MY TAKE
Jane Alexander, Editor-In-Chief
You Snooze, You Lose
T
his column goes to press on Election Day. By the time you read it, the voters will have spoken and scores will have been settled. Regardless of your leanings, you, like me, will probably be delighted the mid-term madness is finally over—and that maybe, just maybe, sanity and civility will return to the legislative process, and Washington will get down to the business of healing our economy. For now, I’ll keep chirping about innovation. In a column entitled “An X-Ray of Dysfunction”* (The New York Times, October 9, 2010), the great Thomas L. Friedman quoted the Wall Street Journal columnist Gerald Seib, who once noted that “America and its political leaders, after two decades of failing to come together to solve big problems, seem to have lost faith in their ability to do so. A political system that expects failure doesn’t try very hard to produce anything else.” Well said, Mr. Seib. As Friedman went on to assert, fortunately the expectation and production of “failure” hasn’t taken root everywhere in the U.S. While America may often seem to be paralyzed from the top down, he’s seen, for himself, that it’s alive from the bottom up: “The more I travel around our country,” he wrote, “the more I meet people who didn’t get the word that we’re supposed to be depressed and on our backs…” I’m with Tom. Although he specifically referenced “innovating with technology” as an example of what he’s been seeing, plenty of other types of innovation are paying off around the country. One place that immediately comes to mind is Arkansas-based Baldor Electric Co., where nobody appears to have been snoozing through the downturn—or gotten the word they’re supposed to be depressed and on their backs. I recently had the opportunity to tour the company’s big, beautiful, busybusybusy Fort Smith motor production facility, where three shifts a day, five days a week, are currently building 30,000 motors in the 1 - 15 hp range—per week. (And this is just one of several Baldor motor plants.) The number of offerings this company is producing and the way it’s delivering them to the marketplace represents an awesome undertaking. It’s clear that some real innovative thinking has been going on in Fort Smith. Based on its history, though, that’s not unusual for Baldor. (BTW: This site visit also reinforced the idea—at least for me—that reliability begets reliability. In Baldor’s case, its ability to supply reliable motors for your reliable operations depends, to some extent, on reliable processes that depend on reliable equipment, including—what else—reliable motors. It’s like looking at a reflection in a mirror…of a reflection in a mirror…of a reflection in a mirror… Where does it start and where does it end? Intriguing!) But back to the topic of innovation: It’s what has been keeping more than a few operations viable over the past couple of years, and will be just as crucial (if not more) in the future. That includes innovating in the areas of maintenance and reliability—something you’ll be reading a lot more about in this magazine. You really can’t afford to snooze. That’s all I’m going to say for now, though. Check in with me next month about what we have coming up for all you innovators out there! MT jalexander@atpnetwork.com

OEE And ‘Balls To The Wall’ We’re all in a race—a race to improve competitiveness. Our racecars and our plant’s equipment are sometimes running “balls to the wall” (so to speak), but we often lose sight of how well we’re doing with our maintenance and reliability programs. We can measure a lot of things, but does overall equipment effectiveness (OEE) truly indicate how well our equipment is performing? What first began as a very simple concept has morphed into one of today’s most misused and misunderstood equipment reliability metrics. OEE’s original intent involved measuring machine performance improvement over time by way of three data sets: Availability, Performance Efficiency and Rate of Quality. Seems straightforward enough. I’ve written about OEE several times in the past decade, but it bears repeating—especially after my last column on hidden losses (Uptime, October 2010). And there’s more to the story, too… In the early days of Total Productive Maintenance (TPM) in America (around 1986-1990), we learned TPM was about “improving equipment effectiveness.” In fact, the acronym “IEE” was floated among the early purveyors in this country. IEE (improving equipment effectiveness) didn’t stick: OEE did. Since then, these three vowels have led managers, consultants, authors, speakers and continuous-improvement experts down a road to mass confusion and disagreement. In case you haven’t noticed, we frequently have a tendency to confuse the original meanings and usefulness of lots of things. It seems to be especially true with acronyms—those shorthand abbreviations for a series of words that are meant to communicate a powerful concept. “Overall equipment effectiveness” has fallen prey to a fuzzy interpretation because the roots were severely pruned back, shortened and grafted into a new species of modern metrics. Interpreting ‘balls to the wall’ “Balls to the wall” has also fallen prey to fuzzy interpretation over the years. What does it really mean? If you’re guessing, you may be thinking it has something to do with “going flat out” in terms of speed or effort. You’re right. Sometimes, you might also hear “balls out” in reference to performance—much like 8|
MAINTENANCE TECHNOLOGY
Star Trek’s engineer Scotty telling Captain Kirk, “I’m giving you all she’s got down here.” These phrases seem to have originated around the following operations in the mid- to late-1700s: n Grain-grinding windmills controlled the space between the millstones with governors. n Governors limited the speed of water wheels. In 1788, James Watt applied the principle to control the speed of the double-acting steam engine that he and his business partner Matthew Boulton introduced. By stabilizing their speed, Watt’s fly-ball-governor design prevented these engines from running too fast and self-destructing. This governor usually consisted of two heavy steel or brass balls attached to a vertically rotating shaft. As the engine sped faster, centrifugal forces would cause these balls to spin outward in a wide circle around the shaft, whereupon they would pull a “governor” ring upward. Gravity would then pull the rotating balls back down. Because the governor was connected to a throttle valve, the engine speed would basically be limited and controlled. The “balls to the wall” (or “balls out”) scenario was when the engine was running flat out, at the point there was no more power to be had. The governor balls were spinning as fast as they could—spinning horizontally, to the walls. This graphic characterization was not exclusive to steam engines, though: It was used in connection with early steam-powered locomotives, as in “throttles wide open, giving all she’s got!” World War II fighter pilots also used the term “balls to the wall” in regard to pushing ball-topped throttle levers all the way forward, to the firewall of the aircraft. It meant, in no uncertain terms, that they were going as fast as they could. While today’s “balls to the wall” connotation may have a similar meaning to that of 300 years ago, the true meaning is often lost—much like the meaning of OEE in many plants today. Measuring equipment improvement OEE is a basic concept to help answer this question: “How’s the equipment doing now?” In other words, NOVEMBER 2010

