Delivering results in tough pipeline locations.

Weatherford’s Pipeline & Specialty Services (P&SS) group had its beginnings in the pipeline precommissioning and commissioning industry. Our heritage traces back to the early 1970s when the idea of a specialist service company that was focused on providing answers to the challenging aspects of precommissioning was born. Today we are the industry’s leading global pipeline service provider of innovative and purpose-built specialty equipment.

With almost 40 years of experience in the pipeline industry, we have strived continuously for excellence in making our services available for any pipeline project in the world today. Our services include:

• Cleaning: Using chemical or mechanical methods to remove deposits or debris to ensure that the line is fit to be filled.

• Geometry inspection: From a simple gauge plate to the most sophisticated multichannel caliper.

• Baseline survey: Establishing pipeline integrity parameters through in-line inspection tools, such as the magnetic flux leakage (MFL), ultrasonic (UT) and mapping tools.

• Filling: Using forced or free-flooding methods with Engineered Chemistry® to ensure optimum test medium conditions.

• Pressure testing: Either hydraulic or pneumatic methods.

• Dewatering: Using advanced compression and dewatering train designs to leave the minimal residual water.

• Drying: Using chemicals; high-pressure air; low-pressure, high-volume air; or vacuum to achieve target dew points.

• Purging: Using our site-generated MN2™ nitrogen process to

efficiently purge the pipeline with no supply chain issues.



Innovating pipeline precommissioning and commissioning technology.

A topic extensively discussed and written about is the disappearance of “easy oil,” whereby new energy reserves are no longer onshore near major sources of infrastructure or indeed where the energy is consumed. Energy companies have to work harder to exploit these reserves in in-creasingly deep water and remote onshore locations.

To meet the challenges of precommissioning and commissioning pipe-lines in these new frontiers, Weatherford’s P&SS group relies on a core business behavior that seeks innovation.

Since its inception, Weatherford has revolutionized our industry with inno-vative technology. Because of our past experiences, we have relied on in-novation to provide the industry with the answers to some of the toughest pipeline questions—placing us at the forefront of the industry in provid-ing solutions and new technology. In the following pages, we present an overview of some of our innovative services that are deployed around the world in some of the toughest pipeline projects.

Today we can claim many industry firsts from the deepest oceans to the highest mountain passes and have completed numerous energy projects—small and large—in the hottest and coldest environments on this planet. Some of our deep-water records include:

• Subsea hydrotesting: 9,022 ft (2,750 m)

• Pipeline dewatering: 9,022 ft (2,750 m)

• Coiled-tubing pipeline filling: 5,741 ft (1,750 m)

• Surface hose deployment: 3,281 ft (1,000 m)

• Subsea precommissioning skid: 9,022 ft (2,750 m)

• Precommissioning using drill-pipe down-line: 4,331 ft (1,320 m)



Subsea precommissioning and commissioning.

Weatherford’s Denizen™ system is the world’s premier subsea pipeline commissioning system. This state-of-the-art device mounts directly to the frame of a remotely operated vehicle (ROV). The Denizen system has the capability of filtration, flooding, chemical treatment, and testing both pipelines and flowlines without intervention from the surface. All these services can be accomplished at depths of up to 9,842 ft (3,000 m) with pressure tests up to 20,305 psi (1,400 bar), while the Denizen unit logs, monitors and transmits all testing and operating data to the surface, removing the need for a large topside spread.

In addition to reducing time and topside vessel space, the Denizen system also is less susceptible to adverse weather conditions that affect traditional down-line systems and can be rigged up and ready for operations quickly.

TACS™ temporary air compression stations and services.

As pipelines are laid in deeper water, lay techniques have changed. Many require contingency against the catastrophic occurrence of a wet buckle in addition to conventional air requirements for dewatering and drying. Weatherford’s P&SS group has developed compact modular compression systems that can be tailored to suit the industry’s deepest water challenges. Because of our unequaled track record, we have retained the largestfleetofequipmentintheworld.

The fully stand-alone TACS equipment includes feed compressors, air dryers, high-pressure boosters, coalescing and carbon-bed oil-removal filters, flowmeters, centralized remote monitoring system, fuel pumping and distribution system, and all associated utilities.



Membrane nitrogen MN2SM services.

