The article is devoted to the effective analysis of trench and trenchless pipeline laying technologies. In the course of the work, an analytical review of pipeline assembly was performed, the main technological parameters, the scope of each method, and their advantages and disadvantages were determined. List of considered pipeline laying methods: trenching, horizontal directional drilling, mechanical puncture, hydraulic puncture, microtunneling and punching. The article analyzes the classical trench method and the most widely used trenchless ones: horizontal directional drilling; mechanical puncture; hydraulic puncture; microtunneling; punching. Each of these methods has several advantages and disadvantages. The choice of the optimal method of laying the pipeline depends on many factors: the physical and mechanical properties of soils and hydrogeological conditions, the length and diameter of the pipeline, the presence of other communications, buildings and structures, as well as the budget that customers have. Work time is the last deciding factor. Based on the results of the analysis of pipeline laying technologies and expert survey of construction industry experts, the cost table of each method was compiled, outlining the main characteristics of the technology: length of pipeline, speed of work, scope, cost, and the advantages and disadvantages of each of the considered methods. The conclusions about the use of each of the pipeline laying methods were made. Each of the methods has its advantages and disadvantages, so to choose the method of work it is necessary to conduct a comprehensive assessment of technological parameters, cost, scope and timing of work. The cost of lay-ing the pipeline consists of the following factors: conducting research; selection of diameter and determination of pipeline length; choice of laying method and equipment necessary for the works; selection of equipment, shut-off and control equipment and other materials arranged on the pipeline; terms of performance of works. Taking into account these factors, an estimate is made, which determines the cost of installation of a particular pipeline. After the analysis, we can conclude that among the methods of trenchless laying of pipelines can be identi-fied horizontally directional drilling, it is this method of laying the pipeline will be appropriate to use for our region. The drilling technique allows to carry out pipelines under obstacles, to pull long segments of networks, to repair site damage. This method is universal and can be used in almost any environment. Keywords: trenches, horizontal directional drilling, mechanical puncture, hydraulic piercing, microtunnelling, punching, pipeline.

Abstract The article deals with the design of trenchless technologies for the restoration of pipelines in oil and gas engineering, taking into account the state of existing pipelines, the need for installing polyethylene pipes, and their strength and hydraulic parameters. Taking into account the high cost and timing of pipeline construction by the open method, the annual rate of aging of pipeline systems, the issue of construction, reconstruction and replacement of emergency pipelines can be solved only by using trenchless technologies, which will reduce direct and indirect financial and time costs. The term “trenchless technologies” can be defined as any method of trenchless installation and restoration of a pipeline with a description of the regulated sequence of operations performed using special equipment, instruments, materials, and human resources. Along with efficiency and cost-effectiveness, the trenchless technologies do not to deteriorate the existing environmental situation

As special equipment, long-distance pipeline is widely used in petroleum, chemistry and other fields. However, with the extension of its running time, some problems have arisen with parts of the pipeline. The detection and repair technology is the foundation for assurance of the safe operation of pipelines; therefore, in order to avoid or reduce pipeline accidents as well as to protect people's lives and property safety, periodic detection and designed reasonable repair of the pipeline has naturally become an important part of pipeline industry today. Several commonly used inspection techniques of pipeline were introduced in this paper and related repair measures were described in view of problems emerging during the service life of long-distance pipeline in the practical engineering.

Full textAbstract:
The gas pipelines usually undergo complicated and changeable regional environment. As the level of the potential difference or pipeline’s route changes in the space and therefore elastic bending cannot meet the needs when pipe changes its direction, we generally use pipe bend to connect two pipelines with different spatial extend direction during the pipe laying period, and it can reduce the temperature stress. Unreasonable design of elbow will lead to pipeline damage. We established mountain area pipeline model, and conducted analysis on pipeline stress under different elbow angles. Research shows that different angles of the bends suffer different operation stress, and we have come to the conclusion that the angle of pipe bends should not be within the range of 15 degrees to 35 degrees.

