Dear Readers,<br />

Have you ever wondered how <strong>to</strong> drill a hole in<strong>to</strong> a mountain If so, the s<strong>to</strong>ry of Martin Herrenknecht and his<br />

<strong>rock</strong>-eating submarines might interest you. Maybe you were the kind of child who <strong>to</strong>ok grandpa’s mechanical<br />

alarm clock apart <strong>to</strong> see how it works In this case, Rudolf Neumayer and his Tear Down Centre could be just<br />

what you are looking for.<br />

What we would like <strong>to</strong> do in the first issue of “<strong>Loctite</strong> ® at work”, our new cus<strong>to</strong>mer magazine, is <strong>to</strong> take you on a<br />

journey behind the scenes of some of the world’s most successful and sophisticated high-tech companies. This is<br />

why we gave this issue the title “Reliability at work”. We want you <strong>to</strong> share our fascination when we look over the<br />

shoulders of engineers constructing the world’s largest tunnel boring machines destined <strong>to</strong> drill the way through<br />

the Alps or building propellers that move tankers and cargo ships through the ocean.<br />

We believe that curiosity and an interest in how things work are the basis for creativity and innovation, two values<br />

that Henkel and the brand <strong>Loctite</strong> ® stand for. That’s why in the first issue of “<strong>Loctite</strong> ® at work” we are putting the<br />

spotlight on two out of the many companies that embody those values, <strong>to</strong> show how they can impact on the<br />

practice and the success of a business.<br />

In our Trend Report, we will track the evolution of energy over the last <strong>15</strong>0 years and give an outlook on how the<br />

future of this most important resource of all might look like. And of course, with Henkel and <strong>Loctite</strong> ® you'll ride<br />

shotgun in the Dakar Rally with the <strong>Loctite</strong> ® brand.<br />

So, lean back and enjoy the ride.<br />

Yours sincerely,<br />

Cédric Berthod<br />

Highlight<br />

Live from the 2009 Dakar Rally<br />

Meeting the <strong>Loctite</strong> ®<br />

“Desert Knights” in the<br />

Copiapo bivouac<br />

A cloud of dust on the horizon. A VW Touareg<br />

approaching at breathtaking speed. The <strong>to</strong>wering<br />

mountains and dunes of the Atacama desert rising up<br />

all around Copiapo, in the northern part of Chile. The<br />

Copiapo – Copiapo special is a pretty <strong>to</strong>ugh challenge:<br />

476 kilometers of the steepest dunes, deep sand and s<strong>to</strong>ny<br />

tracks. According <strong>to</strong> the drivers it‘s the <strong>to</strong>ughest one in the<br />

his<strong>to</strong>ry of the Dakar.<br />

The Touareg whizzes by only a metre away at <strong>to</strong>p speed,<br />

the air filled with the powerful roar of the new turbo-diesel<br />

engine, a sound that makes every off-road fan‘s heart beat<br />

faster. Next the field of competi<strong>to</strong>rs arrives hot on the heels,<br />

in rapid succession: the great Mitsubishi, Hummer and<br />

BMW X-Raid desert racers. And then, following a short<br />

distance behind, the monster trucks rumbling by, making<br />

the ground shake. Thick clouds of dust have engulfed the<br />

terrain. The Atacama desert is said <strong>to</strong> be the driest in the<br />

world, with places where it hasn‘t rained for 400 years.<br />

Conditions for the drivers are <strong>to</strong>ugh: Rough terrain, difficult<br />

navigation, extreme temperature differences and, most of<br />

all, the dry and dusty conditions, push all competi<strong>to</strong>rs <strong>to</strong><br />

the limit. Vehicles are continually subjected <strong>to</strong> hard shocks<br />

and flying s<strong>to</strong>nes, the steep dunes demand the highest<br />

level of performance from the engines.<br />

That day the stage finishes at the Copiapo bivouac, the<br />

northern most point of the rally. The “Desert Knights” –<br />

Henkel engineers, better known as the “<strong>Loctite</strong> ® Charlies”,<br />

are also ready for action: Jean Gaborit from France,<br />

Célio Rena<strong>to</strong> Ruiz and Demetrio San<strong>to</strong>s from Brazil. The<br />

Dakar Service Center, set up as a common platform for<br />

Euromaster, BF Goodrich and <strong>Loctite</strong> ® /Pattex, is easily<br />

visible from a long distance. <strong>Loctite</strong> ® banners are snapping<br />

in the wind – and the red Renault truck is parked in its<br />

slot. It is fully loaded with products for repairing all kinds of<br />

vehicle damages: Teroson plastic repair and window glazing<br />

adhesives, Pattex Power Tapes, and the indispensable<br />

threadlockers, sealants, retaining compounds and instant<br />

adhesives from <strong>Loctite</strong> ® , used for maintenance and overhaul<br />

of the mechanical assemblies on engine and gearbox.<br />

Just now, as dusk is falling, the Henkel Team is busy,<br />

working at full steam: many of the drivers coming “home”<br />

– mainly the private competi<strong>to</strong>rs not accompanied by a<br />

service armada of their own – urgently needing support<br />

<strong>to</strong> get their vehicles going again for the next day. “There<br />

were several difficult situations during this rally where<br />

my machine was quickly back in shape <strong>than</strong>ks <strong>to</strong> the<br />

