Urban road construction and the laying of underground pipelines are both important elements in the improvement of urban infrastructure, while the construction of the two may affect and restrict each other if they are not planned systematically. Therefore, a synergistic design of urban roads and pipelines is needed to ensure the synergy of urban road construction and underground pipeline laying. This paper mainly analyzes the necessity of building information modeling (BIM) technology application in the collaborative planning and design of urban roads and pipelines, and explores the application strategy of BIM technology.

Damage to underground water pipes can be traced back to the 1923 Kanto earthquake, and it was well recognized from the early days that seismic effect was important in the construction of underground structures. It was not known, however, how seismic effect could be included in the design and construction of underground structures. In the late 1960s, field measurements and shaking table experiments gradually showed that ground deformation developed during an earthquake induced deformation in underground structures. This finding led to the development of new seismic design for underground structures embedded in subsurface ground. This was first designated as the “seismic deformation method” when the “new seismic design method” was developed as the final accomplishment in a five-year research project by the Ministry of Construction in 1977. In the 1960s and 1970s, Dr. Okubo took the leadership in developing seismic design methods for underground tunnels, pipelines, and bridges. Transportation of aviation petroleum was a critical requirement for the new Narita International Airport. Because no alternatives for transporting aviation petroleum other than pipeline embedded under national roads were possible in congested urban areas, it was important to protect pipelines and roads against seismic effects. When the law for petroleum pipelines went into effect, a seismic design method for petroleum pipelines was included in the notice on technical detailing on petroleum pipelines in 1973. This was the first mandated requirement for underground structures in seismic effects. Subsequently, seismic design based on the seismic deformation method has been extensively used for underground structures. Dr. Toshio Iwasaki, head of the Ground Vibration Division of the Public Works Research Institute of the Ministry of Construction at that time named this method the “seismic deformation method.” The author, a researcher of the Ground Vibration Division at the time, proposed calling it the “deformation method.” Because “deformation method” was widely used in computational structural analysis, Dr. Iwasaki suggested adding “seismic” to “deformation method.” As shown in his paper, Dr. Okubo contributed greatly to clarifying the failure mechanism of seismic damage, and compiled technical knowledge on seismic effect in various design codes. His interest extended beyond underground structures to bridges, roads, and dams. He expanded the foundation of seismic design of civil infrastructures in the early days of earthquake engineering.

Urban underground construction projects are intertwined vertically and horizontally, and adjacent confined spaces such as water supply and drainage pipelines, side ditches and underground canals may exist near buried gas pipelines. Once the buried gas pipeline leaks, the gas will diffuse into the confined space through the soil and even enter the residential room by the confined space, which brings serious potential safety hazards. In this paper, the underground adjacent confined space hazardous boundary (HB) of underground gas pipeline leakage was defined, the distribution properties of gas leakage diffusion flow field were analyzed by numerical simulation and the distribution law of gas entering the confined space was studied. Using the least-squares method and multiple regression theory, the gas concentration prediction model in the adjacent confined space of buried gas pipeline leakage was established, the HB calculation model was further deduced, and the HB drawing board was drawn. The results showed that in the initial stages, the internal and external pressure and velocity distribution of the pipeline near the leakage hole were unstable, reaching a stable state after 60 s, and then the reverse flow occurred in the pipeline downstream of the leak hole. Reducing the minimum construction distance between the buried gas pipeline and the confined space improved the gas distribution concentration in the confined space. When the minimum construction distance increased from 3 m to 9 m, the gas concentration distribution decreased from 90.21% to 0.88%. Meanwhile, increasing the pipeline pressure and leakage diameter enhanced the gas concentration distribution in the confined space. The HB calculation model and HB drawing board realize the rapid determination of the HB between buried gas pipeline and confined space and offer a more reasonable basis for the design of gas pipeline safe distance in urban underground engineering construction.

The underground space in urban areas is frequently congested with utilities, including pipelines and conduits, that are affected by underground construction, e.g., tunneling. This paper carries out finite element (FE) analyses to investigate the effects of tunneling-induced ground movement on pipelines, with special attention to the different soil responses to uplift and downward pipe–soil relative movements. A series of numerical parametric studies with 900 FE simulation runs in total is performed to encompass various combinations of ground settlement profiles, pipe dimensions, material properties, pipe burial depth, and soil properties that are typical for utility pipelines and tunnel construction in urban areas. The results are summarized in a dimensionless plot of relative pipe–soil stiffness versus ratio of maximum pipe curvature to maximum ground curvature, which can be used to directly estimate the maximum pipe bending strain and (or) to directly assess the tunneling-induced risk to pipelines. The FE results and dimensionless plot are validated against field and centrifuge test results reported in the literature. Effect of pipeline orientation with respect to the tunnel centerline is explored. It might be unconservative if design analysis only considers the case that the pipeline is perpendicular to the tunnel centerline.

