MAINTENANCE BEST PRACTICE

Most organizations focus more on cutting maintenance

costs, and, as a consequence, maintenance costs go down

temporarily, only to increase much more than the initial savings.

In addition, reliability goes down, paving the way for losses that

can be substantial. This behavior and results have been proven

many times, especially in economic downturns. The root cause

of this phenomenon is often shortsightedness and what the late

quality leader Dr. W. Edwards Deming described as one of the

most serious diseases in American industry: “the mobility of top

management.”

The three case studies that follow demonstrate what happened

in two organizations that focused on cost reductions and in a

third organization that focused on Results Oriented Maintenance.

RELIABILITY IMPROVEMENTS DRIVE DOWN MAINTENANCE COSTS

An organization must focus on sustainable results, not just cutting costs. Three case studies illustrate.Results-oriented organizations focus first on the quality and volume of production throughput, followed closely by the cost to produce the required quality and volume. This approach will improve reliability performance, which will drive manufacturing costs down.

Case 1: Cost and head count reduction

Case 2: Aggressive cost reduction

The accompanying graph shows a 3-year case study in a food

processing organization with an aggressive cost reduction

program. A key measure used in maintenance benchmarking

exercises was the number of maintenance crafts people and first

line managers such as planners and supervisors.

The head count reduction was done through attrition and layoffs.

The major mistakes by this organization were:

• To cut costs by reducing only the number of employees

and not considering reducing the need for maintenance or

improving work processes.

• To focus on number of employees, instead of hours of

maintenance work, including overtime and contractor

hours. Case 2: Aggressive cost reduction

The graph for this case shows results at a chemical plant, a

high-cost producer in its market, where management decided to

do whatever it took to cut costs, mainly in maintenance. When

the cost-saving initiative started, market prices for the plant’s

products were low and profitability in a short-term perspective

was low compared to other plants in the corporation. The fast-

paced cost reduction actions included:

• Operations took over maintenance and only did

maintenance work that was judged absolutely necessary.

• Planners were laid off and planning of work was

discontinued.

• Scheduling was discontinued.

• Maintenance prevention activities such as shaft alignment

were abandoned and lubrication was handed over to

operators without training and implementation of a

documented program.

• he preventive maintenance program was handed over to

the operators, without training in what to do or how to

inspect. The preventive maintenance inspectors were laid

off.

• Shutdown crews were merged with another plant about 1

hr drive from the subject plant.

• Painting programs were abandoned.

• Training of crafts people was discontinued.

After realizing the catastrophic consequences of what had

happened, the mill took initiatives to bring maintenance to

world-class status. Results are very encouraging and the mill

is today one of the top performers. Reliability is approaching

94 percent. Maintenance costs have gone up, so has quality

production throughput, and manufacturing and maintenance

costs per ton are lower.

The actions taken to bring maintenance to world-class

status included:

• Reinstating preventive maintenance inspectors and revising

the preventive maintenance program.

• Bringing maintenance back to a central maintenance

function.

• Developing a partnership between maintenance and

operations instead of a customer-supplier relationship.

Page 6: EMS June 2011

MAINTENANCE BEST PRACTICE

Case 3: Reliability improvements first, costs second

• Focusing on planning and scheduling and front line

implementation of these practices.

• Developing employees’ capabilities toward joint goals.

• Making capital investments in new equipment and

restoration of worn out equipment.

• Implementing front line management action indicators.

This plant manufactures the same product as the plant described

in the previous case, but it decided to focus on reliability

improvements instead of only cost reduction. This included:

• A clearly outspoken and established partnership between

operations, engineering, and maintenance was forged.

• A change was made from a reactive to a planned and

scheduled maintenance organization. Less than 10 percent

of all maintenance work was planned when the initiative

was launched. Ten years later more than 85 percent of all

work is planned and scheduled.

• A strong vibration analysis program was implemented.

When it started, the average vibration level was 0.23 in./

sec. Today it is down to 0.11 in./sec.

• Lubricators were professionally trained. This resulted in

better filtration and water removal, better seals, oil testing,

and fewer types of lubricants. Cost for lubrication was

reduced by 60 percent.

• All rotating equipment above 1000 rpm is balanced

dynamically before it is put into service.

• Many equipment bases were improved and equipped with

jack-bolts to improve alignment precision.

• Electric motors and rolls in storage are marked and rotated

twice a month.

• Alignment training, standards, and execution were

implemented.

• Stores inventory and services were analyzed and improved.

Service level now stands at 96 percent and stores value has

been reduced by more than 30 percent.

• Adherence to preventive maintenance schedules was

increased to over 90 percent.

Reliability pays

Reliability improvements increase production

throughput and drive down maintenance costs.

Maintenance cost reduction is a consequence

of reliability performance; it is never the other

way around.

The number of crafts people was

reduced by 14.3 percent the first year.

After 1 year, 6 percent were hired back.

In the same period, contractor spending

went up 88 percent. Total maintenance

hours including overtime, contractor

hours, and in-house hours went up

10.5 percent. Total maintenance costs

went up 29.2 percent. On top of that,

reliability and production throughput

decreased 6 percent. This plant is now

investing in hiring and training more

maintenance people, implementing lost

maintenance practices, and moving

all maintenance resources back to

professional maintenance management

after initially decentralizing maintenance

to operations.