Full textAbstract:
The principal water supply and distribution systems of the World Heritage site of Petra in Jordan were analyzed to bring forward water engineering details not previously known in the archaeological literature. The three main water supply pipeline systems sourced by springs and reservoirs (the Siq, Ain Braq, and Wadi Mataha pipeline systems) were analyzed for their different pipeline design philosophies that reflect different geophysical landscape challenges to provide water supplies to different parts of urban Petra. The Siq pipeline system’s unique technical design reflects use of partial flow in consecutives sections of the main pipeline to support partial critical flow in each section that reduce pipeline leakage and produce the maximum flow rate the Siq pipeline can transport. An Ain Braq pipeline branch demonstrated a new hydraulic engineering discovery not previously reported in the literature in the form of an offshoot pipeline segment leading to a water collection basin adjacent to and connected to the main water supply line. This design eliminates upstream water surges arising from downstream flow instabilities in the two steep pipelines leading to a residential sector of Petra. The Wadi Mataha pipeline system is constructed at the critical angle to support the maximum flow rate from a reservoir. The analyses presented for these water supply and distribution systems brought forward aspects of the Petra urban water supply system not previously known, revising our understanding of Nabataean water engineers’ engineering knowledge.

Full textAbstract:
Available analytical methodologies for the stress analysis of buried pipelines against large permanent ground displacements (PGDs) apply only to straight pipeline segments. Hence, a new methodology is proposed herein for the analytical computation of pipeline strains in bends of arbitrary angle and radius of curvature, located outside the PGD high-curvature zone, but within the pipeline’s unanchored length. The methodology is based on the equivalent-linear analysis of the bend, assuming that it will perform as an elastic arched beam subjected to uniformly distributed ultimate axial and transverse horizontal soil reactions. The end of the bend towards the PGD zone is subjected to an axial displacement, calculated on the basis of overall displacement compatibility along the pipeline, while the other end is restrained by the unanchored pipeline segment beyond the bend. Using this approach, the maximum axial force at the vicinity of the PGD zone can also be calculated and consequently used for the estimation of corresponding pipeline strains with any of the available numerical or analytical methodologies for straight pipeline segments. Parametric nonlinear finite element analyses are performed to verify the analytical methodology and also derive conclusions of practical interest regarding the effect of bends on pipeline design.

Under the effect of geologic hazard, soil horizon under gas pipeline tends to subside or runoff, which may result in pipeline hanging in the air with uneven distribution of stress and consequently lead to pipe failure. In view of pipeline suspension resulted from geologic hazard and taking pipeline XX as example, software CAESAR II is used to analyze the stress of suspended pipelines with different length combined with practical and existing analysis calculation model. The critical length of suspended pipeline is obtained on the basis of the software analysis. The results with certain engineering value can provide reliable theoretical basis for practical engineering.

Full textAbstract:
The lifetime management of different engineering structures and structural elements is one of the important technical-economic problems nowadays. On the one hand, the aim of our research work is to develop an integrity management plan for pipelines and pipeline systems, and afterwards a Pipeline Integrity Management System. Material databases play important role both on the integrity management and on the engineering critical assessment of the pipeline systems. On the other hand, the aim of our research work is to establish the Pipeline Integrity Management System with different data, frequently with experimental data. The direct purpose of the paper is to present the role of the external and internal reinforcing on the structural integrity of industrial and transporting steel pipelines, based on own examinations. External and internal reinforcement was developed using carbon fibre and glass fibre polymer matrix composites, respectively. Fatigue and burst tests were performed on pipeline sections containing natural and artificial metal loss defects, and girth welds including weld defects. Both unreinforced and reinforced pipeline sections were examined. The burst pressures belonging to the unreinforced and the reinforced pipelines, and belonging to the passed and not passed girth welds were compared.

