Seal For Life, the original slogan of Stopaq, has now become the name of our company. And not without good reason. It’s not just a slogan, but a statement we are making to the market: thanks to its ‘literally smart cross-bonds’, Seal For Life Industries is able to offer new, sustainable solutions within the oil, gas and water – i.e. pipeline – markets. Our constant pursuit of quality and way of thinking enable us to give guarantees that others simply cannot fulfill. Our synergies also enables us to take advantage of our leadership position in niche markets. For instance, we can successfully tackle the cable

joint market through a broader, yet at the same time deeper, focus on civil infrastructural challenges. Our views on markets and applications demand not only knowledge but also courage. That’s because introducing new methodologies and ways of thinking into traditional markets is a brave thing to do. But we have already noticed both within and outside Seal For Life, that our vision is leading to success: ‘Dare to Care’ is not only a slogan, but also a clear statement to our stakeholders, clients and application engineers.

As Seal For Life, we are the ‘lifeguards’ of (often) vulnerable systems, not just on land but also offshore. An increasing number of clients no

longer accept short-term solutions, but instead are convinced by our vision and can see our growth and expansion into other market areas. What’s more, through our global dedicated market management for offshore, we can also take a leading position in the field of pre-insulated

pipe plant coating and plant coating in general. By means of exclusive partnership services, we can boost sales concepts for a whole range of specific applications and uses, such as casings, j-tubes, subsea structures, surface preparation, pre-engineering, factory-applied pipeline coating concepts, storage problems, application training, corrosion monitoring and after-sale service.

Changes on our planet also offer new opportunities to put the innovative strength of Seal For Life into practice. For instance, pipeline and ‘bedding solutions’ in unstable infrastuctures, our solutions for applications in polar regions and the solutions that we as a group can offer in relation to the

This is also the world of Seal For Life. The skutsje, a more than 100 years old barge, is a populair historic boat type in the Netherlands. Every year they compete in a national race-week with tens of thousands of spectators. Good conservation of these ships can only be achieved with high quality solutions. This barge (right) has been sealed with fluid STOPAQ anti-corrosion material to seal the deepest pores and crevices. Sealed for her maritime life indeed!

rise in water levels, worldwide. This is no longer just something for the future; our Stopaq member is already carrying out applications involved with raising dyke walls in relation to these changing circumstances in the Netherlands. If there were no levees, 45% of this particular country would disappear under water.

In short, ‘Dare to Care’ is no longer limited to below-ground pipeline and traditional markets, but means ‘Total Care’ for Seal For Life nowadays. Seal For Life’s playing field has become not only very broad, but also specialised. This demands a lifelong learning process – continuing education – from engineers and application teams, but also from ourselves.

The future proof organizationwith staying powerAn organization must be ready for the future. And a successful future can only be guaranteed if that organization has staying power. The following organizational model is heartwarmingly simple and therefore very clear: its metaphor is the Christmas tree. Staying power is essential to create a healthy, green Christmas tree.

People focus is the core of staying power: people must want to work in a motivated way, they must understand and be enthusiastic about why they are doing something for the organization.

The most important aspect of the organizational model is to see ‘people focus’ in your organization as a Christmas tree:

a. The basis, the seed-bed: true, important core values for staff: what do we stand for?

b. The trunk: aim for 100% ‘people focus’ and therefore dedicated staff and satisfied clients

c. the lower part of the triangle: the support organization/engineers, who always offer support and service

d. the top of the triangle: – the ‘moment of truth’ – it’s here that the product or service is delivered

e. the star: – that’s what we all do it for – 100% satisfied clients. They are the stars!

A. The rich earth as the basis. This is the seed-bed, the nutrient (soil) and the core essence of Seal For Life Industries. It’s the fertile ground that gives the sy ner-gy its po wer, based on our SFL mission, vision, belief, attitude and approach. It’s our combined quality that must be safeguarded and constantly fed.

The trunk as transporter. Within this, the ‘people focus’ that makes the appliers happy is central. It ensures both personal growth and development, all through the ‘one fa mi ly’ mentality. Here you will also find the ambassadors (distributors and appliers) who are the messengers.

The lower part of the triangle: engineering & services. This is where the innovations and ideas come from; it’s the world wide support center. It’s an important shoot of the tree where you can also find aspects such as PQT training, certificates, partnerships (such as with Falck). But beware: it’s not headquartes. Thinking in terms of ‘headquarters’ is so old-school!

The top part of the triangle: sales & customer service. The ‘moment of truth’ for the sales orga ni sa tion. Can we turn our abilities and beliefs into reality?

The star: these are our clients. With big names we must really care for: GasUnie, Fluxys, Pemex, Petrobras, Gazprom, Eni, Chevron, Saudi Aramco, Petrochina, Statoil, QP, ADNOC, GNPOC, Sasol, Lukoil, Exxon and BP.