in general (overall) is the equipment doing what it’s supposed to be doing? If not, where’s the problem and what could be causing it? Is it unplanned downtime or scheduled shutdown losses (availability losses)? Is it running inefficiently, stopping for short times or idling (efficiency losses)? Is it running but producing defects and scrap (quality/yield losses)? When improvements get underway, the OEE questions come into play again: “How’s the equipment doing now compared with the last time we looked?” Review availability, efficiency and quality/yield losses. What’s changed? In the beginning, OEE was just that simple—comparing one machine’s performance against itself over a period of time (i.e., measuring equipment effectiveness). Calculating overall equipment effectiveness Supposedly to make things easier, the OEE concept was turned into a formula: Availability % (x) Efficiency % (x) Quality/Yield %. These three factors resulted in a product also called “OEE.” Here’s where it starts getting squirrely. Somewhere in the historical evolution of OEE, we began seeking ways to make our “score” higher—imagine that! Nobody likes a low score, right? So, IF, just IF we factor out “planned shutdown” time, and even time for “planned maintenance,” and then while we’re at it, let’s also factor out “lunch and break times” and “meeting times”… The assumption here? This type of “non-productive” equipment downtime should not be affecting our performance score. When this selective calculation began, OEE took a giant leap for mankind: It started becoming a key performance indicator (KPI) for the maintenance department! OUCH! NOVEMBER 2010
What does an OEE score have to do with the maintenance department? Not much, since most of the causes of the true losses are outside the direct control of the maintenance department and its staff. OEE is about EQUIPMENT effectiveness, not MAINTENANCE effectiveness. OK, some folks got it and realized that OEE was about measuring EQUIPMENT effectiveness as part of Total Productive Maintenance—an equipment-management strategy that engages everyone in the organization, especially those who can influence the root causes of the “major losses” or causes of poor performance. Yet we still see OEE scores (percentages) being used as a KPI in plants on their “lean journeys.” The theory is that a low OEE must signify a problem to be eliminated or a loss or a “waste” to be targeted. But when you dig deeper into the OEE score, it really gets complicated. OEE as it relates to efficiency Efficiency refers to cycle times, design capacity or speed. Thus, whenever product changeovers are performed on a machine, the “efficiency” basis for OEE must also be adjusted to reflect the different cycle times for each specific product. Some take longer than others. In lean plants, the speeds and cycle times often change to match the daily order quantities to be fulfilled. The TAKT time concept (from the German word “Taktzeit,” which translates to “cycle time”) is used to match the pace of production with customer demand. Consequently, the OEE score (percentage) will change when the TAKT time changes and whenever the product changes. In these cases the cycle times used to determine efficiency losses are not fixed. They are highly variable. SO, for true OEE the actual basis for determining efficiency must change for each product. The following Leonardo Da Vinci quote typically comes to mind at this point in the discussion of OEE: “Simplicity is the ultimate sophistication.” What began as a SIMPLE way to think about major equipment-related losses seems to be spinning rapidly out of control, “balls to the wall!” OEE was supposed to measure machine performance improvement over time. Its use, though, has often derailed the pure fascination with eliminating equipment problems and losses. mt-online.com | 9
UPTIME
If our equipment-intensive operations were ‘balls to the wall’ in the quest for productivity and reliability, we could outperform any competitor, anywhere. Beware of the fallacy of OEE scores and percentages. They can be misleading, perverted, misused, misapplied and misinterpreted—and then believed to be one of the purest equipment maintenance metrics of modern time. But don’t get me wrong: Measuring overall equipment effectiveness is very worthwhile. Just keep the factors and associated losses separate (i.e., availability, efficiency and quality/yield losses). Then add metrics for utilization, mean time between failures (MTBF) or mean time between maintenance (MTBM), mean time to repair or restore (MTBR) and some type of cost metric like equipment care and maintenance cost per unit produced, or the big one: Return on Net Assets (RONA). (IMPORTANT: Please don’t try to factor all those together into one big “killer metric!”) Here’s another rule of simplicity, often attributed to the Greek mathematician, Archimedes of Syracuse (287-212 BC)…
“Never guess at it when you can calculate it. Never calculate it when you can measure it.” When calculating OEE, the result is at least six levels removed from the actual cause of the actual loss, which is the beginning of the improvement: eliminating major causes of poor performance. Measure and Pareto-chart the equipment-related losses (I use a list of 14 major ones). Focus on the left side of the chart; these are the major losses. Why calculate when you can (and should) be measuring? What would it be like if our plants and facilities—equipment-intensive operations—were “balls to the wall” in the quest for productivity? For reliability? We would tap all that hidden capacity and outperform any other competitor or nation, anywhere in the world. We can do it if we truly want to. MT RobertMW2@cs.com

Sustaining Partnership Agreements “Most powerful is he who has himself in his own power.” …Seneca We end this “Maintenance Partnership” series of articles as we began five years ago: by stressing that the maintenance department must acknowledge that it cannot—and does not—function autonomously. Maintenance must recognize its success is based on a series of integral inter- and intra-departmental relationships that are set up and managed to provide mutual benefit for all partners. The secret behind all successful partnerships is recognizing the difference between “what you manage” and “what you control.” For example, the maintenance department must manage all machine repairs due to bearing failure, regardless of the cause. Understanding and tracking the cause of failure will differentiate among maintenance-caused events, like lubrication failure; non-maintenance-caused failure events, like overloading (operations-caused); and cost-driven incorrect/sub-quality bearing choice (purchasingcaused). Maintenance-caused events are in the control of the maintenance department and can be eliminated through an improved maintenance process. Non-maintenance events—although they are managed by maintenance—require resolution through negotiation with partners. Resolution is often best managed through the partnered development of a Memorandum Of Understandings (MOU) between maintenance and its partners, in which mutually beneficial agreements are scripted for each partnership. To be successful, maintenance must take the initiative in establishing MOUs and can facilitate the process by soliciting each potential partner and delivering an investment statement that details the roles of the partner and outlines the benefits of the partnership (inputs and outputs). For a potential partner to “buy in” to the concept, maintenance must, from the start, establish its

ability to consistently provide the necessary outputs to its partner, and more important, show that it has the mechanisms and capability to process inputs and turn those inputs into a measured target level of maintenance response, asset availability and asset reliability. As the soliciting partner, maintenance must prepare by understanding its current strengths and improvement opportunities, and by ensuring intra-departmental communication processes are successfully in place. Over the course of our “Maintenance Partnership” series, we’ve seen that the maintenance department is a hub position, which—like a spoke wheel—is inexorably connected through itself to every perimeter department within the organization. The hallmark of a successful maintenance department is the partner recognition of a collaborative relationship that respects the needs and requirements of other corporate departments, coupled with a cognizance of internal maintenance-department needs and requirements and the importance of taking responsibility for itself. This level of partnership sustainability can be achieved in a five-step process. Step 1: Continue to know thyself Regularly review maintenance operation effectiveness. If your maintenance department continues to struggle with the concept of system management, job planning and open information-sharing— finding it easier to take the path of least resistance typical of reactive environments based on personal agendas and limited responsibility—you must perform a maintenance operation effectiveness review (MOER) to audit and score your current strengths and opportunities. This will allow you to take internal control of the maintenance operation. For those who have already done so, regular