Case 1: Moving maintenance resources to operations and cutting craft personnel

Page 7: EMS June 2011

7engineeringmaintenance.infoJune/July 2011

MAINTENANCE BEST PRACTICE

In the first 2 to 3 years maintenance costs dropped from $35 million/yr to $27 million/yr and results were hailed as good. However, reliability started to decline. When beginning this initiative, overall production reliability (OPR)—the product of quality performance, time performance, and speed performance—was 93 percent; it bottomed at 78 percent 6 years after the start of the initiative. At this time the market price for the plant’s products had doubled. The drop of 15 percent in OPR and quality production output corresponded to a loss of over 300,000 tons during some very good years when product could be sold at top prices. Financial losses because of low OPR resulting from shortsighted maintenance cost savings are conservatively estimated to exceed $1.2 billion over a 3-yr period.

During the first 3 years, maintenance costs increased 8 percent (2.5 to 3 percent/yr). During the same period, reliability as measured by OPR, and consequently also production throughput, increased steadily from a low of 83 percent to 90 percent. Reliability continued to increase to 92 percent. In financial terms, a short-term increase in maintenance costs of about $3.3 million resulted in savings of $17 million annually. The value of increased and sold production represented $18 million annually. Total maintenance costs were reduced by 40 percent. Today this plant survives another economic downturn because of the reliability initiative it initiated and implemented.

Case 3: Focus on reliability

ENSURE RELIABLE GAS DETECTION WITH NEW DRAEGER WIRELESS SAFETY NET

For further information contact:

Customer Service, Draeger Safety UK Limited,

Ullswater Close, Blyth Riverside Business Park,

Operating as an all-round safety network, the new Draeger X-zone 5000 uses wireless technology to automatically connect multiple monitors for reliable, continuous detection of toxic, combustible and explosive gases.

Ensuring that personnel have the confidence to work worry free, even in the most dangerous environments, these transportable units are quick to deploy and easy to set up. Issuing a loud alarm as soon as a gas is detected, they also change colour to clearly identify the alarm status. The areas where gas has been detected are indicated by red visual alarms. Safe atmospheres and, therefore, a safe escape route are confirmed by green visual alarms.

By simply placing Draeger X-zone 5000 units around potentially dangerous areas or where maintenance or shutdown work is being carried out, these robust, waterproof units will ensure increased levels of safety in any application. As soon as one of the units detects a gas it immediately transmits an alarm to each of the others, warning everyone in the area that a danger exists. At the same time, a loud evacuation alarm is emitted and a patented 360º alarm amplifier ensures that it is heard with the same intensity in all directions.

Up to 25 Draeger X-zones can be used at any one time, forming a complete wireless network to suit the specific application, including those where an explosion hazard might exist. In addition to Zone 0 ATEX performance, they also offer a lower cost of ownership by combining flexible monitoring capabilities with a long sensor life and enhanced battery performance.

Allowing gas ingress from every side, it can be fitted with up to four sensors to detect as many as five gases at once. The Drager X-zone 5000 provides simultaneous measurement of gases and vapours such as hydrocarbons, hydrogen and other explosive, combustible or toxic gases.

Unlike portable instruments which usually leave the scene with the wearer, the Draeger X-zone 5000 can be left in situ for up to 120 hours continuous operation, issuing an alarm as long as the danger exists.

The installation of a new ABB WaterMaster electromagnetic flowmeter is helping energy company RWE npower fulfill its MCERTS commitment. The 1,400MW power station, based in Didcot, Oxfordshire, has always monitored the amount of cooling water that it discharges from the site, but this extra tier of instrumentation will enable it to verify that the readings provided by the existing meters are accurate. “We’ve already got three meters on our cooling water purge system but we’d like to be able to verify their performance,” says Peter Harrison, Senior C&I Engineer. “We’re now installing an MCERTified WaterMaster electromagnetic meter from ABB at a point where all three flows come together. This means we can verify the readings from the other three meters, in addition to verifying the WaterMaster itself, insitu using the WaterMaster’s onboard verification system.” Launched in 2008, the WaterMaster was one of the first flowmeters to be awarded a Class 1 MCERTS conformity certificate for closed pipe flow measurement. MCERTS is the Environment Agency’s certification scheme to ensure that companies have effective measures in place to monitor their effluent flow. Industrial sites need to meet MCERTS requirements whenever their discharges must be monitored and controlled as part of their permits under the Environmental Permitting Regulations (EPR). Civil works are about to begin on the installation and the new, two-tier system should be up and running later this year. “I’ve used ABB flowmeters before in my previous work and I’ve always found that they perform well. I like to think this one will provide the same great performance,” says Mr. Harrison. RWE npower is also taking the opportunity to upgrade its data logging facilities with the addition of a ScreenMaster videographic recorder from ABB. ABB can also provide additional support in the form of annual verification services, including verification of installed WaterMasters utilising VeriMaster verification tools. This can assist with demonstrating an ongoing robust metering regime in preparation for possible quality management system (QMS) audits in the future.MCERTS and the self-monitoring of effluent flow is just part of a wider philosophy within the Environment Agency to promote “better regulation”. This means encouraging companies to

