OILING THE CHAINS OF INDUSTRY ‘The era of cheap energy is over’. Now there’s a revelation, I couldn’t see that one coming. Actually, lets get the picture straight. Oil, gas and coal are finite resources which will become ever more costly to extract. Renewables need a few decades, if not centuries, of development to become viable alternatives. Nuclear fell out of fashion in the UK. Our Government is more interested in tax revenue than discounting fuel. Finally, there’s global warming to lob in. Yes, I guess the era of cheap energy is over: for now. I believe market forces will drive the reinstatement of nuclear energy in the UK followed, in the end, by fusion reactors. Welcome to the new era of cheap energy. In the intervening 100 years or so we need a quick fix. One of the most important issues is factory design and maintenance. Be honest, in the past how much effort has been applied to calculating energy consumption before installing new plant or maintaining existing equipment. A leaking air line, jammed radiator valve, scaled boiler, slipping drive belt, corroded drive chain, old motor and controller, poorly lubricated bearing: the list goes on and on. Individually, the losses are small. Across UK industry as a whole I shudder to calculate the waste and consequences. With the cost of energy suddenly in the forefront of everybody’s minds, maybe it’s time to revisit maintenance processes.

Choosing the most cost effective maintenance procedure
Preventive maintenance
OPTIMIZATION Most Preventive Maintenance (PM) programs were set up many years ago. Each department in a plant set up their own program in isolation from each other. As an example, a plant set up a PM program covering mechanical equipment, then another program was set up for electrical equipment and another to cover automation and control system. A lubricant vendor then added lubrication routes and on top of this other PM activities such as Vibration Analysis and Operator Inspections was added in addition to all other PM tasks. It is not uncommon to also find that many old Fixed Time Maintenance (FTM) tasks, such as programmed overhauls and replacements, are still being done on an annual basis because that is what the plant always have done, and nobody has challenged the validity of these tasks. These tasks are often driven by the availability of time and maintenance people instead of the true validity of the task. In some industries, for example food processing, there might be a seasonal period when crops are not being harvested and processed. Maintenance people are then more available and some equipment are idling, so to keep people busy some equipment are overhauled and some components are replaced. The decisions to do these tasks are often based on believes rather than facts. This presents a good opportunity to ask if the life expectancy of components in question are predictable or known, and if there is a method available to do inspections while equipment is
Figure 1
Failures can be categorized as failure modes that develop over a period of time as visualized in the left graph. These failures have a Failure Developing Period (FDP). You can say there is a time difference between the point of failure until the break down occurs. A break down is when the intended function of a component ceases. A COMPLETELY REACTIVE MAINTENANCE ORGANIZATION will act upon break downs. A BETTER ORGANIZATION will find the failures before they develop into break downs. They will use the warning time they have gained by finding failures early to plan and then schedule a corrective action, and execute this action before the break down occurs. By doing so, you have started to optimize the life of a component. If you can estimate how long the FDP is you can use this information as a guide to decide the frequency of inspection. The frequency of inspection should be no less than FDP divided by two. BEST ORGANIZATIONS are spending considerable time to not only find failures and plan and schedule their corrections, but also to find the source of the failures and then design out those failures. Your organization has then evolved to a thinking and learning maintenance organization. If a failure develops over a very short period of time, which is typical for failure modes of electronic components, then there is no, or very short, time to discover a deteriorating condition. See the right graph. Condition monitoring is therefore not an option. In this case you can ask if the failure mode has a random or regular distribution in time. If the failure mode is random, and the FDP is very short, then it is a waste of time to do inspections of the component. You can inspect for example that the cabinet for electronic components is sealed and kept cool and clean and you should prepare a corrective action for when the failure will occur. If the failure mode has a regular, or predictable, distribution in time, then you can consider Fixed Time Maintenance, such as overhauls or replacements on a regular basis. I propose that you analyze all your FTM activities and question if they can not be moved to CBM and if their frequencies are right. My experience is that not more than 5 - 10% of all failure modes have a regular distribution in time.
Your Inefficient Motors are Wasting Money Are your motors overrated, are they running at their most efficient, perhaps their load is adversely affecting their operation? Unless you test your motors you will not know the answers. With Baker condition monitoring equipment, data from on and off-line motors can be quickly collected and analysed and action taken to improve efficiency and avoid critical failure. The Baker Explorer on-line tester offers a comprehensive view of motor health whilst the motor is running. It will also identify rotor bar, power quality, bearing and other mechanical issues.
The AWA Winding Analyser offers an automatic testing programme enabling less skilled staff to complete tests successfully, combining surge, polarization index, DC Hipot, megohm and winding resistance tests in one field-portable unit

operating. If the condition of a component can be measured while a production line is operating, then the condition of the component will determine what corrective action we can take to avoid a break down. If this is done we have chosen to do Condition Based Maintenance (CBM). As an alternative to the above mentioned PM activities you can also chose to Operate to Break Down (OTB). Best alternative is to Design Out Maintenance (DOM) or even better Design For Reliability and Maintainability before the equipment is manufactured. In this
article I am not going to cover these alternatives, I gave some examples of this in the March/April issue of this magazine. In 1968 I learnt about failure distribution in time and failure development periods, you might want to call this Reliability Centered Maintenance (RCM) methodology. In my opinion it is good common sense and it is the most useful part of RCM along with knowing the criticality of a component. To enable you to analyze existing PM tasks and optimize your total PM program you need to understand this concept.
Figure 2
Some of the readers might think that the aforementioned is just theory and not applicable in real life situations. To demonstrate the usefulness of understanding failure development theories when optimizing PM I like to show an example. The company has decided to replace the bearings once a year during the annual shut down. They had always done that but had still had three break downs of the bearings during the last ten years. The manufacturer’s handbook said “Once a year, open top of screen, idle screen and listen to the bearings with a stethoscope or similar device. If the bearings sound bad, replace bearings” To install transducers for vibration analysis of bearings is an obvious alternative. To do that will cost Euro 1500. The financial decision maker said no to the maintenance manager’s request to install the transducers because she thought it was too expensive and the maintenance manager had not provided a financial justification to install transducers. Besides that, she referred to the instructions in the manufacturer’s handbook and claimed that must be right. TO BE CONTINUED IN NEXT ISSUE. What is your opinion? How would you justify moving from FTM to CBM on the bearings of the screen? Please send your comments to info@idcon.com attn Christer Idhammar. I will send a reward to the best answers in return.