<strong>Loctite</strong> ® Team‘s professional repair service. This<br />

helped me save valuable time when every minute<br />

counts”, says Miran Stanovnik, a Slovenian KTM<br />

rider in the <strong>to</strong>p 20, sponsored by <strong>Loctite</strong> ®<br />

since 2005.<br />

The Dakar winners<br />

The rally finished successfully on 18th January, with a great<br />

winners‘ ceremony in the heart of Buenos Aires.<br />

A double vic<strong>to</strong>ry in the car category makes VW the new<br />

hero of the Dakar: Both Giniel de Villiers and Mark Miller<br />

maintained their lead after Carlos Sainz‘ withdrawal from<br />

the race, and they were more <strong>than</strong> enthusiastic: “For sure:<br />

this is the <strong>to</strong>ughest rally in the world - and we had the<br />

best marathon team in the world! I am overwhelmed by<br />

the surge of feelings at the finish line”, as de Villiers put it in<br />

moving words, “I am proud <strong>to</strong> be part of it, proud of what<br />

the team has achieved”. And his team colleague, second<br />

placed Mark Miller, adds: “De Villiers is a great champion.<br />

He deserved <strong>to</strong> win! For me as an American it‘s a dream<br />

<strong>to</strong> finish the rally in second place, and finish as the<br />

best American. Our team did a fantastic job.<br />

We will gather new strength from this<br />

vic<strong>to</strong>ry!”<br />

Third position was claimed<br />

by Robby Gordon driving<br />

a Hummer, the eye<br />

Hummer H3 in action<br />

7.0 liter V8 engine. He lost ground <strong>to</strong> VW as a result of<br />

several roll-over crashes during the rally. In the interview<br />

he stated: “Our only goal was <strong>to</strong> make it safely across the<br />

finish line. And we did. The rally was an incredibly <strong>to</strong>ugh<br />

challenge. We will now work on improving the chassis <strong>to</strong><br />

get an even better result next year”.<br />

No room for error<br />

From modest beginnings, the company was founded as<br />

a shipyard for fishing vessels in 1912, Berg Propulsion<br />

has developed in<strong>to</strong> a multinational company constructing<br />

propellers for all kinds of vessels. Tankers, containers,<br />

cargo ships and luxury yachts, <strong>to</strong> name just a few, all rely on<br />

the experience and the craftsmanship of Berg Propulsion.<br />

The demands placed on the reliability and durability of<br />

Berg‘s CP (Controllable Pitch) propellers are enormous:<br />

Once the propeller is fitted <strong>to</strong> the vessel, alterations<br />

become extremely difficult and the propellers are in use<br />

for 25 years or more. There is no room for error, because<br />

the safety of the ship and the vessel depend on the quality<br />

of the product. Money is another aspect; every day that a<br />

ship has <strong>to</strong> remain in the dock for repairs costs the owner<br />

between $<strong>15</strong> and $20,000 a day, explains Berg‘s Managing<br />

Direc<strong>to</strong>r Anders Chris<strong>to</strong>ffersson. (see interview)<br />

global leader in adhesive technology, have a lot in common:<br />

Both started as family businesses with an emphasis<br />

on high-quality products and both have developed in<strong>to</strong><br />

successful companies operating on a global scale.<br />

Henkel had the opportunity <strong>to</strong> observe the production<br />

process at Berg‘s island plant. The gigantic propeller,<br />

with a diameter of more <strong>than</strong> 9 metre, dwarfs the men<br />

standing next <strong>to</strong> it. The shining bronze propeller blades<br />

appear almost menacing in their shining perfection. At every<br />

stage of the manufacturing process <strong>Loctite</strong> ® products have<br />

an important role <strong>to</strong> play: The threads of hydraulic pipes<br />

responsible for controlling<br />

the individual<br />

blades<br />

Family businesses gone global<br />

Technological progress has made its<br />

mark on every aspect of life, and the<br />

manufacturing process at the plant on the<br />

idyllic island of Öckerö is no exception<br />

<strong>to</strong> this rule. A lot has changed since<br />

Johann Wik<strong>to</strong>r Berg manufactured<br />

the first CP Propeller for a<br />

wooden fishing vessel in 1929;<br />

one of those changes is the use<br />

of Henkel‘s <strong>Loctite</strong> ® products.<br />

are retained with <strong>Loctite</strong> ® 638. They have <strong>to</strong> withstand<br />

pressures of more <strong>than</strong> 70 bar, which equals twice the<br />

force the blades will have <strong>to</strong> bear on the ocean.<br />

Developing tailor-made solutions<br />

The adhesive sealing has <strong>to</strong> create a hermetic seal<br />

after an hour, because then the hydraulic pipes are<br />

embedded in<strong>to</strong> the shaft. Another example for applied<br />

technological progress is the production of the<br />

spacer that protects the propeller‘s control units. The<br />

spacer is fitted <strong>to</strong> the units with 4 screws, locked with<br />

<strong>Loctite</strong> ® 243. “<strong>Loctite</strong> ® increases the reliability of our<br />

