimal trigger level, independently from
changes in the sensor-target position.
By replacing obsolete controls with a common automation platform and overspeed protection, these
hydropower plants have gained methods to improve overall control, plant performance, and reliability.
Protection and
Integrating the DCS and Machinery Protection
Power Generation Plant in the Middle East
A Search for Integrated Turbine Protection System
One of the largest power generation companies in the Middle East
recently embarked on a broad automation system upgrade at one of its
main power plants. An integral part of the initiative included the upgrade
of its existing turbine protection system to meet current safety and risk
mitigation standards.
Easy Integration
Emerson’s overall solution included building on to an existing, installed Ovation
distributed control system platform. The customer chose the CSI 6500 for its easy
integration to Ovation and its protection capabilities.
The easy three-step integration between the CSI 6500 machinery protection system
and the Ovation system promised to save the power generation site hundreds of workhours and provide complete, error-free integration of machinery information with the
Ovation system.
The customer also recognized the opportunity for real-time integration of machinery
information into the Ovation system. The complete system would deliver actionable
information to operations staff and protect the condition of critical machinery assets.
One Company, Complete Solution
Emerson’s monitoring expertise and world class Ovation turbine control system
delivered a complete control/protection solution that was founded on one source for
control, protection monitoring, and sensors.
The integration of protection data into the control system now pushes key protection
parameter data faceplates onto Ovation operator displays within just minutes of system
setup. It daily enables operators to have continuous real-time access to critical turbine
and generator vibration and position status — it was made possible through out-of-thebox Ovation HMI macros.
Protection and
Moving to Online Monitoring Improves the Bottom-Line
Anadarko in the USA
Expensive Failures Even with Monthly Route-Based
Anadarko, a significant processer of gases from oil wells, contracted
vibration reliability services to check equipment including critical
reciprocating gas compressors each month. But many failures
occurred so quickly that the once-per-month checks proved to be
inadequate. Each reciprocating compressor failure resulted in more
than $12,000 per hour in lost production.
Anadarko needed a comprehensive online monitoring solution
that provided visibility to failures of roller element bearings and reciprocating
compressor valves. Anadarko required remote monitoring of reciprocating
compressors for real-time access to catch problems that develop quickly.
Continuous Monitoring Predicts Failures
Well equipped with two 48-channel CSI 6500 transient units including PeakVue
and Modbus to monitor two critical reciprocating compressors, Anadarko’s
solution also used AMS Machinery Manager software and remote-monitoring
AMS Asset Performance Manager software.
Anadarko recognized that by using the CSI 6500 to help them monitor machinery
health, they would no longer run blind. In addition, they understood that the
PeakVue technique would provide a simple, reliable indication of valve health
viewable via a single trend.
Prediction Leads to Correction and Profits
Anadarko’s choice proved to be a win for them. They now have detailed diagnostic
data at their fingertips wherever they have an internet connection. Now they can
monitor machines, predict issues, and correct issues before they lead to bottomline losses.
Protection and
Operators Obtain Visibility to Critical Machine Issues
Ethylene Oxide Facility in Mexico
Replacing an Outdated Maintenance Process
An ethylene oxide facility in Central Mexico had been working with
online machinery protection systems, but they needed a more modern
system to perform both online prediction and protection. In addition,
they had been performing route-based collection maintenance by
using hand-held portables. They realized an updated solution could
include both protection and prediction, eliminate the walk-around
measurements, and include prediction on additional machines.
Including Protection and Prediction
The company selected Emerson in part due to the transient capability of the
CSI 6500. They realized that by using the CSI 6500 with the transient analysis
option, no data would be missed. Any questions about machinery health could be
answered with continuous data and playback capability.
Housed in a single chassis, the CSI 6500 provided the customer proven prediction
and protection to provide a complete online machinery monitoring solution.
The Solution
The customer site is now monitoring three oxygen compressors and three air turbo
compressors. They are monitoring radial, axial, temperature, speed, and phase for
each machine. In addition, all data are integrated to the distributed control system
so the operators can monitor the plant’s most critical rotating machines. Overall,
the facility gains real-time machinery health feedback integrated with process
automation and can transform vibration monitoring into predictive alerts.
Protection and
Prediction-Based Maintenance Improves
Offshore Maintenance
Norske Shell Draugen, Oil and Gas Platform
in the North Sea
Can Poor Spare-Parts Supply Produce Better
Yes … if the situation leads to a change in supplier and an improved
strategy to increase predictive maintenance. Shell had supply
and support problems that, in part, drove them to rethink their
machinery-health program.
Shell’s goal: Use predictive maintenance in 40% of maintenance
workload — helping improve maintenance efficiency and increasing production. Shell’s plan: Migrate
to a system that takes advantage of current prediction and protection technologies from Emerson’s
Reliability Solutions group.
Prevent Key Assets from Failing Unexpectedly
For years, Shell embraced both protection and machinery health management systems. It was
not enough. By updating technology and adding prediction capabilities, they found enhanced power.
Now in place at Shell, Emerson’s prediction-and-protection system records up to 100 hours from all
channels and saves the data to a hard disk. By reviewing the information after an event, personnel gain
a greater understanding of the cause and can devise the proper fix.
The prediction solution from Emerson is a powerful step beyond protection. For example, Shell
installed new seals on a gas compressor during a planned shutdown. But after the change, they noticed
compressor instability. The monitoring system provided a predictive parameter to Shell which enabled
them to discover and address an imbalance near the center of the shaft.
In addition to using protection and prediction capabilities, Shell now integrates data from remote online
machinery health monitoring systems. Shell personnel efficiently review data, compare data from other
offshore platforms, and determine best-practice solutions for potential problems.