communications
MOERs are in order (every one to two years) to establish the level of improvement and resetting of goals based on partnership agreement updates. These audits must address the following: ◆ Planning and scheduling ◆ Work-flow management ◆ Lubrication management ◆ Inventory control ◆ Failure prevention and analysis ◆ Performance indicators ◆ Management reporting Step 2: Know thy future Develop an engineered maintenance-improvement management action plan (MAP). This is a detailed project plan that plots a time-lined series of maintenance-improvement initiatives determined by studying the corporate and department vision, short-term and long-term goals and objectives, budgets and investment returns and preparing a phased implementation of projects that can capitalize on strengths, add measurable value to the maintenance function and be implemented within a specific time frame. Building a MAP requires maintenance to work in partnership with other departments and management to determine the validity of the project. This update process will continue to showcase maintenance and set the stage for partnership MOU development. Step 3: Develop inter-departmental communication tools Working effectively with your partners calls for them to deliver work requests based on minimum information requirements that will lead to planning, scheduling and performing work in a timely manner (inputs). In turn, maintenance will need to deliver communicative documentation regarding requisition needs, work completion and capability status (outputs). Your ability to communicate effectively on an inter-departmental basis will show your partners that you have the ability to consistently provide outputs to help them—as well as be able to act on the input information provided to you. Step 4: Develop partnership input/output matrices The maintenance-improvement initiatives set out in the MAP will require the collaboration of many
NOVEMBER 2010
partnerships to achieve success. For example, ongoing maintenance work calls for purchasing to buy products and/or services on time; production to release the asset; engineering to prepare/ change specs; and vendors and contractors to provide delivery of goods and services, etc. As MOUs are established, the requirements of both sides of the partnership can be built into an input/ output matrix that will facilitate understanding of the commitments undertaken by the parties. Step 5: Meet your partners on a regular basis A MOU should always be a working or living document in which both sides agree to work within the agreement for a period of no less than six months. At such time, the partners can choose to meet and review the agreements for which adherence is difficult and agree to any change requirements, again cementing said agreements for an additional six months of trial. Improvement is a continual process: As your company changes direction, so must your maintenance approach. Now is not the time to procrastinate— it’s a time to innovate. (Going forward, you’ll be hearing much more from me about that concept as it specifically applies to maintenance and reliability. I’ll want to hear about it from you, too.) Staying proactive (and being innovative) in your dealings with numerous partners can be taxing, but nowhere near as taxing as having to play “catch up” on unauthorized or non-negotiated changes. It may or may not be a war out there, today, but the following end-quote is just as relevant and compelling as when it first appeared in The Art of War (more than 2000 years ago):
“Whoever is first in the field and awaits the coming of the enemy will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted.” …Sun Tzu kbannister@engtechindustries.com

T
he first installment of this article (pgs. 14-20 MAINTENANCE TECHNOLOGY, September 2010) ended with a brief look at over-manufacturing—the greatest sin in lean manufacturing. Over-maintenance also is a sin. Performing more of it than is needed or before it’s needed should be considered a waste or an opportunity to improve. This concluding installment picks up with some of the biggest improvement opportunities a maintenance organization has. NOVEMBER 2010
CAPACITY ASSURANCE STRATEGIES
Optimizing preventive maintenance Much has been written—and can still be written—about the optimization of preventive maintenance (PM). This discussion, however, focuses solely on how PM optimization relates to lean maintenance. Optimizing your PM can provide one of the fastest returns on investment you’ll ever realize. If you have a PM system that has all activities documented under each equipment identification number, optimization can be done relatively quickly. If you have a system where all PM activities are documented in a work order, the work becomes much more extensive, if not impossible. If you want to optimize your PM, you must have a system that can collect all PM efforts in a lucid way under respective identities on the maintenance object. This is important because more than 95% of all PM activities are performed as route-based activities while the manufacturing process is running. As a result of increased integration of what lubricators, mechanics, electricians and operators do, the system must always change—and be able to change easily. If your existing PM is based on work orders, the simplest way to begin your optimization efforts is by establishing a route-based system (which can be set up at a very low cost). Today, it’s surprising to find some PM systems continuing to operate much like they did when they were first implemented 30-40 years ago. The distribution of work among different groups is still the same as it was back then. Granted, in many of these companies, operators have become involved in preventive maintenance, but their efforts are combined with other PM measures. Herein lies a great opportunity to optimize numerous PM activities. As an example, in one chemical plant, most pump units still had the following PM measures done: ■ Lubricators lubricate everything, except electric motors. ■ Electric motors are lubricated by electricians. (Even if it’s old-school and a waste of the electricians’ skills, it is still happening.) ■ A mechanical PM inspector performs mechanical inspections. ■ Gear couplings are overhauled during annual scheduled shutdowns. (This could be moved to inspections as the equipment runs, with repairs done as needed.)
After optimizing this system, PM activities were reduced by 50%—and the new activities were considered more effective than before. It can be a good idea to take photos of several pieces of the equipment and show what PM is performed and by whom. Then show how to integrate and optimize all PMs. After that, you can determine costs and savings. Lean shutdown management Depending on the industry, a “shutdown” can vary dramatically in scope, including, for example: ■ Several weeks for a stop in an oil refinery ■ Days for a longer chemical-plant shutdown ■ Hours for a recurring shutdown in many process industries ■ Minutes for manufacturing-operation adjustments and tool changes ■ Seconds for automobile-racing pit stops NASCAR is a good example of what can be accomplished through precision planning, scheduling and execution. Major contributors to pit-stop—or shutdown—performance include communication between operations and maintenance and continuously working on improving the basics of planning and scheduling, execution and root cause problem elimination. In the 1950s, a good pit stop lasted approximately 240 seconds. If nothing had been done to improve these events in the years since (because everyone thought four-minute pit stops were good), we would still be watching them. On the other hand, a crew that could bring those old 240-second pit stops down to the shorter times seen in NASCAR today has the potential to win races. Interestingly, a NASCAR driver is in constant contact with the pit crew. He/she doesn’t suddenly show up in the pit and complain about a problem with a right front tire, only to have the crew answer: “Let us go to the store and check on a replacement tire.” Unfortunately, this happens daily in most plants. In NASCAR competition, there’s a strong motivation to win races; in our plants and facilities, there might be completely different factors driving motivation.

Regardless of the length of a shutdown, the same principles apply in making these events more effective— or leaner. ■ First and foremost, problem-free operation should be possible between scheduled shutdowns. Mean time between production losses (MTBPL) including quality, time and speed should be as long as possible. ■ Shutdowns should be performed with the right quality on all jobs, as quickly as possible. The combination of how many shutdowns you have and how long they are affects both your production volume and your ability to deliver product on time. It is a given that the shutdown must be scheduled (when and who executes what) and that all the jobs must be planned (what, how, all tools, spare parts and materials, lockout/tagout, etc.) before the shutdown begins. In addition, all shutdowns should have a set time for freezing the schedule. After the freezing point, no new jobs will be accepted without harsh criticism. Two measurements can be used to challenge your organization and measure and show improvements. They are as follows: 1. Number of added-on and changed jobs… Define a freezing point for a scheduled shutdown that is to be done within an agreed-upon time frame. Then determine how many jobs are added or changed after the freezing point and during the shutdown. Scrutinize all the added or changed jobs within three days of the shutdown’s completion. Seek explanations for them and learn how they can be avoided next time. 2. Relationship between scheduled and unscheduled shutdowns… With the same definition as in the previous paragraph, we can measure the relationship between scheduled and unscheduled shutdowns. For many process industries, the quota of the equation is over 1— and should steadily increase. This is on the condition that scheduled shutdowns are not programmed and based on old habits, but rather based on market factors and condition monitoring of process and equipment. Determining what jobs actually must be done during a shutdown Many jobs are performed during a shutdown only because they have always been done— done—and no one has ever questioned if they actually need to be done done.