comply with and even exceed legal requirements without constant supervision. “MCERTS is all about helping to protect the environment through more accurate monitoring and collection of data relating to emissions to air and discharges to water,” says Tony Hoyle, General Manager for ABB’s UK and Ireland Measurement Products business. “ABB has long been a supporter of the MCERTS scheme, having achieved the first ever MCERTS product approval certificate for its ZFG2/ZDT zirconia oxygen analyser system in 1999. We followed this tradition by making our WaterMaster flowmeter one of the first to beMCERTified for closed pipe flow measurements.” ABB has released a comprehensive new guide to the Environmental Permitting Regulations (EPR) and MCERTS, the Monitoring Certification Scheme of the Environment Agency (EA). Entitled MCERTS and EPR – a guide to environmental EPR legislation and monitoring systems and services, the guide is a useful point of reference for anyone responsible for the monitoring of emissions to air or water at an EPR regulated site.

“We reviewed operations carefully and have now successfully integrated customer service, aftersales and project sales,” said Mark Hodgens, Managing Director. “Combining as a single business is an important milestone, our customers and suppliers will be receiving formal communication over the coming weeks.”

Although Nederman have completed several notable acquisitions, both in the UK and internationally, following successful flotation on the OMX Stockholm Stock Exchange in 2007 this has been on a different scale, doubling Nederman’s size and positioning it as the global market leader in industrial air filtration. The group now makes combined annual sales of around £195 million in nearly 60 countries (with 27 fully owned companies) supported by manufacturing and assembly plant in 8 countries.

Whilst Dantherm and Nederman have overlapped in the market, the systems are really complementary. Nederman’s industrial air cleaning systems typically run to 15,000 m3 where Dantherm’s reach 150,000 m3 and cover specialist market segments including foundries, smelters and wood dust.

“In reality, many of our customers need a mix of systems,” said Mark Hodgens. “The overall expertise in industrial air cleaning is impressive, we can now meet the market with a broader and more complex product range.”

NEDERMAN AND DANTHERM FILTRATION COMBINE IN THE UK

KABELSCHLEPP ON UK MANUFACTURING AND THE HANOVER FAIR 2011

Following last year’s acquisition of Dantherm Filtration by Nederman, the combined business began trading in the UK as Nederman Ltd on 01st April 2011.

Further information is available on request from Nederman by contacting 08452 743434 or at www.nederman.co.uk .

One plus one equals more than two, that´s how you could draw a balance after a year of collaboration between KABELSCHLEPP and the Tsubaki Group. Things have been happening in more areas than just the product range. The worldwide presence and customer service were also intensively expanded.

Along with the sales and on-site service, the product program was also expanded. For example, in the universally applicable UNIFLEX Advanced plastic chain series, the type series 1665 with an inside height of 44 mm is now available in an additional inside width: 200 mm. That makes eight widths in total, covering measurements from 50 to 250 mm. Type series 1320 was also expanded; an inside width of 50 mm is now available, as well as models with new bending radii of 38 and 48 mm. The weight-optimised cable carriers in this series are well-suited for a broad range of applications. They are equipped with internal sound dampening for an especially quiet run and offer numerous possibilities for interior partitioning. An aluminium tray system is now available for the type series 1555 for vertical, hanging applications Amongst its many applications, it is suitable for use in fast-moving storage and retrieval machines with high lateral acceleration and is available as a complete system, ready for installation and connection, including carrier stop, cables and tension relief. The modular construction makes it especially easy to install. Standardised dimensions and basic components result in short delivery times and custom-modification for affordable solutions.

The sensor makes fluidic systems more reliable by enabling the detection of liquid flow within the range of a few ml/min and less. For such measurements the sensor offers a short response time below 100 ms. Its output signal of either 0 or 5 volts indicates whether the current flow rate is above or below the specified flow switch level. At continuous flow rates above this limit the identification of air bubbles within the flow channel is equally consistent. Maximum flow rates are accepted up to 220 ml/min. Fluidic connections can be made via 1⁄4-28 standard fittings, suitable for connecting plastic tubing with outer diameters of 1/8” (3.2 mm) or 1/6” (1.6 mm). Barb connector adap- ters are available as an alternative.The tiny, light sensor is designed for integration into bio-medical applications and general process control solutions. An ex- cellent chemical resistance and bio-compatibility are ensured by its non-invasive measurement through the wall of the straight, internal glass capillary (diameter 1.8 mm) and fluidic connectors made of PEEKTM high-end plastics. The new prod- uct is based on a digital MEMS chip and expands Sensirion’s existing line of high-quality liquid flow products by employing a simple and cost-efficient solution.

ENERGY MANAGEMENT

Prior to the installation of the GEM® steam traps, the mechanical traps regularly failed open, closed or partly open, necessitating regular replacement and maintenance. It was calculated that due to trap failure ELANTAS Deatech was wasting a large proportion of its steam production, which in turn was increasing energy costs.

