The initial phase of a pipeline integrity management program (IMP) is conducting a baseline assessment of the pipeline system and segments as part of Quantitative Risk Assessment (QRA). This gives the operator's integrity team the opportunity to identify critical areas and deficiencies in the protection, maintenance, and mitigation strategies. As a part of data gathering and integration of a wide variety of sources, in-line inspection (ILI) data is a key element. In order to move forward in the integrity program development and execution, the baseline geometry of the pipeline must be determined with accuracy and confidence. From this, all subsequent analysis and conclusions will be derived. Tuboscope Pipeline Services (TPS), in conjunction with Pipeway Engenharia of Brazil, operate ILI inertial navigation system (INS) and Caliper geometry tools, to address this integrity requirement. This INS and Caliper ILI tool data provides pipeline trajectory at centimeter level resolution and sub-metre 3D position accuracy along with internal geometry - ovality, dents, misalignment, and wrinkle/buckle characterization. Global strain can be derived from precise INS curvature measurements and departure from the initial pipeline state. Accurate pipeline elevation profile data is essential in the identification of sag/over bend sections for fluid dynamic and hydrostatic calculations. This data, along with pipeline construction, operations, direct assessment and maintenance data is integrated in LinaViewPRO{sup TM}, a pipeline data management system for decision support functions, and subsequent QRA operations. This technology provides the baseline for an informed, accurate and confident integrity management program. This paper/presentation will detail these aspects of an effective IMP, and experience will be presented, showing the benefits for liquid and gas pipeline systems. (author)

This paper presents the implementation by PETROBRAS Transporte S.A. - TRANSPETRO of its Oil Pipelines and Terminals Standardization Program (PRONOT) within the scope of the 'Integrated Management System' (IMS). This program, launched in 2006 in the regions where the company operates, aims at standardizing all of its oil pipeline and terminal operations. Its implementation was planned in two phases: the first, already successfully concluded, refers to pipeline operations, industrial maintenance and right-of-way activities management; and the second, initiated in 2009, encompasses cross-sectional activities including health, safety and environment (HSE); training and development of oil pipeline workforce; communication with stake holders; oil pipeline integrity; and engineering project requirements. The documental structures of TRANSPETRO IMS and PRONOT are described and represented graphically to emphasize the intentional alignment of the standardization process carried out by the Oil Pipelines and Terminals Unit to the corporate IMS, based upon national and international literature review and through practical research focusing on the best international practices.

A Software for 'pipeline integrity management' was developed. It allows to deal with Geographical Information and a PODS database (Pipeline Open database Standard) simultaneously, in a simple and reliable way. The premises for the design were the following: didactic, geo referenced, multiple reference systems. Program skills: 1.PODS+GIS: the PODS database in which the software is based on is completely integrated with the GIS module. 2 Management of different kinds of information: it allows to manage information on facilities, repairs, interventions, physical inspections, geographical characteristics, compliance with regulations, training, offline events, operation measures, O and M information treatment and importing specific data and studies in a massive way. It also assures the integrity of the loaded information. 3 Right of way survey: it allows to verify the class location, ROW occupation, sensitive areas identification and to manage landowners. 4 Risk analysis: it is done in a qualitative way, depending on the entered data, allowing the user to identify the riskiest stretches of the system. Either results from risk analysis, data and consultations made about the database, can be exported to standard formats. (author)

The implementation of an Integrity Management Program (IMP) in a crude oil pipeline system is focused on the accomplishment of two primary corporative objectives: to increase safety operation margins and to optimize available resources. A proactive work philosophy ensures the safe and reliable operation of the pipeline in accordance with current legislation. The Integrity Management Program is accomplished by means of an interdisciplinary team that defines the strategic objectives that complement and are compatible with the corporative strategic business plan. The implementation of the program is based on the analysis of the risks due to external corrosion, third party damage, design and operations, and the definition of appropriate mitigation, inspection and monitoring actions, which will ensure long-term integrity of the assets. By means of a statistical propagation model of the external defects, reported by high-resolution magnetic inspection tool (MFL), together with the information provided by corrosion sensors, field repair interventions, close internal surveys and operation data, projected defect depth; remaining strength and failure probability distributions were obtained. From the analysis, feasible courses of action were established, including the inspection and repair plan, the internal inspection program and both corrosion monitoring and mitigation programs.

Due to the growing relevance of safety and environmental protection policies in PETROBRAS and its subsidiaries, as well as official regulatory agencies and population requirements, integrity management of oil and gas pipelines became a priority activity in TRANSPETRO, involving several sectors of the company's Support Management Department. Inspection activities using intelligent PIGs, field correlations and replacement of pipeline segments are known as high cost operations and request complex logistics. Thus, it is imperative the adoption of management tools that optimize the available resources. This study presents Monte Carlo simulation method as an additional tool for evaluation and management of pipeline structural integrity. The method consists in foreseeing future physical conditions of most significant defects found in intelligent PIG In Line Inspections based on a probabilistic approach. Through Monte Carlo simulation, probability functions of failure for each defect are produced, helping managers to decide which repairs should be executed in order to reach the desired or accepted risk level. The case that illustrates this study refers to the reconditioning of ORSOL 14'' (35,56 mm) pipeline. This pipeline was constructed to transfer petroleum from Urucu's production fields to Solimoes port, in Coari, city in Brazilian Amazon Region. The result of this analysis indicated critical points for repair, in addition to the results obtained by the conventional evaluation (deterministic ASME B-31G method). Due to the difficulties to mobilize staff and execute necessary repairs in remote areas like Amazon forest, the probabilistic tool was extremely useful, improving pipeline integrity level and avoiding future additional costs.

In this paper we present the unique and innovative 'Integriti' pipeline and flow line integrity monitoring system developed by Schlumberger in collaboration with BP. The system uses optical fiber distributed sensors to provide simultaneous distributed measurements of temperature, strain and vibration for the detection, monitoring, and location of events including: Third Party Interference (TPI), including multiple simultaneous disturbances; geo-hazards and landslides; gas and oil leaks; permafrost protection. The Integriti technology also provides a unique means for tracking the progress of cleaning and instrumented pigs using existing optical telecom and data communications cables buried close to pipelines. The Integriti solution provides a unique and proactive approach to pipeline integrity management. It performs analysis of a combination of measurands to provide the pipeline operator with an event recognition and location capability, in effect providing a hazard warning system, and offering the operator the potential to take early action to prevent loss. Through the use of remote, optically powered amplification, an unprecedented detection range of 100 km is possible without the need for any electronics and therefore remote power in the field. A system can thus monitor 200 km of pipeline when configured to monitor 100 km upstream and downstream from a single location. As well as detecting conditions and events leading to leaks, this fully integrated system provides a means of detecting and locating small leaks in gas pipelines below the threshold of present online leak detection systems based on monitoring flow parameters. Other significant benefits include: potential reductions in construction costs; enhancement of the operator's existing integrity management program; potential reductions in surveillance costs and HSE risks. In addition to onshore pipeline systems this combination of functionality and range is available for practicable

COMGAS is the largest natural gas distributing company in Brazil, having more than 700,000 costumers. Gas delivery to this customer base is achieved through a network of high-pressure steel pipelines (17 and 35 bar) with around 1,100 km (690 miles) in length, the majority operating inside urban areas. The Integrity Management of this network is a particularly difficult task since neither pigging nor hydrostatic testing can be used to inspect the existing pipelines. Direct Assessment (DA) is the only assessment technique available at the moment. As an initial stage COMGAS has implemented an innovative project called SIA (Sistema de Integridade de Ativos). SIA combines functionality targeted for guiding and implementing an External Corrosion Assessment (ECDA) procedure, with full data alignment and integration, corporate policies on safety and dedicated reporting capabilities. Seamless interaction between SIA and the existing Operations GIS system was a key specification requirement for the construction of the system. This paper describes the lessons learned during the implementation of the ECDA module of the SIA, the first application experiences of the ECDA process with the support of the module and the initial benefits obtained from the use of the new Integrity Management System.

There are many internationally recognized codes and standards, such as API 1160 and ASME B31.8S, which help pipeline operators to manage and maintain the integrity of their pipeline networks. However, operators in many countries still use local codes that often reflect the history of pipeline developments in their region and are based on direct experience and research on their pipelines. As pipeline companies come under increasing regulatory and financial pressures to maintain the integrity of their networks, it is important that operators using regional codes are able to benchmark their integrity management schemes against these international standards. Any comprehensive Pipeline Integrity Management System (PIMS) software package should therefore not only incorporate industry standards for pipeline integrity assessment but also be capable of implementing regional codes for comparison purposes. This paper describes the challenges and benefits of incorporating one such set of regional pipeline standards into ROSEN Asset Integrity Management Software (ROAIMS). (author)

To control the integrity of a buried gas pipeline system is not an easy task for a gas pipeline operator. As the threats that affect pipeline integrity are many, it is critical to obtain, visualize, and analyze a great quantity of data in order to ensure a safe and continuous gas supply. This task becomes even more complex in the case of pipelines installed long time ago, where time pays an important role in the formation and development of defects. It is essential to maintain a policy of permanent evaluation, monitoring and repair that allows to evaluate the integrity plan developed and to make the changes that might be necessary. The TGS pipeline system consists of 7400 Km of pipe with an average age of 30 years, going across a great variety of soils and zones with distinctive geographical features that demand the continuous investment of money. This study describes the integrity plan set up by TGS and its evolution in time, including the main tasks related to information gathering and analysis, as well as all rehabilitation tasks. The evaluation of the integrity plan implementation, and the evolution of failure rates in time with respect to the related investments are also described. Finally, the analysis includes the information management systems applied by TGS such as the Geographic Information System . (author)

Pipeline operators are continuously working to improve the safety of their systems and operations. In the US both liquid and gas pipeline operators have worked with the regulators over many years to develop more systematic approaches to pipeline integrity management. To successfully manage pipeline integrity, vast amounts of data from different sources needs to be collected, overlaid and analyzed in order to assess the current condition and predict future degradation. The efforts undertaken by the operators has had a significant impact on pipeline safety, nevertheless, during recent years we have seen a number of major high profile accidents. One can therefore ask how effective the pipeline integrity management systems and processes are. This paper will present one methodology 'The Pipeline System Operability Review' that can evaluate and rate the effectiveness of both the management systems and procedures, as well as the technical condition of the hardware. The result from the review can be used to compare the performance of different pipelines within one operating company, as well as benchmark with international best practices. (author)

The increasing expansion of the oil and gas industry in Brazil, the current legal requirements relating to security, health and environment in the industrial installations, is necessary that the companies, responsible by the operation of pipelines for oil and gas transport, adopt efficient techniques to assure the operational continuity of these of trustworthy form and insurance. To fulfill this important function it is important that the companies implement a management program to control and register the integrity of the pipelines during the all operational life cycle. Inside of this context of management of the integrity of pipelines, the DNV developed the software ORBIT Pipeline with the intention to serve as an important tool to monitor the technique and security condition of the pipeline, to define the frequency and content technician of the inspection program and to recommend the work of intervention or repair in pipeline when necessary. Additionally to these activities that are carried through directly in the ORBIT Pipeline, also an evaluation of the activity of third part and the land/soil movement is made inside of the systematic for analysis of integrity and risk for onshore pipelines performed by DNV.

A 30-inch crude oil pipeline system was built between Nuevo Teapa to Venta de Carpjo from 1978 to 1980. It is owned by Pemex; its total length is 570 km, and it has strategic importance in Mexico's refining capability. In this oil pipeline, various degrees of external and internal corrosion have been found, and recent incidents occurred as a result of stress corrosion cracking (SCC). This paper presents an approach for managing high pH SCC in such a pipeline: it includes a comprehensive verification excavation plan, a strict in-ditch NDT investigation protocol, statistical models to determine the probability of detection and identification, sizing tolerance analyses, and an assessment methodology that is backed up by the material testing program. All the results provided by the application of the approach lead to the development of integrity management strategies. An integrity management plan is established and refined before the next inspection.

Song, Peter; Lawrence, Doug; Keane, Sean; Ironside, Scott; Sutton, Aaron [Enbridge Pipelines Inc., Edmonton, AB (Canada)

2010-07-01

Enbridge Pipelines Inc. undertook a pressure cycling monitoring (PCM) program to see how pressure cycling severity (PCS) changes during line operations. The main purpose of this program is to make sure the integrity assessment interval is valid and to identify changes in operations that cause fatigue damage. The estimated fatigue life is obtained through fatigue analysis, which is based on Paris Law and uses certain data such as the operating pressure data from Enbridge's SCADA system. It serves as a measure of the PCS. When applied in an integrity management program, PCM helps maintain the integrity of pipelines by pinpointing segments whose operations have changed significantly. Among useful conclusions, it was found that a comparison between crack threat susceptibility indicators and PCS fluctuations help identify a change to crack threat susceptibility; also, the program helps identify notable changes to PCS that are caused by certain operational practices.

Simard, T.S.

1998-01-01

Managing the risk involved in adding new pipeline capacity was explored in this presentation. Topics discussed included: (1) pipeline capacity positions as basis swaps, (2) physical capacity versus basis transactions, (3) managing the market price risk in a capacity position, and (4) sharing of pipeline market risk. Pipeline owners were advised to recognize that pipeline capacity carries significant market price risk, that basis markets can sometimes be more volatile than outright markets, and to treat physical capacity market risk the same way as one would treat a financial basis position. 2 figs

Analysis pipelines are an essential part of bioinformatics research, and ad hoc pipelines are frequently created by researchers for prototyping and proof-of-concept purposes. However, most existing pipeline management system or workflow engines are too complex for rapid prototyping or learning the pipeline concept. A lightweight, user-friendly and flexible solution is thus desirable. In this study, we developed a new pipeline construction and maintenance tool, PipelineDog. This is a web-based integrated development environment with a modern web graphical user interface. It offers cross-platform compatibility, project management capabilities, code formatting and error checking functions and an online repository. It uses an easy-to-read/write script system that encourages code reuse. With the online repository, it also encourages sharing of pipelines, which enhances analysis reproducibility and accountability. For most users, PipelineDog requires no software installation. Overall, this web application provides a way to rapidly create and easily manage pipelines. PipelineDog web app is freely available at http://web.pipeline.dog. The command line version is available at http://www.npmjs.com/package/pipelinedog and online repository at http://repo.pipeline.dog. ysun@kean.edu or xing@biology.rutgers.edu or ysun@diagnoa.com.

In 2001 PETROBRAS implemented a new Standard for Pipeline Structural Integrity Management of PETROBRAS (PID). All pipelines operated by PETROBRAS had to be adapted to the new requirements imposed by this Standard. When this standard was applied to the Guanabara Bay pipeline many facilities had to be adapted, new inspection procedures implemented and inspection reports reviewed. The first action was to map all pipelines, using a range of techniques, to determine their accurate 3D position. The sections not buried were inspected by divers to identify free spans that exceeded the recommended limits. Launchers were installed in the lines going to the piers to allow in-line inspection. This inspection detected many dents caused by vessels, internal corrosion and external corrosion in the inter-tidal zone. The corrosion monitoring system was redesigned and new monitoring points were installed to provide more accurate information on the high risk areas. The cathodic protection system was adapted to provide remote monitoring and data analysis. A new routine of geotechnical inspections, on-shore inspections and helicopter surveys has been implemented. Defects identified by the in-line inspection have been assessed in a conservative way and all lines have been hydrostatically tested to demonstrate continued fitness for purpose. (author)

The benefits of SCADA integrated pipeline leak detection

Pichler, Ruprecht M.J. [Pichler Engineering GmbH, Munich (Germany)

2003-07-01

Software based leak detection and locating for pipelines based upon evaluation of hydraulic parameters is a widely used approach to online pipeline integrity monitoring. Typically, these software packages are installed in a stand-alone configuration with a narrow bandwidth interface to the pipeline SCADA system. However, the performance characteristics of the SCADA system and interface do have a substantial impact on the performance of the leak detection system. By a tight integration of leak detection software into the SCADA system, a source of false alarms typically experienced with leak detection systems can be eliminated, the overall performance of the leak detection system can be improved, and the project costs can be reduced.

In this paper, the authors present an approach as an overall framework for the estimation of the failure probability of pipelines based on: the results of the deterministic-probabilistic structural integrity analysis (taking into account loads, material properties, geometry, boundary conditions, crack size, and defected zone thickness), the corrosion rate, the number of defects and failure data (involved into the model via application of Bayesian method). The proposed approach is applied to estimate the failure probability of a selected part of the Lithuanian natural gas transmission network. The presented approach for the estimation of integrated failure probability is a combination of several different analyses allowing us to obtain: the critical crack's length and depth, the failure probability of the defected zone thickness, dependency of the failure probability on the age of the natural gas transmission pipeline. A model's uncertainty analysis and uncertainty propagation analysis are performed, as well. - Highlights: • Degradation mechanisms of natural gas transmission pipelines. • Fracture mechanic analysis of the pipe with crack. • Stress evaluation of the pipe with critical crack. • Deterministic-probabilistic structural integrity analysis of gas pipeline. • Integrated estimation of pipeline failure probability by Bayesian method.

Integrity assessment of pipelines is part of a process that aims to enhance the operating safety of pipelines. During this task, questions related to the interpretation of inspection reports and the way of regarding the impact of several parameters on the pipeline integrity normally come up. In order to satisfactorily answer such questions, the integrity assessment team must be able to suitably approach different subjects such as corrosion control and monitoring, assessment of metal loss and geometric anomalies, and third party activities. This paper presents additional remarks on some of these questions based on the integrity assessment of almost fifty pipelines that has been done at PETROBRAS/E and P Bahia over the past eight years.

Pipelines are regarded by many as passive structures with the technology involved in their construction and operation being viewed as relatively simple and stable. If such is the case how can there be much room for cost improvement? In reality, there have been many technological and regulatory innovations required within the pipeline industry to meet the challenges posed by ever increasing consumer demand for hydrocarbons, the effects of aging infrastructure and a need to control operating and maintenance expenditures. The importance of technology management, as a subset of overall project management, is a key element of life cycle cost control. Assurance of public safety and the integrity of the system are other key elements in ensuring a successful pipeline project. The essentials of best practise project management from an owner/ operator's perspective are set out in the paper. Particular attention is paid to the appropriate introduction of new technology, strategic procurement practice and material selection, indicating that capital cost savings of up to 15% are achievable without harming life cycle cost. The value of partnering leading to technical innovation, cost savings and improved profitability for all the participants is described. Partnering also helps avoid duplicated effort through the use of common tools for design, planning schedule tracking and reporting. Investing in appropriate technology development has been a major source of cost reduction in recent years and the impact of a number of these recently introduced technologies in the areas of materials, construction processes and operation and maintenance are discussed in the paper.

