Things to Think About and Do in 2012: Advantage


Below is an excerpt from ReliabilityWeb.com's E-Book: Things to Think About and Do in 2012.

The simple reality is that maintenance departments are cost centers. This means maintenance costs the company money and does not provide a value-added service to the end customer. In short, maintenance departments do not create salable product, yet your job exists solely to support salable product.

Therefore, maintenance must be managed as a competitive advantage. By changing organizational thinking to view maintenance as a competitive advantage, more innovative ideas are implemented. To affect this shift, maintenance is measured by the value produced. First run output becomes a direct measure of equipment capability, therefore reliability.

Reliability value is measured by the maintenance cost of the best sustainable run output. Sustainable output length is organization dependent; common timeframes include 90 shifts, 3 months, outage to outage.

Reliability Value
Best 90 shift output=9,000 widgets
10 hours/shift yields=10 widgets/hour
Maintenance costs for timeframe= $500,000
Maintenance cost/widget= $55.56

Whenever maintenance costs are below $55.56/widget, the company sustains a competitive advantage. That advantage can be used in profit taking, or in lowering the product price to gain market share.
Maintenance decisions are now based on cost per widget. Consider the decision to enter into condition-based monitoring (CBM) at monthly costs of $10,000. To be advantageous, the program must guarantee an additional 180 widgets ($10,000/$55.56 dollars/widget). At 10 widgets/hour, the program must improve equipment uptime more than 18 hours/month.

Under cost center thinking, a $10,000/month CBM program would be an unlikely approval. However, when viewed under the competitive advantage model, it can be approved because there is a tangible measure of success—hours of equipment uptime.

Maximum CMMS: Finding Answers For Efficiency, Part 3


Published on Facilitesnet.com, the article below is the final excerpt from a three-part series written by Kris Bagadia.  

Maximum CMMS: Maintenance Mobility

Today's handheld devices bring an added level of functionality to CMMS. The mobility they allow brings greater efficiency to technicians in the field. Consider these examples of the benefits of mobile technology:
  • Readings. Technicians who use handheld devices servicing equipment and assets, such as boilers and chillers, can collect key pieces of data, including pressure, temperature, and oil levels. If they find abnormal based on user-defined criteria, the CMMS will send a warning. They can also monitor security checks, perform inspection routes and record runtime data.
  • Work orders. Managers and supervisors can distribute work orders using a handheld device. The technicians can perform the actual work with instructions on handhelds, enter data on time taken and work performed, and close the work orders. All the related information is transferred into CMMS, either real time or via a cradle. Departments also can generate work orders using handhelds. You can establish a completely paperless work order system if desired.
  • Parts inventory. This area offers an excellent opportunity for managers to use mobile CMMS technology to save money. Storeroom attendants using handheld devices can handle parts receiving, additions and depletions, cycle counts, and annual physical inventory very efficiently. They can issue an item to an employee, work order or an account number, as well as return the issued item to the inventory.
Successfully specifying and implementing a CMMS ultimately will require top management's commitment to stay involved with the project and provide needed support and resources. If these things occurs, the result will be a CMMS that properly facilitates daily technician activities, resulting in efficiencies not possible with manual systems.

Perhaps more importantly, a CMMS also can provide comprehensive information and analysis for managers that support fact-based decisions enabling greater optimization and accountability throughout the organization.

Maximum CMMS: Finding Answers For Efficiency, Part 2

Published on Facilitesnet.com, the article below is an excerpt from a three-part series written by Kris Bagadia.  

CMMS Specification Solutions

Managers whose departments use only a fraction of a CMMS's available features did not specify the most appropriate software. It means the application has many bells and whistles the department does not need. The incorrect selection decision costs the company money on the software's acquisition, as well as user training — money the manager could have saved by specifying the most appropriate package based on department needs.