Christer Idhammar, president Idcon Inc The picture shows a rotating screen where incoming media is separated in good product, and reject. The inside rotary assembly rotates with 350 rpm inside a stainless steel basket with drilled holes. The diameter of stainless steel basket is one meter. The inside bearings are lubricated through two pipes. The rotary assembly is driven by an electric motor and V-belts. If the function of the screen ceases, it will shut down a process at a cost of Euro 20000 per hour in lost production. A break down of the bearings might cause the rotary assembly and the stainless steel basket to be destroyed at a cost of Euro 100000.

COMPACT UNITS, HIGH SAFETY With the new Septron Line series, the Christ Water Tech-nology Group makes it possible to produce ultrapure wa-ter in various qualities and quantities. The models 10-20 and 25-60 comply with the current standards laid down by ISO, CAP and ASTM. They also considerably exceed the requirements of the European Pharmacopoeia (Ph.Eur., Aqua Purificata) and the American Pharmaco-poeia (USP, Purified Water) for ultrapure water. All models can be commissioned quickly and offer a high level of operational safety with only low maintenance requirements. With the versions PRO, VAL and HPW, Christ offers a solution for every requirement. The PRO version is ideal for general industrial processes which need ultrapure wa-ter, while the VAL version meets the quality requirements of the pharmaceuticals industry and conforms with cGMP with respect to the FDA and PIC directives. The HPW is capable of producing Highly Purified Water (Ph.Eur.) which can be used in all ultrapurewater applications (such as rinsing water for microtechnology). The water, which has a very low conductivity, is also suitable feeding distillation systems (Water for Injections) and
steam gen-erators. All units are prequalified during the FAT (Factory Acceptance Test), which means that the time needed for onsite qualification and commissioning is greatly reduced. All units of the Septron Line 10-20 series have an operat-ing interface with three password-protected levels and with an electronic key. With a floor area of only 0.5m2, they can be installed in any laboratory. The units of the series 25-60 are the third generation. These have a PLC controller, comply with GAMP and CE and meet the re-quirements of the current standards for electrical and electromagnetic safety. Four password-protected control levels and an optional integrated printer for continuous tracking of all events and interventions ensure the maxi-mum possible safety. A clear menu system and a touchscreen display permit safe and ergonomical operation. With a floor area of about 1.2 m2, these units require little space. The entire Septron technology is characterised by optimal microbiological cleanliness. Christ achieves the re-quired water quality by means of the "smart-block con-nection technology", which has very few dead legs, and by using all treatment stages of filtration, reverse osmosis with full-fit concept, electro-deionisation and external ster-ile filtration (HPW quality). www.monitran.co.uk Reader Reply Number: 302
Airchannel wins new contract for Cosworth When Cosworth secured a contract to supply forged pistons to aero-engine manufacturer Lycoming, it turned to compressed air specialists Airchannel to provide the most energy efficient air package for their new piston line. Airchannel has historically supplied the Northants facility with 2 fixed speed Compair Cyclon 330 rotary compressors. However, because the new line required additional periodic capacity of up to 500 cfm, something the older compressors were not capable of, a new solution had to be found. Reader Reply Number: 330

J&P GROUP WIN £1M+ CONTRACT FROM AIRBUS
J&P Group have been awarded a £1m+ contract by Airbus to undertake a refit of one of Airbus’s key production lines at its wing manufacturing facility in Broughton, North Wales. The North Wales plant produces wings for all Airbus variants, including the new A380 super jumbo. The plant employs 6,500 people and is the region’s largest employer. Aircraft wings are manufactured from aluminium
billets that arrive in lengths of up to 31 metres and which can weigh up to 3.5 tonnes. Milling the billets into wing panels can take up to 50 hours using some of the largest computer-controlled milling machines in Europe. The contract will entail the removal and transfer of one of the 30 tonne skin milling machines to one of J&P Group’s dedicated engineering facilities where it will undergo an
extensive refurbishment. The machine has been in service at the Broughton plant for over 20 years and the contract therefore requires J&P Group to replace all obsolete components including the Machine Control, Axis Drives, Spindle and Toolchanger systems etc. On announcing the contract award, J&P Group Managing Director, John Begley commented: “J&P Group have been instrumental in developing and implementing maintenance strategies for a growing number of the Airbus milling machines in recent years. The award of this contract from Airbus is a testament to the dedication and skills of our workforce.” In addition to its core engineering services division, J&P Group also provide a range of expert services that include spares asset management, facilities management, supply chain management, procurement, warehousing & distribution and consultancy services. www.jandpgroup.com Reader Reply Number: 305