Full textAbstract:
The buckling analysis of an offshore pipeline refers to the analysis of temperature-induced uplift and lateral buckling of pipelines by analytical, numerical, and experimental means. Thus, the current study discusses different research performed on thermal pipe-buckling and the different factors affecting the pipeline’s buckling behaviour. The current study consists of the dependency of the pipe-buckling direction on the seabed features and burial condition; the pre-buckling and post-buckling load-displacement behaviour of the pipeline; the effect of soil weight, burial depth, axial resistance, imperfection amplitude, temperature difference, interface tensile capacity, and diameter-to-thickness ratio on the uplift and lateral resistance; and the failure mechanism of the pipeline. Moreover, the effect of external hydrostatic pressure, bending moment, initial imperfection, sectional rigidity, and diameter-to-thickness ratio of the pipeline on collapse load of the pipeline during buckling were also included in the study. This work highlights the existing knowledge on the topic along with the main findings performed up to recent research. In addition, the reference literature on the topic is given and analysed to contribute to a broad perspective on buckling analysis of offshore pipelines. This work provides a starting point to identify further innovation and development guidelines for professionals and researchers dealing with offshore pipelines, which are key infrastructures for numerous maritime applications.

This thesis proposes the use of an Advanced Engineering Geographical Information System (AEGIS) for the improved design of onshore pipelines, from concept to operation. The system is novel in that it is function rather than discipline or software specific. The thesis statement has been developed, and an aim and set of research objectives identified (along with the success criteria for the evaluation of the system), based on a review of current pipeline design methods. Drawing on a design science research methodology (DSRM), the thesis proposes the development of the system as an artefact in order to validate the proposed constructs, models, methods and implementations. The thesis discusses the underlying issues of data interoperability, the application of open data standards, and the integration of computer aided design (CAD) and geographical information systems (GIS). These challenges are addressed in the thesis and demonstrated through the implementation of the system. To support the development of the system, research was undertaken in the fields of pipeline engineering, environmental engineering and engineering design. As part of this research, a number of peer-reviewed journal papers were published, and conference papers presented in Kampala, Houston, London and Split. These papers covered the key fields contained in the thesis including, fluid mechanics, bio-systems engineering, environmental engineering, CAD/GIS integration (CGI), and the application and development of geospatial pipeline data models. The thesis concludes that the approach is valid, offering significant improvement across all fields compared to the current method of pipeline design. By taking a functional approach to the challenges of the design of pipelines, a system has been developed that addresses the requirements of the pipeline engineer, environmental engineer and engineering designer. The system enables the user to select the software of their choice, thereby reducing the problems associated with data interoperability, retraining and system integration. The sharing of data and outputs from analysis carried out within the system, provides an integrated approach, which can subsequently be used for the integrity management of the pipeline during the operational phase of the project. The scope for further development of this approach to pipeline design is also discussed. In addition to the inclusion of further engineering and environmental analysis, there is the potential for using the system for the design of subsea pipelines.

Full textAbstract:
When developing applications in Direct3D today, developers can choose between using the fixed function pipeline and the programmable pipeline. The programmable pipeline is more flexible than the fixed function pipeline, but what is the price for high flexibility? Is high flexibility desired at any cost? How is the choice of pipeline affecting performance? The purpose of this master thesis is to evaluate the performance of the two pipelines. This will be achieved by developing a benchmark program, which measures performance when various graphical effects are tested. The results of the evaluation will hopefully help developers to decide which pipeline to use, in terms of performance. In the end we will see that the fixed function pipeline is faster than the programmable pipeline in all our tests.

