Not quite a Baker’s dozen IT has been almost 13 years since I took on the role of editor of DEMM. Since 1998 the magazine has undergone a lot of changes, many of them subtle and some quite significant. Of course, in that time the Internet has become a powerful force in our lives. Today it is the major conduit for reader enquiries generated by the magazine. DEMM Engineering & Manufacturing magazine, which is celebrating its 43rd year of publication in 2011, has much to be proud of. Over the years it has played a central role in linking buyers with sellers – it has been an industrial marketplace that has generated a lot of business for countless companies. Nowit has matured into a truly informative and educational publication, still with a strong focus on all engineering and manufacturing disciplines, not least of which is maintenance – arguably the most important discipline of all. The time has come to open a newchapter for the magazine. From this issue I’m handing over the editor’s reins to Stefan Richter whom I’m sure can give this old workhorse a fresh set of heels. It’s farewell from me – and I hope you’ll continue to support this great magazine. Glenn H. Baker Email:

Kiwi designed ‘no-fog’ safety goggles FIRST showcased in this magazine in July 2005, Safe-Eyes safety protection goggles from Kiwi Ideas Company are nowpoised to make a safety statement in workplaces around the world. Former forester Phil Hall, who heads the company and originally came up with the idea for Safe-Eyes after his forestry employees experienced fogging problems with traditional goggles, says they are about to enter the worldwide market for eye protection. “We’ve been in discussions with possible global distribution partners and we’re planning to provide a range of mesh goggles to suit as many industry applications as possible.” Hall has been steadily improving and enhancing the goggles since he first started making them in his back shed. The unique, highly durable mesh screens make them ideal for a number of industrial applications – everything from engineering workshops to joineries, water-blasting and weedeating – at last count there were 60 different industries that have found Safe-Eyes suitable.

Mechanical actuators provide precision positioning AT this year’s AIMEX exhibition in Sydney Enerpac is introducing its latest Uni-Lift mechanical actuators in capacities up to 250 tons. The B and M series Uni-Lifts – utilizing respectively ball screw and machine screw mechanisms with strokes up to 6096mm – are designed to set a new standard for linear motion control in precision positioning and control in a mechanical package. They are so accurate and reliable that, in addition to positioning heavy machinery and plant, they have been used in roles such as satellite dish positioning and solar panel tracking. Ball screw jacks, with load capacities up to 100 tons, are well suited for high-cycle, high-speed applications. Machine screw jacks, with load capacities up to 250 tons, are ideal for

low-cycle, high-load applications needing a self-locking load screw. Uni-lifts complement Enerpac’s extensive range of high pressure (700 bar) compact and powerful hydraulic lifting and manoeuvring technologies, which range from the new RC-Series Duo and other cylinders from one to1000-plus tons capacity, through to synchronous PLC-controlled systems that can lift bridges, drilling platforms and structures weighing tens of thousands of tons. Enerpac says its extensive line of Uni-Lift accessories allows for easy connection and precise synchronized control of multiple actuator systems. Tight tolerance thread forms, heat-treated gear sets, and pre-loaded bearings ensure repeatability and durability of these Go to linear actuators. enquiry quote: D110902a

“I can particularly see miners using them,” says Phil. “They work in hot, dusty and dangerous conditions and must keep their eye protection on.” Safe-Eyes goggles have nowachieved the UK, EU and US safety eyewear standards – complying with both BS EN 1731:2006 and ANSIZ87.1.2010. There’re around 4000 eye injuries at work each year in NewZealand. Wanganui emergency medicine physician, Dr Chris Cresswell says he frequently deals with eye injuries caused by industrial debris flying up and under standard safety goggles. “While trying my friend’s pair of Safe-Eyes when using a scrub-cutter I was immediately convinced of their value. I nowrecommend them to all patients with this type of eye injury and am working with ACC to get them recommended to local industries.” Safe-Eyes safety protection goggles are available from all Protector and NZ Safety stores.

Controller simplifies development of tube cutter

An advanced 5-axis motion control system from Baldor is key to the performance of the plasma tube cutting machine.

AN innovative new plasma cutting machine for flue pipes has been developed by Techserv Cutting Systems, a manufacturer of CNC profile cutting systems. Advanced interpolated motion

of the cutting system is used to dramatically increase production throughput – using an economic real-time machine control module from Baldor. Capable of cutting aluminium and stainless steel flue pipes at any angle, as well as holes of any shape or size, the plasma tube cutter completely automates this aspect of manufacturing. Until now, for example, elbow pipes have traditionally been produced by first cutting complex shapes from flat metal sheet, which are then rolled and welded before assembly. This multi-stage fabrication process necessarily involves considerable movement of work pieces around the factory and is very timeconsuming. The new cutter dispenses with the need to pre-cut complex shapes. Instead, the flat metal sheet is first rolled into a tube and seam welded, then each tube is successively loaded into the machine. The entire

cutting operation is handled autonomously; a simple angled cut takes a matter of seconds. Cutting the angled end pieces for an elbow pipe and then assembling them can now be accomplished in around four minutes. The tube being cut is mounted in the machine with its top end held in a rotating pneumaticallydriven clutch assembly. The plasma cutting torch is moved up and down as the tube rotates, at a rate which determines the severance angle or the size and shape of the hole being cut. Both the main rotational axis and the plasma torch height axis are powered by Baldor BSM series AC brushless servomotors driven by Baldor MicroFlex digital servo drives, and employ interpolation to secure a constant cutting rate regardless of the profile of the cut or diameter of the tube. The tube cutter also uses three Baldor stepper motor driven axes. Two of these control the position of a pair of guide rollers, which support the tube during the cutting process and are driven closer together or further apart depending on the diameter of

the tube. They also move aside automatically during the tube reload phase to facilitate operator access. The third stepper-driven axis dynamically varies the distance between the plasma torch head and the wall of the tube during the cutting process, to provide optimum performance. All five electrical axes are controlled by a Baldor NextMove ESB-2, a compact real-time machine control module which receives commands direct from an on-board PC-based CNC system developed by Techserv specifically for tube profile cutting applications. The new plasma cutter was developed for UK company Flues & Flashings. According to Gary Watkins, works manager, “The performance of the plasma tube cutter is superb. Changing the process so that we are preforming the tubes before cutting them, instead of cutting complex shapes from flat metal sheets, has enabled us to virtually quadruple manufacturing throughput.” Go to enquiry quote: D110904

Another grain processing plant ‘in the bag’ AFTER a significant change in operations, including the relocation of a grain cleaning facility and the implementation of a bagging plant, it is ‘mission accomplished’ for a Waikato-based grain supplier. But the successful outcome would not have been possible without the experience, knowledge and quality equipment supplied by Aurora Process Equipment. Aurora worked closely with the client to complete the project on time and within budget. The grain supplier’s requirements for the project were: • An infeed, plus a handling bin system for the internal transportation of grain. • Assisting conveyor system for moving cleaned grain to waste collection, crushing plant, bagging plant or mixing plant. • A 20kg bagger and automated sewing line. The experienced team at Aurora made recommendations and calculations to evaluate which equipment and systems would best suit the grain process and the available space. The team worked hard on the project – altering existing machinery, taking measurements, providing information and concepts, and constantly updating the client and ensuring they were at all times

satisfied. Aurora was awarded the contract to supply, install and commission all the necessary equipment to complete the project. The process equipment included: two ton portable handling bins, a cleaner frame and intake, cleaner discharge screws, crusher intake and discharge, two bulk bagging stations, a Floveyor elevator complete with an Aurora

Magnetics separator probe in the hopper to remove foreign metallic contamination, a nine ton vertical grain mixer, TE100 bagging scale, Fischbein mini system and conveyor, and a bag incline conveyor. The whole project ran smoothly with a few days of plant installation/adjustment and machine commissioning required. The client now has its plant

running at full production and is very happy with the outcome. “The whole project ran smoothly and any issues we had were handled professionally by Aurora,” says the client company’s project manager. Go to enquiry quote: D110905



Stress-free crane installation

WHEN Peter Wilson, director of Independent Tube Mills (ITM), started planning the company’s new purpose-built manufacturing facility in Melbourne’s western suburbs last year, he had no hesitation in specifying overhead cranes from Konecranes to do the heavy lifting. “I’ve been in the steel industry for around 30 years and I have used Konecranes and other cranes previously, but I’ve always found