This paper presents the model, design, and simulation for a navigation system developed for a group of mobile robots dedicated to the production of maps for underground hydraulic infrastructure. The system can operate internally in unknown pipeline networks without GPS support, integrating Tarry’s principles of deep search, Pledge modify discrimination, and topographic orientation transfer, in the temporary construction of a reference network independent of peripheral inertial navigation. The acquisition of topographic objectives for mapping is done by laser collimation and radio frequency synchronization with an angular and longitudinal precision of sigma II range. The maps produced contain the polygonal axes of the network pipelines.

The interaction between underground pipelines and soils is crucial to the design and maintenance of underground pipeline network systems. In this paper, the dynamic stiffness matrix in the frequency-domain of the buried pipeline is obtained by the improved scaled boundary finite element method (SBFEM) coupled with the finite element method (FEM) at the interface between the far and near fields. A new coordinate transformation together with a scaled line is introduced in the improved SBFEM. Combined with the mixed variable algorithm, the time-domain solution of the buried pipeline under dynamic loads is then obtained. The accuracy of the proposed algorithm was verified by numerical examples. A parametric study is performed to assess the influence of the anisotropic characteristics of the layered soils on the dynamic response of the pipeline, the result of which provides a reliable basis for engineering practice. The results show that these parameters have a significant impact on the pipeline. The understanding of this impact can contribute to the design, construction, and maintenance of the corresponding engineering projects.

All work on the construction of pumping and compressor stations is usually divided into two groups of zero cycle work and ground cycle work. The work of the zero cycle includes the preparation of the construction site, earthworks, work on the construction of foundations for buildings, pumping units and technological equipment, work on the construction of underground pipelines and utilities. The work of the ground cycle includes work on the construction of buildings for pumping and compressor shops and auxiliary buildings, installation work on installation and fixing on the foundations in the design position of pumping units. Compressor stations (CS) have been installed along the pipeline route to maintain a certain flow rate of the transported gas and to ensure optimal pressure in the pipeline. A modern compressor station is a complex engineering structure that provides the basic technological processes for the preparation and transportation of natural gas. Keywords: compressor stations, gas pipeline, building structure, Booster compressor stations.

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.

Abstract The work describes the design, construction and commissioning of the underground cosmic-ray experiment Experiment with MultiMuon Array (EMMA). The experiment is built into the Pyhäsalmi mine, in the town of Pyhäjärvi, Finland. The aim of EMMA is to determine the elemental composition of cosmic rays at an energy region around 4 PeV, the energy region called the ’knee’ region. This is achieved by measuring the lateral density distribution of high-energy muons originating from Extensive Air Showers (EAS). The design calculations for the EMMA experiment, which are based on the use of the parametrization of the lateral density distribution of muons, the method of shower reconstruction, and the energy and composition indicators, are presented. A strategy for reconstructing the composition of the cosmic rays is presented and it demonstrates the potential of applying unfolding techniques to the EMMA data. The effect of an array extension on the performance of EMMA is studied. The hardware used in the EMMA experiment is presented starting with an overview of the array and its detector stations. The EMMA array employs three different particle detectors, for which the main technical properties are given, and their use in the EMMA array is presented. A description of the infrastructure of the experiment is given and the rock overburden at the EMMA site at the depth of 80 metres is documented. The work contains the latest analysis of EAS data recorded by the tracking detectors of the experiment, which demonstrates that the experiment is taking data as planned and that the data are according to EAS physics expectations. Methods for event selection and tracking efficiency correction are presented, after which the analysis results of measured track multiplicity spectra are given. The shape of the recorded multiplicity spectrum indicates that the simplest model of a knee-like spectrum with a pure proton composition can not explain the data and that further analysis of the spectrum is required.

Bibliography: pages 81-85.
This thesis addresses some of the issues involved in using numerical methods to simulate the laying of an offshore pipeline, the objective being to contribute to the expertise of the South African offshore technology. Of particular interest is the prediction of the stresses in the pipe during such an event. The thesis concentrates on the use and suitability of the finite element method to simulate the important aspects of the pipelaying problem. ABAQUS, a nonlinear general purpose finite element code, was chosen as numerical tool, and nonlinear effects such as geometry and drag, as well as contact and lift-off at the boundaries, are included in the models. The analysis is performed in two parts: in the static analysis the displaced equilibrium position of the pipeline under self weight, buoyancy and barge tension is sought, whilst the response due to wave action and barge motion is of interest in the dynamic analysis. Numerical experiments show the suitability of ABAQUS to model the behaviour of slender structures under both static loads and dynamic excitations.