products. We co-operate closely with <strong>Loctite</strong>‘s technical<br />

department during the development and the production<br />

process” says Chris<strong>to</strong>fferson.<br />

Lars Andreasson, from <strong>Loctite</strong>‘s Industrial Engineering<br />

department explains: “We can assist the cus<strong>to</strong>mer by<br />

calculating the pressures the product has <strong>to</strong> withstand, for<br />

example. It‘s a form of team-work. Our goal is <strong>to</strong> assist the<br />

cus<strong>to</strong>mer by developing tailor made solutions.”<br />

The manufacturing process of ship propellers has come<br />

a long way. What is interesting <strong>to</strong> note about it, is the fact<br />

that there is something like a conspiracy theory about<br />

the origin of the technology. There is a possibility that the<br />

Englishman Francis Smith, who <strong>to</strong>ok credit for the invention<br />

was actually preceded by the Austrian enthusiast Josef<br />

Ressel. Unfortunately, however, that issue wasn‘t resolved<br />

in Ressel‘s lifetime and he never received the credit that in<br />

retrospect appears <strong>to</strong> be due <strong>to</strong> him. While technological<br />

progress is uns<strong>to</strong>ppable, like the co-operation of Berg<br />

Propulsion and Henkel on idyllic Öckerö shows, issues with<br />

intellectual ownership seem <strong>to</strong> be here <strong>to</strong> stay.<br />

Anders Chris<strong>to</strong>fferson, Managing Direc<strong>to</strong>r Berg Propulsion Technology AB<br />

What is your position at Berg Propulsion I am Vice President of our<br />

technical division Berg Propulsion Technology. And we are developing Berg’s<br />

products of <strong>to</strong>morrow.<br />

You use <strong>Loctite</strong> ® threadlockers and thread sealants <strong>to</strong> <strong>secure</strong> assemblies in<br />

the hydraulic system and in the propeller hub. Can you tell us more about the<br />

specific requirements applicable <strong>to</strong> these areas The requirements which our<br />

systems must meet are that they have <strong>to</strong> be sealed, and this applies especially<br />

for our hydraulic systems, they have <strong>to</strong> be pressure resistant. Then in our threaded<br />

assemblies we have <strong>to</strong> lock the bolts and screws against vibration loads.<br />

In which way can <strong>Loctite</strong> ® be of help in those situations <strong>Loctite</strong> ® increases<br />

reliability of our products.<br />

Why do you use <strong>Loctite</strong> ® products in this application This gives us a quick and<br />

easy assembly.<br />

Which products do you mainly use We use threadlockers 243 and 2701, for<br />

retaining it is 638 and 603.<br />

Which benefits do you get, besides the technical reliability We can reduce<br />

inven<strong>to</strong>ries for mechanical locking devices and we have fewer item numbers, which<br />

gives us big savings in warehousing<br />

Why is reliability so important for Berg Propulsion Reliability is important as Berg<br />

has safe and dependable products. Our cus<strong>to</strong>mers expect ship propulsion systems<br />

with highest availability at all times. If there is some failure in the propulsion system,<br />

the boat can no longer earn money. And in this case, we talk about high amounts of<br />

money. This varies from <strong>15</strong> – 20 thousand US Dollars per day. This is not unusual.<br />

Do you make use of <strong>Loctite</strong>‘s technical service <strong>to</strong>day Yes, we use <strong>Loctite</strong> ®<br />

technical support daily in the form of calculations and application solutions. Then, we<br />

also get ongoing product training for our technicians and engineers.<br />

Do you know more about the brand <strong>Loctite</strong> ® , e.g. the his<strong>to</strong>ry or the other<br />

product ranges Yes, concerning the his<strong>to</strong>ry I know that it is a company from the<br />

50's, and we’ve started <strong>to</strong> use <strong>Loctite</strong> ® in 1964. It was a colleague, Erik Berg, son of<br />

the founder of Berg Propulsion. He was in England and came home with a <strong>Loctite</strong> ®<br />

product as replacement for the locking washer. And it worked. Since then we have<br />

used <strong>Loctite</strong> ® products and other products; those we know among others are your<br />

lubricants and flexible adhesives and instant adhesives.<br />

What do you think are the most important characteristics and benefits of<br />

<strong>Loctite</strong> ® products <strong>to</strong>day <strong>Loctite</strong> ® products have a lot of benefits. But the most<br />

important one for us is reliability and the technical support which <strong>Loctite</strong> ® gives us.<br />

10 | RD&E insights<br />

The s<strong>to</strong>ries behind inventions tend <strong>to</strong> have<br />

something romantic, something co-incidental about<br />

them: Archimedes allegedly had his big idea in the bath<br />

tub and Einstein is said <strong>to</strong> have been sunbathing in the<br />

park when the special theory of relativity occurred <strong>to</strong> him.<br />

If you listen <strong>to</strong> Martin Smyth and Peter Wrobel from the Henkel<br />

Technology Centre in Dublin, however, there seems <strong>to</strong> be little room<br />

for the picturesque co-incidents that make for a good urban myth about<br />

inventions.<br />

No room for myths<br />

It rather seems <strong>to</strong> be an efficient, well-organised process that leaves very little <strong>to</strong> chance.<br />