Be consciousPumping knowledge from roots to the trees, from human capital to society, is the simple and risky work called entrepreneurship. The term has been used in multiple and diverse ways, but few really know how to define it to generate high and sustainable growth. Entrepreneurship is not just about receiving money for new business (trees); it also needs spirit and talent (roots) to flow accordingly. It is not only science but art as well.

It is an art, or spirit, that emerges thanks to the inspiration, creativity and added value that motivates indi viduals to generate unique attitudes and behaviors. It presumes an inner cultural challenge that presently differentiates entre-preneurs with what we term ‘disruptive’ initiatives.

The key to creating a successful com bi nation of art and science, and therefore delivering tangible benefits to society, may depend firstly on building the individual and contextual conditions that permit entrepreneurs to launch in no vative projects (a new fish for example), not only by detecting the right idea (flying fish) within a huge and rapid competitive world (oceans and currents) but by managing the right moment (early in the morning), at the right place (Barbados), with the right resources (a fish caught while flying, using nets from outrigger canoes).

If entrepreneurs detect good disruptive ideas but aren’t conscious of their potential, innovation will not be fruitful. Source: Mahr Avila, EU Advisor

The three main pillars of knowledge are education, research and innovation. But are these pillars sufficient to turn an idea into a successful reality and translate benefits to society? The answer seems to be no. It does not matter how large or how many support mechanisms are visible as ‘trees’ (society), they will not work if the “roots” (education) are not adequately nurtured to prompt the knowledge flow capillaries.

Research continues on exactly what happens when two objects stick toge ther. There is no universally accepted theory and given the variety of adhesives that exist it is likely that more than one process may be at work. It is generally agreed that adhesion occurs at a molecular level with the primary processes involving Van der Waals forces, iconic bonding, covalent bond ing, and/or metallic bonding. Because the latter three processes result from chemical bonding, we will focus our discussion on Van der Waals forces.

Van der Waals forces come into play when molecules are polarized -- that is, they have a positive end and a negative end. Because the hydrogen atoms are skewed to one side, one end of the molecule has a weakly positive charge and the other has a weakly negative charge. Since opposites attract, the positive side of one water molecule will be attracted to the negative side of a neighboring one. That’s the Van der Waals force.

For Van der Waals forces to work, there must be close contact between the two surfaces being joined--a separation of only a few angstroms. (An angstrom is one ten-billionth of a meter.) At that range the Van der Waals and other molecular forces interact strongly and the adhesive and the glued surfaces bond together.

To ensure close contact, the adhesive must have the ability to wet the surfaces of the parts properly - it must spread and flow such that it maintains the maximum contact area possible, and it should spread thinly to avoid being subject to cohesive failures.

According to recent research, Van der Waals forces explain how the lizards known as geckos can stick to so many surfaces in a seemingly impossible man ner. Specifically, the tiny hairs on the gecko’s feet (called setae) are split at the microscopic level into “as many as 1,000 branches, whose spatula-shaped tips are only 200 nanometers wide.” As a result, even though the Van der Waals forces acting on an individual tip are small, the adhesion of a billion or so tips adds up to enough force to let the gecko stick to anything.

Persuasive as all this sounds, other scientists doubt that Van der Waals forces alone fully explain how adhesion works. They attribute at least some of the strength of adhesives to the process of me chanical bonding, also known as mechanical locking. The idea here is that all sur faces, even seeming - ly smooth ones, are actually rough at the molecular level, and that an adhesive achieves some of its strength by flowing into the hid - den valleys and imperfections of the surfaces to be bonded.

When the adhesive hardens, the two parts are mechanically llocked together. In mechanical bonding, as with

Van der Waals forces, an adhesive needs to be able to spread finely

into the microscopic roughness of the surfaces, wet the tiny

cracks properly, and allow trapped air to escape. The

main difference is that mechanical bonding will work at distances that would render

Van der Waals forces useless. There are several

other theories of adhesion that ought to be mentioned briefly. The electrostatic theory arose in part from the observation that some

adhesives generate static sparks when pulled apart, while other items will cling

together when placed next to each other, especially in the case of plastics. The theory proposes

that as the joint forms, electrostatic charges develop between the two joined surfaces and between the surfaces and the adhesive, and these electrical forces help hold the joint together. But electrostatic forces are believed to be only a supplemental source of joint strength, not the primary one.

In Columbia a comparative coating analysis for pipelines has been made to compare cost for various methods of protecting pipelines from corrosion.

The following methods were compared:

• The Coating 100% Solid method. Pipes are being sandblasted and provided with a primer. Finally, an epoxy coat is applied;

• The Fusion Bonded Epoxy (FBE) method. A liquid FBE film flows onto the steel surface and soon becomes a solid coating by

chemical cross-linking, assisted by heat. This can be done with one or three layers;

• The STOPAQ method. The patented visco-elastic product is applied. Manually, or by machine.