Open source single nucleotide polymorphism (SNP) discovery pipelines for next generation sequencing data commonly requires working knowledge of command line interface, massive computational resources and expertise which is a daunting task for biologists. Further, the SNP information generated may not be readily used for downstream processes such as genotyping. Hence, a comprehensive pipeline has been developed by integrating several open source next generation sequencing (NGS) tools along with a graphical user interface called Integrated SNP Mining and Utilization (ISMU) for SNP discovery and their utilization by developing genotyping assays. The pipeline features functionalities such as pre-processing of raw data, integration of open source alignment tools (Bowtie2, BWA, Maq, NovoAlign and SOAP2), SNP prediction (SAMtools/SOAPsnp/CNS2snp and CbCC) methods and interfaces for developing genotyping assays. The pipeline outputs a list of high quality SNPs between all pairwise combinations of genotypes analyzed, in addition to the reference genome/sequence. Visualization tools (Tablet and Flapjack) integrated into the pipeline enable inspection of the alignment and errors, if any. The pipeline also provides a confidence score or polymorphism information content value with flanking sequences for identified SNPs in standard format required for developing marker genotyping (KASP and Golden Gate) assays. The pipeline enables users to process a range of NGS datasets such as whole genome re-sequencing, restriction site associated DNA sequencing and transcriptome sequencing data at a fast speed. The pipeline is very useful for plant genetics and breeding community with no computational expertise in order to discover SNPs and utilize in genomics, genetics and breeding studies. The pipeline has been parallelized to process huge datasets of next generation sequencing. It has been developed in Java language and is available at http://hpc.icrisat.cgiar.org/ISMU as a standalone

Chebouba, A

2015-01-01

This paper addresses the Line Pack Management of the ''GZ1 Hassi R'mell-Arzew'' gas pipeline. For a gas pipeline system, the decision-making on the gas line pack management scenarios usually involves a delicate balance between minimization of the fuel consumption in the compression stations and maximizing gas line pack. In order to select an acceptable Line Pack Management of Gas Pipeline scenario from these two angles for ''GZ1 Hassi R'mell- Arzew'' gas pipeline, the idea of multi-objective decision-making has been introduced. The first step in developing this approach is the derivation of a numerical method to analyze the flow through the pipeline under transient isothermal conditions. In this paper, the solver NSGA-II of the modeFRONTIER, coupled with a matlab program was used for solving the multi-objective problem

2009-07-01

Pemex Refinacion and NDT Systems and Services, executed a Total Integrated Maintenance Program of the Process Pipeline System in the Yucatan Peninsula in Mexico, in order to modernize, enhance and bring the pipeline system up to the best industry standards and ensure the integrity, reliability and safe operation of the system. This approach consisted in using multi-diameter ultrasonic inspection technology to determine the current status of the pipelines, repair every 'integrity diminishing' feature present on the system and establish a Certified Maintenance Program to ensure the future reliability and safety of the pipelines. Due to the complex nature of the pipeline construction, dated from 1984, several special modifications, integrations and solutions were necessary to improve the in line inspection survey as for all traditionally unpiggable systems. The Progreso Pipeline System consists in 3 major pipelines which transport diesel, jet fuel and gasoline respectively. The outside diameter of two pipelines varies along its length between 12 inches - 14 inches - 16 inches, making the inspection survey more difficult and particularly demanding an Inspection Tool solution. It is located on the coast of the Yucatan Peninsula, at the Mexican Caribbean, and its main purpose is to transport the product from the docked tanker ships to the Pemex Storage and Distribution Terminal.

Applied methodology for replacement pipe arcs in integral pipelines TE 'Oslomej'

Directory of Open Access Journals (Sweden)

Temelkoska Bratica K.

2016-01-01

Full Text Available The integral pipelines in thermal power plants present a linear spatial bearing construction with high operating parameters, complex static and dynamic load. The integral pipelines along its entire length are hanging on construction spring hangers from the boiler building, where the boiler is placed, next to the machine hall where the turbine is placed. Therefore, it is important to monitor the condition and to remove any possible defects from the applied methods. This paper describes the methodology of replacement of the pipe arch on one of the integral pipelines-the line for hot superheated steam. In addition, in this paper are given the method methods that led to this methodology for testing and evaluation of the condition of the pipe arch material that had been in exploitation and the new pipe arch that will be embedded. Furthermore the approach, the technology of replacement, anchoring of the steam line, technology of welding etc., as well as the preparation of the final design of constructed condition are also covered in this paper.

Solving an unpiggable pipeline challenge

Technically, any pipeline can be retrofitted to enable in line inspection. Sensibly however, the expense of excavations and construction of permanent facilities have been, in many cases, exceedingly prohibitive. Even where traditional modifications are feasible from engineering perspectives, flow interruption may not be an option - either because they are critical supply lines or because the associated lost revenues could be nearly insurmountable. Savvy pipeline integrity managers know the safety issue that is at stake over the long term. They are also well aware of the accuracy benefits that high-quality in-line inspection data offer over potentially supply disruptive alternatives such as hydrostatic testing. To complicate matters further, many operators, particularly in the US, now face regulatory pressure to assess the integrity of their yet-uninspected pipelines located in highly populated areas. This paper describes an important project National Grid undertook that made use of a unique pipeline access method that did not require permanent installation of expensive facilities required for in line inspection of a pipeline previously considered 'unpiggable'. Since the pipeline was located in an urban area, flow disruption had to be minimized. This paper will define the project background, its challenges, outcomes and lessons learned for the future.

This paper describes a risk based approach and inspection planning as part of the Pipeline Integrity Management (PIM) system for the 95.5 km long 18'' GASVOL gas pipeline in the South eastern region of Brazil transporting circa 5 000 000 m3 dry gas per day. Pipeline systems can be subject to several degradation mechanisms and inspection and monitoring are used to ensure system integrity. Modern pipeline regulations and codes are normally based on a core safety or risk philosophy. The detailed design requirements presented in design codes are practical interpretations established so as to fulfill these core objectives. A given pipeline, designed, constructed and installed according to a pipeline code is therefore the realization of a structure, which, along its whole length, meets the applicable safety objectives of that code. The main objective of Pipeline Integrity Management (PIM) is to control and document the integrity of the pipeline for its whole service life, and to do this in a cost-effective manner. DNV has a specific approach to RBI planning, starting with an initial qualitative assessment where pipelines and damage type are ranked according to risk and potential risk reduction by an inspection and then carried forward to a quantitative detailed assessment where the level of complexity and accuracy can vary based on availability of information and owner needs. Detailed assessment requires significant effort in data gathering. The findings are dependent upon the accuracy of the inspection data, and on DNV's interpretation of the pipeline reference system and simplifications in the inspection data reported. The following specific failure mechanisms were investigated: internal corrosion, external corrosion, third party interference, landslides and black powder. RBI planning, in general words, is a 'living process'. In order to optimize future inspections, it is essential that the analyses utilize the most recent information regarding

The ethos of the neuroimaging field is quickly moving towards the open sharing of resources, including both imaging databases and processing tools. As a neuroimaging database represents a large volume of datasets and as neuroimaging processing pipelines are composed of heterogeneous, computationally intensive tools, such open sharing raises specific computational challenges. This motivates the design of novel dedicated computing infrastructures. This paper describes an interface between PSOM, a code-oriented pipeline development framework, and CBRAIN, a web-oriented platform for grid computing. This interface was used to integrate a PSOM-compliant pipeline for preprocessing of structural and functional magnetic resonance imaging into CBRAIN. We further tested the capacity of our infrastructure to handle a real large-scale project. A neuroimaging database including close to 1000 subjects was preprocessed using our interface and publicly released to help the participants of the ADHD-200 international competition. This successful experiment demonstrated that our integrated grid-computing platform is a powerful solution for high-throughput pipeline analysis in the field of neuroimaging.

The execution of the OSBAT 24{sup o}il pipeline rehabilitation project, comprising the substitution of a 30 km section of the 37 years old pipeline has become a real benchmark in the history of this kind of job. The pipeline is inserted in one of the most sensitive environmental areas of the Sao Paulo State - the last Environmental Protection Area of the Mata Atlantica . The growth of human presence in its surroundings during the last three decades, has caused the right-of-way to be totally confined by luxury housing developments, streets, highways and resorts, as well as by the local communities and their activities, schools, and commerce. The pipeline runs through the Serra do Mar unstable mountain range slopes, with sequences of very steep hills and ravines followed by swamps and rivers. The success of such a challenging project - assembling the new line in a narrow ROW with all its restrictions, where the old line was still in operation, and complying with the tight work schedule required by PETROBRAS, was only possible due to a carefully managed combination of: accurate planning, best engineering methods and equipment and experienced workforce, deeply integrated in a massive effort towards safety, environmental care and social responsibility.

Since the early beginnings in the sixties and seventies, Structural Reliability theory has reached a mature stage encompassing solid theoretical developments and increasing practical applications. Structural reliability methods have permeated the engineering profession, finding applications in code calibration, structural optimization, life extension of existing structures, life-cycle management of infrastructure risks and costs, and so on. This review paper shows that the ground work for Reliability Based Design and Assessment (RBDA) of onshore pipeline systems is already developed. Hence, this allows the economic management of the risks involved in operation of pipeline systems. It is shown that RBDA is a rational tool to safely manage the operational life of pipeline systems, optimizing initial design and the expenditures in inspection and maintenance operations. (author)

United States petroleum pipelines: An empirical analysis of pipeline sizing

Science.gov (United States)

Coburn, L. L.

1980-12-01

The undersizing theory hypothesizes that integrated oil companies have a strong economic incentive to size the petroleum pipelines they own and ship over in a way that means that some of the demand must utilize higher cost alternatives. The DOJ theory posits that excess or monopoly profits are earned due to the natural monopoly characteristics of petroleum pipelines and the existence of market power in some pipelines at either the upstream or downstream market. The theory holds that independent petroleum pipelines owned by companies not otherwise affiliated with the petroleum industry (independent pipelines) do not have these incentives and all the efficiencies of pipeline transportation are passed to the ultimate consumer. Integrated oil companies on the other hand, keep these cost efficiencies for themselves in the form of excess profits.

A review on pipeline corrosion, in-line inspection (ILI), and corrosion growth rate models

International Nuclear Information System (INIS)

Vanaei, H.R.; Eslami, A.; Egbewande, A.

2017-01-01

Pipelines are the very important energy transmission systems. Over time, pipelines can corrode. While corrosion could be detected by in-line inspection (ILI) tools, corrosion growth rate prediction in pipelines is usually done through corrosion rate models. For pipeline integrity management and planning selecting the proper corrosion ILI tool and also corrosion growth rate model is important and can lead to significant savings and safer pipe operation. In this paper common forms of pipeline corrosion, state of the art ILI tools, and also corrosion growth rate models are reviewed. The common forms of pipeline corrosion introduced in this paper are Uniform/General Corrosion, Pitting Corrosion, Cavitation and Erosion Corrosion, Stray Current Corrosion, Micro-Bacterial Influenced Corrosion (MIC). The ILI corrosion detection tools assessed in this study are Magnetic Flux Leakage (MFL), Circumferential MFL, Tri-axial MFL, and Ultrasonic Wall Measurement (UT). The corrosion growth rate models considered in this study are single-value corrosion rate model, linear corrosion growth rate model, non-linear corrosion growth rate model, Monte-Carlo method, Markov model, TD-GEVD, TI-GEVD model, Gamma Process, and BMWD model. Strengths and limitations of ILI detection tools, and also corrosion predictive models with some practical examples are discussed. This paper could be useful for those whom are supporting pipeline integrity management and planning. - Highlights: • Different forms of pipeline corrosion are explained. • Common In-Line Inspection (ILI) tools and corrosion growth rate models are introduced. • Strength and limitations of corrosion growth rate models/ILI tools are discussed. • For pipeline integrity management programs using more than one corrosion growth rate model/ILI tool is suggested.

Recent development in low-constraint fracture toughness testing for structural integrity assessment of pipelines

Science.gov (United States)

Kang, Jidong; Gianetto, James A.; Tyson, William R.

2018-03-01

Fracture toughness measurement is an integral part of structural integrity assessment of pipelines. Traditionally, a single-edge-notched bend (SE(B)) specimen with a deep crack is recommended in many existing pipeline structural integrity assessment procedures. Such a test provides high constraint and therefore conservative fracture toughness results. However, for girth welds in service, defects are usually subjected to primarily tensile loading where the constraint is usually much lower than in the three-point bend case. Moreover, there is increasing use of strain-based design of pipelines that allows applied strains above yield. Low-constraint toughness tests represent more realistic loading conditions for girth weld defects, and the corresponding increased toughness can minimize unnecessary conservatism in assessments. In this review, we present recent developments in low-constraint fracture toughness testing, specifically using single-edgenotched tension specimens, SENT or SE(T). We focus our review on the test procedure development and automation, round-robin test results and some common concerns such as the effect of crack tip, crack size monitoring techniques, and testing at low temperatures. Examples are also given of the integration of fracture toughness data from SE(T) tests into structural integrity assessment.

A clustering based method to evaluate soil corrosivity for pipeline external integrity management

International Nuclear Information System (INIS)

Yajima, Ayako; Wang, Hui; Liang, Robert Y.; Castaneda, Homero

2015-01-01

One important category of transportation infrastructure is underground pipelines. Corrosion of these buried pipeline systems may cause pipeline failures with the attendant hazards of property loss and fatalities. Therefore, developing the capability to estimate the soil corrosivity is important for designing and preserving materials and for risk assessment. The deterioration rate of metal is highly influenced by the physicochemical characteristics of a material and the environment of its surroundings. In this study, the field data obtained from the southeast region of Mexico was examined using various data mining techniques to determine the usefulness of these techniques for clustering soil corrosivity level. Specifically, the soil was classified into different corrosivity level clusters by k-means and Gaussian mixture model (GMM). In terms of physical space, GMM shows better separability; therefore, the distributions of the material loss of the buried petroleum pipeline walls were estimated via the empirical density within GMM clusters. The soil corrosivity levels of the clusters were determined based on the medians of metal loss. The proposed clustering method was demonstrated to be capable of classifying the soil into different levels of corrosivity severity. - Highlights: • The clustering approach is applied to the data extracted from a real-life pipeline system. • Soil properties in the right-of-way are analyzed via clustering techniques to assess corrosivity. • GMM is selected as the preferred method for detecting the hidden pattern of in-situ data. • K–W test is performed for significant difference of corrosivity level between clusters

2011-07-01

Full Text Available Abstract Background Contemporary informatics and genomics research require efficient, flexible and robust management of large heterogeneous data, advanced computational tools, powerful visualization, reliable hardware infrastructure, interoperability of computational resources, and detailed data and analysis-protocol provenance. The Pipeline is a client-server distributed computational environment that facilitates the visual graphical construction, execution, monitoring, validation and dissemination of advanced data analysis protocols. Results This paper reports on the applications of the LONI Pipeline environment to address two informatics challenges - graphical management of diverse genomics tools, and the interoperability of informatics software. Specifically, this manuscript presents the concrete details of deploying general informatics suites and individual software tools to new hardware infrastructures, the design, validation and execution of new visual analysis protocols via the Pipeline graphical interface, and integration of diverse informatics tools via the Pipeline eXtensible Markup Language syntax. We demonstrate each of these processes using several established informatics packages (e.g., miBLAST, EMBOSS, mrFAST, GWASS, MAQ, SAMtools, Bowtie for basic local sequence alignment and search, molecular biology data analysis, and genome-wide association studies. These examples demonstrate the power of the Pipeline graphical workflow environment to enable integration of bioinformatics resources which provide a well-defined syntax for dynamic specification of the input/output parameters and the run-time execution controls. Conclusions The LONI Pipeline environment http://pipeline.loni.ucla.edu provides a flexible graphical infrastructure for efficient biomedical computing and distributed informatics research. The interactive Pipeline resource manager enables the utilization and interoperability of diverse types of informatics resources. The

The sound development of marine resource usage relies on a strong maritime engineering industry. The perilous marine environment poses the highest risk to all maritime work. It is therefore imperative to reduce the risk associated with maritime work by using some analytical methods other than engineering techniques. This study addresses this issue by using an integrated interpretive structure modeling (ISM) and Bayesian network (BN) approach in a risk assessment context. Mitigating or managing maritime risk relies primarily on domain expert experience and knowledge. ISM can be used to incorporate expert knowledge in a systematic manner and helps to impose order and direction on complex relationships that exist among system elements. Working with experts, this research used ISM to clearly specify an engineering risk factor relationship represented by a cause–effect diagram, which forms the structure of the BN. The expert subjective judgments were further transformed into a prior and conditional probability set to be embedded in the BN. We used the BN to evaluate the risks of two offshore pipeline projects in Taiwan. The results indicated that the BN can provide explicit risk information to support better project management. - Highlights: • We adopt an integrated method for risk assessment of offshore pipeline projects. • We conduct semi-structural interview with the experts for risk factor identification. • Interpretive structural modeling helps to form the digraph of Bayesian network (BN) • We perform the risk analysis with the experts by building a BN. • Risk evaluations of two case studies using the BN show effectiveness of the methods

Ageing management programme in a plant calls for the estimation of remaining life of the component. Reliability analysis methods using remaining life estimation models have found profound application in providing directives in ageing management programme. As a part of ageing management programme of H 2 S based heavy water plants, the remaining life estimation models are applied to the pipelines carrying H 2 S. The pipelines under H 2 S environment are more susceptible to the internal corrosion thereby reducing the pipeline's load carrying capacity. The objective of this study is to obtain the remaining life of pipelines under ageing due to internal corrosion. The ageing assessment of pipelines involves estimating the failure pressure of a pipeline and evaluating the failure surface equation. Several failure pressure models developed for assessing the pipeline's remaining strength due to internal corrosion were studied for this purpose. From the study, it was found that the modified B31G failure pressure model is most suitable for modeling the pipeline failure pressure. Due to the presence of non-linearity in the failure surface equation or limit state function and non-normal variables, the first order second moment method has been employed for carrying out the reliability analysis. The uncertainties of the random variables on which the limit state function depends are modeled using the probability distributions. The failure probabilities of the pipelines have been evaluated for the service lives of 15 and 25 years, which are the present life and designed life respectively. In addition, sensitivity analysis was carried out to identify the most important sensitive parameters in reliability analysis estimation. The paper highlights the application of these methodologies in the context of pipeline remaining life estimation with a suitable case study. (author)

This document is the distribution integrity management plan (Plan) for the Los Alamos National Laboratory (LANL) Natural Gas Distribution System. This Plan meets the requirements of 49 CFR Part 192, Subpart P Distribution Integrity Management Programs (DIMP) for the LANL Natural Gas Distribution System. This Plan was developed by reviewing records and interviewing LANL personnel. The records consist of the design, construction, operation and maintenance for the LANL Natural Gas Distribution System. The records system for the LANL Natural Gas Distribution System is limited, so the majority of information is based on the judgment of LANL employees; the maintenance crew, the Corrosion Specialist and the Utilities and Infrastructure (UI) Civil Team Leader. The records used in this report are: Pipeline and Hazardous Materials Safety Administration (PHMSA) 7100.1-1, Report of Main and Service Line Inspection, Natural Gas Leak Survey, Gas Leak Response Report, Gas Leak and Repair Report, and Pipe-to-Soil Recordings. The specific elements of knowledge of the infrastructure used to evaluate each threat and prioritize risks are listed in Sections 6 and 7, Threat Evaluation and Risk Prioritization respectively. This Plan addresses additional information needed and a method for gaining that data over time through normal activities. The processes used for the initial assessment of Threat Evaluation and Risk Prioritization are the methods found in the Simple, Handy Risk-based Integrity Management Plan (SHRIMP{trademark}) software package developed by the American Pipeline and Gas Agency (APGA) Security and Integrity Foundation (SIF). SHRIMP{trademark} uses an index model developed by the consultants and advisors of the SIF. Threat assessment is performed using questions developed by the Gas Piping Technology Company (GPTC) as modified and added to by the SHRIMP{trademark} advisors. This Plan is required to be reviewed every 5 years to be continually refined and improved. Records

Pipeline integrity evaluation of oil pipelines using free-swimming acoustic technology

Ariaratnam, Samuel T. [Arizona State University, Tempe, Arizona (United States); Chandrasekaran, Muthu [Pure Technologies Limited, Calgary, AB (Canada)

2010-07-01

In the United States, the Pipeline and Hazardous Materials Safety Administration (PHMSA) funded a joint academy-industry research project, which developed and refined a free-swimming tool called SmartBall. The tool swims through the pipeline and gives results at a much lower cost than current leak detection methods, and it can detect leaks as small as 0.03 gpm of oil. GPS-synchronized above-ground loggers capture acoustic signals and record the passage of the tool through the pipeline. The tool is spherical and smaller than the pipe, through which it rolls silently; it can overcome obstacles that could otherwise make a pipeline unpiggable. SmartBall uses the great potential of acoustic detection, because when a pressurized product leaks from a pipe, it produces a distinctive acoustic signal that travels through the product; at the same time, it overcomes the problem caused by the very limited range of this signal. This technology can prevent enormous economic consequences such as a 50,000-gallon gasoline spill that happened in 2003 between Tucson and Phoenix.

