Spending the right time on the right activity. Today this is all about time management and how to organize and plan your time out. this is a significant skill for more than just one role within the maintenance organization.

For many in the maintenance field, the day-to-day tasks can feel routine. Fix a leaky faucet, replace a worn belt, and ensure everything is running smoothly – it’s a process that becomes second nature. But beneath the surface of these seemingly straightforward actions lies a critical component that can safeguard both worker safety and equipment longevity: the MSDS sheet, also known as the Safety Data Sheet (SDS). Let’s learn what does MSDS stand for. [Read more…]
The only true way to prevent asset failure is to prevent the causes of microstructure failure from occurring.
Machines fail when their component’s microstructure is degraded or deformed to a point where it can no longer bear the load. If you prevent degradation and deformation from occurring a machine and its components will provide an exceptional lifetime. However, you must do this at every phase of the asset’s life cycle to get world class reliability.

Adding equipment redundancy to a system can improve uptime and reliability leading to increased output. When adding new equipment, it is cheaper to evaluate the benefits, or lack of thereof, on paper before implementing the change. Typically done as part of the design phase. However it can also happen after commissioning but its is more expensive. In other words, its better to get it right before “shovels go in the ground”.

How the 3T’s of Human Error Prevention and Mistake Proofing – Target, Tolerance, Test – were Discovered
Human errors and mistakes cause 80 percent of industrial equipment failures. That humans cause most problems has long been known. It has been difficult to find reliable ways to prevent human error, but an Arab craftsman taught me the 3Ts of error prevention and mistake proofing work.

This job description begins detailing the attributes, skills and knowledge required for a person to competently do the duties of a maintenance planner focused on improving equipment reliability. It uses an outcomes approach to set the standards that must be reached in the performance of the work. It leaves the person doing the job the flexibility and initiative to find their own way to reach those standards.

George Williams and Ramesh Gulati discuss the importance of Reliability Engineers in the work space. -Why is Reliability important? -What does it take to be a Reliability Engineer? -What type of skillsets are needed? -Why is it important to have Reliability Engineers?
[Read more…]Paul H. Barringer invented the Barringer Process Reliability (BPR) process. Paul was a fellow Reliability Engineer “extraordinaire” and an outstanding mentor for myself and countless others in this field of practice. BPR highlights operational issues. If not addressed or mitigated, those could have significant revenue impacts on an operation. A BPR analysis uses the Weibull probability plot which happens to be a very well-known tool in the field of Reliability Engineering. On one side of a sheet of paper only, the BPR plot can tell the true “story” on the operation. One of those “stories” relates to high impact events best tackled by a Root Cause Analysis.

What Every Manager Needs to Know About Business Risk from Equipment Reliability
Figure 1 shows how equipment risks start and transfer through a business. Tens of thousands of business risks, even hundreds of thousands in big operations, come from your plant and machinery.

I have led internal maintenance teams towards world class reliability, I have outsourced specialized maintenance functions (predictive technologies) and I have worked with companies outsourcing all maintenance.
Maintenance outsourcing continues to grow with 65% of large companies outsourcing some maintenance..but perhaps for the wrong reasons.
A parametric Life Analysis involves “forcing” or “imposing” a distribution’s parameters on a data set in order to obtain the “best fit”. However, it can lead to errors in results. The non-parametric estimation suggests that there are other approaches though not necessarily the easiest or “most elegant” ones. In the field of reliability engineering, we tend to like something so much that we use them in every “sauce”. A classic example is the Weibull Distribution. It has become so popular that Life Analysis is also known as a “Weibull Analysis”. As a reminder, the Weibull distribution is only one parametric distribution amongst a myriad of others, invented by Walodi Weibull in 1937. Dr Bob Abernathy’s New Weibull Handbook1 quotes: “the Weibull distribution provides reasonably accurate failure and failure forecasts……”. Thus, parametric distributions are good enough but not perfect to make a decision.