MONITRAN LAUNCHES ‘Monitran Technology’
Monitran has established Monitran Technology as its formal research and development arm. The new company will concentrate on the design of innovative products that exploit the use of new materials, technologies and techniques, particularly where joint ventures or knowledge transfer
partnerships are involved. Several such links are already being formed with leading industrial organisations and academic institutions. Donald Lyon, MD of Monitran Technology, comments: “Monitran is renowned as a leading OEM of vibration sensors for general and special purposes. Historically the product range has grown through the evolution of standard products, and this will continue. Monitran Technology has been set up, however, to handle the development and marketing of more innovative, cutting-edge products, for which specific research and partnering with other specialists may be required.� Whilst not revealed at the time [March 2008], the most notable initial development project for Monitran Technology has been the partnership with QinetiQ to develop the T3 Turbomachinery Tip Timer.
Lyon continues: “Monitran Technology is our future-facing R & D arm, backed up by Monitran’s strong heritage of over 21 years of manufacturing experience. The aim is to identify and realise market-led opportunities for the development of innovative solutions for challenging applications.� Other recent developments from Monitran’s research arm include sensors able to cope with high shock-loading on wind turbines, wireless systems for wind turbines, integrated compensatory electronics to cope with bias-drift and linearity, and an acoustic emission sensor to detect defects in compressor valves. Lyon concludes: “Our formation of Monitran Technology is both a positive response to market requirements as well as a testament to our firm belief in the design ingenuity and capability of British industry.� www.monitran.co.uk Reader Reply Number: 307

CONDITION MONITORING
REMOTE CONDITION MONITORING
OF WIND FARMS As the use of wind turbines continues to spread across the globe, systems that are able to remotely monitor the condition of the rotating equipment is becoming increasingly important, helping to give wind farms advance warning of any impending turbine component failures While the erection of new wind turbines in countries where wind power has already been used for several years has reached market saturation, there is still strong growth in younger developing countries. For companies that operate on a global level, for example, the benefits of using permanent remote monitoring services provided by a qualified monitoring centre can be a very attractive option. In Australia, wind power as a source of renewable energy has to compete with
the relatively cheaper energy produced by Australian coal power plants. Only the selling of “Mandatory Renewable Energy Target (MRET)“ certificates with which the Australian Government encourages the use of renewable energy sources has made wind power an interesting and viable option for these companies. Although the current version of the MRET scheme may not go far enough in encouraging the use of wind power, individual states have already adopted
extended schemes designed to encourage renewable energy generation. FAG Industrial Services (F’IS) is the maintenance and condition monitoring company within the Schaeffler Group. In early 2006, a total of 49 ‘FAG WiPro’ (Wind Turbine Protection) systems were installed for a customer in two major projects in Australia. Codrington Wind Farm is located on the South coast of the state of Victoria and was originally constructed in June 2001.
13 EMS May/June 2008 www.engineeringmaintenance.info
CONDITION MONITORING
The wind farm comprises 14 turbines, each with a capacity of 1.3MW. Challicum Hills Wind farm has 35 turbines with a capacity of 1.5MW each and was originally commissioned in 2003. The turbines are located on a range of hills near the city of Ararat in Western Victoria. The condition monitoring systems installed there are serviced by Condition Monitoring Services Australia (CMSA) – a subsidiary of F’IS – which employs around 25 staff and has offices in all regions of Australia and New Zealand. As all F’IS monitoring centres are in permanent contact with each other, there is a constant exchange of condition monitoring information and experience. However, choosing the most suitable communication channel is often a genuine challenge – and not only where large-scale projects are concerned. This includes not only the transmission of data within the wind farm but also transmission to a service station, which is indispensable for remote monitoring. The majority of wind farms have a telephone line to the outside world, but it is used primarily to monitor electricity production data. This telephone line also determines the maximum possible transmission rate for the farm, so installing high speed networks would not be much of an advantage in the network within the wind farm. When selecting the most suitable communication channels within the site, a number of factors must be taken into account, including the size of the wind farm, the distances between the individual turbines, existing optical wave guides or copper lines – possibly in the form of a network – as well as the cost of data transmission. For wireless transmission (for example via WLAN), the geographical conditions must also be taken into account. At both Codrington and Challicum Hills wind farms, no lines between the turbines could be used, so only the wireless transmission option remained. In Challicum, the site uses GSM technology (fully digital wireless network), as the customer was able to reduce the cost of GSM transmission drastically, thanks to a special agreement with its telephone company. In contrast, at Codrington Wind Farm, the GSM network coverage was not sufficient for reliable monitoring, so the site uses CDMA modems instead. The advantages offered by the CDMA technology (multiplex system) include the
possibility to establish networks and then access these networks via the Internet. This offers significant advantages over a standard GSM version when it comes to data security and cost. After the most suitable communication channels had been selected and the systems installed, the measuring tasks for the FAG WiPro condition monitoring systems were then defined. The favourably priced FAG WiPro system, which is available with up to 8 sensor channels and the ability to perform 16 measuring tasks with 12 frequency windows each, is a powerful vibration monitoring system for permanent, frequency-selective monitoring. Monitoring the condition of large wind turbines (3 to 5MW) of the type erected preferably in offshore regions, the size of the components may make it necessary to use additional sensor technology and to perform additional measuring tasks. As the monitoring activities in offshore turbines may extend to include additional machine components, users should consider the recently-developed FAG ProCheck online condition monitoring system. Jointly developed with National Instruments, this innovative online condition monitoring system can accommodate up to 16 sensor channels plus additional analogue and digital inputs
14 EMS May/June 2008 www.engineeringmaintenance.info
and outputs, and so can be expanded from monitoring an individual machine, right up to monitoring complete production plant systems or wind farms. Multiple FAG ProCheck units can be connected to a network and managed using the same database. To summarise, such large-scale wind turbine projects on a global level can only be realised with an efficient team of specialists on site. Both the installation of a major project and service in close contact with customers cannot be ensured without the presence of condition monitoring specialists in that particular country. Although logistics in the wind turbine sector are typically very complex and costly, being able to plan maintenance activities efficiently is so important in view of the topographical conditions prevailing in Australia. F’IS online condition monitoring systems such as FAG WiPro and FAG ProCheck ensure the user receives a lengthy advance warning period. In this way, technicians, material (delivery periods) and sometimes even a heavyduty crane, can be dispatched in plenty of time so that any unexpected shutdowns can be prevented. www.schaeffler.co.uk Reader Reply Number: 308