The majority of Husky’s fiberglass pipelines in Canada have been used in upstream oil gathering systems to carry corrosive substances. When properly designed and installed, fiberglass pipelines can be maintenance-free (i.e., no requirements for corrosion inhibition and cathodic protection, etc.) However, similar to many other upstream producers, Husky has experienced frequent fiberglass pipeline failures. A pipeline risk assessment was conducted using a load-resistance methodology for the likelihood assessment. Major threats and resistance-to-failure attributes were identified. The significance of each threat and resistance attribute, such as type and grade of pipe, and construction methods (e.g., joining, backfill, and riser connection) were analyzed based on failure statistical correlations. The risk assessment concluded that the most significant threat is construction activity interfering with the existing fiberglass pipe zone embedment. The most important resistance attribute to a fiberglass pipeline failure is appropriate bedding, backfill and compaction, especially at tie-in points. Proper backfilling provides most resistance to ground settlement, frost-heaving, thaw-unstable soil, or pipe movement due to residual stress or thermal, and pressure shocks. A technical analysis to identify risk mitigation options with the support of fiberglass pipe supplier and distributors was conducted. To reduce the risk of fiberglass pipeline failures, a formal backfill review process was adopted; and a general pipeline tie-in/repair procedure checklist was developed and incorporated into the maintenance procedure manual to improve the workmanship quality. Proactive mitigation options were also investigated to prevent failures on high risk fiberglass pipelines.

In response to industry demand, Hardisty Caverns Limited Partnership (HCLP) has developed cost effective underground storage facilities with a capacity to store 480,000 m3 (3 million barrels) of crude oil. This project is unique through the integration of existing underground salt caverns into a significant North American crude oil transportation hub. Annually, 64 million cubic meters (400 million barrels) of oil move through this hub. This project utilizes existing caverns developed in the late 1960’s. Significant work was required to upgrade the cavern facilities and to construct new surface facilities to integrate the caverns into the crude oil transportation hub. Remote operation of the facility is performed from a control centre in Edmonton. In this paper, the key features of the design and construction of the Hardisty Cavern Storage Project will be presented. Of particular interest are the unique challenges presented due to hydraulic considerations related to cavern operation with multiple product characteristics and to provide crude oil movements exchanges between the cavern storage facilities and both low flow rate feeder pipelines and high flow rate transportation pipelines.

With the rapid development of oil and gas pipeline construction, there are more and more pipelines have to pass through the mineral deposits area. The surface cracking, subsidence and collapse will be occurred commonly because of the underground goaf after exploitation in mineral deposits area, and pipelines’ safety is faced with hidden troubles. In order to solve the contradiction between the pipeline construction and minerals mining, some research on design method of pipeline in mined-out area was carried out. The goaf subsidence prediction is constituted of subsidence influence factors analysis, surface deformation law analysis and surface deformation forecast. Pipe stress analysis includes stress influence factors analysis and stress model analysis. Combining the pipeline influence factors with the forecasted surface deformation, the pipeline stress analysis model could be built. This paper describes methods developed for the ground surface displacement prediction and the mechanical model of the pipeline/ soil interaction, and some application examples in china.

The operation of gas pipelines in utility corridor of a metropolitan city in a developing country has unique challenges. Through this paper, I would like to discuss the threats and mitigation measures in city area pipelines so as to ensure Pipeline Integrity. Excavations keep occurring because of various developmental activities. Construction of Flyovers, roads and subways disturb the pipeline route constantly necessitating Shifting / lowering of operating pipelines. Fault rectification by other agencies sharing the corridor, and proximity of High Voltage lines have also led to incidents resulting in gas leakage. Pipeline Integrity Surveys have been carried out in Delhi area and based on their recommendations, as well as a result of analysis of various incidents that have occurred in the past, a mitigation plan was developed. All the points were complied to ensure the safety and Integrity of pipelines. As can be seen from the various case studies of the past, often risky situations arise due to absence of proper layout design of underground facilities. Liaising with utility corridor agencies and appointing a central regulator for utility corridor, mapping and allocating work permits in the corridor with the help of Geographical Information System (GIS) and other advanced mapping and remote sensors, could become an effective solution. GAIL has developed a GIS for Delhi area pipelines which is proving very useful. To ensure the integrity and safety of the pipeline, a proactive approach is required. Integrity management of Pipelines is a continuous process. Evaluation has to be done constantly and newer steps should be taken each time if required.

