A corporation is a living organism; it has to continue to shed its skin. Methods have to change. Focus has to change. Values have to change. T he sum total of those changes is transformation.

Rules for Reliability is by Terrence O’Hanlon, CMRP, and is based on W. Edward Demings 14 Points from “Out of Crisis”. Terrence O’Hanlon is the Publisher of Uptime® Magazine and Reliabilityweb.com. www.reliabilityweb.com
25 Years Ago: Assets typically referred to an individual’s or company’s financial portfolio. 20 Years Ago: When someone spoke of Assets it usually referred to the IT Group and their putting barcodes on all the computers. This was an accounting and IT Group responsibility, not a problem for the Maintenance Manager. 10 Years Ago: Maintenance Managers began hearing about Asset Productivity Improvement, Maintenance Optimization and/or new ERP, EAM or CMMS systems. The focus was definitely on reducing the rising cost of equipment maintenance and improving equipment reliability. Today: When we speak of Assets today in the US we are probably talking about the crumbling infrastructure and the need to invest TRILLIONS of dollars to repair or replace them, i.e. failing bridges, rails, highways, airports, distribution networks (oil, gas and electric) and water & sewer systems. The consensus of insurance, investment and consumer stakeholders and regulators is in. Equipment reliability just isn’t enough anymore. Tomorrow: Will your company be able to attract the investment dollars needed to rebuild your business? Will you even be able acquire insurance let alone be able to afford it? Your ability to demonstrate good governance through the development of policies, strategies and plans that address these concerns while satisfying your corporate business goals will differentiate you from others seeking their share of the pool of investment dollars. PAS 55: These are some of the drivers behind the development of PAS 55 and why I’m excited to be part of the vanguard introducing it to America. Boyd Beal, CMRP, Vilinc Solutions, Inc.

auditing Training is an essential part of any maintenance and reliability program. When applied to a predictive technology, it is essential that a technician be properly trained in techniques when utilizing vibration or oil analysis. However, it is equally imperative that a technician be audited in their use of the technologyâ€™s methods. How often has a technician been sent to training and received their certification, only to return and not completely understand how to apply what they have learned.Â One can combat the issue of proper technique through auditing practices sourced by internal personnel or external consultation. The size of your maintenance team and available expertise will dictate how this is approached. Technique auditing can be a useful learning tool to increase tribal knowledge through the use of documented procedures. Improper technique can lead to inaccurate results. Inaccurate results can lead to a missed opportunity to prevent a failure and that can kill any maintenance program.Â In order to perform a technique audit, a proper procedure for performing the tasks must exist. These procedures must be readily available and easily understandable. (Remember: the average person reads at a 7th grade level, procedures should not be geared towards a rocket scientist). Personnel should have received previous hands-on training for performing the task properly. You do not want to subject someone to an evaluation if they have never seen a procedure or performed the task. When evaluating, look for deviations from the procedure for the task being performed. Having techniques in place that replicate what is outlined in a procedure leads to accurate results. Accurate results are a driving force with any maintenance program. Auditing personnel can lead to achievement of proper technique therefore accurate results. Utilizing expertise for the purposes of auditing enhances the program through the enhancement of personnel performance. Stacy Heston is the Field Services Manager with POLARIS Laboratories.

Awaken To be asleep is to be unconscious or unaware. Some people live their entire lives asleep; unaware of the effects of their actions. They simply follow the well worn paths of a daily routine, blame others—and wait. When we become aware we must act. We may ignore the issue or face it; either way, awareness implies responsibility. We cannot pretend to have not seen what we have seen. To be curious and to inquire is to begin to awaken. It is an attempt to understand the things around us. Why did that machine fail? Why are we always stressed out and backlogged? How does this work? How can this be done better or more efficiently? Attend courses! Read books! Ask questions! The world opens up to the curious and becomes a rich and vibrant place. We become less bored, happier and more fulfilled. But we have to learn to listen and also to say: “I don’t know” Observe yourself. When you interact with your boss or coworkers what are you bringing to the table? Are you trying to help or are you trying to win? Is it about solving a problem or is it really about you; your status; your desire for reward or your fear of punishment? Seeing ourselves as we are is difficult but essential. We cannot do this effectively on our own,
and we often won’t do it unless we have no other choice. Proactive maintenance, reliability and uptime are related to our interpersonal relationships, physical and mental health and happiness. We improve them all by being awake, aware and personally responsible. Problems “outside” are sometimes best solved by looking inside ourselves and being honest. Wake up in 2010 and do good things for yourself and others! Alan Friedman has worked in the field of vibration analysis / condition monitoring for 19 years.

certified? Why Qualification/Certification Testing is Needed for Shaft Alignment: • Shaft misalignment continues to be one of the most prevalent root cause failures on rotating machinery. • Most people who perform alignment have not received adequate training. • The people who supervise employees responsible for alignment typically had no training or alignment experience. • Think that purchasing an expensive alignment measurement system will eliminate alignment problems. • Allow contractors to install rotating machinery who are not qualiﬁed to align the equipment. • The vast majority of people who are required to align machinery do not know: • • • • •
How to detect a misalignment condition when the machinery is operating. How to ﬁnd and correct soft foot conditions. How to ﬁnd and correct excessive runout and piping strain. That there are ﬁve basic shaft alignment measurement methods. That there are thirteen different techniques to measure off-line to running machinery movement. • That the stationary—movable alignment concept can significantly increase the amount of time needed to align machinery. • Don’t know how to model off-line shaft positions and thinks that rotating machinery stays aligned forever.
The need for qualification/certification testing in specialized tasks such as vibration analysis, thermography, and shaft alignment is justifiable. Establishing the requirements for qualification or certification can be accomplished by appraising the experience level of personnel through an evaluation form that addresses all of the aspects of the task. Skill requirements for each individual can then be assessed and appropriate training can be administered. Written/ oral exams and/or task simulation tests can then be conducted to determine the true proficiency of the individual. Certification examinations can be used as an effective tool in verifying an individual’s level of proficiency in any speciﬁc task and a viable mechanism to let someone know where they need additional training. Prove you’re proﬁcient, get certiﬁed now. John Piotrowski is the author of Shaft Alignment Handbook.
challenge Reliable Manufacturing is a constant challenge. Every day we have to strive to eliminate waste, produce more with less and outpace our competition. Would it not be great if we could practice before the big game? Now we can. Check out the simulation at http://www.abb.com/reliabilitychallenge. Once you try the Reliability Challenge read on to learn some of the key points to improving your score both online and within your plant. We have grouped the elements into three areas: creating a reliable foundation, changing a plant’s culture, and ensuring sustain ability. Creating A Reliable Foundation To win the Reliability Challenge, you must start with a structured foundation of core elements that are built in a specific order that’s not arbitrary or ad hoc. For example, a company would not implement advanced Predictive Maintenance (PdM) techniques if they did not have proper work control processes, ensuring that the identified defects could be planned, scheduled, and eliminated or mitigated. Simply put PdM without an effective work execution process is like helicopter without a propeller; it may look nice and shiny but it is not going to get you off the ground. Changing The Culture Similar to the real world, taking short cuts in the Reliability Challenge is a recipe for failure. The plant did not morph into its current state overnight, nor will it be fixed in a 24-hour period. Take the time to create a master plan that takes into account your project, risk, and communication plans. Don’t rush the change if the resources are not available and take the time to understand the dynamics of change. You do have to be reactive to get proactive, but reactive in a smart way. Ensuring Sustain ability In order to sustain improvements, you must ensure that the facility understands the goals. Once goals have been established, use metrics to insure focus. Once metrics have been established it is important to drive continuous improvement, as some elements naturally degrade over time. Lean, Six Sigma
and RCM—all of which are represented in the Reliability Challenge—provide the processes and tools for continuous improvement. In Conclusion… There is not one way to solve reliability or plant issues, just like there is not one single path through the forest. However, when you have a foundation built on best practices, a clear plan backed up by good change management, and established continuous improvement; you have the winning combination to conquer the challenge. Now don’t forget the most fundamental rule of any game: practice makes perfect! Enjoy the ABB Reliability Challenge and practice the game of change, so you can win our Reliability Challenge and yours!

