An Introduction to RCM

1 The Changing World of Maintenance

 Over the last twenty years, maintenance has changed, perhaps more so than any other management discipline. The changes are due to a huge increase in the number and variety of physical assets (plant, equipment and buildings) that must be maintained throughout the world, more complex designs, new maintenance techniques and changing views on maintenance organisation and responsibilities.

 

An Introduction to Time Waveform Analysis

In recent years there has been a resurgence in the use of time waveform analysis techniques. Condition monitoring personnel have now come to realize some of the limitations of the FFT process. Since many find the time waveform analysis process difficult and confusing the technique is rarely used to its full potential. The key to the successful utilization of time waveform data is knowing when to use it. This paper examines the limitations of the FFT process and identifies specific applications where enhancing FFT information with time waveform analysis is appropriate.

The paper also details in practical terms how to set up, acquire and manipulate time waveform data. Having discussed the acquisition of the data the paper continues to discuss the interpretation of the data including the time-frequency relationship, symmetry, and pattern recognition of common faults.

An Overview of Remote Machine Condition Assessment

by John Bernet

Fifty years ago, when labor costs were relatively low compared to operating expenses, managers found that they could simply use more staff to cover the increasing demands of maintaining plant machinery.

Analyzing and Quantifying Your Company Asset Management Opportunity

A methodical approach to measuring your company's current reliability profile and establishing your "Asset Management Opportunity" in dollars and cents for upper Management by James W. Davis, PE, SAMI 

APEX™ - Benchmarking Performance Culture

A typical Monday staff meeting; the coffee is cold and someone is droning on about how important it is to improve operations. Productivity is drooping and the charts on the wall look terrible. A benchmarking study is suggested and all agree that knowing where you stand relative to your competition is a great idea. You get assigned the task of pulling the numbers together for the comparative study. The meeting adjourns; you trek back to your office wondering where you will get the required data.

Applying Power Quality Measurements to Predictive Maintenance

You may already be using predictive maintenance (PdM) techniques on your motors and drives. But how often do you inspect the power to your equipment? By adding basic power quality measurements to production equipment maintenance procedures you can head off unexpected failures in both production equipment and your power system.

Applying the Guidelines of BSI PAS 55 to Facility Management

The emergent understanding of asset management across all industry sectors has triggered a subsequent need for a standardised approach. The Institute of Asset Management (IAM) in collaboration with the British Standards Institute (BSI) and other industry groups first developed PAS 55 - Part1: Specification for the optimized management of physical assets in 2004. This was developed in response to industry demand for a standard for asset management and was recently revised in 2008 following international collaboration from industry and asset management associate groups.

Arc-Flash Protection - Understanding NFPA 70E

By John C. Klingler, P.E. Lewellyn Technology

Note: John presented a short course on this subject at IMC-2005 December 6-9, 2005 in Tampa

You have decided to conform to the requirements of NFPA 70E, the standard for Electrical Safety in the Workplace. You already have an electrical program for preventing shock; here is an explanation of how to address the 70E requirements for arc-flash.

Are the Improvement Tools Working? A Survey of Practices

Over the past year I've worked with Terry O'Hanlon to do a series of webinars on the most popular tools in the market place for improving manufacturing/operational performance in industrial plants. As part of these webinars, we've asked participants to answer a set of questions related to their practices to get a sense of how well they were working. Many of their responses were encouraging - 42% are working to apply lean manufacturing principles, of which 70% of those say its working; many are using the various tools in a sustainable way. And, more than 95% rated safety as a top priority.

Assessing the Cost of Unreliability

It is best to begin a reliability assessment with an evaluation of the overall cost of unreliability. In this context, I am using the term "cost of unreliability" to mean the overall cost resulting from all situations caused by reliability-related failures. This cost will include both the direct and indirect costs associated with all reliability issues that could have been prevented by adherence to good reliability practices.

Asset Integrity: What to do after an Economic Crisis

Being Prepared

Most companies have reduced cost during these tough economic times in order to survive, shutting down equipment, lay off staff, extending time between rebuilds and preventive maintenance without thinking about the preparation they should be taking in order to take advantage of the economic turnaround. There will be winners and losers once the world economy turns around. Companies who are prepared will win by shutting down their competition, demonstration profits never heard of before. This can be obtained by focusing on "optimizing asset integrity at optimal cost".

Availability

A tool for measuring the % of time an item or system is in a state of readiness where it is operable and can be committed to use when call upon. Availability ceases because of a downing event which causes the item/system to become unavailable to initiate a mission when called upon. In the simplest view the metric is availability = uptime/(uptime + downtime). For many other definitions see MIL-HDBK-338, section 5.