Many jobs are done during a shutdown only because they have always been done. To determine which of them actually MUST be done, you should have a good understanding of the expected life of each respective component. if what you are doing is right, you should have a good understanding of the expected life of each respective component. For example, to regularly change out a roller bearing after 8000–10,000 hours of operation can’t be right. Still, it is a common preventive recommendation from manufacturers. Consider the following issue that came up at a production facility recently: It concerned an OEM’s recommendation to change a centrifuge bearing once per year. The rationale? “The centrifuge rotates with a high rpm, and if a bearing breaks, the rotating unit can cause severe damage, including bodily injury.” According to bearing OEM calculations, the life for a bearing is between one and 15 years (L10–L90 life span). In this application, it’s calculated that 10% break within one year of operation, 10% last longer than 15 years.
This fact alone indicates it is wrong to change the bearings on an annual basis. A bearing that is changed could potentially last for more than 10 years, whereas the replacement bearing might not last more than three. Moreover, there is always a risk that a problem will be induced when a component is changed. Within reliability theory, bearing failures are defined as random failures—you don’t know when they will occur. That also means you can’t know when the component needs to be changed out. “Even though I know it isn’t right to change the bearings, I still do it,” noted the maintenance manager at the facility in question. As he explained, despite his plant manager championing lean manufacturing, becoming lean in maintenance isn’t always comfortable.

You should also ask if jobs that are done during a shutdown could be done during production. One good example of innovation/new thinking involved changing joints of high-voltage lines. With the aid of a helicopter and dynamite, the old joints were improved without disruptions in the power supply [Ref. 1]. Lean- and reliability-based spare parts and materials management In about 50% of operations, spare parts and materials stores reports to the maintenance organization. In the other 50%, it is part of the purchasing function. When an organization wants to become lean, one of the first areas of attack is materials and spare parts. By reducing the value of spare parts and material in storage, you can reduce costs. There are often big opportunities to lower the value in many stores, but such efforts can be very costly if not done right. As an example, one of the most common mistakes is to discard parts that haven’t been used in the past five years or more. This tactic is simplistic and risky— but it’s still being used in many plants today. today Incorrect and expensive cutbacks like this often happen as a result of individuals responsible for the stores pursuing the goal of reducing store value. They may not be concentrating on the consequences of not having the right part in storage when it is needed, which is a real problem for those responsible for operations and maintenance. Most stores, especially in plants that are 10 or more years old, can reduce their value by 10 to 20% without negatively affecting production reliability. To successfully— successfully—and sustainably—reduce the value of parts and material kept in stores, you must focus on measures that drive down the cost, not only on reducing the store value. You should also set up a measurable goal for this effort. It could, for example, be something like “With a service factor maintained at 97%, we will reduce value of inventory kept in stores.” In this case, the service factor would be the percent of occasions the right parts/material have been available when needed for a maintenance job. 1. Knowing what parts and material are in your stores… This is the first information you need. Do a quick evaluation of how accurate the inventory list is. Randomly choose 300 to 500 articles and compare how correct the balance is, the location in the stores, etc. While it may be typical for the inventory catalog to be 70% accurate, 98%+ would be better. But even if your accuracy value is 100%, it doesn’t mean that the stores are cost-effective. Do you have the right articles? Do you have too many? 18 |

2. Determining how many articles exist in undocumented storage… If the inventory catalog and/or the plant register—including component record and spare parts documented for each piece of equipment—aren’t accurate and reliable, users will not trust that the articles they need are going to be available in the store when they need them. This is one of the reasons people start building up their own stores. Such activities can become extensive and very expensive. The costs are invisible. More articles are purchased before they are needed, often in greater quantities than necessary. Even worse, articles frequently are stored in bad environments where they can be damaged by corrosion, dirt, vibrations, etc. It’s imperative to clean up, sort, organize and document all articles in such storages. The store manager will probably not want to take all these items back into the central stores, as they would increase stores value and take up costly space. (Note: Undocumented stores might best be characterized as “emotional stores.” If you make an effort to document them, then take these parts away from the people who have amassed them and put the items in central stores, you’ll understand why the term “emotional” applies.)

The breakdown cost of critical equipment and components compared to the cost of keeping parts in storage is a crucial piece of information. Be sure to take it into consideration when deciding store levels.
identical parts used in the plant equipment, etc., to be missing. Then, only guesses can be made as to what should and should not be kept in storage. It is important to conduct an analysis on what production equipment is critical and which components within each piece of this equipment could cause a breakdown. The breakdown cost compared to the cost of keeping parts in storage is a crucial piece of information that should be taken into consideration when store levels are decided. With good condition monitoring, you can often avoid keeping parts in storage if the so-called failure-developing period is longer than the delivery time of the parts being monitored. A practical example is chains and sprockets made of steel. They wear down over a longer time period, are easy to inspect with objective methods and the delivery times for replacements are typically short. If you monitor wear of sprockets and chains, you can order them when you need them instead of keeping them in storage. Working with an accurate inventory catalog and/or the plant register, including component record and spare parts documented for each piece of equipment, you will know how many identical articles are included in the production equipment. This is necessary and important information to have when evaluating suppliers’ recommendations and decisions on what to keep in stores. The absence of this documentation can lead to storing the wrong parts and quantities. Standardization can also reduce storage substantially. If you have a production line with 22 or so different (and critical) motors, you might decide to keep one of each type in storage. You can often standardize on about five different motors, or even a single type. Then, only five motors—or maybe just one—would need to be stored. Maintaining stored items… You need to keep parts you store in the right environment, free of dust and other contaminants and safe from vibrations. Rotating equipment like electric motors and pumps should have their shafts oriented toward the aisles in the store, so they can be easily rotated to avoid sagging of shafts and damage to bearings. V-belts and other belts made of rubber and similar material should be kept away from daylight (preferably in a dark location). Bearings should be stored flat and turned on a regular basis. Striking greatness Stepping up from good to great in your organization via lean maintenance requires drilling down to the core principles of lean. Understanding and embracing them can help you leverage countless improvement opportunities in your maintenance operations and elsewhere.