Whether you are upgrading to a newer version of the CMMS or acquiring a new CMMS, selecting the right package is crucial to a successful implementation and enabling the department to fully use the CMMS's features and functions. Managers should consider answer these specification questions:
  • Is it easy to use and flexible? The CMMS should be designed for front-line maintenance technicians, not computer experts. The system has to be flexible enough to accommodate the way they carry out their daily tasks, not the other way around.
  • Does it handle queries and reporting effectively? These are two very important functions of a CMMS. Once the implementation is complete, users each day retrieve the desired information and generate reports to help managers make more informed decisions. Managers should be able to retrieve any information required, when they need it and in the desired format. 
  • Does it improve workflow? An efficient flow of work — initiating and approving a work request, planning, scheduling, dispatching, completing it, and following up for continuous improvement — is essential for productivity. A CMMS's work-request system enhances the efficiency of the maintenance operation, as well as the requester's productivity. Requesters must have convenient access to the status of open and completed work requests, which prevents dips in productivity by helping them identify and dispose of duplicate requests.

    Enabling customers to enter and view their work requests increases efficiency for both the requester and the maintenance department by substantially reducing the number of repeated requests to perform these functions. Repeated calls are a significant drain on productivity, not only due to the time they consume but also because of the unplanned interruption of work by the technician.
  • Does it provide a satisfactory parts list? A CMMS should have a provision for specifying parts and tools on PM work orders so technicians can arrive on the job site prepared with required parts, resulting in less downtime.

Maximum CMMS: Finding Answers For Efficiency, Part 1

Published on Facilitesnet.com, the article below is an excerpt from a three-part series written by Kris Bagadia. 

Optimizing your CMMS 

How much of your computerized maintenance management system (CMMS) does your department actually use? The answer to that question is not as straightforward as it might seem. My national survey of CMMS users indicates 94 percent of them use only 10 percent of the software's capacity and features.

Many institutional and commercial facilities use a CMMS as a recordkeeping tool. If that is all they want, a spreadsheet might suffice. Specified, installed and operated properly, a CMMS is a powerful tool that goes far beyond recordkeeping.

By not fully using the CMMS, maintenance and engineering departments are missing out on opportunities to save time and money. And as the utilization of CMMS increases, overall productivity and profitability also increases. 

Spotlight On Benefits 

A properly implemented CMMS increases technicians' overall productivity by improving the work-process flow, helping migrate from reactive to proactive mode, and incorporating PM optimization and trending analysis, among other benefits. It also will improve efficiency and customer satisfaction by organizing, distributing and managing maintenance-related information, as well as eliminating inefficiencies arising from information bottlenecks.

A CMMS provides all stakeholders with real-time information relevant to their responsibilities and activities. Maintenance technicians can obtain a prioritized list of open work orders.  

Requesters can check status information without interrupting maintenance technicians. Service managers can view reports of backlogged work orders, including total estimated backlog hours. Top management can produce comprehensive reports profiling resource utilization and compliance requirements. 

As part of a department's continuous-improvement program, a CMMS can be an excellent tool to identify non-value-added activities and shorten process cycle-times. Maintenance and engineering departments too often spend a great deal of time waiting for parts, approval, instructions and equipment. A CMMS can help managers identify the activities and equipment costing the department the most time and money, enabling them to analyze the situation and correct it. 

A CMMS also can become a powerful tool for analyzing data and using that data to make meaningful decisions. For example, reviewing compliance with work-order schedules, ratios of PM and repair work orders compared to total work orders, and then taking the necessary corrective action. Maintenance departments frequently gather readings on a variety of equipment, such as boilers and chillers. In a paper-based system, technicians and system administrators fill out forms out and file them away, too often never to be found again. Some companies have started using a CMMS to record and save readings of say, pressure and temperature. Using this data, technicians can identify abnormal readings and correct problems to prevent failures. 

Once technicians have defined a certain range of values and criteria, the CMMS will issue a warning immediately upon the reading meeting those criteria. Maintenance planning also can automatically incorporate usage- and condition-based PM, as well as predictive and corrective maintenance, based on abnormal readings.

Can the U.S. Revitalize its Infrastructure?


Pushing the limits of an aging infrastructure, U.S. manufacturers face a future of increasing costs and instability unless new technologies and new investments can rejuvenate the system.