Analyzed items for the whole project are:

• Purchase cost per linear meter, the direct cost to purchase project materials;

• Man cost per linear meter;

• Time. The days to execute the total project;

• Maintenance cost, the direct cost

to coating maintenance for gas pipeline;

• Complexity of installation;

• Technical specifications.

Many technical specifications have been studied:

• Adhesion to metal and other;

• Experiences worldwide;

• Nominal thickness per layer (Mills);

• Specific electrical resistance (Ω - m2);

• Temperature of operation (C°);

• Elongation (%);

• Cathodic Disbondment 28 Days,

1.5 volt, 3% NaCl 95 C°, mmr;

• Recovery or Self healing of coating per mechanical detachment.

The outcome of the comparison shows that a low investment in

material (100% Solid method) provides high cost in manpower and maintenance. Using the FBE method will rise up investment cost when there are still high cost for maintenance and manpower.Using the STOPAQ solution will generate cost which can be compared with the FBE method. However, cost for manpower and maintenance will be considerably less.

Looking at environmental risks, complexity and technical specifications the STOPAQ solution seems to be the best solution by far.

“I don’t think it’s a secret to anyone that the trans-Alaska pipeline, the terminal at Valdez, is a critical asset not only to

the state but the country. It’s stating the obvious - that this pipeline plays a critical

role in this nation’s economy.”Eric Gonzales

The year was 1974 and Alyeska had an incredibly large problem on their hands. Their pipeline had been delayed for years as politicians argued about environmental impact studies, labor disputes and land ownership questions (and probably argued about what was in it for their constituents). At that time, Fusion Bonded Epoxy (FBE) was a somewhat ‘new on the scene’ pipe coating and manufacturers and applicators were both learning their way through some kinks.

In any case, the FBE coated pipe that had been patiently waiting in pipe yards scattered around Alaska had, unfortunately, not been coated with an FBE designed to withstand several years of UV exposure. Imagine that for a second; 380 miles of 48” OD pipe sitting in a pipe yard...and the factory applied coating is experiencing massive failures due to UV degradation. I have to believe this resulted in many sleepless night for those responsible for the integrity of that pipeline.

Since 1974, the Alaska pipeline coated by Covalence (formerly known as Raychem)

420 miles of the 800 mile Trans Alaska Pipeline are above ground.

The Dalton Highway which runs (at times) parallel to the pipeline.

Now let’s look at this same problem from another perspective; that of the somewhat fledgling technology company; Raychem Corp. The year was 1974 and Raychem had an incredibly large opportunity on their hands. Scattered across Alaska were 380 miles of 48” OD pipe, coated with failing FBE.If Raychem could engineer a solution for this incredibly difficult problem, Raychem would cement their place at the top of the heat shrinkable pipeline coatings world and leave their mark on one of the greatest pipeline projects of all time.

backing that did not yet exist; using an adhesive that did not yet exist; installed with equipment that did not yet exist and having this all completed within a time frame that did not dramatically compromise the timing of the project. Raychem’s response: “No problem.” Raychem had already been established as a leader in heat shrinkable technology and specialty adhesives. They didn’t have the perfect products already created, but they did have a solid base of proven technologies to work from. It was determined early in the process that the timeline for this

A beautiful partnership is born in 1974.

So, the problem as it stood was re-coating 380 miles of 48” pipe; in the field; faced with sub-zero temperatures; installed on top of a failing coating; using a product

project needed to be 6 months or less (keep in mind, that was 6 months to production so it would have to include training the different pipeline crews and qualifying the product).

It was also decided early in the process that the best solution was going to be a heat shrinkable, spirally wrapped tape product. Raychem had never manufactured a tape product before! So the team (led by one of the great corporate leaders of all time, Paul Cook) got to work conquering this mountain. The product which was eventually used was called Arcticlad (and was similar to another product called Rayclad that continues to be used today!).

As one team was working on developing and perfecting the Arcticlad, another team was busy engineering the machines that would clean the pipe; preheat the pipe; wrap the Arcticlad and then shrink the Arcticlad. Quite a tall order. Starting at the beginning, machinery was built that encapsulated the pipe and had numerous wire brushes working to knock any lose or disbonded FBE from the pipe.

The next step in the process was the preheating station. In order for the Arcticlad to properly bond to both the bare steel (where the FBE had disbonded) and to the still bonded FBE, the bond line temperature needed to be ~225 Fahrenheit. Quite a challenge to raise the temperature of a

48” pipe from below zero; up to 225 in a reasonable amount of time. Custom

heaters (sometimes as many as 8 or 10 used at a time) were designed for just this purpose.