“We have something called Single Cus<strong>to</strong>mer Project, which allows us <strong>to</strong> react very quickly<br />

<strong>to</strong> cus<strong>to</strong>mer needs,” says Smyth. In this particular case, a cus<strong>to</strong>mer needed an adhesive<br />

that cured on nickel-plated substrate with an extreme speed. The initial screening phase<br />

<strong>to</strong>ok about a month. After another month, during which three employees of the centre in<br />

Dublin devoted themselves full time <strong>to</strong> the project, the first pro<strong>to</strong>type was ready. “It met 90%<br />

of their requirements, but it needed some fine-tuning,” says Smyth. By that point, market<br />

research had already shown there was a broader market for <strong>Loctite</strong> ® 276, the new addition<br />

<strong>to</strong> the <strong>Loctite</strong> ® product family.<br />

Co-adapting <strong>to</strong> industrial evolution<br />

Peter Wrobel’s s<strong>to</strong>ry is an example for a more long term project. It was a 2 year<br />

process that led <strong>to</strong> the development of <strong>Loctite</strong> ® 5188, a flange sealant aimed primarily at the<br />

au<strong>to</strong>motive industry. “We are basically co-adapting <strong>to</strong> the evolution of car engines,” says<br />

Wrobel. “There is a shift from steel <strong>to</strong> aluminum in the industry, and accordingly, we<br />

constantly improve <strong>Loctite</strong> ® sealants in order <strong>to</strong> work well with that material.” Before Mr. Wrobel<br />

and his team embark on such a project, though, there needs <strong>to</strong> be a solid business case. “If a<br />

successful commercial application seems less <strong>than</strong> probable, we don’t go in<strong>to</strong> the lab,<br />

because that’s very cost-intensive,” explains the team-leader. Wrobel is a trained chemist, but<br />

he has acquired a good feeling for the business side of things through cus<strong>to</strong>mer visits. While<br />

there is still a place for the coincidence and the power of the subconscious, after all success<br />

and failure is still down <strong>to</strong> people, individuals with their strengths and weaknesses, innovation<br />

depends <strong>to</strong>day on <strong>to</strong> a large extent on exact planning and efficient use of resources.<br />

High-speed threadlocker<br />

Achieving fast fixture on passive metal substrates – such as nickel- & other plated<br />

surfaces – is quite a challenge for an anaerobic threadlocker, especially if requirements<br />

also call for good sealing performance and high strength, as well as very good thermal and<br />

shock resistance.<br />

Finding the optimal solution: <strong>Loctite</strong> ® 276, one of the latest innovations <strong>to</strong> come out of the Henkel<br />

R&D labs, meets all of these requirements. Originally developed in as little as two months within the scope<br />

of Henkel's so-called Single Cus<strong>to</strong>mer Project in reaction <strong>to</strong> an urgent cus<strong>to</strong>mer need, the product was finetuned<br />

<strong>to</strong> give an optimal combination of characteristics for the market environment. And, there could be no compromise<br />

where performance was concerned, because a high production output is one of the key criteria.<br />

Reliability<br />

Benefits – Overview:<br />

• Provides locking and<br />

sealing<br />

• Ideal for gas pipes,<br />

valves & connec<strong>to</strong>rs<br />

• Allows higher<br />

production output<br />

Mission accomplished: <strong>Loctite</strong> ® 276 is a high-strength anaerobic threadlocker that achieves fast fixture even on<br />

passive metal substrates. It provides locking and sealing of threaded assemblies. It cures reliably even at low<br />

temperatures but can withstand up <strong>to</strong> +<strong>15</strong>0 °C. <strong>Loctite</strong> ® 276 carries the European gas approval according <strong>to</strong> EN 751-1.<br />

Available in 50 ml and 250 ml bottles.<br />

Flexibility – a challenge in gasketing<br />

<strong>Loctite</strong> ® 5188, the first anaerobic gasketing material<br />

offering excellent flexibility even after heat aging, can be<br />

used for many applications in the au<strong>to</strong>motive and industrial<br />

area. Typical applications include metal-<strong>to</strong>-metal flange<br />

assemblies such as gearboxes, housings, covers, etc.<br />

Anaerobic gasketing technology has revolutionised flange<br />

sealing of rigid flanges in the au<strong>to</strong>motive industry, and the<br />

assembly of heavy equipment. Anaerobic sealants remain<br />

liquid when exposed <strong>to</strong> air, but cure when the metal parts<br />

are assembled and the adhesive is confined between<br />

mating flanges. OEMs and subsuppliers have long been<br />

enjoying the technical and economic benefits of anaerobic<br />

gasketing materials, and <strong>Loctite</strong> ® 5188 takes this<br />

technology <strong>to</strong> a new level.<br />

adhesion <strong>to</strong> metal surfaces, especially <strong>to</strong> aluminium,<br />

and provides immediate low pressure sealing.<br />

Resistance of the cured product <strong>to</strong> thermal and<br />

chemical stress is excellent. It provides elongation<br />

<strong>to</strong> compensate for micro-movements resulting from<br />

vibration, pressure and temperature changes. Because<br />

<strong>Loctite</strong> ® 5188 allows flanges <strong>to</strong> come <strong>to</strong>gether with<br />

