Introduction
Challenges and
good innovations
Water is the world’s most important
resource for all life on the planet? As we
know, drinking oil is not an option!
However, the Norwegian oil adventure
has resulted in more than creating the
world’s richest country. It has resulted in
us possessing valuable competence that
can be scaled up and distributed in various technical areas. This involves prospecting, shipping, storing and processing
of liquid. Water is the world’s most
important liquid and Norwegians are traditionally concerned about pipe systems
that ensure safe handling of water. The
pipes are crucial in the transport of water to and from the consumer, but both
have limited lifespan and requires renovation. Oliner System is a Norwegian
innovation with a large international area
of application: Oliner System gives old
sewer pipes a new lifespan.
No one owns the water resource
- we all borrow it from the next generation. We all must accept this responsibility. The water mains in buildings
represent a considerable value, but
they also pose an enormous risk to
the environment or a private economy
if the pipes are leaking. Leaking pipes
in buildings have directly leaded to
economic consequences for the owner.
Insurance companies, homeowners and
Carl Christian Sibbern
CEO, Olimb Group
administrators capitalize on focusing on
entire pipe systems instead of repairing
the individual leakages. Pipe renovation
of the whole pipe system gives a win-win
situation. More people open their eyes to
Oliner System’s non-destructive methods. We were the first in the world with a
certified system (SINTEF) for a complete
pipe network certification, and it is
satisfying that this strict quality standard
is being used more where we certify our
products (IATMO, NSF, SP, DiBt, etc.)
A focus on water
The largest water resources are found
under the world’s oceans, or in deserts
such the Sahara. Large drinking water
resources, for example, in Libya, were
destroyed because drilling through
drinking water reservoirs in order to
access the oil underneath. OMAG in
this respect shows that the water and
waste water industry is a market full of
opportunities. There are a number of
innovations, well-known methods and
established products available in the
market. However for the segment inside
buildings, there is a crying need for
solutions that do not involve demolition,
moving, etc. Products of high quality
with a long lifespan are in demand
among both installers and consumers.
Leaks inside buildings have such a great
consequence that products and methods
must provide maximum predictability
and minimal risk. The long-term capacity of the finished product is directly
connected with the quality of products,
training and ability to perform. Olimb
established the world’s first factory for
production of so-called “liners” for use
in pipe renovation. This was in 1977, and
since then we have installed more than
a million metres onshore and in offshore
(offshore since 1992). We are very proud
of our subsidiary, Oliner System, which
since 2007 has expanded this competence further into buildings using good
methods of logistics, process management and installations. Oliner System is
expanding through new partners where
our tailored products and methods are
employed. It is motivating to meet wonderful new ambassadors with the same
attitude towards quality and delivery. It
will be interesting to follow the further
development in the Netherlands and
Canada, for instance. It is nice to be
part of an international team of experts
who are concerned with the challenges
of water quality and wastewater pipe
rehabilitation.

Complex at Faith
Place Apartments
Oliner System has through the past two years worked on an introduction
of the products in Canada. Within this timeframe Oliner System Canada have
rehabilitated pipes in The University of Toronto and has now rehabilitated the
first residential complex; Faith Place Senior Apartments in Oshawa, Ontario.
FaithPlace is a non-profit 12 story senior
citizens apartment building complex built
in 1981.
Oliner System got the contract of pipeline rehabilitation of the buildings very
complex bottom pipe structure. The
project was complex as there were quite
a few pipes that had to be changed in
addition to the relining.
– The major part of the work took 6
weeks to complete, this included the
necessary bypass of the flow to allow
for lining and the building to maintain
service, PVC re-piping was also done in
this time for connections that were accessible and not passing through walls.
Maintaining a safe and effective bypass
was a big challenge, we had night watch
on all pumps to ensure there were no
issues, says project manager with Oliner
System Canada, Milan Pavlovic.

Fantastic job
– Milan has done a fantastic job in the
management of this project”, says
Stian Tolnæs, CEO for Oliner System
Internaional.
– Together with our experienced people
in Norway we prepared, calculated and
planned the project together with Milan,
to ensure that all specifics were accounted for. As this is our first building project
in Canada, we wanted to make sure we
didn’t get any surprises.
The project was to rehabilitate all of the
overhead horizontal sanitary and storm
pipes and connections in the basement
of the building.
There was a total of 30 plus “Y” connection to rehabilitate, connections that
were reline with PVC to eliminate unnecessary lining. Top hat installations were
done during the course of lining.
The conditions of the pipes
were extremely poor. When the pipes are
in such poor conditions, the pipe system
will improve considerably. Not only will
the pipes be reinforced and in better
condition, the waste water will also flow
much more efficient.
The target for Oliner System
Internaional
is to continue to perform similar projects
in Canada.
-We continuously work to improve our
products and methods, enabling us to
have the desired competitive advantage,
says Tolnæs.
– We congratulate Milan and Oliner
System Canada with a well performed
project and we will do everything we
can to ensure a healthy business for our
Canadian operation.

