In what kind of extreme conditions can

your products be used? What about explo-

sion protection?

Our products are more robust than any

comparable competitor. A device must

pass strict test runs before it is even

launched on the market. We drop it from

a metre high onto a concrete floor, for ex-

ample. Next we smash a 1 kg steel ball onto

the display from 20 centimetres. We then

vary the ambient temperature between -20

and +45 °C.

Have you ever been in a dangerous situa-

tion yourself? Maybe you experimented

with explosive substances as a boy?

(Laughs) Don’t forget, in our business we

aim to prevent explosions, not cause them.

But I must admit, when I was younger I was

often in my father’s workshop and had

plenty of dangerous projects on the go, but

the less said about those the better. Let’s just

say I’m happy that I survived.

Putting these dangerous antics aside, what

helps you personally to win over a customer?

Well, I’m Norwegian for a start! Seriously,

that actually helps. In contrast to the USA,

where drilling mostly happens on shore, oil

and gas in Norway are extracted way out at

sea. This forces us to think innovatively.

Aside from that, I also bring my specialist

knowledge as an electrical and mechanical


Mr Rokseth, BARTEC PIXAVI is the

world’s leading provider of mobile commu-

nication devices for explosive areas. How

have you achieved this?

We produce the mobile devices from

scratch ourselves, using our own technol-

ogy. Other competitors rely on outsourc-

ing, for example in the development of cir-

cuit boards and software. By contrast, we

do everything ourselves with a carefully

selected team.

You had to rely on yourself at the start. In

1999, you developed a wireless audio,

video and data communication system

based on your master’s thesis. What was

your motivation?

I realised that although there was already

high-speed internet in the refineries, there

were no wireless solutions for communi-

cation on oil drilling platforms. I wanted

to change that. In 1998, I had to apply for

special permission to import the first Wi-

Fi access point into Norway. The next job

was to


down the hardware*.

How did you consider things from an eco-

nomic standpoint?

After I had analysed the situation where re-

pairs are required on a drilling platform, I

asked myself: why does the operation al-

ways need to be stopped until the experts

arrive? I wanted to reduce the need for trav-

el whilst ensuring that the necessary expert

knowledge was always available, so that

problems could be solved efficiently in real


What exactly can “go wrong” on a drilling

platform and how does your technology


A typical example is when a compressor fails.

Previously, the drilling platform would

have to shut down for a good two days be-

fore the experts were on site. Now the cus-

tomer can solve this kind of problem via

video with the help of BARTEC PIXAVI.

The downtime is virtually eliminated, so

the customer effectively gains two days.

Impressive. How much training does it re-

quire to operate?

Can you use a smartphone? If so, then you

can operate our products.

That is how you presented yourself to the

oil companies. How did they react?

Right from the start, my ideas were accept-

ed with great enthusiasm by the oil and gas

industry. There was, however, a dispute

with the unions. But they soon came to the

conclusion that no jobs would be put at risk.

So the project got off the ground and the oil

and gas industry is still a key part of our


What is your detailed approach today for

solving customer problems?

As a basis, we require either colleagues with

a mobile phone or a local Wi-Fi network.

Nowadays that’s no problem – 90% of drill-

ing platforms have Wi-Fi. Once that is es-

tablished, we can connect the BARTEC

PIXAVI devices, such as our ex-certified

wireless video conferencing system Xcaster

EX5000 The service personnel on the drill-

ing platform receive support from on-shore

experts via real-time video and audio link.

This helps to quickly find and implement

the best and safest solution strategy for the

case at hand.

You always put particular emphasis on HD.

Is HD really required for every application?

To be honest, HD has become the standard

now. So offering it is not a luxury, but a


Let’s finish by looking forward. What ex-

citing “necessities” have you got planned

for the future?

Our focus is currently on launching our

new smartphone and video communication

technology, which will be released this year.

These products will revolutionise commu-

nication in certain sectors.

The temperature on the sea
bed is constant at 4 °C. This
temperature, combined with
the often long transport dis-
tances, poses serious chal-
lenges to

crude oil extraction


As soon as the temperature in
the pipeline falls below 80 °C,
the flow of oil begins to slow.
To counter this risk, the pipe-
lines are fitted with an insu-
lating lining, but are now also
being protected with integrated
trace heating.

Pipe-in-pipe technology



Heating circuit length: up to 20 km

Oil well temperature: > 100 °C

Ambient temperature: 4 °C


At temperatures below 80 °C, crude oil

changes in a way that can lead to problems.