Thermal Energy International organised a bucket test to measure the live steam loss through the trap at various condensate load conditions. This proved that the GEM® technology was significantly more efficient over varying loads.

ELANTAS ENJOYS SIGNIFICANT STEAM SAVINGS WITH GEM®

“Thermal Energy International has supported the project throughout with a survey of the steam traps, a payback report and bucket test”, says Mr Giorgio Monni, Plant Manager at ELANTAS Deatech’s Ascoli Piceno plant. “The GEM® venturi steam system has provided us with real savings and the prospect of a large reduction in maintenance costs”.

Such has been the success of the GEM® technology at the Ascoli Piceno site that Thermal Energy International received an additional order for GEM® steam traps for the company’s site in China and this year received a further order for GEM® traps for the Ascoli Piceno plant.

Available in a wide range of sizes for a full cross section of applications, the hardwearing GEM® steam traps are manufactured from corrosion resistant stainless steel and are guaranteed for 10 years, eliminating the need for repair or replacement. The GEM® steam traps can provide a fast payback from reduced energy costs and increased equipment reliability. In addition it can improve product processing by enhancing process control, and can also reduce equipment repairs, downtime and replacement costs.

ELANTAS Deatech S.r.l, a member of

the global specialty chemical group

Altana AG, and a leading producer of

insulating materials for the electrical and

electronics industry, has revealed that it

is achieving significant savings in steam

consumption at its site in Ascoli Piceno,

Italy following the installation of Thermal

Energy International’s GEM® steam traps.

ELANTAS Deatech has now replaced all of

the mechanical steam traps on its process,

utilities and steam distribution pipeline

with the GEM® venturi orifice design.

PAPER MILL BOOSTS RCM PROGRAM WITH COST SAVINGS GENERATED BY ITS IR WINDOW PROGRAM

Overview:

A paper mill in Georgia had run a very successful infrared

inspection program for a number of years using a local,

contract thermographer working with the mill’s in-house

electricians. Although the program had a good track

record, senior management was concerned about the

potential impact of NFPA 70E requirements, and how

best to comply with them. The plant commissioned IRISS

Inc. to conduct a cost-benefit analysis -- and present its

recommendations.

Analysis of Inspection Program:The annual infrared surveys focused on the power distribution equipment as detailed in Table 1.

Electrician Waiting Time 93.2

Thermographer Waiting Time 186.4

Total Billable Man-Hours 787.0

Unproductive Man-Hours 367.6

Twelve of the 27 pieces of 13.8kV primary switchgear were not included in the inspection due to the presence of switched interlocks (which automatically de-energize the gear upon opening). In addition, the thermographer was unable to inspect eight HV (High-Voltage) transformer cable compartments under load due to the energized work restrictions implemented by the plant safety manager. The review showed that 11% of the plant’s critical assets were never inspected during the annual survey.

A time study was completed detailing the man-hours and the costs involved in completing the annual IR inspection based on NFPA and OSHA safety mandates.

Cost Analysis of Traditional Inspection:The client had been using a contract thermography company for more than seven years, and was very happy with the service. The IR survey crew consisted of two in-house electricians and one contact thermographer. The hourly wrench time (time spent on productive labor) rate for the electrician was calculated at $68, and the contract thermographer’s rate was $150 per hour ($1,200 a day). Traditionally, the whole inspection required 29 days to complete. This translated into 787 billable hours (as seen in Table 2).

The entire inspection team dressed in 40 Cal/cm2 PPE (personal protective equipment) in accordance with NFPA 70E and OSHA

mandates for energized work. They spent on average 30 minutes to suit-up and dress-down -- twice a day. This was a total of 88 hours related to PPE over a 29-day cycle. The thermographer spent 186.4 hours waiting for panel covers to be opened/closed to provide him with access. Similarly, the electricians spent 93.2 hours (46.6 hours x two men) waiting for the thermographer to complete his work once the panels were removed.

After analyzing the time studies, facility management was surprised to learn that a staggering 367.6 hours (46.7%) of the total project time for the traditional open-panel surveys was non-productive (PPE suit-up, thermographer wait-time, electrician wait-time, etc.). A task breakdown is shown in Table 2.

Table 3 details the man-hour costs for the infrared survey using a contract thermographer without infrared windows or viewports. The following assumptions are made:• Total man-hours per inspection of “inspectable” equipment:

787 hours (29 days)• Staff electrician internal charge-out rate $68 per hour• Contract thermographer charge-out rate $150 per hour• PPE suit-up twice daily, per man (30 minutes per man, per

suit-up)• 48 minutes per compartment panel for safe removal,

refitting, (per man for a two-man team)• 12 minutes per panel for infrared scan.• 233 individual panels to inspect (Table 2)

PPE Suit-up Time 88 $8,324

Total $74,919

Infrared Windows:In search for an alternative approach that was both safer and standards-compliant, the corporate reliability engineer investigated how infrared inspection windows (commonly referred to as IR windows, viewports or sight glasses) might be utilized. It was determined that:• Use of IR windows 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.