ENVIRONMENTAL MANAGEMENT
Spiralling energy costs have put energy efficiency on the top of everybody’s “to do” list and has raised the question about the sustainability of traditional air conditioning systems
COOLING WITH environmental responsibility EcoCooling Evaporative cooling systems provide a simple, safe, and low cost alternative to cooling buildings at a fraction of the cost of air conditioning systems. Evaporative cooling costs 90% less to run than a traditional air conditioning. It works as part of a balanced ventilation system providing cool fresh air through a carefully designed ventilation system which directs the cooled air through the building to the areas where it is needed most whilst expelling the hot air through open doors or extract fans. This simple form of cooling can provide 35kw of cooling from just 1kw of electricity and provide cooled air always below 24C in the UK. One cooler can cool an area of up to 200sqm or spot cool work stations or machinery. EcoCoolers have been used successfully in all types of industries from bakeries and warehouses to print works and offices. The inherently simple
technology is complemented by a sophisticated control process which provides complete piece of mind when it comes to hygiene. In addition all EcoCooling installations can be connected to main BMS systems. At 25% of the installation cost and just 10% of the running costs of air con, small to medium sized enterprises can also qualify for a 4 year interest free loan from the Carbon Trust because of the carbon savings incurred by using evaporative cooling instead of air conditioning. These loans are often large enough to cover the complete installation cost of the coolers. EcoCooling products are supported by specialist contractors who can produce complete turnkey projects including design installation and maintenance. One company that has recently benefited from this expertise is Stylo shoes where 15 EcoCoolers were used to cool the main picking area on
the top floor of their 3 floor distribution warehouse in Bradford. Due to a large number of skylights and a single skin roof, the working conditions were oppressive during the summer. Stylo wanted an energy efficient and effective solution to cool the area down. Having previously explored the options of air conditioning which had been dismissed out of hand purely on installation costs, Nigel Booth (Group Property Manager) asked EcoCooling to produce a proposal that would both cool the environment down and increase air quality. After discussions through consultants and contractors and a complete assessment of running costs and annual servicing cost, 15 down discharge EcoCoolers and six extract fans were installed in May 07. A basic control system ensures that the air input and extract systems work together and simple time clocks ensure that the system shut down at the end of each day.
The air is distributed down the main picking aisles and over the unpacking and dispatch zones. Site facilities manager Keith Pemberton confirmed that conditions in the warehouse during summer 2007 had been “beautiful” and there were noticeable decreases in absenteeism and a better working atmosphere both literally and metaphorically since the completion of the installation. www.ecocooling.org Reader Reply Number: 309

What is the economic added value of
maintenance? "What is actually the added value of maintenance?" is a frequently heard question in boardrooms the world over. Even though maintenance is often critically important, few maintenance managers are able to answer the question convincingly. Especially when they are asked to express the benefits in terms of economic value added or shareholder value - the language increasingly being spoken in European boardrooms Not being able to answer this important question often leads to the conclusion that maintenance is nothing more but a cost center. And the thing about cost centers is that they can only generate economical value by improving efficiency, causing the maintenance department to become a willing victim of one cost cutting program after another, and with consequences for the availability, reliability and safety of the factory, aero plane, ship or infrastructure that has to be maintained. Many maintenance experts therefore claim that steering
on economical value added is a serious threat to maintenance. It only causes cost reductions and is short term focused. I donâ&#x20AC;&#x2122;t agree with this criticism. Even stronger than that; if you interpret the concept of economical value added correctly, it offers enormous opportunities for maintenance. To be able to understand this, we first have to understand the concept of economical value added. In the financial literature economical value added is defined as: â&#x20AC;&#x153;the sum of all free future cash flows,
discounted to todayâ&#x20AC;?. A free cash flow is the difference between income and expenditure. So a company is creating value when it is earning more money than it is spending. Also, value focuses on the future. Achievements from the past are not taken into account when valuating the company. It is about future expectations. We do have to mention that these future expectations have to be discounted to today, to more or less level these cash flows and make them more realistic. If we apply this formula to maintenance, we will see that
maintenance can create value in more ways than by lowering maintenance costs (Cost Control) alone. In a market where there is more demand than supply, greater machine availability (Asset Utilization) means more income and thus a higher value. Similarly, the safety, health & environment (SHE) factor affects value. SHE accidents tend to necessitate substantial expenditure, which result in large negative cash flows. Think of expenditures due to damage to personnel, the environment and image. An even greater danger is the loss of the license to operate,

because of an inability to comply with SHE legislation. No license to operate means no production and therefore no income at all. Finally, maintenance can also create value through the smarter management of recourses (Resource Allocation). Especially the stock of technical spare parts has a negative impact on value because there aren’t any returns on invested capital. Maintenance managers steering on economical value added are continuously looking for the optimal economic balance between these for conflicting value drivers. Calculation models and benchmark studies can help to clarify the improvement potential on each value driver. Note that this value potential will differ markedly depending on the industry involved. In
the bulk chemical industry, for example, the prices worldwide are under considerable pressure although the technical availability of these plants most of the time have already been brought up to high levels. The value potential here lies mainly in Cost Control and the smarter deployment of people and recourses. In the pharmaceutical industry, the situation is the other way around. With a lot of patented medicines demand is greater than supply, but the technical availability of the production process is relatively low. This matter is obviously receiving attention. The SHE factor here is becoming more and more important with the growing role of the American regulating FDA (Food & Drug Administration) in the European pharmaceutical industry.
Practice shows that thinking in economical value added will help the maintenance manager to professionalize maintenance. It helps the manager to better sell maintenance within the company. With value driver calculations it can be demonstrated to the upper management that in many cases investing in maintenance will create more value than cutting costs. With economical value calculations it can also be demonstrated that intended maintenance improvements will definitely contribute to the well-being of the company, despite the facts that the results won’t be visible until a few years ahead in time. So it isn’t only short term politics or cost focused; it seamlessly connects to the true importance of maintenance.