The following article was written by Travis Hessman of IndustryWeek

On Sept. 8, 2011, an Arizona Public Service field technician was sent out to a North Gila, Ariz., substation to switch a capacitor bank -- a routine job the technician had performed a dozen or so times before.

This time, however, he missed a step in the process, which knocked out the entire 500-kilovolt transmission line running through the substation.

Under normal circumstances, this wouldn't be a big deal. With a solid infrastructure operating within standard guidelines, this should have resulted in a brief, isolated outage.

But in our overstressed and under-maintained grid, that single transmission line was all that connected the region. Losing it sent a cascade of outages down the system, blacking out enormous swathes of Arizona, Mexico and Southern California, including all of San Diego and its 1.5 million customers.
Andrew Herrmann:
"By making investments, you are actually saving money."
In total, the outage left about 2.7 million customers without power -- the second-most significant outage of the year next to the one resulting from Hurricane Irene.

For the hundreds of manufacturers scattered throughout the region, the outage was costly. According to the U.S. Department of Energy, these kinds of power failures cost companies between $20,000 and $2 million.
This was not a rare occurrence. In 2011, California led the country in outages with 371 -- more than double that of second place New York.
Such events confound an already-difficult environment for manufacturers trying to stay ahead in the United States today. Maintaining a profitable, competitive business with an infrastructure this shaky is increasingly difficult, and manufacturers are left largely unarmed in the fight to bring in the kind of investments necessary to change it.

So the question must be asked: Can the United States revitalize its infrastructure to provide manufacturers and businesses a competitive environment in which to operate and prosper?

 

State of the Infrastructure

The U.S. infrastructure was in bad shape coming into this decade. Rated "D" for overall performance by the American Society of Civil Engineers (ASCE) in 2009, the entire system proved in dire need of some much overdue investment to catch up with global competitors.

"There is a real sense of urgency right now within the United States," says John McDonald, director of Technical Strategy and Policy Development for the Digital Energy division of General Electric Co. (IW 500/4). "We have an infrastructure that wasn't maintained very well for a long period of time. It's getting older, so the chances of catastrophic failure are now greater than they have been."

Catching the system up after such neglect to prevent this kind of failure will require an investment of $2.2 trillion over the next five years, says ASCE President Andrew Herrmann. And that is just to make a "B" on the next infrastructure report card.

Failure to make this investment, he says, will cost the United States hundreds of thousands of jobs and hundreds of billions from the GDP.

For the electric infrastructure alone, interrupted operation due to blackouts, brownouts and unstable supply could cost business an estimated $126 billion or more annually. To prevent this, the federal government, states or utilities would have to invest $11 billion per year, Herrmann says.

Though costly, "this would protect about 529,000 jobs, $656 billion in personal income, about $500 billion in gross domestic product and $10 billion in exports," he explains.

With manufacturers consuming one-third of the nation's total energy per year and total energy consumption expected to increase as much as 39% this decade in some regions, according to the World Resources Institute, the electrical grid becomes a critical piece of infrastructure to protect and maintain for U.S. manufacturers to remain competitive. It is critical for them even to stay solvent in today's environment.

With this kind of threat hanging over U.S. manufacturing, there is an increased need now to double-down on infrastructure investment on every level to help keep the United States in a competitive position, says Herrmann.

"We have an infrastructure in the United States that was essentially investments from the 1950s and 1960s. It's getting old," he explains. "If you don't maintain it, if you cut back on those maintenance budgets or the rehab budgets, it just gets older, and by not doing anything, the life actually gets shorter."

For the past few years, investment toward rehabilitating the aging infrastructure has been directed at a new technology that promises to help improve efficiency and productivity all through the system: the smart grid.

 

Smart Grid

The smart grid refers to a class of technology used to help bring utility electricity delivery systems into the 21st century, via computer-based remote control and automation, according to the Energy Department.

These systems help eliminate the labor-intensive meter reading and maintenance required of the old-fashioned (or "dumb") grid for the past century -- possibly including the kind of work that caused the 2011 Southwest outage.

