Bridging the Gap Between Condition Monitoring Reports & Maintenance Action
Tango Web Service, in a supplemental role to the plant’s CMMS system, can streamline the flow of equipment condition status between analysts, reliability engineers, and maintenance planners.
Managing Motor Reliability
The lifecycle tracking and reliability improvements of industrial electrical motors is difficult, primarily because the necessary information comes from a wide variety of sources including: purchasing, installations, condition analysis, stores, and repair vendors. The Tango equipment lifecycle management software produced by 24/7 Systems is a proven method of maintaining needed information and measuring motor reliability. In order to improve motor reliability, you must be able to measure it.
Managing Reliability Across the Corporation
This paper will discuss how two major food and beverage corporations use an internet-based communication service to create consistent operations and information flow in condition monitoring activities at their different plant sites, even when outside contractors are providing monitoring services. Discussion will include:
- Managing frequency & completion of monitoring tasks
- Standardizing reporting & metrics of reliability progress across the corporation
- Role of internet-based communications in creating consistent corporate accountability for reliability improvement
Putting All the Pieces Together
Condition Management Analysis and Program Metrics
As condition entries and assessment tasks are processed through Tango™, plantwide and area specific condition based maintenance metrics are produced.
Setting Up Lubrication Results in Tango™
Lubrication routes typically concentrate on validating that grease lubricated machines have been successfully greased and over greasing has not occurred and that oil lubricated machines have adequate lubrication and the lubricant is not contaminated.
Routine Inspections Play a Key Role
Routine Inspections Play Key Role in Condition Based Maintenance at Buzzi Unicem. Points discussed will include:
- Maintenance Inspections are Automated with PDA’s
- Observations are Merged with PDM Results
- Integrated Condition Information Guides Work Priority
Reliability Information Management: What is It & Why Should You Care?
Many maintenance professionals agree that there are two basic reasons for the focus on reliability in industrial plants:
1) Eliminate unexpected equipment failure that can interrupt production and carry high repair cost, and
2) Extend the life of equipment between repairs to lower total lifecycle costs.
To accomplish these goals a plant must implement and manage many condition monitoring, lifecycle tracking, and failure analysis activities.
Accountability and Communication
The goal of equipment condition monitoring is to increase equipment availability, yield, quality, and reduce maintenance cost by eliminating in service failures on critical equipment, extending the life (reliability) of plant equipment and by eliminating costly prevention (scheduled) maintenance work when condition analysis shows no need for the work.
Plants have invested heavily in condition monitoring technologies such as vibration, oil analysis, thermography, and motor circuit evaluation to provide an accurate prediction of plant equipment problems. Most plants put significant time and resources into measuring equipment condition, and then much of the information is never acted upon – What’s up?
Often the problem is that condition based maintenance programs are begun by corporate or plant managers and never get “buy-in” from plant maintenance. When plant maintenance supervisors are asked why they do not act on condition based results you can hear many excuses like:
- Do not believe the results
- Not enough time
- Lost or did not look at the report
- No money – costs too much
- Operations will not allow repair
- When a machine fails they are the hero and receive overtime
Many plants have noted that it often takes a catastrophe to get maintenance buy in for condition based maintenance. Some innovative plants have found that a consistent program of communication and accountability have made the implementation to condition based maintenance easier and faster.
Managing Condition Monitoring Contractors and Their Results
Many industrial facilities have chosen to use condition monitoring service contractors to apply predictive maintenance measurement technologies and produce reports on degraded equipment condition. Often different contractors are utilized for different PDM technologies resulting in reports with different styles, fault names, severity scales and equipment IDs. Also the ability to integrate these results is non-existent.
This paper presents strategic case history accounts that illustrate the implementation of a web-based system to manage condition contractor work and results. The use of this web-based package allows the subcontractors to post their condition status into a single integrated database without having to deal with plant IT firewalls. Benefits include:
- Standardization of equipment names, fault descriptions, and severity scales
- Integration of all known condition information for each monitored asset
- Communication of results to a broad audience of plant users via the Internet
- Accountability for timely performance of scheduled condition tasks and maintenance follow-up
- Performance Metrics that indicate progress (or lack thereof) toward reliability goals
24/7 Systems produces the Tango Condition Management Web-service that is used by several plants to manage and integrate their contractor produced PDM results.
Strategic Component Management
Strategic Equipment Management is an industrial maintenance strategy for actively managing critical high value rotating machinery for highest reliability, lowest life cycles cost, and minimizes production losses. The goal of strategic equipment management is to increase a machine’s reliability, lower its maintenance cost, and increase production availability. This strategy, when aggressively implemented, can substantially increase a plant’s profit margin.