oo often in the United States, a worker is severely injured or killed in an electrical arc-flash accident: That’s five to 10 times per day. Other electrical incidents can also harm workers. They typically involve accidental contacts with energized parts that lead to shock and electrocution. The injuries and fatalities resulting from these events can be devastating to workers and their families. The financial consequences can be very damaging to a company. NOVEMBER 2010
SAFETY PAYS
There are important steps that companies can take to reduce the occurrence of electrical accidents and better protect the worker and the employer from the physical, financial and statutory consequences of such incidents. This article covers nine steps for reducing your arc-flash risk. Several of them are required as part of the National Fire Protection Association (NFPA) standard 70E® 2009— which provides a detailed reference for facilities to meet the requirements of electrical workplace safety. The other steps are recommended and considered best practices for improving overall safety within a facility. Clearly, the fundamental requirement for electrical safety is always to place electrical equipment in an electrically safe condition whenever possible through a proper lockout/tagout procedure. But NFPA 70E 2009 provides additional best practices for electrical safety, and these are recognized and enforced by OSHA. NFPA requirements ■ Establishing an electrical safety program with clearly defined responsibilities This is a written document created by the employer that covers all areas of the company’s electrical safety policies. It includes such things as lockout/tagout procedures, internal safety policies and responsibilities for electrical safety. ■ Conducting an electrical-system analysis to determine the degree of arc-flash hazard This analysis is an electrical-system study performed by engineers familiar with the power distribution and control equipment and the calculation methods required. The arc-flash analysis will determine, among other things, the incident energy potential of each piece of electrical distribution equipment in the facility. This incident energy potential will define the Hazard/Risk Category of personal protective equipment (PPE) that the employee is required to wear while performing any work when energized parts are exposed. The methodology for conducting these analyses is outlined in IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations.
■ Using Task Tables 130.7(C)(9) to select PPE One alternative to a detailed arc-flash analysis that is permitted in NFPA 70E 2009 Article 130.3 Exception Number 2 is to use the task tables in 130.7(C)(9) to determine the required PPE Hazard Risk Category. Each table has usage limitations as stated in the footnotes. The footnotes typically specify a range of available fault current and clearing time for the upstream over-current protective device beyond which the tables may not be safely used. Unless a detailed arc-flash analysis has been performed, users will usually not know these details, and this commonly leads to misuse of the task tables, which can lead to under-protection for the worker. The task tables are based on calculated values within the limits of the stated footnotes, but also include the probability of causing an arc flash based on the task being performed. This probability factor is highly variable and subjective, and can potentially lead to significant under-protection. Since the NFPA 70E 2009 Article 130.3(C) now requires that the equipment be labeled with either the incident energy in calories per square centimeter or the PPE hazard Risk Category, using the tables creates a problem with labeling as well. Relying on a detailed arc-flash analysis for PPE selection is always a preferred and more accurate method. ■ Conducting safety training for all workers NFPA 70E defines a qualified person as “one who has skills and knowledge related to the construction and operation of the electrical equipment and systems, and has received safety training to recognize and avoid the hazards involved.” This training requirement means that the employee must have received safety training specific to the hazards of arc flash, arc blast, shock and electrocution. OSHA does not consider electrical workers to be qualified until they have received this specific training.
A fundamental requirement is always to place electrical equipment in an electrically safe condition, whenever possible, through proper lockout/tagout. NFPA 70E 2009 provides additional best practices that are recognized and enforced by OSHA.

■ Ensuring there is adequate personal protective clothing and equipment on hand Employees working in areas where there are potential electrical hazards shall be provided with electrical protective equipment that is appropriate for the specific parts of the body to be protected and for the work to be performed. This can include fire-resistant shirts, pants or coveralls, or a multi-layer flash suit. ■ Ensuring proper tools are on hand for safe electrical work In addition to PPE, the standards require the employer to furnish other tools for safe electrical work. This includes insulated voltage-rated hand tools and insulated voltage-sensing devices that are properly rated for the voltage application of the equipment to be tested. ■ Applying warning labels to all equipment Currently, NFPA 70 dated 2008 (National Electric Code) states in Article 110.16 - Flash Protection: “Electrical equipment, such as switchboards, panelboards, industrial control panels, meter socket enclosures, and motor control centers that are in other than dwelling occupancies and are likely to require examination, adjustment, servicing, or maintenance while energized shall be field marked to warn qualified persons of potential electric arc flash hazards. The marking shall be located so as to be clearly visible to qualified persons before examination, adjustment, servicing, or maintenance of the equipment.” The current NEC requirement for application of hazard warning labels on electrical equipment, National Electrical Code (NEC) 2008, does not require that the specific information, such as the PPE Hazard/Risk Category, incident energy, boundary distances and other data that would be provided by the arc-flash hazard analysis, be included on the label. However, the current NFPA 70E 2009, in Article 130.3(C), has elevated the labeling requirement by stating “Equipment shall be field marked with a label containing either the incident energy or required level of PPE.”
Additional best practices ■ Appointing an electrical-safety program manager Identify someone from your organization who has vast knowledge and experience within the electrical industry. This should be a well-organized, responsible individual who will take the position seriously. Having a single person who is familiar with electrical code requirements and other safety issues will pay off. ■ Maintaining all electrical distribution system components All electrical distribution systems contain active components such as fuses, circuit breakers and relays to help protect the system in the event of an electrical fault. While these components— called over-current protective devices—play a critical role in protecting the system, they’re crucial in protecting workers from arc-flash and arc-blast hazards. Modern, properly adjusted over-current protective devices that have been well maintained are able to detect an arcing condition almost instantaneously and clear the fault quickly. This always results in a significant reduction of the amount of incident energy that’s released. Many existing electrical distribution systems have old components that haven’t been wellmaintained over time. In actual field testing, it’s often apparent their ability to react to an arcing event is much slower than would be the case with a modern, well-maintained device. Unless the protective device optimally reduces the time to clear the fault, the hazard to a worker standing within the flash-protection boundary can dramatically increase. In the past, the maintenance and condition of these devices was not a primary concern for many facility owners, as it often was not clearly understood that poor condition or inadequate maintenance presented an elevated safety hazard for workers. With the current focus on workplace hazards and electrical safety, companies are more vigilant regarding the condition and maintenance of their electrical systems. This requirement for maintenance of electrical distribution equipment has also been incorporated in the NFPA 70E in 2009.
Too often in the United States, workers are injured or killed in electrical arc-flash accidents. That’s five to 10 times per day!

■ Maintaining and updating electrical distribution documentation Electrical distribution system documentation is another important area that’s not been well-managed in many facilities. Documents such as the electrical one-line diagram (essential to safety when performing the lockout/tagout process), short circuit and coordination studies and other critical documents often are poorly maintained. When system components change due to revisions or facility expansions, this documentation is frequently not updated. Lack of attention to documentation management makes the cost and work scope of providing accurate arc-flash
hazard analysis much greater. Since these documents are such a critical part of electrically safe work practices, lack of attention creates additional legal liability if an accident does occur.