change Managing complex CHANGE within an organization can often times be very time consuming and often results in less than desirable results. Using the chart below as a guideline can help make sure you have all of the components to effect change. It can also be used to troubleshoot areas of deficiencies in your program, project or CHANGE efforts based upon the type of results you are achieving. So if you are missing any of the key components or these key components are not clearly defined, your results will be less than the desired CHANGE.

choices Here are some thoughts to see you into 2010 and beyond, no matter whether starting a new project or a new role. Life is a journey of a series of roads filled with many options and blind curves. Your challenge is to leave behind a great legacy with all those you encounter even when reaching a crossroads, like a different employer. When it comes to your integrity and trust, even when some might suggest otherwise; always take the high road. Choose differently and it’s an easy slide into the ditch. When the path is not clear, choose the road that becomes an enabler, tactfully showing passion and conviction. Stick to your core values and beliefs. Look positively toward opportunities for change. Use the opportunities to reinvent yourself, to leave failures (baggage) behind, and to carry forward the successes. Be a continuous learner. With corporate downsizing, they can’t take away knowledge gained. Use it to build the wisdom that enhances your ability to navigate. Also, you don’t always have to map the road forward from a leadership perspective but if you don’t, the path traveled never changes. Along the journey, you will encounter many people. It’s you who must take responsibility for the relationships. Every turn on the journey equates to a decision that makes some happy and someone else sad. Keep your friends close and hopefully, your few enemies even closer. Recognize you are the shepherd of the flock. You must foster the growth and well being of those you lead, to mutually serve and respect. Guide your conscience by checking your reflection in the mirror frequently. Most importantly, ensure that your priorities are properly aligned. Strike a balance between work and your life. If you don’t have your health or your family, not much else will matter in the end.

communication Communicating is something we do every day with everyone we encounter, but how well are we actually doing it? There are four common components in the communication process: the Sender, the Receiver, the Message, and Feedback. However, in order for these components to work together properly it is necessary to avoid ASSUMPTION. A key source of breakdown in the communication process begins with the assumption that someone already knows the message, the message was properly understood, or the correct person received the message.
The Sender is the originator of the message. The Receiver is the person the message is sent to. The Message is the idea or information being sent. The Feedback is the interpretation of the message the Receiver returns to the Sender. To ensure that the message is understood the Sender should listen for Feedback from the Receiver. If the Sender assumes the Receiver knows the message, the message may never be sent. This assumption has caused a breakdown in communication. If the Message was “remove x piece of equipment from service because of a severity 5 oil analysis result,” the Receiver may not be aware of the sample result and the equipment would remain in service. This may lead to catastrophic failure of the equipment. If the Sender conveys to the Receiver, “remove x piece of equipment from service because of a severity 5 oil analysis results,” the Sender is responsible to listen for feedback or a paraphrase of the Message from the Receiver. This will eliminate the assumption that the Receiver heard the Message, and avoids the possibility the Receiver heard “remove Y piece of equipment from service...” Feedback allows for verification of a properly received Message. A properly received Message is interpreted correctly and received by the right person. Stacy Heston is the Field Services Manager with POLARIS Laboratories.

compassion In my years of conducting root cause analysis investigations, I often get the sense that leadership is most interested in finding a “guilty party” and punishing them. Leadership then feels satisfied because “something has been done to prevent recurrence.” It is extremely important to prevent recurrence when there has been an injury, a dangerous environmental release, or a major plant outage. But simply punishing an individual does not prevent others from taking the same course of action in the future. No amount of fear will prevent human mistakes. So we must go beyond the human mistakes (call them inappropriate choices at critical times) to a place of understanding what encourages inappropriate choices, or discourages appropriate ones. This is the realm of systemic causes (latency, managing systems, etc). We must find out what influenced the person to choose the action, or lack of action, s/he did. If we really, really understand how the workplace environment affects workers’ behavior, AND if we imagine ourselves in their shoes, we will usually confess, “Given the same set of circumstances, I would have done the same thing.” Whenever this is the case, punishment is not appropriate because the situation could have happened to anyone. This is what I mean by compassion. Compassion
is the absence of self righteousness. Instead, we must each look to how we contributed to the incident or injury. Every member of the investigation team should assess what they could have done differently in the months, weeks, and days preceding the incident that might have prevented it. Then blame is shared; then everyone has incentive to prevent recurrence. This includes the extended team: Maintenance, Operations, Procurement, HR, and Engineering leadership. We must ask ourselves these questions: Did I lay out clear expectations? Did I enforce rules consistently? How did I respond to requests for change or assistance? Did I ignore small problems that led to this large incident? Is our training actually effective? In summary, effective root cause investigations will uncover the ‘why’ component of human error and will include everyone acknowledging their share of the responsibility.

costs The current economic climate dictates that cost management is a critical activity for many companies and their managers. Maintenance is very often seen as an area where cost cutting targets can be easily and quickly achieved. Many maintenance managers take the view that this type of philosophy always ends up with increased costs in the future. This is not true in many cases. Methods of Reducing Cost without Increasing Risk Select a system or equipment item. Document the existing maintenance program (formal and informal), including operator rounds List the maintenance tasks on a spreadsheet or PMO2000® software. Provide some conceptual training in the RCM Decision Logic. Note that it is important to keep away from complex statistical methods if you want people to believe in the results. Keep it simple. Discuss operating context of the equipment being reviewed. Then establish the failure mode(s) that each task is meant to find (in the case of hidden failures), prevent or predict (for both hidden and evident). Review the list to establish two important outcomes. The first is to find tasks that represent duplication of effort and the second is to establish what failure modes are missing from maintenance program. The latter is derived from a review of failure history (documented or in memory), and a detailed walk through the documentation associated with the machine. Analyze each unique failure mode individually and apply RCM decision logic to create a revised PM program. Then identify the most costly maintenance and think of ways to eliminate it through redesign. For evident failure modes that are random and sudden and cannot be treated with preventive or predictive maintenance seek ways to eliminate or minimize the consequences of them. Revise your data gathering system using the method described in another section. As the new program is deployed, reactive maintenance reduces and the total cost of maintenance reduce; very quickly in some cases. The cultural dimension
of the company also improves with less chaos and the ability to produce quality maintenance rather than a fix it quick / temporary repair approach. Our evidence strongly supports the notion that morale and motivation impact greatly on the productivity of companies and the unit cost of production. In today’s current economic climate a company’s very survival could well depend on its ability to reduce its maintenance costs while not sacrificing its viability in the long run. The important point is that cost reduction should be achieved through proven methods rather than methods based on knee jerk reactions and management decisions based on a variety of assumptions that are intuitively appealing but may prove to be wrong. From a maintenance manager’s perspective, it would seem better to be in control of cost reduction than have arbitrary targets imposed.

educate Today’s economy is no reason to simply let down your guard. That is to say, now is not the time to not train your employees. Employees need to be kept abreast of the latest trends and/or practices within a certain filed or technology. There are Masters of Technologies, individuals that bring within a field of study or technology information or practices without the bias of a company or an individual paying for that information. Today’s technicians need the wisdom of those that came before them. Masters of a technology that have the experience and desire to continue to teach and/or instruct those individuals that are out their every day trying to not only perform with excellence but to give it everything they have. I know of several technicians that are extremely proud after attending a class on ultrasound, vibration analysis, infrared thermography or oil analysis. Proud that their company used what might truly be called today a “limited” resource to train them. I have listened to these technicians talk about their companies in a positive attitude, an attitude that only exemplifies today’s modern technicians wanting more than ever to keep their jobs and keep their company competitive. When we look at the global world market and how we as Americans are suffering from the many companies that once made America great and how they have left our shores for foreign soil, foreign workers, and from restrictive conditions that hamper growth and competitiveness. We can only look at ourselves and the education of the American worker. A society exists today of individuals that believe in lowering the education standards of our children even further than they were just a year ago, particularly in mathematics. I for one know the bias of those that held others back in the 1950’s, so that others could catch up. That was wrong then, and it is wrong today. The education of your technicians will forever relate to our competitiveness in the world global market. Educate, and you will without fail, become more competitive and you will build a better relationship with your employees for a better tomorrow.

