Hey, Maintenance Planner! Do You Know What to Report on in Weekly Meetings?

As an Enterprise Maintenance Planner, you manage the backlog, provide a maintenance schedule, liaise with Maintenance and Operations, maintain excellent knowledge of the facility and its equipment, and find ways to optimize productivity. Phew! That’s no small to-do list.

Every day, you’re working hard to:

  1. Keep the backlog as low as possible
  2. Keep downtime to a minimum
  3. Manage an organized working schedule
  4. Successfully communicate updates to Operations and Maintenance
  5. Work towards many other tasks and goals too!

Pay $3k to Keep out of Trouble, or More to Get out of Jail

Pay $3k to Keep out of Trouble, or More to Get out of Jail

Pay $3k now to keep out of trouble or more to get out of jail later. Your plant asset performance is down and you know it. It’s only a matter of time before there is an accident. You need to improve but funds are limited. 

The expert consultants will want to begin with some sort of an assessment. They will identify problems and offer solutions, for a price (likely $50k or more). You can’t afford it. Some consultants might even be former employees. Ask yourself, “if they worked here before, then why didn’t she/he fix what was wrong when they were here?” Consider getting a different consultant but you will still struggle with a big inconvenient truth!

How Can Reliability Engineers Improve Maintenance Management

How Can Reliability Engineers Improve Maintenance Management

Reliability engineers are responsible for keeping equipment or facilities operational, extending their useful lives, and managing maintenance costs by formulating relevant maintenance management policies and programs. They offer guidance to maintenance teams, analyze existing maintenance programs to identify opportunities for improvement. Unlike maintenance supervisors, these professionals rarely engage in the daily execution of maintenance tasks. The roles of reliability engineers span the entire lifecycle of an asset beginning from the design phase, operational stage to disposal. How do reliability engineers influence the gradual improvement of maintenance management in different organizations? [Read more…]

A Mechanic’s Story: The Human & System’s Contribution

A Mechanic’s Story: The Human & System’s Contribution

In this original post, A Mechanic’s Story: Basic Component Fatigue, we took a detailed journey through the physical side of a shaft failure RCA. We stopped at the physical side of that failure, parallel misalignment. However, stopping at the component level of failure does not constitute a credible and thorough RCA. Actually stopping at this level is more along the lines of a Shallow Cause Analysis (SCA). So let’s explore what makes the difference between a Shallow Cause Analysis and a Root Cause Analysis (RCA).

In the previous post we stopped at parallel misalignment. We will continue drilling from that point down. We ask ‘How could we have had parallel misalignment?’ Our team of subject matter experts (SME) hypothesizes 1) it was either misalignment at installation or 2) it became misaligned during operations.

10 Tips for Getting the Most Out of Your Next Maintenance Assessment

Assessments are a key tool for driving sustainable improvements in you Maintenance, Reliability, or Asset Management program.

When you hear the work assessment or audit, does it send shivers down your spine?  Do you envision a week or two of some “expert” digging through your data, processes, and performance, looking to get you in trouble for something you did or didn’t do?

While some audits may be to find issues or wrongdoing, most assessments should be viewed as a key activity to improving your current programs or systems.  These assessments, are used to compare your current program to industry best practices, identifying areas which could be improved.  The assessment typically includes a Recommended Course of Action (RCOA) which highlights what gaps should be focused on first.  So, whether the assessment is driven by corporate, internally or externally, how can you get the most out of a Maintenance assessment?

How to Keep the Boss Out of Jail

How to Keep the Boss Out of Jail

Here’s a case where they didn’t know how to keep the boss out of jail! In Jan 2019, a mine tailing dam (the structure used to contain waste from mining operations) collapsed. The video below shows the event. 259 people were confirmed dead and 11 declared missing. Cause – liquefaction – a commonly occurring phenomenon, and one that this particular mine had been warned about. Outcome – fatalities and associated human cost, suspended operations (for a brief period), company reputation, criminal charges (executives and engineering consultants). Risk management is an often neglected part of our job. [Read more…]

There’s More to Maintenance Software Than Work Orders

There’s More to Maintenance Software Than Work Orders

At its core, maintenance software is a tool that allows you to generate and schedule work orders and get the right people to do each job. Maintenance software automates paper processes by enabling people to create requests for maintenance work. Maintenance workers then enter the requests into the computerized maintenance management system software (CMMS), which generates the work orders. However, when it comes to the functions of a CMMS, work order generation is only the tip of the iceberg.

The Keys To Successful RCM Implementation

The Keys To Successful RCM Implementation

If you have attended any Maintenance and Reliability conference in the last several years, chances are you have seen a presentation on the struggles of RCM implementation. Most present that over 70% of companies who attempt to get started with Reliability Centered Maintenance fail to implement the recommended mitigating tasks identified in their analysis.

What Happened?

What Happened?

As many of you know, I have been encouraging my LI contacts for years to take me up on my offer to review any pictures they have of failed parts, and we would try and provide them some preliminary feedback. Well, someone finally took us op on the offer and we wanted to share what was learned (we obtained permission to do so providing the company name was not used).

Here was the original inquiry via LI instant messenger along with the pictures:

“Dear Sir, As per your advise, I’m sending you a photo of failed flange bolts. I belief they were failed due to fatigue. Could you please review them and identify/ label their failure mode. After your comments on this photo, I’ll put up a recommendation on my RCA. Looking forward to hear from you. Regards.”

Building a Recommended Course of Action

How to Translate an Assessment into an Action Plan

An assessment was performed and many opportunities identified, but it has been three months, and nothing has changed.   Does this sound familiar?  As discussed in a previous post, the goal of an assessment is to identify gap to best practices and provide the basis to develop a plan to move forward.   However, many times an assessment is performed, the results put into a binder and put on the shelf (does this sound like your RCM initiative?).

Is There a Direct Correlation Between Reliability & Safety?

Is There a Direct Correlation Between Reliability & Safety?

“Assumption 1: Safety is increased by increasing system or component reliability. If components or systems do not fail, then accidents will not occur. (p. 7)

This assumption is one of the most pervasive in engineering and other fields. The problem is that it is not true.

Safety is a system property, not a component property, and must be controlled at the system level, not the component level. 

New Assumption 1: High reliability is neither necessary nor sufficient for safety. (p.13)”

These statements were excerpted from Nancy Leveson’s “Engineering a Safer World“. 

This contradicts the common belief there is a direct correlation between Safety and Reliability. I personally, being in the Reliability field for 30+ years, believe there is a correlation between Reliability and Safety. But I would assert that it is not a direct correlation.