How To Begin Maintenance Planning: Writing The Job Plan Raymond L. Atkins Contributing Editor
Effective maintenance is strongly linked to effective job plans. Pay attention to the required components. Don’t skip anything.
L
et’s re-cap: In the first part of this article (pgs. 30-31, MAINTENANCE TECHNOLOGY, August 2010), the discussion focused on how critical maintenance planning is to the success of your maintenance organization. In fact, we made the uncontestable point that your maintenance effort will fail IF YOU DO NOT plan. Let me say that again. Your maintenance effort will fail if you do not plan.
There is no place in the modern maintenance organization for job plans that rely simply upon luck and common sense. You can’t hope your way into a reliable manufacturing process, no matter how many rabbit’s feet you carry. In the last article, we also discussed the importance of selecting the right candidate for the job of maintenance planner. Planning is a meticulous and detailoriented job, and if you want your planning initiative to succeed, your planner will have to exhibit those qualities. Close enough is not good enough when writing a job plan. It has to be perfect. It is an exercise in absolutes. That said, let’s now turn our attention to the creation of a good job plan. 26 | MAINTENANCE TEChNOLOgy
There are several components to a good job plan— the order in which you assemble these pieces is not nearly as important as the fact that none of them are to be skipped. We’ll get to the best way to put them into the job packet later. The various components of a complete job plan include: job steps; tool list; skills roster; bill of materials (BOM) and parts list; diagrams, photographs, illustrations; standard maintenance procedures (SMPs); and safety, including lockout and personal protective equipment (PPE). It’s often helpful to read several job plans written by others before beginning, just to get the feel for what the end product should look like. My recommendation is to begin by writing down the actual job steps. The procedure should be written as a numbered list with each number representing one of the NOVEMBER 2010
A SPECIAL SUPPLEMENT TO MAINTENANCE TECHNOLOGY
finite steps of the job. This list will also serve as an outline for your planner as he/she puts together the job packet. The steps should, of course, be recorded in the order they are to occur. If the planner happens to be a former technician who has performed the task before, then this portion of the process should be pretty straightforward. If the planner has not performed the job before, he/she must consult with someone who has. If the job being planned has not been performed by any current employee, it is strongly recommended that you hire an outside contractor or a factory representative to not only help write the job plan, but assist in doing the actual job as well. When it comes to industrial maintenance, there is no substitute for knowledge and experience. Notes on providing job-step specificity… I have been asked on several occasions about just how specific the written job steps should be, and my answer is always the same: Your job steps should be as specific as needed to successfully complete the work at hand. I’m not being a wise guy—it depends on your maintenance organization and the level to which your technicians have been trained. Keep the least skilled in mind. If all your millwrights have been properly trained in torque specifications and know how many foot-pounds of torque a grade-eight bolt requires, then that job step can be written in general terms. If, however, they haven’t been trained in torque specifications and if you don’t want to have a rash of looseness issues over the coming months, your planner had better spell out quite plainly that the ½” bolt should be torqued to 119 foot-pounds. The same concept holds true for belt tension, sprocket alignment, bearing installation, fan balancing, motor wiring, hose construction and countless other tasks. If the planner knows that the millwrights and technicians have been recently checked-out on the task, then that task can be referred to in less-specific terms. There is one final note about the job-steps portion of the job plan. The work-order document should be designed with adequate space for a technician to jot notes and comments on it. Doing just that should be a departmental requirement, rather than a suggestion. The job plan is a living document, and each time the job is performed there should be valuable feedback from the field that can be incorporated back into the plan. The idea is to eventually arrive at the one safest, most effective and most efficient way to do the job. Additionally, there should be spaces for the maintenance professionals to sign off that they have completed the work according to the specifications laid out in the document. This step is nothing less than crucial. Accountability must be embraced in any maintenance department if it is to succeed. NOVEMBER 2010
Notes on constructing a tool list… Once the job steps have been written down in order and checked by a maintenance professional for errors or omissions, the next step is to analyze the job with an eye to constructing the tool list. The tools referred to here are in addition to those that we would normally expect to find in a multicraft’s tool pouch— they’re specific tools required to do the job. These items might include welders, torches, shackles, straps, cables, cranes, comealongs, jacks, porta-powers, alignment and measurement devices, specialty tools, power tools, man lifts, forklifts and a large variety of other things not needed for every job. This is a critical step that must not be skipped by the planner. (I would venture that there is not a single reader of this article who hasn’t had at least one major job grind to a halt because the need for a specialty tool was not planned for.) Notes on constructing a skills roster… The skills roster is, in many ways, similar to the tool list. The difference is that while your tool list specifies the exact tools that will be needed to successfully complete a job, this roster is a list of the skill sets that will be required to finish the task. Many organizations are moving (or have moved) toward multicraft status for their maintenance professionals. In these cases, the assumption would be that any employee who picks up the work packet could perform all of the tasks that the job calls for. But even in a multicraft organization—and especially in a non-multicraft environment—the truth is that some maintenance professionals are better at certain things than others. Thus, it’s always better to list the skill sets that will be needed to complete the project. A few of these specialties might include welding, cutting, fabrication, millwright, hydraulics specialist, electrician, plc programmer, pneumatics specialist, machine operator, alignment technician, reliability technician and machine-specific technician. Notes on constructing a bill of materials and parts list… The bill of materials (BOM) and parts list is one of the most important portions of the job plan. It represents, literally, the nuts and bolts of the job. As such, it should be as specific as possible. Parts should be listed by both part number and description, and no job plan should progress to the ready stage until every part is on hand and has been verified to be the correct part. This specificity is not only important with regards to parts. Materials such as wire nuts, epoxy, twistties, shims, loose steel, grease, nuts, bolts, washers, rubber hose, O-rings and hundreds of other non-job-specific materials must be listed on the job plan, and when the job is scheduled, these materials must be verified as being on-hand and available for use. In addition to being a complete record of all parts and materials, your BOM and parts list should also indicate any special disposal instructions for removed or replaced parts. MT-ONLINE.COM | 27

Notes on compiling diagrams, photographs and/or illustrations… Everyone has heard the old saying that a picture is worth a thousand words. That’s an understatement when it comes to a maintenance job plan. Your planner literally cannot include too much illustrative material with a job plan. A good planner should take advantage of the fact that we live in a digital world and illustrate job plans accordingly. Even something as simple as a good color picture of the job site with a circle drawn around the part to be replaced or repaired can be a great help to a team of technicians unfamiliar with the job. Each diagram, photo and/or illustration should be numbered or lettered and referred to with that designation in the appropriate written job step—as in “See Illustration #2” or “Refer to Diagram A.” Specific materials that come with parts should be handled in the same manner, with copies of the instruction sheets being included in the job packet while the original remains with the part. Notes on including standard maintenance procedures (SMPs)… It’s helpful to include copies of specific SMPs in the job plan if those procedures are necessary to the successful completion of the job. As discussed earlier, if you have confidence that your maintenance professionals are performing in practice at the same level that they are on paper, this step may not be necessary. But your planner should include the SMP if there is any doubt that any member of your staff may find himself or herself out in the field under the pressure of a deadline not knowing how to perform a task. Remember that a job plan must be written with your least-skilled technician in mind, because that is the person who might draw the work. An SMP is, in reality, a small job plan, and it is designed to impart information to those who need it. Medical ad 2007E

Notes on addressing safety, lockout and PPE … After the rest of the job plan is written, the planner has all of the necessary components to be able to write the crucial safety portion of the job plan. Once the scope of the work has been determined, critical information such as which machines to lock out, what PPE will be required and which safety protocols must be observed can be determined. The planner should consult with a millwright familiar with the machine, an operator and the safety manager or safety committee when outlining the safety components of the job plan. Notes on assembling the job packet… After all components of the job plan have been completed, it is time to put together the job packet. The order I recommend is:

BOOSTING YOUR BOTTOM LINE
Life-Cycle Cost: The Real Purchase Price
L
ife-cycle cost (LCC) analysis is a powerful method of evaluating the total costs over the lifetime of equipment or systems. A basic LCC analysis will reflect purchase, installation, operation, maintenance and disposal costs. Looking beyond the initial purchase price will help you understand where your organization spends its money. For example, did you know that the electricity used to power a motor represents approximately 95% of its total lifetime cost, including its purchase price? In many organizations, however, typically only the “initial costs”—such as purchase price and installation—are considered when investing in new equipment. Why aren’t life-cycle costs calculated more often? For one thing, these analyses require collection of additional financial data beyond initial cost. While the thought of gathering this information may seem daunting, you may need less than you think to get started. For assessing basic equipment like motors and drives, begin with the following simple formula to get a ballpark estimate of lifetime cost. You’ll need to know initial purchase and installation costs (I); expected life of the system in years (L); yearly cost of operation and maintenance (O&M)—be sure to include energy costs; expected yearly repair costs (R); and disposal costs (D) or salvage value (S). Make use of accepted industry estimates, spec sheets and your own facility’s cost data for similar equipment: Simple LCC = I + L(O&M + R) + D - S What can be learned from this basic analysis? In the case of motors, O&M energy costs are often significant—so much so that they can overshadow initial purchase and installation costs. Now imagine considering the operation and maintenance costs across your entire system. Studies show that making investments to minimize energy consumption and minimize unscheduled downtime are some of the most effective ways to improve profitability[1]. Thus, you can see how

important it is to conduct an LCC analysis before investing in new equipment or making major changes to processes. Where can you get further help? A number of excellent resources provide LCC tools and training. For example, the U.S. Department of Energy’s Industrial Technologies Program (www1.eere. energy.gov/industry) has a wealth of assessment tools for fan, pump, steam, process heating and motor systems to help industry save energy and money and increase productivity. ASTM International (www.astm.org) documents standard industry procedures for analyzing life-cycle costs. The Motor Decisions MatterSM Campaign (www.motorsmatter.org) has developed a suite of calculation tools and brochures to help you and your team make quick back-of-theenvelope LCC estimates. Take advantage of these resources. LCC analyses will help you understand the real purchase price of your equipment and keep your operation focused on the bottom line.

Duke Energy Generation Services Partners With Others On Nationwide Solar Efforts
D
uke Energy Generation Services (DEGS) and two partners have announced plans to build and finance distributed solar projects across the United States. Based on the deal, DEGS (part of Duke Energy Corp.’s Commercial Businesses) and Integrys Energy Services (a subsidiary of Integrys Energy Group) will focus on jointly owning rooftop and smaller groundmounted photovoltaic (PV) solar projects that deliver electricity to investment-grade commercial, government and utility customers under long-term power-purchase agreements. Smart Energy Capital, the third partner, will develop the projects and arrange financing. While DEGS and Integrys will continue to independently develop commercial solar projects pursuant to their own corporate strategies,
their new working relationship will serve as a way to cooperatively boost growth in an attractive segment of the solar market. The structure of the partnership is expected to help create an end-to-end approach for bringing solar projects to market. It also will let DEGS and Integrys monetize available federal tax benefits associated with the projects. Terms of the agreement call for DEGS and Integrys to equally supply the necessary equity capital for construction and ownership of the distributed solar projects, and also be responsible for operating and maintaining them. The companies have said they intend to invest up to $180 million in total capital over the next two years. Individual project size is expected to be 500 kilowatts and up, depending on customer needs. “What makes this partnership unique is its focus on distributed
solar solutions that produce renewable electricity close to where it is used, rather than at centralized power plants,” said Greg Wolf, DEGS senior vice president, in an industry release. He added that the companies involved bring a wealth of project development, construction, management and financing expertise to the table. Integrys, for example, has already invested more than $65 million in 20 different distributed generation solar projects across the United States with a combined capacity of more than 10 megawatts. For its part, Smart Energy Capital is especially pleased with the agreement. As Rob Krugel, its managing partner noted, “We believe this partnership provides a solution to one of the fundamental challenges in the commercial segment of the solar market: reliability and certainty of financing.”

ccording to Thompson Pump, its new pumps with OVT (oil-less vacuum technology) priming offer a number of improvements over those with traditional vacuum priming. While both allow for a basic pump to prime automatically, the company says the OVT does it more efficiently with lower maintenance and higher air-handling. Among their many features are noncontacting rotors that eliminate internal wear, leading to increased reliability and service life. Dry-running and air-cooled, these units require no recirculating oil, have no water levels to check and no cooling systems to maintain. Removing the oil from the priming system eliminates sources of smoke, mist or pollution that can be associated with traditional systems.

A Powerful Case For Infrared Windows See what you’ve missed! Numbers based on the real-world experience of a power-gen facility show significant ROI. Martin Robinson IEng., CMRP Level 3 Thermographer IRISS, Inc.
34 | MAINTENANCE TEChNology
T
he insurance carrier of a regional power-generation facility asked the company to perform regular preventive maintenance on the switchgear within its operations. Unfortunately, regular downtime was not a practical option for the power plant, as the processes required to do the live inspections were hazardous and required more manpower and resources than the facility could provide. Management began to seriously re-think its strategy: In light of NFPA 70E, inspections of energized equipment were becoming more restrictive, more time-consuming and more costly.
NOVEMBER 2010
PROCESS IMPROVEMENTS
What had not been seen The insurance carrier had already done the necessary research and determined that the power plant could achieve a reduction in hazard liability and maintenance costs through the use of infrared windows. Benefits included: nUtilization of IR windows for routine inspections of healthy equipment did not require the elevated levels of PPE required in 70E, since, as stated in 70E 100: “Under normal operating conditions, enclosed energized equipment that has been properly installed and maintained is not likely to pose an arc flash hazard.” n Maintaining an “enclosed” state for the switchgear, motor control center (MCC), transformer, etc., maintains energized components and circuit parts in a “guarded” condition, in NFPA terms. Therefore, the hazard/risk category would be equal to reading a panel meter, using a visual inspection pane for lockout/tagout confirmations or walking past enclosed, energized equipment— and the inspection could even be conducted during peak hours for best diagnostic data. n Use of IR windows would eliminate the need for a supporting cast of electricians to remove and reinstall panel covers, as well as allow critical personnel to be available for other tasks that were often being outsourced. nThe ability to perform more frequent inspections of critical or suspect applications would help ensure plant uptime while at the same time reduce insurance liabilities. The overall focus was to facilitate inspection of the primary switchgear in the facility’s electrical distribution system and several smaller operations within the plant. An impending shutdown increased the sense of urgency, since all Phase I installation could be fitted during that period. IRISS performed an on-site inspection to ascertain the optimal position and quantity of windows that would give thermographers thorough visibility of desired targets. It found that none of the primary switchgear or transformers had been included in the site’s inspections. The reason: inherent safety hazards associated with their being safely inspected while energized (see Table I). Based on this information, the primary goal of Phase I of the IR window installation was to bring this equipment into the standard inspection routes—and more important, allow the inspections to be conducted in line with NFPA and OSHA safety mandates. A time study was then completed, detailing the man-hours and the costs involved in completing Phase I.

