3 Page 3 of 16 The engineers and physicists at NDT Systems & Services, leading experts in the field of ultrasonic pipeline inspection, have designed a range of intelligent tools incorporating the latest advances in nondestructive testing technology, electronic and mechanical design. The development team, including some of the most experienced professionals in the field of pipeline inspection, has created a unique design philosophy for the LineExplorer range. LineExplorer An Introduction LineExplorer UC Pipelines constitute a highly efficient and safe means to transport large quantities of oil, products or gas over large distances. Although designed, built and operated with greatest care, pipelines and their integrity are constantly under threat external and internal damage can occur. Pipelines also constitute a highly valuable asset for their owners and operators. This investment must be protected, its operation must be ensured. In-line inspection has proven itself to be an effective and efficient instrument within the overall maintenance process in securing pipeline integrity, operational efficiency and statutory compliance. Configuration LineExplorer UM Mission Tool especially configured for metal loss inspection and quantitative wall thickness measurement. It detects, sizes and locates metal loss features such as corrosion and gouging. Tool is also capable of detecting and sizing mid-wall defects such as laminations, inclusions and hydrogen-induced cracking. The LineExplorer range of in-line inspection tools designed and operated by NDT Systems & Services applies the precision of ultrasound technology in order to detect, size and locate metal loss and crack features in the pipe wall with unsurpassed accuracy and reliability. In-line inspection tools applying ultrasound technology were first introduced into the pipeline integrity market in the early1980s. Since then, dramatic improvements in the design and capabilities of electronics, processors and storage devices used as well as major developments of modern networking technologies have taken place and have been incorporated into the advanced range of LineExplorer inspection tools. LineExplorer UC Tool especially configured for crack inspection application. Detection, sizing and location of axial cracks and crack-like features such as fatigue cracks, stress corrosion cracking (SCC) or weld cracks. LineExplorer UCM Combines the inspection capabilities of LineExplorer UM and UC: special configuration unites metal loss and crack detection, available for pipeline sizes 20 and above. LineExplorer UCc Special crack configuration for the detection, sizing and location of circumferential cracks in the pipe wall or girth weld zone. LineExplorer The LineExplorer technology is also available (special configurations) in a variety of special configurations covering bi-di inspection mode, high temperature and high pressure applications. Available tool configurations 2

4 Page 4 of 16 This generation of ultrasonic in-line inspection tools is based on a modular design, covering the easy adaptation for all required pipeline diameters and incorporating the ability to perform a variety of inspection tasks using the same base module. LineExplorer tools are configured for the specific application required by the customer. Configurations include metal loss and quantitative wall thickness measurement, axial crack detection, circumferential crack detection, bi-directional mode, combined metal loss and crack inspection. In addition, special configurations are available including high temperature and high pressure options. The development of the LineExplorer tools also included scientists and engineers from the renowned Fraunhofer Group (Germany), mainly the IzfP (Institute for Non-destructive Testing, Saarbrücken) and the TEG (Technology Development Group, Stuttgart). LineExplorer tools utilize ultrasound technology for the detection and sizing of metal loss and crack features in the pipe wall in spected. Major advantages of ultrasound technology are: direct quantitative measurement, highest level of accuracy, highest level of confidence, data quality ideally suited for integrity assessment application, enhanced resolution, capable of detecting and sizing metal loss and crack features. The LineExplorer tools are available in the range of con figu rations described in the adjoining table. Further technical details are available upon request. LineExplorer: Advanced Inspection Technology The LineExplorer inspection tools provide higher inspection speeds of up to 2.4 m/s for the metal loss configuration and up to 1.5 m/s for the crack inspection configuration. All tools use solid state memory storage devices, increasing reliability and endurable temperature range. The ultrasound electronics are speed triggered ensuring that the tool will always operate at optimum axial resolution all the way up to the maximum inspection speed. A further dramatic improve ment is the realized data formatting, allowing immediate data access after an inspection run. This latter feature enables the team to view inspection results on-site and provides the possibility to iden tify any critical indications in the pipe wall shortly after the completed run. Final reports can be delivered in a range of choices in cluding printed and digi tal formats. The highly acclaimed LineExplorer PixusC software package is available for data viewing, data archiving and manage ment and a variety of integrity assess ment tasks, including run comparisons and corrosion growth assessment. Advantages Greater range: depending on the tool configuration, lines of several hundred kilometers can be inspected in a single run with full circumferential coverage. New tool and sensor carrier designs result in shorter tool length: less need to modify existing launchers and receivers. New electronics enable higher gain: improved data quality, less susceptibility to deposits, debris or wax in the line. New sensor carrier design: improved data quality in bends and better bypass flushing to ensure clean probes during survey. Powerful electronics enable combined metal loss and crack inspection.