Though still in its infancy in many respects, boosted by heavy investment from the federal stimulus, smart-grid devices are beginning to be used on electricity networks all the way from the power plants to the consumers .

With the automation this technology provides, "instead of building a new substation or buying new lines or purchasing more power, what utilities are doing is making better use of their existing infrastructure by improving efficiency," says GE's McDonald.

 

Distributed Generation

One way the smart grid is enabling improved efficiency is through distributed generation.

Capturing energy collected by solar arrays on private businesses and residences across the system and feeding it back into the grid, distributed generation works to help reduce energy strain by providing increased supply to every user during hot, sunny days when they need it the most.

With 3,360 solar panels installed atop its Chino-Calif. facility, Diamond Wipes International is able to produce twice the energy it consumes, which may save the company as much as $135,000 this year in energy costs while also contributing heavily to the overall power supply, says Tom Hill, vice president of marketing and sales at Diamond Wipes.

"We are a net benefit to the level of power in the overall grid at any point in time. That energy we are sending back is not really being stored, it is being used by other users of the power grid," he explains. "We are drinking from the great fount, and we are contributing daily into the overall system, which is being used by others."

On its face, distributed generation sounds as neat and beneficial as Hill describes it -- businesses work with the power companies to lower the strain on the grid, offsetting high-demand peak hours with green-energy supply, thus meeting the state's low-emissions requirements. But as Gregg Turner, director, Utility Segment at Eaton Corp. (IW 500/72) points out, the equipment on the utility side may not be ready for it.

The grid, he says, is still primarily designed to carry power only one way -- from the power plants to the customers. As power gets injected at the ends from distributed generation systems, he says, something as benign as a patch of clouds can spike and ultimately crash the system.

"What happens is, utilities are faced with periods where power is injected back into the substation on one leg while other legs are trying to feed out their normal loads," says Turner. "[This] causes a level of unbalance that, if not properly managed, results in the substation going entirely offline."

Power flowing intermittently in different directions to and from manufacturers, he says, actually increases the operational stress on the system and can result in increased instability -- exactly what the system was designed to prevent.

 

The Solution

The key to making this technology work -- and really the key to revitalizing infrastructure in general -- is investment. Traditionally, this has meant cash injections from the federal level, but in the current political environment, there is little hope of this coming through.

"Right now, we have limited power in DC," explains Herrmann. "We have discussions between the two parties, but they aren't agreeing to too much of anything. It seems to be a standstill at this point."

"Basically," he argues, "politicians are afraid. They are living on two-year life cycles, four-year life cycles." For leaders worrying about re-election, raising taxes for infrastructure improvements is simply not an option.

"Getting them to actually make the investment and realize that they'll save money by making the investments, that's the hard part," he says. "That's why we're trying to educate the public. They're the ones that elect them. When a politician says, 'I can't raise the gas tax because I won't get re-elected,' if the public starts saying, 'I want these better things, and you're going to have to do something,' maybe things will start changing."

This kind of public awareness is critical for change, he says. To keep U.S. manufacturing growing, the nation must bring infrastructure back to the forefront to help make these investments make sense in our difficult economic environments. Revitalizing the infrastructure means getting projects through and matching new technologies with a well-maintained system.

As Herrmann explains, "By making investments, you are actually saving money. You're saving sitting in traffic, you're saving brownouts, you're saving loss of jobs and costs to the gross domestic product and industry. These are things that are going to be coming up. If you make the investment, you're going to be saving dollars."

Things to Think About and Do in 2012: Standards


Below is an excerpt from ReliabilityWeb.com's E-Book: Things to Think About and Do in 2012.

Standards

When faced with problems, we often go into root cause analysis (RCA) mode trying to find the single cause of the problem. However, problems are often the result of multiple causes. In total productive maintenance (TPM), we identify chronic deterioration that eventually combines to cause sporadic failures.

A different approach is to ask a simple question: Do we have a standard If we don’t have a standard, the appropriate response is to create one. Let’s define a standard as a reliable method that produces the required output from given inputs.