The paraffin in the oil compresses to form

wax. In addition, the long-chained hydrate

molecules, compounds containing water,

turn into knotted, fluff-like structures. The

situation becomes especially critical when

the wax and hydrates meet and become a

sticky mass. The flow of oil gets bogged

down, resulting in expensive downtimes for

the extracting company.

The oil bubbling up from a freshly tapped

well will initially be between 100 °C and

130 °C. But even in well-insulated pipelines,

the temperature will fall significantly soon-

er or later.


with heating

The solution is the pipe-in-pipe process

with electrical trace heating, also known as

ETH-PIP. In this system, the pipeline car-

rying the oil is covered in heating strips that

are supplied with electricity via feed-in

points. This keeps the oil in the pipeline at

a sufficiently high temperature, preventing

it from clogging. From an economic stand-

point, the system helps keep the process

flowing. Additional protection against low-

er temperatures is provided by two layers

of insulation around the heating strips

made from highly insulating polymers.

This forms a second pipe surrounding the

pipeline that actually transports the oil –

this is where the name “pipe-in-pipe” comes

The pipelines are first wrapped before being

laid. A single spool can measure up to 80

metres across and have up to eight kilo-

metres of pipeline. The tensile force and the

curvature puts great stress upon the heating

tapes, meaning that the heating cables have

to be robustly designed. A maximum of

four heating tapes arranged in a spiral

around the inner pipe also help to reduce

the high tensile and bending forces.


are the key

This considerable increase in efficiency in

the pipe-in-pipe procedure is made possible

by new technology. A special semiconduc-

tor layer surrounding the copper wire pro-

tects against the corona effect. This allows

a voltage of up to 5,000 volts to be applied.

With just a single feed-in point, it is possible

to create heating circuits up to 20 kilo-

metres in length. It becomes clear how

much money the extracting company can

save when you think about the costs for a

single feed-in point.

“Deep Sea Star”, the product developed by

BARTEC in cooperation with big-name

partners, has been available since 2013.

Going deeper

Whilst stocks just below sea level have been

almost fully exploited, there are massive re-

serves hidden below 800 metres. Heated pipe-

in-pipe systems are needed to retrieve these.

There is also price pressure on the extractors.

The fracking process, in which oil is won from

the rock using pressure and chemicals, is be-

coming increasingly common in the USA and

allows new oil reserves to be accessed more

economically. Manufacturing costs need to

be kept to a minimum in order to stay com-

petitive on the global market. The newly de-

veloped and highly efficient pipe-in-pipe pro-

cedure could help make crude oil extraction

more cost-effective.

Oil belongs in the pipeline, not in the sea. The

control systems that ensure this are highly

complex. BARTEC has now supplied flexible and

customer-specific switching cabinets for just

this  purpose.

marine ecosystem, but also to the

image of the pumping company.

Keeping crude oil safely in the pipeline at

all times is therefore an absolute must.

This is known in the industry as “blowout


The technology that guarantees this is

highly complex and costly. After all, it has

to operate under extreme conditions. As

soon as a hole is drilled in a deep-sea oil

well, the oil comes shooting out at high

pressure. In addition, currents on the sea

bed are often rough.

Blowout prevention under these kinds of

conditions requires more than just solid

seals. To counter the oil pressure, heavy

units around the drill head press against

the sea bed. The electronics of this appara-

tus are controlled by special switching cab-

inets. BARTEC recently delivered seven of

these cabinets for an oil platform run by

National Oilwell Varco (NOV), one of the

world’s leading suppliers of equipment to

the oil and gas sector.

“Every application case is different,” explains

Wolfgang Stadie, Vice President Western

Europe at BARTEC. “A well in the North

Sea will present completely different chal-

lenges to one in the South Pacific.” The drill-

ing platform in question is found in the mid-

dle of the North Sea off the coast of Scotland,

where it is battered every day by raw winds

and powerful waves. The front plate of the


cabinet had to be painstakingly engraved so

as to ensure that it can still be read well into

the future. This special requirement and

many others were made easier thanks to

the close cooperation between NOV and

BARTEC technical consultant Markus Etzel.

The systems were produced at BARTEC’s

facility in Bad Mergentheim. The empty

switching cabinets were delivered by NOV

and then filled according to the customer’s

precise specifications.