Internal corrosion control of northern pipelines

Energy Technology Data Exchange (ETDEWEB)

Papavinasam, S.

2005-02-01

The general causes of internal corrosion in pipelines were discussed along with the methods to control them. Efficient methods are needed to determine chemical efficiency for mitigating internal corrosion in transmission pipelines, particularly those used in environmentally sensitive regions in the Arctic where harsh environmental conditions prevail. According to the Office of Pipeline Safety, 15 per cent of pipeline failures in the United States from 1994 to 2000 were caused by internal corrosion. Since pipelines in the United States are slightly older than Canadian pipelines, internal corrosion is a significant issue from a Canadian perspective. There are 306,618 km of energy-related pipelines in western Canada. Between April 2001 and March 2002 there were 808 failures, of which 425 failures resulted from internal corrosion. The approach to control internal corrosion comprises of dehydrating the gases at production facilities; controlling the quality of corrosive gases such as carbon dioxide and hydrogen sulphide; and, using internal coatings. The approaches to control internal corrosion are appropriate, when supplemented by adequate integrity management program to ensure that corrosive liquids do not collect, over the operational lifetime of the pipelines, at localized areas. It was suggested that modeling of pipeline operations may need improvement. This paper described the causes, prediction and control of internal pitting corrosion. It was concluded that carbon steel equipment can continue to be used reliably and safely as pipeline materials for northern pipelines if the causes that lead to internal corrosion are scientifically and accurately predicted, and if corrosion inhibitors are properly evaluated and applied. 5 figs.

Modeling and Calculation of Dent Based on Pipeline Bending Strain

Directory of Open Access Journals (Sweden)

Qingshan Feng

2016-01-01

Full Text Available The bending strain of long-distance oil and gas pipelines can be calculated by the in-line inspection tool which used inertial measurement unit (IMU. The bending strain is used to evaluate the strain and displacement of the pipeline. During the bending strain inspection, the dent existing in the pipeline can affect the bending strain data as well. This paper presents a novel method to model and calculate the pipeline dent based on the bending strain. The technique takes inertial mapping data from in-line inspection and calculates depth of dent in the pipeline using Bayesian statistical theory and neural network. To verify accuracy of the proposed method, an in-line inspection tool is used to inspect pipeline to gather data. The calculation of dent shows the method is accurate for the dent, and the mean relative error is 2.44%. The new method provides not only strain of the pipeline dent but also the depth of dent. It is more benefit for integrity management of pipeline for the safety of the pipeline.

A method of quantitative risk assessment for transmission pipeline carrying natural gas

Jo, Young-Do; Ahn, Bum Jong

2005-01-01

Regulatory authorities in many countries are moving away from prescriptive approaches for keeping natural gas pipelines safe. As an alternative, risk management based on a quantitative assessment is being considered to improve the level of safety. This paper focuses on the development of a simplified method for the quantitative risk assessment for natural gas pipelines and introduces parameters of fatal length and cumulative fatal length. The fatal length is defined as the integrated fatality along the pipeline associated with hypothetical accidents. The cumulative fatal length is defined as the section of pipeline in which an accident leads to N or more fatalities. These parameters can be estimated easily by using the information of pipeline geometry and population density of a Geographic Information Systems (GIS). To demonstrate the proposed method, individual and societal risks for a sample pipeline have been estimated from the historical data of European Gas Pipeline Incident Data Group and BG Transco. With currently acceptable criteria taken into account for individual risk, the minimum proximity of the pipeline to occupied buildings is approximately proportional to the square root of the operating pressure of the pipeline. The proposed method of quantitative risk assessment may be useful for risk management during the planning and building stages of a new pipeline, and modification of a buried pipeline

The objective of this study consisted in investigating the possible causes which give rise to the presence of low wall pipe thicknesses on a 16'' natural gas transport pipeline, even though during the last 12-year period cathodic protection (CP) potentials were kept in the protection range at which external corrosion should not occur. Results from in-line inspection from a 16'' natural gas transport pipeline showed 46 indications with more than 80% wall thickness lost due to external corrosion in the second segment of the pipeline. Direct inspection at the indication locations, review of the CP system performance, pipeline maintenance programs and studies, allowed to make an integral diagnostic where it was found out that the main cause of external corrosion was an inappropriate coating application since the pipeline construction, this situation has originated the increase of CP shielding effects through time.

Pipeline risk management has been stimulated by pipeline ruptures throughout the world. This paper explores risk management and mitigation strategies for minimizing consequences from pipeline releases, and optimizing financial resources in response or in prevention of these events. More specifically, it examines private sector innovations which optimize mitigation activities in combination with public sector programs such as regulations and standards (i.e., ASME B31.S, API 1160). The mitigation of risk involves the implementation of measures to reduce the frequency of failure, the severity of consequences, or both these attributes of risk. A wide variety of risk mitigation measures are available to pipeline operators. Given the diversity of mitigation measures available, this paper proposes a framework that can assist operating companies in selecting risk mitigation strategies based on risk results, mitigation costs and benefits.

2009-12-19

The pressure to get engineering projects done and constructed as fast as possible in order to take advantage of the high prices in metals and petrochemicals has been driving companies to skip the conceptual phase and go straight into basic engineering with cost estimates in the level of 15% accuracy. By-passing early engineering and demanding higher cost estimating accuracy is a contradiction. In most cases, savings made on capital investment is much higher had money been spent in conceptual studies which allow for the optimal solution to be found. This paper reviews one of the key aspects in conceptual engineering of slurry pipeline designs: route selection. This activity is often overlooked, causing capital cost and operating difficulties to rise unnecessarily. This paper describes and gives example on how an integrated client/engineering company's approach to route selection can produce significant savings in pipeline construction and operating costs.

The check valve slam results in a water hammer and unexpected system pressure rise in the pipeline. Sometimes, the pressure rise by check valve slam in the pipeline exceeds the design pressure and then it causes the rupture of pipeline. Therefore, check valve slam significantly influences on the integrity of pipe. Especially, this it is most likely to occur by check valve installed in the discharge of pump when one pump trips among the two or more running in parallel pump system. This study focuses on the check valve selection to maintain the integrity of PCS pipeline against the check valve slam. If design head for KJRR PCS pipeline is higher than the sum of static head and 11 m, any type check valves can be installed at the discharge of pump. However, if design head for KJRR PCS pipeline is lower than the sum of static head and 11 m, installation of swing and ball check on the discharge of pump must be avoid to prevent the rupture of PCS pipeline.

Sayed, A.M.; Jaffery, M.A.

2005-01-01

Pipe forms an integral part of transmission medium in oil and gas industry. This holds true for both upstream and downstream segments of this global energy business. With the aging of this asset base, emphasis on its operational aspects has been under immense considerations from the operators and regulators sides. Moreover, the milieu of information area and enhancement in global trade has lifted the barriers on means to forge forward towards better utilization of resources. This has resulted in optimized solutions as priority for business and technical manager's world over. There is a paradigm shift from mere development of 'smart materials' to 'low life cycle cost material'. The force inducing this change is a rationale one: the recovery of development costs is no more a problem in a global community; rather it is the pay-off time which matters most to the materials end users. This means that decision makers are not evaluating just the price offered but are keen to judge the entire life cycle cost of a product. The integrity of pipe are affected by factors such as corrosion, fatigue-crack growth, stress-corrosion cracking, and mechanical damage. Extensive research in the area of reliability and life assessment has been carried out. A number of models concerning with the reliability issues of pipes have been developed and are being used by a number of pipeline operators worldwide. Yet, it is emphasised that there are no substitute for sound engineering judgment and allowance for factors of safety. The ability of a laid down pipe network to transport the intended fluid under pre-defined conditions for the entire project envisaged life, is referred to the reliability of system. The reliability is built into the product through extensive benchmarking against industry standard codes. The process of pipes construction for oil and gas service is regulated through American Petroleum Institute's Specification for Line Pipe. Subsequently, specific programs have been

When managing pipeline integrity, the quality of inspection information is critical to determining the true condition of the pipeline, and predicting its future condition over time. The cost of a pipeline failure is nearly always much more than the cost of using a quality inspection service to obtain accurate information on the condition of the line. With pressure to reduce costs for all services, the focus often falls on the two most visible areas, tool selection and short-term service cost. These are important factors, but what is equally important is the quality and reliability of the data obtained and its effect on pipeline integrity. Without reliable data our information on pipeline condition is uncertain at best. These issues of data quality are often not well understood since many specialist technical factors are involved. This paper highlights some of the issues that need to be considered so that their importance and the effort that goes into them can be appreciated better. At the end of the day, the prime requirement is a safe, accurate and reliable inspection, delivering a good specification over a wide range of pipeline conditions and flow velocities. (author)

Wastewater pipeline leakage is an emerging concern in Europe, especially with regards to the potential effect of leaking effluent on groundwater contamination and the effects infiltration has on the management of sewer reticulation systems. This paper describes efforts by Australia, in association with several European partners, towards the development of decision support tools to prioritize proactive rehabilitation of wastewater pipe networks to account for leakage. In the fundamental models for the decision support system, leakage is viewed as a function of pipeline system deterioration. The models rely on soil type identification across the service area to determine the aggressiveness of the pipe environment and for division of the area into zones based on pipe properties and operational conditions. By understanding the interaction between pipe materials, operating conditions, and the pipe environment in the mechanisms leading to pipe deterioration, the models allow the prediction of leakage rates in different zones across a network. The decision support system utilizes these models to predict the condition of pipes in individual zones, and to optimize the utilization of rehabilitation resources by targeting the areas with the highest leakage rates.

Our city has owned the integrated pipeline network management system with ArcGIS Engine 9.1 as the bottom development platform and with Oracle9i as basic database for storaging data. In this system, ArcGIS SDE9.1 is applied as the spatial data engine, and the system was a synthetic management software developed with Visual Studio visualization procedures development tools. As the pipeline update function of the system has the phenomenon of slower update and even sometimes the data lost, to ensure the underground pipeline data can real-time be updated conveniently and frequently, and the actuality and integrity of the underground pipeline data, we have increased a new update module in the system developed and researched by ourselves. The module has the powerful data update function, and can realize the function of inputting and outputting and rapid update volume of data. The new developed module adopts Visual Studio visualization procedures development tools, and uses access as the basic database to storage data. We can edit the graphics in AutoCAD software, and realize the database update using link between the graphics and the system. Practice shows that the update module has good compatibility with the original system, reliable and high update efficient of the database.

Managing changes of location classes of gas pipelines

Energy Technology Data Exchange (ETDEWEB)

Cunha, Sergio B; Sousa, Antonio Geraldo de [PETROBRAS Transporte S.A. (TRANSPETRO), Rio de Janeiro, RJ (Brazil)

2009-12-19

Most of the gas pipeline design codes utilize a class location system, where the design safety factor and the hydrostatic test factor are determined according to the population density in the vicinities of the pipeline route. Consequently, if an operator is requested or desires to maintain an existing gas pipeline in compliance with its design code, it will reduce the operational pressure or replace pipe sections to increase the wall thickness whenever a change in location class takes place. This article introduces an alternative methodology to deal with changes in location classes of gas pipelines. Initially, selected codes that utilize location class systems are reviewed. Afterwards, a model for the area affected by an ignition following a natural gas pipeline leak is described. Finally, a methodology to determine the MAOP and third part damage mitigation measures for gas transport pipelines that underwent changes in location class is presented. (author)

For upgrading long-term integrity of transmission pipelines, two types of delayed fracture in regions of mechanical damage in pipelines were investigated. Experimental and numerical studies clarified factors affecting the fatigue behavior of line pipes containing an idealized flaw under fluctuating internal pressure. To investigate fatigue cracking at mechanical damage in pipelines, degradation of fracture toughness and fatigue properties due to plastic pre-strain was also evaluated. A fracture mechanics-based study revealed conditions necessarily for initiation of hydrogen stress cracking (HSC) at a surface defect in line pipes under cathodic protection. (authors)

As oil and gas production continues to move into new frontier areas, novel applications of the existing riser and pipeline technologies need to be developed to meet the often more stringent requirements encountered in these environments. The challenges include ultra deep water, harsh environments, aggressive fluid conditions, and local content objectives, etc. They will require industry to constantly extend, expand, and enhance the broad range of solution options. Also, the existing design criteria in industry may need to be revised or new criteria may need to be developed to satisfy these needs. Exxon Mobil (Em) employs, and works with others in industry to promote robust design and operating practices. This approach requires in-depth understanding, sound engineering principles, advanced analysis, uncertainty management, and supportive qualification test data. It enables confident selection, extrapolation, and innovation of technologies to address new riser system and pipeline challenges. Focus on fundamental is imperative to ensure integrity of the selected systems during fabrication, installation, and operation phases. Recent and past project experience in deep water Gulf of Mexico and West Africa provides many successful examples of this approach. This paper reviews several examples of the key riser system and pipeline technology enhancements recently achieved by EM to provide confidence in addressing technical and project application challenges. Riser system technology enhancements addressed in this paper include steel catenary riser (SCR) application on turret-moored FPSO with severe motions, pipe-in-pipe (PIP) hybrid production riser to effectively manage gas lift and flow assurance requirements, irregular wave analysis methodology for flexible risers and umbilicals to reduce conservatism, and qualification of riser and pipeline VIV prediction and mitigation methods. Pipeline technology enhancements detailed in this paper include lateral buckling prediction

2009-07-01

A large scale risk assessment was performed by Det Norske Veritas (DNV) for the entire Kuwait Oil Company (KOC) pipeline network. This risk assessment was unique in that it incorporated the assessment of all major sources of process related risk faced by KOC and included root cause management system related risks in addition to technical risks related to more immediate causes. The assessment was conducted across the entire pipeline network with the scope divided into three major categories:1. Integrity Management 2. Operations 3. Management Systems Aspects of integrity management were ranked and prioritized using a custom algorithm based on critical data sets. A detailed quantitative risk assessment was then used to further evaluate those issues deemed unacceptable, and finally a cost benefit analysis approach was used to compare and select improvement options. The operations assessment involved computer modeling of the entire pipeline network to assess for bottlenecks, surge and erosion analysis, and to identify opportunities within the network that could potentially lead to increased production. The management system assessment was performed by conducting a gap analysis on the existing system and by prioritizing those improvement actions that best aligned with KOC's strategic goals for pipelines. Using a broad and three-pronged approach to their overall risk assessment, KOC achieved a thorough, root cause analysis-based understanding of risks to their system as well as a detailed list of recommended remediation measures that were merged into a 5-year improvement plan.

Environmental audit guidelines for pipelines

International Nuclear Information System (INIS)

1991-01-01

Environmental auditing is a form of management control which provides an objective basis by which a company can measure the degree of compliance with environmental regulations. Other benefits of this type of auditing include improved environmental management, furthering communication on environmental issues of concern within the company, and provision of documentation on environmental diligence. A series of environmental audit guidelines for pipelines is presented in the form of lists of questions to be asked during an environmental audit followed by recommended actions in response to those questions. The questions are organized into seven main categories: environmental management and planning; operating procedures; spill prevention; management of wastes and hazardous materials; environmental monitoring; construction of pipelines; and pipeline abandonment, decommissioning and site reclamation

Working Group 10 presented experiences acquired from the operation of pipeline systems in a northern environment. There are currently 3 pipelines operating north of 60, notably the Shiha gas pipeline near Fort Liard, the Ikhil gas pipeline in Inuvik and the Norman Wells oil pipeline. Each has its unique commissioning, operating and maintenance challenges, as well as specific training and logistical support requirements for the use of in-line inspection tools and other forms of integrity assessment. The effectiveness of cathodic protection systems in a permafrost northern environment was also discussed. It was noted that the delay of the Mackenzie Gas Pipeline Project by two to three years due to joint regulatory review may lead to resource constraints for the project as well as competition for already scarce human resources. The issue of a potential timing conflict with the Alaskan Pipeline Project was also addressed as well as land use issues for routing of supply roads. Integrity monitoring and assessment issues were outlined with reference to pipe soil interaction monitoring in discontinuous permafrost; south facing denuded slope stability; base lining projects; and reclamation issues. It was noted that automatic welding and inspection will increase productivity, while reducing the need for manual labour. In response to anticipated training needs, companies are planning to involve and train Aboriginal labour and will provide camp living conditions that will attract labour. tabs., figs.

