Tango™ Condition Management
The objective on Tango's Condition Management function is to facilitate the "Elimination of Failures in Service."
In Service Failures on Critical Plant Equipment can be eliminated by the rigorous
application of condition monitoring (PdM), physical inspections and special testing
of plant equipment. This approach is often called Condition Based Maintenance. Tango™
provides a systematic approach that allows you to achieve integration, communications,
accountability and performance metrics in your condition based maintenance program.

Often it is difficult for a plant to consistently move from condition data that
indicates a machinery problem to successful, timely repair of the equipment. Problems
that interfere with the process are the usual suspects: Information integration,
communications and accountability. Many large industrial facilities have wrestled
with these problems and over time have evolved technologies for improving their
record of performance.
Tango™ provides a web based condition management system which allows condition
analysts to enter each condition problem and then integrates their results with
information from other technologies, providing a complete view of the equipment
conditions. The Tango™ Reliability Dashboard displays all pending critical
problems, their severity, aging and work order status.
Tango™ provides a standardized condition entry form (Figure 105) for analysts
to enter their evaluation of equipment problems. The condition entry form is the
same format for all condition technologies and analysis results in actionable information
which is ready for use by plant maintenance and management.
Plants using Tango™ typically use the Integrated Report (Figure 106) as a
planning and prioritization tool. Often this report is projected in weekly staff
meeting as and reviewed in detail. From the Tango™ Integration Condition Report
Details view, Tango™ allows a maintenance planner to create a work order by
copying information from Tango™ into the plant CMMS or by an automated interface
which creates a work order and receives the resulting work orders.
Once a work order is created, there may be many operational and logistical reason
it is not immediately scheduled for execution. Tango™ provides an easy to
view summary of open work orders, the length of time since the condition problem
was entered and the work order number for each condition problem.
Tango™ Provides Communication & Accountability "Plants
often struggle with knowing how well condition monitoring results are being used
to drive maintenance execution."
Many industrial plants have technically proficient predictive maintenance programs
using technologies such as vibration analysis, IR thermography and motor testing.
However, those same plants often struggle with knowing how well condition monitoring
results are used to drive maintenance execution.
All too often a plant's condition monitoring team (or service contractor) may report
on the same equipment health problem time after time for many months, yet the maintenance
organization does not respond until the equipment actually fails. Successful condition-based
maintenance organization create accountability for resolving condition-based work
The metrics begin with the Integrated Condition Status Report (ICSR). Users can
sort to show the highest severity or criticality issues at the top, and planners
can interact with the report to show that work orders have been issued or completed.
This interaction makes it convenient to update work order status, and that in turn
provides current information every time a user opens the ICAR. The "Days Awaiting
Checkoff" column provides an aging statement showing how long each identified
problem has been open; the Work Order Status" and "Work Order Numbers"
columns show whether or not work orders have been generated, and the reference number
from the plant's CMMS./ The broad distribution of this status information helps
drive the accountability mentioned earlier. Once all the condition driven work orders
for an asset component have been closed, the "Close Entry" button alerts
users that it is time for a follow-up measurement to confirm that the problem has

Tango™ Condition Entries Standardize the Reporting of Equipment Condition Problems
Just as in human medicine, it is very important that all parties use common terminology
when describing machinery health issues. Standardization of condition results mean
that everyone inputting findings and recommendations use common equipment location
names, faults, and severity levels, and that the output information has a standard
look and content regardless of technology analyst, or whether they're plant employees
or an outside contractor.
Tango's condition entry function provides a results entry form (Figure 105) that
uses pull down lists to enforce standardized terminology. This screen utilizes a
standard pull down list for the selection of faults, recommendations and severity.
The pull down lists also enforce brevity to make the information easier to understand;
an analyst can also write a more comprehensive problem description if needed. Such
standardization allows a common look and language between condition technologies,
and it also facilitates future mining of the information for common patterns. This
simple mechanism for standardizing basic finding and recommendation contact does
not exclude technical reporting, as supporting data images and documents can be
linked to the condition entry, for retrieval by interested users.

Tango TM may be used to define condition assessment tasks for specific monitoring
technologies and plant areas.
Figure 106: Condition Entry Form Detail
For example, the monthly vibration analysis for the utilities area of the quarterly
oil analysis may be defined in a Tango™ Condition Assessment Task. Task results
are specified from a menu of states. These states allow the user to define the machine's
state at the time of monitoring. Every task item must be assessed before the task
can be closed, so items missed or down must have that state assigned to them. History
of the component's health may be maintained and components which have been missed
are maintained in a special list for "at risk" components, in need of

Managing Condition Monitoring Contractors with Tango™ Reliability Management Service
IR & Ultrasonic Assessment tasks can be loaded into a PDA data collection routing.
Tango™ Web Service, in conjunction with handheld PDS's can provide well defined
survey management along with an audit trail for problems found and assets not monitored.
In addition, since Tango™ Web Service utilizes a web-hosted database on a
server so that outside plant's IT firewall, IR service contractors can use the system
and fall under this structured survey management.
The service contractor downloads a survey task into his handheld PDA then follows
the PDA screen through the sequence of panels to be scanned. A bar code scan ensures
that the IR information is being entered for the correct asset. He confirms the
asset has sufficiently loaded for a good scan, then enters the results of that scan:
•Measured, No Problem Found
•Measured, Condition Entry
Figure 108: Download Survey Task to PDA
Figure 109: Inputting Status through PDA Screen
For problems requiring a condition entry, the contractor references the IR and visual
images captured by the infrared system. Once the survey is complete, the information
is uploaded from the PDA to Tango™. Condition entries are complete for problems
found, and those results are integrated with problems found by other condition monitoring
technologies. Authorized Tango™ Web Service users can now view the updated
Integrated Condition Status through their web browser.
A plant or corporate reliability engineer can monitor the quality and completeness
of the contractor's IR work through the task summary report. This audits how many
assets were scanned, which were not scanned and what problems are being found.