On time
despite changes

Particularly challenging were the requests

for changes, which often came while test

runs were still ongoing. “That is to be ex-

pected during the course of a project,” ex-

plains power engineer Etzel, speaking from

experience. “The most important thing is

to be able to react flexibly, so that everything

still works.”

This flexibility allowed the customised off-

shore application to be delivered in half the

scheduled time. “The team at BARTEC

made a decisive contribution to the project

being completed so quickly and the panels

being delivered five weeks ahead of sched-

ule,” says John Warden, Electrical Projects

UK Field Engineering at NOV Rig Solutions.

Each of the switching cabinets will soon

control ten units, doing their bit to keep

Scotland’s waters clean.

eep drilling needs to be precise

and focused. In the control cabins

of drilling platforms, every centi-

metre counts. The enclosures for conven-

tional controls are large and therefore not

ideal. By contrast, the explosion-protected

remote I/O ANTARES from BARTEC can

be fitted into much smaller spaces.

High automation,

high safety

The company Bauer Deep Drilling special-

ises in highly automated, high-tech rigs.

“We began as a specialist for deep drilling

at 100 metres. The drilling is the same, it’s

just done a little bit deeper,” smiles Lothar

Schirmel, Head of Design and Develop-

ment Electronics Deep Drilling. “The ex-

tracting companies also need to dig deep-

er into their pockets. A standard drilling

tool costs between 2,000 and 3,000 euros,

the deep drilling platform around 20 mil-

lion euros. “Suffice to say, this is not a mi-

nor investment. The customer wants to see

that the system works. You can’t sell this

kind of system just on paper,” explains

Schirmel. The Bavarian company therefore

constructed their newest model above a

1,000 metre borehole for demonstration

purposes. “This allows us to simulate the

installation,” explains Franz X. Both, Pro-

ject Manager at Bauer Deep Drilling.

The high degree of automation gives the

company more security and allows human

resources to be better deployed. Having

fewer people in dangerous areas also re-

sults in a lower risk of injury. This is an

important point, as in the event of an in-

jury, the facility has to be stopped com-

pletely. A day’s production is quickly lost.

This costs a good 25,000 euros.

Compact, direct, flexible

Until recently, Bauer Deep Drilling bought

the finished control cabins for the systems

from competitors. “We then decided that

we wanted to build them ourselves in the

future. We could have done it exactly the

same way,” says Schirmel. In the previous

models, a standard control unit was in-

stalled in a flameproof enclosure. This

meant that explosion protection was no

longer ensured when the cover had to be

opened in the event of a malfunction. The

certified ANTARES, by contrast, can be

installed directly in the Ex area.

Thanks to its large reserve capacities, the

system offers efficient and compact I/O

configurations. A single rail control unit

(RCU) can supply up to 32 multi-channel

modules, resulting in a very high number

of input/output channels.

Furthermore, ANTARES provides the

benefit of a flexible system certification.

Previously, remote I/O systems had to be

clearly planned in advance and installed

in certified Ex e enclosures with rigid ap-

proval. Now, every electrical planning op-

eration can plan, alter and expand its sys-

tem freely.

biggest consumers of natural gas. All the

The product, called HYGROPHIL HCDT,

is suitable for use in explosive areas and has

become standard equipment for natural gas


The two measurements are covered by one

device, which both lowers costs and in-

creases efficiency. Together with a sample

preparation and optical sensors, the

HYGROPHIL HCDT not only minimises

the recalibration workload due to the vir-

tually drift-free measurement, but also re-

moves the need for intensive cleaning work,

as the contaminations carried in the gas do

not affect the measurement. The hydrocar-

bon dew point sensor’s very low detection

limit allows it to detect the build-

up of condensation early.

The instruments therefore make

an active contribution to quality

assurance. After all, only when

the measurements are consist-

ently precise can the status in the

gas grid be correctly checked and

recorded and the quality of the

gas proven and maintained at a

high level.

As a gas transporter, Snam Rete Gas must

ensure three things every day: gas quality,

facility protection and cost reduction.

BARTEC helps to achieve these goals as ef-

ficiently as possible, meaning Italian gas

consumers can rest easy as they sip their es-

presso, brewed using electricity from clean-

ly transported natural gas. Tutto bene.