• Use of IR windows or “sightglasses” would eliminate the

Investment:The facility’s 179 applications with 263 inspection compartments required 312 infrared inspection windows (Table 4) in various sizes:

143 units, two-inch diameter (VPFR-50)107 units, three-inch diameter (VPFR-75)62 units, four-inch diameter (VPFR-100)

The 312 windows represented an investment of $51,405.00. IRISS, inc. also provided a cost-benefit analysis comparing in-house installation versus out-sourced.

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.

• Use of IR windows and closed-panel inspection would eliminate high-risk tasks during inspections -- increasing safety for thermographers.

• Use of infrared 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.”

• In NFPA terms, an IR window maintains electrical equipment in an “enclosed” state and it maintains energized components and circuit parts in a “guarded” condition. Therefore, the hazard/risk category would be equivalent to reading a panel meter, using a visual inspection pane for lockout/tag-out confirmation, or walking past enclosed, energized equipment.

• Use of infrared windows would improve inspection efficiency. It would allow increases in inspection frequency for those mission critical or suspect applications.

Out-sourced installation (Table 5) was based on the following assumptions: • A two-man installation team can comfortably install 40

inspection windows in one shift• 312 infrared inspection windows would require eight shifts

to install completely (shutdowns permitting)• The cost of the contract installation team was calculated

as follows: eight days at $625 per man, per day (total cost $1,300 per day) for a total of $10,400

• Installer would charge a flat $30 fee per window -- in addition to the daily rate ( 312 windows x $30 = $9,360)

• Total installation charge: $19,760

In-house costs (Table 6) were calculated using the following assumptions: • A two-man team can comfortably install 40 inspection

windows per shift• 312 infrared windows would require eight shifts, or 128

man-hours, to install• The complete project could be managed around shutdowns• In-house team costs were calculated as follows: 128 man-

hours at $68 per man/per day for a total cost of $8,893• No additional charge incurred per windowClient would retain IRISS for a day of on-site installation training at $995The client decided to use in-house manpower for the installation due to the savings. The Jumpstart Installation training was scheduled for the first day of the shutdown so the in-house electrical staff could be properly trained.

Total savings to the customer by adopting an in-house install program were $9,872.00 -- almost a 14% savings over an out-sourced installation team.

Total Cost of Inspection Using IR Windows

Inspection Time 53 $7,950

The Installation:The installation of the inspection panes was conducted during a seven-day 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”. However, some installations 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. The plan called for two teams working a twelve-hour shifts. Installers were quickly and safely working at a rate of approximately six windows per hour. As they progressed through the learning curve, the teams became more proficient, hitting an install rate of seven to eight windows per hour (versus the budgeted five per hour).

Cost Analysis with Windows:With the infrared windows installed, there was no requirement to remove panels or wear increased levels of PPE. In addition, inspections were now performed on the 11% their applications that had previously been considered “uninspectable”. Finally, the entire task became a one-man job.

The windows also increased efficiency and economy-of-motion. Total man-hours to complete an inspection dropped to just 53. As a result, the new survey dropped from almost $75,000 to just under $8,000 (as detailed in Table 7). Because of the efficiencies achieved, the mill saves $68,964 per inspection -- a 92% savings.

ROI:Table 8 combines the data from the previous tables to illustrate the ROI (return on investment) that the mill realized from its infrared window program. The table details the total investment using three scenarios: 1) traditional open-panel inspections with a contract thermographer and two staff electricians; 2) the same contractor using infrared windows; and 3) an in-house thermographer using infrared inspection windows. It then compares the ROI that the mill was able to achieve using windows and either a contract or in-house thermographer.

Switching to infrared windows is shown to pay dividends in just one inspection cycle. Over $5,600 in savings can be put back into the budget by the end of the first cycle. After just five inspection cycles, the mill shows a savings of over $273,542.

Plant management was encouraged by these projections, so they decided to invest in an infrared camera and training for two of its engineers (one electrical and one mechanical). Two engineers were enrolled in a Level I thermography course at $1,250 per man. An additional $1,500 per man was budgeted for travel and expenses. The new camera totaled $8,000. The total investment to start up the new internal inspection team was $13,500.The cost of in-house inspection (47 hours x $68.00) amounted to $3,196 per inspection, yielding a savings of $3,794 per inspection (or 54%) compared to a contractor.

ROI of the new program using internal resources was achieved within the second inspection cycle; by the fifth cycle, the ROI was over $280,000.

Because inspections can now be completed with greater ease and without increased risk to plant, personnel and processes, the mill increased the frequency to quarterly, reflecting best-practice recommendations that originally were not considered feasible.

Conclusion: The new inspection process using infrared windows brought

significant ROI to the plant in just one quarter, while reducing

the risk of catastrophic failure among the plant’s critical power

distribution systems.

Management succeeded in:

• Increasing safety

• Facilitating inspections of previously “uninspectable”

equipment (11% of critical assets were not inspected in the

old program)

• Increasing the frequency of inspection -- while saving

money

• Safeguarding profitability by eliminating high-risk behavior

that posed a risk to plant assets and production

The purchase of the IR camera and training for the maintenance

engineers quickly paid dividends. It allowed the plant to improve

the maintenance program while operating in full compliance with

the requirements of NFPA and OSHA.