Application of risk based inspection methodology of API 581 BRD to oil pipelines

In response to public concerns regarding the safe operation of pipelines, operators are relying on risk management to balance the demands of pipeline integrity and service competitiveness. This paper presented a procedure for calculating the probability of failure according to the API 581 BRD RB I methodology that uses data collected from 3 existing oil pipelines subject to internal corrosion. The risk exposure that the pipeline may be subjected to during its remaining operating life was evaluated. Risk is a function of the probability of failure and the consequences of that failure. Therefore, if the consequences of the failure are assumed to remain unchanged for a given equipment under specific operational conditions, then risk reduction will only be achieved by decreasing the probability of failure and through management of the inspection process. It was shown that if the confidence on the damage rate and on the inspection effectiveness is known, then it is possible to design an alternative to an existing inspection plan. This calls for pig inspections at 5 year intervals to ensure that the probability of failures for pipelines will be under a certain level of tolerable risk. 9 refs., 4 tabs., 3 figs.

Using geospatial solutions to meet distribution integrity management requirements

In the United States, incidents on gas distribution pipelines kill on average 10 persons per year in addition to causing 40 serious injuries and millions of dollars of property damage. In order to remedy to this situation, the US Department of Transportation/Pipeline Hazardous Materials Safety Administration enacted new regulations requiring operators to develop distribution integrity management programs (DIMP) which must include: knowledge and identification of threats, evaluation of risk, identification and implementation of measures to address risks, performance measuring, periodic evaluation and improvement and results reporting. The aim of this paper is to show how geographic information systems (GIS) can help operators meet each requirement of the DIMP regulations. This discussion showed that GIS can help in identifying and quantifying the threats to the distribution system and in assessing the consequences of an incident. Investing in GIS will not only help operators in complying with the regulations but will also help them make economically sound, risk-based decisions.

INVESTIGATION OF PIPELINES INTEGRITY ASSOCIATED WITH PUMP MODULES VIBRATION FOR PUMPING STATION 9 OF ALYESKA PIPELINE SERVICE COMPANY

Since the operation of PS09 SR module in 2007, it has been observed that there is vibration in various parts of the structures, on various segments of piping, and on appurtenance items. At DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) request, ORNL Subject Matter Experts support PHMSA in its review and analysis of the observed vibration phenomenon. The review and analysis consider possible effects of pipeline design features, vibration characteristics, machinery configuration, and operating practices on the structural capacity and leak tight integrity of the pipeline. Emphasis is placed on protection of welded joints and machinery against failure from cyclic loading. A series of vibration measurements were carried out by the author during the site visit to PS09, the power of the operating pump during the data collection is at about 2970KW, which is less than that of APSC's vibration data collected at 3900KW. Thus, a first order proportional factor of 4900/2970 was used to project the measured velocity data to that of APSC's measurement of the velocity data. It is also noted here that the average or the peak-hold value of the measured velocity data was used in the author's reported data, and only the maximum peak-hold data was used in APSC's reported data. Therefore, in some cases APSC's data is higher than the author's projective estimates that using the average data. In general the projected velocity data are consistent with APSC's measurements; the examples of comparison at various locations are illustrated in the Table 1. This exercise validates and confirms the report vibration data stated in APSC's summary report. After the reinforcement project for PS09 Station, a significant reduction of vibration intensity was observed for the associated pipelines at the SR Modules. EDI Co. provided a detailed vibration intensity investigation for the newly reinforced Pump Module structures and the associated

Next generation sequencing technologies have revolutionized our ability to rapidly and affordably generate vast quantities of sequence data. Once generated, raw sequences are assembled into contigs or scaffolds. However, these assemblies are mostly fragmented and inaccurate at the whole genome scale, largely due to the inability to integrate additional informative datasets (e.g. physical, optical and genetic maps). To address this problem, we developed a semi-automated software tool-Genome Puzzle Master (GPM)-that enables the integration of additional genomic signposts to edit and build 'new-gen-assemblies' that result in high-quality 'annotation-ready' pseudomolecules. With GPM, loaded datasets can be connected to each other via their logical relationships which accomplishes tasks to 'group,' 'merge,' 'order and orient' sequences in a draft assembly. Manual editing can also be performed with a user-friendly graphical interface. Final pseudomolecules reflect a user's total data package and are available for long-term project management. GPM is a web-based pipeline and an important part of a Laboratory Information Management System (LIMS) which can be easily deployed on local servers for any genome research laboratory. The GPM (with LIMS) package is available at https://github.com/Jianwei-Zhang/LIMS CONTACTS: jzhang@mail.hzau.edu.cn or rwing@mail.arizona.eduSupplementary information: Supplementary data are available at Bioinformatics online. © The Author 2016.

Full Text Available Abstract Background Modern omics research involves the application of high-throughput technologies that generate vast volumes of data. These data need to be pre-processed, analyzed and integrated with existing knowledge through the use of diverse sets of software tools, models and databases. The analyses are often interdependent and chained together to form complex workflows or pipelines. Given the volume of the data used and the multitude of computational resources available, specialized pipeline software is required to make high-throughput analysis of large-scale omics datasets feasible. Results We have developed a generic pipeline system called Cyrille2. The system is modular in design and consists of three functionally distinct parts: 1 a web based, graphical user interface (GUI that enables a pipeline operator to manage the system; 2 the Scheduler, which forms the functional core of the system and which tracks what data enters the system and determines what jobs must be scheduled for execution, and; 3 the Executor, which searches for scheduled jobs and executes these on a compute cluster. Conclusion The Cyrille2 system is an extensible, modular system, implementing the stated requirements. Cyrille2 enables easy creation and execution of high throughput, flexible bioinformatics pipelines.

In the last decade several industries (oil and gas pipelines, nuclear power, and municipal water) have experienced an increase in the frequency and public scrutiny of leaks and failures associated with buried piping and tank assets. In several industries, regulatory pressure has resulted in the mandated need for databases and inspection programs to document and ensure the continued integrity of these assets. Power plants are being extended beyond their design life and the condition of below grade assets is essential toward continued operation. This article shares the latest advances in managing design, operation, process, inspection, and historical data for power plant piping. Applications have also been developed to help with risk prioritization, inspection method selection, managing cathodic protection data for external corrosion control, and a wide variety of other information. This data can be managed in a GIS environment allowing two and three dimensional (2D and 3D) access to the database information. (orig.)

There are two underlying trends in the expansion of omics informatics landscape: the explosion of scattered individual omics informatics tools with each of which focuses on a specific task in both single- and multi- omic settings, and the fast-evolving integrated software platforms such as workflow management systems that can assemble multiple tools into pipelines and streamline integrative analysis for complicated tasks. In this survey, we give a holistic view of omics informatics, from scattered individual informatics tools to integrated workflow management systems. We not only outline the landscape and challenges of omics informatics, but also sample a number of widely used and cutting-edge algorithms in omics data analysis to give readers a fine-grained view. We survey various workflow management systems (WMSs), classify them into three levels of WMSs from simple software toolkits to integrated multi-omic analytical platforms, and point out the emerging needs for developing intelligent workflow management systems. We also discuss the challenges, strategies and some existing work in systematic evaluation of omics informatics tools. We conclude by providing future perspectives of emerging fields and new frontiers in omics informatics.

Integrity management and optimization of planning activities from results of the ILI run

Transierra owns and operates the Yacuiba - Rio Grande pipeline (GASYRG), 432 kilometers in length and 32 inches in diameter, which transports natural gas from the fields of San Alberto and San Antonio (southern Bolivia) to the Rio Grande compression station (Santa Cruz), and is part of the gas export system to Brazil. This pipeline system has a sustained capacity to transport 17,6 million of cubic meter per day. Within the Integrity Management Program (IMP) has been developing and implementing activities and techniques that seeking to ensure the technical integrity of the pipeline, from the good practices of the industry, which also get an optimization for the use of resources for inspection, operation and maintenance activities. In response to that goal at the beginning of 2008, it was concluded the baseline of the GASYRG ILI runs, getting a very good stage of both the internal and external condition of the pipeline, found some stables anomalies (manufacturing and construction) which do not affect the safe operation status of the pipeline, in this way, it was appropriate to re-planning the maintenance programs of all facilities and main elements, in order to achieve a balance between safety operation condition of the pipeline and the resources used for these purposes, which means that there is a 'before' and an 'after' regarding to planning and maintenance activities are concerned. All of this re-planning gives us a cost optimization for the main activities in the order of 30%. Additionally there has been a very particular approach to care for and prevent threats related to corrosion, maintaining a stable cathodic protection system, taking into account the presence of interfering elements (crossing with pipelines, power lines, railroads, etc.). Also important steps have been taken regarding to the changing dynamic to the action of third parties, it is part of a specific program for strengthening contingency plans. Concluding the above, the

The function and design of pipelines for use on the United Kingdom continental shelf are described. Environmental influences which can threaten the integrity of seabed pipelines in the North Sea include hydrodynamic forces due to residual, tidal and wave currents, the nature of seabed sediments and corrosion by seawater. Damage may be caused to pipelines by interaction with vessel anchors and with fishing gear. Special care has to be taken over the selection of the general area for the landfall of a pipeline and the engineering of the installation where the pipeline comes ashore. Trenching and other protection techniques for pipelines are discussed together with hydrostatic testing and commissioning and subsequent inspection, maintenance and repair. (UK)

Reliability-based management of buried pipelines considering external corrosion defects

Science.gov (United States)

Miran, Seyedeh Azadeh

Corrosion is one of the main deteriorating mechanisms that degrade the energy pipeline integrity, due to transferring corrosive fluid or gas and interacting with corrosive environment. Corrosion defects are usually detected by periodical inspections using in-line inspection (ILI) methods. In order to ensure pipeline safety, this study develops a cost-effective maintenance strategy that consists of three aspects: corrosion growth model development using ILI data, time-dependent performance evaluation, and optimal inspection interval determination. In particular, the proposed study is applied to a cathodic protected buried steel pipeline located in Mexico. First, time-dependent power-law formulation is adopted to probabilistically characterize growth of the maximum depth and length of the external corrosion defects. Dependency between defect depth and length are considered in the model development and generation of the corrosion defects over time is characterized by the homogenous Poisson process. The growth models unknown parameters are evaluated based on the ILI data through the Bayesian updating method with Markov Chain Monte Carlo (MCMC) simulation technique. The proposed corrosion growth models can be used when either matched or non-matched defects are available, and have ability to consider newly generated defects since last inspection. Results of this part of study show that both depth and length growth models can predict damage quantities reasonably well and a strong correlation between defect depth and length is found. Next, time-dependent system failure probabilities are evaluated using developed corrosion growth models considering prevailing uncertainties where three failure modes, namely small leak, large leak and rupture are considered. Performance of the pipeline is evaluated through failure probability per km (or called a sub-system) where each subsystem is considered as a series system of detected and newly generated defects within that sub

Integration of Absolute Orientation Measurements in the KinectFusion Reconstruction pipeline

KAUST Repository

Giancola, Silvio

2018-02-12

In this paper, we show how absolute orientation measurements provided by low-cost but high-fidelity IMU sensors can be integrated into the KinectFusion pipeline. We show that integration improves both runtime, robustness and quality of the 3D reconstruction. In particular, we use this orientation data to seed and regularize the ICP registration technique. We also present a technique to filter the pairs of 3D matched points based on the distribution of their distances. This filter is implemented efficiently on the GPU. Estimating the distribution of the distances helps control the number of iterations necessary for the convergence of the ICP algorithm. Finally, we show experimental results that highlight improvements in robustness, a speed-up of almost 12%, and a gain in tracking quality of 53% for the ATE metric on the Freiburg benchmark.

This paper regards to the concerning that the pipeline operators should take in to account to better understand and control the alternate current interference (AC- interference). Pipelines sharing rights-of-way with AC high voltage power lines are subjected to AC interference that can cause risk for personnel, operational safety and environment. The AC-interference shall be evaluated, in such way that mitigating action can be applied in order to assure the pipeline is operated in a safety way. The AC-interference evaluation should take in to account the pipeline and the electrical generation/transmission design data. Three approaches are considered: the coating integrity, the personnel chock hazards and the pipeline integrity. The coating integrity is affected by the possibility of high-voltage be induced on the pipeline during power line current fault. The operation and maintenance personnel can be prone to chock hazards (touch voltage and step voltage), depending upon the level of the induced voltage on the pipeline and the ground current. An induced voltage evaluation is then necessary to identify AC potentials in pipeline higher than the safe criteria. The pipeline integrity is concerning to the possibility of occurring alternate current corrosion (AC-corrosion) on the pipe wall. This kind of corrosion is still been investigated, and although it is less critical than the direct current corrosion, it can happen in specific situation. Parameters that affect AC-corrosion are discussed in this paper. Finely it is presented a brief guide to evaluate the possibility of occurring AC- interference in a pipeline and a mitigation measures summary. (author)

There are several methods for the risk assessment and risk management applied to pipelines, among them the Muhlbauer's Method. W. Kent Muhlbauer is an internationally recognized authority on pipeline risk management. He made a detailed identification about 300 distinct conditions that influence the risk assessment in pipelines and he proposed a score system that is known as method of Muhlbauer. The purpose of this model is to evaluate the public exposure to the risk and identify ways for management that risk in fact. The assessment is made by the attribution of quantitative values to the several items that influences in the pipeline risk. This paper approaches the Muhlbauer's basic model for risk assessment and management in pipelines. In the beginning, the basic model for risk assessment is presented, and methodology for pipelines in onshore environment is detailed. After, presents major items in risk assessment and this relative score. Finally, present the additional modules for Muhlbauer's method customizing. (author)

Full Text Available Purpose of the study: The purpose this paper is to identify and describe the characteristics and influences of the cotton farming pipeline in Malawi and South Africa. Problem investigated: A broad based approach was followed to investigate the cotton farming pipeline to identify the major driving forces of the cotton pipeline in each of the respective countries. Research approach: A qualitative field research approach was followed to compile data on cotton farming in Malawi and South Africa. Data was compiled upstream from input suppliers, downstream from ginners, cotton transport conveyors, cotton marketing managers and agricultural government officials as well as from farmers and agricultural organizations. Findings: In Malawi a family farming model is followed versus an industrial model of production in South Africa. Despite the differences in approach, the farmers in both countries are faced with similar problems. In this regard, an urgent rethinking of the technological conditions of production and the possibilities of technological change is needed. Recommendations: The research proposes that these countries can benefit from establishing institutions like agricultural co-operatives and mechanisms like the development of a free traffic mechanism of seed-cotton. Conclusion: The present research may assist in developing first layer managerial recommendations that could enhance the sustainability and co-existence of cotton farming in the two countries.

Lowering the rate of water leakage from the network of underground pipes is one of the requirements that "smart" cities have to comply with. In fact, losses in the water supply infrastructure have a remarkable social, environmental and economic impact, which obviously conflicts with the expected efficiency and sustainability of a smart city. As a consequence, there is a huge interest in developing prevention policies based on state-of-art sensing techniques and possibly their integration, as well as in envisaging ad hoc technical solutions designed for the application at hand. As a contribution to this framework, in this communication we present an approach aimed to pursue a thorough non-invasive monitoring of water pipelines, with both high spatial and temporal resolution. This goal is necessary to guarantee that maintenance operations are performed timely, so to reduce the extent of the leakage and its possible side effects, and precisely, so to minimize the cost and the discomfort resulting from operating on the water supply network. The proposed approach integrates two sensing techniques that work at different spatial and temporal scales. The first one is meant to provide a continuous (in both space and time) monitoring of the pipeline and exploits a distributed optic fiber sensor based on the Brillouin scattering phenomenon. This technique provides the "low" spatial resolution information (at meter scale) needed to reveal the presence of a leak and call for interventions [1]. The second technique is based on the use of Ground Penetrating Radar (GPR) and is meant to provide detailed images of area where the damage has been detected. GPR systems equipped with suitable data processing strategies [2,3] are indeed capable of providing images of the shallow underground, where the pipes would be buried, characterized by a spatial resolution in the order of a few centimeters. This capability is crucial to address in the most proper way maintenance operations, by for

SimVascular (www.simvascular.org) is currently the only fully open source software package that provides a complete pipeline from medical image based modeling to patient specific blood flow simulation and analysis. It was initially released in 2007 and has contributed to numerous advances in fundamental hemodynamics research, surgical planning, and medical device design. However, early versions had several major barriers preventing wider adoption by new users, large-scale application in clinical and research studies, and educational access. In the past years, SimVascular 2.0 has made significant progress by integrating open source alternatives for the expensive commercial libraries previously required for anatomic modeling, mesh generation and the linear solver. In addition, it simplified the across-platform compilation process, improved the graphical user interface and launched a comprehensive documentation website. Many enhancements and new features have been incorporated for the whole pipeline, such as 3-D segmentation, Boolean operation for discrete triangulated surfaces, and multi-scale coupling for closed loop boundary conditions. In this presentation we will briefly overview the modeling/simulation pipeline and advances of the new SimVascular 2.0.

The optimization of pipeline transportation is a big concern for the transporter companies. This paper is the third of a series of three articles which investigated the application of a system to simulate the human ability to operate a pipeline in an optimized way. The present paper presents the development of a proportional integral (PI) fuzzy controller, in order to optimize pipeline transportation capacity. The fuzzy adaptive PI controller system was developed and tested with a hydraulic simulator. On-field data were used from the OSBRA pipeline. The preliminary tests showed that the performance of the software simulation was satisfactory. It varied the set-point of the conventional controller within the limits of flow meters. The transport capacity of the pipe was maximize without compromising the integrity of the commodities transported. The system developed proved that it can be easily deployed as a specialist optimizing system to be added to SCADA systems.

The study and modeling of corrosion processes aim at the accomplishment of three primary objectives: to increase safety operation margins, to reduce maintenance costs and to optimize available resources. The Integrity Expert System is based on a statistical propagation model of defects reported by high resolution magnetic inspection tool (MFL), fed with the information provided by corrosion sensors, repair interventions, field surveys and future inspections. As model results, defect depth, remaining strength and failure probability distributions were obtained. From the analysis, feasible courses of action were established: a medium term repair plan, an internal inspection program and both monitoring and mitigation technologies. System implementation in OLDELVAL was translated into two major effects of importance for the company integrity program: reduction in the pipeline probability of failure by corrosion by means of programmed repairs and optimization of the internal inspection investment plan by mans of an alternative programming.