Finally, the Arcticlad would be spiral wrapped using a specially engineered tape wrapping machine. The heat of the pipe (from the machines above) was sufficient to to create adhesive flow and put the Arcticlad backing into a state of crystalline melt; which

resulted in the adhesive filling, flowing and forming a homogenous layer which acted as a sealant and offered some physical protection for the pipe.

In the end, the project was successfully completed. The six month time frame was kept. Alyeska was able to salvage

and still use their pipe in spite of the damaged coating; and Raychem was

able expand their business into the oil and gas pipeline market with what turned out to be a $23 million dollar project (which would be more than $100 million in 2013 dollars!). Thirty eight years later this pipeline is STILL in service!

As an added bonus, the new technologies Raychem had created to solve this problem were able to be transitioned into entirely

new (and leading) product lines. Modern products (currently under the Covalence Seal for Life heading) including ambient temperature wrap around shrink sleeves; factory applied line coatings; closures; road bore sleeves; high temp wrap around sleeves and others can all trace their ancestry right back to the mid 1970’s.

One man’s problem is another man’s opportunity. Isn’t that a beautiful thing?

When our beloved alligator has a prey clamped its jaws, he never let’s go. His scales protect him from harsh attacks from all sides. The properties of this powerful beast are similar to the concepts of corrosion protection of Seal For Life’s Covalence Shrinkable Systems. The innovative shrink technology of Covalence protects critical infrastructural objects without losing elasticity. Covalence is one of our most powerful and proven technologies. Whether in combination with the visco-elastic corrosion prevention materials, hot-melt and masticadhesives, total care shrink technology is the way to Seal For Life tight. It’s about making the surface preparation and the applicators’ job easy. Covalence – the first and still the best at heat shrink technology.

It all began with the discovery of oil underground in the Northern Netherlands, the region whereSFL’s Technology centre is located. Actually, right between the biggest western European gas and oil field. This discovery of oil was followed in the 1960s by the discovery of a huge gas field at 20 kilometres distance from Stadskanaal, where SFL develops new technologies to support the oil and gas industry.

Half a century later, and the gas and oil industry has now built on those foundations to become a many-branched industry and network of expertise in the Northern Netherlands. And the region is also positioning itself on that basis: the Northern Netherlands is the energy region of the Netherlands and it follows from this, of course, that its full focus is on energy transition and sustainable forms of energy.Energy Valley’s solid cornerstones are Gasunie and Gasterra. These companies have helped build the basis of the Energy Valley brand, not only advancing the region’s profile in Europe but also worldwide. In

addition, the rapidly expanding port of Eemshaven is literally an open and highly accessible gateway to the world.

Factors relating to “sustainability” and energy transition have thus become important themes for this region, which explains why STOPAQ as a manufacturer of sustainable anti-corrosion systems feels so particularly at home in this consortium.

Sports namesSTOPAQ has been an active “green member” of Energy Valley since 2010. The Energy Valley Topclub affiliated to this sponsors a number of leading sports companies in Groningen in order to put the intitiatives occurring in the Northern Netherlands under

the spotlight. For example, the Gasterra Flames basketball players are also being sponsored alongside the Nic/Alfa college korfball club and the Abiant/Lycurgus volleyball club.

However, the most famous name has to be the professional football club FC Groningen for which Energy Valley Topclub has become a key sponsor. FC Groningen plays in Dutch professional football’s highest division – the Eredivisie – and has a celebrated history. The club plays each year for its place in European football and in the past has even knocked out the legendary Atlético Madrid. The association’s mission is to position itself as a green sports association with the most sustainable possible approach. As an example, its management, staff and players all drive gas-fuelled cars.

The Energy Valley Topclub has a special lounge at FC Groningen’s modern and quite splendid stadium where, prior to the start of matches, it holds regular lectures, presentations and debates on the theme of “energy”.STOPAQ takes an active part in these discussions and is consequently a proud member of the Energy Topclub.

SFL Industries is a strong contributing team player in the Energy Valley TopClub A band that seals a pipeline?

Thanks to Oppanol® – the polyisobutylene (PIB) made by manufacturer BASF – this is not just a utopian dream but has been proven in practice. Over recent years, STOPAQ has developed a band that uses Oppanol as its principal constituent.

This Oppanol constituent is a PIB, which is to say an organic compound composed of carbon atoms with excellent sealing properties. The band complies with all international requirements and has also been ISO 9001, kosher and halal certified.STOPAQ is used to protect pipelines

Even at -69 degrees Celsius it can’t be brokenagainst corrosion and hairline fractures. The surface of the pipe is made fully impermeable to outside influences and is thus fully protected. Oppanol means that pipes can operate entirely independently of climatological conditions; whether the pipe is located in the desert or in polar regions, it remains protected.