In remote locations, reducing logistics and the reliance on supply deliveries is paramount. Nitrogen is a vital tool for preserving the condition of the pipeline and ensuring safe commissioning operations when starting up any new pipeline. Our on-site generated MN2

™ equipment completely eliminates the problems associated with supplying liquid nitrogen to any location because we use the compression systems already on-site to produce nitrogen from the air that surrounds us. In addition to decreasing costs, and reducing the burdens of logistics, MN2 services also are much more environmentally friendly and CO2 efficient, because none of the electricity associated with liquid-nitrogen production is consumed and there is a huge reduction in CO2 associated with transporting cryogenic supply tanks—even at a short distance.

Pipeline geometry inspection.

Weatherford’s MultiCal™ 360 multichannel caliper tool is a new generation, advanced, in-line inspection tool that combines multichannel caliper inspection and SAAM® (smart acquisition analysis module) technologies to provide new levels of inspection capability. During precommissioning operations, the depth, width and length of dents can now be defined. This includes their position around the pipe (o’clock position) and ovalities, as well as their precise geographical location. MultiCal 360 also has special sensors for measuring bend radius providing the ability to establish as-built bend profiles without referring to construction documents.



Umbilical testing services.

Floating production systems fed by multiple subsea wells have become the industry’s response to deepwater developments and marginal field production. This response has led to an increase in the number and complexity of umbilical control lines. We meet this challenge from load-out at the manufacturing facility to the commissioning and function tests after installation at the platform or FPSO. We provide:

• Load-out monitoring

• Hydraulic flushing, chemical-line pressure and decay testing

• Electrical insulation-resistance testing via electrical time-domain reflectometry (TDR) and fiber-optic cables by optical time-domain reflectometry (OTDR)

Monitoring can be performed by direct mechanical means (gauge/ recorder) or by a wireless data acquisition system (where applicable). Fluid analysis is performed by microscopy or electronic particle counters.



Engineered Chemistry®

Throughout the history of the industry, changes in environmental conditions, regulations and new technology have kept Engineered Chemistry at the forefront of our developments. Weatherford’s in-house chemical manufacturing and research and development capabilities can customize project-specific chemical solutions to suit your needs. For example, our proprietary conditioning fluid Super Dry™ 2000 dewatering agent offers comparable hydrate suppression/drying capabilities to methanol and glycol, without the health and safety issues surrounding both of these products. The product exhibits very low toxicity, is biodegradable, and has no potential for bioaccumulation when disposed into the marine environment.

We take our environmental responsibilities very seriously; and because we manufacture as well as engineer our own chemical solutions, we can be confident that only the best products are used on our projects. For example, in the North Sea we obtained the Centre of Environment, Fish-eries, and Aquaculture Sciences CEFAS “Gold” status ranking on all our hydrotest chemicals.

Subsea leak detection.

Advances in technology have enabled us to assemble a range of passive and active acoustic tools and fluorimeters, as well as highly sensitive and accurate mass spectrometers to tackle any subsea leak-detection problem. When a hydrotest fails, traditional methods of detection can take a long time to locate accurately the problem area. With so many assets on standby, leaks can be very costly, jeopardizing project budgets. In combination our systems— irrespective of test medium, water current, visibility and even low-pressure differential conditions—can quickly find the leaks that cause hydrotests to fail.



Experienced personnel providing rapid deployment of new technology.Manufacturing and design.

Weatherford has been manufacturing precommissioning products since 1971 under the Kopp brand name in Lingen, Germany. We offer a full range of standard bi-di, cups, brushes and ancillaries, engineered and manufactured specifically for the pipeline cleaning, filling and dewatering operations. We excel at the unusual or one-off designs needed in today’s challenging environment. For example, we recently dewatered more than 312 mi (500 km) before having to cope with a 2-in. (48.2-mm) diameter change to travel up a platform riser. Our design performed flawlessly and provided for very fast and efficient vacuum drying operations to follow.

What makes our products unique and special is the fact that we are the only service company to offer in-house design and manufacturing. This capability means that the critical performance data that we collect from a precommissioning operation is fed back to the designers as they continuously improve the finished product.



Because energy is actively being exploited in very remote locations in every region of the world, it has become increasingly important to have suitable infrastructure to support projects in all locations. With more than 800 facilities in over 100 countries, there is no service company better placed geographically to support your pipeline project than Weatherford.

Successful pipeline projects have one thing in common, successful pipeline people. Weatherford has created an environment where people who are passionate about pipeline work can thrive and share ideas with each other on a global basis. We provide state-of-the-art e-learning and communication systems, enabling our employees to continue to develop their skills and share experiences with others. When you place all these opportunities in a business environment driven by excellence, the result is innovative services that are engineered to give you the most effective solution to your pipeline project