OEE
As today’s businesses focus on the triple bottom line of finance, social responsibility and the environment, the challenge for lean manufacturing increases. While OEE Systems are known to identify inefficiency in machine availability, production speed and quality, the subsequent reduction in energy consumption is a lesser known fact
HOW HOVIS SAVED
THOUSANDS ON ENERGY OEE provides a way to measure the effectiveness of manufacturing operations from a single piece of equipment to an entire manufacturing plant, or several manufacturing plants in a group. In doing so OEE provides a complete picture of where productive manufacturing time and money is being lost and uncovers the true, hidden capability of the factory. It becomes the key manufacturing decision support tool for continuous improvement programmes. OEE measurement is made up of three underlying elements, each one expressed as a percentage and accounting for a different kind of waste in the manufacturing process: Availability: a measure of the time the plant was actually available for production compared to the manufacturing requirements. Any losses in this area would be due to major breakdowns or extended set up time. Performance: the rate that actual units are produced compared to the designed output. Losses in this area would be due to slow speed running,
minor stoppages or adjustments. Quality: a measure of good quality, saleable product, minus any waste. Loses for this element would be damaged rejects or products needing re-work. OEE = Availability x Performance x Quality. Today’s OEE Systems provide a powerful tool for automatically capturing and measuring OEE performance data, enabling analysis and drill-down to drive the continuous improvement agenda. The truth of the matter is that it is very difficult to manage or improve what you don’t measure. The improvement potential that OEE highlights can surprise even the most experienced production professional, especially the potential to improve energy efficiency. Most manufacturers have already implemented a wide-range of energy related programmes with varying degrees of success including: switch-off campaigns; intelligent production scheduling at a lower time-tariff; installing new energyefficient equipment or enhancing maintenance to reduce leaks. All of these programmes are necessary for an ongoing improvement in energy consumption but they are not sufficient on their own. There is a bigger prize to be gained in operating
the factory as effectively as possible to maximise energy-efficiency. OEE Systems enable companies to discover ways to enhance their energy efficiency way beyond conventional energy saving programmes with dramatic results on their carbon footprint. And there is proof to support this claim. Hovis, the bread producing division of Premier Foods (the UK’s largest food producer), is very familiar with high volume, high-pressure manufacturing process. Producing the nation’s daily bread to the tune of 2 million loaves a day requires precision operation, efficient production and a skilled, professional workforce. One of the UK’s largest plant bread bakers, Hovis has over 6,500 employees and supplies around one third of the UK’s daily bread. By harnessing the power of the Idhammar OEE System to gain greater production efficiency, Hovis was able to reduce its annual gas budget, saving £400,000 in 2007 alone. “In addition to savings in labour unit cost and product wastage, we have achieved significant savings in energy usage. Optimised OEE has a hugely beneficial impact on our energy-efficiency programme which supports our environmental objectives” said Bob King, formerly the Manufacturing

OEE
Director for Hovis and now Group Head of Operational Excellence for Premier Foods. A number of production related factors contribute to wasted energy; 1. Breakdown – apart from the broken equipment, during breakdowns most of the plant (conveyors, pumps, ovens, shrink tunnels, etc.) continues to cycle, wasting large amounts of energy. 2. Start-up – most items of plant use more energy, particularly electricity, at start-up than at normal operating speed, , so if the plant breaks down frequently more energy is used. 3. Slow running equipment –the same amount of energy used to operate slow running equipment is required to run equipment functioning at full capacity 4. Rejects – substandard products waste all the added-value used to manufacture them including labour, materials and energy 5. Under-utilised capacity – companies regularly invest in additional capacity which increases carbon footprints, unaware that existing lines are underperforming and could provide the production increase they are looking for. It is well proven that improvements to existing plant are 10 times more effective than the installation of new capacity and result in reducing energy requirements. The following diagram illustrates the impact of a particularly bad day on the shop floor. Every day unplanned production stops, slow running equipment, lack of materials and wrong date codes cause waste, not only impacting productivity, but also impacting energy efficiency.