education!! Educate yourself. Knowledge is power!! When you have the knowledge, the skills and the experience you have the power to make the right decisions, if not the right decisions then at the least very educated ones. It seems the Maintenance and Reliability world is driven by vendors or consultants, touting how their way is the best way, sometimes the only way. How do you overcome this bias, educate yourself? Understand the terms. There are several ways. First and foremost, in my belief, is to read. Read everything on the topic you can, this is the most cost effective route today, it doesn’t require the travel and lodging required to get to a conference, it can be done in the comfort of your office or home couch, you can highlight the points that make the most impact on you in the book for future reference. Maintenance and Reliability Best Practices is the best I have read on the most complex of topics you will run across in the maintenance world, with some very good points to be reckoned with. There are a multitude of magazines with many articles, with tons of links to supporting material.
Second, there are a ton of good blogs on the web on this topic (set up your own web page to capture the important ones, so when you log on during the day there they are with the latest updates, this was pointed out to me and it works). Third, attend webinars, they are usually free and are put on by vendors or are supported by vendors to promote their product, but there are kernels of information in all of them, again you can stay at home, spend your hour or so listening, again cost effective rules the day. Four, attend a conference, there is nothing like the interaction with the practitioners who are so desperately looking for the magic that will make their program work, forgetting they are the magic. Meeting others struggling to make it happen is the most invigorating thing out there, many friendships will be struck and a ton of e-mail will follow. Good luck with your program.

effort—put in the hard work!! Put in the hard work!! There is nothing like hard work and hard knocks to teach you what works and what doesn’t.!! When you have a success or find or breakthrough there is nothing like it, you drop on to one knee and pump your fist and say “YES!!!!” with the biggest smile on your face ever, it was all worth it and you walk a little taller that day. In the maintenance and reliability world, there is no silver bullet!! Everyone is looking for it, everyone hopes it is at the next conference or webinar or with the next consultant or with the new CMMS system. When it doesn’t happen, interest is lost, everyone hangs their head, walking away from the best thing that could happen to their maintenance program, reliability. Reliability in the process of work order planning and implementing, reliability in the process where diligent execution makes a find which saves downtime and a lot of money, reliability in the equipment operations relies on every day while they are running and most importantly reliably saving money. Everyone looks for the magic of that silver bullet. Everyone thinks, if only we could find the silver bullet the world will be all right. Well I have news for you, you are the magic, you are the silver bullet. Your determination to do things in a better way will drive a program to places you would never have dreamed of. Granted you need support for equipment and permission to go to some training courses. There is one component everyone seems to want to avoid, that’s
the hard work, they want quick fixes for everything that is not right in their program. Hard work and diligence is what gets it done, everything you put in to your program today will reap rewards in the future that you cannot imagine, there is a lot of money to be saved out there. Sure there will be mistakes made, something we seem to be averse to, in the long run your technicians are better and more confident for their mistakes, look at the winners of the program of the year or other awards, everyday people getting it done, making the magic happen. Be the magic your program needs!! Good luck with your program. Geoff Generalovic has been a maintenance electrician for 37 years.

execution Success in improving asset performance is not in the blinding brilliance of your strategy, but rather it is in its execution. It is important to work efficiently and make sure you are squeezing every ounce of productivity from your team. It is equally important and oft not focused on as much, to ensure YOU have your team DOING THE RIGHT WORK. Make sure you understand not only what is on the check sheets your folks are using to do their work, but WHY it is on there. There is so much great predictive technology in our space now that generates data that was never before available. I encourage you to make sure that the data that is being generated by the technology investments you have made, is integrated to your work management system. Technology that is not integrated to work management and planning and scheduling will not be executed on. Technology is being deployed in support of very well thought out and articulated strategy. Make sure you close the Strategy/Execution gap. Build strategy: • Identify technology/methodology gaps • Develop tactical work plan • Introduce analytic and sustaining technology • Execute the right work at the right time • Iterate
This year focus on your execution more than your strategy, once you are executing well, refine your strategy. Paul Marshall is the Chief Executive Officer of Ivara Corporation, the leading asset performance management software solution provider. www.ivara.com
expectations How many of us think we clearly define our expectations? I am sure most of us think that we are very clear in telling people what we want them to do. Rebuild that pump. Fix that mechanical seal. Eliminate that failure mechanism. Define the root cause. All of these are very concise, simple directives. They should all be easy to understand and execute in a reasonable timeframe. Ah, but have we clearly defined our expectations? When we make the assignment to rebuild the pump, did we define our expected results? Did we ask that they document the disassembly, clearly noting any exceptions? Did we identify how we wanted them to handle the exceptions? Is there a mechanism to document failure comments? Do they understand how it should be used? What content should be entered and in what format? Did we define the timeframe when we expect the job to be completed? When we ask to eliminate the failure mechanism do we provide a clear understanding of the parameters the employee must work within (e.g. budget and schedule)? Can the failure mechanism be eliminated by replacing the entire component regardless of cost or impact to schedule? That’s doubtful and is why expectations must be clearly defined. The examples could go on but hopefully the point is made that without clearly defined expectations, we will rarely get the results we desire from those that report to us. Make it a priority to define what you expect. With clearly defined expectations you will begin to instill a sense of accountability and ownership.

FRETT It would be fair to assume that the readers are reliability professionals. In that case Iâ€™m boldly proposing that they resolve, in the space of six months, to make an absolutely verifiable contribution to greater profitability of the enterprise with which they are associated. They can make this contribution if they unreservedly accept the fact that the basic agents of component failures are always Force, a Reactive Environment, Time and Temperature. Putting it in other words, whether the mechanical part is found in a gas turbine, a home sewing machine, or a reciprocating compressor is of no importance at all. Whatâ€™s important is that failure of the mechanical part is brought on by one or more of the failure agents we express with the acronym FRETT. To then achieve failure reductions and to eradicate repeat failures, a mechanistmaintenance technician must not just replace failed parts, but must authoritatively determine the contributing agent(s) of FRETT. The mid-level maintenance manager must actively support the endeavor by allocating the extra time needed to go beyond mere replacement of parts, and even the ranking top members of the organization must understand that beneficial change cannot result from business-as-usual attitudes, or without comprehending that targeted training is
cost-justified for all job functions. If with $500 worth of targeted training one avoids a $12,000 repair, there is absolutely no rationale for not implementing targeted training. Claiming that one cannot afford the required training because the economy is bad is preposterous, foolhardy, and unworthy of further debate. It is true, however, that all cogs in the reliability improvement wheel must be engaged; which is to say that all job functions have to buy into the simple FRETT concept if progress is to be made.

fundamentals One of the most important and most often overlooked areas of maintenance and reliability improvement lies in the fundamentals. Many of the facilities that I visit are caught in a game of chase, following whatever new philosophy or acronym has become vogue (I like to call it “chasing the shiny stuff.”). But fighting the urge and putting the “shiny stuff ” on the back burner is the basis of good maintenance. You must first take a look at basic maintenance practices and see where you stack up. Does your facility have a good partnership between maintenance and operations? Do you practice precision maintenance techniques? Are you capturing and using your maintenance history? Are your preventive maintenance tasks failure mode based and are they in use by your crafts? Do you truly plan your work? These and many other basic questions need to be addressed in order to build the foundation that will support true manufacturing excellence. Once these elements are shored up and strong, then the advanced tools and shiny processes will work more effectively to provide the most fundamental reason for manufacturing… profits.

