Update |market
Growing global energy demand andthe ever changing dynamic of the Oil
& Gas industry makes for anoptimistic future for the pipeline
industry, writes Noru Tsalic
The global market for steel pipe coating was worth
around 5.5bn in 2012, with oil and gas pipelines
accounting for the greatest part of this value. On the
face of it, this may be interpreted as overdependence on
one particular market. Strategically speaking, then, it
could be asked if that overdependence is a significant
risk for the pipeline coating industry? Crude oil and
natural gas are primarily used as sources of energy. But
will the world need more energy in the long run? We
hear every day about efforts to reduce the consumption
of energy.So it is reasonable to ask whether the world will use
less, rather than more, energy in the future? And
whether that energy will come from oil and gas? After
all, the trend appears to be one of moving away from
fossil fuels and towards sustainable sources of energy.
Finally, even if the world continues to use oil and gas to
produce energy, does that mean that more pipelines
will need to be built? Mankind has been building oil and
gas pipelines for decades now. Are there enough
already?
This article will focus attention on each of these
questions and attempt to provide answers based on
facts, rather than impressions.
Firstly, will the world need more energy? As the
price of energy increases and the environmental issues
receive more attention, numerous efforts are beingmade to reduce the consumption of energy in every field
of human activity. This has been going on for many
years now and is certainly likely to continue. Yet an
analysis of the energy demand shows that consumption
has increased, not decreased. This is because, while on
one hand mankind is attempting to reduce consump-
tion, on the other hand economic growth increases the
demand for energy (Figure 1). In fact, it can be shown
that there is an excellent correlation between the two
(Figure 2). This should of course be obvious: economic
activities are ultimately about creating value; and it is
impossible (the laws of nature preclude it) to create
things without using energy in the process.
Economic growth is a must, of course, if mankind is
to progress and prosper. In fact, if anything, faster

market | Update
economic growth is needed in order to remedy many of
the worlds current problems. It should not be over-
looked that a large proportion of the worlds population
still lives in poverty and under-development, deprived of
basic needs such as safe drinking water, decent
sanitation, access to electrical power, etc. And, given
that the worlds population continues to grow, outputs
need to be increased just in order to maintain the
existing situation. In summary, this means we are likely
to see a more or less continuous increase in world
demand for energy.
So, will the world need more Oil & Gas? In recent
years, sustainability topics have increasingly come to
the forefront of public debate. Among them is the issue
of energy: there is increased usage of sustainable
energy sources such as hydroelectric energy, solar and
wind power, etc. This is certainly a positive develop-
ment, in so far as it also makes economic sense. But a
glance at the data shows that sustainable sources of
energy represent a very small proportion of the current
energy mix (Figure 3). Furthermore, even in the mostoptimistic scenarios, renewable energy sources (despite
achieving considerable growth) are expected to remain
a minority for the foreseeable future.
This leads to the question, will the world need
additional pipelines? Pipelines are built primarily to
gather, transport and distribute crude oil, natural gas
and products resulting from their processing. As
mentioned, many such pipelines have been built in the
course of recent decades. So why would we need any
more?
Firstly, it should be noted that the demand for oil and
gas is still growing (Figure 4). That in itself would
indicate that additional pipelines are needed. But the
growth in Oil & Gas demand is hardly the sole (or even
the most important) driver of new pipeline construction.
A dynamic industry
Oil & Gas production is a very dynamic industry. On
one hand, the reserves held by each field and basin
are finite at some point they inevitably start to run
out; on the other hand, new basins and new fields are
discovered and brought into exploitation. Obviously,pipelines are not mobile: they cannot be simply moved
around. New fields mean new pipelines, even if that
new production replaces older fields that have run
dry. In fact, it is more than that because the low
hanging fruit has already been picked. New fields
tend to be more difficult to access: deeper under-
ground or under the sea, farther offshore or situated
in more inhospitable and/or remote regions. This
often translates into longer pipelines and more
complex coating systems.
All this is true even of conventional Oil & Gas
reserves. Crucially, however, entirely new, unconven-
tional sources are being brought into play (Figure 5).
Bituminous sands have been exploited (especially in
Canada) for a number of years already. Tight gas and