I have been working recently with a beverage can profucer with high speed automated production lines but very variable levels of defects. The RCA approach was not generating sustainable improvements because no on knew why defects were high in one batch and low in another, with multiple causal factors. Our approach, therefore, was to identify the key process parameters and record them for a “good” batch, and when defects arose, return the process to the standard parameters of the good batch. After we identified which parameters had slipped, we can then use reliability engineering ot TPM approaches to prevent them from deteriorating in the future.

Even if we have a standard, there are more questions to be answered:
  • Have we communicated the standard effectively?
  • Have we trained people in the standard adequately?
  • Are people using the standard consistently?
Only if we can answer all these questions positively should we then ask:
  • Is the standard a reliable method?
  • In other words, is the process capable?
So my thing to think about and do in 2012 is: When faced with a problem, ask yourself, “Do we have a standard?” The answer may surprise you.

Predictive Maintenance Survey Reveals Drivers, Obstacles and the Future

Financial Considerations Propel the Use of Oil Analysis, Infrared, and Vibration Testing


In brief:
  • PdM is the practice applying condition-based monitoring techniques to collect and analyze asset data to gain an understanding of asset performance and perform appropriate maintenance as indicated by the asset.
  • In order for production to meet targets, equipment must be available and in acceptable working order.
  • Efficient management of assets is critical to improving plant performance.
The global process industries lose an estimated $20 billion annually due to unscheduled downtime and poor quality. It’s no surprise that, in a joint survey by Plant Services and ARC Advisory Group, respondents indicated "improve uptime" as the primary driver for deploying predictive maintenance (PdM) solutions (Figure 1). PdM is the practice applying condition-based monitoring techniques to collect and analyze asset data to gain an understanding of asset performance and perform appropriate maintenance as indicated by the asset. The survey polled end users regarding current status of PdM programs, as well as future plans for improvement.

Figure 1. Almost 90% of survey respondents deploy PdM solutions to improve uptime.
Figure 1. Almost 90% of survey respondents deploy PdM solutions to improve uptime.

This PdM survey provides insights on practices and maintenance management. Users should compare their operations with the survey results to gain a better understanding of best practices and obtain ideas for proven improvements.

In order for production to meet targets, equipment must be available and in acceptable working order. Ineffective maintenance accounts for $60 billion annually, according to ARC research. This PdM survey reflected that manufacturers are well aware of this, too, as "reduce operational cost” was the runner-up, followed closely by "reduce maintenance cost". A sound PdM strategy can improve workforce and financial performance. With a combined view of asset availability and other operational constraints, workers can make information-driven decisions.

PdM technology usage
PdM is frequently referred to as condition-based maintenance, but, regardless of what it’s called, these types of solutions quantitatively evaluate equipment condition relative to an established baseline or standard. The value of PdM lies in its diagnostic capabilities, which greatly aid in the maintenance decision-making process. Spending for PdM systems continues to outpace that of the automation industry in general, as manufacturers seek to leverage a deeper knowledge of equipment condition as a means of increasing asset utilization and productivity and reducing maintenance costs, according to ARC research.

The increased amount and complexity of automation equipment currently installed in plants requires a higher-order approach to maintenance provided by PdM systems. As the discipline of asset performance management (APM) matures, the process industries are exhibiting a greater understanding of its principles. As users become more familiar and proficient in condition-based monitoring techniques, they will demand more from the equipment, and suppliers must keep pace.

Figure 2. More than two-thirds of survey respondents use oil analysis, infrared, and vibration testing as part of their PdM practices.
Figure 2. More than two-thirds of survey respondents use oil analysis, infrared, and vibration testing as part of their PdM practices.

The survey results indicate that oil analysis, infrared, and vibration are widely implemented now (Figure 2). Predictive monitoring solutions continue to expand in capability, as indicated by the interest in corrosion monitoring. The effects of corrosion cost the process industries roughly $300 billion annually in lost production, failure of key equipment, and fines for environmental and safety violations. Corrosion monitoring can significantly lengthen the life of mechanical equipment and piping, as well as prevent abnormal situations from occurring. In addition to traditional PdM technologies, reliability, predictive software modeling, and condition monitoring in EAM/CMMS were included as choices for survey respondents. Responses for reliability and CM in EAM/CMMS were very similar. However, it appears that utilization of predictive modeling as a PdM technology is not yet mainstream.