An infrared window program provides a cost-effective and safer

alternative to traditional open-panel inspections. To learn more,

PRODUCT SPOTLIGHT - DRY LUBRICATION

PRODUCT SPOTLIGHT - VIBRATION MONITORING

At MillerCoors, water is everything. From brewing to pasteurizing to shipping, water is essential to run the factories. “It’s the main ingredient in our beer. It helps clean our brew kettles. It helps water our crops,” states Kim Marotta, Vice President of Corporate Social Responsibility for the company. As part of its environmental commitment the company is determined to reduce its water usage without impacting on its products. In order to create “America’s Best Beer Company” MillerCoors wants to “grow its business the right way”. One initiative is to move away from wet lube!Converting many of its lines to dry lubrication is to be a significant contributor in the company’s 2015 water goal of reducing its water usage by 15%.

For example, in the Fort Worth brewery 9 out of 10 lines are converted to Dry Lube. The brewery is now on target to save 9 Million gallons of water a year. By using 3.40 barrels per barrel of beer produced, Fort Worth uses the least water across the eight Miller Coors breweries. It is also the third-lowest water consumers within its parent company, SAB Miller, with 77 large breweries worldwide. Dry Lube Ltd is proud to have helped MillerCoors reach this standard and is positive it can continue this excellent relationship; to save more by using less.

SAVING MORE BY USING LESS MILLERCOORS TO MOVE AWAY FROM WET LUBE.

It can take as much as eight pints of water to produce one pint of beer. High water and sewerage prices as well as greater environmental awareness have increasingly put brewing under pressure to improve its sustainable performance and in particular its use of water, energy and transportation.

Vibration modules are a cost effective solution for monitoring the condition of industrial machinery giving the facility to provide multiple outputs, for example, RMS velocity, enveloped or peak ‘g’, 0-10V, 4-20mA and buffered acceleration. They introduce additional signals which can be scaled to suit the specific application in order to achieve the best results.

Popular models in the range include the HS-530 and HS-535 which are DIN rail mounted, offer a choice of triple or quad output and require a 24 V DC supply.

The range of vibration modules provide flexibility with input - 100mV/g from a constant current accelerometer operating over a typical frequency range from 2Hz up to 10kHz. Filters are also included for gE, g pk-pk and velocity, depending on the required model. Select modules are available with a BNC so any

commercially available data collector can be inserted to retrieve signals for data analysis.

MACHINE SAFETY

Designers of plant and machinery are normally responsible for implementing the safety-related requirements and for selecting the components used for safe monitoring. However, designers are spoilt for choice, which makes choosing the most appropriate safe sensor or actuator/sensor combination a difficult task.

Sensor systems operate using different principles and so it is important that designers fully understand the implications of using each type. The challenge is to try to harmonise productivity with machine safety and user-friendliness. If a safeguard is not user-friendly, there may be a temptation to manipulate a safety guard, putting the machine operator at risk. Designers need to identify potential cases in which safety devices might be manipulated and then to eliminate these at the machine development stage.

Certain considerations will help the designer to decide which components should be used for the safe monitoring of movable guards in accordance with EN 60947-5-3. Typical questions that should be asked include: is the cover frequently opened and closed? Does the process need protecting as well as the operator? Are components exposed to high vibration or extreme temperatures, or are they used in potentially explosive areas?

Mechanical safety switchesFor simple safety gate applications where there is no increased risk of manipulation, mechanical

HARMONISING PRODUCTIVITY WITH MACHINE SAFETYSafety gates, protective covers and

machine guards prevent hazards

associated with moving parts.

However, the correct functioning of

a safeguard can only be guaranteed

by using the appropriate sensor

technology. Alex Bryce, Sales

Manager at Pilz Automation

Technology, considers the sensor

systems currently available and

the selection criteria that designers

should consider.

safety gate switches are widely used. These are used for simple safety gate monitoring or with a mechanical guard locking device, which uses increased extraction force on the actuator to prevent the gate or cover from being opened unintentionally. Many applications require two mechanical switches to guarantee the required level of safety, which increases engineering costs significantly.

Another consideration here is that swarf can quickly be deposited on the sensor, restricting its function. Also, if safety gates drop over the course of time, the lifetime of a mechanical switch is reduced considerably.

Mechanical safety bolts are complete solutions comprising a safety switch, handle and bolt. These provide protection where safety gates are difficult to adjust, as well as on safety gates that are frequently opened and closed. A mechanical guide on the actuator ensures that the actuator engages with the safety switch correctly when the safeguard is closed.

Mechanical hinge switches provide an elegant solution for rotating or hinged gates and flaps. These provide better protection against manipulation compared to other mechanical solutions because they are concealed within the hinge, which also saves on installation space.

Non-contact safety switchesGates, covers and flaps often need to be opened repeatedly for operational or assembly purposes, to enable operators to access or reach into the protected area.

Page 37: EMS June 2011

37engineeringmaintenance.infoJune/July 2011

MACHINE SAFETY

Here, the risk of a gate being mechanically misaligned is high.

The disadvantage of mechanical guard locking devices is that they only have limited tolerance for misaligned gates. For this reason, non-contact safety switches provide an attractive alternative, particularly if there are high vibrations. These switches have a higher response tolerance, allowing greater flexibility in the way they are attached to the machine.