Oliner System
ready for the
Netherlands
Oliner System International’s overall strategy is to establish a number of
international locations every year. In addition to the mentioned establishment
in Northern Sweden, the company has succeeded in 2014 in establishing a
company in the Netherlands with headquarters outside Amsterdam.
Jonathan Lindenburg, CEO of the newly
established company Oliner System
Nederland, has a positive outlook for
the future of pipe renovation in the
Netherlands.
“Through my last job and six years as
sales manager at Insituform, where I
worked primarily on the municipal market in the Netherlands, I have learned
a great deal about this industry. Oliner
System has extremely good technical and
marketing solutions for a market which
is far from being as developed as it is on
larger dimensions in the municipal market. With the foundation Oliner System
represents for smaller dimensions and
industrial and personal purchasing
groups, I am convinced that it is possible
to build a sound business equal to what
Oliner System has done in other international markets,” says Lindenburg.
Jonathan Lindenburg also represents
Fibrwrap, which has good solutions for
spot repairs for everything from pipes to
complex bridge structures.
“Through the network that is being established through our Fibrwrap product,
we will get access to a great deal of
potential work for Oliner System as well.
Considering everything, I will be able
to build a portfolio with Oliner System
where I can offer rehabilitation solutions
for a large spectrum of needs,” he adds.
Right person in the right place
With the background Jonathan
Lindenburg represents, the establishment in the Netherlands should be
considered almost ideal. The challenge
The contract
between Oliner System International and
Oliner System Nederland was signed in
connection with an industry trade show
in Rotterdam in the beginning of 2015.
Contacts were made at the trade show
which meant that several offers have
already been sent on potential jobs.
“We are planning on being operational
with necessary equipment in the beginning of the second half of this year,”
says Tolnæs. “It is important the persons
who will work with the system locally
get sufficient and good training. We are
accomplishing this through a combination of training in Norway and in the
Netherlands.”
Jonathan Lindenburg, CEO of the newlyestablished company Oliner System

in establishing international companies
is to find the right person with the
right background, says Oliner System
International CEO Stian Tolnæs.
“When you can also find someone who is
as energetic and functional as Jonathan
is, the solution is just about optimal.
When establishing all our international
companies, we have a long-term perspective. Likewise for the Netherlands.
The Netherlands is very strategically
located in Europe and can thus also be a
springboard for establishing additional
companies, for example, in Belgium,
where the Netherlands and Jonathan
already have good relationships.”
Olimb Group CEO Carl Christian Sibbern
emphasises to OMAG that Oliner System
is based on technology and solutions
originating from the company’s majority
owner, Olimb Group.
“The purpose of the international scaling
up is to capitalise on the experiences and
the development we have from Norway.
Olimb as a group also wants to be able
to benefit from the experiences gained
internationally where other participants
are operating and other competitive
situations apply. All in all, this will not
only equip us as an international player
but will also make us sharper and more
competitive domestically,” says Sibbern,
who credits Oliner System International
CEO Stian Tolnæs for the job that has
been done so far in the Netherlands.