An Ambitious and Attainable Plan Delivers Results
Specific results are visible. For example, Shell personnel evaluated data from the gas compressor and
determined how to address an imbalance: they scheduled an overhaul and balance check/correction
during a short shutdown. This saved approximately one and a half days of compressor downtime —
saving about 60,000 barrels of oil. Since then, the compressor has been stable and shows lower vibration
levels, which reduces stresses on the equipment and extends time between maintenance.
Monitor equipment accurately. Identify potential problems early. Prevent assets from failing
unexpectedly. Your result: Increased production and improved maintenance efficiency.
Protection and
Needed: Confidence in Production
Copper Production in Chile
Equipment Reliability Affecting Production Goals
A large copper producer in Chile, producing over 350 million tons
copper/year, was under intense pressure to increase their equipment’s
availability to ensure production goals. They recognized they had to
invest in high-quality online prediction and diagnostic technology to
assure they could address critical machinery issues before potential
unforeseen shutdowns occurred.
Data and Recommendations Easily Understood
The customer chose to include in the solution six CSI 6500s with prediction
capabilities on multiple crushers, agglomerators, and refining pumps. The
transient feature of the CSI 6500 was included in the solution to be able to replay
the conditions as necessary for analysis.
PeakVue also was chosen as part of the solution so that the engineers at the mining
facility could interpret easily machinery conditions and could determine both
when a machine fault exists as well as the severity of the defect. PeakVue was also
chosen because it could provide diagnostic information that assists in determining
the exact nature of the defect and recommended targeted remediation.
Business Results
This is the first of multiple investments already planned for additional
critical equipment.
Cutting Through the Complexity of Machinery Analysis
New Technology
Traditionally, vibration data has not been routed to the control room
because it required specialized training–and frequently specialized
tools–to extract any information from the data.
Emerson’s PeakVue technology cuts through the complexity
of machinery analysis to provide a simple, reliable indication of
equipment health via a single trend. PeakVue filters out traditional
vibration signals to focus exclusively on impacting, a much better
indicator of overall asset health on pumps, fans, motors or any other
type of rolling element bearing machine.
Simple Interpretation
As a measure of impacting, PeakVue readings are much easier to
interpret. A good machine, properly installed and well lubricated,
should normally not have any impacting on it. This establishes the
zero principle:
The PeakVue trend provides operators
with a simple yet conclusive way
to verify when a machine is in good
condition and provides early warning
of developing problems with an
indication of severity.
The PeakVue measurement on a good machine should be at or close to zero.
As common machinery faults begin to appear on rotating equipment (e.g. rolling element bearing defects,
gear defects, insufficient lubrication, or pump cavitation), the PeakVue reading typically can be evaluated
using the Rule of 10’s:
Rule of 10’s
PeakVue Reading (g’s)
Critical abnormal situation (Implement action plan)
Serious abnormal situation (Develop action plan)
Abnormal situation developing (Monitor more closely)
Bringing Reliability to the Control Room
With these simple principles, PeakVue is a powerful tool to bring reliability to the control room. Operators
with no special training in machinery diagnostics can use PeakVue measurements quickly and easily to
determine both when a piece of rotating equipment is healthy and when an abnormal situation is present.
Conclusive Analysis
Once an abnormal situation has been identified using the PeakVue overall, detailed diagnostic
information can be extracted from the PeakVue waveform or spectrum to determine the exact nature
of the defect. PeakVue can visualize distress signals on a machine that are simply not visible with other
vibration measurements. Earlier indication of developing defects facilitates optimum maintenance
planning and minimizes the impact on production.
Improving Dialogue between Operations and Maintenance
Power Plant in the USA
Frequent Failures
A power plant had been experiencing continued problems on an
atomizer, with frequent bearing failures about every three months.
Operations Makes the Call Based on PeakVue
The PeakVue trend makes it possible
for operators to discern machine health
without any specialized training.
The power plant installed an Emerson transmitter on the atomizer and
included PeakVue technology. At the point of start-up indicated in the
graph (area 1), the overall vibration readings (indicated by green line)
were all below acceptable levels. In contrast, the PeakVue readings
on one bearing (blue line) were already ranging from 30 to 40 g’s—
indicating that a critical bearing fault was likely already in play.
Six hours later, around midnight, the vibration at this bearing location (area 2 of graph) shifted
dramatically. The PeakVue levels rose sharply to above 100 g’s, while the overall vibration level
jumped suddenly from baseline to nearly ten times the fail-alert level. Both of these changes
indicated that the bearing was in the process of failing. The control room communicated with
maintenance planning to schedule maintenance for the following morning and continued to
monitor the machine closely.
By about 9 am, the overall vibration level (area 3 of graph) on an adjacent bearing suddenly
increased sharply from baseline level to about ten times the fail-alert level. At this point,
operations made an immediate call to shut down the process.
Operations Makes another Call Based on PeakVue
The defective bearing was replaced, and the machine was scheduled for start-up the following morning
(area 4). The operator, familiar with PeakVue’s Zero Principle, noted that the machine was running at
nearly 10 g’s at start-up. He contacted maintenance and asked them to check out the machine. As
result of the PeakVue warning and the operator’s prompting, the maintenance team discovered the
root cause of the repeated failures on this machine: the grease fitting was clogged. As a result, when
they lubricated the bearing, only a fraction of the grease actually made it to the bearing.
The maintenance team cleaned the grease fitting, reapplied lubrication, and as expected, the PeakVue
readings dropped below 1 g (area 5). The same asset that had previously failed every three months for
more than a year has now been running for more than two years without incident.
This step change in reliability was made possible by the ability of the control room to view and interpret
the machine condition and then function as an extra set of “eyes” for the maintenance group.