In order to provide a reliable corrosion detection system for the Trans-Alaska Pipeline System (TAPS), a distributed wireless self-powered sensor array is needed to monitor the entire length of the pipeline at all times. Such a sensor faces two primary challenges: a method to provide power for the sensor, and a method to detect corrosion. This project has two goals: to build a model of the TAPS as a test bed for a piezoelectric micro power generator (PMPG), and to use the model to explore corrosion detection methods (perhaps by analyzing changes in the vibration spectrum), for use in the sensor array. To miniaturize the TAPS while maintaining its vibration spectrum, we will specify the dimensions of the model to have the same natural frequency, turbulent flow, and vortex induced vibrations as the actual pipeline. The model will serve as a test bed for various PMPG designs, and also serve as a starting point for exploring methods to detect corrosion in pipes. The primary vibration mode was found to be due to the natural frequency of the pipe, which was 20.2 Hz for the TAPS. Experimentally, we found the frequency to be in a range from 12-19 Hz. PMPG devices for use in the TAPS should be tuned to this frequency range.

Pipelines are used around the world to transport raw materials, waste products, and, critically, potable water. Protecting the pipes from the elements often leaves them difficult to inspect for leaks and corrosion, which can cause costly, even deadly, damage. Currently, typical inspection methods are costly, interrupt service, and have highly limited inspection range. This thesis details the continuing development of a robotic platform capable of actively maneuvering inside an in-service, potable-water pipe, for the purpose of providing continuous, autonomous, long-range inspection of a pipe network. Complete inspection of municipal water pipelines requires a compact robot capable of maneuvering junctions around 100mm in diameter, with flows that can exceed 1m/s. This work focuses on several additions to prior work at the Massachusetts Institute of Technology, which developed a hull and planar propulsion system. The addition of ailerons allows full 3-dimensional control of the robot. A custom-built, wireless embedded controller runs a customized real-time OS to provide closed-loop control, as well as data-logging and remote access. A generic task architecture is designed to simplify the addition of real-time software modules.

3D printing hardware is rapidly scaling up to output continuous mixtures of multiple materials at increasing resolution over ever larger print volumes. This poses an enormous computational challenge: large high-resolution prints comprise trillions of voxels and petabytes of data and simply modeling and describing the input with spatially-varying material mixtures at this scale is challenging. Existing 3D printing software is insufficient; in particular, most software is designed to support only a few million primitives, with discrete material choices per object. In this body of work I present OpenFab, a programmable pipeline for synthesizing multi-material 3D printed objects that is inspired by RenderMan and modern GPU pipelines. The pipeline supports procedural evaluation of geometric detail and material composition by using shader-like fablets. The pipeline allows models to be specified easily and efficiently. Additionally, I describe a streaming architecture for implementing OpenFab; only a small fraction of the final volume is stored in memory and output is fed to the printer with little startup delay. I demonstrate the OpenFab pipeline and programming model on a variety of multi-material objects.

Kruisbrink, A. C. H. "The dynamic behaviour of check valves in pipeline systems." Thesis, City University London, 1996. http://openaccess.city.ac.uk/8269/.
Full textAbstract:
A semi-empirical method is developed to describe the dynamic behaviour of check valves in pipeline systems. The method is based on parameterized valve models and dimensionless valve characteristics, which may be obtained from experiments. The check valve is considered as a black box with certain input and output characteristics. The check valve closure and associated pressure surges are the dominant phenomena. Undamped check valves may be considered as a special case of damped check valves. Much attention is paid to the description of the hydrodynamic (fluid) forces on the internal, moving valve elements. These elements may be considered as translating or rotating bodies with (at least) one plane of symmetry. The equations of motion for the constrained, unsteady motion of such a body in an unconfined, unsteady fluid flow are based on the dynamical theory of Kirchhoff, extended to an unsteady fluid flow. The equivalent equations for a body in a confined fluid are based on Lagrange's method of generalized coordinates. A general (dimensionless) valve equation of motion is developed, which is valid for most of the existing check valve types. Basic differential equations are derived for the transient flow in a pipe with constant initial flow deceleration. The equations are applied to describe the check valve closure under reflection free and reflecting boundary conditions in the form of dimensionless, analytical equations. The theory is based on conventional waterhammer theory. The pipe and valve equations are coupled via the integral form of the momentum equation. The uncoupled and coupled, (dimensionless) pipe and valve equations show formally which (dimensionless) variables and valve, system and fluid parameters are relevant to the dynamic behaviour of check valves in pipeline systems. In that sense they are used in a dimensional analysis to develop (dimensionless) valve characteristics and dynamic scale laws. Based on the dimensionless valve characteristics, models for undamped and damped check valves are developed and implemented in the waterhammer computer code CVWP (Check Valve Waterhammer Program). Experiments are performed in the test facility at Delft Hydraulics to measure several valve characteristics of weakly and strongly damped check valves. The dynamic scale laws are validated by means of numerical simulations. The valve models are validated against experimental data. The study has been performed within the Check Valve Research Project (CVRP).