Grasping at Straws: Comments on the Alberta Pipeline Safety Review

Directory of Open Access Journals (Sweden)

Jennifer Winter

2013-09-01

Full Text Available The release last month of the Alberta Pipeline Safety Review was meant to be a symbol of the province’s renewed commitment to environmental responsibility as it aims for new export markets. The report’s authors, Group 10 Engineering, submitted 17 recommendations covering public safety and pipeline incidents, pipeline integrity management and pipeline safety near bodies of water — and many of them run the gamut from the obvious to the unhelpful to the contradictory. That the energy regulator ought to be staffed to do its job should go without saying; in fact, staffing levels were never identified as an issue. The recommendation that record retention and transfer requirements be defined for mergers and acquisitions, sales and takeovers is moot. There is no reason a purchasing party would not want all relevant documents, and no real way to enforce transparency if the seller opts to withhold information. Harmonizing regulations between provinces could reduce companies’ cost of doing business, but could also prove challenging if different jurisdictions use performance-based regulations — which is what the Review recommended Alberta consider. This very brief paper pries apart the Review’s flaws and recommends that the province go back to the drawing board. Safety is a serious issue; a genuine statistical review linking pipeline characteristics to failures and risk-mitigation activities would be a better alternative by far.

2003-07-01

In today's pipeline environment, operators around the world face new and emerging state and federal regulations requiring validation of their pipelines' integrity. In line inspection, or smart pigging, is generally the preferred methodology used to investigate metal loss and corrosion in pipelines. Although many pipelines can accommodate smart pigging, there are many pipelines that cannot, for various reasons. Those reasons can vary from not having pig launchers and receivers installed on the line to impassable bends or restrictions and general cleanliness of the pipeline itself. Pipeline cleanliness, more times than not, is one of the main reasons for inaccurate in line inspection data gathering or failed smart pig runs. (author)

Usually pipelines construction are located in isolated places which are difficult to access. Due this characteristic the logistical support services are not available as easily as it is in large centers. Even so these enterprises may not release these services mainly due to high demand from stakeholders and the commitment to quality that these pipelines are submitted. This work presents some alternatives in environmental management implemented during an installation of pipelines in the Amazon forest with emphasis on the quality of water bodies and correct effluents destination. Located in western Amazonia in a region with several restrictions like: logistics, low supply of skilled labor and high environmental requirements. The project aligned competence and creativity since from its planning until its delivery to overcome difficulties and meet the demands of stakeholders. Usual techniques to assist legal requirements such as effluent treatment and environmental monitoring had to be adapted to the Amazon reality, always seeking for balance between technical and alignment economic and respect for social and environmental aspects. Using the methodology of 'wetland' (system of alternative treatment of effluents, based on the use of regional plants - macrophytes), the reuse of sludge from sewage treatment station, floating sewage treatment system, was crucial to meet the challenge to deploy this product to work in Amazonia. The aim of this work is to disseminate the techniques used and help other enterprises with the same challenges. (author)

Designing a reliable leak bio-detection system for natural gas pipelines

Monitoring of natural gas (NG) pipelines is an important task for economical/safety operation, loss prevention and environmental protection. Timely and reliable leak detection of gas pipeline, therefore, plays a key role in the overall integrity management for the pipeline system. Owing to the various limitations of the currently available techniques and the surveillance area that needs to be covered, the research on new detector systems is still thriving. Biosensors are worldwide considered as a niche technology in the environmental market, since they afford the desired detector capabilities at low cost, provided they have been properly designed/developed and rationally placed/networked/maintained by the aid of operational research techniques. This paper addresses NG leakage surveillance through a robust cooperative/synergistic scheme between biosensors and conventional detector systems; the network is validated in situ and optimized in order to provide reliable information at the required granularity level. The proposed scheme is substantiated through a knowledge based approach and relies on Fuzzy Multicriteria Analysis (FMCA), for selecting the best biosensor design that suits both, the target analyte and the operational micro-environment. This approach is illustrated in the design of leak surveying over a pipeline network in Greece.

Bioinformatics tools designed to identify lentiviral or retroviral vector insertion sites in the genome of host cells are used to address the safety and long-term efficacy of hematopoietic stem cell gene therapy applications and to study the clonal dynamics of hematopoietic reconstitution. The increasing number of gene therapy clinical trials combined with the increasing amount of Next Generation Sequencing data, aimed at identifying integration sites, require both highly accurate and efficient computational software able to correctly process "big data" in a reasonable computational time. Here we present VISPA2 (Vector Integration Site Parallel Analysis, version 2), the latest optimized computational pipeline for integration site identification and analysis with the following features: (1) the sequence analysis for the integration site processing is fully compliant with paired-end reads and includes a sequence quality filter before and after the alignment on the target genome; (2) an heuristic algorithm to reduce false positive integration sites at nucleotide level to reduce the impact of Polymerase Chain Reaction or trimming/alignment artifacts; (3) a classification and annotation module for integration sites; (4) a user friendly web interface as researcher front-end to perform integration site analyses without computational skills; (5) the time speedup of all steps through parallelization (Hadoop free). We tested VISPA2 performances using simulated and real datasets of lentiviral vector integration sites, previously obtained from patients enrolled in a hematopoietic stem cell gene therapy clinical trial and compared the results with other preexisting tools for integration site analysis. On the computational side, VISPA2 showed a > 6-fold speedup and improved precision and recall metrics (1 and 0.97 respectively) compared to previously developed computational pipelines. These performances indicate that VISPA2 is a fast, reliable and user-friendly tool for

Eye of the storm : Enbridge's Michigan leak and debate over the integrity of North America's sprawling network of aging pipelines

International Nuclear Information System (INIS)

Stastny, R.P.

2010-01-01

In the aftermath of Enbridge's oil spill in Michigan from a pipe break, the company may face greater scrutiny in its Northern Gateway application for a pipeline crossing British Columbia to the coast, where tankers would ship Alberta bitumen to Asia. In addition, regulators in the United States are more likely to be more diligent regarding TransCanada's Keystone pipeline expansion and extension to the U.S. Gulf Coast, where refineries wait to process Canadian bitumen. The Enbridge spill has sparked a debate over the integrity of North America's aging pipelines. Operators claim that transmission pipelines can operate for an indefinite period of time, provided that the appropriate maintenance and inspection practices are used. Repairs can include outright replacement of corroded pipe sections or less demanding in-situ repairs to damaged pipe coatings or cathode replacement. Coatings and cathodic protection protects pipelines from the external environment. Pigging and chemicals prevent internal corrosion from water, carbon dioxide, hydrogen sulphide, chlorines and other residues. Despite these maintenance and repair efforts, many of the pipes currently in the ground were engineered for a useful life of 20 or 25 years. 6 figs.

High-throughput screening generates large volumes of heterogeneous data that require a diverse set of computational tools for management, processing, and analysis. Building integrated, scalable, and robust computational workflows for such applications is challenging but highly valuable. Scientific data integration and pipelining facilitate standardized data processing, collaboration, and reuse of best practices. We describe how Jenkins-CI, an “off-the-shelf,” open-source, continuous integration system, is used to build pipelines for processing images and associated data from high-content screening (HCS). Jenkins-CI provides numerous plugins for standard compute tasks, and its design allows the quick integration of external scientific applications. Using Jenkins-CI, we integrated CellProfiler, an open-source image-processing platform, with various HCS utilities and a high-performance Linux cluster. The platform is web-accessible, facilitates access and sharing of high-performance compute resources, and automates previously cumbersome data and image-processing tasks. Imaging pipelines developed using the desktop CellProfiler client can be managed and shared through a centralized Jenkins-CI repository. Pipelines and managed data are annotated to facilitate collaboration and reuse. Limitations with Jenkins-CI (primarily around the user interface) were addressed through the selection of helper plugins from the Jenkins-CI community. PMID:27899692

Weir-Jones, I.; Sun, M. [Weir-Jones Engineering Consultants Ltd. (Canada)

2011-07-01

In the oil industry, monitoring pipeline structural integrity is necessary for both regulatory and environmental purposes. Weir-Jones Engineering Consultants developed an automated structural integrity monitoring (SIM) system, data on strain, displacement and temperature are continuously acquired and automatically transmitted to the monitoring personnel. The aim of this paper is to present this technology and its implementation on one of Inter Pipeline Fund's lines as well. The automated SIM equipment was installed on a new 42'' line at the crossing of the Clearwater River close to Fort McMurray. Results showed that this technology is a good way to monitor pipelines in remote locations, environmentally sensitive areas, river and embankment crossings and in locations where external forces can put the pipeline at risk; but it should not be used otherwise as that would not be cost effective. This paper described the developed automated SIM and showed that it should only be used in specific locations to be cost effective.

2012-01-01

Pipeline integrity assessments are performed using conventional deterministic approaches, even though there are many uncertainties about the parameters in the pipeline integrity assessment. In this paper, a probabilistic assessment method is provided for the gas pipeline with corrosion defects based on the current corroded pipe evaluation criteria, and the failure probability of corroded pipelines due to the uncertainties of loadings, material property and measurement accuracy is estimated using Monte-Carlo technique. Furthermore, the sensitivity analysis approach is introduced to rank the influence of various random variables to the safety of pipeline. And the method to determine the critical defect size based on acceptable failure probability is proposed. Highlights: ► The folias factor in pipeline corrosion assessment methods was analyzed. ► The probabilistic method was applied in corrosion assessment methods. ► The influence of assessment variables to the reliability of pipeline was ranked. ► The acceptable failure probability was used to determine the critical defect size.

Attempting to pipeline integrity proceeding of PETROBRAS, the OSBRA (Sao Paulo-Brasilia Pipeline) Management promoted field inspections by divers at Paranaiba River water crossing, located at your right-of-way pipeline. These services were composed by topography, visual inspections and local screened of the pipeline, determining the equipment layout at that water crossing. At Paranaiba River, the pipeline is seated above the river bed. The results indicated high spans in the pipeline structure. Considering this configuration, were made water speed and vibration measurements near the equipment. The activities were executed in order to assist the structural analysis of the pipeline. These studies had concluded to a temporary solution, which consisted in reducing loads and building additional supports. (author)

Monitoring of natural gas (NG) pipelines is an important task for economical/safety operation, loss prevention and environmental protection. Timely and reliable leak detection of gas pipeline, therefore, plays a key role in the overall integrity management for the pipeline system. Owing to the various limitations of the currently available techniques and the surveillance area that needs to be covered, the research on new detector systems is still thriving. Biosensors are worldwide considered as a niche technology in the environmental market, since they afford the desired detector capabilities at low cost, provided they have been properly designed/developed and rationally placed/networked/maintained by the aid of operational research techniques. This paper addresses NG leakage surveillance through a robust cooperative/synergistic scheme between biosensors and conventional detector systems; the network is validated in situ and optimized in order to provide reliable information at the required granularity level. The proposed scheme is substantiated through a knowledge based approach and relies on Fuzzy Multicriteria Analysis (FMCA), for selecting the best biosensor design that suits both, the target analyte and the operational micro-environment. This approach is illustrated in the design of leak surveying over a pipeline network in Greece. Copyright © 2010 Elsevier B.V. All rights reserved.

1996-01-01

On May 26, 1994, the Defense Nuclear Facilities Safety Board (DNFSB) issued Recommendation 94-1. The concern is that the halt in production of materials to be used in nuclear weapons froze the manufacturing pipeline in a state that, for safety reasons, should not be allowed to persist unremediated. This recommendation had eight specific sub-recommendations that dealt with the potential problems. Specifically, the Board expressed concern about certain liquids and solids containing fissile materials and other radioactive substances located in spent fuel storage pools, reactor basins, reprocessing canyons; and various other facilities once used for processing and weapons manufacture. The WSRC and DOE-SR acknowledges and shares the Board's concerns and has developed this Integrated Stabilization Management Plan (ISMP) to aggressively address these urgent problems in a systems engineering approach

Real-Time Location-Based Rendering of Urban Underground Pipelines

2018-01-01

Full Text Available The concealment and complex spatial relationships of urban underground pipelines present challenges in managing them. Recently, augmented reality (AR has been a hot topic around the world, because it can enhance our perception of reality by overlaying information about the environment and its objects onto the real world. Using AR, underground pipelines can be displayed accurately, intuitively, and in real time. We analyzed the characteristics of AR and their application in underground pipeline management. We mainly focused on the AR pipeline rendering procedure based on the BeiDou Navigation Satellite System (BDS and simultaneous localization and mapping (SLAM technology. First, in aiming to improve the spatial accuracy of pipeline rendering, we used differential corrections received from the Ground-Based Augmentation System to compute the precise coordinates of users in real time, which helped us accurately retrieve and draw pipelines near the users, and by scene recognition the accuracy can be further improved. Second, in terms of pipeline rendering, we used Visual-Inertial Odometry (VIO to track the rendered objects and made some improvements to visual effects, which can provide steady dynamic tracking of pipelines even in relatively markerless environments and outdoors. Finally, we used the occlusion method based on real-time 3D reconstruction to realistically express the immersion effect of underground pipelines. We compared our methods to the existing methods and concluded that the method proposed in this research improves the spatial accuracy of pipeline rendering and the portability of the equipment. Moreover, the updating of our rendering procedure corresponded with the moving of the user’s location, thus we achieved a dynamic rendering of pipelines in the real environment.

An integrated pipeline to create and experience compelling scenarios in virtual reality

Springer, Jan P.; Neumann, Carsten; Reiners, Dirk; Cruz-Neira, Carolina

2011-03-01

One of the main barriers to create and use compelling scenarios in virtual reality is the complexity and time-consuming efforts for modeling, element integration, and the software development to properly display and interact with the content in the available systems. Still today, most virtual reality applications are tedious to create and they are hard-wired to the specific display and interaction system available to the developers when creating the application. Furthermore, it is not possible to alter the content or the dynamics of the content once the application has been created. We present our research on designing a software pipeline that enables the creation of compelling scenarios with a fair degree of visual and interaction complexity in a semi-automated way. Specifically, we are targeting drivable urban scenarios, ranging from large cities to sparsely populated rural areas that incorporate both static components (e. g., houses, trees) and dynamic components (e. g., people, vehicles) as well as events, such as explosions or ambient noise. Our pipeline has four basic components. First, an environment designer, where users sketch the overall layout of the scenario, and an automated method constructs the 3D environment from the information in the sketch. Second, a scenario editor used for authoring the complete scenario, incorporate the dynamic elements and events, fine tune the automatically generated environment, define the execution conditions of the scenario, and set up any data gathering that may be necessary during the execution of the scenario. Third, a run-time environment for different virtual-reality systems provides users with the interactive experience as designed with the designer and the editor. And fourth, a bi-directional monitoring system that allows for capturing and modification of information from the virtual environment. One of the interesting capabilities of our pipeline is that scenarios can be built and modified on-the-fly as they are

The Common Pipeline Library (CPL) is a set of ISO-C libraries that provide a comprehensive, efficient and robust software toolkit to create automated astronomical data reduction pipelines. Though initially developed as a standardized way to build VLT instrument pipelines, the CPL may be more generally applied to any similar application. The code also provides a variety of general purpose image- and signal-processing functions, making it an excellent framework for the creation of more generic data handling packages. The CPL handles low-level data types (images, tables, matrices, strings, property lists, etc.) and medium-level data access methods (a simple data abstraction layer for FITS files). It also provides table organization and manipulation, keyword/value handling and management, and support for dynamic loading of recipe modules using programs such as EsoRex (ascl:1504.003).

Genome Modeling System: A Knowledge Management Platform for Genomics.

Full Text Available In this work, we present the Genome Modeling System (GMS, an analysis information management system capable of executing automated genome analysis pipelines at a massive scale. The GMS framework provides detailed tracking of samples and data coupled with reliable and repeatable analysis pipelines. The GMS also serves as a platform for bioinformatics development, allowing a large team to collaborate on data analysis, or an individual researcher to leverage the work of others effectively within its data management system. Rather than separating ad-hoc analysis from rigorous, reproducible pipelines, the GMS promotes systematic integration between the two. As a demonstration of the GMS, we performed an integrated analysis of whole genome, exome and transcriptome sequencing data from a breast cancer cell line (HCC1395 and matched lymphoblastoid line (HCC1395BL. These data are available for users to test the software, complete tutorials and develop novel GMS pipeline configurations. The GMS is available at https://github.com/genome/gms.

Continuing data assessment of 16-inch williams pipeline inspected with the recently developed ultrasonic crack detection tool

International Nuclear Information System (INIS)

Katz, D.C.; Gao, M.; Elboujdaini, M.; Li, J.

2003-01-01

The in-line-Inspection of Williams' Gas West Pipeline in September 2001 was successfully completed using the newly developed 16-inch UltraScan CD tool of GE PII Pipeline Solutions. The particular pipeline section inspected was known to be affected by Stress Corrosion Cracking (SCC). The inspection was carried out using the liquid batching technique developed by PII Pipeline Solutions. A special launcher and receiver barrel was designed to enable the handling of a series of three batching pigs in front of and two behind the inspection tool. A manifold of 'kicker lines' was mounted to the barrel to launch the batching pigs and the inspection tool. The main benefits of this new design were minimizing operational downtime, ensuring complete air/natural gas displacement from the launcher, and providing for a smoother launch procedure. Due to the large elevation changes within the pipeline section, a key concern was maintaining pig velocity within 1m/s for adequate data resolution. Rather than rely on a general 'rule of thumb', a transient analysis was performed to define a range of possible batch sizes and better understand the expected pressure gradients while pumping the water slug. Based on actual data collected during this successful run, the transient model will be refined to better handle friction effects between the sealing cups and disks in future batch inspection runs. The pig data was successfully acquired, processed, verified, and excavations performed in 2002. Results from the twenty digs will be presented, as well as a discussion of the on-going fracture mechanics assessments which are being used to develop an overall integrity management plan for the continued, safe operation of the pipeline. To better understand the mechanism for SCC and enhance the integrity management plan, key metallurgical and environment elements are being investigated with advanced analytical tools, including high resolution SEM and EDS.