grease We all know about oil analysis and the many benefits that this important technology has brought to operators of all manner of oil lubricated machinery. When combined with other key diagnostic technologies like vibration, infrared and ultrasound, the insight into the operating condition of an oil lubricated component can allow us to make the optimal decisions for operations and maintenance. But what happens when the critical component is grease lubricated? More often than not, we end up with a machine that has one fewer diagnostic tool at our disposal. In some cases, this isnâ€™t that big of a deal, but in others, the missing lubricant info can result in recurring failures as we fail to identify root-causes. In other cases, we are forced to allow the degradation of the machine to progress to the point where irreversible damage has occurred, before the signs of that damage are seen by ultrasound, vibration, or other indications. How much more effective could our diagnostic programs be if we could identify lubricant conditions prior to damage, and correct them pro actively. It happens all the time in oil analysis. For example, when we see high particulate count in an oil reservoir, we may employ supplemental filtration or more effective reservoir breathers to eliminate the abrasive contaminants before they can cause bearing or valve damage. The same type of concerns exist with greases, not only including the presence of particulate contaminants, but also mixing of incompatible greases, changes in grease consistency and other conditions that lead to later machine damage. By focusing on identifying these conditions as they develop, we can reduce or eliminate the component damage and improve equipment reliability. Also, when we know what caused the failure or the condition that could potentially lead to failure, we can address systemic issues such as grease mixing, contaminated bulk grease supplies, or equipment specific operating conditions that require re-evaluating grease types, additives or re lubrication methods or frequencies and quantities. The time is right to consider some of the recent advances in grease sampling and analysis that will allow us to include lubricant analysis for all our critical machinery, not just the ones that happen to be oil lubricated. Excellent research
is ongoing and has demonstrate the capabilities of rheometry in looking for changes in flow characteristics of grease, that can lead to thickening or thinning of greases in service, including conditions that lead to â€œtunnelingâ€?, or softening and loss of base oil from grease, resulting in ineffective lubrication. Sampling advances have opened the doors for trendable analysis of grease lubricated motors, pillow block bearings, gearboxes and other critical components. And other streamlined analysis methods like Die Extrusion can quickly and effectively trend changes in in-service grease condition to address Wear, Consistency, Contamination and Oxidation Conditions.

interrelationships Maintenance excellence is achieved by understanding and balancing the interrelationships between multiple facets of asset management. If a single dimension is omitted risk will be introduced, it may not be risk of equipment failure it may be financial (ROI) or process related. Reliability improvements tend to focus on equipment failures which lead to partial success of a single dimension of asset management.
This would signify the requirement for commissioning and startup procedures ether from the quality assurance perspective or if it was compliance issue, quality control. The facts supporting this conclusion are that abnormal failures should not happen and by happing in the Infant stage they should have been considered and mitigated though commissioning practices. Optimal loading and normal operation negate any operational issues.
The key relationships are identified by understanding: 1. Failure group:Â Equipment, Process or Business process. 2. Failure Type: Normal, Abnormal, or Random. 3. Life Cycle Stage: Infant, Constant or End of life. 4. Operational loading: Under loading, Optimal loading or Overloading. 5. Operational Stage:Â Startup, Operating, or Shutdown.
Example 2:Â During a major shutdown work information is lost for several contractor jobs.
By clearly understanding and identifying each item of a failure the correct mitigating action will become evident. There are individual solutions for each sequence if identifying words. All five items may not be applicable, but should be considered in all cases. Example 1: A hydraulic unit fails by contamination jamming servo spools on initial startup. Equipment Failure, Abnormal Type, Infant, Optimal loading and Operating.
Business process, Normal, Constant, Overloading, Shutdown. The fact that this is a situation outside of normal business process (high volume of work, shutdown) and normal (work information is normally lost during shutdowns) would drive the creation of shutdown business process mapping. This concept has been developed by Reliability Laboratory and is incorporated within a logic driven rule set. www.reliabilitylaboratory.com
I–P–F The installation to potential failure to functional failure (i–p–f) curve shows the value of precision maintenance. Most reliability experts agree that the first best chance to have reliable systems occurs during the design and installation phase of equipment’s life. Many organizations have been successful at managing failures using condition monitoring methods and managing to the ‘p’ of the ‘p–f ’ interval. At the end of the day, condition monitoring is still a form of reactive maintenance. We are detecting potential failures and reacting to them so that we can reduce the number of functional failures. What if we pro actively eliminate failures by ensuring that well-designed equipment is installed, commissioned, and operated so that the ‘p’ point is pushed as far to the right as possible?

journey Reliability is a journey powered by the innovations and diligence of the workers. Leadership acknowledges defect elimination is the key to reliability. Everyone is needed to eliminate 70 to 80% of the defects. Defect elimination through the use of cross functional Action Teams. Continuous Improvement Forums to acknowledge successes and bestow accolades. Empowerment of employees to continue to work cross functionally as they see fit to accomplish their tasks.
Leadership is passed on to the workers who now own the process.

light bulb I have fond remembrances, early in my career as a Reliability Professional, of when I made my first “call” (diagnosis) on a particular piece of rotating equipment that was in early stage failure mode. It doesn’t matter now who the Client was… but I realized then the power that I held in my hands. It was a little exhilarating to know that I was so empowered to help resolve productivity loss issues, help maintain my assigned assets and to help my organization manage and save money which conversely would help everyone within the Company. Later that year, while participating in a brainstorming activity to help resolve another tough equipment failure issue, I told one of my superiors that it was my job function to “help make you look good!” Facing these tough economic times and the problems and challenges that surround each inherently complex and diverse organization, I have always remembered that feeling and have tried to use that energy in all my efforts helping clients and customers solve their Maintenance and Reliability challenges. While researching a particular topic, I found the following Latin translation. “Condemnant quod non intellegunt.” Translated into modern English this phrase means “Those who do not understand… condemn.” In all my travels, I have always tried to teach, share, educate, learn, participate and generally foster a positive and proactive learning environment that surrounds the Maintenance and Reliability philosophy and how it can help you in your personal and professional life. Jim Disney has been a practitioner of Inspection, Maintenance and Reliability for over 25 years.

lubricants In December 2009, the maintenance manager of a small process plant made a rather strange statement regarding synthetic lubricants. He stated there’s not enough difference between mineral oils and synthetics to warrant his going with anyone other than the lowest cost supplier. Chances are, if his silly opinion prevails, he can soon take credit for the demise of his place of employment.
Anyway, while the full conversion of one’s lubrication strategy from mineral oil to synthetic lubricants might be difficult to cost-justify in every case, we know of instances where the use of expertly formulated synthetic lubes was easily justified. Two such instances are cooling tower fan gears and the bearing housings of centrifugal pumps where repeat bearings have occurred, or pumps where rising vibration and/or temperatures mandated countermeasures without shutting down the process. A tenacious synthetic oil film with improved film strength (compared to mineral oil) will cause gears to operate substantially cooler. In pump bearings on the verge of failure, a tenacious high-strength synthetic oil film will greatly reduce the risk of metal-to-metal contact of bearing components. There have been numerous instances of bearing vibrations and temperatures being substantially reduced, when compared to continued operation with mineral oils. In these “bad actor” pump bearings, an appropriate synthetic is thought to fill the microcracks in a manner that cannot be matched by mineral oils. Of course, it will make even more economic sense to keep the synthetic oil clean. Moisture and dirt can largely be excluded with good bearing protector seals; moreover, oil change or oil replacement frequencies can typically be extended four to six-fold with synthetics. It will be worth noting the various generic styles of rotating labyrinth seals being marketed today (see figure on left). Figure: Generic bearing housing protector seals with configurations that risk O-ring degradation (top left) due to contact with sharp grooves; a configuration that uses a V-contoured ring (top right) tending to increase frictional drag; and a modern design (bottom) with optimally placed O-ring locations.

get connected! Maintenance and reliability professionals can feel isolated, particularly if working in asset management in a site remote from contact with like-minded people. This can also happen in a small workplace without the contact with fellow professionals that is so important in sharing ideas and talking through proposals. Such isolation can also mean that continuing education opportunities are harder to find. Ray’s solution? I have thought on this over my 45 years as an engineer. First… join whatever professional organization is available and take advantage of its networking opportunities. SMRP, PEMAC, AMC, AMP are examples. Attend their meetings and conferences (heck, even offer to speak) and use their on-line forums. Second… widen your views by regular reading of available journals. Many are available online. Third… undertake formal studies. Some universities offer distance learning programs that lead to a formal qualification, up to Master’s degree. (Conditional entry is often available for those who do not hold a bachelor’s degree). Many students well-experienced in asset management have told me that their studies have widened their views and helped their work performance, Ray Beebe joined Monash University at its rural campus in Australia in 1992. He has led its off-campus postgraduate programs in maintenance and reliability engineering since 1996, with students around the world.