metal-<strong>to</strong>-metal contact, <strong>to</strong>lerances can be more<br />

accurately maintained, and the correct clamp load<br />

is ensured throughout the life of the assembly.<br />

<strong>Loctite</strong> ® 5188 has improved oil <strong>to</strong>lerance, allowing<br />

it <strong>to</strong> seal through slight oil contarmination. To suit<br />

Tear Down analysis<br />

improving industrial processes<br />

Rudolf Neumayer<br />

Manager of European<br />

Technical Service and<br />

Engineering, Henkel, Munich<br />

Have you ever felt the urge <strong>to</strong> take a washing machine<br />

apart <strong>to</strong> see how it works Or an oven A fridge, maybe<br />

If your answer <strong>to</strong> any of the above questions is yes, you<br />

will probably envy Rudolf Neumayer: Because that’s what<br />

he does for a living. The friendly Bavarian lights up when<br />

he starts talking about taking things apart.<br />

“Taking things apart” is not his official job description, of<br />

course. Rudolf Neumayer is Manager of European Technical<br />

Service and Engineering for Henkel in Munich. He works<br />

out of Henkel’s Innovation Centre in Munich and is part of<br />

an interdisciplinary team of specialists that is responsible<br />

for what Henkel calls the “Teardown Analysis”, also known<br />

as taking things apart.<br />

Tearing it down<br />

What is the rationale behind such an analysis, apart from<br />

the sheer joy it seems <strong>to</strong> bring <strong>to</strong> the people involved in the<br />

activity A Tear Down analysis is a form of Value Engineering,<br />

i.e. the attempt <strong>to</strong> look at each<br />

component of a<br />

finished<br />

product, <strong>to</strong> see whether the value of the product can be<br />

enhanced or the cost of manufacturing can be cut.<br />

“Value Engineering or Value Analysis was conceived in the<br />

early 1940s by Lawrence D. Miles while he was employed<br />

by General Electric, a major defense contrac<strong>to</strong>r which<br />

was facing the scarcity of strategic materials needed <strong>to</strong><br />

produce their products during World War II, according <strong>to</strong> a<br />

paper published by the International Value Society in 2007.<br />

From those humble beginnings, Value Engineering has<br />

come a long way. One of the paths the development of<br />

the method has taken is the Tear Down Analysis practiced<br />

by Neumayer and his team. “In the last 3 years, we have<br />

worked on over 60 projects with a broad range of major<br />

international companies,” explains Neumayer. Since the<br />

cus<strong>to</strong>mers enter a very confidential relationship with Henkel,<br />

giving access <strong>to</strong> manufacturing sites and construction<br />

plans, it is understandable then Neumayer guards their<br />

identities very carefully and refuses <strong>to</strong> even hint<br />

at them during the interview.<br />

Dreaming of windmills<br />

What he does talk about is in what way<br />

he and his team have achieved some quite<br />

stunning results on some of the projects: Adhesives,<br />

aka glue, are something else that Rudolf from Bavaria<br />

seems <strong>to</strong> feel passionate about. “It is a problem that in<br />

many vocational trainings, people aren’t taught enough<br />

about the possibilities that modern adhesives open up,”<br />

he says in English. Surprisingly, his English sounds a lot<br />

more polished and difficult <strong>to</strong> place <strong>than</strong> his German. The<br />

fact that he is responsible for the whole European area<br />

and speaks English most of the time seems <strong>to</strong> have taken<br />

its <strong>to</strong>ll.<br />

And what kind of machine would he like <strong>to</strong> tear down<br />

next “A windmill would be nice,” he says, with a dreamy<br />

look in his eyes…<br />

“To give you an example: For a major cus<strong>to</strong>mer (we only<br />

deal with cus<strong>to</strong>mers that do mass-production, otherwise<br />

our process wouldn’t make any sense) we managed <strong>to</strong><br />

replace a step in the production process of his washing<br />

machine by using <strong>Loctite</strong>. That way, the production has<br />

become cheaper and the cus<strong>to</strong>mer was able <strong>to</strong> fit a<br />

larger drum inside the washing machine. So, it’s good for<br />

everybody: Good for us because we have a new cus<strong>to</strong>mer<br />

for <strong>Loctite</strong>, good for the manufacturer because they raise<br />

their margin, and good for the consumer because they get<br />

a larger drum,” he explains enthusiastically and it is hard<br />

<strong>to</strong> disagree with him.<br />

And it doesn’t s<strong>to</strong>p here, at least not for Rudolf:<br />

“We have only just started, we have just scratched the<br />

surface of what’s possible,” he says and his eyes gleam.<br />

Energy – the breath<br />

of civilisation<br />

With every breath we take, according <strong>to</strong> Traditional Chinese Medicine, we receive<br />

our share of Chi, the universal energy keeping us alive. Normally we are not aware of<br />

breathing. Normally we are also not aware of the energy, equivalent <strong>to</strong> 120,000 TWh,<br />

produced and used each year around the world <strong>to</strong> keep our society alive, except<br />

when our cities stay dark, oil becomes <strong>to</strong>o expensive or there is no gas for heating.<br />