Permanent cathodic protection monitoring systems for offshore pipelines

Energy Technology Data Exchange (ETDEWEB)

Britton, Jim [Deepwater Corrosion Services Inc., Houston, TX (United States)

2009-07-01

Historically offshore pipeline cathodic protection monitoring has relied on the use of portable survey techniques. This has typically relied on ROV assisted or surface deployed survey methods. These methods have been shown to have technical as well as economic shortcomings, this is particularly true of buried offshore pipelines where accuracy is always questionable. As more focus is being placed on offshore pipeline integrity, it was time for a new method to emerge. The technology discussed involves the retro-placement of permanent clamp-on monitors onto the pipeline which can measure pipeline to seawater potential as well as current density. The sensors can be interrogated locally using light powered subsea voltage readouts. Application of the technology can be either during pipeline construction, during installation of life extension CP systems, or during routine subsea pipeline interventions. The new method eliminates the need for long cables or expensive acoustic or modulated data transfer and provides all the information required to fully verify CP system performance, thus eliminating the need for expensive close-interval surveys. Some deployment case histories will be presented along with feasibility of application on deep water pipelines and comparative economics. (author)

In order to improve the requirements of industrial processes, many decision support systems have been introduced in recent years. In this context, the alarm management systems have great relevance. On the other hand, the informatics revolution allowed a great increase of information concerning the operation of the industrial processes. Currently, process operators handle an excessive number of about 1.500 alarms per day. Thus, this overdose of information implies in the discredit of alarms. Then, in order to improve the operation activities of industrial processes, it is mandatory to incorporate procedures to evaluate and rationalize alarms. Since the EMMUA191 Standard is the reference guide to alarm management, but it does not specify how to execute an alarm management procedure, in this paper, a systematic procedure to evaluate alarms configurations in industrial processes is proposed. This procedure is in line with EMMUA191 and is composed by the following steps: to use statistics analyses to identify problematic alarms, such as occurrence, intermittency, correlation, and flooding calculation; to indicate problematic alarm group; and to propose a set of actions to be implemented. To validate our proposal, we present a case study in a gas pipeline plant using the BR-AlarmExpert software. (author)

Qualitative and quantitative analysis of small non-coding RNAs by next generation sequencing (smallRNA-Seq) represents a novel technology increasingly used to investigate with high sensitivity and specificity RNA population comprising microRNAs and other regulatory small transcripts. Analysis of smallRNA-Seq data to gather biologically relevant information, i.e. detection and differential expression analysis of known and novel non-coding RNAs, target prediction, etc., requires implementation of multiple statistical and bioinformatics tools from different sources, each focusing on a specific step of the analysis pipeline. As a consequence, the analytical workflow is slowed down by the need for continuous interventions by the operator, a critical factor when large numbers of datasets need to be analyzed at once. We designed a novel modular pipeline (iMir) for comprehensive analysis of smallRNA-Seq data, comprising specific tools for adapter trimming, quality filtering, differential expression analysis, biological target prediction and other useful options by integrating multiple open source modules and resources in an automated workflow. As statistics is crucial in deep-sequencing data analysis, we devised and integrated in iMir tools based on different statistical approaches to allow the operator to analyze data rigorously. The pipeline created here proved to be efficient and time-saving than currently available methods and, in addition, flexible enough to allow the user to select the preferred combination of analytical steps. We present here the results obtained by applying this pipeline to analyze simultaneously 6 smallRNA-Seq datasets from either exponentially growing or growth-arrested human breast cancer MCF-7 cells, that led to the rapid and accurate identification, quantitation and differential expression analysis of ~450 miRNAs, including several novel miRNAs and isomiRs, as well as identification of the putative mRNA targets of differentially expressed mi

The damage caused by Third Party Interference (TPI) is one of the major causes of pipeline failures. Consequently, new technologies for identifying activities that may cause damage to our pipelines are constantly being developed. A recently completed project sponsored by a number of pipeline operators has investigated the use of high-resolution satellites for the integrity management of onshore transmission pipelines. The sponsors were BG Technology (on behalf of Transco), Dansk Olie NatureGas, Gasunie, BP, Gaz de France, Distrigas, and the Health and Safety Executive. The project started with a general review of the satellite technologies available and their potential. The study was then focussed on the identification of activities that might result in damage to the pipeline and the potential of high-resolution optical satellites in identifying hazardous activities. A key element of the study was a comparison with existing surveillance systems, which generally involve regular aerial patrols of the pipeline route. To achieve this a survey was carried out to try and evaluate the costs and benefits of existing systems. In addition a simple model for analysing the cost benefit of pipeline surveillance was constructed, and a functional specification for a surveillance system drafted. Finally the performance of the IKONOS 2 high-resolution satellite system was tested in a controlled experiment using targets placed along a pipeline route. The results of this test were compared with a similar test of helicopter-based surveillance carried out by one of the sponsors. (author)

REMOTE DETECTION OF INTERNAL PIPELINE CORROSION USING FLUIDIZED SENSORS

Energy Technology Data Exchange (ETDEWEB)

Narasi Sridhar; Garth Tormoen; Ashok Sabata

2005-10-31

Pipelines present a unique challenge to monitoring because of the great geographical distances they cover, their burial depth, their age, and the need to keep the product flowing without much interruption. Most other engineering structures that require monitoring do not pose such combined challenges. In this regard, a pipeline system can be considered analogous to the blood vessels in the human body. The human body has an extensive ''pipeline'' through which blood and other fluids are transported. The brain can generally sense damage to the system at any location and alert the body to provide temporary repair, unless the damage is severe. This is accomplished through a vast network of fixed and floating sensors combined with a vast and extremely complex communication/decision making system. The project described in this report mimics the distributed sensor system of our body, albeit in a much more rudimentary fashion. Internal corrosion is an important factor in pipeline integrity management. At present, the methods to assess internal corrosion in pipelines all have certain limitations. In-line inspection tools are costly and cannot be used in all pipelines. Because there is a significant time interval between inspections, any impact due to upsets in pipeline operations can be missed. Internal Corrosion Direct Assessment (ICDA) is a procedure that can be used to identify locations of possible internal corrosion. However, the uncertainties in the procedure require excavation and location of damage using more detailed inspection tools. Non-intrusive monitoring techniques can be used to monitor internal corrosion, but these tools also require pipeline excavation and are limited in the spatial extent of corrosion they can examine. Therefore, a floating sensor system that can deposit at locations of water accumulation and communicate the corrosion information to an external location is needed. To accomplish this, the project is divided into four main

Plant genomes vary in size and are highly complex with a high amount of repeats, genome duplication and tandem duplication. Gene encodes a wealth of information useful in studying organism and it is critical to have high quality and stable gene annotation. Thanks to advancement of sequencing technology, many plant species genomes have been sequenced and transcriptomes are also sequenced. To use these vastly large amounts of sequence data to make gene annotation or re-annotation in a timely fashion, an automatic pipeline is needed. JGI plant genomics gene annotation pipeline, called integrated gene call (IGC), is our effort toward this aim with aid of a RNA-seq transcriptome assembly pipeline. It utilizes several gene predictors based on homolog peptides and transcript ORFs. See Methods for detail. Here we present genome annotation of JGI flagship green plants produced by this pipeline plus Arabidopsis and rice except for chlamy which is done by a third party. The genome annotations of these species and others are used in our gene family build pipeline and accessible via JGI Phytozome portal whose URL and front page snapshot are shown below.

Virtual Instrumentation Corrosion Controller for Natural Gas Pipelines

Science.gov (United States)

Gopalakrishnan, J.; Agnihotri, G.; Deshpande, D. M.

2012-12-01

Corrosion is an electrochemical process. Corrosion in natural gas (methane) pipelines leads to leakages. Corrosion occurs when anode and cathode are connected through electrolyte. Rate of corrosion in metallic pipeline can be controlled by impressing current to it and thereby making it to act as cathode of corrosion cell. Technologically advanced and energy efficient corrosion controller is required to protect natural gas pipelines. Proposed virtual instrumentation (VI) based corrosion controller precisely controls the external corrosion in underground metallic pipelines, enhances its life and ensures safety. Designing and development of proportional-integral-differential (PID) corrosion controller using VI (LabVIEW) is carried out. When the designed controller is deployed at field, it maintains the pipe to soil potential (PSP) within safe operating limit and not entering into over/under protection zone. Horizontal deployment of this technique can be done to protect all metallic structure, oil pipelines, which need corrosion protection.

PETROBRAS in search of being a benchmark in safety, environment and health, established in July 2001 a work group to elaborate a standard for Pipeline Integrity Management. This standard set the requirements for Pipeline Integrity Management and establishes, among others criteria, the actions required to detect, monitor and control internal corrosion of pipelines. The first step to evaluate, monitor and control the internal corrosion is to define the corrosive potential of transported fluids. Some oil pipelines located in central and southern areas of the Campos Basin transport high water cut produced fluids (> 30%) and with demulsifiers, which allow oil and water separation and increase internal corrosion risks. Despite of these, it is not possible to check the internal corrosion rates using conventional techniques because the fluids are produced through sub-sea 'manifolds'. In order to investigate the possibility of corrosion inhibition by crude oils, laboratory tests were performed simulating real field conditions in terms of fluid compositions, water cut and temperature. Experiments were conducted to determine the corrosion rate of specimens, the emulsion stability and the initial temperature of wax precipitation. This paper presents the results of the study realized to define the fluids' corrosive potential of four Campos Basin platforms that are transported through sub-sea 'manifolds. (author)

According to the existing prognoses more than 1 million km of gas pipelines, oil pipelines and water pipelines are built up to the year 2030. The predominant portion is from gas pipelines. The safe continued utilization of the aging pipelines is a large challenge. In addition, the diagnostic technology, the evaluation and risk assessment have to be developed further. With the design of new oil pipelines and gas pipelines, aspects of environmental protection, the energy efficiency of transport and thus the emission reduction of carbon dioxide, the public acceptance and the market strategy of the exporters gain in importance. With the offshore pipelines one soon will exceed the present border of 2,000 m depth of water and penetrate into larger sea depths.

Planning international transit oil pipeline projects in Croatia

International Nuclear Information System (INIS)

Sekulic, G.; Vrbic, D.

2004-01-01

Planning and development of international oil pipeline projects are aimed primarily at enhancing the safety of crude oil supply. Pipeline development is affected by a variety of overlapping factors, such as energy - and environment-protection-related factors, as well as political, economic, legislative, social, technical and technological ones. The success of any pipeline planning, construction and operation in the present conditions will depend upon the degree to which the above factors have been brought in line with global trends. The government should create stable political, economic and legislative frameworks that will meet the global requirements of crude oil transport development. As regards (new) transportation companies, their function is to secure safe transport by providing competitive tariffs and granting environmental protection. A prerequisite for the pipeline planning is to have both major crude oil consumers and producers (as well as their economic and political integrations) consider any state or company as potential partners for crude oil transport and transit, respectively. Croatia and the JANAF transport company have been 'chosen' as one of priority routes for European supply with crude oil from the Caspian region and Russia and one of the directions for Russian crude oil export due to a number of advantages, opportunities and prospects for a successful development. Two international oil pipeline projects - the Druzba Adria Project and the Constanta-Pancevo-Omisalj-Trieste Project - are currently under consideration. The government commitment towards these projects has been documented by the Croatian Energy Development Strategy (April 2002) and by the Programme for its implementation (March 2004). JANAF has assumed the responsibility for carrying out the project preparation activities assigned to it by the Croatian Government and the pertinent ministries. Cooperation between JANAF and government institutions is an integral part of the procedure

The Kepler mission is designed to continuously monitor up to 170,000 stars at a 30 minute cadence for 3.5 years searching for Earth-size planets. The data are processed at the Science Operations Center (SOC) at NASA Ames Research Center. Because of the large volume of data and the memory and CPU-intensive nature of the analysis, significant computing hardware is required. We have developed generic pipeline framework software that is used to distribute and synchronize the processing across a cluster of CPUs and to manage the resulting products. The framework is written in Java and is therefore platform-independent, and scales from a single, standalone workstation (for development and research on small data sets) to a full cluster of homogeneous or heterogeneous hardware with minimal configuration changes. A plug-in architecture provides customized control of the unit of work without the need to modify the framework itself. Distributed transaction services provide for atomic storage of pipeline products for a unit of work across a relational database and the custom Kepler DB. Generic parameter management and data accountability services are provided to record the parameter values, software versions, and other meta-data used for each pipeline execution. A graphical console allows for the configuration, execution, and monitoring of pipelines. An alert and metrics subsystem is used to monitor the health and performance of the pipeline. The framework was developed for the Kepler project based on Kepler requirements, but the framework itself is generic and could be used for a variety of applications where these features are needed.

Kuprion, Rainer; Hornig, Maja [TIB Chemicals Ag, Mannheim (Germany)

2009-07-01

Protective coating systems are one of the major defence mechanisms against corrosion for transmission pipelines, pipes within a refinery or petrochemical processing facilities. More and more pipelines are being constructed for the supply and transmission of gas and oil, each year but, in addition many existing pipelines are approaching an age where inspection reveals the necessity to consider complete refurbishment. However, the number of rehabilitation projects each year is still relatively small. Therefore, in the coming years, a rising need and necessity can be expected, for the owners and operating companies to be faced with the option of either replacing the pipeline or refurbishing of the existing pipeline. If the pipeline is known to have external corrosion, then safe and economic operation should be assured. Rehabilitation should be done before it is too late in order to ensure its future integrity and operational life. Rehabilitation of pipelines has been both the economic solution and, more significantly, the ecological solution and in many of those cases the coatings selected for the external protection has been multi component liquids based on 100% solids polyurethanes.

Failure Assessment for the High-Strength Pipelines with Constant-Depth Circumferential Surface Cracks

Directory of Open Access Journals (Sweden)

X. Liu

2018-01-01

Full Text Available In the oil and gas transportation system over long distance, application of high-strength pipeline steels can efficiently reduce construction and operation cost by increasing operational pressure and reducing the pipe wall thickness. Failure assessment is an important issue in the design, construction, and maintenance of the pipelines. The small circumferential surface cracks with constant depth in the welded pipelines are of practical interest. This work provides an engineering estimation procedure based upon the GE/EPRI method to determine the J-integral for the thin-walled pipelines with small constant-depth circumferential surface cracks subject to tension and bending loads. The values of elastic influence functions for stress intensity factor and plastic influence functions for fully plastic J-integral estimation are derived in tabulated forms through a series of three-dimensional finite element calculations for different crack geometries and material properties. To check confidence of the J-estimation solution in practical application, J-integral values obtained from detailed finite element (FE analyses are compared with those estimated from the new influence functions. Excellent agreement of FE results with the proposed J-estimation solutions for both tension and bending loads indicates that the new solutions can be applied for accurate structural integrity assessment of high-strength pipelines with constant-depth circumferential surface cracks.

Sustainability of social-environmental programs along pipelines

The sustainability of Social and Environmental programs along pipelines, have shown to be a major challenge. Gas pipelines in Bolivia and Brazil operate in a diversity of environments and communities with different cultures, values and expectations. However, the pipeline network can also provide opportunities for contributing to regional development and working with local populations on topics of mutual interest. Many of these are quite strategic because they arise from topics of mutual interest for both the company and neighboring populations, and because they provide opportunities for achieving results of mutual benefit. These opportunities could include helping to make gas available to local communities, contributions to urban planning, hiring local services and other initiatives. Sustainable and integrated Social and Environmental programs are therefore key to a successful pipeline operation. These opportunities are often missed or under valued. Some successful examples are presented from Transredes S.A., Bolivia. (author)

Pipeline abandonment - a discussion paper on technical and environmental issues

International Nuclear Information System (INIS)

1996-11-01

The technical and environmental issues associated with pipeline abandonment were reviewed to provide a basis for the development of guidelines that companies could follow in order to abandon oil and gas pipelines in an environmentally safe and economic manner. Some of the topics discussed include land use management, ground subsidence, soil and groundwater contamination, erosion and the potential to create water conduits. A major issue still to be resolved, i.e., the legal and financial aspects of pipeline abandonment, was addressed. An industry-financed fund has been created to cover the cost of reclamation and abandonment of orphaned pipelines and certain associated pipeline facilities. 30 refs., 4 tabs., 3 figs

The use of semantic similarity measures for optimally integrating heterogeneous Gene Ontology data from large scale annotation pipelines

Directory of Open Access Journals (Sweden)

Gaston K Mazandu

2014-08-01

Full Text Available With the advancement of new high throughput sequencing technologies, there has been an increase in the number of genome sequencing projects worldwide, which has yielded complete genome sequences of human, animals and plants. Subsequently, several labs have focused on genome annotation, consisting of assigning functions to gene products, mostly using Gene Ontology (GO terms. As a consequence, there is an increased heterogeneity in annotations across genomes due to different approaches used by different pipelines to infer these annotations and also due to the nature of the GO structure itself. This makes a curator's task difficult, even if they adhere to the established guidelines for assessing these protein annotations. Here we develop a genome-scale approach for integrating GO annotations from different pipelines using semantic similarity measures. We used this approach to identify inconsistencies and similarities in functional annotations between orthologs of human and Drosophila melanogaster, to assess the quality of GO annotations derived from InterPro2GO mappings compared to manually annotated GO annotations for the Drosophila melanogaster proteome from a FlyBase dataset and human, and to filter GO annotation data for these proteomes. Results obtained indicate that an efficient integration of GO annotations eliminates redundancy up to 27.08 and 22.32% in the Drosophila melanogaster and human GO annotation datasets, respectively. Furthermore, we identified lack of and missing annotations for some orthologs, and annotation mismatches between InterPro2GO and manual pipelines in these two proteomes, thus requiring further curation. This simplifies and facilitates tasks of curators in assessing protein annotations, reduces redundancy and eliminates inconsistencies in large annotation datasets for ease of comparative functional genomics.

Outlook '98 - Gas and oil pipelines

International Nuclear Information System (INIS)

Curtis, B.

1998-01-01

Due to rising North American demand, especially by the United States, by the end of 1997 there were plans to build 15 new pipelines over the next three years, at an estimated cost of $17 billion. Canada''s proximity to the United States, combined with huge Canadian reserves, and the fact that Canada already supplies some 15 per cent of U.S. requirements, makes Canada the obvious choice for filling future demand. This explains why most, if not all, current pipeline expansion projects are targeting markets in the U.S. Market forces will determine which of the projects will actually go forward. From the point of view of the Canadian Energy Pipeline Association pipeline regulatory reform, pipeline safety, integrity and climate change will be the Association''s key concerns during 1998. To that end, the Association is cooperating with the National Energy Board in a multi-million dollar study of stress corrosion cracking. The Association has also developed a Manual of Recommended Practices for the use of member companies to assist them to tailor stress corrosion cracking practices to their own operations. Meeting Canada''s commitment at the Kyoto Conference for greenhouse gas emissions of six per cent below 1990 levels by the year 2008 to 2012 (in effect a 25 per cent reduction from the level anticipated in the year 2000), a very difficult task according to industry experts, is also among the high priority items on the pipeline industry''s agenda for 1998

Visual operations management (VOM) takes advantage of visual cues to communicate information, simplify processes and improve the quality and safety of operations. Because of heightened competition, the importance of standardization and quality management processes has become more evident for pipeline companies. Petrobras Transporte's marine terminal units has been working over the last years to be recognized as a reference in the activities it pursues. This is based on the Petrobras Transporte's strategic plan 2020, which foresees amongst others, the specialization of technical workforce, operational safety excellence, capital discipline, customer satisfaction, the search for new technologies and markets and the rendering of new services. To achieve these goals, the Marine Terminals standardization program must be adhered to. Focusing on communication and adoption of standards and procedures, this paper describes how visual guides were conceived and implemented within Petrobras Transporte to enable operators and technicians to meet operational, environmental and occupational health and safety requirements.