of manufacturing production, OEE calculates the average performance of productivity (throughput), availability (uptime) and quality (wastage). The Idhammar OEE System takes all of these and adds an energy module, providing automatic measurement, monitoring and clear reporting tools to enable forward-thinking manufacturers like Hovis, to identify areas of waste and evaluate the actions taken to improve both production and efficiency. By using OEE to drive improvements across fifteen bakery sites, Hovis were able to benefit from huge savings to gas consumption. Far from increasing energy spend as expected in line with energy inflation, Hovis made a 7% annual reduction to the bottom line as illustrated in the chart below. While this example concentrates on energy consumption, the same results may be achieved when monitoring and measuring water usage – resulting in further savings.
Greater general awareness of environmental issues together with rising energy costs and increased Government targets has caused manufacturing energy consumption to rise to a board-room level concern. It is no longer acceptable for companies to treat energy simply as a fixed cost of production, there is an urgent requirement to monitor and improve energy-efficiency. OEE systems provide the rich functionality necessary to expose exactly what percentage of production time is truly productive and to dig deeper to reveal the causes of lost productivity and waste. Increasing your OEE score not only means enhanced production capacity, but greater energy efficiency too, resulting in visible benefits to the bottom-line. www.idhammarsystems.com Reader Reply Number: 311 ABOUT THE AUTHOR Clare Darlison is the Technical Director of Idhammar Systems.
Manufacturing – Gas KW per hour / Tonne (saleable) – YTD 06/07 cumulative view
OEE Talking to Joel Leonard, the ‘maintenance evangelist,’ during an evening session at EuroMaintenance in Brussels, a candid question was asked ‘what is more important – managing maintenance or overall equipment effectiveness (OEE)?’
Maintenance and OEE – how close is the link? We spent some time discussing the importance of each element, but could not prioritise either way - the concepts are directly linked, despite the curious fact that often the maintenance and production functions in a plant work in isolation Computerised Maintenance Management Systems (CMMS) have, for many years, been regarded as an essential element in the engineers’ toolbox. Indeed, maintenance engineers the world over use CMMS to manage mission critical activity. But unfortunately these systems are often used by Operation and Production departments as the means to report the extent of ‘engineering failure’, with ‘engineering breakdown’ records used to excuse missed production targets. This limited view usually results in ‘engineering’ being blamed for most output failures, but worse, it results in a great deal of lost economic opportunity because no one is keeping score of the other performance issues which effect Overall Equipment Effectiveness (OEE). At the other extreme, OEE Systems are regarded as a production tool, often ignored by engineering and as a result,
restricting the value of some engineering KPI’s. Whilst engineers may work hard to complete maintenance against plan, can we be really sure the plan is sound and is the most effective way to eliminate losses and improve plant performance? There is little point in praising the engineering department for completing 490 out of 500 work orders on time unless we can be sure those 500 tasks were necessary and effective. The key issue for maintenance engineers must be to identify and complete the most appropriate maintenance. To quote Peter Drucker, management guru: “Efficiency is doing things right; effectiveness is doing the right things.” Knowing exactly how well the plant is performing will help to drive engineering to do ‘the right things’. It seems obvious then that we must direct maintenance to critical areas identified by OEE and loss management. So why not bring the maintenance and production functions more closely together? Why not use the data from OEE analysis to generate maintenance requirements? An effective OEE System will also measure
failures, reporting on when, how, and for how long, as well as providing MTBF and MTTR. Companies who recognise the value of OEE usually begin with a spreadsheet for each production line; however a spreadsheet simply doesn’t have the power most complex plants needs for OEE analysis, and cannot normally provide the maintenance pointers engineers need. Companies very quickly ‘outgrow’ this spreadsheet approach. OEE management should also consist of more than a series of graphs in production department corridors. A
dedicated OEE System, including software, business processes and a supportive shop-floor culture, should provide direction for the maintenance strategy and the key tool for loss management. Let’s consider the glue unit as an example: Using an OEE System to analyse the unit, drilling down through OEE availability metrics reveals that glue issues are resulting in the worst loss - over 700 minutes in a single week. An immediate temptation is perhaps to have the engineers strip the unit during a quiet evening period, clean, replace
The metric shows that the glue unit availability is running at a loss of over 700 minutes in a single week. Drill down analysis highlights supply as the root cause of the issue.

some worn parts and hope for a better run tomorrow. However, further analysis shows that the result of not having cartons or outers, has lost a total of 500 minutes. Perhaps the FLT driver is just not getting the right items in the right place at the right time; surely this is an easier problem to resolve than an unspecified, potentially complex engineering issue. Furthermore, ‘what if’ OEE analysis shows that several machines of a similar type are having the same problems, a ‘5 why’s’ test is completed and the results show that the root cause of lost time for the week is glue supply. Appropriate counter-measures such as auditing the glue supplier, checking incoming batches etc. will prove more effective. Stripping the glue unit could well have made the matter worse. Completing the
26
wrong/unnecessary maintenance, even if done quickly and to the highest standard, won’t enable the plant to run to speed. Maintenance decisions, then, need to be made using accurate and complete performance data. But often companies spend too much time gathering data, leaving little time to re-act to that data. OEE tools need a powerful improvement agenda so that as incidents are identified, targets, reviews and completion dates can be set. These tasks should be highly visible, provide clear accountability and clarify improvement responsibilities. At all times, every department should be able to answer three questions: When was the last time a 1 hour breakdown occurred? When was the time before that?
What about the time before that? And then three more: What maintenance counter-measures have been put in place to eliminate the issue? Is the maintenance plan working? Does the whole team understand what was lost, and the financial prize to be gained? And the answers should be the same. Constantly measuring OEE and aligning maintenance plans according to the results will ensure that the most effective maintenance is planned and the most accurate picture of performance is painted. One final point; if you believe your CMMS alone can improve your plant’s performance, I’m afraid you are missing the bigger picture. On the other hand, don’t underestimate the fact that good

CONDITION MONITORING
Maintenance personnel are justifiably wary of new technological developments. What looks good on paper may not be so useful or practical on the shop floor. Take instrumentation with wireless communications for example, just how easy is it to use and how reliable is it in practice?
NEW OPPORTUNITIES WITH
wireless condition monitoring sensors Our experience is that in its present state of development it’s a very useful option although not necessarily the answer in all cases. However one thing is for certain, wireless technology isn’t a ‘one month wonder’. A common approach to implementing wireless Condition Monitoring (CM) technology is to have a hub with wireless communications into which a number of conventional CM sensors and instrumentation can be hardwired. This has the benefit of removing the communications cable between the hub and the remote data handling system but has the disadvantage of still requiring hardwiring from each of the sensors back to the instrumentation and into the wireless hub. An alternative approach is to have the necessary signal processing and wireless communications built into the CM sensor itself. The advantages of a wireless CM sensor are : Easier retro-fitting to established machinery. Easier installation on awkward, moving & restricted access machinery.
Greater flexibility to re-site sensors as monitoring concerns change. Dramatic reduction of data being transmitted (and ultimately handled by the remote data handling system). Although wireless sensors require a greater degree of integration and a bigger investment, the advantages are such that it may well be the approach of choice in the long run. For these reasons we have been developing such a wireless CM sensor at Holroyd Instruments but before launching into a description, it is first necessary to briefly explain its measurement capability. The sensor is based around the high frequency technology of Acoustic Emission (AE), which is one of the four CM technologies specified in the ISO 18436 Condition Monitoring standard. Whilst all four technologies have their role to play in a comprehensive CM strategy, AE technology brings specific benefits to such a CM sensor when compared with, say, vibration technology : Ability to easily monitor very slowly rotating machinery. Good tolerance to line speed variations.
Figure 1 Schematic diagram of the MHC-ViTAE® wireless CM sensor
Figure 2 Photo of the MHC-ViTAE® wireless CM sensor
Removal of need to tune or set up for different speeds, bearing details etc.. Applicability to plain as well as rolling element bearings. Identical alarm levels over a wide range of machine types and conditions. High sensitivity to developing faults without recourse to frequency analysis. Importantly the above benefits have been proven over many years on the industrial shop-floor on tens if not hundreds of thousands of machines using portable CM instruments. With AE technology it is therefore realistic (i.e. useful and practical on the shop floor) to integrate the signal processing, and even alarm levels, into the sensor itself. Accordingly the sensor we have created has an architecture shown schematically in Figure 1 and takes the physical form shown in the photo in Figure 2. Without going into unnecessary detail this sensor (called the MHC-ViTAE®) has industrial strength Bluetooth Class I communications as well as an internal antenna and rechargeable battery. In terms of its functionality it allows wireless access to its : alarm functions (including initiation of email messaging).