Lavasani, Seyed Mohammadreza Miri. "Advanced quantitative risk assessment of offshore gas pipeline systems." Thesis, Liverpool John Moores University, 2010. http://researchonline.ljmu.ac.uk/5976/.
Full textAbstract:
This research has reviewed the current status of offshore and marine safety. The major problems identified in the research are associated with risk modelling under circumstances where the lack of data or high level of uncertainty exists. This PhD research adopts an object-oriented approach, a natural and straightforward mechanism of organising information of the real world systems, to represent the Offshore Gas Supply Systems (OGSSs) at both the component and system levels. Then based on the object-oriented approach, frameworks of aggregative risk assessment and fault tree analysis are developed. Aggregative risk assessment is to evaluate the risk levels of components, subsystems, and the overall OGSS. Fault trees are then used to represent the cause-effect relationships for a specific risk in the system. Use of these two assessment frameworks can help decision makers to obtain comprehensive view of risks in the OGSS. In order to quantitatively evaluate the framework of aggregative risk, this thesis uses a fuzzy aggregative risk assessment method to determine the risk levels associated with components, subsystems, and the overall OGSS. The fuzzy aggregative risk assessment method is tailored to quantify the risk levels of components, subsystems, and the OGSS. The proposed method is able to identify the most critical subsystem in the OGSS. As soon as, the most critical subsystem is identified, Fuzzy Fault Tree Analysis (FFTA) is employed to quantitatively evaluate the cause-effect relationships for specific undesired event. These results can help risk analysts to select Risk Control Options (RCOs) for mitigating risks in an OGSS. It is not financially possible to employ all the selected RCOs. Therefore, it is necessary to rank and select the best RCO. A decision making method using the Fuzzy TOPSIS (FTOPSIS) is proposed to demonstrate the selection of the best RCOs to control the existing risks in the system. The developed models and frameworks can be integrated to formulate a platform which enables to facilitate risk assessment and safety management of OGSSs without jeopardising the efficiency of OGSSs operations in various situations where traditional risk assessment and safety management techniques cannot be effectively applied.

By investigating neural connections, neuroscientists try to understand the brain and reconstruct its connectome. Automated connectome reconstruction from high resolution electron miscroscopy is a challenging problem, as all neurons and synapses in a volume have to be detected. A mm3 of a high-resolution brain tissue takes roughly a petabyte of space that the state-of-the-art pipelines are unable to process to date. A high-performance, fully automated image processing pipeline is proposed. Using a combination of image processing and machine learning algorithms (convolutional neural networks and random forests), the pipeline constructs a 3-dimensional connectome from 2-dimensional cross-sections of a mammal's brain. The proposed system achieves a low error rate (comparable with the state-of-the-art) and is capable of processing volumes of 100's of gigabytes in size. The main contributions of this thesis are multiple algorithmic techniques for 2- dimensional pixel classification of varying accuracy and speed trade-off, as well as a fast object segmentation algorithm. The majority of the system is parallelized for multi-core machines, and with minor additional modification is expected to work in a distributed setting.