Konecranes to be a better crane. They are not the cheapest, but they are the best,” Wilson says. ITM has invested in the very latest technology available in rolled steel manufacturing and went into production last July. “We have four cranes operating, all utilising Konecranes’ high performance CXT overhead cranes, all with advanced radio remote controls,” adds Wilson. “Safety is

a very important issue for us and our workers. That’s why we have installed Konecranes. They have a far superior quality than other cranes, and a great name for service and reliability.” He explained that the company has the capacity to produce 55,000 tons of steel tube a year, and needed to manoeuvre some very heavy loads around the facility. “The lifts can involve weights up to 17 tonne, and it’s far safer if the operator can stand at a distance from the load, controlling the crane by radio remote control.” “We utilise a CXT 20 tonne hoist, on a double girder, to unload the coils when they come in on the trucks. At present, we are averaging three B-doubles a day. “The coils weigh around 16 to 17 tons, and sit in a specially designed cradle. The crane picks them up and put them down in their respective place in the warehouse. With these cranes we can unload a truck easily within 25 to 30 minutes and load a semi within 40 to 45 minutes. “We also have CXT 16 ton crane to service the mill. It loads the coil

on and off the mill plus it can be used to service the bundler when needed; to quickly and efficiently remove any rejects. “A special 10 ton twin hook rotating crane from Konecranes picks material up off the transfer table of the bundler on the end of the mill. It rotates and brings the material down and stores the product in the warehouse. “The fourth 10 ton single girder has two 5.5 tonne CXT hoists attached, and actually picks up the finished product and loads the vehicles going out. At present we’re dispatching, on average, six to seven semi trailers per day.” “When it comes to maintenance, Wilson said he didn’t hesitate signing with Konecranes. “If a company manufactures something then you’d be crazy not to get it serviced by their people. There are lots of maintenance/service people around but I figure if you go back to the manufacturer they will understand the product in far Go to www. more depth.” quote:


Relays simplify safety device selection ANEWfamily of Allen-Bradley Guardmaster safety relays can help machine builders and end users simplify safety relay selection and reduce component inventory and life cycle costs. The line includes basic units capable of supporting a range of safety devices in various applications,


September 2011

such as single and multi-zone configurations. The relay line features a patented, single-wire communication capability that helps eliminate the need for dualchannel connection between relays. Users can expand and cascade safety functions up to a SIL 3 rating using

one single wire to connect devices. This provides a reduction in installation time and effort. In addition, “AND/OR” logic can be set via a rotary switch on the front of the relay, yielding a variety of configurations including regional and global e-stop architectures. Auniversal input feature allows devices, such as safety interlock switches, emergency stop switches and safety mats, to use the same set of input terminals on the relay. This helps eliminate the need to employ a specific safety relay for a specific type of input device, helping simplify system design and reduce hardware costs. The next-generation Guardmaster safety line also features dual-input modules, providing users with twice the functionality of a standard relay in a 22.5mm housing while reducing wiring for faster commissioning. A single TÜV-approved rotary switch with internal redundancy eliminates the need for double switches, helping to speed configuration while addressing

multiple functions such as reset modes and time delays. The Guardmaster family is designed to meet newfunctional safety standards such as ENISO13849-1 Go to www. or IEC/EN62061. quote:




Rotary screw compressors have their advantages ROTOR Compact series screw compressors from Industrial Air Systems promise a high quality, reliable and economic compressed air supply, says IAS director Nick Leonard. “Specification for specification and feature for feature, the Air Command RC screws come out on top when it comes down to analysing economical and reliable performance,” says Leonard. Air Command Rotor Compact screws feature the highly efficient direct-drive transmission system, normally only employed by much larger industrial screw compressors – which means utilising an over-sized air end, spinning at half the revolutions of the traditional belt driven screw model. Without any contaminating, wearing transmission belts, the RC screw runs much cleaner, and is fast and simple to service, says Leonard, which saves thousands of dollars in operating

costs over the compressor’s lifetime. Rotating at only 2900rpm (instead of 5000 to 7000rpm) the Air Command RC is very quiet running, and requires no noise insulation as found on any other belt-driven model. Unlike most rotary screw compressors, the RC model is designed to stop/start or run continuously – up to 100 percent duty cycle. This means it can be installed into most compressed air environments and only operates on demand, leading to power savings and reduced machine wear. The Air Command industrial RC screw compressor is available as a standalone or fully integrated model (screw, receiver, refrigerant dryer) in 7.5kW, 10kW and 15kW sizes – making it ideal for the one to seven man compressed air operation, in the automotive, engineering or manufacturing industry. One hundred percent European designed and manufactured, direct-driven Air Command RC screw compressors offer a very good investment for small industry wishing to improve efficiencies with a trouble-free clean Go to www.demm. compressed air supply. quote: D110908

The three operating modes let technicians troubleshoot, calibrate or maintain instrumentation with just one tool. The 750 Series features an easy-to-follow, menu-driven display that guides users through tasks. Programmable calibration

routines let technicians create and run automated as-found/as-left procedures to ensure fast, consistent calibrations. The recorded results can then be easily downloaded to a PC via the USB port, eliminating the need for manual transcription. Improvements over the original model include a graphical display that is nowbright enough for readings to be seen in any light condition. Another popular improvement is the new, rechargeable Li-ion battery pack, which provides enough power for an entire shift and can be charged from within the calibrator. The 754 model is the first field calibrator for HART instruments that is both powerful and easy to use. The 754 offers fast HART communication and requires no external box or secondary tool to perform everyday HART calibration and maintenance. The 750 Series works with the newFluke DPC/TRACK 2 software for managing calibration records and data. It features an instrumentation database

that makes it easy to manage instrumentation, create and schedule tests, load and unload the calibrator, print a variety of standard reports, and manage Go to www. calibration data. quote:

The best of oil and gas on display

(L-R) Swan Exhibitions operations manager, Keith Castellas, with New Plymouth Mayor Harry Duynhoven and Energy Publications account manager Mike Twiss.

SWAN Exhibitions, in conjunction with Energy Publications, the publisher of Oil and Gas Australia Magazine, recently completed yet another successful oil and gas event in New Plymouth. The New Zealand Oil & Gas Exhibition, held at the TSB Stadium from

August 10 to 11, marked its 17th year of operations in New Zealand. Officially opened by local Mayor, Harry Duynhoven, the event showcased the best of the local oil and gas industry and allowed participants to gain valuable industry leads

and contacts. Mayor Duynhoven said the exhibition displays were of a very high standard and the sundowners was very well attended with more than 100 people enjoying the hospitality. Exhibition organiser Keith Castellas from Swan Exhibitions said he was very pleased with the turnout of more than 60 exhibitors. “The general consensus among the industry was that the quality of visitation was of a high standard with lots of good leads and good business being done,” says Castellas. “We had the highest number of preregistered visitors ever and we had no complaints or environmental protests even though we were open to the public,” he said. This year’s exhibition had an international theme and attracted exhibitors from Russia, Canada, Indonesia, UK, US, India and Australia. Exhibitor Darren Deitz from Sensear said the event worked as a branding exercise for his company. “We were happy with the show, we had some quality visitors that will translate into some nice business for us,” he says. Honeywell HPS New Zealand attendee Dion Davidson said the event could not have been organised better. “The communication and professionalism from the start of the show was excellent. I would hope the event happens Go to again next year.” enquiry quote: D110914

Meeting peak demand

Two massive new energy projects are bringing energy consumers closer to optimal use of New Zealand’s renewable energy sources, while enhancing electricity generation flexibility and security. Jenny Baker reports. The gas-fired peaker plant from the air.

Contact Energy recently opened a new 200 megawatt gas-fired peaker plant near Stratford. On the same occasion it also opened an underground storage facility for natural gas near Ahuroa. Contact chief executive Dennis Barnes says the projects, at a combined cost of $420 million, are significant additions to Contact’s portfolio and important assets for both Contact Energy and the country. “The projects are also representative of Contact’s dedication and commitment to enhance New Zealand’s energy security in an increasingly volatile energy market,” he said during the opening ceremony. Although gas storage facilities are common across the globe, Ahuroa is the first natural gas storage facility constructed in New Zealand and as such posed a significant geological, engineering, and construction challenge for the company. But, says Barnes, Contact was fortunate “to be able to draw on the expertise of our majority shareholder, Origin Energy, to develop Ahuroa from a concept to a working asset.”


September 2011

A Contact Energy spokesperson explained to me the purpose of the gas storage and peaker plants and the challenging work that went into commissioning the two projects.