Watt – the man who brought the dawn of endless<br />

opportunity<br />

In 1776 James Watt ins<strong>tall</strong>ed the first industrial standard<br />

steam engine. This was the dawn of our modern,<br />

technology-driven society that soon became inseparably<br />

linked <strong>to</strong> and dependent upon a continuous and growing<br />

supply of energy. From these very first days, energy<br />

production and transport became a global network, as<br />

unobtrusive as it was reliable, always available and ready<br />

<strong>to</strong> work. The impact energy has on daily life, the way<br />

energy characterises society becomes apparent when<br />

malfunctions occur; only when cities remain dark, or when<br />

oil, gasoline or natural gas run short or become unavailable<br />

do we fully understand our lifestyle’s dependence on<br />

energy. Without an energy supply there is no mobility, no<br />

media, no information technology, no commodities nor a<br />

food supply; medical care and hygiene is reduced instantly,<br />

and in the worst-case-scenario there is iciness.<br />

Sources and uses of energy<br />

For more <strong>than</strong> a hundred years, the world’s energy<br />

consumption has increased rapidly. Today the demand<br />

for energy is nearly twenty times greater <strong>than</strong> in 1900<br />

and twice as big as in 1970. Of the energy consumed<br />

globally, 58 % is produced by oil and coal, 24 % by natural<br />

gas, and 18 % by biomass, renewable energy and a<strong>to</strong>mic<br />

power plants. In the distant past, coal was a less-<strong>than</strong>ideal<br />

solution for those who could not afford wood and<br />

had <strong>to</strong> use these putrid, smoking s<strong>to</strong>nes for cooking and<br />

heating. But the growing demand for metal, and James<br />

Watts’ steam-engine paved the way <strong>to</strong> a coal-driven era.<br />

Soon large cities like London, Bos<strong>to</strong>n, New York and Berlin<br />

were illuminated by coal-produced <strong>to</strong>wn gas. From 1800 <strong>to</strong><br />

1850, coal consumption grew from 10 million <strong>to</strong>ns (mt) <strong>to</strong><br />

76 mt. In 1900, 760 mt of coal were used in a single year.<br />

In those days, coal covered 90 % of global fuel needs.<br />

The rise of industrial nations would not have been<br />

possible without the combined power of coal and the<br />

steam engine. Even <strong>to</strong>day, coal production is still rising.<br />

Due <strong>to</strong> the increasing demand for energy, especially in<br />

China, coal production was at an all time high of 5.4 bn<br />

<strong>to</strong>ns in 2007 – equivalent <strong>to</strong> a 1.4 kilometre cubic block<br />

of coal, and an increase of more <strong>than</strong> 30% within only<br />

five years.<br />

The rise in demand for crude oil started with an ingenious<br />

marketing campaign. To sell more petroleum, J.D.<br />

Rockefeller gave away free oil lamps. So people bought<br />

his oil instead of expensive and rare whale oil. Some years<br />

later, refined oil played a key role in developing the newly<br />

invented mo<strong>to</strong>rcar, and oil became the basis of mobility.<br />

From then onwards, a global distribution network was<br />

introduced that included drilling rigs, pipelines, crude oil<br />

vessels, refineries and gas stations. Since 1960, crude<br />

oil has been the most important fossil fuel, covering one<br />

third of world energy consumption. A 60% share of oil<br />

production is used for traffic and transport. In 2008 the<br />

average daily production and use of crude oil was 85 million<br />

barrels (one barrel =<strong>15</strong>9 litres) a day or 31 bn barrels a year,<br />

which is 4933 bn litres or 4.9 cubic kilometres – this would<br />

make a cube with sides 1,68 kilometres long.<br />

Natural gas has been available since the beginning of oil<br />

production, was mainly considered as an unimportant<br />

and dangerous by-product. In the 1980s, natural gas<br />

became established as a basic energy resource for<br />

industrial production, the production of electricity, and for<br />

households. This economic breakthrough was founded<br />

on the convenience, warmth and cosiness that natural<br />

gas offered as a replacement for coal-produced <strong>to</strong>wn<br />

gas. Today, natural gas is still a major fuel for generating<br />

electricity and for residential domestic use. The <strong>to</strong>tal<br />

worldwide amount of natural gas extracted in 2007 was<br />

2940 bn m3 – this time enough <strong>to</strong> make a cube with 14<br />

kilometre-long sides.<br />

<strong>How</strong>ever, progress was followed by adverse effects. In<br />

<strong>to</strong>tal, burning oil, coal and gas produces 26.100 bn <strong>to</strong>ns<br />