Rugged non-contact switches are also suitable for applications that require protection types higher than IP67. These switches are able to meet safety requirements up to PLe of EN ISO 13849-1, and SIL 3 of EN/IEC 62061, or Category 4 of EN 954-1.

When it comes to deciding on the acting principle of the sensor, important distinctions need to be made. Whilst magnetic safety switches provide only limited protection against manipulation due to the technology used, coded safety switches achieve up to 100% protection against manipulation. As a result, magnetic safety switches should be concealed or installed in such a way that they are invisible to operators.

If a safety switch cannot be concealed or if 100% protection is required, RFID coded safety switches are ideal. RFID technology enables a clear assignment between sensor and actuator. RFID coded safety switches operate in accordance with the ‘key lock principle’ whereby only one key – a unique version – fits a lock. Given that the actuator is installed using one-way screws – which can only be loosened via a special tool – a very high level of protection against manipulation is achieved.

It is also important to understand that magnetic safety switches have limited suitability if metal swarf is present, which can be attracted to the magnet and deposited on the switch, leading to operational problems or even failures. Although a safety-critical situation cannot arise as a result, plant availability and productivity will suffer. Here, coded switches are ideal, as RFID is unaffected by metal swarf.

Various coding types mean that different levels can be achieved in terms of security against manipulation. The greatest protection is provided by systems in which an actuator is uniquely assigned to a switch. Sensors with ‘normal’ coding are also available if the demands on manipulation protection are less stringent (one lock, many keys).

Gate closed in case of dangerRisks can remain even after a machine has been shut down, due to moving parts. In ‘hazardous overrun’ cases such as these, the use of a safe guard locking device is mandatory. This means that the gate cannot be re-opened until standstill has been safely detected or a time delay has elapsed. Here, mechanical guard locking devices with spring interlocks are typically used. The spring interlock guarantees that the gate can only be opened when it is safe to do so.

Integrated systems More can be achieved by using integrated safety gate systems that combine safe monitoring, safe guard locking and control elements, including additional functions such as E-STOP and escape release. All components – whether mechanical or electronic – are integrated.

Complete systems such as these help to reduce the time and costs associated with project configuration, design, documentation, purchasing and installation. Furthermore, if sensors and evaluation devices are sourced from a single supplier, this means that the interfaces between the various components are already compatible.

OEE

Historically, many manufacturing processes have tended to overlook ‘Quality’ as a ‘constant’, or simply a KPI for the QC department, rather than an opportunity for manufacturing process improvement. This mind-set has changed significantly in the past few years with the price of raw materials reaching an all-time high, a real drive towards RFT manufacturing, and increasingly demanding customer-driven audits.

Today, quality inspections range from automatic inspection on CNC machines through final inspection of every product, to checks on an agreed number of examples. (Some operations even rely on the customer making the quality checks but this is a risky and often expensive strategy!)

With so many shop-floor systems available, the question is whether quality checks and record keeping should be paper based, part of a large ERP system, or a stand-alone application? There are business cases for all of these options, but logically, building quality checks into OEE measurement makes perfect sense, as ‘Quality’ is a vital part of the calculation.

Quality is directly linked to the assets that make the product, and the number of products made, which are both essential elements in OEE. Moreover, the following information is already available in any comprehensive OEE System:

• Asset structure• Product definitions • Number of rejects• Reject reasons and locations.

We are also likely to have employee definitions of ‘rejects’, a touch screen interface, and two-way communications already in

place, so to measure and check quality using another system is simply duplication of effort.Some companies still use paper based inspection methods; perhaps an A3 sheet with the checks to perform down the left hand side with the rest of the page split into 15 segments. Quality Operators then perform the inspection tasks at 15-minute intervals, and enter a pass or fail value in each of the segments. Completed sheets are then filed, usually with some data entered into a spreadsheet for analysis, and only ever looked at again during a crisis related to batch traceability.

OEE – THE QUALITY MEASURE.My previous articles have focussed

primarily on how to improve the

‘Availability’ and ‘Performance’

elements that form part of the OEE

calculation (A x P x Q = OEE); today, we

examine ‘Quality’. It may be an urban

myth, but Henry Ford is supposed to

have said “Quality means doing it right

when no one is looking.” An interesting

thought, but can we really expect to

achieve perfect quality in a modern

operation without regular sample

checking? Probably not.

Automate this process, and not only does it take the pain (and

margin for error) out of data entry, but it also means that the data

collected can be used to inform the manufacturing Improvement

Agenda.

There are two basic requirements to automate the process: an

administrator to manage the check creation and an operator

console to capture the results.

Lets start with what we want to inspect. For a specific asset and

product combination, five elements need to be defined.

1: What is the measure?

It could be moisture content, weight, length, colour, temperature,

visual comparison, or calibration test.

2: What is the range for pass or fail?

If legislation dictates the weight must be 100 grams, the pass

options could be 100, 101, 102, 103, whilst 99 and 104 grams

are both fails.

3: What response do we expect?