What is the purpose of peaker and gas storage plants? There are two types of electricity plants, base load and peaker. Base load plants operate continuously, stopping only for maintenance or unexpected outages. They generate electricity from geothermal, hydro, and wind energy (renewable sources) and from energy released by burning fossil fuels such as oil, coal, or natural gas (thermal sources). They take a long time to start and reach full operational power. The demand for electricity, however, varies widely, depending on time of day, weather and other factors. Peaker plants are generally run only when there is a high, or peak, demand for electricity. It ensures extra energy generation in times of high energy demand. Thermal energy, in particular

from burning natural gas, is the only energy source for a peaker plant. The Stratford peaker plant is capable of going from a cold start to full-power and producing enough electricity to power 200,000 homes in ten minutes, offering outstanding flexibility in its ability to meet spikes in demand. Gas production is a 24 hour enterprise, but demand for gas-fired base load and peaker electricity generation varies a lot, too, depending on how much electricity is being produced from renewable energy sources. A gas storage plant is a facility that provides storage of gas, so the gas can be injected into it during periods when it is not needed and withdrawn when it is. The spokesperson says approximately 70 percent of New Zealand’s electricity is generated from renewable energy sources: “This means the majority of our electricity generation depends on the weather. This weatherdependent generation needs to be backed up by reliable electricity generation, such as thermal,

which can be turned on when it is most needed.” Peakers in New Zealand therefore work not only during peak daily and seasonal demand periods, but also fill in the gap between what renewables can produce and what the country needs at any moment in time. “It is this thermal generation that keeps the lights on if the weather refuses to play its part,” the spokesperson says. In addition, meeting increases in demand with peaker plants means that larger combined cycle thermal plants can be used at a more constant, and therefore more efficient, rate to produce base load electricity. But even if the weather pulls its weight, renewable energy is abundant and demands for natural gas thermal power are lower, the Ahuroa storage plant now provides a way to better use natural gas. “The Ahuroa gas storage facility bridges the gap between the way gas fields would like to produce and the way in which the energy market likes to use gas,” the spokesperson says. Gas can now be stored during off peak


times such as summer and used during times when it is most needed, like winter, when demand peaks, or when fair weather impacts negatively on lake and wind levels.

Building the peaker plant The Stratford peaker plant is situated three kilometres east of Stratford on the site of Contact’s former Stratford power station, adjacent to the company's existing Taranaki Combined Cycle (TCC) power station, and nine kilometres southwest of the Ahuroa gas storage plant. The peaker is a 200MW gasfired, fast-start power plant. The stars of the plant are its two US-made 100MW General Electric LMS100 gas turbines, the first of their type to be installed in Australasia. The gas turbines are conventional aero-derivative gas units but with three important enhancements – a low pressure compressor, an intercooler, and a power turbine – that work together to increase the efficiency and power output of the plant. The total combined output of the two power stations at this site (the Stratford peaker plant and TCC) is 580MW. In March 2008, Contact signed a contract with United Group (NZ) Limited to design the plant, project manage, engineer and install the two peaking units, and procure and install the balance of plant required to complete the project. General Electric and

Contact engineers played a strong role in many of the design and build aspects. In September 2008, the foundations and subsurface work of the decommissioned power station were demolished. In January 2009 work began on driving 191 piles to an average depth of 11 metres. In June, the main foundations were poured by Fletcher Construction in an eight hour continuous pour with 180 concrete truck movements. In May the two Brush generators arrived from the Czech Republic at Port Taranaki on the Tampa, at 67 thousand tonnes the largest vessel ever to visit the port. Other equipment started to arrive on site from various locations around the world, notably Kobelco gas compressors from Japan, and Pauwel transformers from Indonesia. In July 2009, the gas turbines were positioned on their foundations. By June 2010, construction was completed and commissioning the plant began. In November the first unit was fired, and following a test period, the plant was opened on May 31 this year. The plant is designed specifically to operate within local compliance limits with minimal impact on the local community, and Contact spent more than $4 million to ensure this outcome. The model cooling tower the Stratford station uses is a hybrid wet-dry design. Its operation minimises the formation of visible moisture

plumes. A mixture of natural gas and high purity water are injected into the combustors. The combustion process produces the hot high pressure gases that drive the turbines. The addition of the high purity water reduces

the formation of nitrous oxide emissions. The power turbine that drives the generator is not mechanically connected to the other turbine shafts and can consequently deliver superior performance

even should there be disturbances in the electricity grid.

Building the gas storage facility The Ahuroa gas storage facility is a near depleted fossil fuel reservoir modified to receive gas for storage. Oil and gas were extracted from this field from 1995 until 2007. Contact Energy acquired rights to the field from American energy company, Swift Energy, in 2008 through the sale of their assets to Origin Energy. It is in a body of porous sandstone rock sealed in impervious layers of clay stone. To accomplish the conversion, a large injection compressor, gas processing equipment, and four injection-extraction wells had to be installed. Contact plans to store gas in it from a number of sources. The system is fully pressurised with sealed pipes. All four wells can be used for both injection and extraction, although Contact


September 2011

at present prefers to use two wells for injection and two for extraction. Isolation valves are installed at key points throughout the system so sections can be locked out if necessary. Extracted gas flows from the reservoir via a treatment plant into the transmission network. The treatment plant is similar to that used for conventional oil and gas production plants and removes water and oil from the gas. Contact contracted out the drilling, design, project, and operational management work to Origin Energy. Work to reconfigure the plant for injection started in June 2008. In May 2009, the new 2,000HP V16 Walker Shaw quad-turbo injection compressor, capable of 230 barg maximum discharge pressure, arrived in Port Taranaki. By the end of September, installation was completed, and in October 2009 the new compressor was commissioned.

In November 2009, drilling of the three new injection-extraction wells started, By March 2010 the job was completed and in July the coiled tubing rig was set up and well testing operations commenced. Transfield Worley Hawkins was engaged to engineer, procure and construct the gas extraction facility using a wide variety of subcontractors. In June 2010, site works commenced for the installation of an extraction train that enabled gas to be extracted at up to 45 terajoules per day – enough to supply the two fast-start gas turbine peaking units at Stratford power station – in addition to the existing injection capacity. In August 2010, the gas-to-gas exchanger and low temperature separator coalescer vessel were installed. Fitzroy Engineering from New Plymouth built the gas exchanger; Robert Stone from Auckland built the low temperature separator coalescer

vessel, and ITL, also from New Plymouth, provided the design services. By February 2011, the facility was fully operational, able to extract up to 45 terajoules/day of gas. The facility can be expanded with the addition of a second new injection- extraction train, and ultimately, could inject or extract up to 160 TJ a day if needed. The Ahuroa project won the award for ‘Innovation in Petroleum’ at the 2011 Deloitte Energy Excellence Awards, held on August 17 in Auckland. The Deloitte Energy Excellence Awards provide an annual opportunity to recognise excellence and achievement across the electricity, oil, gas and petroleum industries.

Skilled workers – will you find them? FINDINGskilled workers is set to prove a challenge for New Zealand’s engineering companies. Latest research from Competenz, the industry training organisation for the engineering and manufacturing sector, shows that skilled fabricators, tradesmen, welders and engineers are, and will continue to be, in short supply. In June of this year, Competenz asked 194 companies about their on-the-job training needs for now and in the future. Results proved that the skills shortage everyone is talking about is real, with 64 percent of engineering and metal manufacturers needing at least one more skilled staff member by 2013. To put this into perspective, New Zealand has 7,062 companies in the engineering and manufacturing sectors, meaning 4,519 skilled workers will be needed. Fiona Kingsford, GM of trade training at Competenz, says this is a real concern for businesses. “The reality is that engineering companies will need to upskill their existing staff or take on newapprentices nowto meet their current and future skills needs.” Companies knowthey have to train – 60 percent of all staff employed in the engineering and metal manufacturing sectors are trained on-the-job. However, it’s not enough to meet demand. Lisa Frost, training manager at John Jones Steel, a structural steel fabrication company in Christchurch says, “We need considerably more skilled welders and we are scraping to find anyone.” With demand set to skyrocket in Christchurch when rebuilding commences, a lack of skilled staff is a bleak prospect. Key areas of concern are fabrication, tradesmen, welding and engineering; representing a current skills shortage of 35 percent or 2,471 workers – and set to growby


September 2011

a further 2,542 workers in 2012 and 2013. The biggest shortage is for fabricators. Currently 444 fabrication apprentices are in training, but industry has said it needs 1,412 more fabricators in the next two years. Becoming qualified takes up to four years, so supply and demand is at a sizeable imbalance. With 49 percent of companies preferring to hire ready-trained staff, and only 18 percent hiring to train, recruiting skilled workers is not a viable option. Training is the best way forward, says Competenz. Whilst it is a considerable commitment, unless more businesses take on young learners and upskill their current staff, the skills shortage is inevitable. An option for businesses who do not want to take on the HR hassles of hiring is the ATNZ apprenticeship scheme. ATNZ eliminates the hassle for employers by recruiting, paying, mentoring, training and supplying the apprentice’s tools. Employers are provided the benefits of having an apprentice without having to handle the formalities. Staff already employed, yet never qualified, can gain trade certification via an assessment of prior learning, or APL. Designed especially for mature learners, APL assists individuals who missed out on qualifying earlier in life. The full report of the survey’s key findings and results, which covers the engineering and metal manufacturing sector and the food and beverage manufacturing sector, as well as ATNZ and APL apprenticeship information, is available on the Competenz website ( or as a hard copy on request by phoning 0800 526 1800.