OLINER SYSTEM AB OPENS A NEW
OFFICE IN NORTHERN SWEDEN
Oliner System AB in
Sweden is expanding
its operations and has
recently opened an
office in Norrfjärden,
in Piteå Municipality.
Piteå has a population
of nearly 41,000 and is
situated in the southeastern corner of
Norrbotten County
in the very north of
Sweden.
Martin Lindholm, Dick Johansson, Jonas
Johansson and two recently hired operators constitute Oliner System Nord AB.
Martin also runs his own pipe inspection
company, MLR Entreprenad, and Dick
and Jonas have their own HVAC company, Thelins Rör.
“We have wanted to expand our business
into pipe renewal and have been on the
lookout for products and methods that
deliver the level of quality we need. We
scoured the Internet, trade fairs and
trade journals and our interest was
triggered by Oliner System. We were well
received when we contacted the head
office in Västerås,” Martin Lindholm tells
OMAG. “Our climate and geographic
location places strong demands on both
products and deliverability. With our
experience from similar industries, we
know what customers are looking for.
Operators (from left) Rasmus Blom, Johan Andersson and Jessica Brännvall ready for new
projects for Oliner System Nord AB in Piteå.
Therefore we are very conscious about
who we want to work with,” he continues.
Lindholm and his colleagues in Northern
Sweden knows that there is a great need
for pipe renewal and that customers have
become more demanding with regard
to products, methods and execution in
recent years. “We consider this a positive
development and that is precisely why
we have been very selective and spent
a lot of time choosing which system to
work with. You have to remember that
this is a matter of craftsmanship and you
need both education and training before
you can start renewing pipes. We’ve all
received training from our colleagues in
Västerås, and our instructors included
Oliner System’s Operations Manager
Micke Bäckström and Kjell Aldar from
the parent company Olimb in Norway.
It has been a lengthy process, but we
know that there are no shortcuts in this
industry.”
The new division in Piteå completed its
first projects in early March. During the
start-up phase, Oliner System Nord AB
was assisted by Fredrik Liljeberg from
Olimb Rørfornying in Råde and Christian
Barnekow from Oliner System in
Västerås. They are among the industry’s
most experienced pipe renewal experts
in Scandinavia. “It is good to know that
we have access to such good resources,”
says Martin Lindholm. The first jobs have
been in private homes, both indoors and
ground/service piping. The pipe dimensions for these projects have spanned
from 70 to 150 mm, but new projects with
other dimensions are already coming
down the “pipeline”.
Oliner System at work in Gothenburg
Oliner System has completed its first job
in Gothenburg. The work was performed
for the housing cooperative NOL no.5.
Emelie Olsson at Oliner System AB says
it was ground and service piping, with
dimensions of 100 and 150 mm. “As
usual, we established an axillary piping
system while performing the renovation
work so residents could continue to
use their water and sewage services as
6
normal throughout the entire process,”
says Emelie.
-One of the major benefits of choosing
pipe renewal is precisely our ability to
keep everything running as smooth as
possible for residents while we work –
and we did. The positive collaboration
between the housing cooperative and
project consultant Juhani Timonen kept
everything running according to plan and
made it easy to stick to the schedule she
says.
“We like working here on the west coast,
which is not so far from our office in
central Sweden or our parent company
Olimb in Østfold. We will definitely have
more projects in the Gothenburg area in
2015,” says Emelie.
Olimb and Oliner System AB have
started an exciting pilot project
for the renovation of district
heating pipes in Märsta outside
Stockholm. The first renovation
project was completed in
November last year. Fortum
owns the district heating system,
RagnSells cleaned the piping and
Olimb/Oliner System renovated
the pipes with its proprietary
liner.
The pipes in this test are made of iron
and had a diameter of 100 mm. The renovated stretch is 70 metres long and both
the flow and return pipes were renovated. That makes a total of 140 metres of
renovated piping, according to Marketing
Manager Val Sibbern. “We used a
woven felt liner in combination with a
silicone tube and an adhesive. Based on
our experience with the adhesion and
elasticity between epoxy/polymers and
iron, we believe that silicone is a better
solution than Epoxy. Silicone withstands
temperatures of up to 260 degrees and
the dimensions we are renovating here
will withstand up to 20 bar of pressure.
The large temperature variations in a
district heating system mean that it is
crucial for us to be able to compensate
for pipe movements – both in dimension
and length,” explains Rolf Dalby, Product
Development Manager for water and
wastewater at Olimb and Oliner System.
Connecting new branches and
new pipes
“An important issue is the ability to
make connections without digging. The
adhesion ability to the outer pipe allows
us to drill holes for new branches. This
technique is largely based on our experience from our proprietary water pipe
system, D.W.Liner,” continues Dalby. The
test period from November through the
winter went exactly as Olimb’s product
developers expected. Later this spring,
there will be more tests which, together
with the results from winter measurements, will give Olimb and Oliner System
an indication of how to proceed with the
commercialisation of this product. This
may involve additional dimensions and

an efficient way to produce the liner.
Whatever happens, the fact is that the
district heating network is in need of
renovation.
Great benefits
“Pipe renovation represents a major
cost saving compared to the traditional
method of digging up and replacing
existing pipes. There are a lot of pipes
in bad condition, and they are often
located in areas where digging is difficult
and not environmentally friendly,” says
Marketing Manager Val Sibbern. “Our
collaboration with Fortum and RagnSells
has been extremely positive, and the
news titbits we have leaked have been
noticed by key individuals within Swedish
energy distribution. Now that we have
preliminary confirmations that our
materials and our methods work as we
had hoped, the future of district heating
pipe renewal looks exciting. It’s no longer
just theory, but a new and important
business area for Olimb and Oliner
System,” concludes Val Sibbern.