GE PII IMU Mapping inspection system measures pipeline location coordinates (x, y, z) and provides data for determining pipeline curvature and consequential pipeline bending strain. The changes in strain can be used in the application of structural analyses and integrity evaluation of pipeline systems. This paper reviews the Inertia Measuring Unit (IMU) system and field investigation works performed on a high-pressure gas pipeline for E.ON Ruhrgas AG. The Inertial Measuring Unit of the pipeline inspection tool provides continuous measurement of the pipeline centreline coordinates. More than one inspection run was performed which allowed a more accurate strain comparison to be made. Repeatability is important to establish the reasons for increasing strain values detected at specific pipeline sections through in-line inspection surveys conducted in regular intervals over many years. Moreover, the flexibility resulting from a combination of different sensor technologies, makes it possible to provide a more complete picture of the overall situation. This paper reviews the work involved in detecting, locating and determining the magnitude and type of strain corresponding to the pipeline movement in field. (author)

Nanninga, N; Slifka, A; Levy, Y; White, C

2010-01-01

Hydrogen pipeline systems offer an economical means of storing and transporting energy in the form of hydrogen gas. Pipelines can be used to transport hydrogen that has been generated at solar and wind farms to and from salt cavern storage locations. In addition, pipeline transportation systems will be essential before widespread hydrogen fuel cell vehicle technology becomes a reality. Since hydrogen pipeline use is expected to grow, the mechanical integrity of these pipelines will need to be validated under the presence of pressurized hydrogen. This paper focuses on a review of the fatigue crack growth response of pipeline steels when exposed to gaseous hydrogen environments. Because of defect-tolerant design principles in pipeline structures, it is essential that designers consider hydrogen-assisted fatigue crack growth behavior in these applications.

Crossing Active Faults on the Sakhalin II Onshore Pipeline Route: Pipeline Design and Risk Analysis

International Nuclear Information System (INIS)

Mattiozzi, Pierpaolo; Strom, Alexander

2008-01-01

Twin oil (20 and 24 inch) and gas (20 and 48 inch) pipeline systems stretching 800 km are being constructed to connect offshore hydrocarbon deposits from the Sakhalin II concession in the North to an LNG plant and oil export terminal in the South of Sakhalin island. The onshore pipeline route follows a regional fault zone and crosses individual active faults at 19 locations. Sakhalin Energy, Design and Construction companies took significant care to ensure the integrity of the pipelines, should large seismic induced ground movements occur during the Operational life of the facilities. Complex investigations including the identification of the active faults, their precise location, their particular displacement values and assessment of the fault kinematics were carried out to provide input data for unique design solutions. Lateral and reverse offset displacements of 5.5 and 4.5 m respectively were determined as the single-event values for the design level earthquake (DLE) - the 1000-year return period event. Within the constraints of a pipeline route largely fixed, the underground pipeline fault crossing design was developed to define the optimum routing which would minimize stresses and strain using linepipe materials which had been ordered prior to the completion of detailed design, and to specify requirements for pipe trenching shape, materials, drainage system, etc. Detailed Design was performed with due regard to actual topography and to avoid the possibility of the trenches freezing in winter, the implementation of specific drainage solutions and thermal protection measures

Development of leak-rupture criteria for axially through-wall cracked pipelines

Energy Technology Data Exchange (ETDEWEB)

Zhu, X.K.; Leis, B.N. [Battelle Memorial Inst., Columbus, OH (United States)

2009-07-01

In this study, J-integral based fracture mechanics were used to characterize the fracture behaviour of a pipeline from crack initiation and stable growth to tearing instability. The aim of the study was to develop an effective leak-rupture criterion for pipelines with axial through-wall cracks (TWC). The J driving force for cracked plates and pipes was estimated using a plastic influence function method. The EPRI estimation scheme and R6 method were used to obtain a general estimate of the J-integral of the pipe. The failure pressures of a TWC pipe at fracture initiation and instability were then modelled in order to define a leak-rupture boundary. Fracture initiation and instability analyses for the TWC pipeline were illustrated. Results of the study showed that the method can be used to improve the accuracy of J driving force estimation and the leak-rupture criterion for pipeline applications. 20 refs., 5 figs.

Nowadays specifications require strict Yield to Tensile ratio limitation, nevertheless a fully accepted engineering assessment of its influence on pipeline integrity is still lacking. Probabilistic analysis based on structural reliability approach (Limit State Design) aimed at quantifying the Y/T ratio influence on failure probabilities of offshore pipelines was made. In particular, Tenaris seamless pipe data were used as input for the probabilistic failure analysis. The LSD approach has been applied to two actual deep water design cases that have been on purpose selected, and the most relevant failure modes have been considered. Main result of the work is that the quantitative effect of the Y/T ratio on failure probabilities of a deep water pipeline resulted not so big as expected; it has a minor effect, especially when failure modes are governed by Y only.

The Rio de Janeiro is one of 27 units of Brazil. It is located in the eastern portion of the Southeast and occupies an area of 43 696.054 km², being effectively the 3rd smallest state in Brazil. This state in recent years has suffered from erosion problems caused by the deployment of the network pipeline. The deployment pipeline is part of the activities related to the oil industry has caused a more intense conflict between the environment and economic activities, modifying the soil structure and distribution of surface and subsurface flows. This study aimed to analyze the erosion caused by the removal of soil for the deployment of pipeline transportation, with the consequences of the emergence of numerous gullies, landslides and silting of rivers. For the development of this study were performed bibliographic research, field work, mapping and digital preparation of the initial diagnosis of active processes and what the consequent environmental impacts. For these reasons, we conclude that the problems could be avoided or mitigated if there was a prior geological risk management. (author)

Interferometry has become a proven technique for accurately measuring ground movements caused by subsidence, landslides, earthquakes and volcanoes. Using space borne sensors such as the ERS, ENVISAT and RADARSAT satellites, ground deformation can be monitored on a millimeter level. Traditionally interferometry has been limited to arid areas however new technology has allowed for successful monitoring in vegetated regions and areas of changing land-cover. Analysis of ground movement of the Trans-Alaskan pipeline demonstrates how these techniques can offer pipeline engineers a new tool for observing potential dangers to pipeline integrity. Results from Interferometric Point Target Analysis were compared with GPS measurements and speckle tracking interferometry was demonstrated to measure a major earthquake. (author)

Method of drying long-distance pipelines in sections

Energy Technology Data Exchange (ETDEWEB)

Steinhaus, H.; Meiners, D.

1989-04-11

This invention provides a method of drying long distance pipelines using a vacuum, and provides high-quality drying over the whole length of the pipeline in a manageable and easily followed process. Evacuation of the pipeline is effected by means of a vacuum pump located at least at one point of the section of pipeline. The section is subsequently scavenged or flooded with scavenging gas. After a predetermined reduced pressure is reached, and while the vacuum pump continues to draw off, a scavenging is effected from the end or ends remote from the evacuation point with a molar flow rate of the stream of scavenging gas that is equal to or less than the evacuation stream in throughput, at least initially. The scavenging is effected not from the evacuation point, but from a remote point, and is also effected with a feed speed or feed amount that is throttled at least initially. This ensures that no condensation occurs even in the inner walls of the pipeline.

Pipelines are efficient, highly reliable and safe means of transportation. However, despite intensive right of way surveillance by foot, car and out of the air, pipeline leaks and illegal tappings are a reality - sometimes with catastrophic results. These events show a gap in real-time monitoring caused by the highly distributed nature of pipelines. Parts of this gap now can be closed with distributed fiber optic sensing technology. Using various physical effects this technology is apt to detect temperature, strain, vibrations and sound with very good localization over spans up to 50 km with a single sensor cable. Various field tested applications like leakage detection, third party activity monitoring and intrusion detection or ground movement detection as well as integrity monitoring proof that distributed fiber optic sensing can enhance pipeline safety and security.

A variety of advanced technologies are available to enhance planning, designing, managing, operating and maintaining the components of the electric utility system. Aerial and satellite remote sensing represents one area of rapid development that can be leveraged to address some of these challenges. Airborne remote sensing can be an effective technology to assist pipeline risk management to assure safety in design, construction, operation, maintenance, and emergency response of pipeline facilities. Industrial and scientific advances in airborne and satellite remote sensing systems and data processing techniques are opening new technological opportunities for developing an increased capability of accomplishing the pipeline mapping and safety needs of the industry. These technologies have significant and unique potential for application to a number of cross cutting energy system security issues. This paper addresses some of the applications of these technologies to pipeline and power industry infrastructure, economics and relative effectiveness of these technologies and issues related to technology implementation and diffusion.

During the stage of implementation of the land pipes enterprise, one of the main environmental aspects to be considered was the creation of solid and liquid waste. To mitigate the possible impacts to the environment, the main adopted mitigate measure was the implementation of a Waste Management Plan - WMP. Thus, the management of waste from pipes construction has the challenge of a great variety of stages and phases for the implementation of pipes and the diversity of local situations related to the topographic and hydro-geologic conditions. Considering the peculiarity of the pipes activities, this article proposes the elaboration of a Basic Guide to be used as reference for the creation of WMP's for similar enterprises, using as foundation the data from the three Gas Pipelines: Cabiunas - Vitoria; Vitoria - Cacimbas and Cacimbas - Catu. After the analysis of the three mentioned enterprises, it was verified that the waste management generated on the building and assembling of the land pipes normally occurs in accord with previous planning, but there's no systematization for the waste to be better recycled and reutilized, thus mitigating their creation.

Yan, Zijian; Zhang, Shenwei; Zhou, Wenxing

2014-01-01

This paper develops the probabilistic characteristics of the model errors associated with five well-known burst capacity models/methodologies for pipelines containing longitudinally-oriented external surface cracks, namely the Battelle and CorLAS™ models as well as the failure assessment diagram (FAD) methodologies recommended in the BS 7910 (2005), API RP579 (2007) and R6 (Rev 4, Amendment 10). A total of 112 full-scale burst test data for cracked pipes subjected internal pressure only were collected from the literature. The model error for a given burst capacity model is evaluated based on the ratios of the test to predicted burst pressures for the collected data. Analysis results suggest that the CorLAS™ model is the most accurate model among the five models considered and the Battelle, BS 7910, API RP579 and R6 models are in general conservative; furthermore, the API RP579 and R6 models are markedly more accurate than the Battelle and BS 7910 models. The results will facilitate the development of reliability-based structural integrity management of pipelines. - Highlights: • Model errors for five burst capacity models for pipelines containing surface cracks are characterized. • Basic statistics of the model errors are obtained based on test-to-predicted ratios. • Results will facilitate reliability-based design and assessment of energy pipelines

Quantitative Risk Assessment (QRA) of pipelines requires two main components to be provided. These are models of the consequences that follow from some loss of containment incident, and models for the likelihood of such incidents occurring. This paper describes how PETROBRAS have used Structural Reliability Analysis for the second of these, to provide pipeline- and location-specific predictions of failure frequency for a number of pipeline assets. This paper presents an approach to estimating failure rates for liquid and gas pipelines, using Structural Reliability Analysis (SRA) to analyze the credible basic mechanisms of failure such as corrosion and mechanical damage. SRA is a probabilistic limit state method: for a given failure mechanism it quantifies the uncertainty in parameters to mathematical models of the load-resistance state of a structure and then evaluates the probability of load exceeding resistance. SRA can be used to benefit the pipeline risk management process by optimizing in-line inspection schedules, and as part of the design process for new construction in pipeline rights of way that already contain multiple lines. A case study is presented to show how the SRA approach has recently been used on PETROBRAS pipelines and the benefits obtained from it. (author)

AmeriFlux is a network of scientists who independently collect eddy covariance and related environmental observations at over 250 locations across the Americas. As part of the AmeriFlux Management Project, the AmeriFlux Data Team manages standardization, collection, quality assurance / quality control (QA/QC), and distribution of data submitted by network members. To generate data products that are timely, QA/QC'd, and repeatable, and have traceable provenance, we developed a semi-automated data processing pipeline. The new pipeline consists of semi-automated format and data QA/QC checks. Results are communicated via on-line reports as well as an issue-tracking system. Data processing time has been reduced from 2-3 days to a few hours of manual review time, resulting in faster data availability from the time of data submission. The pipeline is scalable to the network level and has the following key features. (1) On-line results of the format QA/QC checks are available immediately for data provider review. This enables data providers to correct and resubmit data quickly. (2) The format QA/QC assessment includes an automated attempt to fix minor format errors. Data submissions that are formatted in the new AmeriFlux FP-In standard can be queued for the data QA/QC assessment, often with minimal delay. (3) Automated data QA/QC checks identify and communicate potentially erroneous data via online, graphical quick views that highlight observations with unexpected values, incorrect units, time drifts, invalid multivariate correlations, and/or radiation shadows. (4) Progress through the pipeline is integrated with an issue-tracking system that facilitates communications between data providers and the data processing team in an organized and searchable fashion. Through development of these and other features of the pipeline, we present solutions to challenges that include optimizing automated with manual processing, bridging legacy data management infrastructure with

An integrated multi−period planning of the production and transportation of multiple petroleum products in a single pipeline system

Directory of Open Access Journals (Sweden)

Alberto Herrán

2011-01-01

Full Text Available A multiproduct pipeline provides an economic way to transport large volumes of refined petroleum products over long distances. In such a pipeline, different products are pumped back−to−back without any separation device between them. The sequence and lengths of such pumping runs must be carefully selected in order to meet market demands while minimizing pipeline operational costs and satisfying several constraints. The production planning and scheduling of the products at the refinery must also be synchronized with the transportation in order to avoid the usage of the system at some peak−hour time intervals. In this paper, we propose a multi−period mixed integer nonlinear programming (MINLP model for an optimal planning and scheduling of the production and transportation of multiple petroleum products from a refinery plant connected to several depots through a single pipeline system. The objective of this work is to generalize the mixed integer linear programming (MILP formulation proposed by Cafaro and Cerdá (2004, Computers and Chemical Engineering where only a single planning period was considered and the production planning and scheduling was not part of the decision process. Numerical examples show how the use of a single period model for a given time period may lead to infeasible solutions when it is used for the upcoming periods. These examples also show how integrating production planning with the transportation and the use of a multi−period model may result in a cost saving compared to using a single−period model for each period, independently.

Corrosion Prevention And Control In High Pressure Oil And Gas Transmission Pipelines

International Nuclear Information System (INIS)

Hafez, M.T.; Radwan, M.H.; Jones, D.G.

2004-01-01

At the start of the 1990s there were concerns over the increasing threat of corrosion to the integrity of high-pressure oil and gas transmission pipelines. For example: corrosion was the major cause of reportable incidents in North America (1]. Corrosion was the major cause of pipeline failure in the Gulf of Mexico [2]. Corrosion in a North American onshore oil pipeline had required over $1 billion in repairs(3]. Internal corrosion along the complete length of pipelines had resulted in replacement[4] . However, the worldwide published failure statistics indicate that the incidents of corrosion are not increasing year on year(5-9]. Indeed, CONCA WE[8,9] statistics (for pipelines In Western Europe) show that the failure rate from corrosion (the most likely failure mode with increasing age) has not increased with pipeline age (Figure 1). In fact the statistics for gas pipelines in Europe

Constructing natural gas pipelines in wide areas requires investments of a huge amount. Many countries are building natural gas supply infrastructures under public support as nations' basic policy of promoting use of natural gas. This paper describes the present conditions of building pipelines in Western Europe, the U.S.A., Korea and Taiwan. In Western Europe, transporting companies established in line with the national policy own trunk pipelines and storage facilities, and import and distribute natural gas. The U.S.A. has 2300 small and large pipeline companies bearing transportation business. Pipelines extend about 1.9 million kilometers in total, with trunk pipelines accounting for about 440,000 kilometers. The companies are given eminent domain for the right of way. Korea has a plan to build a pipeline network with a distance of 1600 kilometers in around 2000. Taiwan has completed trunk pipelines extending 330 kilometers in two years. In Japan, the industry is preparing draft plans for wide area pipeline construction. 5 figs., 1 tab.

In this paper we present GAIA's findings in three corporate social responsibility projects along pipelines owned by three Brazilian companies in gas, oil and mining sectors. The projects had as the main goal to improve the relationship with communities in the companies' direct influence areas. Clearly, the relationship with communities along pipelines is essential to prevent and reduce industrial hazards. The damage in pipelines due to agriculture, buildings, intentional perforations and traffic of heavy vehicles may cause fatal accidents, environmental and material losses. Such accidents have negative consequences with regard to economy, image and relationship with communities and environmental agencies. From communities' perspective, pipelines deteriorate their life quality due to risk of industrial hazards nearby their houses. The lack of proper information about the pipelines remarkably increases insecurity feelings and discourses against the companies among community leaders. The methodology developed by GAIA comprises companies' and communities' interests and encompasses nine stages. 1. Socio-environmental appraisal or inventory, mapping main risks, communities' needs and their leaders. 2. Communication plan, defining strategies, languages and communication vehicles for each stakeholder group. 3. Inter-institutional meetings to include other institutions in the program. 4. Launching seminar in partnership with local authorities, divulging companies' actions in the cities with pipelines. 5. Multiplier agents formation, enabling teachers, local leaders and government representatives to disseminate correct information about the pipelines such as their functioning, hazard prevention, maintenance actions, and restrictions of activities over the pipelines. 6. Formation on project management, enabling teachers, local leaders and government representatives to elaborate, fund raise and manage socio environmental projects aimed at

This paper describes the potential economic impact and benefits to Alberta from the proposed development of the Alaska Highway Pipeline (AHP) and the Mackenzie Valley Pipeline (MVP). It also includes a planning framework for business and industry in the province. Each proposed pipeline was evaluated separately. The paper includes a list of Alberta companies that stand to benefit from the construction of one or both pipelines. The main findings indicate that northern pipeline development will bring opportunities to Alberta business in design, construction and management. There will be a secondary impact on petrochemical industries and infrastructure. Both pipeline developments will increase employment and yield billions of dollars in gross domestic product. The existing oil and gas industry in Alberta will receive value-added opportunities in areas of specialized expertise such as natural gas and natural gas liquid storage, natural gas liquid processing, and gas to liquid technology projects. The industry will also benefit from power generation and cogeneration. The northern pipelines have the potential to improve the role of First Nations in economic development. Gas consumers in Alberta should benefit from a secure supply of gas and lower prices. refs., tabs., figs

Given the lack of a complete and comprehensive library of microbial reference genomes, determining the functional profile of diverse microbial communities is challenging. The available functional analysis pipelines lack several key features: (i) an integrated alignment tool, (ii) operon-level analysis, and (iii) the ability to process large datasets. Here we introduce our open-sourced, stand-alone functional analysis pipeline for analyzing whole metagenomic and metatranscriptomic sequencing data, FMAP (Functional Mapping and Analysis Pipeline). FMAP performs alignment, gene family abundance calculations, and statistical analysis (three levels of analyses are provided: differentially-abundant genes, operons and pathways). The resulting output can be easily visualized with heatmaps and functional pathway diagrams. FMAP functional predictions are consistent with currently available functional analysis pipelines. FMAP is a comprehensive tool for providing functional analysis of metagenomic/metatranscriptomic sequencing data. With the added features of integrated alignment, operon-level analysis, and the ability to process large datasets, FMAP will be a valuable addition to the currently available functional analysis toolbox. We believe that this software will be of great value to the wider biology and bioinformatics communities.