Optimum results when welding aluminium THE Miller AlumaFeed synergic aluminium welding system, available through Weldwell NewZealand, is specifically designed to give optimum results when welding aluminium. The system is sophisticated but simple to operate and comes with a Miller True Blue three year warranty. Because aluminium wire is softer than most other welding wires, there are potential wire feed issues when MIG welding. This is overcome by the use of a push/pull welding feeder and gun. This makes use of the double feed system that pushes the wire into the gun at the wire feeder and pulls the wire via a drive motor at the gun handle. This enables the feeding of even a soft aluminium wire over extended distances. Push/pull guns are available upto 10.7 metres long. This gives the advantage of being able to weld at some distance from the power source and feeder and enables welding in difficult to access areas. The AlumaFeed system is capable of: • Pulsed MIG Welding – For reduced heat input, distortion control, reduced fumes, no spatter, good mechanical

properties and all position welding. • Synergic Pulsed MIG Welding – Allows one knob control of all pulse welding parameters. • Profile Pulse MIG Welding – Adjustable double pulse welding for a TIG weld appearance. • Non-Pulsed MIG Welding – For when reduced heat input is not required. • Arc Length Control – The arc length is adjustable and stays constant regardless of operator gun position variations. • Dual Schedule – Allows you to pre-set different welding parameters and quickly switch between them. • Hot Start – Eliminates incomplete fusion at the start of a weld. • Weld Crater Control – Eliminates crater defects at the end of a weld. The AlumaFeed system consists of the Aluma Power 350 MPa welding power source, XR-AlumaFeed push/pull wire feeder, XR-Aluma-Pro or XR-Pistol Grip push/pull guns.

Extraction equipment essential for health and safety

WITH an increasing emphasis on workplace health and safety, the use of extraction equipment has now become essential. Many industrial work processes create significant dust and fume toxins which have long-lasting and adverse affects on employees. Egmont Air has a huge range of fume extraction equipment designed to extract contaminants from processes in the workplace and create a clean, productive and healthy workplace environment. Egmont Air provides a total design-to-installation solution with its range of extraction equipment and industry expertise. A free on-site consultation offers an initial analysis of any industrial


September 2011

application and associated dust or fume issue. A solution and proposal is then designed by Egmont Air to provide a guaranteed performance result. Extraction at point of origin The secret to providing a clean and productive working atmosphere is 'extraction at point of origin'. Applying this principle involves an understanding of the work process and available extraction methods so that an effective system can be designed to extract the toxic dust and fumes before they reach the operators’ breathing zone and spread throughout the work environment. Egmont Air features the popular

Clean-go mobile extractor, which is a compact and versatile mobile unit suitable for eliminating toxic fumes, solvents, gases or vapours and returning the purified air back into the work area. Articulating Suction Arms also provide a useful method of capturing smoke and fume and offer manoeuvrability for varying work process applications. These popular wall mounted articulating arms can be used in a welding-bay situation or general workshop area. They are ideal for fume and dust applications, extracting fumes over an area of up to nine metres radius. In machine-shop situations Egmont Air recommends oil-mist

collectors. These extraction systems protect employees from breathing oily fumes and smog. They create a clean and safe working environment by preventing the build-up of dangerous oily residue which covers machinery, floors and finished products. Egmont Air also specialises in wood dust and shaving extraction systems for sawmills, joinery shops, kitchen-makers, boat-builders and associated wood-working trades. Many bag-house filters and fans are available ex-stock and can be specified for large or small applications. Go to enquiry quote: D110924



Fume arms with smoother air flow

EXTERNAL joints to allowa smoother air flowinternally is just one of the benefits of the fume arm range launched by NewZealand Duct & Flex at the snowed-in SouthMACHTrade Showin August. The range of fume arms – available in diameters from 76mm to 200mm have arm reaches varying from one to four metres, dependent on the model. Geoff Ebdon from NZ Duct & Flex did the research on a recent trip to Europe and says the quality and performance of the products he selected are excellent. “Fume arms remain a very economical, versatile and durable method of capturing impurities close to where they are released – welding, grinding, polishing, cutting, soldering and even chemical fumes,” says Ebdon. “In our core business of supplying modular ducting and flex, we are frequently asked for these products, so it is a natural addition to our range of more serious filtration systems.” Most fume arm manufacturers offer two types. The competitive cost models have the hingeing and articulation on the inside of the tubes. Only the more expensive models have outside articulation. Internal components are harder to clean, become coated or abraded by the particles being sucked up the fume arm and affect flow. “We decided to offer a complete

range with articulation on the outside of the tubes, giving a better ‘smoother’ air flowperformance and no problems with particles becoming trapped in the articulation mechanism,” says Ebdon. “The fume arms are manufactured in Europe and we will be following our policy of supplying quality products and the widest range of diameters, lengths and price points in the NewZealand market.” Every fume arm is supplied with mounting brackets and a throttle valve (normally an extra cost) and they are easy to position due to the ‘all around’ grab handle. There’s a stainless steel range which includes a stainless steel hood and stainless steel tubing – ideal for laboratories using chemical applications, and food and pharmaceutical industries. “There will also be a wide range of extending boom arms to give even greater reach and telescopic arms,” says Ebdon. “Lights are also an optional extra.” For specialist applications, the fume arms can fitted with US FDA or EU approved food grade flexible connections, high temperature (300ºC) or antistatic flex from existing NewZealand Duct & Go to www.demm.

Custom chopper deals to egg pulp FOR more than 50 years, the heavy-duty Vaughan chopper pump has been responsible for solving some of the toughest solids pumping problems in industry. Recently, Pump Systems Ltd, the Vaughan authorised factory representative for Australia and New Zealand were called upon to offer a customised pump solution for processing egg pulp containing large amounts of abrasive egg shells. As standard, Vaughan chopper pumps are supplied with a twosegment cutter bar fitted directly in front of a sharpened chopping impeller. For most industrial and municipal waste applications, this time-tested design has proven extremely effective when dealing with heavy solids and/or rag and other fibrous material that would normally clog other pumps. In fact, this design has been so effective, that every Vaughan chopper pump sold comes with a non-clog guarantee. This particular application was slightly different in that the egg shells needed to be broken down


September 2011

as small as possible prior to being processed. To achieve this, Pump Systems proposed a Vaughan E-Series model HE3G horizontal chopper pump fitted with a special four-segment cutter bar. The combination of this cutter bar and the HE3G’s four-blade impeller results in extra points of chopping per revolution and therefore a finer overall chop. In addition to this, the pump also comes with a special EC2 external cutter to pre-chop material as it enters the pump suction. Not only does the Vaughan chopper pump provide outstanding, non-clog solids handling and chopping performance, but in this case, due to the very abrasive nature of the egg shells, the heat treated and hardened components of the Vaughan chopper pump are also well suited to the application.