(13.300 bn cubic kilometres) of carbon dioxide a year –<br />

imagine a cube with sides 23.7 kilometres long. This is the<br />

problem of growing energy consumption – nature cannot<br />

recycle all the man-made CO2 and so the atmosphere<br />

is becoming overloaded with this gas. In addition, fossil<br />

resources are limited but in the future there will be a vital<br />

need for these precious raw materials – for synthetics as<br />

well as for life-saving pharmaceuticals and hundreds of<br />

other products derived from crude oil. Dependency on<br />

fossil resources has also become an economic and a<br />

political source of crisis. The Cold War as well as power<br />

games with and between main oil-producing countries<br />

has led <strong>to</strong> economic imbalances. Long-distance transport<br />

routes, volatile prices, geopolitical instability, trouble spots<br />

and economic dependency on a few energy providing<br />

countries are causing a worldwide re-evaluation of energy<br />

systems.<br />

The breath of the sun – light, heat, wind<br />

In contrast <strong>to</strong> fossil energy production, a<strong>to</strong>mic energy,<br />

hydro power, biomass and renewable energy represent<br />

only one fifth of world energy production. Nevertheless, the<br />

hope for an enduring and stable energy supply depends<br />

on renewable resources such as the wind, sun, biomass<br />

and water. The reason is obvious; in only three hours the<br />

sun sends as much energy as the whole world needs in<br />

a year.<br />

Therefore only 3 % of the Sahara‘s land area would be<br />

enough <strong>to</strong> cover the world’s usage of electricity. Only a<br />

fraction of available solar energy is used now even though<br />

solar power capacity increased from 2 Petajoules (Pj) <strong>to</strong> 13<br />

Pj in the period from 2004 <strong>to</strong> 2008. In 2008, wind energy<br />

plants, mainly in Germany, the USA and Spain, produced<br />

94.000 MW of electricity. A huge potential remains<br />

un<strong>to</strong>uched. The overall potential of renewable energy<br />

also depends on technical as well as geographical and<br />

economic conditions. Only a fraction of the solar energy we<br />

Less is more – power efficiency<br />

The largest power plant does not produce any energy;<br />

it is designed <strong>to</strong> save energy by intelligent and efficient<br />

usage. On the road from power production <strong>to</strong> the enduser<br />

there are often losses of up <strong>to</strong> 90% measured against<br />

energy input. There are losses within the power-plants,<br />

losses of transmission and distribution, and losses in power<br />

conversion, for example:<br />

• A bulb converts only 3 % of electric energy in<strong>to</strong> visible<br />

light<br />

• Only 13 % of gasoline energy reaches a car’s wheels.<br />

• 80 % of heating and climating losses in buildings could<br />

be avoided by efficient thermal insulation.<br />

The reduction of losses is multiplied as the energy travels<br />

back <strong>to</strong> power plants. If losses cause a reduction of energy<br />

from say 100 produced units <strong>to</strong> 10 units output, an increase<br />

of efficiency from 1 unit on the output side will save 10 units<br />

on the input side. Therefore energy efficiency is the most<br />

promising power source of the future.<br />

The Evolution of Technology<br />

For more <strong>than</strong> <strong>15</strong>0 years the increasing availability of energy<br />

has improved access <strong>to</strong> resources and the production and<br />

supply of food. It has enabled unprecedented mobility,<br />

information availability, communication, and the usage<br />

of sophisticated technical devices. New technologies<br />

evolve whenever existing applications turn out <strong>to</strong> be<br />

<strong>to</strong>o costly <strong>to</strong> resolve new problems. Old technologies<br />

will either be optimised or gradually substituted by their<br />

successors, unless the problem itself is altered or changed<br />

by new perspectives and solutions. It is obvious that<br />

an environmental and socio-economic driven change<br />

in energy-technology lies ahead. It is also obvious that<br />

essential technologies already exist or are in development,<br />

ready <strong>to</strong> compete <strong>to</strong> provide useful and practical solutions.<br />

Even now there are numerous inventions and innovations,<br />

such as new technologies <strong>to</strong> produce and save energy or<br />

efficient production solutions <strong>to</strong> preserve natural resources.<br />

New materials, components and drives are steadily<br />

reducing the energy demands of industry and transport.<br />

New concepts of mobility will evolve <strong>to</strong> a essential criteria.<br />

The final goal should be, as Traditional Chinese Medicine<br />

advises, <strong>to</strong> keep the flow of energy alive – with every breath<br />

we take.<br />

Insane pieces of engineering<br />

If you are the kind of person that doesn‘t like sciencefiction,<br />

because you are interested in reality, Allmannsweier<br />

in Baden-Württemberg is the place for you.<br />

Allmannsweier in Baden-Württemberg is one of the more<br />

pleasant regions of Germany, famous for its good food and<br />

the friendly locals. It‘s also the home of Herrenknecht, the<br />

world‘s leading manufacturer of tunnel boring machines.<br />

And it‘s those machines which dwarf the imagination of<br />

your average Hollywood screen writer. It’s not surprising<br />

that the company and its charismatic founder, Dr Martin<br />

Herrenknecht has attracted a lot of attention from the<br />

global media lately.<br />

“An insane piece of engineering” is how the American<br />

Discovery Channel describes the Herrenknecht machine<br />

that drilled a 5.4 and a 3.9 kilometer tunnel in Kuala Lumpur<br />

in 2006.<br />

The defining project of Herrenknecht‘s career and one of<br />

the greatest public works of any kind is the Gotthard Base<br />

Tunnel. The tunnel, which has been under construction<br />

since 2002, will run from the village of Erstfeld, in central<br />

Switzerland, <strong>to</strong> Bodio, in the southeast, a distance of more<br />