Update |market
coal seam methane are also being increasingly
exploited. Tight oil is having a huge impact in terms of
new production (Figure 6). However, perhaps the
biggest impact is that of shale gas. Huge reserves of
natural gas are embedded in a particular rock forma-
tion, called shale. A relatively new technique, known as
hydraulic fracturing or fracking, is able to release a
large proportion of that gas. In simple terms, the
technique involves directional drilling into the shale,
followed by the injection of large volumes of water at
high pressure. The jet of water (containing certain
chemicals and sand) causes micro-cracks to develop
and propagate through the shale. The gas is released
through these micro-cracks and is collected at the
mouth of the well.
Exploiting shale
The exploitation of shale gas has boomed in recent years
in the US, dramatically changing its position in terms of
energy supply and demand. So unexpected was this
change that, just a few years ago, large investments
were made in Liquefied Natural Gas (LNG) terminals.
Faced with the decrease in its domestic production of
natural gas, the US was preparing the infrastructure for
long-range imports of gas. Not only were such imports
rendered unattractive by the local production of shale
gas; some of the terminals are, in fact, being reversed in
order to allow LNG exports.
This is not likely to remain an exclusively North
American phenomenon. A recent study commissioned
by the US Energy Information Agency shows there are
huge reserves of shale gas distributed around the
globe. Although both were slower off the mark than the
US, China and Europe may soon follow in its steps.
Considerable shale gas reserves are located in Chinas
Szechuan and (especially) Xinjiang provinces; in Europe
reserves have been found in Eastern and Central
Europe, as well as in the UK (Figure 7).
While the full potential of shale gas is still many
years away from being fully exploited, there is already
renewed interest in shale oil. The technologies for
exploiting this resource are available and have been

used in the past. Shale oil was rendered uneconomic by
the advent of cheap Middle Eastern crude, but a
combination of new technologies and an increase in the
price of crude may well change that in the future.
All these changes in Oil & Gas supply are powerful
drivers for pipeline construction. So are changes on the
demand side - the fast growing manufacturing output in
Asia and South America, for instance, results in
increased demand for energy. This, in turn, drives the
construction of new pipelines.
Securing future supplies
However, new pipeline construction is not only driven by
the growth of Oil & Gas volume that needs to be
transported. The need for supply reliability acts as an
amplifier of demand. Since Oil & Gas represents a
strategically important resource, countries are often
interested in diversifying sources and routes of
transportation. Europe is a good example in this
context. Technically, Europe may be able to source allits natural gas needs from Russia. In reality, however, it
has sought to also access sources in North Africa,
Central Asia and the Middle East. This has had the
effect of driving pipeline construction activity beyond
that which would have been strictly necessary to
transport the volumes.
So far, we have been discussing new pipelines. But,
as already mentioned, mankind has been building
pipelines for many decades now. Some of these
pipelines are already old and need to be repaired,
rehabilitated or replaced. This kind of activity is gaining
in importance in the pipeline industry.
In addition, while this analysis has focused mainly on
Oil & Gas pipelines (which currently account for the
lions share of the total), there is also considerable

growth in the construction of pipelines carrying potable
water and water-based liquids. To start with, the
sources of fresh water are very unequally distributed
around the globe. Some countries and regions suffer
from water penury a situation that is further exacer-
bated by climate change, population growth and
desertification. Solutions involve either transport of
water from other regions, or desalination. Both
solutions involve the construction of pipelines.
In the slightly more distant future, we are also likely
to see numerous pipelines transporting carbon dioxide.
As previously mentioned, the world is far from being
able to wean itself away from fossil fuels. On the other
hand, continuing to burn such fuels produces CO2, which
adds to the greenhouse effect and causes climate
change. Part of the solution is a technology called
Carbon Capture and Storage (CCS). This involves
capturing the carbon dioxide produced by power plants
and storing it, for instance in exhausted Oil & Gas fields.
Between source and storage site, the pressurised gaswill be transported through pipelines.
In summary, there are plenty of reasons to answer
the third question of our analysis with a confident
affirmative: Yes, the world is likely to need many
additional pipelines. The pipe coating industry can look
to the future with optimism.