Valves deliver precision aeration control PUMP Systems recently supplied eight special Egger IRIS control valves to South Australia Water for a project at the Heathfield Wastewater Treatment Plant in Adelaide. The equipment, consisting of one DN125 and seven DN100 electrically actuated type valves are to be used for air control applications at the plant where precise flow monitoring is required. Quality manufactured in Switzerland, the unique IRIS valve by Emile Egger & Cie SA is based on the same design principle as the aperture of a camera, which is continuously variable to provide precision flow control. The Egger IRIS valve’s 0-100 percent continuous aperture with enhanced segment edge design combined with excellent regulation characteristics helps to maintain a central flow axis for outstanding, hysteresis-free performance. Non-clogging, self-cleaning and

Pumps engineered for pre and post-stressing THE latest Enerpac ZU4 hydraulic pumps, engineered specifically for pre and post-stressing, contain fewer moving parts and generate less friction than conventional pumps to give more power and reliability. The ZU4 A300 series stressing pump with its 1.25kWmotor increases speed of operation which reduces cycle times. Outstanding flowdynamics also mean the energy saving ZU4 class 700 bar electric pumps will stay on the job longer, run cooler and be easier to service when the need eventually arises, says Enerpac. Rugged workhorses such as the ZU448REA300 double-acting pump can be coupled with Enerpac post-tensioning tools for mono strand construction applications common on building, mining and infrastructure development sites. These single-acting PT and doubleacting DPT post-tensioning tools deliver 20 or 30 tons tensioning capacity when coupled with the ZU4408REA300, which features remote pump control and advance/ hold/retract valving. Compact and highly portable ZU4T Series electric pumps, weighing between 30 and 32kg, employ a 1.25kWuniversal motor

that provides a high power-toweight ratio and excellent low voltage operating characteristics. The motor is coupled with a totally newpump element design that reduces oil flowturbulence; producing an industrial workhorse with fewer moving parts, less friction and which requires 18 percent less current drawthan comparable pumps. Enerpac says the universal motor offers important jobsite benefits. One is a lowstarting current draw, much reducing the likelihood of tripping breakers at startup. Another is outstanding tolerance for low supply voltage – in contrast with bulkier, heavier induction motors, which tolerate under-voltage poorly and quickly overheat. The universal motor can operate satisfactorily from a long extension cord or portable generator. The pumps’ increased flow rates, reduced heat generation and decreased power needs translate into higher productivity and reliability for applications such as construction, crimping, cutting, fabrication, lifting, lowering, materials handling, maintenance, pressing, pushing, pulling and production and process engineering.

The pumps are ideal for use with Enerpac pre-and-post stressing technologies including: • Durable field proven mono strand designs in capacities from 20 to 30 tons with soft-grip ergonomic handles to reduce operator fatigue. • Single acting PTJ models incorporating newEnerpac posttensioning cylinders with 254mm stroke, ideal for slab-on-grade

applications. • Double-acting DA models with 216mm stroke, machined from a single billet with gun drilled internal hydraulic passages. • Re-useable and one-time-use barrels and wedges from five to Go to www.demm. 15.2mm. quote: D110929



Ideal pumping solution for sodium hypochlorite A HIGHLY corrosive and toxic chemical with strong disinfecting properties, sodium hypochlorite plays an important role in the water industry. However, its tendency to release gas bubbles and cause gas locking at the valves poses a major challenge to conventional pumping techniques. The UK’s South East Water has overcome this difficulty by opting for peristaltic pumping technology from Watson-Marlow. Sodium hypochlorite is a corrosive chemical that has disinfection and bleaching properties, and is used in the purification of wastewater and the disinfection of drinking water. However, dealing with the chemical can be difficult as it is toxic and emits chlorine when in contact with acids. It naturally releases tiny bubbles of gas, which have a tendency to collect on the small ball valves found in conventional diaphragm dosing pumps. This can cause gas locks in the system, which prevent the pumps from functioning. South East Water had been using diaphragm pumps to dose sodium hypochlorite into drinking water. However, they found that gas locking problems necessitated maintenance on a regular basis. When the pumps were replaced with 520U/R IP66 peristaltic pumps supplied by Watson-Marlow, this problem was eliminated. Peristaltic pumps have no valves, seals or glands and the fluid only contacts the bore of the elastomeric hose or tube. South East Water found that the gas produced by sodium hypochlorite was able to pass straight through the tube without interrupting the dosing process, thereby reducing maintenance dramatically. “We’ve worked with Watson-Marlow for years,” explains Ray Lawrence, process engineer at South East Water, “so we understood the value of their peristaltic technology, and decided to use it

in an innovative way. Because peristaltic pumps retain the fluid completely within the tube and have no valves that can leak or corrode, they can be used for the accurate metering of substances as challenging as sodium hypochlorite, without the associated gas locking and maintenance problems.” South East Water is also using the pumps for dosing sodium bisulphite, in order to de-chlorinate the water after disinfection to remove the unpleasant taste. The chemical is dosed in very small quantities, which requires a high degree of precision and accuracy from the pump. Previously, it had been necessary to dilute the sodium bisulphite in order to control

the dosage procedure accurately. This added an extra degree of complexity to the process, but Watson-Marlow’s 520U/R IP66 peristaltic pump resolved the issue. The pump can be calibrated either by weight or volume, allowing very precise dosing and metering. South East Water is now able to dose small amounts reliably even at low pressure, without the need for dilution. Watson-Marlow peristaltic pumps are represented in New Zealand by Watson-Marlow Bredel Pumps, based in Auckland. Go to quote: D110930

MAINTENANCE MATTERS The power of purpose

One of the most extraordinary programmes to facilitate and manage young school leavers into trade apprenticeships has been quietly gaining momentum in South Auckland over the past three years. Editor

Year One 2011 cohort at MIT.

Glenn Baker talks to Trades At School founder and CEO John Kotoisuva. You don’t have to be a rocket scientist to figure out that there has long been a problem getting young school leavers to focus on trades careers after high school, or to recognise a tangible purpose for their high school education. Thankfully, there is a scheme up and running, albeit still in its infancy, that has the potential to make a real difference – to give young people that real sense of purpose and help solve NewZealand’s ongoing skills shortage in the trades. It all began when John Kotoisuva, during his time as a modern apprentice assessor and tutor with Apprentice Training NewZealand (ATNZ), saw

the disconnect between the education sector and industry. “Young people coming into industry after training did not quite meet the requirements of the employers. They lacked understanding of the culture and the language of industry, and were coming into jobs quite ill-prepared,” he explains. “It was evident to me that the preparation of young people for industry wasn’t good enough – and so the concept for Trades At School began to form in my mind. “At ATNZwe were having a high termination rate of apprenticeships,” recalls Kotoisuva. “I also sit on the advisory board of Competenz, representing the steel industry. At our last meeting it was revealed that

60 percent of newapprenticeship sign-ups terminate in the first 18 months. I believe this is largely due to industry not really being truly represented in the education sector.” Signing contracts was often a case of ‘trial and error’ for apprentices, he says. “They would ask ‘is this for me or not?’ Trying to cope, especially in the initial stages of the apprenticeship, was a tough, lonely process for many.” Meanwhile, says Kotoisuva, students are sitting at secondary school, Year 11 through Year 13, not knowing why they are there. “They cannot relate the subjects they are doing to life after secondary school.

They can’t personalise NCEAor be motivated by it.” So industry ends up getting young people simply with NCEAcredits from all manner of subjects, he says.

Building a bridge “Trades At School is about building a solid bridge between industry and the education sector and bringing industry into the classroom for what it really is – presenting it in its truest form. Trades At School, with initial five-year seed funding from the ASBCommunity Trust and Ministry of Pacific Island Affairs, has already put runs on the board. Working with 11 secondary schools in South Auckland and the Manukau Institute of Technology (MIT), the three-year programme has already had its first intake graduates. 14 achieved the National Certificate in Mechanical Engineering Level 2 (NCME L2) – a tertiary qualification additional to their NCEALevel 2 and the equivalent of a one year apprenticeship for ten different trades. Furthermore, seven students have already found trades employment – even those that haven’t were still motivated and confident enough to go on to pursue other careers. There are no negatives in this scheme – only positives! The benefits to all parties are plain and obvious. Students become focused, motivated and, most importantly in this age of high youth unemployment, they have far greater earning potential at a young age. The schools benefit by having more engaged, high-achieving students with positive attitudes and behaviour – they can see a

purpose in their studies. Employers gain groomed, more productive workers with the right skill sets and the right attitude. There’re reduced training costs for them too because Year One apprenticeship unit standards are completed with the trainees attending MIT one day a week (three terms a year for two years). The trainee already has a two year track record (commitment) from secondary school and work experience in industry during the school holidays. And let’s not forget the macro socioeconomic benefits – less welfare dependency, minimised teenage joblessness and negative social behaviour, less need to bring in overseas trained workers, the list goes on. It’s no wonder John Kotoisuva wants the scheme to roll out from its current focus on mechanical engineering (fabrication/welding, precision engineering and maintenance) to other sectors – such as building and construction, rigging and scaffolding, manufacturing and infrastructure. “The simplicity of the programme makes it so easy to duplicate.” It’s also understandable that he wants additional support beyond the current five year timeframe – more buy-in from business leaders, employers and funding agencies. “With support from employers especially, Trades At School simply couldn’t function,” he says. “This is a home-grown human resource – your vehicle for the next generation of skilled workers.

