Your Reliability Engineering Professional Development Site
In the petroleum, natural gas and petrochemical industries, great attention is being paid to safety, reliability, and maintainability of equipment. This is true in any industry and as such the learnings and information found within ISO 14224 can be applied to any industry. [Read more…]
Let’s face it, your technicians have been entering data into the CMMS for years, but you haven’t been able to use it to make improvements. Is it because the data isn’t codified or it doesn’t have the right data points? Generally, this is how most maintenance managers will view their data, but it is incorrect. The CMMS does have data that you can use almost immediately. [Read more…]
A failure has just occurred on a critical asset in your facility. The result was 2 hours of lost production, but it could have been worse. The last time that the equipment failure occurred it took 5 hours to repair. Why was the failure repaired in less than half the time than the previous occurrence? How can we ensure that we learn from this failure and the team’s performance to improve the plant performance?
I remember reading about a simple philosophy quite a few years ago (although I can’t remember who stated it, so I apologize that I cannot provide a reference), about a simple analysis that can be applied to any maintenance activity to improve performance. This analysis is call the 2 Up / 2 Down analysis.
The 2 Up / 2 Down analysis is quite simple and involves asking two questions.

Many organizations try to improve performance by just creating PM routines and letting the technicians loose to perform the work. This often has negative effects on plant performance. This has been proven through studies conducted by Ledet at numerous DuPont sites. This study looked at the impact of Planning, Scheduling and Preventative Maintenance on Plant Performance.
Ledet had found that by just implementing a PM / PdM program, organizations lost 2.40% of uptime (on a baseline of 83.50%). Not quite the results to expect when implementing a strategy to improve plant performance. When the PM / PdM program is implemented with Planning & Scheduling, the plant saw an increase of 5.10%. Now that is an improvement.
But what about the remaining 11.40% of uptime? How does one address the remaining downtime?
