Problems with Managing Condition Information Measurement of Success Cost Avoidance/Basic Reliability Improvement Communications Many sources of information need single point for results Focus Selecting correct technologies for criticality Reporting

Problems - Condition Gate keeping work orders at planning meeting

Problems – With Managing Equipment Information How to calculate MTBF, MTBR, MTTR Data not put in system Data on paper in file cabinets Many Documents to find and maintain Root Cause difficult to get Cost of failure

Principles of Equipment Life Cycle Management Elimination of Failures in Service in Assets which disrupt production and cause high maintenance cost Increase operating life period between failures by the systematic elimination of Root Causes of Failure

Data Mining Analyze Historical data for Patterns Reliability Measurement Plant Performance

Integrated Condition Report Provides focus & communication Allows Managers to address upcoming reliability problems & measure performance Emphasis on: Which component has problems What is the problem (faults) How severe is problem What should be done (recommendations) Data is secondary & used to help visualize problem

Integrated Condition Report Contd. Browser based, easy to view, & tailored to users area Ability to view by severity or criticality Provides feedback to originator for work performed & requires validation of repair Creates Work Order in CMMS & receives Work Order closure information

Data vs. Information Plants have multiple condition monitoring & analysis systems, each is specialized for a technology. Each technology usually has one or more trained Analyst. Tango is used to gather what an Analyst knows about a problem. Integrate that with what other Analyst from other technologies know about the problem. Tango allows Management & Planners to focus on the problem & make good reliability improvement decisions. Our Customers report that Tangos ability to provide Management focus on condition problems is a major advantage.

Test & Inspection Task Management Many plant tasks require the completion of an inspection or test document to record results and preserve a record of the inspection. Breaker Testing Crane Inspection Transmitter calibration Thickness testing The Plant CMMS typically will not handle the management of these task documents. Often the plant tracks these items in home grown systems. Tango allows the definition of a Test / Inspection task, its interval, Next / Last Performance date and an Excel spreadsheet to be completed for the task.

Data Mining Using Tango Tango has several predefined data mining reports, which allow you to determine what equipment or locations are the least reliable.

Data Mining Report Listing You can use standard mining reports You can add your own custom mining report You can serve the reports via the web

How do the Equipment Measures Look? Data mining reports are drill down reports. You start at the top of a hierarchy and drill down to the levels which seem interesting.

Pick Out the Interesting Items From this level its easy to see that AC Induction motors have an MTBF of less than 3 years based on a population of over 1000 installations – much less than what is considered the industry standard.

You Can Look at Premature Failures According to the data, 65 motors were installed less than 2 weeks –thats over 6% of installed motors

Do We Have a Lemon? We can see that the piece of equipment with Plant Tag 55 was installed twice for just a single day. At this point we would want to look at the equipment history report for this motor to understand why this motor failed twice so quickly.