We’re still losing far too many skilled workers to Australia. We must generate the numbers of new graduates and keep up the quality – and work at keeping these workers here with their extended families.” Kotoisuva is excited about the potential of the programme long-term. Trades At School deserves consistent funding in years to come, he says, if it is to successfully respond to the needs of industry. No more ambulance at the bottom of the cliff, he says. “This is not about throwing lifejackets to save young people – it’s a prevention programme. “It’s about empowering young people and walking beside them – helping them to cross that bridge between secondary school and employment, apprenticeship and traineeship. “Trades At School helps young people make the transition with pastoral care and mentoring, education and exposure to industry, into productive jobs in an industry of their choice.” Kotoisuva has an experienced board backing him, and a ton of positive testimonials from students and employers already to prove that this scheme deserves greater recognition.

How tHe programme works Trades At School comprises the following three stages: 1. Pre-Trades At School – Year 11 students are introduced to the programme through industry experts sharing their experience in the classroom and through on-site tours. 2. Trades At School – Year 12 and 13 students attend polytechnic one day a week for three terms over two years to complete the NCME L2 with more than 60 credits on top of their NCEA. 3. Post-Trades At School – Students exit secondary school and are supported through mentoring, pastoral care, career planning and assessing, and in industry through employment, apprenticeship, traineeship or higher education.

Only an electrical ANYtime a part is machined, the oil, grease and chips from the machining process need to be removed before further part production takes place. Otherwise, residue and chips inhibit later manufacturing processes, whether they are performed in-house or off-site. As many manufacturers can attest, it can be a challenge to clean machined parts to tight specifications in a cost-effective and environmentally sensitive manner.

Manual parts cleaning is not only cost- and labour-intensive, it also poses a risk for the operator’s health. With the EMC Jetsink Cleaning Station, Dimac Tooling nowoffers an automatic alternative to manual solvent wash tanks.

Understanding reliability centred maintenance

The MSG process originally developed for the Boeing 747 was adopted by the wider aviation industry and later adapted for use by general industry and renamed ‘Reliability Centred Maintenance’. TRADITIONAL thinking that equipment failure can be determined by length of time in service is severely flawed, as most readers may be aware. Research carried out by the airline industry and US Navy found that the traditional bathtub curve could account for only four percent of failures. It was established that there are in fact six common equipment failure patterns and when all failures are considered, only around 15 percent can be determined based on hours or cycles run. This means that carrying out

scheduled replacement or restoration tasks based on hours or cycles run is inherently wasteful. It is our role within maintenance to ensure the reliability of all assets, and to achieve this we must consider methods beyond simply setting up time-based scheduled repair or restoration tasks. One of the tools we can use to determine the correct maintenance for any asset is Reliability Centred Maintenance (RCM), which grewout of the aviation industry. When the Douglas DC8 was in

service back in the 1960s, around four million maintenance manhours were expended between major 20,000-hour overhauls. With the introduction of the Boeing 747, a far more complex aircraft, it became obvious that a different approach was needed. This realisation prompted the industry to put together a series of ‘Maintenance Steering Groups’ (MSG) to re-examine everything they were doing to keep their aircraft airborne. After much research and development a process was formed with a maintenance focus, based on the function and failure effects of components. This process, known as MSG2, was released in 1970. The outcome was spectacular – the MSG maintenance programme on the 747 expended only 66,000 manhours between major 20,000-hour overhauls, and this on a far more complex aircraft. Unsurprisingly the MSGprocess was adopted by the wider aviation industry and shortly after by the military. In the early 80s the process was adapted for use by general industry by John Mowbray. It was renamed ‘Reliability Centred Maintenance’ (RCM) and has since been used successfully the world over.

RCM analysis Reliability Centred Maintenance enables the definition of a complete maintenance regime for any asset taking into account the context or environment in which it operates. The initial part of the RCM analysis is to identify the operating context of the machinery, and write a Failure Mode Effects and Criticality Analysis, or FMECA. During this process the function(s) of the equipment is clearly defined and the ways in which it could fail to meet each function is considered. All possible causes of the failure (failure mode), and the effect that failure will have, are determined before the final part of the FMECA process, which is to consider the criticality of each failure mode. The second part of the analysis is to apply the decision logic which is used to determine the most appropriate maintenance tasks for the failure modes identified in the FMECA. Once the logic is complete for all elements in the FMECAand all maintenance tasks have been identified, the resulting list of


September 2011

maintenance is packaged so that the periodicities of the tasks are rationalised to be called up in work packages. Sounds simple enough! So why isn’t it carried out more widely? The reality is that to carry out an RCM analysis is a time consuming and detailed process, and requires a deep understanding of your equipment and the RCM process itself. Depending on the maturity of our current maintenance culture, bigger gains can also often be made by concentrating on the basics such as tightness of fasteners, lubrication, cleaning and alignment. However, there should come a time within all organisations when RCM is the most appropriate way to progress reliability to the next level. Working on the premise that a little knowledge is a dangerous thing, the first step should be to obtain a thorough understanding of the RCM process through reading or attending a training course. This will allowthe assets that are most likely to benefit from RCM to be identified and then provide the skills needed to get the process underway. Reliability Centred Maintenance is a high level maintenance tool that will determine the most appropriate maintenance for any asset, taking into account the context or environment in which it is operating. It will not increase reliability if we are not paying attention to the basics, but used in context it has the potential to reduce the amount of man-hours we expend on maintenance, while greatly increasing reliability.

What’s happening with our trades? Part one of a two-part series in which MESNZ secretary Craig Carlyle shares his views on the supply of tradesmen and training of apprentices in New Zealand, based on the Society’s survey results.

Regular readers of this magazine will be aware that the Maintenance Engineering Society (MESNZ) has given itself the task of discovering what is happening with the supply of tradesmen and training of apprentices in NewZealand. Focused by continuing unrest in the media, our epiphany was to look for solutions rather than simply add our grumbles to the debate. We could have relied on our collective experiences and opinions as a bunch of grumpy old men, but instead we resolved that we should learn as much as we could about the subject and gather as much industry opinion as possible. This was achieved with an Internet survey and interviews with industry players, suppliers, employers and identities. While the MESNZ strawpoll survey professes no professionalism in research methods (hell we are only dumb engineers!), the results are conclusive enough that to deny that an issue exists would be to declare that there is no elephant in the room. Fewwould argue that our trades force nowcommands the global respect that it was once famous for. Either in engineering or with trades roots in engineering, Kiwis were

held in awe for their abilities and achievements. Yes, the world has changed, but why have we slipped from our pedestal? To understand the global perspective, I spoke at length with Ross Green, a Kiwi engineer whose global company, Drivetech, chooses to maintain a presence in New Zealand. As Ross puts it, in the 1950s we were ‘king of the world’, based on our investment in infrastructure and technical competence. We suffered hugely in the 1970s at the whim of global economies and have looked like a possum caught in headlights ever since. We nowcongratulate ourselves on our booming tourism industry without ever considering that the future of that industry can already be seen in places like Bali and Phuket. The result of the dumbing down of industry places great pressure on companies like Drivetech. The arguments for retaining a presence in NewZealand no longer hinges on our engineering base; the skills are not just getting harder to tap into, they are disappearing. Global industry is about NOW, with the transition from concept to tooled prototype measured

in days, not weeks. The only (perhaps romantic) reason for Ross’s company still connecting with NewZealand is our value as R&D innovators. Ross points out that NewZealand is the best country for inspired culture. We have an ideal market testing environment with pocket sized cities and increasing Internet connectivity. From an R&D point of view, we should learn from the infrastructure of Boston and ensure our entire education system is geared to once again generate craftsmen that lead world standards. Where our relative success in history has stemmed from our emphasis on science, (Rutherford), we need to place greater emphasis on converting science into wealthgenerating products and services. Take the iPhone, for instance – the infrastructure behind developing such technology and tooling could easily have come from NewZealand. As Ross puts it, “It is often the 71st idea that is the best and no-one is better at generating those ideas than Kiwis.” Unlike other countries, our culture allows us to make suggestions without losing face. Our problem is that we can’t finish the idea and the

skills to turn ideas into reality are disappearing. Ross does not have a labour cost issue in NewZealand; his issue is that there is no longer a labour supply here in the specialist skills that he requires. He also points out that as we lose the skills (for example, our Air Force strike force and associated sub-skillsets) we will never get them back. Ross puts his finger on the societal aspect. In the world’s leading economies, trades skills are respected and represented, right up to board level. Craftsmen have enviable status in industry and newrecruits clamour to obtain trade skills. Economies are based on entrenched value and depth, not stripping industry to match third world labour rates. In NewZealand, we have evolved into a commodity supplier, sitting on our hands thinking “We are clever, we are innovative”. Unfortunately other countries are clever too, but they also work longer and harder. Ross points to leading economies as a pointer to a culture change. Today’s major economies like Japan and Germany were built on the back of post war US investment. To expect that kind of investment here is wishful. What is needed from our politicians is the


to fully understand what stands them apart from other tertiary or professional training; cadetships, diplomas and degrees. We asked tradesmen if there is a fundamental difference between an apprenticeship and other forms of technical/professional training? The result was an overwhelming 88 percent – who said YES! Comments included: “Apprenticeships are an effective way of developing personal and work skills”, “Invaluable for transferring knowledge to the younger generation”, “An opportunity to practice and develop skills”, “Hands on training and mentoring”. My favourite comment though was: “Apprentices are taught from the start that efficiency, focusing on learning and applying correct skills and getting it right the first time are first principles in the trades. Poor work and scrap material can’t be hidden by clicking a button.”

