Feature Article - The Central Issue

During the 90's, many plants have decentralized maintenance to a greater or lesser extent. While these plants have seen many gains from being closer to the consumer of their maintenance services, they also see issues emerging. What are the criteria to choose central vs. decentralized maintenance? Which functions and activities are candidates? This article, from Bradley Peterson of Strategic Asset Management Inc. discusses these issues. You will find it at http://www.plant-maintenance.com/articles/Central_Issue.pdf. Note that you will require the free Adobe Acrobat reader to be able to view this file.


Feature Article - Open Warehouse System

The world's largest combined cycle power plant on a single barge, and, India's first and the only barge mounted power plant set up at Mangalore coast set up by GMR Group, a renowned name in Infrastructure Sector. The plant had all the traditional elements of Lean concept - A lean human organization structure, lean operation cycle, a single-segment raw material supplier and a single segment market for its Power. Added to this was the Open Warehouse System,

This article, discussing this open warehouse system, was contributed by H. Lakshminarayan and can be read at

Feature Article - Centrifugal Pumps: Basic Concepts of Operation...(Part II, Understanding Cavitation)

This is the second part of this article, from Mukesh Sahdev, Associate Content Writer at The Chemical Engineers' Resource Page, www.cheresources.com. The title is fairly self explanatory. Due to the size of this paper, it has been split into two parts, and can be viewed at http://www.plant-maintenance.com/articles/centrifugalpumpsb1.pdf.and http://www.plant-maintenance.com/articles/centrifugalpumpsb2.pdf..Yet again, you will require the free Adobe Acrobat reader to be able to view this file.


Feature Article - A Survey On Condition Monitoring Systems In Industry

This article written by Philip A. Higgs, Rob Parkin, Mike Jackson, Amin Al-Habaibeh, and Jo Coy was first presented at ESDA 2004, 7th Biennial ASME Conference Engineering Systems Design and Analysis, and is kindly reproduced here with the permission of ASME.

Advances in networking technologies are opening integration opportunities for Condition Based Monitoring (CBM) systems, presenting further possibilities for increasing CBM system functionality. This paper presents the results of a CBM Survey designed to determine present applications of CBM systems within industry.

2004 CMMS Implementation Benchmarking Survey

Our CMMS implementation survey closed recently, with responses from over 100 people. The key findings are:

  • The five most common CMMS in use were SAP, Maximo, MP2, MIMS/Ellipse and PMC.
  • In comparison with our 2000 survey on this topic, there are significantly more SAP users and significantly fewer MP2 users in this survey.
  • Most systems have been in place only for a few years, but a significant proportion have been in place for 5 years or more
  • Statistical analysis of responses showed no clear correlation between the conduct of other usual change management activities associated with CMMS implementation, and the perception of implementation success
  • The most commonly stated reasons for selection of the current CMMS were General functionality and features and Integration with other commercial software
  • In comparison with our 2000 survey on this topic, Integration with other commercial software was a more significant factor in the selection of the CMMS
  • CMMS are seen as being moderate-to hard to use, on average, with Maximo rating highest in terms of ease of use
  • CMMS are, on average, seen as being only moderately well endowed with functionality and features, although SAP and Maximo rate highly in this area
  • CMMS implementations are generally seen as moderately successful, with little variation between ratings for the top 5 most popular CMMS packages
  • Most of those respondents who rated their implementation as poor had implemented packages other than these most popular packages
  • In comparison with our 2000 survey on this topic, relatively fewer implementations, overall, are rated as being Poor
  • The most important factors in implementation success were obtaining Senior Management committment, and effective training. The relative importance of slecting the correct CMMS appears to have declined over the last 4 years.
  • Overall, most respondents reported that their CMMS implementation has led to some or significant benefits

Maintenance Survey Survey!

This is our simplest survey yet. It consists of one question - what topic would you like covered in our next survey?

You can complete the survey, and view the results to date, at http://www.plant-maintenance.com/survey.shtml. The survey will remain open until November 15, 2004, and we will announce the topic for our next survey in our November newsletter.


Book Review - An Introduction to Predictive Maintenance by R. Keith Mobley

If you plan to buy one book on Predictive Maintenance, this, I believe, is currently the best book on the market. This is not to say that it does not have its shortcomings, but overall, this book comes closest to being a comprehensive introduction to the Predictive Maintenance technologies currently available, and their practical application. You can read our full review at http://www.plant-maintenance.com/books/0750675314.shtml


Recommended Books

Here are ten Maintenance-related books that we have reviewed recently, and strongly recommend:

On the Lighter Side - Engineering Humor

The Maintenance Engineer

He stood before the pearly gates
His face was scarred and old
He stood before the man of Fate
For admission to the fold
"What have you done", St Peter asked
"To gain admission here?"
"I've been a Maintenance Engineer
For many and many a year"
The Pearly Gates swung open wide
St Peter touched the bell
"Come in and choose your harp my friend:
You've had your share of Hell".