Integration enhances value of PdM
Stand-alone solutions can provide excellent value for newcomers, but may not be sufficient for sustainable improvement due in part to the islands of information stand-alone solutions create. The industry has progressed far beyond proprietary one-off connectors to certified interfaces to facilitate information exchange. In organizations where increasing physical asset reliability as a means to improve asset availability is deemed the primary goal, connecting PdM applications that directly or indirectly administrate, measure, analyze, resolve, and improve asset performance in a comprehensive fashion will drive appropriate workforce actions. The good news is that, for the most part, survey respondents are integrating PdM solutions with other enterprise systems, particularly with historians and EAM/CMMS (Figure 3).

Figure 3. Almost half of survey respondents indicate they use an historian for collected data.

The current generation of plant equipment is far more intelligent than previous generations. These more intelligent assets require a more strategic, integrated management approach. Leveraging the rich information in these solutions can improve the effectiveness of each. Ideally, all solutions should be connected in real time. Integrating solutions based on function offers a practical approach. For example, PdM and EAM systems have embedded ready-made networks for the collection of disparate data. Combining reliability information with PdM solutions can improve the predictive capability of the PdM solution by identifying assets for critical assessment and thereby minimize the possibility of asset failure.

Survey respondents are integrating PdM with historians most frequently. However, what is not clear from the survey is if the historian is being utilized as a data archive, as has been the case traditionally, or as an improvement tool. With increased data throughput and higher data resolutions, historians have evolved to become a tool for managing plant assets, thanks to new visibility and trending tools. Today's historians also support techniques, such as complex event processing, which can analyze multiple streams of plant data in real time to identify and diagnose emerging problems before disrupting production. Remote access to historian data via the Web enables central management of assets, whether within a single plant or across multiple plants. PdM solutions are widely integrated with EAM/CMMS, according to the survey. EAM systems have also evolved to include greater functionality to accommodate the broad spectrum of features needed to effectively integrate and manage the different types of asset classes found throughout the enterprise. New EAM systems configured to support the maintenance business processes of an enterprise can integrate, consolidate and help prioritize data for a single version of the truth throughout the enterprise. Features such as real-time data collection, diagnostics, and analysis tools enable individual users to prioritize and track information in the context of their functions.

Equally important is integrating applications using standardized formats that permit the enterprise to undertake corporate-wide initiatives. Additional value is derived from the sharing of best practices among individual plants for continuous improvement throughout the organization. From a management perspective, the addition of risk and simulation functionality provides management with deeper insight into the financial implications of PdM before making a decision to adjust resources.

Recommendations.
Efficient management of assets is critical to improving plant performance. As a component of a comprehensive asset performance management strategy, PdM solutions offer huge benefits. However, the value realized by the enterprise is dependent upon selecting solutions that fill gaps in existing practices. Companies that adopt a strategic approach to plant assets and their management will drive the enterprise to optimal performance.
  • Investigate PdM solutions and adopt those that support core objectives and goals of the enterprise. Include estimations for implementation cost and schedule, including implementation resources, regulatory requirements, the type and version of applications and systems, proprietary data sources, and types of processes that will be impacted.
  • Invest in PdM solutions with real-time analytics functionality that provides the ability to perform dynamic or real-time calculations and to compare current and historical data.
  • For beginners, consider implementing PdM solutions in a pilot project in one location. Measuring and quantifying the benefits realized will help build the case for future PdM deployments.
  • Consider PdM solutions that express information in financial terms that can be directly correlated to recommended actions or that clearly show the cost of inaction. In some organizations, it might be possible to tie actions to financial incentives. Incentivized workers have a way of being successful, provided the goal is achievable and can be accurately measured.
  • Integration remains a challenge for most enterprises, but the ability to easily integrate multiple applications is key for successful PdM implementations. Integrating allows the workforce to gain additional insight to optimize asset availability and utilization while balancing operational constraints to improve financial results.