Moreover, Oppanol is non-toxic and does not constitute any danger to the environment or to people working with it. This contrasts with the current method of insulating pipes using other polymers. Traditional competitive 2-components and solvent based solution have the added disadvantage that the solvents

incorporated in the resin are released under extreme conditions, such as in the desert. Protective tents have to be erected in order to work with traditional polymers under such circumstances. These are all disadvantages that do not arise when working with SFL’s solutions based on Oppanol. For instance, SFL’s STOPAQ has powerful properties. It bonds well even on rough surfaces. Should a damage unexpectedly appear in the coating, STOPAQ’s wrappingband with an outerwrap tape or shrink sleeve, then exerts selfhealing properties to seal the damage automatically. Also at -45 degrees Celsius, although it takes 3 months.

There is also a tight bond in the working relationship between SFL’s

technology centre Stadskanaal and the manufacturer BASF. SFL has global patents and BASF supports SFL by raising awareness of the product, including among its own customer base. Moreover, BASF itself also employs SFL’s STOPAQ systems. Both companies see this healthy partnership as an integral part of their success. In addition, the customer is at the forefront: “Do it once, do it right.” Moreover, its product development based on mutual agreement continues. SFL’s proven creativity, through the deployment of Oppanol to achieve innovative Seal For Life goals, will be of foremost importance in this.

Development of the table began with Shell. The oil company needed a means of combatting corrosion on

pipelines. STOPAQ began seeking out appropriate materials and in so doing came across Oppanol.

STOPAQ now enjoys a global customer base, especially in the Near East and Middle East. That is no surprise given the huge number of pipelines close to the oil fields. STOPAQ is Saudi Arabia’s exclusive supplier of anti-corrosion agents for all pipelines running underwater, which is more than half of all the pipelines in the whole of Saudi Arabia.

STOPAQ intends expanding its activities into Russia in the near future. Moreover, its product development continues apace. STOPAQ’s proven creativity, through the deployment of Oppanol to achieve innovative goals, will be of foremost importance in this.

The Oman Gas Company is committed to achieve tech-nical excellence in terms of maintaining integrity of

its gas network. Several major integrity related projects were completed in the past or are in the verge of completion. A brief account of each project is made here by Rajdeep Dutta, former Head Integrity Management at Oman Gas Company and now Head Pipelines Maintenance Planning at Petroleum Development Oman.

Coating RehabilitationA major coating rehabilitation project has been completed on 16”, the Murayrat–Wadi Jizzi gas pipeline. The contractor was Galfar. Under this project approximately 1200 coating defect locations were excavated, verified and repaired with STOPAQ.The 20” Yibal–Al Ghubrah gas line had its original FBE coating damaged over almost its entire length. A total of 14 sections were strategically selected

SINCE 1998 AT PDO OMAN

MAOP of the pipeline restored. In 2004 a total of 126 m composite repairs were carried out, whereas in 2005 this number was just 176.5 m.

Cathodic Protection UpgradeThe contract was awarded to W.J. Towell and under this project in 2005, a total of 11 CP stations were successfully commissioned and delivered in fully functional condition. With the newly commissioned CP stations, the 16” Murayrat – Wadi Jizzi gas pipeline is 100% cathodically protected at present. Whereas in 2002 (when OGC took over its operation) only 20% of its length was properly protected. Similar success is aimed for 20” gas lines on completion of this project. This pipeline has historically suffered very low level of CP, due to system inadequacy coupled with failed external FBE coating.

Facility & Section ReplacementBuried drain vessels removal completed at the following PRTs: SIE, Shafa, Al Ghubrah, RPP/RIE, Wudam & SQU PRTs. All removed vessels were delivered to OGC Mabella yard. As recommended by in-house corrosion audit, corroded sections of the Al Ghubrah delivery line and Wadi Jizzi (train-II) piping assembly have been successfully replaced with new ones. A 300 m. section of 20” gas pipeline was exposed and displaced due to wadi washout at Bidbid area. The section was isolated and successfully replaced with a new one and the pipeline recommissioned.

By Rajdeep Duttafor continuous coating rehabilitation, where higher density of external metal loss corrosion was reported by IP. The work was carried out under maintenance contract and was completed by February 2006.

Intelligent Pigging & VerificationA major contract was awarded to Rosen to carry out high resolution MFL type intelligent pigging (IP) in all piggable OGC pipelines over a total length of 1,862 Km in 2004. The IP program was successfully completed. IP follow-up activities, e.g. dig-up verification and recoat & repair were completed. All metal loss defects reported to be more than 30% of wall thickness (WT) were excavated and verified. Automated UT was used for internal defects, whereas direct pit depth gauging was used to verify the external defects.