European pipelines | analysis
A number of major
European gaspipeline projectsemerged over thepast decade. Butwith the continent inrecession,NicholasNewman considers
the outlook for theseschemes
PHOT
O:NORD
STREAM
Over the past decade and before the 2008 financial
crisis consortia comprised of energy companies,
investment funds and government agencies developed
ambitious proposals to construct major new pipelines
across Europe. With Europe now in recession, questions
over the financial viability, operational sense and even
the need for such a large expansion of capacity are
emerging.
Russias Gazprom and the European Commission
(EC) were among the principle instigators in these
schemes. Today, Gazprom supplies one-quarter ofWestern Europes gas requirements. It has proposed at
least three mega pipeline projects to connect its Arctic
gas fields in Siberias Yamal Peninsular with Western
Europe in order to provide sufficient capacity to meet
Europes future needs, maintain market share and to,
perhaps, divert gas transmission to Western Europe
away from the Ukrainian pipeline network.
Meanwhile, the EC has produced a rival plan for a
mega pipeline to link Central Europe, via Turkey, to the
gas fields in Central Asia and the Gulf Region. It also
plans smaller fill-in projects to make up for gaps in
the existing pan-European pipeline network in order to
create a single European gas market.
These pipeline schemes shared the one major
assumption that European demand for gas would rise. In
2006, for instance, Eurogas predicted demand would rise
43% by 2030, from 438 mtoe (million tonnes of oil
equivalent) in 2005 to 625 mtoe in 2030 (1). More recently,
the IEA World Energy Outlook 2012 forecast that,
because of declining output from European gas fields,
Europe would need to increase imports of gas from 302
bcm (billion cubic metres) in 2011 to 554 bcm by 2035 (2).
Much of this increase in demand is expected to derive
from expanding Europes power generation sector.
Unfortunately for Europes pipeline investors,
however, the demand for electricity in Europe hascontracted by 1.2% per year since 2008, according to the
ECs Quarterly Report on European Electricity Mar-
kets(3). This drop in demand has been especially marked
in energy intensive industries such as steel, pharma-
ceuticals, plastics, fertilisers, construction, cement and
chemicals, which have been burdened by both a
contraction in home demand as well as price un-com-
petitiveness with American counterparts benefiting
from the shale energy revolution.
Given the extent of Europes crisis and Americas
improved competitiveness, this could mean a perma-
nent loss in capacity. In many European countries,
including France, Germany, the Netherlands and Spain,
gas power plants are failing to break even. In part, this
is due to the success of Europes renewables policy.

This has cut into both base load and peak load demand
the most profitable for gas power generation.
Moreover, the price of coal has fallen at a time when
gas and oil prices have risen, leading to a dash for
coal in power generation in some countries. As a
consequence, many gas power stations are on short-
term working or are being mothballed and gas power
utilities experiencing a declining share of a contracting
market have put plans on hold for new plants. Un-
changed, this could reduce the need for gas imports
from Russia, and hence the additional pipelines.
Furthermore, Europes climate and environmental
policies aim to increase the contribution of renewables,
throwing further doubt on the need for Russian pipeline
expansion. And potential future exports of LNG from theUS shale gas industry to Europe could depress Euro-
pean gas prices by at least 3%, raising more questions
over the long-term viability of many of the new pipelines
into Europe. European shale gas production in Poland,
Germany, France, Italy and the UK, should it be
realised, would further depress imported gas demand.
This combination of long term weakness in demand
for gas together with the prospect of potentially growing
shale gas supplies raises questions over the viability of
some of the planned new pipelines.
In 2012, Gazprom exported 203.22 bcm of Russian
gas to Europe. Current pipeline plans will raise Russias
export capacity to 380bcm, according to Rovshan
Ibrahimov, head of international relations at Qafqaz
University, Azerbajan(4).
According to Carlo Malarcarne, CEO of SNAM (the
Italian natural gas infrastructure company): It is
difficult for suppliers to sign long-term contracts with
Europe because there has been an over-supply of gas
since the financial crisis.
Professor Jonathan Stern, at the Oxford Institute for
Energy Studies says: Gas demand is in free-fall
virtually all over Europe; what new capacity do we really
need?
Many of these gas pipeline projects have been
delayed due to difficulties in finding sufficient capital to
commence construction. Traditionally, banks have
accounted for around 75% of infrastructure funding with
the rest coming from governments, sovereign wealth
funds, investment and pension funds. The financial
crisis has reduced the amount of available funding and
increased its cost. Even Gazprom, with political backing
from the Russian state, relied for a third of the Nord-
stream pipelines funding on international shareholders
within the Nord Stream consortium: Gazprom, Winter-
shall, E.ON, Ruhrgas and Gasunie. Half of the remain-der came from commercial bank lending, and the rest
from export credit agencies(5).
Funding difficulties are likely to increase when
European banks raise their capital ratio requirements
at the end of this year. To add to the difficulties of
fundraising, Stern predicts that some of the projects
may never recoup their investments. Nobody wants to
invest in a project which is not going to at least break-
even within a reasonable time, he points out.
The Nordstream pipeline project is designed to
directly link Russia, via the Baltic Sea, to the heart of
the European Union. Once complete, it will consist of
four parallel pipelines running from Vyborg near St
Petersburg to Lubmin on the North East German Baltic
coast. Phases 1 and 2 of this 1224 km pipeline network
were completed in 2012 at a cost of 7.4bn(6). It is
expected that Phases 3 and 4 will cost a similar
amount. Once fully complete, Nord Stream is designed
to transport 55 bcm of Russian gas every year to central
and Western Europe.
The design of the route for Nord Stream has not
been without difficulty. Planners have had to bear in
mind the existing complex network of subsea electricalcables, oil and gas pipelines that criss-cross the Baltic
seabed. In addition, the seabed is not flat and in parts
there are significant obstacles, ranging from natural
rocky outcrops to man-made hazards such as unex-
ploded munitions. As a result, the seabed route has had
to be adjusted several times(7). At present, Nord Stream
is conducting a series environmental and social impact
studies for Phases 3 and 4 to be submitted for approval
to regulators in the Baltic States.
The building of Nord Stream 3 and 4 is likely to use
the same construction infrastructure as for earlier
stages. The completed project will use the Portovaya
compressor station in Vyborg near the Gulf of Finland
for front-end gas boosting.
In 2010, Ukrainian pipelines accounted for 80% of