In the course of three years,
foreman Marcelo Rodrigues
(at right) and operator
Tommy Øvergård will visit 507
dwellings in Lyderhorn Housing
Co-Operative in Loddefjord
outside Bergen.
Olimb Rørfornying and the company’s partners have renovated pipes in about 2000
residences in Norway each of the last few years.
No magical spell
fixes all pipes
Norwegian insurance companies paid nearly NOK 1.5 billion
last year as a result of leaks in interior water mains.
Project Engineer Frode Berntzen at Olimb Rørfornying works with this
problem daily and confirms that both water pipes and sewer pipes from
the construction boom of the 1960s and ‘70s are particularly at risk in
Scandinavia as well as in the rest of Europe.
“During this period galvanised pipes were used, and plastic-coated copper
pipe was cast in place to a great extent in walls and floors. When these
pipes leak, there are big challenges for both the homeowner and the insurance company,” Berntzen says.
The largest insurance payments are related to water, but it is not only the
water mains that are at risk. The sewer mains are also involved to a great
degree, in Berntzen’s opinion. Sewer mains made in PVC and ABS plastic
from this period have shown themselves not maintain a proper condition
in the long run. There are a number of residences that can be potential,
ticking bombs.
No short-cut
There is no short-cut or magical spell that fixes all pipes. It requires experience, competence and a selection of good methods and products for each
individual challenge. It is important that the customers also become familiar with the various methods, products and solutions that are available on
the market, says Olimb Product Developer Kjell Aldar.
Pipe renovation is today a solid alternative to pipe replacement. However,
it has been difficult for customers to know what pipe renovation is and
what it involves when it comes to durability, guarantees, costs and inconvenience for occupants. In this respect, Olimb has the longest experience
in this industry in Scandinavia.

14-story-high residential blocks are being
renovated from top to bottom, vertical by

time we are finding good, smart solutions,
say foreman Marcello Rodrigues (at left) and
operator Tommy Øvergård
Report
They will perform
4000 installations
Lyderhorn Housing Co-Operative, with its 507 dwellings divided among fourteen residential complexes,
stands out in the village of Loddefjord west of Bergen. Bergen is Norway’s best-known city for tourism on
the west coast of the country. Olimb Rørfornying has good progression with renovation of all pipe work
in the 45-year-old housing co-operative, and it was due time that the work got started.
The project is so far the largest contract with a housing co-operative that
Olimb Rørfornying AS has entered into.
Lyderhorn Housing Co-Operative was established in 1970-1971. The pipe material
in the housing co-operative consists of
cast iron that has been greatly marked by
the passage of time.
“In all, in the next few years 4000 installations will be done in this project,
divided among the 507 dwellings in the
housing co-operative. Every single dwelling in this large housing co-operative
needs renovation of drain pipes, verticals
and branch pipes to all baths and kitchens,” foreman Marcelo Rodrigues at
Olimb Rørfornying confirms to OMAG.
Marcelo characterises the condition of
the pipes in the three high-rise blocks as
critical. Therefore it was important to get
started in these blocks first. There were
branch pipes and verticals that could
have completely collapsed at any time.
Therefore we must also show the greatest care when the pipes are to be cleaned
and prepared for insertion of liners, he
explains.
Two verticals are renovated at a time in
parallel in the 14-storey-high blocks.
This means that a row of 14 dwellings
has the baths renovated, while the other
row renovates the kitchen vertical. In that
way, all dwellings have access to water,
including while the pipe renovation and
subsequent work from electricians,
plumbers and carpenters is going on. No
occupants need to move out, but mobile
shower and toilet units are set up which
the occupants must use when the bathroom’s vertical is being repaired.
Solid planning
Planning and good communication with
collaboration partners, the housing
co-operative’s construction manager and
the individual occupant are enormously
important if we are going to reach the
finish line at the time that has been decided, says Marcelo.
In addition to their own work assignments, the pipe renovators must also
keep a sharp eye on plumbers, electricians and carpenters who are a part of
the job crew.
It is Olimb that is responsible for the
progress plan.
“In addition to being pipe renovators, we
also have to deal with the people who
live here. After all, they are the ones
we are actually working for, and so it is
important that we have a good dialogue
with every single occupant,” Marcelo
emphasises.
About 1500 occupants are involved in this
project in Loddefjord in Bergen.