Are schools doing the job?

testicular fortitude to map a path forward that is inspirational and achievable. Success is obtainable, look what Sir Peter Jackson has achieved for the film industry. While it took one man’s kahunas and backing, a visit to Miramar is evidence indeed of a whole newcraft pool supporting the success of one industry. Overseas, the skill base is valued, maintained and has evolved to include newmethods and materials. School leavers aspire to trades skills and only a small percentage move their focus onto degree level. The obsession of NewZealand Polytechs becoming “universities” can be compared with the British model, since rejected, which, in Ross’s words, “Simply generated third rate degrees. Ignore history at your peril.” Interesting comments from a man who employs engineers and craftsmen globally.

The tradesman’s view With Ross Green’s observations ringing in our ears, let’s take a look at what Kiwi tradesmen are saying. Our humble survey drew80 responses – 89 percent of whom were aged 36 and above. The majority (97 percent) were male. Our first survey questions to tradesmen revolved around the old apprenticeship board and its presence and value to them. The results showed that 60 percent had occasional to regular involvement with the authority; 67 percent had seldom or no site visits. We asked respondents what the authority did for them. The resulting comments fell into two groups: either companies were large enough to include their own in-house apprentice masters in which case the interaction was highly disciplined; or, for more humble companies, the apprenticeship authority was a ‘grey ghost’ that governed and only got directly involved when you were in trouble. Valuable commentary when we consider the “modern” replacement for the role of apprentice masters: our ITOs (Industry Training Organisations). While industry grapples with the number and funding of ITOs, the obvious questions should be: “Are ITO’s relevant?” and “Could the government get a better bang for its buck with an alternative method of managing apprentices?” The vast majority of tradesmen, 87 percent, rated block courses as vital or highly important to their trades learning. Comments included: “It made you much more aware of the available technology”, “You could measure yourself against your peers”, “Some guys really needed input from the tutors”. When it came to personal growth and maturing, 76 percent claimed that block courses were vitally or highly important. Feedback included: “Opportunity to discuss with peers our work environment, skills etc”, “The tutors provided the mentoring I needed to get my act together away from the workplace”. You need to complete an apprenticeship

With the knowledge that most of our respondents are nowparents of secondary age children, we asked if the way we are streaming, preparing or teaching school children through the school system is doing a better job of developing interest and preparing potential apprentices. “No” was the response of 84 percent of those polled. I wonder howthe respondent who stated that “the hands-on teaching of metalwork [at school] provided the seed that nowsees me managing complex, multimillion dollar projects” would have fared in the modern system! The modern apprenticeship system replaces the old hours-based version with achievement standards that generally occupy the same timeframe of three to four years. With the fiddling with apprenticeship hours in the 70s and 80s in order to turn out tradesmen faster, we thought it opportune to harvest our respondents’ opinions on the ideal apprenticeship length. Seventy two percent voted for 8000 hours, with the next popular choice (16 percent) suggesting 6000 hours. In our search for answers, we provided a 60 second opportunity to pass improvement suggestions onto John Key. The comments were prophetic: “Improve the linkage between schools and industry”; “Change the perception for young people”; “Incentivise the apprenticeship scheme.”; “Influence a culture change towards recognition that working with one’s hands can be exciting and profitable.”; “Introduce basic trades training in schools”; “Get back to basics”; “Return to the old system”; “Remove the ITOs.” My favourite? “You can’t learn howto sharpen a drill bit using a computer.” Wow! Unless tradesmen have a particularly bleary viewof the world, no amount of spin doctoring is going to convince this group that we are doing an equally good or better job of developing newgenerations of tradesmen. In part two next month, I’ll report on the survey responses from employers and trainers, identify ‘the elephant in the room’, and share some positive suggestions from the workshop floor.

Early peek at National Maintenance Engineering Conference papers By Craig Carlyle

WITH the November 2011 National Maintenance Engineering Conference now rapidly approaching, pressure is mounting on the organisers to reveal the speaking program. Whether to justify attendance or a specific search for solutions, the speaking program is always eagerly anticipated by prospective attendees. This year has seen no reduction in the pressure to deliver and speakers facilitator (and MESNZ chairman) Barry Robinson has finally shown his hand with the first release of the 2011 program. Featuring an eclectic mix of international, expert and peer speakers, this year’s program is well worth the wait – satisfying the ethos of reality-based maintenance management topics and the Society aim of raising the bar of maintenance engineering in New Zealand. From the opening root cause analysis paper of Assessco’s Timothy Smithson, the twoday conference will also feature papers on counterfeit materials, ultrasonics, employment law, earthquake engineering, variable speed drives, lean manufacturing, naval maintenance,

training and qualifications, machine tool alignment, case studies, computerized maintenance management systems, chemical safety and HASNO. Guests such as Commander Robert OchtmanCorfe of the Royal New Zealand Navy join perennial favourites such as Charles Willmot (IPENZ) to deliver a balanced mix of peer experience and expert learning. The speaking program is designed to inspire attendees and arm them with the maintenance engineering tools to take back to their own workplace.

Jewel in the crown The National Maintenance Engineering Conference is being held at The Distinction Hotel in Rotorua on November 9 and 10. Backed for yet another year by industry sponsor Hydac, the event presents a popular format of thought provoking papers, while providing ample breakout opportunities for engineers and suppliers to explore solutions to their particular issues. The annual conference is the jewel in the crown of the Maintenance Engineering Society

of New Zealand, (MESNZ), a technical group of IPENZ. Exhibitors too, will be pleased with the opportunity to get in touch with engineers over the two day event and the pre-conference Trade Expo. Entry level small business exhibition opportunities are priced from $550 plus GST. The attendance fee of $680 plus GST per person removes traditional hurdles for engineers normally prevented from attending comparable two day events by costs far in excess of this. The 2011 event goes further still, however, with the introduction of a $400 plus GST per person ‘bring a buddy’ rate for second and subsequent staff members. A better bang for your buck will not be found anywhere else for such an inspiring and informative event. Registration forms and background details can be found on the Society website at www. Or for further details, contact Leanne Powley on 09 296 1333, or email

Engineering creativity is Crighton’s competitive edge

In front of the production line are John Almond of Mechanical Support Systems (left) and Crighton GM Mike Grunig.

BYfocusing on creativity and a culture that emphasises thinking outside the square, Onehungabased metals engineering company Crighton is showing that it is possible for small, but smart, New Zealand companies to go toe to toe with the best of India and China and still come out tops. Having just launched its new branding ‘Engineering Creativity Everyday’, Crighton is living and breathing its competitive edge to the extent that clients are finding a better return on investment by keeping their manufacturing work here in NewZealand. Crighton GM Mike Grunig says the rebranding process was very useful because it led to some real soul searching. “When we took a step back and

had a real good look at ourselves, we realised our focus on creativity, our inclination to work as a team and to look at newand innovative ways to design and manufacture a product really set us apart.” One example is prominent New Zealand agricultural technology company TruTest, which took the production of its pigtail electric fence post range away from China and gave it to Crighton. As a result TruTest reduced its cashflowfrom eight months negative to just one month, while also slashing months off their lead times. Procurement manager for TruTest, Gary Walford, says the manufacture of pigtails – a fundamental farming item – was moved to Crighton because the company came up with a solution that produced the

same product as China (at a very similar cost), but with far superior manufacturing flexibility. “Crighton did a lot of pre-work on gearing their production line up to turn things around quickly. In addition, when we placed an order, they could customise to our size or style requirements.” When Mechanical Support Systems – a company specialising in the design and installation of electrical cable containment – required a cost effective cable tray range to be manufactured, they initially looked to China. Director John Almond says time is a huge factor in their business, as is the quantity of stock they are required to keep on the shelf. “Availability of stock can sometimes be the difference between

winning and losing a project.” Crighton was able to manufacture one of Mechanical Support Systems core product ranges for prices comparative to what those in India and China were coming in at. “This is unusual,” says Almond. “They did it by thinking a bit outside the square – they could also see the value in a product, and where they could potentially bring themselves into a newmarket. “Tenders happen on a very tight timeframe. For example, in construction situations – like the Victoria Street Tunnel – the call for our product is left to the last minute and we need to be able to meet that demand; to put huge quantities together in a very short time frame. Without Crighton’s support, we wouldn’t be able to do that,” says Almond. Abonus is not having to deal with language differences, time zone differences and consistency of quality. As a result of Crighton’s willingness to think outside the square, MSS can nowdeal with spikes in demand for any one of the products in their range. Mike Grunig says the biggest satisfaction for his company is surprising the customer and going beyond what they expected. “We take an analytical, practical and creative approach to understanding what the client wants to achieve and whether they’ve identified the best solution at the right efficiencies.”