Russian gas destined for Europe(8). UkrTranzGaz, the
Ukrainian pipeline operator, has estimated that on
completion of Nordstream, the Ukraine is likely to lose
some $720 million per year in transit fees.
Nabucco is the European Unions priority pipeline
project designed to reduce dependency on Russian gas.
It aims to construct a pipeline from the Baumgarten gas
hub in Austria to Turkey. The pipeline infrastructure
will consist of main, local and sub control centres,
compressor stations, custody transfer bordering
metering stations, intermediate take-offs, cathodic
protection stations, pigging and block valve stations,
SCADA and a fibre optic telecommunication system(9).
In Turkey, it is planned to link with pipelines exporting
gas from Azerbaijan and eventually the Gulf.If constructed, the route will consist of a 3,900 km
pipeline, which will be able to transmit 23 bcm of gas
per year to Europe. However, since its conception in
2002, this project has faced numerous delays and
setbacks. There have been problems in obtaining
sufficient political and financial backing, as well as
securing sufficient gas supplies. This year alone, power
utility RWE, one of the projects major backer, sold its
shares in the pipeline project to Austrias OMV.
For the future, both Hungary and Bulgaria have
announced that the Nabucco gas pipeline project has
successfully completed its environmental impact
assessment process(10). More significantly, due diligence
awaits completion from its backers, including the
European Bank for Reconstruction and Development,
the International Finance Corporation and the European
Investment Bank. In June, an agreement by the
Azerbaijan government is expected to ship gas from its
massive Shah Deniz Phase 2 offshore gas fields in the
southern Caspian Sea(11)via the Nabucco pipeline to
Europe, thereby ensuring sufficient gas.

analysis | European pipelines
Gazproms Yamal Europe 2 project is designed to
carry 50bcm of gas a year from Russia via Poland to the
central European states of Slovakia, Hungary and
Austria. It still awaits Polish approval to cross its
territory(xii). However, Poland has little to gain apart
from transit fees because of improved integration with
the European gas network and the soon-to-be opened
LNG terminal at Swinoujscie.
It is becoming increasingly clear that the financial
viability of many of the proposed gas pipelines from
East to Western Europe is uncertain. If built, some could
be destined to become white elephants potentially in
the wrong place and maybe even pointing in the wrong
direction. With money for these mega projects scarce
and expensive, it is possible that Europe may turn its
attention over the coming years to the construction of
shorter pipelines that fill the gaps in the existing
network.

Lifetime testing | technical paper
PHOTO:STATOIL
Polypropylene foam has been used as a thermal
insulation material for over 20 years and a good trackrecord has been built up over that period. Statoil recent-
ly decommissioned its Tordis field after 20 years of
operation and sections of line pipe and field joints were
retrieved for testing of corrosion attack on the steel
pipe. Sections were also made available to Bredero
Shaw for testing and analysis. This is the first time that
testing has been able to be performed on real samples
after the full field life and serves as an acid test for the
validity of the assumptions made in the selection of
materials and the design of the system. Both mechani-
cal and chemical testing was performed on the
retrieved coating samples and the results are reported
in this paper.
The Tordis field was originally developed by Saga
Petroleum and came on stream in 1994. The field is in
Block 34/7 in the Tampen area of the Norwegian North
Sea. The water depth was 200m and the design operatingtemperature was 70C. The insulation coating was
applied to a 275 mm OD pipe, with a wall thickness of
15.9mm and the total system (all layers) was applied at a
thickness of 50 mm. The design lifetime used for the
Tordis project was 20 years.