This has been the task for Snam Rete Gas,

Italy’s largest gas transporter, for over 70

years. The pipeline network stretches for

32,000 kilometres up and down the Italian

“boot”. The gas, from Russia, northern Eu-

rope and northern Africa, is conveyed by

Snam Rete Gas to local distribution net-

works, industrial bulk buyers and power

stations. Snam Rete Gas’ distribution centre

in Milan works around the clock to ensure

that the gas is available everywhere at all

times in the required quantity and quality.

The team focuses particularly on quality

factors such as the dew point.

This is the temperature at which dew forms.

To explain: water vapour precip-

itates as mist or dew droplets

when the ambient temperature is

equal to or below the dew point.

The lower the water dew point,

the smaller the quantity of water

vapour in the gas. The lower the

hydrocarbon dew point, the

smaller the quantity of heavy hy-

drocarbons. Both must be avail-

able in order to achieve high gas quality. In

addition, high dew point values are a po-

tential risk factor for every natural gas fa-

cility. This is why they require constant

monitoring by Snam Rete Gas. This is

where BARTEC comes in.

Snam Rete Gas uses a combined dew point

measuring device for water and hydrocar-

bons from BARTEC BENKE.







The technology behind


The sensor contains a miniature chilled

mirror. The special surface is systemati-

cally heated and cooled. The reflectivity,

which changes as the result of the build-

up of condensation, is measured subject

to the temperature. This results in a high

level of precision of +/- 0.5 °C, making it

a highly reliable indicator for natural gas


Innovative solutions


For less critical applications for example,

the new HYGROPHIL F Basic presents a

compact, robust and cost-effective solu-

tion for measuring the water dew point.

It can be installed directly at the point of

use, removing the need for long cables

between the sensor and the electronics.

The future plans for Italy’s

natural gas grid

The focus will be on customer-specific

solutions, particularly in the HCDT tech-

nology of HYGROPHIL. The product will

continue to be developed further so that

it can be used for a range of different gas

compositions. BARTEC’s aim here is to

provide products tailored for the Italian

gas market.

How can you use whisky to build good relationships?

What has BARTEC got planned for the north of

Great Britain? And where does a Scot go when he

wants to fill up? Robert Lee, Area Sales Manager for

Scotland at BARTEC UK, tells all.

Interview: Markus Lipp /// Photos: Neil Gordon




background image

o, he doesn’t own a kilt. “I don’t

even drink whisky,” laughs Rob-

ert Lee. He is still a proud Scot,

but his pride comes less from appearances

and more from inner values. Modesty, ac-

cording to Lee, is a very Scottish virtue.

Those wanting to get ahead here need to

be open, honest and down-to-earth.

Lee therefore really doesn’t need any of the

high-percentage “water of life” to maintain

spirited customer relations. His honest

manner in dealing with customers is much

more important. “Honesty is everything,”

says Lee, “You have to keep your custom-

ers up to date regularly and give them clear

information.” And he should know, after

over 20 years of experience in sales.

This combination of honesty and experi-

ence has provided him with a steady sup-

ply of success stories to tell. One example

is the cooperation with drinks giant Dia-

geo, who had the remote I/O system

ANTARES installed at their whiskey dis-

tilleries by the team from BARTEC UK.

Previously, Diageo was using a competi-

tor’s system and were won over by the new

technology, greater flexibility and time

saving provided by the BARTEC solution.

Scotland, Robert Lee’s homeland, is a land

of hidden treasures. It may be a small

country, slightly larger than Bavaria at

around 78,000 km², but it is home to some

of the world’s biggest oil companies like

BP and Shell. From his base in Aberdeen,

Lee supplies these customers with switch-

ing cabinets and automation technology,

for example. Another area under his man-


agement, between Glasgow and Edinburgh,

is home to a number of petrol pump man-

ufacturers. Then there is the north with its

whisky industry.

Major brands like Johnny Walker or Chivas

are supplied by BARTEC UK with ANTARES

or mobile computers. BARTEC is therefore

doing its bit to ensure the quality of the spir-

its. “I’ll have you know that a good whisky

must be stored for at least three years before

it can be sent to retail,” explains Lee. “All the

important information is stored in a bar code

on the bottle.” This code is read by an MC 92,

even in the adverse conditions of a whisky

cellar. It’s no surprise then that the mobile

computers are currently highly sought after

by Lee’s major oil and gas customers, in

addition to products from BARTEC

TECHNOR, based in Stavanger in Norway.

But Lee is looking beyond short-term trends.