Pipeline Composite RepairDuring IP verification any defects reported and/or found to be more than 50% of WT were repaired with IMG composite repair system. If the safe pressure as per ASME B31.8 was calculated to be less than present MAOP of the pipeline, these defects were also repaired and the original

“Woldwide,

STOPAQ.”

Until the beginning in protecting the pipeline inside the casing against corrosion. The cathodic protection current could reach the pipeline inside the material of the casing. However, with the prohibitions against the use of asbestos cement casings, this situation changed. With newer casing materials, the industry could no longer trust that the cathodic protection would work properly. Because casings are often located in hard-to-access areas and ineffective cathodic protection gives rise to corrosion issues, it became increasingly important to treat the carrier pipe inside the casing to prevent corrosion.

Considerations for corrosion prevention of a pipeline inside a casingIf the material of the casing is not isolating, additional measures are not needed. However, despite the fact the pipe is sealed on both sides, water and/or soil almost always find their way into the casing. Frequently, this occurs with condensation which is very aggressive to steel.

If the material of the casing is not shielding the protection current and is completely filled with water, cathodic protection will do its job and no corrosion of the carrier pipe will occur. However, this is a very uncertain situation. Most of the time, the carrier pipe is not protected against corrosion.

After investigations and practical ex-pe riments, we were convinced that the Stopaq material is an excellent anti-corrosion system for our pipelines du-ring a very long period. We saw through research that the system keeps its properties for at least 35 - 40 years. With this knowledge and our experience in the

Dutch Gasunie of using wrapping bands and paste in anti-corrosion systems (in which the pipeline does not need maintenance), when we met a problem with a casing we tried to find a solution with the use of an anti-corrosion system. The only way to prevent possible future corrosion problems is to fill the annulus of the casing with an anticorrosion system material. We found that only Stopaq’s casing filler system could fulfill our demands.

Stopaq casing filler is a fluid-like liquid at a temperature of about 60ºC. So the whole annulus can be filled with Stopaq. We started with an experiment to fill one casing and this was very successful.

Properties of Stopaq anti-corrosion systemIn co-operation with Stopaq, we de-veloped a method to fill the annulus of the casing with a liquid Stopaq anticorrosion system. The Stopaq ma terial has excellent properties to adhere to every other known coating material. At 60ºC the Stopaq material is a fluid liquid. With measurements in combination with calculations it is a possible to establish if the protection of the carrier pipe is sufficient or not.

On the other hand if there is no possibi-lity anymore for easy access to the buried pipeline because new roads will be built, we must take measures to protect the integrity of the pipeline. integrity. This can be done by installing a cathodic protection system inside the casing by means of galvanic anodes. However after about 10 years the system will not deliver enough cathodic protection current. So you have to take into account that in a relatively short period, the system will have to be renewed.The renewing of the corrosion prevention and cathodic protection

systems is very difficult, especially when accessibility to the casing becomes an issue because there is a new construction built above ground. For new constructions, cleaning of the annulus is not necessary, but problems occur with the cleaning of the annulus of existing casings. With water under a certain pressure and flow the space between the carrier pipe and the casing is cleaned with water under a certain pressure and

flow. The Stopaq material adheres very intensively to the metal surface . The anti-corrosion system used for the casing in combination with the carrier pipeline will provide protection against corrosion for a very long time. The system can even be called maintenance-free. Cathodic protection is not necessary and is even not possible because the casing filler material will completely cover the metal

In the Netherlands, casings are obligatory under certain conditions. For example, pipes may not cross railways

without a casing. Plastic or certain coated casings can shield the cathodic protection current however and therefore

are not suitable for cathodic protection of steel carrier pipes and for this reason complementary measures are

necessary to protect them against corrosion. Moreover, under certain conditions there is no possibility to verify or

monitor the corrosion prevention system inside the casing once it is in place. In such cases, the construction of the

pipeline and the situation in which the pipeline is laid require specific protection measures.

surface. At this moment, casing filler can be applied all over the world. There is for example a container filled with casing filler on its way to Sakhalin to solve a corrosion problem.

TechniqueAs previously mentioned, the Stopaq mate rial has the properties to adhere to the coating materials and to flow to

ConclusionNow there is a new way for corrosion prevention of buried pipelines inside hard-to-access casings. We can describe this as an anti-corrosion system. The casing filler material stays flexible with broad temperature ranges and maintains complete coverage of the metal surface to be protected. The solution is maintenance- free after application for a very long time. Cathodic protection is not necessary and is even not possible because the material will completely cover the metal surface to be protected against corrosion. Given the Dutch Gasunie experience, today we use Stopaq anti corrosion system – the Stopaq anti-corrosion system - termed the ‘Stopaq casing filler’- inside all new casings and if necessary in existing casings.

fill holes and crevices. We did practical investigations and discovered that the liquid kept its properties after it became solid again. We filled a casing and saw that the liquid filled it completely. The temperature was raised to 60ºC and the material is then liquid and as thin as water which makes it rather easy to fill the annulus completely. After cooling of the liquid the properties did not change. The adhesion to the metal or coating of the pipe inside the casing remains the same and there is no change in the flow properties. So the pipe will be covered completely and corrosion will not occur for a very long period. The cathodic protection current mea-surements showed that the current demand decreased dramatically.