It may be a value, text, yes or no, signature or pin number sign

off

4: What do we do when a fail is registered?

Send an automated alert, send an advisory message, or stop

the plant?

5: What is the frequency?

It could be by time, shift, product or ad hoc.

Of course, the ‘quality’ check does not have to be directly

related to assessing the quality of the product; it could, for

instance, require the operator to check and top-up an oil mist

bottle every shift. In this case we just need to know the task

clear to see the logic of including quality inspections in the OEE

management framework.)

Next we select a range of products or asset combinations, and

group the quality checks that are likely to be similar across the

plant; so the set-up process can be fairly quick. Once the quality

inspections are defined they can be scheduled to automatically

remind the Quality Operators when the checks are due. We can

then show when the checks are due, and react to any ‘missed’

inspections.

With a touch screen it’s quick and easy to enter the data, and

the results can be made visible across the plant: ‘ideal’ and ‘fail’

values can be clearly displayed so that the operator can just

touch the value of the measured sample.

Once the task creation and results are captured we need a few reports to measure adherence:• Did we meet the target frequencies?• Statistically how well are we doing?• Are we giving too much away?

With the values filed digitally, batch traceability is comprehensive. We have a record of the plant conditions when the results were captured, and we know which operator was logged on at the time. Because the quality element is recorded by the OEE System, we also know when production started and when it ended, how many products were made and the number of rejects. Crucially, we can also review every stoppage event or problem that occurred so we may be able to see which problem caused the quality issue in the first place.

The key advantage of building quality checks into the OEE System, is the ability to generate fully automatic alerts, so as soon as a critical fail is recorded we can send a text message and email to an individual or group, informing them that the values have fallen well below set parameters. This ensures that the quality issue can be rectified as soon as possible. It also means that there is no place to hide; the alerts can also be recorded so that we have a robust audit trail.

Of course quality measurement and recording can exist outside the OEE framework, but it makes sense to bring the two together as it results in time, resource, and financial savings. We

can use the existing hardware framework of touch screens for both activities, reducing our infrastructure outlay and improving return on investment. We can also remove much of the paper and provide instant reports, without duplicating the data analysis process. Much of the quality data is already captured in the system; the asset structure, product definitions, company calendars and employee definitions are already present. We can even use the existing employee security structure and pin codes for sign-off.

One final point, the operations team has access to stoppage and quality alerts in the same system. They can review production problems and successes and match them to quality results. Good production runs should deliver good quality statistics; the opposite may also be true. When urgent traceability is required; all the run parameters, people and products are accessible in a single place, which is especially useful during a customer audit.

John Ruskin famously said that ‘Quality is never an accident; it is always the result of intelligent effort’. The key word for me here is ‘intelligent’. Maintaining perfect quality doesn’t have to be arduous – with intelligent systems in place many factories could relieve the pressure on their manufacturing and operations teams, especially during audits.

Convinced? Ditch some of the endless paper trail, and try it; when the measurement systems are highly visible, and easily traceable, operations teams may agree with Ford that “Quality means doing it right when no one is looking.”

PRODUCT SPOTLIGHT – LEAK TESTING

WHAT IS PRESSURE DECAY?Probably the most common (and one of the oldest) forms of leak detection as, in terms of sensitivity, it is generally utilised to find liquid leaks.

There are two basic types of pressure decay measurement methods:

THE GAUGE METHOD

THE TEST CYCLE

CONVERTING TO FLOW UNITS

THE DIFFERENTIAL METHOD

This method employs a single sided measurement device (transducer). The technique employed is to connect the product to be tested to a regulated gas supply, with the sensing device (transducer) in circuit to indicate the pressure achieved.The pressure is then ‘locked’ into the system by use of a shut-off valve, and the transducer continually interrogated for a drop in pressure.The main drawback with this method, is the sensitivity, and because of this is more susceptible to temperature and other external effects.

With this technique, the component is pressurised in the same way however the difference is that both sides of the measurement transducer are also pressurised to the same level as the product. One side of the measurement transducer is then connected to the component and the other to a sealed reference. Very small changes in pressure then cause an imbalance (pressure difference) which can be directly measured.

Typical specification of such a transducer :

Sensitivity 0.1 Pa

Range 2000 Pa

Accuracy 1%

Repeatability 0.5%

Speed of response <100 ms

Most modern pressure decay systems utilise the differential method:

We need to carry out the following steps:• FILL the component to the required test pressure with

air.• TEST for leakage from the product (measure the

pressure decay).• EXHAUST the air from the component, (vent to

atmosphere) to allow safe removal.

However when a confined volume (the component under test) is pressurised there are a number of effects, such as temperature increases, which can cause false readings in the measuring cycle, so we must add a further stage:

• STABILISATION in between the fill and test phases to relieve the ‘adiabatic’ effects.

Pressure decay measurement can easily be related to flow by considering the universal gas law.

PV = constant (At constant Temperature)

From this basic gas law we can derive the formula:

Flow = Rate of change of Pressure x Volume tested

Atmospheric Pressure

From this we can derive:

cc/s = mB/s x VOL(cc)

1013

Many systems have this formula built into the software, so that the equipment can display the leakage directly in terms of Flow.