It is of greatest importance to be able to measure the actual remaining wall present in order to assess its remaining strength and thereby the maximum allowable safe operating pressure. Flaws and anomalies in the pipe wall can grow from the outside, the inside or even from within. They can first appear during manufacturing and construction or later during the operational life of the pipeline. The environment of the pipeline, the medium transported, the type and state of any coating, the effectiveness of the cathodic protection as well as the operational parameters all play an important role regarding the integrity of a given single line or pipeline system. The operating principle of the ultrasonic inspection tool is based upon the measurement of the time-of-flight of ultrasonic signals reflected from the internal and external surfaces of the pipe wall. On the basis of the known sound velocity of the ultrasound in the coupling medium (e.g. oil) and in the pipeline wall (e.g. steel), the time-of-flight of the first reflected signal (t 1 ) is transformed into the distance between sensor and internal surface of the pipe wall (stand-off). Starting at this point, the time-of-flight of the second reflec t- ed signal (t 2 ) is used to determine the wall thickness (see Figure 2). 4

All tools are made up of pressure vessels housing power supply, electronics and recording devices and a trailing sensor carrier. The individual modules of the tool train are linked by universal joints which have been designed to enable the tool to negotiate all bend geometries typically found in a pipeline. The sensor carrier is for all sizes equipped with a sufficient number of sensors to ensure 100 % coverage of the pipe wall. The sensors are connected to the pressure-tight data/electronics vessel. This vessel houses the ultrasonic electronics and the data acquisition electronics as well as the data storage devices. The capacity is adequate to store inspection data for long sections of pipeline, up to several hundred kilometers. Furthermore, the data/ electronics vessel contains the auxiliary electronics such as pendulum, temperature and pressure measurement. The battery vessel accommodates the power supply for the tool. Depending on the power consumption, based on the length of line to be inspected and average inspection velocity, one or more battery vessels can be used. Opposite you will find an overview of standard tool specifications as well as a table of defect specifications for the metal loss configuration of the LineExplorer. Further technical information can be supplied upon request.

Different types of cracks can be detected, for instance fatigue cracks due to an applied cyclic loading or stress corrosion cracking (SCC) due to a corrosive environment, critical stress and susceptible material. Cracks and crack-like features can appear during manufacturing of the pipe, construction of the pipeline or during operational life. Irrespective of its origin, it is of great importance to detect and locate a crack before it can grow to reach a material-specific critical size after which the pipeline will fail. True crack inspection tools, such as the LineExplorer UC range, provide an effective means to detect, size and locate cracks in the pipe wall or the weld zone. The standard configuration of the LineExplorer UC is primarily designed for cracks orientated in an axial direction (along the pipe axis). These are generally the most critical crack geometries, as they are orientated at right angles to the acting hoop stresses. A special configuration of the tool, LineExplorer UCc, is also available specifically designed for the detection, sizing and location of cracks orientated around the circumference of the pipe. Typical examples of such cracks would affect the girth weld. The LineExplorer UC operates in a liquid environ ment such as crude oil or product pipelines. The liquid serves as the coupling medium for the ultrasonic pulses. The tools can also be used in a gas pipeline, by applying a suitable liquid batch. 6

Due to its reliability and accuracy, this technique is well known in non-destructive testing as a standard technique of ultrasonic crack inspection. The principle used is illustrated in Figure 3. The sensor carrier is equipped with a sufficient number of transducers to ensure that the pipe wall is covered 100 % during inspection. For the 24 tool, for example, this results in the use of 360 crack detection sensors plus an additional 24 sensors used for determining the actual wall thickness, a value needed for the data evaluation process.