Stopaq was asked to assist with two piles which were previously coated, pre-installation, with an undefined epoxy coating still demonstrating good adhesion in dry areas above the water line. The splash zone area, however had been maintained over the years with various epoxy coatings and the piles suffered from severe corrosion in some areas. The impressed current had caused premature failure right after application (within 1 to 6 weeks) on the piles, and additional failures due to salt entrapment and cracking of the existing protection system developed over a service period of 2 to 5 years.

PropertiesThe Stopaq corrosion prevention ma te rials are fully flexible and do not require tensioned application. The materials do not harden or cure and keep their unique characteristics

throughout the lifetime of the object. The materials are impermeable to water and oxygen, two ingredients that cause corrosion, and adhere to any surface, including steel, concrete, PVC and existing coatings.

Non-sense of non-shielding coatingsSelect the right coating for moisture resistance

Pipeline coating degenerationCoating degeneration can take many different forms. The primary objective of this article is to identify the cause and mechanism of degeneration and how it can be prevented.

The importance of exploring coating degeneration to a pipeline operator is to assess the impact it has on pipeline corrosion. Furthermore, the cost and complexity of implementing a corrosion management strategy play a vital role in coping with the risks caused by the degraded coating. Active corrosion on underground pipelines can occur where the coating is defective and the corrosion process may be driven by one the following conditions:

• Ineffective CP The most common cause of ineffective CP is poor quality monitoring which fails to identify under-protection and extensive coating breakdown. This breakdown creates a total current

demand far in excess of the original CP design criteria.

• CP Shielding CP current is prevented from flowing onto the pipe steel by a high resistance barrier, such as coating that has lost adhesion to the pipe. This creates conditions in which pitting and general corrosion occurs. In anaerobic soil conditions the rate of corrosion attack may be accelerated by bacterial or microbial activity.

• External Drivers Electrical interference, stray current and galvanic effects can nullify the effect of the applied CP and create a corrosion problem where the pipe coating is defective. AC induced corrosion is most commonly associated with small coating defects.

• Stress Corrosion Cracking (SCC)Stress corrosion cracking on underground pipelines is most commonly found under a coating that has become porous or has lost adhesion. Moisture must be present at the pipe surface but the critical potential for SCC initiation and growth is less negative than the commonly accepted protection potential of – 850 mV so CP shielding is a factor in SCC. Some degree of pressure cycling is required for axial crack growth.

Pipeline coating assessmentThe criteria for judging significant coating degradation or failure may depend on the particular operating environment for a pipeline. The optimal remedy for controlling corrosion risks will depend on which of these above four conditions apply to the pipeline.

CP shielding poses particular problems because the symptoms of CP shielding cannot be measured reliably from the ground surface. Thus detecting the resulting corrosion can only be determined by intelligent pigging or direct observation. For this reason

special emphasis is placed on the degradation mechanisms that contribute to the risk of CP shielding on an operational pipeline. The approach taken in this article has been to ask the following questions:1. Can coating be applied and operated

in such a way that none of these failure modes critically impairs the integrity of the pipeline within the original design life?

2. If there is evidence that pipe coatings are showing premature failure, which measures are required for future prevention?

According to Dr. D. Norman (University of Cambridge) on

behalf of the European Pipeline Research Group (EPRG),

the external part of a pipeline has two different lines of

defense against corrosion. This corrosion can be caused

by the environment around the pipe including natural soil,

waste materials and seawater.

3. Which measures can be taken to quantify the degeneration of coatings on pipelines that are approaching, or have exceeded the original design life?

According to J. Leeds, the biggest problem of CP and Coatings is the uneasiness with pipe-to-soil potentials and lack of accurate coating survey methods. Most common methods used to monitor CP and by inference) pipe line coating conditions and corrosion, are rudimentary and subject to inaccuracies.

Pipeline coating moist resistanceThe fundamental role of a pipe line protection in the form of coating is to provide an electrical and electrochemical barrier isolating steel from corrosive soil by insulating anode and cathode areas. This brings corrosion to a halt by breaking the continuity of the electrical circuit. The fundamental component of which the coating is made, must be moisture resistant. This guards the coating against further degeneration caused by any dampness that penetrates into the steel-coating interface.