23-year-old liner good
as new at Gullfaks
Twenty-three years
have passed since Olimb
installed its first liner
at Gullfaks A in the
North Sea. The job was
done for Statoil and was
Olimb’s offshore debut.
A recently completed
status check of the liner
shows that it is in just as
good condition as when
it was installed.
This is good news for us, says Olimb
Offshore CEO Peer-Christian Nordby.
The liner was installed after two fullscale tests in Råde, Norway, and there
was great suspense associated with the
job because the operators had access to
the pipe from only one side. For this reason, the installation had to be performed
as a so-called blind shot. It was a new
method for Olimb in 1991.
The pipe extended from one of the legs
on Gullfaks A and into an inner tank that
was mounted inside an outer tank. In
other words, there was no access from
more than one end.
Statoil had recorded considerable corrosion in the pipe in question and wanted
to buy time to avoid an immediate stop in
production. They hoped the liner would
be able to hold at least six months and
a permanent solution could be found
during this period.
Laminated flange
It was in the beginning of November last
year that Olimb received a new inquiry
from Statoil after the pipe in question
had been disconnected inside the leg of
the platform. It turned out that the pipe
flange was severely corroded. In 1991,
flanges were not sealed as is done today.
Now two of Olimb’s employees, Terje
10
Terje Wold (at right) and Rolf Dalby examines the lamination of the flange on the pipe that was
installed twenty-three years ago. Statoil hoped the pipe would hold for six months, but shows to
hold for many more years.
Wold and Rolf Dalby, have found ways to
laminate them, and the pipe that Statoil
had hoped would hold for six months
can hold for many more years, Nordby
believes.
Sustains the loads
“Now we have documentation that our
liner has sustained the fluid that has
gone through the pipe the last twenty-three years. It inspires us to perform
further research and development in
the offshore area. Currently we are
looking forward to a thorough inspection
at Statfjord B where we conducted
an extensive job of pipe renovation in
a manifold in 1992. This pipe will be
opened next year, and we have reason to
expect that the liner also here is in good
condition. If this is proven correct, our
liners have had a longer lifespan than
the original pipes, which again opens up
new opportunities for pipe renovation
offshore” Nordby concludes.
About Gullfaks
The Gullfaks field is located in Block 34/10
in the northern part of the North Sea.
The main field has been constructed with
three large production platforms with
concrete jackets.
The Gullfaks A platform started production on December the 22nd, 1986,
Gullfaks B on the 29 th of February 1988,
and Gullfaks C on November 4th, 1989.
The oil that is produced is loaded into
buoys at the field, while the gas is transported in a pipeline for processing at the
gas facility at Kårstø in Rogaland. The
gas will be exported.
Gullfaks A is also used for storage and
shipping of stable crude oil from the
fields Vigdis and Visund.
Oil and gas from Gullfaks B is transferred to A and C for processing and
storage.
Since June 1994, Gullfaks C has received
and processed oil from the field Tordis.
The production record at the field was
set on October 7th, 1994 and consisted of
605,965 barrels of oil.
The satellite fields Gullfaks Sør, Rimfaks,
Skinfaks and Gullveig have been constructed with underwater wells that are
operated remotely from the Gullfaks A
and C platforms. (source: Statoil)

renovate a pipe that extends from
a collection through and under
the drilling derrick and down to
the storage tanks.

This is a repair with liner of a pipe that is
called “shale shut”.
It is primarily water that runs through
the pipe, and the water can contain a
little mud and oil that comes up through
the drilling.
The job had two parts. First, it was the
northern part of the drilling derrick
that was to be renovated, secondly
the southern part to be done later this
year, reports Olimb Offshore CEO PeerChristian Nordby.
Gone with the wind
The job has been a challenge because of
the rapidly shifting weather conditions
and several stormy days in the North
Sea. This caused some delays in the
progress. The insertion point for the pipe
renovation had itself been very exposed
to weather. The tripping-in unit actually
was on the skid on which the drilling
derrick moves, reports Olimb team leader Rolf Dalby, who has Thomas Sletne
Johansen, Jørgen Adamsen and Terje
Wold with him on the job.