deep trend history of preprocessed fault sensitive parameters. diagnostic waveform outputs (e.g. remotely listen to activity on a remote PC as a .wav file). So in terms of functionality the MHC-ViTAE sensor is no slouch but where will it be applied ? The most obvious area is for retrofitting onto machinery that would otherwise be very awkward to hardwire. For example, initial areas in which we are working with clients are on overhead cranes, wind turbines and monitoring specialised machinery that necessitates the sensor being mounted on rotating parts. The other lead area of application is where the cost of hard-wiring a multi-channel CM system would be prohibitive. Another area of concern with wireless communications is range. With hard-wired systems you can be confident that signals will get through, provided specified maximum cable lengths are not exceeded. However with wireless sensors few organisations currently have the necessary experience to have such confidence. In fact it has been a learning curve for us over the last few years as we have developed the MHCViTAE sensor. Although off the shelf BluetoothTM Class I modules (as used in our sensor) are specified to have a range of 250 metres in standard form (1 km in the longer range form) we refrain from making any bold claims for our sensor. We have shown that within a factory environment it is entirely realistic to expect the standard form to establish a reliable communication link over a distance of around 50 metres even when machinery obstructs the direct path between the sensor and PC. Furthermore, we have yet to find difficulties when the PC is in a control room or the machine being monitored is in an acoustic enclosure. In fact

the typical response of maintenance personnel when first seeing the sensor in action on their shop floor has been one of astonishment at the ease of connection and range of the sensor. To provide an example Figure 3 shows a bar graph of the readings of the four standard pre-processed parameters used for slowly rotating machinery taken on the top of two gearboxes on an overhead crane. No problems were experienced in establishing a connection to a PC at ground level at a distance of 40 metres. Note the dramatic difference in the readings taken on the two gearboxes clearly indicating a mechanical concern (and in this case able to be confirmed by climbing up to the crane and directly listening to the two gearboxes). However one other issue of practical concern is the supply of electrical power to a wireless sensor. The built in rechargeable battery of our sensor has limited power so for long term monitoring or regular wireless communication it will be necessary to provide an external DC source. This could be from a larger battery (or even energy harvesting) but our experience is that it is usually most convenient to simply utilise local electrical power. So having looked at practicality issues such as applicability, ease of use and connection reliability the final concern of an end user is that
of price. When you consider that a standard AE sensor contains only the piezo crystal and the pre-amplifier (the circle and the triangle in Figure 1) it is clear that there is much more technology packed into the wireless CM sensor that has been described. In addition the creation of the sensor has required the development of much microprocessor code as well as the PC software which provides the user interface. This inevitably results in a higher selling price than that of a standard AE sensor, which it must be remembered also needs a separate CM instrument. However it is realistic to think in terms of a wireless CM sensor having a similar price to the combined price of a conventional hardwired AE sensor and instrument. In other words, the savings on sensor cabling and installation costs that a wireless CM sensor offers can be 100% savings to the end user. So there it is, wireless CM sensing offers easier and lower cost installation and because it is wireless it has one final advantage over hard-wired system - you can move the sensor at any time to continuously monitor a machine that is giving you increased concern. Thatâ&#x20AC;&#x2122;s got to be worth looking into. Article written by Trevor Holroyd

COMPRESSED AIR
Already recognised for its innovative dual output compressed air/nitrogen technology, Atlas Copco now offers its new NG series of advanced nitrogen generators to provide a continuous, reliable secure and independent source of on-site nitrogen generation at the lowest possible cost for a broad spectrum of industry applications
Atlas Copcoâ&#x20AC;&#x2122;s NG generators provide on-site pure nitrogen supply 24/7 without the need for cylinders Whether in chemical manufacturing, electronics, laser cutting or food processing and packaging, a dependable supply of nitrogen is crucial to the many production industries which regard nitrogen as the fourth utility after gas, electricity and water. Based on Pressure Swing Adsorption (PSA) technology, Atlas Copcoâ&#x20AC;&#x2122;s NG series provides a continuous flow of nitrogen of desired purity from 97% to 99.999% at flow from rates from1.3 up to 130 Nm3/h. The modular design of the eight model range means that specific NG nitrogen generators can be used in parallel for the
most cost-efficient solution. If extra capacity is required at a certain point, modules can easily be added. The cost-effective choice Focusing on the purchase price of nitrogen, many companies still rely on gas cylinders or liquid nitrogen as their source. But, rather than a one-time acquisition cost, these sources constitute an on-going array of expenses. When the costs associated with order processing, cylinder rental and handling, delivery and safety are considered, these hidden expenses can
contribute to escalating overall cost and lower profit margins. In contrast, the installation of Atlas Copcoâ&#x20AC;&#x2122;s NG nitrogen generators eliminates these extra costs and provides a reliable and safe nitrogen supply. Reader Reply Number: 313