The loss of US manufacturing has been staggering in recent years with some industries all but disappearing. Let us turn the tides in 2010 using the â€œAmerican ingenuityâ€? that first sent the US to the forefront of the manufacturing revolution. It is what separates us from our competitors. What can we do differently? How can we create products that are better than any competitors? What challenges can we overcome? What waste can we remove? We can produce goods competitively but it will not be the way our predecessors did it. What changes will you start today?

Networking, Not Working Here are a couple of questions and ideas about networking: • What do you want from your network? • What are you prepared to put in so that others can benefit from your contributions? If either of those questions was easy to answer maybe you might want to stop, go back and take another look! It may be that when you think of your professional network that it seems to be simply a place where you can try to find an answer to a technical work issue that you’re stuck on. OK, there’s nothing wrong with that and most of us do it from time to time. Try thinking about it from a different angle when you simply take from a network a couple of things happen. The first is that it is essentially selfish to do that and second is that it deprives others from the chance to benefit from you. So, the real question here is are you
being selfish or are you simply afraid that you could seem foolish when others read your contributions? If you have a couple of minutes to be honest with yourself you might see things a little differently (or not). The second question is all about what you are prepared to put in to give a little more freely without the expectation that ‘there’s something in it for me’. What’s in it for you is knowledge that you’re freely and openly helping others, sharing your ideas and knowledge. So, my thoughts for 2010 revolve around moving forward, making just a little more time to actively contribute to the reliability / asset management community, discovering new friends to share ideas with. My hope for 2010 is that some of you might join me in this effort.

operation-ility Facility Reliability (FR) is the reliability of equipment throughout its entire lifecycle. It can be thought of as cradle to grave reliability. The simplest definition of reliability is “The probability that an item will perform its intended function for a specific interval under stated conditions.” What makes this definition context sensitive is the word “operating”. Plant managers want to operate is such a way to meet their quota. Operations managers want to use the equipment as much as possible. Design Engineers want equipment that operates to required capacity. In today’s manufacturing and production environment there are different perceptions of reliability. FOR is the ability to produce the required amount of product over a specified period of time. FR is influenced by design (or inherent) reliability (IR), procurement reliability (PR), installation reliability (InstR), operations reliability (OR), and maintenance reliability (MR). In the past these have been treated individually but not necessarily from a reliability perspective.
IR, PR, and InstR are related and can be viewed as the Initial reliability (InR). InR is a constant after start up. The combination of OR and MR is the ongoing reliability (OgR). OgR changes day-to-day. Therefore: FR=InR x OgR Where: IntR= PRxIR x InstR And OgR= OR x MR One metrics commonly used to measure a facilities performance is Overall Equipment Effectiveness (OEE). This is the product of availability, process rate, and quality. OEE can be viewed as a measure of FOR but the relationships between the two must be clearly understood. Of the three parts of OEE only availability is impacted by IntR. OgR has an impact on all three parts of OEE. Therefore, if a company wants to change OEE, they can change IntR, OgR, or both. Our industry must begin to think in terms of Facility Reliability as a whole entity.

operators Operator maintenance is often one of the largest missed opportunities in capital intensive industries. Our research shows that progressive companies use operators for between 50% and 75% of their predictive and preventive work by man-hours. The large number of man-hours accumulates because operator maintenance is frequent (every hour or every shift) compared to mechanical or electrical maintenance. Can you afford not to take advantage of operators and increase your effective resources by 30% or more?
Here is one way to go about this: Become a believer that maintenance is a process and not a department. This means that all inspections, tests and programmed component change outs, whether they be operator executed or not should be derived from the one process and method. Engage the production people in this concept. Ensure the production people see this as a benefit to them by explaining that you could use your scarce technical resources to add greater value if the operators were provided good instructions and were completing a many of the frequent maintenance tasks. Select a machine or system and sit down with the mechanical and electrical people and the operators and work through the current maintenance program and failure modes on the equipment to develop firstly, a new operator maintenance check sheet, and secondly a target operator maintenance check sheet. The target is used because it is likely that there will be some tasks that operators could do with the benefit of some training. The “ready to go” changes should be implemented immediately. The “need some training” changes can be introduced as the training is completed. Steve Turner founded OMCS International in 1996.

performance On the subject of machines, “Performance” is the most important single word to the reliability, maintenance, engineering or operations professional. A machine’s performance goal is to maximize its productivity while minimizing its cost of operating and ownership over its life cycle. Machines that perform well share common characteristics while machines that routinely fail share a different list of characteristics. Machines that perform to their expectation are: • Well lubricated • Clean • Well lit when required • Safe to work on and around • Inspected routinely • Installed accurately and correctly • Productive In addition, these machines have a management program which includes: • Measurement and reporting of their productive performance • Regular inspection using appropriate technologies • The criticality of the machine within its process is well understood • Easily accessible maintenance information • Query-ability of maintenance and performance data The machine can be compared with other machines of a similar nature within a common data management software. The machine might have been evaluated by RAM, RCM, FMEA or FMECA study during its lifetime.
The machine is identified at birth and is managed through to its death. The machine meets its quality requirements. Globally we lack statistics that would accurately verify that these characteristics contribute to the productive performance of machines… but we know that they do. Achieving the performance expectation of machines is simple. If it seems complicated within your operation, then take a close look at your activities and ask a basic question... “does this activity contribute to the productive performance of my machine”.... and if the answer is no, then reconsider why you are doing the activity.

planning Planning is normally thought of as the preparatory work before crafts persons start work. Such advance planning should save time later during execution of the work. Yet, in actual practice, new planners at first do not plan future work. They spend most of their time “chasing parts,” i.e., helping crafts persons find parts for jobs already in-progress. Curve A shows this initial planning effect as first a dip as the plant takes good crafts persons from the workforce to become planners. The curve then rises as the planners become “Go-To” persons for quickly using the CMMS, equipment manuals, inventory systems, and purchasing processes. This interference with planning sufficiently keeps planners from planning enough unassigned work. Curve A finally plateaus or falls as chasing parts can only improve overall maintenance effectiveness so far. Curve B shows management actively redirecting the workforce not to interfere with planners and shutting down the parts chasing. Planners now plan enough work not yet assigned so that the weekly scheduling can select jobs with estimated skill and labor hours. The weekly goal setting against available crew hours greatly improves productivity enough to raise overall maintenance effectiveness. Curve C shows advance preparatory work finally increasing maintenance effectiveness. Yet, this increase is mostly possible because planners (still being protected from chasing parts) use a Deming cycle of improvement. They use feedback from previous work and avoid planning each job from scratch. Curve D finally shows the final frontier for maintenance planners and effectiveness improvement. The planners collect and file work orders with appropriate codes and information. So equipped, plant engineers make better informed decisions about equipment refurbishments and focus on the proper plant improvement areas.