He summarises his future goal in one sen-

tence, which coming from such an other-

wise modest and down-to-earth person like

Lee makes one stand up and take notice: “I

want to make BARTEC the first choice for

explosion protection equipment.” In his per-

sonal life, Lee has long made his first choice:

the 48-year-old has celebrated his silver

wedding anniversary and the children are

grown up.

In his spare time, Lee enjoys playing golf. A

sport that has its roots in his homeland.

When he’s teeing off, he focuses on nothing

else – just himself, his concentration on the

ball and the beautiful wide landscape

around him. That’s one Scottish stereotype

Robert Lee does fulfil.

Supporting young

“The best ideas are the ones

that at first seem absurd.”

In 2002, the invention competition
“Creative minds” was founded to
promote clever ideas. Five of the school
pupils or groups of pupils who made
it to the next round in January are getting
help from BARTEC to make their
ideas reality.

t may be warm now, but come the win-

ter it will snow again – and one person

will be well prepared. Moritz Brunner

has come up with a very special type of

snow shovel. The 12-year-old noticed that

when clearing snow, one always had to go

round the yard or driveway twice: once to

shovel the snow and once to spread salt. He

started work designing a snow shovel that

can do both at the same time. BARTEC ex-

perts Stefan Beckett and Wilhelm Ruck are

helping him build a prototype. “I never

thought I would get to the final of the com-

petition with my idea,” said Moritz, still as-

tonished, at his first meeting with the spe-

cialists from BARTEC. That is exactly what

the competition aims to do – give young

people confidence in their ideas. But also

support the inventive spirit and the urge

of curiosity, discover new talents, inspire

girls for technology and open the doors

to those businesses who need precisely

this innovative spirit and growth catalyst.

How do ideas

become reality?

Moritz Brunner is one of the school pupils

being supported by experts throughout the

entire realisation process to develop a func-

tioning model based on their design. Even

the best ideas are useless unless they have

the chance to become reality. Using the

sketches he made himself, Moritz was able

to present his project to BARTEC, whose

experts then suggested ways to perfect it. “I

had a good feeling about it and the experts

from BARTEC took me and my idea seri-

ously,” he explains. The group will meet reg-

ularly and work together on the snow shov-

el until the members of the jury pick the


The competition has been met with a good

response. Almost 300 ideas are submitted

in every round, of which around 80 are re-

alised. The competition was started over a

decade ago and has been supported since

2005 by the foundation “Young Creative

Minds”. Over the years, more companies

and regions joined in and gave their support

to the competition. This has led to a creative

network connecting industry, schools and

local authorities in the region. Some inven-

tions have even had trademark protection

applications submitted to the German Pat-

ent and Trade Mark Office.


The excitement continues for the participants,

as they will soon present their ideas and pro-

totypes to the jury. The best projects will be

honoured in the following prize ceremony.

Don’t panic. Modern petrol stations are fit-

ted with a range of equipment to protect

against the risk of explosion. Even their

open construction reduces the risk. In ad-

dition, modern filling stations siphon off

the fuel fumes and feed them back into the

system. One explosion protection invention

that has long been a standard feature of fill-

ing stations is actually an early BARTEC

product. A microswitch, the size of a match-

box, fitted directly into the pump. As soon

as you take the nozzle from the holder, you

hear the switch click and the filling process

starts. The mechanical switch’s pressurised

enclosure prevents sparks escaping and

causing an explosion. In 1975, the invention

of the pressurised enclosure with a plastic

casing by the company founder was the first

milestone for BARTEC.

Did you know that petrol on its own is bare-

ly flammable? Only when mixed with air

can it be deadly. All it takes is a small

amount of petrol vapour and a spark – such

as that from burning cigarette ashes – and

BOOM! That is why smoking is strictly for-

bidden at the pump.



When you’re stood at the pump filling up

your tank, it could be a bad idea to quick-

ly nip back into your car. The friction on

the seat cushions can create an electrostat-

ic charge on your body. If you go to grab

the nozzle again, the sparks can jump over

to the fuel. This can also happen, by the

way, if the tank filler neck is defective or if

you are using poor-quality tyres.

thE mObILE PhONE –


Fortunately, getting a call from your mum

while you’re busy filling up is not life threat-

ening. In order for the electromagnetic field

of a mobile phone to be able to cause an

explosion, the antenna must deliver at least

six watts. The current maximum is two. The

phone could only send sparks flying in the-

ory if it fell on the floor and the battery

sprang out.