AREA Dock Loading Pods can be used in a number of different ways but most commonly in temperature controlled buildings or where internal floor space is at a premium. The benefits are that the construction can be produced to suit an ambient building just as easily as a temperature controlled store – the concept is the same. The Dock Loading Pod itself is a robust steel frame that can be clad with a variety of materials, for example with a Kingspan composite panel, and is mounted on a steel base already prepared for one

of sara’s market leading dock levellers. On the back of the Dock Loading Pod the thermal barrier is usually a sectional overhead door, electrically operated and sequenced with the dock leveller and traffic light system to produce a tailored, systemised loading bay solution. The sealing between the vehicle and the Dock Loading Pod can be achieved in a number of ways depending on the thermal efficiency required but dock shelters, foam dock pads and inflatable dock shelters are all available and can be fitted to pods.
Because the units are modular but tailored, delivery and installation is quick and without fuss and carried out using sara’s own engineers: another way of conserving energy.

HEALTH & SAFETY
Balcan throw a lifeline The Balcan Emergency Life Line – BELL – should be set to take on a much higher priority and significance with directors and managers of organisations and companies responsible for ensuring the public and employees have the most effective lifesaving equipment on hand following the Manslaughter and Corporate Homicide Act, which became law this April, believes its inventor John Rinfret, managing director Balcan Engineering Limited. The new law applies to almost all corporate bodies - large and small, private and public, which include those who bear the responsibility of ensuring that there is appropriate lifesaving equipment on hand, which could prevent fatal accidents. Under the Manslaughter and Corporate Homicide Act, an offence will be committed where failings by an organisation's senior management are a substantial element in any gross breach of the duty of care owed to the organisation's employees or members of the public, which results in death. This is particularly relevant to organisations such as Fire & Recue and the Police. Failure to comply with these requirements can have serious consequences for both organisations and individuals. Sanctions include fines, imprisonment and disqualification. The maximum penalty is an unlimited fine and the court can additionally make a publicity order requiring the organisation to publish details of its conviction and fine. The Balcan Emergency Life Line – BELL - invented in 1973 and launched at the 1974 London Boat Show, has the remarkable ability to allow anyone to throw it without prior preparation and
without tangling up to its full length of 40 metres and was immediately recognised as potentially a vast improvement on all existing lifesaving and rescue equipment because of its exceptionally long reach. This was because it could be thrown both over and under arm in excess of 30 metres further than the traditional lifebuoy, which at the time was the only lifesaving equipment in common, usage. Not only can it achieve rescues at distances which would have been impossible previously, but the device is so compact there is no excuse for it not to be carried or located whenever and wherever it might be needed. It will be this fact that may very well cause liability issues when drownings occur posing the question as to what reason was there for the BELL not to have been available? Whilst Balcan has occasionally received criticism that the fine braided line may scuff the hands of both the victim and rescuer and that the empty capsule may even cause injury should it actually hit the victim, it is considered this is not a sufficient excuse and defence for not providing the BELL as the obvious alternative is to provide a shorter thicker line with a much less reach which could have contributed to the resultant drowning tragedy. This problem was foreseen and highlighted as the result of a typical drowning tragedy which occurred in the early 1980’s on a frozen reservoir belonging to the North West Water Authority in Lancashire. Two boys had formed a slide on the ice which when it broke threw one of them into the icy water. The other ran to the office of the reservoir manager who was unable to achieve a rescue with the available lifebuoys because of their limited range. At the inquest the Coroner severely criticised the NWWA for providing such limited safety equipment. This resulted in Balcan receiving an urgent order for 400 of their BELLs. In the light of the Coroner’s criticism Balcan sought Counsel’s Opinion about an employers liability should a drowning occur out of reach of the lifesaving equipment provided. The Opinion stated that if the circumstances of the drowning could have been foreseen to indicate that the equipment provided was inappropriate and if other more appropriate lifesaving devices were readily available on the
market with say a longer reach then a liability could be established. Whilst reports of official approvals and remarkable rescues subsequently built up it was not until 2000, just 27 years since BELLs were first launched, that they received official international recognition of their superiority! In December 1999 Balcan was approached by the naval support of the MOD who needed to trial BELLs for use by the Royal Navy who had recently lost their Crown Immunity and were now required to bring their lifesaving equipment up to the current standards of the Health & Safety at Work Act. By March they were advised that BELLs had been assessed as superior to all other equipment because of being easier to throw with greater accuracy much further than anything else and as a result all 3 models of BELLs would be allocated NATO Stock Numbers (NSNs) by the Royal Navy so they could be used by all members of the Armed Forces. In fact we understand they remain the only line to have received this accolade. After the introduction of the BELL other throwing lines came onto the market in the form of plastic duffle bags filled with much shorter and thicker lines claiming to be easier for victims to see and grab. These claims were clearly incorrect because being only 15-20 metres in length the lines could quite obviously drop some distance short of the victim that the BELL could otherwise have reached so would not be so easy to see nor grab! The BELL comprises of a specially designed bright orange plastic capsule into which a specially wound cop of buoyant polypropylene braided line of 118kgs breaking strength is fitted. This is 5 kg stronger and 10 metres longer than that specified in use for life-rafts and lifeboats. One end is tied to a stainless steel washer to ensure it is retained within the capsule and the other passes through the handle and formed into a loop to act as a grip. In use the blue sealing cap over the mouth of the capsule is pulled off and the line is gripped in one hand whilst the capsule is thrown over and past the victim who is then able to grip the line somewhere along its length and is then hauled in to safety. www.balcan.co.uk Reader Reply Number: 318