PM Review Our research shows that most maintenance programs have holes in them and often there is no effort made to change the situation. Sometimes, the opposite is the case. Every time a failure occurs, the maintenance manager creates a new task. Best practice organizations understand that it is not practical nor economical to try and prevent or predict every failure. The flow chart helps organizations deal with failures caused by lack of maintenance. Warning! Most organizations are already trying to do too much maintenance. The application of this flow chart will only add to the problem if there are insufficient resources to complete the current one. Before this flow chart is implemented, we recommend you run a PM Optimization or Review program on the assets to reduce the PM requirement first and up front, eliminate maintenance that is not cost effective or duplicated. The starting point [F] is any unplanned failure that has occurred in the plant. The first step is to define the failure mode or mechanism of failure. Following this [Failure Analyzed?], it needs to be determined if this failure mode has been analyzed previously using RCM/PMO logic or is supposed to be covered by the existing maintenance program (donâ€™t forget to consider operator maintenance).
If it has not [N], then it should be put through an RCM/PMO analysis [Apply RCM/PMO]. If it has been reviewed [Y], then the validity of the previous review needs to be assessed against the fact that the failure has now occurred unexpectedly [Failure Prevented?]. The previous analysis may have recommended a â€œNo Scheduled Maintenanceâ€? policy in which case, the outcome was expected and no further action need be taken except if the failure has now become more of a problem than originally thought [Increasing problem?]. Then modifications and a revision of the RCM/PMO should be undertaken based on the decreased reliability. If, however, the recommendation was for PM and the PM has failed [System Downfall], then the source of the problem needs to be identified and rectification action taken. Note that when organizations commence this type of process, they document the failure modes of the system or equipment that maintenance is covering. This list makes the flow chart easy to complete. Trying to implement this system without the failure mode list requires a lot of searching through PMs and work instructions. Steve Turner founded OMCS International in 1996.

regreasing High quality machine re lubrication is a vital component of machine health and productivity. There are many areas to consider when making a quality improvement plan, including lubricant selection, storage and handling, re lubrication intervals, contamination control, lubricant analysis for effective planning. While grease purchases comprise only about 5% of the lubricant budget, grease re lubrication occupies the majority of the lubrication technician’s time. Most plant grease application intervals are based on speculation rather than facts and operating conditions. Grease intervals can, and should, be calculated. Influences include bearing type and size, shaft speed, operating conditions (vibration, heat, moisture, atmospheric debris, shaft orientation). AMRRI provides a formula that is a modified version of a FAG bearings company formula, as follows: t = K * [[(14*10^6) / (n*(d^1/2))] – 4*d] Where: t = time in hours until next re lubrication event K = product of all correction factors (Ft*Fc*Fm*Fv*Fp*Fd) n = RPM d = bore diameter (mm) F = correction factors (see table)
The operational factors (F values) are: Condition Temperature Ft Contamination Fc Moisture Fm Vibration Fv Position Fp Bearing Design Fd
Average Operating Range Housing below 150 F 150 to 175 F 175 to 200 F Above 200 F Light, non-abrasive dust Heavy, non-abrasive dust Light, abrasive dust Heavy, abrasive dust Humidity mostly below 80% Humidity between 80 and 90% Occasional condensation Occasional water on housing Less than 0.2 ips velocity, peak 0.2 to 0.4 ips Above 0.4 Horizontal bore centerline 45 degree bore centerline Vertical centerline Ball Bearings Cylindrical and needle roller bearings Tapered and spherical roller bearings
Correction Factor 1.0 0.5 0.2 0.1 1.0 0.7 0.4 0.2 1.0 0.7 0.4 0.1 1.0 0.6 0.3 1.0 0.5 0.3 10 5.0 1.0
An example of the product of this approach is displayed to the side for ball bearings at 3.5 and 4.5 inches bore diameter, and several speeds. These results are in DAYS between re lubrication events. A pinwheel interval selector for common bearing types is available from AMRRI at www.precisionlubrication. com/tools. Mike Johnson is the owner and principal consultant at AMRRI.

REVIEW From a PdM standpoint whether you have a well established program or just starting one, they are always in need of review. If you have an established oil analysis program when were the slates of analysis parameters set up for your equipment. Have there been new tests established, or are there additional tests you learned about over the year that might be helpful in catching information about the lubricant or the equipment. Are you utilizing the analysis report information to the fullest extent to allow extended oil changes, changing filters only when needed, upgrading filters and breathers? All of the information you need is right there in your analysis report, you just need to review it and utilize it! When was the last time you looked at your vibration spectrum parameters, or reviewed or set up fault frequencies for the components of the equipment? Do your spectrums have enough range to include everything that is going on in that equipment train, or are you collecting more information than you need? Has the equipment been replaced by something similar but different when it comes to meaningful vibration data collection. Does it provide you with specific information on the internals of the equipment or just overall vibration amplitudes? When was the last time that alarm settings were modified or changed? If there is a lot of equipment in alarm condition, is it really a problem or just incorrectly set alarm limits. Maybe itâ€™s not within industry standards but it is the best it can be for what it is and the conditions it is running in. You have several years of data and no unexpected failures on this equipment so why not adjust your alarms to reflect your equipment history. So why not take a few minutes and make some adjustments. Tweak some alarms, add some new or different tests, and make sure you are getting the correct and needed information to keep your program alive and growing. Why not make it a point to review and update as needed! Brian Thorp is a 35 year plus veteran to maintenance. His last 25 years have been in power generation with the last 10 years as a lubrication specialist. He holds the CLS and MLA II certifications among many others in the predictive maintenance field.

status quo Short for “status quo ante bellum” meaning “the state before the war.” Used to reinstate property boundaries, ownership, etc after a nation is defeated. As we move into 2010, many of us have been defeated by moving from one initiative to another without fully ever reaching our potential in the previous initiative. All too often we are caught up in the day-to-day fight within our organizational culture to keep the operation moving in the right direction. Many times that comes at the expense of our maintenance and reliability efforts. As we look forward to the New Year, I offer you this challenge to identify the pockets of excellence within your organizations whatever they may be and to build upon them. Before attempting to take these areas to a new level, first identify where you want them to be at the end of the year. Develop your plan, set your milestones and measure your performance along the way. This will assist you in attaining your goals. If you do stumble along the way, learn from it and apply what you’ve learn to improve the processes. In great attempts, it is even glorious to fail. When you start building on the pockets of excellence in your organization you can start to link them together. By doing this, you now move from pockets to sustainable areas of excellence within organizational culture. Shortly after
taking the helm of the Green Bay Packers legendary and hall-of-famer coach, Vince Lombardi, said to his players “men we will strive for perfection fully knowing we will never attain it, because nothing in life is perfect, but along the way we will find perfection and perfection we will have”.

steel â€œAs steel sharpens steel, so one man sharpens anotherâ€? With every passing year, more and more good steel retires from the workforce. The best way to address the gap in skilled labor is to ensure knowledge wrought from years of experience is captured and used to improve the work force that will be left in place. Mentoring colleagues, developing procedures and processes, capturing work order history, refining preventive maintenance documentation, and participating in Reliability Centered Maintenance efforts can help us sharpen our steel with steel in 2010. Steel thatâ€™s not used rusts, and rusted steel benefits no one.

SURVIVAL To remain competitive and economically viable within today’s industrial world of cost cutting, downsizing and global competition, many anxious and distressed companies are searching “again” at improvements within the maintenance departments. Whether implementing a new CMMS, investing in new Predictive (PdM) technologies or the latest buzz trend, these all remain nothing more than a fine tuning of the status quo! Most North America’s industrialized production facilities still struggle to effectively change from the continuous fire fighting maintenance, unacceptable equipment reliability and the associated ballooning operating costs. This is after decades of promoting and implementing continuous changes in the maintenance programs, advanced diagnostic technologies, and huge investments in both manpower and financial support. One constant over the decades is the departmental structure of Production/Operations, Engineering, Maintenance, Procurement, Health and Safety, and Environmental departments within most of these facilities. These departmental silos inherently protect the expertise of the people working within each silo while also isolating the people working inside the other silos. The end result is empowered departments with individual goals, objectives and budgets. History has taught us that true change requires a revolution or transformation of complex systems or organizations by a radical change or complete replacement of the former way of thinking. With the present global recession, competitive markets, mergers and/or looming plant foreclosures, it is time for change. Time for a paradigm shift to breakdown traditional departmental fiefdoms or silos
and re-align the organization into one unified goal of improving the plant’s equipment reliability and performance while effectively reducing operational costs. Operational Excellence (OE) is keyed term for a philosophy of unified leadership, unified team work and unified problem solving resulting in continuous improvement throughout the organization. By having “only” company wide goals and budgets, empowering employees and optimizing existing activities in the process, every individual in the organization is made accountable. Accountable to not only improving equipment reliability but also the entire business effectiveness including improving risk-safety, environmental integrity, energy efficiency, product quality, and customer service to mention a few. OE stresses the need to continually improve by promoting a stronger teamwork atmosphere, common goals and plant wide accountability.