Full textAbstract:
The pipeline infrastructure throughout Western Canada is extensive, with more than 350,000 km in Alberta alone. As the profitability of oil and gas production swings, so too does the utilization of the pipeline infrastructure. During the 1990’s, the economics of some oil and gas production was marginal and the associated pipelines were under utilized. In particular, upstream producers deactivated several under utilized pipelines. Deactivated lines were blocked in, others purged and isolated, while others were completely abandoned. The profitability of oil and gas production has improved steadily since 1999 and the industry has pursued the reactivation of many of these pipelines. In several cases, the diligence of the pipeline operator during economically tight periods was less than desirable with respect to both of these functions. Poor economics also impaired the development and preservation of good pipeline design and maintenance records. The retention of the existing records was further impaired by the numerous corporate divestments and acquisitions that occurred over the past fifteen years. The lack of good quality pipeline records has hampered efforts to reactivate many pipelines. Another feature of our economic environment is the production of alternate zones from an existing well that was previously uneconomic. These zones often produce fluids significantly different than the original well completion and may not be consistent with the design of the original pipeline. This requires re-engineering of the pipeline for the new service. The most common situation is changing from one substance to another, however, changing the maximum operating pressure, changing the design temperature or changing the flow direction may also be required. The objective of this paper is to describe some of the specific challenges in reactivating dormant pipelines and re-engineering pipelines for new service conditions. The focus of this paper will be with respect to pipelines built to CSA Z183, Z184 or Z662 standards and the Alberta Pipeline Regulation.

Full textAbstract:
As a well-known means for pumping crude oil with high pour point, the economic effect of a hot oil pipeline to be built will depend on such factors as pipeline capacity, pipeline length, properties of the oil to be pumped, environmental conditions along the right of way, design scheme and operation scenarios. Generally speaking, engineering-economic characteristics of oil and gas pipelines are a complete set of the economic relationships relevant to engineering factors of the pipelines, each relationship involving at least an economic index or parameter. The engineering-economic characteristics of hot oil pipelines reflect basic regularities governing the general economic effect and each economic index of the pipelines, so it is helpful understanding these characteristics for the decision-making about whether and how to build a hot oil pipeline. In some cases, for a specific hot oil pipeline project, a decision or judgment on macro level may be made only from some common engineering-economic characteristics of hot oil pipelines, without the need for the engineering design and the economic analysis of the project in detail. The frame of engineering-economic characteristics of oil and gas pipelines is outlined in this paper, and some key elements are discussed on the basis of a large amount of engineering calculation and economic analysis of virtual hot oil pipeline projects, including the optimal pipe diameter and the optimal flow velocity for a given pipeline capacity, the economic capacity limits and the economic flow velocity limits for a given pipe diameter, the economically feasible maximum pipeline length for a given pipeline capacity, and the economically feasible minimum pipeline capacity for a given pipeline length. Though the basic economic data used in our research come from China, its research results and conclusions on engineering-economic characteristics of hot oil pipelines also would be helpful for hot oil pipeline projects in other countries all over the world.

Full textAbstract:
Pipeline repairs at large water depths represent challenges for both for mechanical repair systems and for welding systems. This paper presents the main results from a Joint Industry Project (JIP) launched in late 2005 that was focused on the following main topics: • Revision of the Recommended Practice for “Mechanical pipeline couplings” [2] in order to include requirements for clamp repairs, hot-tapping and the pipeline’s response to isolation plug forces. • Methods to qualify remotely operated subsea hyperbaric welding in a dry habitat without performing NDT. At present such welding technology is being developed to join pipelines though the use of a sleeve and two fillet welds, and for the seal welds of hot-tapping pipeline branches.