of the Thermotite system and the coating was per-
formed in KWHs plant in Vasa, Finland, in 1992. The
application process, although no longer used, was as
follows:
Step 1:
Cleaning and blasting of steel;Heating of steel and application of FBE and powder
adhesive.
Step 2:
Application of adhesive, foam and outer shield by
cross head extrusion to cold pipe;
Induction heating to fuse the materials applied in
Step 1 to the materials applied in Step 2.
The field joint process was an early version of the
IMPP process. One facet of this process is that the use
of the induction coil to fuse material resulted in a region
within the insulation layer, close to the FBE / adhesive,
where the foam density is higher than the core of the
foam layer.
The Tordis line pipe insulation system was built up
as follows: FBE (300 micron); Adhesive (700 micron); PP
foam (density 700 40 kg/m3, 45 mm) BA202E; Solid PP
shield (4 mm) Borcoat EA165E. The Tordis injection
moulded polypropylene field joint was built up as
follows: FBE (300 micron); Adhesive (700 micron); Solid
PP (56 mm) Borcoat EA165E.
Samples and analysis
As the Tordis project was a milestone for subsea
polypropylene foam (PPF) technology, several samples
were retained as demonstration pieces. These have
been kept in office conditions and thus not exposed to
compressive loads, thermal loads or environmentalstresses. These have been used in the current paper as
reflecting the initial state of the produced insulated pipe
(t=0).
The end of life sample was retrieved as part of a
corrosion study and 2m of the retrieved section included
a section of the injection moulded polypropylene (IMPP)
field joint.
Operational data supplied by Statoil indicates that the
sample had been operated close to the design tempera-
ture for a significant part of the field life (Figure 1).
In order to determine the extent of change in the
materials it is important to address aspects of change
in the material at the molecular level. The following
techniques were used:
Gel Permeation Chromatography - providing
information on change in average molecular weight and
molecular weight distribution.
Melt Flow Index measurements - providing a single
point viscosity measurement indicative of changes in
molecular weight.
In order to determine change in mechanical
properties the following techniques were used:
Three-point flexural testing.Uni-axial tensile testing.
Oxygen induction time measurements were also
performed to determine the level of residual anti-oxi-
dant in the samples and thermal conductivity was
measured on the exposed foam samples and compared
to the design curve for the material to confirm whether
the 20 year design assumptions were met.
Where possible, tests were performed on both
exposed and unexposed samples. However, due to the
shape and quantity of the unexposed samples this was
not possible in all cases.
GPC test results
Gel Permeation Chromatography (GPC) analysis was
carried out according to ISO 16014-1, 2 and 4, 140C,

trichlorobenzene solution. GPC is a fractionation
method aimed at gaining information concerning the
molecular weight distribution within a sample of
polymeric material.
Analyis was performed on exposed and unexposed
samples of both the foam and field joint material. For
comparative purposes, the molecular weight (Mw) and
the number average molecular weight (Mn) were
determined, from which the polydispersity index (PDI)
was determined as Mw/Mn. [Mw is the average weight
of polymer chains in the sample weighted according to
weight fractions, Mn is the average weight of polymer
chains in the sample weighted according to number
fractions, PDI is a measurement of spread in the
molecular weight distribution within a sample.]Significant chemical change, such as cleaving of
polymer chains, would be expected to change the values
of Mw and Mn and to narrow the PDI.
The results are shown below in Table 1 and Figure 2.
Samples from the exposed section were taken from the
hot region of the field joint during operation. The values
of Mn and Mw for exposed and unexposed samples are
identical within the uncertainty of the measurement
and, as can be seen in Figure 2, the GPC curves for
exposed and unexposed samples lie on top of each
other for both the line pipe and the field joint materials.
Therefore, at the molecular level there is no evidence of
significant change.
MFI test results
Melt Flow Index (MFI) measurements were carried out
according to ISO 1133; 230C, 2.16 kg load. MFI is a
technique that is used as a QC tool to determine whether
a material has the same melt behavior under a given set
of conditions.
As the rheological properties of polypropylene
materials are dependent on the molecular weight and
the molecular weight distribution at a given tempera-ture and under a given loading, this simple tool has
been used to indicate change. Although not as exhaus-
tive in terms of data as the GPC analysis performed
above, the test is simple and cheap to perform and the
results are generally more available to the reader.
Increase in MFI is assumed to be indicative of reduction
in average molecular chain length and thus degrada-
tion.
MFI results are shown in Table 2. As with the GPC
analysis, there is little evidence of significant change in
the MFI of the materials pre- and post exposure. While a
slight increase in MFI can be seen between the exposed
and unexposed foam, the significance of this relative to
the accuracy of the measurement is questionable.
Oxygen induction testing
Oxygen Induction Time (OIT) measurements were
carried out according to ISO 11357-6; 210C, O2. OIT
reflects the amount of residual anti-oxidant additive
present in a material. For many materials the presence
of such additives is essential to prevent oxidative
cleavage of polymer chains and the corresponding
reduction in mechanical properties. OIT is often
measured following material application to ensure that
suitable processing conditions have been used.
The question of change in OIT in the subsea environ-ment is often asked and, until this point, little material
has been retrieved for analysis. In the Tordis case,
however, samples were available for analysis post
application and post exposure. The results in Table 3

