How can we help makeyour turnaround more
efficient and effective?

As you prepare for turnaround season, Bently Nevada’s
experienced Services team can help you with the following:• Conduct a customized site survey.
• Generate a variety of detailed condition monitoring reports.
• Assess your machinery and other equipment assets.
• Provide specific turnaround activities.

Site survey

Site surveys are performed to verify suggested parts lists,
provide technical recommendations and monitoring systemfirmware review, which would be the first step to ensuring you
have a productive and effective turnaround encompassing
all your critical assets.
Spare parts assessment• Provides detailed overview of all recommended
spare parts.
• Helps ensure that required spares are available when youneed them with proper planning so that instrumentationand monitoring rack issues do not cause unnecessary
delays to the turnaround.
• Requires access to all transducers, junction boxes andmonitoring systems.
Technical recommendations• Offers detailed review of Bently Nevada Technical
Information Letters (TILs).
• Reports are issued for all necessary recommendations.
• Delivers notifications and information on all known issues.
• Provides clear description of any issues, plus advisory and/or technical recommendations on how to resolve.
• Appropriate TILs brought to attention of the customernominated authority to develop action plan.
Monitoring system firmware review• Review version of Bently Nevada system firmware andrecommendations on critical updates and featureenhancements.
• Maintains monitoring systems to latest versions of firmware.

Machinery health reports

Machinery health reports provide insight on the asset
condition during startup and normal operation after
the turnaround.
Machinery health report (pre-turnaround)• Performed while machine is running in steady state.
• Includes review of historical data.

• Identifies machinery and equipment/system malfunctions,eliminating surprises when machine is disassembled
during turnaround.
Machine shutdown report• Performed as the machine is shutting down.
• Includes detailed machinery shutdown data analysis.
• Transient data provides information that is difficult
to detect in steady state conditions, especially when
historical data is unavailable.
• Transient data is used to evaluate the static forces acting
on the shaft.
• Helps evaluate malfunctions like shaft cracks,misalignments and rubs, etc.
Machine startup report• Performed as machine is starting up.
• Offers real-time support and data evaluation
during startup.
• Identifies any machinery or equipment malfunctions.
• Includes recommendations about safe operation ofthe machine.
• Includes preliminary evaluation of turnaround quality.
• Rotating Machinery experts and Systems Engineers
available to assist during machine startup (either onsite
or remote).
• In-situ balancing of the unit as and when needed basis toavoid downtime of the assets.
Machine baseline report (post-turnaround)• Performed while machine is running at normal
operating speeds.
• Includes comparisons to pre-turnaround baseline data.
• Includes detailed analysis of rotor dynamic behavior.

• Provides detailed analysis of rotor dynamic behavior andincludes recommended actions for the turnaround.

• Includes comprehensive evaluation of current machineconditions, and insight into general machine health.

• Includes comprehensive evaluation of current
machine conditions, and provides insight into generalmachine health.

• Documents baseline condition for future audits.

2• Verifies turnaround work has achieved desired result andno underlying malfunctions exist.

Pre/post-turnaroundassessment services

Assessment services assist in planning the appropriate work
to be performed on each asset based on its condition. A
pre-turnaround assessment is normally scheduled three to
six months prior to the turnaround, allowing you adequate
time to evaluate the report’s recommendations without
jeopardizing schedules and deadlines. To evaluate theeffectiveness of the maintenance performed during theturnaround, it is also highly recommended to conduct a
post-turnaround assessment to document results. This is
generally performed during startup.

Field instrumentation
Ensuring Proximity Transducer System components compatibility.
Visual inspection of field instrumentation to verify physical integrity (wear,tear and scratches).
Calibration and linearity checks of vibration points to verify the integrity of theinstalled systems in the field.
Performing loop checks using proper and calibrated test equipment (TK-3eand Shaker Table).
Installation and gapping of proximity probes as per vendor best practices.
Zero-Adjustment of axial displacement probes in coordination with plantmechanical team.

3500 Systems (and other BN monitoring systems)

The turnaround assessment…

Audit Rack Configuration as per vendor best practices.

• Service reports with outage documentation, test results
and information

Collecting system events/alarms and information for analysis.

• Helps to identify necessary maintenance and avoid
unnecessary maintenance.

Upgrade the firmware of the monitor (if applicable).

• Focuses on actionable information – what to work on, why
to work on it, its relative priority, and root cause.
• Includes Rotor dynamic analysis (shaft/casing/foundation
vibration as appropriate and startup/shutdown
data analysis.
• Includes thermodynamic performance analysis (ifapplicable performance package is available).
• In-situ balancing of rotating machines.
• Can be custom-tailored to fit unique assets and situations.
• Includes comprehensive documentation of Bently Nevada
systems (monitoring & transducers along with PNs & SNs)
provided via Turnaround Assessment Service Report.

Perform self-test for all monitors to verify all are in healthy condition.

Testing system hardware for any faults and correct if any (rack modules,wiring connection in rack modules, and server connectivity to the system).
Grounding checking for all MMS cabinets (will perform the pre-power up
checks, grounding checks, and shield termination checks).
Take complete backup.

System 1
Fine tuning of System1 server for data collection sampling rates andresolutions.
Perform optimization of the historical database to ensure the availability ofquality data with enough storage time span.
Data synchronization between 3500 racks and System1.
Startup support (to verify all BN instruments are installed andfunction properly).
Mechanical health assessment of the assets.

Start-up support
Instrumentation startup support to ensure proper functionality of all Bently
Nevada systems.
Machinery Diagnostics Start-up support to check machinery healthconditions to provide unbiased recommendations.

System hardening services
System1 servers will undergo a series of hardening procedures to maintain asecure environment, protecting against cyber attacks or other threats. This
service will require a valid M&S agreement. The following activities shall be
performed by Seller:
Hardening of network switches within the VMS (vibration monitoring system)
network. Devices outside the VMS network are not part of Seller scope inthis proposal.
Hardening of System1 servers as per Seller’s recommended Best Practices incompliance to Buyer’s applicable standards.

Turnaround field services

Recommended activities in turnarounds consist of an
overall health check of your primary monitoring system toverify that is in optimum working condition, plus verification,removal, and re-installation (as needed) for all transducer
systems throughout the entire plant. The table below
provides a list of activities typically performed in turnaroundby our services team:Installation of Windows updates and security patches as approved by seller
for the platform software. Thereafter Bently Nevada will provide updated list ofapproved OS patches on monthly basis.
Supporting antivirus update service and scanning/rectification.
Supporting services for RBAC (role-based access control) applicable to all
Bently Nevada software.
Post hardening completion security baseline report.