9 Page 9 of 16 Special sensor carrier for pitting inspection Special Configurations LineExplorer UCM Inspection tool ready for launch Liquid and Gas Environment The LineExplorer range of tools is designed to operate in a liquid environment and is therefore ideally suited for the inspection of crude oil, product, water injection or water lines. However, if there is a need for highly accurate quality data often needed for integrity assessment or fitness-for-purpose investigations, ultrasonic tools can also be applied in a gas pipeline. In this case the LineExplorer tool would need to be run in a liquid batch as shown in Figure 4. Weld Inspection The LineExplorer range of tools is also well suited for the detection and sizing of anomalies and flaws in the weld and heat affected zone. Typical detectable flaws are: pipe misalignment, porosity, lack of fusion, lack of penetration, shrinkage cracks, undercut caps or roots and hook cracks. Special configurations of the LineExplorer tools are optionally available for all inspection tasks, including high pressure, high temperature and bi-directional operations. The opposite table introduces the configurations currently available. Further special application configurations are being developed continuously. Please contact us for further information. 8

11 Page 11 of 16 Reporting Display of coating flaws The major purpose of performing a pipeline inspection is to obtain good quality data regarding any flaws and anomalies present in the pipe wall. Accurate, reliable and reproducible data is required for integrity assessment or fitness-for-purpose studies. Information on remaining wall thicknesses, flaw geometries and topologies, corrosion growth and numerous other factors are essential in order to optimize strategies on maintenance, possible repair and opera - t ions. Inspection data from in-line inspections is a key element in understanding the integrity of a given line. The full picture, however, will also include information collected during external surveys, considering material and operational parameters, reviewing pipeline protection measures. NDT Systems & Services will document the features found during an inspection in an Inspection Report. Each report is indi vid ually prepared according to the requirements set by the customer and will include full feature lists. The exact content will be con fig ured according to the needs and wants of the customer. Alternatively different reporting packages and standardized options can be chosen. Reports are available in printed or digitized versions. Inspection data is available in a large variety of digital formats including Office, database and GIS formats. As an option, NDT Systems & Services also offer different software packages which cover applications ranging from inspection data visualization, inspection and pipeline data management, integrity assessment and run comparison to full GIS functionality. A typical Inspection Report will include an Executive Summary on the inspection and its findings. The operational details as well as the inspection results obtained and analysed will be documented. The report will include a list of Reported Features which encompasses all relevant features. This is followed by a list of Detailed Feature Descriptions including further information on a pre-defined set of features, depending on customer requirements. The report also includes information regarding marker points and a pipe tally based on odometer values obtained during the run. Further parts of the document include information regarding tool and defect specifications of the LineExplorer configuration used, data evalu a- tion procedures, defect assessment and general notes on the ultrasonic inspection technology applied. A sample copy of a typical Inspection Report is available upon request. Note: as each Inspection Report is prepared individually, the sample report can only show the general layout of a report. NDT Systems & Services also offer a full range of integrity assessment services based on the data obtained through the LineExplorer range of tools.

15 GE Energy Oil & Gas Page 15 of 16 MagneScan Triax provides greater insight into pipeline defects When MagneScan was introduced to the pipeline industry, its advanced Magnetic Flux Leakage (MFL) technology set the standard for reliable metal-loss inspection. Now equipped with Triax sensors and a number of other innovations, MagneScan is again setting new standards. Triax can read MFL signals on three separate axes (versus one or two with traditional MFL tools), enabling detection of general and axial defects from the same inspection data. This can eliminate the need to launch separate tools for each class of defects increasing your data utility and decreasing your overall inspection costs. The Triax electronics are housed in one of GE Energy s new light-weight, miniature sensor heads. This versatile adaptation allows Triax to run on board every size of MagneScan tool, from 12 in diameter upwards. It also means that the Triax module can be quickly and easily transported for a pipeline inspection anywhere in the world. One tool for general corrosion and long axial defects Triax has the ability to identify the linkage between individual pitting and the formation of NAEC. It is therefore ideal where long axial defects are a potential problem. Its improved sizing performance also makes it well suited to critical pipelines with major corrosion problems, lines with high consequences of failure and those that are likely to suffer from axial defects. When you need higher performance Triax provides pipeline operators with advanced inspection performance that goes beyond what is currently available in the industry s standard MFL tools. It offers improved length and width sizing capability at a higher level of confidence so you get a more precise picture of your pipeline s condition. As a result, your integrity maintenance plans can be optimized by reducing conservatism at the defect assessment stage. Triax can also operate in combination with one of GE Energy s new embedded Inertial Mapping Units (IMU) effectively making MagneScan Triax a 3-in-1 inspection tool. IMU gives the most precise depiction of pipeline route and profile and enables defect location accuracy of ±1.5 m. Triax delivers superior inspection specification. Its electronics and harnessing are water-protected, while Hall and velocity sensors enable it to run down to zero product speed, offering pipeline operators more flexibility. Triax provides higher confidence levels and more accurate defect data, making it possible for you to better identify the most critical anomalies and undertake fewer costly repairs.