show there is no significant change in the values
measured and, as such, no loss in stabilization over the
20 year operation of the line.
Three-point flex testing
Three-point flexural testing was carried out in accord-
ance with ISO 178. Due to the availability of suitably
sized samples this testing was limited to the exposed
material and the raw material properties are used for
comparative purposes. As such, the degree of changefrom produced article to exposed article is not known.
This comparison is, however, useful to address the
overall change from raw material. From the data
presented in Table 4 it is clear that there has not been
any significant change in properties from the initial that
could be considered injurious to the performance of the
insulation and field joint systems.
Tensile test results
Uni-axial tensile tests were performed on samples
retrieved from both the exposed and unexposed
specimens and in accordance with ASTM D638-03; type
IV specimens, 50 mm/min at 21C. Tensile bars
measuring 12 mm x 8 mm were used to reduce the
impact of the foam structure on the ultimate elongation
(elongation at break) of the materials. This is sufficient
for a comparative study. However, as can be seen in the
right hand column in Table 5, the data is still associated
with very high standard deviations relative to the mean,
and graphical information is more informative. Tensile
stress-strain curves are included for that reason later
in Figure 3.
From Table 5, it can be seen that the yield stress and
stress at break have reduced for both sets of samples
post exposure. The fall is relatively small, but signifi-cant. As there is no evidence of chemical degradation in
the polymer from the GPC study, this reduction may be
a long term effect of the development of the thermody-
namic phase/morphological structure of the material
over time post-application.
Elongation at yield is affected only slightly for both
sets of samples over time, as is also the case for
extension at break when the effects of premature
failures are taken into consideration in the interpreta-
tion of the results (Figure 3).
Thermal conductivity
Thermal conductivity was measured for the exposed
material and compared to the current design curve for
BA202E at 660 kg/m3. The results are shown in Figure 4,

Russian company CELER marked a milestone last year with theproduction of its one millionth welded pipe joint protection sleeve.
It is now working to meet even more demanding goals
Russian company CELER celebrated a milestone in its
history last year: the production of its one millionth
internal weld joint protection sleeve for steel pipes.
Developed to protect the exposed surface at the
welded joint area on steel pipelines with an internal
anti-corrosion applied coating, CELERs CE pipeline
internal welding joint protection sleeve is simple to use
and, due to its elastic rubber collar sealing system, is
suitable for use with all grades of pipes. The sleeve, the
intellectual property of CELER, is both the companys
that has laid the ground for all of its ongoing develop-
ments.
CELER manufactures two versions of the CE pipeline
internal welding joint protection sleeve: one for the oil
industry or for industrial/waste water applications; and
one for potable water. Both variants carry all the
necessary certifications and are supplied complete with
the companys CH-5-A mastic sealant (the price of this
is included with the sleeve). This mastic also carries all
the necessary certifications (including hygiene) and may
be applied in oil as well as potable water pipeline
applications.
One million installed sleeves manufactured,
supplied and installed over 14 years means
10,000 km of oil pipelines with internal
corrosion-resistant coating are benefiting from
CELERs joint protection technology. That is the
equivalent to a distance of one quarter of the
worlds equator, the company says.CELER was established in February 1999,
commencing operation with just 400m2of
production space. In those early days, the company
carried out only assembly work, outsourcing its
engineering requirements to a number of aircraft
manufacturing plants. Maximum production capacity in
the first year was 100 sleeves a day.
The decision was taken in 2001 to stop
outsourcing and begin in-house production.
CELER began manufacturing its own
blanks, setting up its own welding, coating
and rubber production units. Capacity in the
first year of in-house manufacturing was
35,000 to 50,000 sleeves a year. Today, the
company operates from a 12,000m2