Typical cost analysis of traditional inspection… The power-gen facility had previously been using a contract thermography company, with a survey crew made up of two in-house electricians and one contract thermographer. The hourly wrench time (time spent on productive labor) rate for the electrician was calculated at $62, and the contract thermographer’s rate was $150 per hour ($1200 a day). Typically, the equipment being considered for Phase I window retrofitting would require 19 days to complete. This translated into 497.7 billable hours (see Table II). Alarmingly, as the task breakdown in Table II also shows, there were a staggering number of unproductive man-hours (94% of the total project time) associated with the standard inspection activities. n In accordance with NFPA 70E and OSHA mandates for energized work, the entire inspection team dressed in 40 Cal/cm2 PPE (personal protective equipment). Team members spent an average of 30 minutes to suit-up and dress-down—twice a day. This was a total of 57 hours related to PPE over a 19-day cycle. n The thermographer spent 117.6 hours simply waiting for panel covers to be opened/closed to provide him access. n The electricians spent 58.8 hours (29.4 hours x two men) waiting for the thermographer to complete his work once the panels were removed.

The benefits of IR windows… In his investigation of the technology, the power-generator’s corporate reliability engineer determined that IR windows: n Would provide non-intrusive access to electrical applications. Surveys could be conducted during periods of peak-load without elevating risk to either plant assets or processes. 36 | MAINTENANCE technology
n Would eliminate the need for a supporting cast of electricians to remove and reinstall panel covers. These critical personnel would then be available to perform other tasks which were often being outsourced. n Would eliminate high-risk tasks during inspections (through closed-panel inspection), thus increasing safety for thermographers. n Would not require the elevated PPE levels mandated in 70E (for routine healthy-equipment inspection), since 70E 100 notes: “Under normal operating conditions, enclosed energized equipment that has been properly installed and maintained is not likely to pose an arc flash hazard.” n Would, in NFPA terms, maintain electrical equipment in an “enclosed” state and maintain energized components and circuit parts in a “guarded” condition. Thus, the hazard/risk category would be equivalent to reading a panel meter, using a visual inspection pane for lockout/ tagout confirmation or walking past enclosed, energized equipment. n Would improve inspection efficiency. It also would allow increased inspection frequency for mission-critical or suspect applications. Investment The facility’s 95 applications with 147 inspection compartments required 203 infrared inspection windows. The 203 installed IRISS infrared windows represented an investment of $48,841.00, including contract-labor installation time. The IR-window installation… The installation of the inspection panes was conducted during a shutdown, using two install teams. The majority of the windows were installed while equipment was de-energized, in what NFPA terms an “electrically safe work condition.” Some installations, however, involved energized gear and needed to employ the traditional safety measures such as use of PPE, energized work permits, etc. The work occurred during normal business hours since this allowed more flexibility. Cost analysis of inspection with IR windows… With the infrared windows installed, there was no requirement to remove panels or wear increased levels of PPE. In addition, inspections could now be performed on their applications that had previously been considered “uninspectable.” Finally, the entire task became a one-person job. These IR windows also increased efficiency and economyof-motion. Total personnel-hours to complete an inspection dropped to just 33. As a result, plant surveys of equipment NOVEMBER 2010

dropped from a cost of almost $45,484 to just under $4950 (see Table IV). Because of these efficiencies, the facility now spends $40,534 less per inspection than it did prior to the installation of the windows—translating into a savings of more than 90%. Table IV.

Calculating return on investment Table V combines data from previous tables to illustrate the return on investment (ROI) that the power plant realized from Phase I of its infrared window program. This information details the total investment using two scenarios: 1) traditional open-panel inspections with a contract thermographer and two staff electricians; and 2) the same contractor using IR windows. Switching to the windows was shown to pay dividends in just two inspection cycles—producing more than $33,227 in savings that can be put back into the budget by the end of the second cycle. After five inspection cycles, the savings were over $153,829. Because inspections can now be completed with greater ease and without increased risk to the plant, the personnel and the processes, the operation increased the frequency to a quarterly basis, reflecting best-practice recommendations that originally were not considered feasible.
more than $33,227 in savings. After five inspection cycles, the savings had grown to over $153,829.
Conclusion The new inspection process using infrared windows brought substantial ROI to the plant in just two inspection cycles, while reducing the risk of catastrophic failure of the site’s critical power-distribution systems. Management succeeded in:

viewpoint John Berra
Looking Back / Moving Forward John Berra began working in 1969 as an instrument engineer for Monsanto. He recently retired after a distinguished career that included championing industry standards such as HART and FOUNDATION fieldbus and serving as president of Emerson Process Management.
A
s part of the automation industry for 41 years, I have seen significant changes in technologies and applications. One of the biggest has been the direct impact of automation on overall plant maintenance. Forty years ago, the automation system controlled the process, and that was it. There was no direct connection to maintenance. But as digital technology brought new capabilities to field instruments as well as automation systems, people started asking, “What else can we do with this?” The result is today’s embedded diagnostics and predictive intelligence. Now we can use the intelligence built into our instruments, pumps, motors and other equipment to shape our maintenance strategy. We can use predictive intelligence to detect when something’s going wrong and fix the problem before it grows. We can identify frequent offenders and focus our efforts where they will do the most good. We can even eliminate unnecessary maintenance—including the ever-popular “no fault found” maintenance trip. Another big change has been in the knowledge required of maintenance engineers and technicians coupled with the scarcity of people who have that knowledge. Maintaining yesterday’s pneumatic controls took mostly mechanical skills. Today’s maintenance worker, though, also has to know electronics, networking, software and more. At the same time, a lot of people my age are exiting the workforce. We’ve built up a lot of knowledge and experience that newer workers don’t have yet.
One way to fill these experience and expertise gaps is through knowledge management—not just documenting best practices, but using technology to leverage the experts we do have, wherever they are. These days, it’s not unusual for a compressor expert in London to troubleshoot a compressor in Indonesia. Wireless technology also makes it easier for workers to get the information they need. For example, technicians can temporarily instrument a unit to gather troubleshooting data, then easily move the wireless instruments to the next place they’re needed. Maybe the most important maintenance tool of the future will be a wireless tablet—something along the lines of an “industrial iPad.” It will give workers an instant view of what’s happening in the plant and the ability to “talk” to a piece of equipment to see what’s working right and what’s not. They can use it to access drawings and instructions, check with the OEM for recommended practices, even order parts, all from the plant floor. Technologies like these can be especially important for plants in developing markets, where it’s hard to find experienced maintenance personnel. However, even mature-market plants built decades ago can leverage these types of new tools and methods to get the most out of their dwindling staffs and aging assets—and compete with all those brand-new plants! I’m glad to see more and more companies view maintenance as part of an overall strategy for competing in a global marketplace. Maintenance can no longer be just what you do when something breaks, as it often was when I started my career. Now it is how you improve reliability, safety and production to gain a competitive advantage. Looking back is fun, but looking forward is better. Someone once said that the best way to predict the future is to invent it. I’m confident that the innovators will continue to invent a better future for all of us. MT