Thin film coatings, such as fusion bonded epoxy (FBE) coatings have become more popular as an underground pipeline coating especially on large diameter pipelines. This together with improved construction techniques has resulted in very effective coatings. They do however present additional considerations in a cathodic protection design. This paper deals with some issues that one must bear in mind related to cathodic protection when dealing with these superior coatings including a modification to empirical data in cathodic protection pre-designs, an upper polarized potential to prevent cathodic disbondment, inspection in horizontal directionally drilled crossings, an increased effect of telluric currents and an increased possibility of hazardous induced AC potentials. Examples are presented and discussed.

It is common practice during the construction of underground pipelines that pipe sections are welded together at surface level and then lowered into a pre-dug trench. Lowering of the pipeline into the trench incurs bending and/or torsional stresses that are not typically considered during the design of the pipeline. Current industry guidelines recommend the pipelines be lowered into the trenches with care in order to avoid cracking of the pipe, or yielding that could lead to residual stresses and distortion. There are currently no formal guidelines on how to minimize these stresses, or estimates of the magnitude of stresses associated with these operations. The stresses incurred during the laying of pipe can be estimated using simple beam bending and torsion equations. One can simplify the analysis by assuming the pipeline is either a cantilever with a given load or deflection at one end, or, a beam with given loads, deflections and rotations at both ends. The choice of boundary conditions influences the calculated stresses, and can be considered appropriate for different pipe laying operations. If a pipeline is moved laterally during the laying operations one must consider the associated torsional stresses. The combination of bending and torsional stresses will lead to different stress states on different sides of the pipe, some of which may result in cracking or yielding. The goal of this work is to develop a framework for estimating the stresses incurred in pipe during laying operations, as a function of pipe length, deflection, diameter and wall thickness. This will allow guidelines to be developed that will allow construction crews to ensure that pipelines are laid with minimal damage. A variety of analyses has been considered during the course of this work and is presented in this paper. It is expected that discussion of these analyses with industry representatives will lead to improved construction protocols.

Abstract There is an old adage “if it is not broken, do not fix it” and this could be applicable for our day-to-day menial activities, but could prove fatally disastrous if followed by any pipeline owners globally. Although, pipelines are statistically the safest means of transporting hydrocarbon — the consequence to an event could be exponential, even if the probability of the event to occur is low. The magnitude of consequence only goes higher with the ever-burgeoning population. To this effect, Oil India Limited (OIL) owns an intensive network of spider-webbed carbon steel pipelines in Upper Assam, India geographical area with varying vintage. Understanding the associated risks of operating such critical pipeline systems, it was decided for the pipelines to undergo code-compliant integrity assessment. It is well known that non-CP protected pipelines are electrically continuous conductors without any insulation (isolation) joints to separate the above-ground station piping to the cross-country underground pipeline sections. With respect to this, OIL deployed a state-of-the-art integrated indirect inspection survey tool to assist in conducting Direct Assessment based integrity assessment. This paper provides an insight into such a scenario where the operator proactively employed the use of advanced high-resolution integrated survey technology to their non-cathodically protected, but coated pipeline assets. Due to the age and design of these “temporary” pipeline systems, there were no prior readily available records in terms of construction, drawings, maps, alignment sheets, operational or historical maintenance data for these pipelines. The advanced Integrated survey played a vital role in decluttering these extensively jumbled network of non-CP pipelines. Firstly, by actually locating the pipeline based on sub meter accuracy and secondly performing simultaneous above ground survey for coating assessment and susceptibility for corrosion. The adaptability of integrated survey as per given situation helped overcome the difficult pipeline route conditions and customize the assessment for these highly challenging pipelines and make ECDA feasible as per NACE SP0502 Standard Practice for this very complex spider web network of pipelines.

One of the most common and practical difficulties a pipeline engineer faces at the initial stage of the project is the lack of Soil survey data. Hence, various soil parameters like soil type, density, friction angle, cohesive pressure, depth of cover, pipe coating etc. are needed to be assumed. The critical designs like anchor block requirement, pipe route changes, support loads which involve a huge cost are required to be ‘Issued for Construction’ based on assumed data. This paper briefly illustrates and compares the results obtained from the two most common buried pipe stress analysis methods viz. ‘American Lifeline Alliance - Appendix B’ (1) and ‘Stress Analysis Methods for Underground Pipelines’ (2) and shows their effects graphically on the various Stress Analysis results like pipe movement, end force, active length (virtual anchor length) and bending stress generated in the buried pipeline. Further, this paper comes up with an unique application of ANOVA, a Statistical method, to find out the most significant soil parameter affecting the said results. The paper explains this method with a solved example. These results are useful for a pipeline engineer to determine the governing soil parameter in the design and thus provide a useful tool to make optimum assumptions in absence of soil data so as to minimize the changes in future design and helps saving the cost of the project due to rework.