production facility and is able to produce as many as
1,000 sleeves each day, in sizes ranging from 57 mm to
1,220 mm in diameter. One factor that has played a part
in this fast production growth is the simplicity of the CE
sleeve design, which does not call for complex machin-
ing and welding processes.
When CELER first introduced the CE sleeve to the
Russian market, it was competing against a number of
alternative welded joint corrosion protection technolo-
gies, including slip casting, protectors, and stainless
sleeves. At that time, Russian oil companies had no
particular weld protection preference. However, within
five years, the sleeve had proved itself to be the most
efficient protection technology in terms of reasonable
pricing, reliable performance, and easy installation (the
collar and two design variants means the CE sleeve can
be installed on any pipe grade without the need to
calibrate the pipe ends). By 2012, CELERs sleeve
production volume had grown to 200,000 units a year.This rapid growth in demand for sleeves lead the
company to begin production of a range of pipeline
accessories, such as the Ch-5-A mastic and a complete
line of special fittings (including pipe-bends, reducers,
T-joints and flanges with anti-corrosion coating and
weldolets that are connectable to the sleeves). Several
of these special fittings and mastics are also patented.
During the first five years, CELER exploited its
growing income to equip itself to manage the entire
production cycle for manufacturing sleeves, mastic and
various fitting types in-house. The company has
continued to grow since by expanding its production
capacity and increasing its production areas. Each year
a new production shop is added to the manufacturing
facility.
The company has also worked to continually improve
the CE sleeve design and quality. In 2005, it introduced a
new collar (which is patented separately) which is
easier to install and achieves a tighter fit. The mastic
formulation was also improved, allowing its shelf life to
be extended from six months to eighteen months to
meet the increasingly demanding requirements of
customers.
In the same year (2005), CELER also obtained a
Certificate of Conformity of the Quality Management
System to GOST R ISO 9001-2008. This conformity has
been successfully renewed each year and the company
proudly claims that it has not received a single quality
complaint since then.
CELERs customer list includes almost all of
Russias major oil companies. Long-standing custom-
ers such as TNK-BP, Lukoil and Rosneft, have more
recently been joined by Tatneft, Bashneft, Gazprom, and
Slavneft. Two years ago, CELER also started workingvery closely with Surgutneftegaz.
A key strategy in the companys business develop-
ment has been to collaborate closely with design
institutes. This enables it to ensure that its products are
included in new field development projects such as the
construction of field oil pipelines as early as possible in
the development stage. Currently, more than 30 R&D
and design institutes include CELERs CE range in their
projects. This includes the sleeves, as well as CE
fittings and all kinds of special parts.
In recent years, the company has also focused on
introducing new equipment to increase labour efficiency
and to expand its production capacities. A year ago,
CELER commissioned a robot-aided welding complex
supplied by KUKA, which is said to be unique in Russia.

Apart from the robot-aided
welding complex, high quality and
capacity is also ensured by means
of the companys other equipment,
which includes welding units (manufac-
tured in Finland, the USA and Sweden) and universal
welding rotators.
The company uses two package semi-automatic
units for facing operations and small diameter sleeve
manufacturing. These units were specifically designed
and manufactured for CELER, a process that took two
years. However, the end result has proved worthwhile
as the application of these units enabled the production
output of small sleeves (57 to 219 mm in diameter) to
be increased from 150 to 500 units per day per semi-
automatic unit.
The CH-5-A mastic is used as part of CELERs own
CE joint protection system, but is also suitable as a
lower cost alternative for sealing joints in pipe connec-
tions made using the Butler mechanical pipe joining
system. Supplying the mastic for use with the Butler
system required development of an automated dosing
system to increase production capacity and CELER iscurrently introducing two automated units for mastic
dosing into its packing systems.
CELER is equipped to use a variety of protective
coatings including epoxy powder, liquid epoxy and
polyurethane - which can be applied according to
different procedures approved by the client or design
engineer. All powder coatings are applied using the
electrostatic method and high-efficiency equipment
supplied by Gema of Switzerland. CELER has, however,
modified the powder coating application unit using its
own application expertise to achieve online control of
powder weight for a specific part. This has allowed the
company to achieve a high level of precision in applied
coating thickness, which has a critical influence on the
overall quality. Liquid epoxy and polyurethane paints
are applied using a high-efficient airless
spraying unit manufactured by Graco.
CELER is now building on its joint
protection expertise and expanding its
product offering to include production
of pre-fabricated process pipeline
units with internal or full coating.
The first step in this was to manufac-
ture special complex pipeline
connecting parts with anti-corrosion
insulation, such as branch pipes with
flanges and welded weldolets for
pressure or temperature gauges
connected by branch pipes of a number
of pipe-bends, T-joint reducers andsimilar parts.
The company now aims to be proficient
in manufacturing all products necessary for
the assembly of a closed oil & gas gathering
system of pipes, standard and special pipe fittings,
support units and welding joint protection sleeves. It
has completed orders for the manufacture of pre-fabri-
cated pipeline units with internal corrosion-resistant
protection, measuring and metering units, cleansing
and diagnostic agent injection/receiving units, pump
station manifolds and other process piping for field and
transit pipelines. It now considers this area to be the
most promising in the field of anti-corrosion protection
of internally coated pipelines.
The most recent addition to the CELER capability
programme is the introduction of joint insulation
technologies. The company now has expertise in the
installation of foamed polyurethane heat insulating
coatings inside a galvanised casing, which can be
appied to all of its fittings and units.
Looking forward, CELER aims to ensure it continues
to maintain its current pace of development by staying
in touch with the most recent developments in order toprovide an integrated approach to field pipeline
anti-corrosion protection and to manufacture the
highest quality products. To that end, it takes inspira-
tion from the English writer Lewis Carroll, who said: It
takes all the running you can do to keep in the same
place. If you want to get somewhere else, you must run
at least twice as fast as that!