One of the key markers of success in 2010 will be an organization’s ability to sustain beneficial change. When we deconstruct sustainable change we are left with five key areas: • Leadership: know what to change and when to change (your leadership style and your processes). • Communication: understand what medias to use, how to use them and at what frequency. • Change Dynamics: know what to expect when those affected by the change start the process. • Risk Identification: understand what could go wrong and what you are going to do about it pro actively. • Project Management: know who is going to do which step and when, during the implementation of the change. The battle to insure that your organization understands and applies each of these is the challenge you face. When these areas have been addressed with your change strategies, you’ll be well on your way to a successful 2010.

SWAPPING A maintenance practices manual segment on â€œproven best practices for spare pump operationâ€? notes that the more frequently a pump is started, the lower its anticipated Mean Time Between Repairs (MTBR). It correctly explains start-stop transients as stressing pump seals and bearings. Accordingly, the manual advocates a criticality ranking of all pumps into four categories and then alternating operation (swapping) on the following schedule: Emergency: Every 4 weeks Normal: Every 52 weeks Vital: Every 12 weeks Low: Never This approach does not follow logic; for the most critical equipment the owners apply the strategy that, in their words, will give them the shortest MTBR. Indeed, the manual seems to have overlooked that few pumps will run flawlessly after sitting idle for 52 weeks. After a year its bearings will have degraded for two reasons: One is micro-vibration transmitted from adjacent running equipment; that vibratory motion causes the oil film to be wiped off. The result is metal-to-metal contact and false brinelling, usually at the lowermost bearing balls. The second typical result is corrosive damage unless dry sump oil mist is used. Swapping every 6 to 8 weeks makes the most sense; it will protect the bearings and will keep the product in piping and seal regions from partially vaporizing. Swapping will also serve as a training exercise to keep operators sharp and alert. Keep it up. Heinz P. Bloch holds BSME and MSME degrees from the New Jersey Institute of Technology.

systems Why is it that great ideas improve your maintenance, but reliability processes fall apart not long after implementation? Often you will see excellent compliance while the situation is being monitored, but after that things slowly move back to the old ways. The answer is that the system, process or practice has never become part of the culture. So how do you embed changes into your culture? Ultimately for people to accept change they need to value it. I call this the “What’s in it for me” syndrome. To value a change, people affected have to have a very clear understanding of the reasons behind the change and the outcomes expected. They also need to have a robust system put in place so there is no ambiguity as to what the change entails. When people value the change and have a robust system in place, the process can be embedded into the culture. A good example of this would be building PM’s into your CMMS. Most people will understand the benefit, it will provide them meaning full work, and because it is systemized via the CMMS is likely to still be operating for many years to come. What do you do if people still don’t see “What’s in it for them”, but the changes have to be implemented for other reasons? In this case where you have not won people over, you still must build a robust system and ensure people follow it. In time, the benefits may become more obvious, but ultimately continued compliance will eventually lead to a cultural change. The common denominator here is that you must have Robust Systems and then ensure compliance to ensure cultural change.

TEN THOUGHTS FOR 2010 If 50 years of engineering of which 20 dealing with reliability gave me any valuable insight, here goes ten thoughts (while not new ideas, it may be a useful summary update for successful action—they are in no priority sequence and, of course, there may be more). 1. SIMPLE vs. COMPLEX Keep it simple! “Simple is beautiful” (quote from Story Musgrave, astronaut) 2. THEORY + PRAXIS Don’t attempt practical implementation if it is not based on a sound and proven theory. You must introduce theory. Without theory it will never work. BUT: theory alone will not get you there! You MUST turn theory into practical implementation. 3. RELIABILITY BEYOND MAINTENANCE Reliability is no more RCM alone. Just as “quality” had turned into “TOTAL QUALITY”, now RELIABILITY has expanded to also cover Operations and more… OVERALL RELIABILITY. 4. NOT ONLY PHYSICAL ASSETS Precisely because we need to concentrate on Physical Assets, we must explicitly consider the LINKS these assets have with the other assets: HUMAN Assets, FINANCIAL Assets, INTANGIBLE Assets and INFORMATION Assets. PAS 55 clearly explains these links. 5. CULTURAL CHANGE No implementation can succeed without the accompanying Change Management. This has to be built into the implementation, not as an “add-on” but as an integral part of it. 6. MANAGEMENT SUPPORT A requisite, without further comment…
7. A CHAMPION For success and sustain ability you must appoint a “Champion”. 8. ALIGNMENT Goals must be aligned. Each specific goal must address the Company Business Goals and values. 9. MEASUREMENT “If it can’t be measured, it can’t be managed” Make sure your KPIs are FEW, correct, valid, understood. 10. PERSEVERANCE FOR SUSTAIN ABILITY If problems strike, face them and solve them. Never give up. Henry Ellmann is Founder and Chairman of Ellmann, Sueiro y Asociados, Management and Industrial Engineering Consultants, Europe and America, since 1958. Born in Vienna, Austria, 1933.

The Rules There are some things that are consistent throughout any industry. Let’s call them ‘the rules’. They are almost universal in their application, with only slight variations from place to place. You can try, but I don’t think there is any way to avoid them entirely. Rule One: Stuff that hits the fan is not distributed evenly. When the stuff hits the fan, it tends to affect everybody in the room, not just those who caused the stuff or turned on the fan in the first place. If you are in the room, you will be hit by some stuff, and by no means will it be in proportion to your personal level of involvement. Fair? Of course it isn’t fair. Check your job description. I doubt you will find the word ‘fair’ in it anywhere. The real tragedy here is that in a lot of cases—I would almost go so far as to say most cases—the innocent are punished and the guilty go virtually unscathed. The ‘fan’ is more like a shotgun than a sniper rifle. If you had nothing to do with the event but are in the room and got hit by the stuff anyway, it is just the price you pay for being in the room. The real rule here is don’t even be in building – let alone in the room – when the stuff hits the fan. Rule Two: Eagles soar, but weasels don’t get sucked into jets. If you absolutely must be in the building when the stuff hits the fan, being a small target is a good thing. Being a small target hiding behind a bigger target is even better. Logic dictates, though, that a large target hiding behind a smaller target not only isn’t very effective, but it casts some serious doubt on the intelligence of the large target. Although being an eagle is cool, but there are also advantages to being a weasel. Rule Three: If you can’t stand the heat, don’t tickle the dragon. Consider the consequences of your action before you take the action. This is especially true in a ‘management by crisis’ environment. Sometimes the medicine is worse than the cure. Sometimes that ‘knee jerk’ gets a little extreme and ends up kicking someone in the teeth. Think before acting. Try to determine what could possibly go wrong, and see
if you can come up with mitigation for whatever it might be. Being proactive is great, but you still have to look at all sides of the equation. Rule Four: Never challenge worse. Never, ever, utter the words “It can’t get any worse than this”. If you tell a mechanic “It can’t be done”, it will be accepted as a personal challenge. If you say “It can’t get any worse than this”, “Worse” will take it as a personal challenge and SHOW you that yes, it can get worse. Rule Five: Just because you’re different, doesn’t mean you are useful. I worked for a manager once that would not—could not—admit he was wrong. Ever. It was like the word ‘wrong’ wasn’t even in his vocabulary in relation to himself, but somehow he managed to say it frequently to others around him. If he got pushed to the limit on something that he was clearly wrong about, he would resort to his favorite saying, “It’s not wrong, it’s just different.” ‘Different’ and ‘wrong’ are not mutually exclusive terms. You can be either, neither, or both. Rule Six: All things—either good or bad—will get worse if left unattended. This is a basic concept that any technical minded person understands. It is also the entire reason that your preventive maintenance programs and reliability programs exist. Yes, you can get away with not changing the oil… for a while. Maybe even for a long while, but eventually it will catch up to you. This concept applies to programs, processes, people, and systems as well as to mechanical things. Rule Seven: Two out of three ain’t bad. Cheap. Fast. Good. Pick any two. Yes, this applies to your plan. You can have cheap and fast, but it won’t be good. You can have fast and good, but it won’t be cheap. You can have cheap and good, but it won’t be fast. You can occasionally get ‘kinda cheap, kinda fast, and kinda good’, but that is just a compromise, and all three parts of the triangle suffer. All you can really do is decide which two you want and go for them.
The Rules (cont.) Rule Eight: Stuff rolls downhill. Stuff rolls downhill. It is a natural law of physics that stuff starts at the top and goes to the bottom. This is one of the many reasons why being at the bottom is not really great. You catch all the stuff coming down from above. But being in the middle isn’t so great, either, because while you catch all the stuff on the way down and pass it on, some portion of the stuff that hits bottom bounces right back up to you, so, in reality, you catch stuff from both directions. In that sense, it is almost better to be on the bottom, because you are only hit from one direction. Rule Nine: What you get done is more important than what you do. There is an old saying that goes “If you can’t produce results, show furious activity’. It is possible to be busy—or, to look like you’re busy—all day and accomplish nothing, or at best, accomplish nothing of value. Results count more than effort.