Full textAbstract:
Pipeline transportation of carbon dioxide (CO2) dates back to the early 1970’s with the construction of the Canyon Reef Carriers & Val Verde pipeline in Texas USA. Since that time about 7200 kilometers of CO2 pipeline have been built in North America (mostly in the USA), some in Asia (Turkey) and Africa and one offshore Europe. The experience of such pipelines is predominantly for the transportation of naturally occurring and relatively pure CO2 for the purpose of enhanced oil recovery (EOR).

Full textAbstract:
Operating pipelines may contain crack-like flaws created during fabrication or induced by service. Stress-corrosion cracking (SCC) and fatigue are two common mechanisms that cause cracks to develop in operating pipelines. Engineering fracture mechanics models are typically used to assess the potential for crack-like flaws to result in pipeline failure. To this end, an inelastic fracture mechanics model was developed and incorporated into the CorLAS™ computer program that is used by many pipeline operators. This paper reviews and documents the details of the fracture mechanics model. It provides the equations used to compute the parameters in the model and discusses their engineering basis. Correlations of predictions made using the model with the results of tests and pipeline failures are presented. Typical applications of the model are also reviewed. Finally, areas of possible improvements are discussed.

Full textAbstract:
Abstract Onshore pipelines are usually designed and constructed for burial conditions. However, pipeline exposures can develop from environmental and geohazard conditions such as creek crossing, soil washout due to significant rainfall events, short-term flooding, etc. Engineering assessment of the exposed pipeline sections is a vital consideration to assess the fitness of the exposed pipeline sections for continued service. A fitness for service engineering assessment methodology that was successfully used for the assessment of an NPS 10 onshore natural gas pipeline exposure is presented herein. The assessment is based on finite element analysis to evaluate several damage mechanisms, e.g., lateral and vertical longitudinal bending stresses and strains, buoyancy, hydrodynamic forces, vortex-induced vibration, mechanical damages due to foreign objects impact, and brittle fracture assessment as per failure assessment diagram approach. The proposed framework for the fitness for service engineering assessment of exposed pipe sections presented in this study helps identify potential integrity concerns and prioritize required corrective actions. The proposed methodology offers a robust framework that can significantly improve the operation and maintenance of the existing buried pipelines.

Full textAbstract:
Long distance pipelines are actively pursued by the industry to transport natural gas from remote arctic regions to markets. A chilled gas pipeline is one of the options to minimize the environmental impact resulting from operation of such pipelines. When a chilled gas pipeline crosses discontinuous permafrost areas, differential frost heave can occur. The result is pipe being subjected to potentially high strains, primarily in the axial direction. Reliable prediction of strain demands is one of the key components for a strain-based design process and it is essential for both ensuring pipeline integrity and facilitating life-cycle cost optimization for the design and maintenance of pipelines. The prediction of strain demands resulting from frost heave of chilled gas pipelines involves three fundamental engineering analysis processes. They are gas hydraulic analysis, geothermal analysis and pipeline structural analysis. Not only are these three processes complex, they are also mutually interdependent. To reliably predict strain demands and fully capture the interactions among these processes, TransCanada Pipelines Ltd. (TransCanada) and its partners developed an integrated engineering model on the basis of three well established programs for the three individual engineering processes. This paper will briefly review the integrated model for strain demand prediction.

Full textAbstract:
Establishing pipeline integrity requires an understanding of the specific threats, their relationship to the overall condition of the pipeline, and the mitigating measures required to assure safe operation. In the past, the pipeline industry relied on years of research and experience to develop a set of tools to analyze these threats and apply conservative solutions to ensure pipeline integrity. With the implementation of the Integrity Management Program (IMP) in 2004 by the Pipeline and Hazardous Material Safety Administration (PHMSA), pipeline integrity must be addressed by operators where the analysis methods and results must be documented and defendable. This paper presents a detailed discussion of how existing knowledge, advances in analytical techniques, experimental methods, and engineering rigor are combined to develop field-friendly tools to characterize and ensure pipeline integrity. Two case studies are included, the first, to demonstrate how the proposed method was used to assess the integrity of a corroded elbow, the second, provides the reader with an example of how to develop a tool for evaluating the severity of dents in pipelines using available public-domain research. It is the hope of the authors that the approach presented in this paper will foster further developments and advanced pipeline integrity management.