subsea | Flow assurance
Bayou Wasco Insulations new US line pipeinsulation facility is the first in North America to
use Dows Neptune two-layer flow assurance technology
Bayou Wasco Insulation has commissioned the first
flow assurance system facility in North America capable
of applying Dow Chemicals Neptune insulation system
to oil and gas line pipe at its newly-established facility
at New Iberia in Louisiana, US.
The company collaborated with Dow Chemical on the
full-scale qualification of the process for Neptune P
insulation coating for line pipe and optimisation of the
insulation application capability at the new state-of-
the-art plant.
We are very pleased with the progress that has
been made to successfully and quickly bring this brand
new facility on-line, says Eldridge Indest, vice presi-
dent and general manager of The Bayou Companies.
The Bayou Wasco Insulation facility, which was
formally inaugurated this month, is located close to the
US Gulf Coast oil and gas markets.
We built this plant with our offshore customers in
mind, offering them favorable logistics with an
accessible location near the Gulf of Mexico.
Additionally, we believe they will be very interestedin the end-to-end and elevated temperature
insulation performance of the pipes coated with
Neptune technology that we produce, says
Indest.
Now that we have the ability to produce
coated pipes that will meet our customers
deep water insulation needs, we are ready to
discuss upcoming offshore projects, he says.
Bayou Wasco Insulation is a joint venture
established in 2011 between The Bayou
Companies and Wasco Energy. It was estab-
lished to provide offshore insulation services to
customers in North America, Central America
and the Caribbean. The New Iberia facility is
configured for application of a range of flow

End-to-end solutions
The Neptune P advanced flow assurance insulation
system for line pipe is part of a new proprietary
end-to-end flow assurance system that also includes
Dows Neptune F field joint coating and Neptune C
coating for subsea architecture. The simple, two-layer
system includes an underlay of a high temperature
fusion bonded epoxy (FBE) for corrosion protection and
an overlay of Dows advanced hybrid polyether thermo-
set insulation.
According to Dow, the hybrid polyether thermoset is
a new insulation technology developed to provide robust
flow assurance in the increasingly harsh conditions
experienced during subsea oil production. Applied over
the proprietary FBE layer, the system has passed
demanding qualification tests, including small- and
production-scale trials employing extreme testing

Flow assurance | subsea
procedures to validate compressive strength, durability,
and thermal performance.
The system is said to eliminate the need for the use
of the multiple materials and adhesive tie-layers
usually employed in flow assurance systems, which is
said to allow a thinner coating profile to be maintained
while achieving higher consistency in K-factor between
tree, to line pipe, and to field joint.
The Neptune P coated line pipe produced at the
Bayou Wasco facility is intended solely for use with the
Neptune F insulation coating for field joints. This
simple, reproducible field joint coating process was
recently demonstrated by UK-based Pipeline Induction
Heat (PIH), part of the CRC Evans group of companies,
to produce high-quality field joints on an eight inch
diameter line pipe.
PIH and Dow have a long history of collaborating to
bring innovation to offshore oil and gas production,
says Tony Pontefract, director of business development
at PIH. Through our collaboration on Neptune FInsulation, we now have the ability to offer customers a
simpler, reproducible field joint coating process,
competitive cycle time, high mobility and a compact
equipment footprint.
According to Dow, the Neptune technology provides
the widest end-to-end installation and operating
temperature range of any wet insulation system currently
available on the market. The company claims the system
offers excellent physical properties, remaining highly
flexible down to -40C and retaining its thermal stability
at service temperatures of up to 160C. The system has
been tested for use at depths of up to 4,000m.
Dow worked closely with polymer and syntactic
foam-based coating specialist Trelleborg Offshore in
development of the Neptune C component for subsea
architecture protection.
Since its introduction early last year, the Neptune
system has won a World Oil Award for Best Production
Technology and an Offshore Technology New Technology
Award.