Unacceptable Nearly everyone agrees that failure is unacceptable. What we can’t seem to agree on is what a failure is. The best definition of failure I have read was developed by the Nowlan and Heap led team that made up Maintenance Steering Group 1 (MSG1) over thirty years ago. The seminal work they did eventually became the backbone for reliability-centered maintenance. The team came up with the following definitions for failure and the two primary failure types. 1. Failure = “The presence of an unacceptable condition” 2. Potential Failure = “An identifiable physical condition which indicates a functional failure is imminent.” 3. Functional Failure = “The inability of an item, or equipment containing the item to perform to a specified performance standard.” The definitions of potential failure and functional failure led to the development of what we commonly call the ‘p’ to ‘f ’ or ‘p-f ’ interval. Defining failure as the presence of an unacceptable condition makes it possible for an organization to define failure in its own terms. Reactive organizations are willing to accept any condition up to functional failure as an acceptable condition. Highly proactive organizations are successful because their definition of an unacceptable condition is when a potential failure has been detected. We like to call it managing to the p of the ‘i-p-f ’ curve where ‘i’ is installation, ‘p’ is potential failure, and ‘f ’ is functional failure. Accepting Potential Failure as the actual point of failure changes the entire way we manage maintenance activities, and makes it much more likely that we will try to find the root causes of the potential failures, eliminate them, and create a more reliable operation.

upgrade So how long have you been pulling oil samples by sticking a piece of tubing into a reservoir or snaking it down into a motor bearing cavity. You may be getting a sample for analysis but is it a truly representative sample. Sample fittings are the way to go for a consistent, representative, sample when installed correctly. There are several manufacturers such as Checkfluid, Donaldson, Minimess, and Trico, to mention a few, that supply these fittings in various configurations to meet just about any application. These companies usually have proper installation information on their web sites to help you to get them in the right place. There are also several articles written on the proper placement of sample fittings. Another major added benefit to utilizing sample fittings is saving time when collecting your routes. On average you can cut your collection time by 50% or more. When collecting your vibration routes, are you still hunting a flat, smooth, surface to put the accelerometer magnet on? On some equipment finding a good spot can be challenging to say the least and if you donâ€™t have a good surface your readings can be incorrect. Installing a target or pad can provide a good consistent surface for the accelerometer magnet to mount. These are commercially available or can consist of magnetic stainless flat bar. They are either glued with a special epoxy or threaded to the surface of the equipment in the correct axis and provide a trouble free surface to stick your accelerometer on. This not only reduces your collection time, but increases your collection quality by providing a predetermined proper surface for your collection points. The last and most costly upgrade would be the installation of IR windows. These allow you to look into your energized cabinets while reducing the exposure to flash created when a cabinet is opened for inspection. They also reduce the need to wear the cumbersome PPE required when opening an energized cabinet. The IR windows are available in different sizes, styles, and provide a membrane between you and the energized equipment that does not interfere with the IR camera.Â Brian Thorp is a 35 year plus veteran to maintenance.

visualization Many organizations have pieced together their functional programs; maintenance, engineering, procurement, marketing, etc. Over the years maintenance departments may have initiated a PM program, later they dabbled with predictive maintenance, RCM and LEAN in an ebb and flow manner. Success was mostly based on the personality of the person driving the initiative. When the driver moves on the program languishes, or evaporates. More often than not, organizations donâ€™t take the time to think about and institute a structure for how the various elements of organization fit together. When leaders and the workforce have a common understanding they can categorize where the activity fits in the big picture and can take appropriate action. Visualization of a model helps people to know where day-to-day activities (Control & Stability Realm) and continuous improvement (Proactive Reliability Realm) activities fit in the big picture. The Control & Stability Realm contains Foundation, Processes and Focus & Execution elements. Foundation elements refer to having the resources needed to carry out responsibilities; adequate budget, software, organizational structure, tools, facilities, etc. Processes are the organized activities that allow people to perform their functions consistently; work management, inventory management, etc. Focus & execution is correlated with leadership and management; providing guidance and support to people and processes. The Proactive Reliability Realm includes Reliability Improvement Prioritization (RIP), Reliability in Design (RID) and Reliability in Operation (RIO). RIP takes data generated from the Control & Stability Realm, organizes it and prioritizes improvement opportunities. RID is the application of tools to exploit opportunities (RCM, LEAN, Root Cause Analysis, etc.). RIO contains standards on how to perform activities; such as lubrication programs, predictive maintenance guidelines, operator performed maintenance standards, etc. Visualization of an Organizational Reliability structure should work for all functions in the organization. In this way, common approaches can be established.
A glossary of terms and manner of looking at challenges and opportunities can be developed. This allows organizations to develop a culture of Organizational Reliability; avoiding the ebb and flow of personality driven programs.

waste The single biggest barrier to identifying waste is called “the normalization of deviance.” This is a fancy way of saying that if you look at a pile of junk long enough, you’ll stop noticing it. The pile begins to seem normal. This tendency is the bane of PM inspection (when people stop seeing deterioration) and lean maintenance efforts (when people stop recognizing waste). Sometimes we have to shake up our normal methods of seeing. A great way is to visit other plants, even in other fields. You’ll be surprised how easy it is to identify other organization’s waste. This ability lasts a few days—then you will normalize their deviance. Other eye-openers: going on vacation, taking a seminar or class, enjoying a book or an audio. But make quick use of your altered sight. In a day or two, most go back to being blind to the waste. Another good approach is to start a new list. Example: list the top ten parts used by part number and usage. The waste is right there and can be seen by asking the five whys. Why do we use this part? When you get the answer to that question, ask why that happens. Repeat asking “why” another three times. In a few minutes you’ll get answers which can help reduce usage of many parts. Remember, for every part whose usage is reduced, you also reduce the labor and inventory costs associated with that part. This little trick can be repeated
with the new top ten. It is okay to skip a part that does not yield a solution in 30 minutes. Simply go to the next one. Don’t forget to have some fun with this method.