New literacy assessment tool THE Department of Labour has developed a new tool called ‘Take the Test’ to help employers assess the literacy skills of their workforce. Take the Test is a leaflet designed to help employers work out (in just five minutes) if a business is affected by poor workplace literacy and numeracy. Department of Labour, Skills Highway



information and promotion manager Lisé Hutcheon says “It collates the basic data a manager needs to talk about literacy and numeracy issues with colleagues. An employer might find reading is a particular issue in the workplace. Alternatively, he or she may find writing, maths and oral communication are crucial skills gaps. Overall, we want employers to use Take the Test to measure the issues, as

well as think about ways to address them.” Check out Take the Test and read more about skills training online at www. Take the Test is available online (as an e-book) and in hard Go to copy. quote: D110940

Cheap steel imports costing local jobs NEWZealand’s structural steel industry has come out strongly in support of a newreport from the NZTE-backed Industry Capability Network (ICN) which found local firms, and the wider economy, would benefit significantly from their improved participation in procurement processes for large-scale projects. Steel Construction New Zealand (SCNZ) manager Alistair Fussell says it should be mandatory for NewZealand steel firms with appropriate credentials to be considered as potential suppliers for major projects. “The reality is that too many procurement decisions for major projects in both the public and private sectors are based on price. This has seen imports of cheap fabricated steel tripling over the past five years. “Our analysis shows that in the

year to 2009, steelwork imported into NewZealand increased by $43 million, resulting in the loss of more than 150 jobs in the steel construction sector, as well as the associated tax revenue. “We fully support ICN’s development of Local Industry Participation Plans for major projects, but at present these are just voluntary guidelines. We believe the time has come for the Government to make the guidelines mandatory and help to growlocal industry.” Fussell says it is generally accepted that heavy engineering is of strategic importance to sectors including oil and gas, energy, infrastructure, manufacturing and defence, but the economic importance of local fabrication is often overlooked by those who make procurement decisions. “In the case of the public sector,

Government purchasing decisions are meant to be based on a whole-of-life approach, in which the true costs of a procurement decision are considered over the planned life of the product or service. Our concern is that this is not happening. “Lowest-cost purchasing decisions are invariably the most expensive option when whole-of-life criteria are applied. Unplanned additional costs are likely to arise associated with poor design, sub-standard materials, late deliveries, low-quality fabrication, inability to correct errors, and penalties incurred for project delays. “What’s more, all too often overseas competitors don’t followour high standards of safety; many have never heard of sustainability; often subsidies and special procurement conditions apply, which amounts to dumping; and what they pay in wages is well

belowwhat we would regard as fair.” Fussell says it is important to understand that SCNZis not asking for preferential treatment for local industry. He says local industry deserves a level playing field. More effective public sector procurement practices would see government entities working with local suppliers to build local capability and develop innovative solutions, according to Fussell. “If the Government takes the lead, the private sector will follow.The result will be local firms increasing their capability and capacity, and producing export-quality products. It should be our common goal to build competitive industries, but we won’t achieve this if we base our procurement on finding the cheapest option.” The ICNreport is available at

‘Hands on’ engineering qualifications launched THE Institution of Professional Engineers (IPENZ) and the New Zealand Board for Engineering Diplomas recently celebrated the launch of the New Zealand Diploma in Engineering (NZDE) and Diploma in Engineering Practice (NZDEP). The two Diplomas are key outcomes of the National Engineering Education Plan project. The NZDE is an applied academic qualification offered through a number of Tertiary Education Organisations, whilst the NZDEP is a work-based qualification achieved on the job

through an Industry Training Organisation. Students can choose to complete the NZDE full time and then enrol in the NZDEP once they commence work, or take advantage of increasing numbers of industry cadetship programmes, which enable concurrent progress towards both qualifications while working. Forecasts predict a sustained demand for increasing numbers of skilled technicians, particularly in the infrastructure and manufacturing sectors. For some time, industry has been calling for technician-level qualifications that combine quality academic

study to national standards with rigorous assessment of practical skills “The unified New Zealand Diplomas in Engineering and Engineering Practice are practical qualifications which is why we have branded it as a Hands On Career” says Fulton Hogan Group

Civil Engineer Lindsay Crossen “Technician qualifications have proven to be a good place to commence a successful career and employees with knowledge and practical experience have measurable benefits in both quality and productivity”.

Energy efficiency training for RHAC specialists THE IRHACE Industry Training Charitable Trust (IITCT) and Energy Efficiency and Conservation Authority (EECA) have co-funded the development of four online web based training courses to provide high quality industry training to improve electricity management and efficiency in the Refrigeration, Air-Conditioning and Heating Services Industry. The courses are aimed at: • Commercial Refrigeration and Air Conditioning Service Companies. • Industrial Refrigeration Service Companies. • Heating, Ventilation and Air Conditioning

(HVAC) Services Companies. • Commercial Refrigeration and Air Conditioning Design Engineers. The courses focus on equipment, systems components and newtechnologies relevant to the particular industry sector. Topics include air conditioning and air handling systems, refrigeration, water handling systems, automatic control systems and aims to give participants ideas and tools to: • Help identify opportunities for saving energy • Explain in practical and numerical terms the reason why the matter is important.

• Show some of the design methods and procedures that lie behind a good system. • Assist in deciding what should be done to improve the system. It is hoped that this knowledge will allow staff to more-confidently raise issues with other staff and clients. An IITCT and EECACertificate of Attainment in Energy Efficiency is issued to attendees who complete the course and pass the assessment. To find out more email debbie@ or visit

SouthMACH2011, held in Christchurch on 17 and 18 August, was once again a success despite appalling weather conditions unseen in NewZealand for more than 50 years. SouthMACH2011 was a great achievement, with 90 of the 95 exhibiting companies participating and more than 450 of their exhibiting staff working hard to create a professional and polished event (despite the snow), attracting a good quantity of trade visitors over the two showdays. The visitors were highly impressed by the range of innovative and newtechnology on display at NewZealand’s only engineering, manufacturing technology and machinery event for 2011. More than a static trade show, SouthMACH11 featured three streams of ‘Focused on Industry’ seminars and workshops run by exhibitors and the NewZealand Manufacturers and Exporters Association (NZMEA). The seminars and exhibitor workshops covered a range of topics designed to keep visitors up-to-date with new and emerging technologies and were extremely popular. Seminar attendance was high, a direct reflection of the quality and variety of topics that were offered. Visitor surveys were conducted by TouchScreen Marketing and all visitors to the showwere asked to complete a short survey upon departure to provide feedback on their show experience. The results of the survey showed that 89 percent of visitors rated the showvery good or excellent, and 95.2 percent of visitors were intending to visit the showagain in 2013. “We were extremely pleased with the quality of the visitors to the show, and that exhibitors were happy with the contacts and sales generated,” says exhibition director, Rachel HobbsPrice. “SouthMACH was postponed originally from May due to the earthquake. And then a snowstorm, the worst since 1945 hit just as we were starting to build the show. The fact that the exhibitors still managed to build the showand the visitors still turned up in great numbers just goes to show howwell respected this event is.” The organisers, HayleyMedia, wish to thank all exhibitors and visitors for making the showterrific despite the many obstacles that could have jeopardised the fourth instalment of what has become an important reference point for the industry. “Onwards and upwards for SouthMACH 2013!” says Hobbs-Price.