El Paso Corporation (El Paso) has experienced substantial growth and management change over the last decade. Most of that growth has been by acquisition, which has significantly increased the environmental liabilities under management. Meanwhile, the Sarbanes-Oxley legislation was emerging from Congress requiring publicly held companies to increase the sophistication and effectiveness of management controls. This article looks at the significant improvements made to the system of management controls and operating philosophy in El Paso’s corporate remediation department during this important time of growth and development.

Full textAbstract:
The 90’s are forcing companies to review all aspects of doing business. Partnerships, alliances and other inter-company relationships are now a matter of course. This paper explores an alternate method currently utilized by one of the major U.S. oil pipelines to acquire products and/or services. The method stresses the formation of long-term alliances to the mutual benefit of both the supplier and the end user companies. The paper uses as an example a SCADA system currently being implemented for this oil company. It outlines the method and explains the pitfalls that have been encountered. As well, the potential benefits to both the supplier and the customer are summarized.

Quinn, Meghan. Geotechnical effects on fiber optic distributed acoustic sensing performance. Engineer Research and Development Center (U.S.), July 2021. http://dx.doi.org/10.21079/11681/41325.
Full textAbstract:
Distributed Acoustic Sensing (DAS) is a fiber optic sensing system that is used for vibration monitoring. At a minimum, DAS is composed of a fiber optic cable and an optic analyzer called an interrogator. The oil and gas industry has used DAS for over a decade to monitor infrastructure such as pipelines for leaks, and in recent years changes in DAS performance over time have been observed for DAS arrays that are buried in the ground. This dissertation investigates the effect that soil type, soil temperature, soil moisture, time in-situ, and vehicle loading have on DAS performance for fiber optic cables buried in soil. This was accomplished through a field testing program involving two newly installed DAS arrays. For the first installation, a new portion of DAS array was added to an existing DAS array installed a decade prior. The new portion of the DAS array was installed in four different soil types: native fill, sand, gravel, and an excavatable flowable fill. Soil moisture and temperature sensors were buried adjacent to the fiber optic cable to monitor seasonal environmental changes over time. Periodic impact testing was performed at set locations along the DAS array for over one year. A second, temporary DAS array was installed to test the effect of vehicle loading on DAS performance. Signal to Noise Ratio (SNR) of the DAS response was used for all the tests to evaluate the system performance. The results of the impact testing program indicated that the portions of the array in gravel performed more consistently over time. Changes in soil moisture or soil temperature did not appear to affect DAS performance. The results also indicated that time DAS performance does change somewhat over time. Performance variance increased in new portions of array in all material types through time. The SNR in portions of the DAS array in native silty sand material dropped slightly, while the SNR in portions of the array in sand fill and flowable fill material decreased significantly over time. This significant change in performance occurred while testing halted from March 2020 to August 2020 due to the Covid-19 pandemic. These significant changes in performance were observed in the new portion of test bed, while the performance of the prior installation remained consistent. It may be that, after some time in-situ, SNR in a DAS array will reach a steady state. Though it is unfortunate that testing was on pause while changes in DAS performance developed, the observed changes emphasize the potential of DAS to be used for infrastructure change-detection monitoring. In the temporary test bed, increasing vehicle loads were observed to increase DAS performance, although there was considerable variability in the measured SNR. The significant variation in DAS response is likely due to various industrial activities on-site and some disturbance to the array while on-boarding and off-boarding vehicles. The results of this experiment indicated that the presence of load on less than 10% of an array channel length may improve DAS performance. Overall, this dissertation provides guidance that can help inform the civil engineering community with respect to installation design recommendations related to DAS used for infrastructure monitoring.