Few suppliers pay attention to long-term moisture resistance of coating. This, however, is the element that really matters. A study of protective coating data

reveals that emphasis is unfairly placed on mechanical properties and pseudo-soil effects. Moisture uptake can significantly reduce coating mechanical properties, making it much easier for soil stresses to permeate and damage the coating. Hence all mechanical properties should be related to the coating’s moisture content and all properties should be evaluated at a series of moisture contents.

A coating’s moisture resistance is reduced by holes: defects that expose steel to corrosive soil. Undermining these defects gives rise to degeneration which can be yards in length and represent a major problem for operators, particularly if the voids fill with moisture. If the voids are anaerobic and full of nutrients, they also become sites for sulfate-reducing bacterial activity with associated corrosion processes.

Pipeline coating preservation Is there no coating system that can guarantee to completely fulfill the basic requirement of separating anode and cathode areas on a steel pipe(line) from the corroding environment for its design life?

To answer this question, it is necessary to look at non cross-linked anticorrosion and adhesive materials which bond on a

molecular level to steel and PE. CP is as a supplementary technique to contain corrosion processes at coating defects if applicable as the visco-elastic systems exhibit self-healing characteristics. This feature is intrinsic, and inherent to the system. Traditionally, there are two coating-defect distributions: 1) Size, and 2) Distance. Both distributions determine how CP is apportioned on a line and determine the CP’s effectiveness at individual coating defects. This is matter most.

Coating-defect numbers vary. Generally the newer the pipeline, the fewer the defects. Defect numbers also vary with the coating system used. The coating systems showing fewest defects as the pipeline ages are FBE or extruded PE three-layer and extruded two-layer, largely related to field joints where tape or sleeves were used. The coating system showing the largest defect numbers in the shortest time is polyethylene tape or butyl adhesive where severe ruffling can occur in less than a year, but this ruffling is determined by pipe diameter and soil conditions. In dry sand such a tape system can show excellent properties and few defects after 20 years of exposure. Therefore unqualified statements can lead to unfair conclusions about coating systems.

“Stress corrosion is most commonly

found under a coating that has

become porous or has lost adhesion.”

Pipeline coating designPipeline coating is designed to prevent the corrosive elements of the backfill from directly contacting the pipe steel. A coating may be deemed to have failed if any soil or water does make contact with the pipe steel. Nevertheless, some degree of coating failure is unavoidable and CP provides a particularly cost effective solution to this problem. A low level of coating defects and a fully effective CP system is, for most operators, a common and acceptable condition for an operating pipeline.

In his outline, he sketches that the first line of defense is the external pipeline coating. The second line of defense is cathodic protection, designed to prevent corrosion at sites of damage to the coating. The long-term performance of an external pipeline coating may thus be defined as its ability to prevent active corrosion of the pipeline steel either directly or in combination with the applied Cathodic Protection (CP).


In December 2012, Anti Corrosion Technology Pty Ltd (STOPAQ B.V.’s Australian Partner) was

successful in specifying STOPAQ corrosion protective system with Australia’s largest independent

oil & gas company and one of the world’s leading producers of liquefied natural gas. The objective

was to repair a damaged jacket leg on a major LNG platform in offshore Western Australia

– where severe corrosion activity was evident on the steel substrate due to existing coating

failure. After weighing up all the advantages of STOPAQ in comparison to conventional coating

systems – such as minimal surface preparation, safe and easy scope of work and application for

the contractor, proven long–term performance as a corrosion protection system, etc. – it was

obvious that the only solution was STOPAQ’s anti–corrosion system. The STOPAQ system, which

was effectively applied to the damaged X–knot section by rope access, consisted of CZH Paste, CZH

Wrappingband, Intermediate PVC and Outerglass Shield XT. The success of this project indeed

sparked great client confidence to utilize STOPAQ for many other of their offshore (and onshore)

applications.

Pemex and the Mexican Ministry of Communications and Transport

awarded Stopaq a project to protect pipelines at Paso del Toro in Boca

del Rio, State of Veracruz. Rehabilitation was required due to the

failure of the existing coal tar coating on the 30” and 20” LP gas and

oil transport pipelines. Located in a hot and humid environment, the

surface temperature was 12-17 º Celsius so air temperatures between

27-29 º Celsius left condensation on the lines. Without shutting down

the pipe, the Stopaq coating system was successfully applied, consisting

of Stopaq Wrappingband CL, intermediate PVC (yellow) and outerwrap

PVC.

A rusted bolt is pushed into the bottom of a container filled with Stopaq material. Pressure forces Stopaq to flow underneath the entrapped air and cover the metal surface. Once covered with Stopaq it will not be replaced by air again.

Finally the entrapped air will detach from the metal surface and will move into the Stopaq material. The coverage is accelerated with temperature and the metal surface is fully covered in the course of time.