<strong>than</strong> 57 kilometers. When completed, in 2017, it will be<br />

the longest traffic tunnel in the world; it is also one of the<br />

most geologically challenging, The Gotthard crosses nine<br />

geological zones. It cuts through granite and quartz, along<br />

fault lines and beneath a sugar like layer of dolomitic marble<br />

– a challenge <strong>to</strong> anything going through it.<br />

No <strong>rock</strong> <strong>to</strong>o hard, no mountain <strong>to</strong>o high:<br />

<strong>Loctite</strong> ® and Herrenknecht<br />

Herrenknecht has been growing ever since its foundation<br />

in the 70s. It now employs around 3000 people worldwide<br />

and sales reach 1 billion Euro for the first time in 2008.<br />

This impressive success s<strong>to</strong>ry is partly due <strong>to</strong> the fact<br />

that Herrenknecht <strong>to</strong>ok advantage of the opportunities<br />

offered by globalisation. China is one of the countries which<br />

Herrenknecht focused on early and in 2008 they were able<br />

<strong>to</strong> celebrate the delivery of the 100th machine <strong>to</strong> the powerhouse<br />

of the world economy.<br />

Wherever one of the machines operate, Malaysia, China,<br />

Switzerland or Brazil, Henkel‘s <strong>Loctite</strong> ® products always<br />

play an important role during the construction of those<br />

insane pieces of engineering. <strong>Loctite</strong> ® threadlocker 243 is<br />

used <strong>to</strong> lock all the screws in the machine, which has <strong>to</strong><br />

withstand enormous pressure while it eats its way through<br />

the <strong>rock</strong>.<br />

Another application which makes good use of the<br />

reliability that <strong>Loctite</strong> ® stands for, is the machine’s rotating<br />

cutting head. The cutting head's power unit relies on a<br />

variable number of single engines. The superstructural<br />

part's flange ring and main bearing as well as transmission<br />

case and main bearing are cemented repeatedly in a<br />

laminary fashion, using <strong>Loctite</strong> ® 586. This process allows<br />

<strong>to</strong> transmit more <strong>than</strong> twice the turning movement<br />

that would be possible otherwise. The cementing with<br />

<strong>Loctite</strong> ® enhances the reliability and allows the power<br />

unit <strong>to</strong> withstand the forces that can come <strong>to</strong> bear on it<br />

underneath the earth.<br />

<strong>Loctite</strong> ® Sales Engineers are also involved in the planning<br />

process of the machines, liaising with the various<br />

Herrenknecht departments in order <strong>to</strong> meet the cus<strong>to</strong>mer’s<br />

construction needs as early as possible. Henkel and<br />

<strong>Loctite</strong> ® are ideal partner for Herrenknecht’s tunnel-boring<br />

machines, which never quite know what kind of <strong>rock</strong> they<br />

will have <strong>to</strong> taste next. <strong>Loctite</strong>’s Rapid Response Process<br />

(see Product Development Article), allows us <strong>to</strong><br />

Interview<br />

Christian Draeger, Traffic Tunnelling Sales<br />

Department, Herrenknecht AG<br />

Wolfram Lais, Head of Subassembly,<br />

Herrenknecht AG<br />

You're using <strong>Loctite</strong> ® products for a wide variety<br />

of applications in the manufacturing process of<br />

your equipment. What <strong>Loctite</strong> ® products do you<br />

use in the manufacture of tunnel boring machines<br />

Mr. Lais: In our department we mainly use <strong>Loctite</strong> ® 586<br />

for bonding flanges and 577 for thread sealing, 243 for<br />

threadlocking and <strong>Loctite</strong> ® 7070 as a cleaner.<br />

Where do you use <strong>Loctite</strong> ® adhesives on your<br />

machines Mr. Lais: We use <strong>Loctite</strong> ® mainly on the<br />

cutting wheel drive. We apply product 586, <strong>to</strong> increase<br />

friction.<br />

<strong>How</strong> does such a tunnel boring machine get from this<br />

production facility <strong>to</strong> its final destination <br />

Mr. Draeger: The tunnel boring machine is fully assembled<br />

right here in the fac<strong>to</strong>ry. But, <strong>to</strong> move the machine <strong>to</strong> the<br />

construction site, it must be disassembled again.<br />

That's why the machine is completely modular in design,<br />

and modules are assembled with bolts. We will disassemble<br />

these bolted joints <strong>to</strong> get accurate structures which we<br />

can transport <strong>to</strong> the construction site. Once they have<br />

arrived at the construction site, these structures are then<br />

re-assembled, tightened with bolts or welded.<br />

In general, what parts of a machine are most severely<br />

stressed during operation of the equipment Mr.<br />

Draeger: The cutting wheel and the main drive are<br />

subjected <strong>to</strong> very high loads. Just imagine that the cutting<br />

wheel is moving through the ground, encountering a variety<br />

of soil types and loading conditions. There may be hard<br />

<strong>rock</strong> or loose <strong>rock</strong>. In the case of hard <strong>rock</strong> it's mainly the<br />

pressure and the force <strong>to</strong> be transmitted by the<br />

cutting wheel when it's carving away the <strong>rock</strong>.<br />

With loose <strong>rock</strong>, it's mainly the <strong>to</strong>rques, the<br />

rotating or twisting forces that act there and<br />

cause very high stresses.<br />