The study of stress-strain relationship is very important in many designs of buried structures over the years. The behavior and mechanism between the interaction of soil and buried structures such as a natural pipeline will mostly contributes to the integrity of the pipeline. This paper presents a fully coupled finite element of consolidation analysis model to study the stress-strain distribution along a buried pipeline before it excess its maximum deformation limit. The behavior of the soil-pipeline system can be modelled by a non-linear elasto-plastic based on Mohr-Coulomb and critical state yield surfaces. The deformation and deflection of the pipeline due to drained and external loading condition will be considered here. Finally the stress-strain distribution of the buried pipeline will be utilised to obtain the maximum deformation limit and the deflection of the buried pipeline. (Author)

Faced with another year of high unemployment and shrinking markets, Western Canada's unionized pipeline construction trades have taken a step toward stabilizing the industry. The unions have struck a bargain to combat an increasing number of non-union open shops. Management and labor cooperated to insure that the unions regain their share of the pipeline construction market. The pipeline construction boom has ended, with an overcapacity, a downturn in sales, and few major projects on the drawing boards. The bargains included wage reductions of 30%, daily living allowance reductions of nearly 50%, the elimination of double time, and the use of composite crews.

The Alumbrera copper-gold mine located in the Province of Catamarca, northwest region of Argentina, commenced operation in October, 1997. Mine development included a 316 km long, 175 mm diameter slurry pipeline that conveys copper concentrate to a dewatering facility near the city of Tucuman, Province of Tucuman. It became apparent during the first few years of operation that, given the many potential risks of pipeline exposure associated with stream crossings, Minera Alumbrera would have to undertake an aggressive, formal program of risk management of crossings and risk mitigation. In this paper, the experience associated with two crossings is addressed: Rio Villavil; and, Rio Gastona. The original pipeline route through the 10 km length of pipeline connecting Pump Station (PS) 2 to PS 3 was directed along the bottom of the Rio Villavil valley, with most of it located within the flood way of the stream. The exposure of the pipeline at some locations and high risk of further pipeline exposures led to initiation of risk mitigation planning. Remediation work was completed by 2008. Rio Gastona, during the summer of 2001, experienced rapid shifting of the left bank at the crossing resulting in an undermined and unsupported length of pipeline. The subsequent risk mitigation method adopted in 2001 involved the planning and construction of groyne fields along both banks. (author)

Pipelines have the highest capacity and are the safest and the least environmentally disruptive way for gas or oil transmission. Recently, failures due to corrosion defects have become of major concern in maintaining pipeline integrity. A number of solutions have been developed for the assessment of remaining strength of corroded pipelines. However, these solutions are known to be dependent on material properties and pipeline geometries. In this paper, a fitness-for-purpose type limit load solution for corroded gas pipelines made of the X65 steel is proposed. For this purpose, a series of burst tests with various types of corrosion defects are performed. Finite element simulations are carried out to derive an appropriate failure criterion. And then, further, extensive finite element analyses are performed to obtain the FFP type limit load solution for corroded X65 gas pipelines as a function of defect depth, length and pipeline geometry. And also, a window based computer program for the assessment of corrosion defect, which is named as COPAP(COrroded Pipeline Assessment Program) has been developed on the basis of proposed limit load solution

This paper presents the development of an integrated simulation model, for the numerical calculation of thermal-hydraulic behaviors in the Brazilian southeast onshore gas pipeline flow system, remotely operated by TRANSPETRO's Gas Pipeline Control Centre (CCG). In its final application, this model is supposed to provide simulated results at the closer range to reality, in order to improve gas pipeline simulation studies and evaluations for the system in question. Considering the fact that numerical thermo-hydraulic simulation becomes the CCG's most important tool to analyze the boundary conditions to adjust the mentioned gas flow system, this paper seeks and takes aim to the optimization of the following prime attributions of a gas pipeline control centre: verification of system behaviors, face to some unit maintenance stop or procedure, programmed or not, or to some new gas outlet or inlet connection to the system; daily operational compatibility analysis between programmed and realized gas volumes; gas technical expedition and delivery analysis. Finally, all this work was idealized and carried out within the one-phase flow domain (dry gas) (author)

Reasons for decision in the matter of Maritimes and Northeast Pipeline Management Ltd

2000-01-01

Maritimes and Northeast Pipeline Management Ltd. (M and NP) applied to the National Energy Board (NEB) for final tolls effective 1 December 1999 for the lateral natural gas pipeline from their mainline to Point Tupper, Nova Scotia. The application covered a ten-month test period. The initial application included the costs and volumes associated with the mainline and the Point Tupper lateral pipeline but was subsequently amended to remove the Point Tupper Lateral costs and volumes because it was doubtful that the lateral would be in service during the test period. The mainline went into service on 1 December 1999 and gas first flowed to market on 31 December 1999. This report presented the revenue requirements authorized by the NEB for the test period and summarized the applied-for rate base and the approved rate base for the test period. It also provided a detailed account of mainline construction costs, including project cost estimates, master construction agreement, governance and compensation structure, and incentive compensation plans. The applicant, M and NP, believes that the NEB should make its judgement according to the applied-for costs and not on the accuracy of the previous cost estimates. This report also presented the opposing views of the intervenors regarding just and reasonable tolls. The intervenors included the Canadian Association of Petroleum Producers, the East Coast Producer Group, Shell, the province of New Brunswick, the Nova Scotia Petroleum Directorate and the NEB. The Board has made several decisions, many in favor of M and NP regarding rate base, debt financing costs, rate of return on rate base, operating and maintenance costs, deferral accounts, deferral of toll hearing costs, disposition of account balances and carrying charges, and tariff matters. The final 8 orders of the NEB were listed in Appendix 1 of this report as Order TG-5-2000. 3 tabs., 3 appendices

Halifax Lateral Pipeline Project : comprehensive study report

International Nuclear Information System (INIS)

1998-12-01

The National Energy Board has requested the preparation of a comprehensive study report (CSR) for the proposed Halifax Lateral Pipeline Project in support of Maritimes and Northeast Pipeline Company's proposal to construct the lateral pipeline to transport natural gas produced in offshore Nova Scotia to the Tufts Cove electric generating station in the Halifax Regional Municipality. The project will also enhance the access of natural gas to potential markets located along the pipeline route. This CSR was prepared according to guidelines of the Canadian Environmental Assessment Agency. The report presents: (1) an overview of the project, (2) a summary of the regulatory requirements for assessment, (3) a description of the environmental assessment and regulatory process to date, (4) a summary of the predicted residual environmental and socio-economic effects associated with the project, and (5) a summary of the public consultation process. The environmental and socio-economic assessment focused on these eleven issues: groundwater resources, surface water resources, wetlands, soils, air quality, fish habitat, rare herpetiles, mammals, avifauna, rare plants and archaeological heritage resources. The report identified potential interactions between the project and valued socio-economic and environmental components. These were addressed in combination with recommended mitigative measures to reduce potential adverse effects. It was concluded that the overall environmental effects from the proposed project are likely to be minimal and can be effectively managed with good environmental management methods. 14 refs., 5 tabs., 5 figs., 2 appendices

During the stage of implementation of the land pipes enterprise, one of the main environmental aspects to be considered was the creation of solid and liquid waste. To mitigate the possible impacts to the environment, the main adopted mitigate measure was the implementation of a Waste Management Plan - WMP. Thus, the management of waste from pipes construction has the challenge of a great variety of stages and phases for the implementation of pipes and the diversity of local situations related to the topographic and hydro-geologic conditions. Considering the peculiarity of the pipes activities, this article proposes the elaboration of a Basic Guide to be used as reference for the creation of WMP's for similar enterprises, using as foundation the data from the three Gas Pipelines: Cabiunas - Vitoria; Vitoria - Cacimbas and Cacimbas - Catu. After the analysis of the three mentioned enterprises, it was verified that the waste management generated on the building and assembling of the land pipes normally occurs in accord with previous planning, but there's no systematization for the waste to be better recycled and reutilized, thus mitigating their creation.

The Niigata-Sendai natural gas pipeline was constructed in 1996 by Japan Petroleum Exploration Co. to transmit indigenous gas produced off Niigata Pref. and imported gas from Indonesia in the form of LNG to Tohoku Electric Power Co.`s Sendai Thermal Power Station. It is the second longest onshore pipeline in Japan extending 251km (nominal diameter: 20in.). Kawasaki Steel participated in the construction project from the preliminary investigation and planning stage, and constructed a 97km long section, which is approximately 39% of the total length. Various new techniques were applied to secure safety and reduce cost. This paper outlines the project and some of the representative techniques adopted for the project, such as field bends cold-worked on 11m long straight pipes, work management system for constructing long-distance pipelines, coordination for the test runs and verification of the designs. 3 refs., 12 figs., 5 tabs.

Hazardous waste management in pipeline terminal: a multi-pronged approach for safe disposal of tank bottom sludge

Energy Technology Data Exchange (ETDEWEB)

Ammanna, John [Indian Oil Corporation Limited (IOCL), Mumbai (India)

2009-12-19

Indian Oil Corporation Ltd., Pipeline Division owns and operates the 1850 Km long Salaya-Mathura Crude Oil Pipeline (SMPL) with installed capacity of 21 MMTPA. Almost 25 types of crude [90% imported and 10% indigenous] are received into 13 on-shore tanks at Vadinar (the Mother Station of SMPL) through 2 Nos. SPM's anchored in the Arabian Sea and located on the west coast of India in the Gulf of Kutch. Larger quantities of tank bottom sludge that gets generated in the terminal during tank M and I pose serious environmental hazards, as procedures for handling, treatment and disposal of hazardous waste are not well established. With increasingly stringent Environmental norms being enforced by Statutory / Regulatory Authorities, storage of hazardous solid waste in lagoons and its disposal through designated approved agencies within the specified time frame, becomes extremely difficult. This paper seeks to address this issue by putting forth an innovative approach to hazardous waste management in pipeline terminals having large crude oil tank farms that has been adopted at Indian Oil Corporation's Vadinar terminal of SMPL where a multi-pronged approach for safe disposal of tank bottom sludge has been successfully implemented. The terminal has since become a 'Zero sludge location'. (author)

A Novel Method to Enhance Pipeline Trajectory Determination Using Pipeline Junctions.

2016-04-21

Pipeline inspection gauges (pigs) have been used for many years to perform various maintenance operations in oil and gas pipelines. Different pipeline parameters can be inspected during the pig journey. Although pigs use many sensors to detect the required pipeline parameters, matching these data with the corresponding pipeline location is considered a very important parameter. High-end, tactical-grade inertial measurement units (IMUs) are used in pigging applications to locate the detected problems of pipeline using other sensors, and to reconstruct the trajectories of the pig. These IMUs are accurate; however, their high cost and large sizes limit their use in small diameter pipelines (8″ or less). This paper describes a new methodology for the use of MEMS-based IMUs using an extended Kalman filter (EKF) and the pipeline junctions to increase the position parameters' accuracy and to reduce the total RMS errors even during the unavailability of above ground markers (AGMs). The results of this new proposed method using a micro-electro-mechanical systems (MEMS)-based IMU revealed that the position RMS errors were reduced by approximately 85% compared to the standard EKF solution. Therefore, this approach will enable the mapping of small diameter pipelines, which was not possible before.

Pollution from pipelines

International Nuclear Information System (INIS)

1991-01-01

During the 1980s, over 3,900 spills from land-based pipelines released nearly 20 million gallons of oil into U.S. waters-almost twice as much as was released by the March 1989 Exxon Valdez oil spill. Although the Department of Transportation is responsible for preventing water pollution from petroleum pipelines, GAO found that it has not established a program to prevent such pollution. DOT has instead delegated this responsibility to the Coast Guard, which has a program to stop water pollution from ships, but not from pipelines. This paper reports that, in the absence of any federal program to prevent water pollution from pipelines, both the Coast Guard and the Environmental Protection Agency have taken steps to plan for and respond to oil spills, including those from pipelines, as required by the Clean Water Act. The Coast Guard cannot, however, adequately plan for or ensure a timely response to pipeline spills because it generally is unaware of specific locations and operators of pipelines

Supply chain management is an integrative philosophy about managing the flow of distribution channels from supplier to the consumer. PARCO, an oil and gas company in Pakistan has three existing pipelines. Out of three, two pipelines are running parallel from Karachi to Mehmood kot. One pipeline is of crude oil and meeting the demand of PARCO refinery while second pipeline is of High Speed Diesel (HSD) and third pipeline is of (HSD and Kerosene) running from Mehmood Kot to Machhike (Sheikhupura). PARCO supply petroleum products from Shikarpur, Mehmood Kot, Faisalabad and Machhike to oil marketing companies (OMCs) as per their share, standard and demand. The purpose of these pipelines is to meet the country demand for petroleum products at various locations all over Pakistan. In the peak season when OMCs have high demand and receipt of product from PARCO pipelines are less, there is a need to enhance the flow rate of oil inside the PARCO pipelines to fulfill the demand of OMCs. This could be done economically by the application of drag reduction theory. So by injecting drag reducer, dragging of the oil inside the pipeline could appreciably be reduced thereby improving the pumping of oil. (author)

Pipelines 'R' us

The geopolitical background to the export of oil and gas from Kazakhstan by pipeline is explored with particular reference to the sensitivities of the USA. There are now a number of pipeline proposals which would enable Kazakhstan to get its hydrocarbons to world markets. The construction of two of these formed part of a major oil deal signed recently with China in the face of stiff competition from major US companies. The most convenient and cost effective route, connecting up with Iran's existing pipeline network to the Gulf, is unlikely to be developed given continuing US sanctions against Iran. Equally unlikely seems to be the Turkmenistan to Pakistan pipeline in the light of the political volatility of Afghanistan. US companies continue to face limits on export capacity via the existing Russian pipelines from Kazakhstan. A temporary solution could be to carry some oil in the existing pipeline from Azerbaijan to Georgia which has been upgraded and is due to become operational soon, and later in a second proposed pipeline on this route. The Caspian Pipeline Consortium, consisting of three countries and eleven international companies, is building a 1500 km pipeline from the Tergiz field to Novorossiysk on the Black Sea with a view to completion in 2000. An undersea pipeline crossing the Caspian from Azerbaijan is being promoted by Turkey. There is an international perception that within the next five years Kazakhstan could be in a position to export its oil via as many as half a dozen different routes. (UK)

A Java-based fMRI processing pipeline evaluation system for assessment of univariate general linear model and multivariate canonical variate analysis-based pipelines.

As functional magnetic resonance imaging (fMRI) becomes widely used, the demands for evaluation of fMRI processing pipelines and validation of fMRI analysis results is increasing rapidly. The current NPAIRS package, an IDL-based fMRI processing pipeline evaluation framework, lacks system interoperability and the ability to evaluate general linear model (GLM)-based pipelines using prediction metrics. Thus, it can not fully evaluate fMRI analytical software modules such as FSL.FEAT and NPAIRS.GLM. In order to overcome these limitations, a Java-based fMRI processing pipeline evaluation system was developed. It integrated YALE (a machine learning environment) into Fiswidgets (a fMRI software environment) to obtain system interoperability and applied an algorithm to measure GLM prediction accuracy. The results demonstrated that the system can evaluate fMRI processing pipelines with univariate GLM and multivariate canonical variates analysis (CVA)-based models on real fMRI data based on prediction accuracy (classification accuracy) and statistical parametric image (SPI) reproducibility. In addition, a preliminary study was performed where four fMRI processing pipelines with GLM and CVA modules such as FSL.FEAT and NPAIRS.CVA were evaluated with the system. The results indicated that (1) the system can compare different fMRI processing pipelines with heterogeneous models (NPAIRS.GLM, NPAIRS.CVA and FSL.FEAT) and rank their performance by automatic performance scoring, and (2) the rank of pipeline performance is highly dependent on the preprocessing operations. These results suggest that the system will be of value for the comparison, validation, standardization and optimization of functional neuroimaging software packages and fMRI processing pipelines.

An analysis of the operation of the gas transportation system shows that for a considerable part of time pipelines operate in an unsettled regime of gas movement. Its pressure and flow rate vary along the length of pipeline and over time as a result of uneven consumption and selection, switching on and off compressor units, shutting off stop valves, emergence of emergency leaks. The operational management of such regimes is associated with difficulty of reconciling the operating modes of individual sections of gas pipeline with each other, as well as with compressor stations. Determining the grounds that cause change in the operating mode of the pipeline system and revealing patterns of these changes determine the choice of its parameters. Therefore, knowledge of the laws of changing the main technological parameters of gas pumping through pipelines in conditions of non-stationary motion is of great importance for practice.

Pipeline abandonment: a discussion paper on technical and environmental issues

1996-01-01

Formation of government/industry joint steering committee to oversee a review of pipeline abandonment and preparation of a discussion paper was reported. The review became urgent in view of the fact that many of the pipeline systems are nearing the end of their useful life, and the current absence of guidelines in Canada to deal with pipeline abandonment, or to offer guidance on ways of assessing abandonment costs and funding. In view of this situation the safety and the environmental, financial, and legal implications of abandoned pipelines have become an increasing concern to regulatory authorities and the oil and gas industry. Issues to be dealt with in the discussion paper include subsidence, contamination, water crossing, erosion, land management, restoration, utility and pipeline crossings, creation of water conduits, the cost of abandonment, operator choice of abandonment options, and the level of surface disturbance associated with such options

The Hanford Site includes 149 single-shell tanks, organized in 12 'tank farms,' with contents managed as high-level mixed waste. The Hanford Federal Facility Agreement and Consent Order requires that one tank farm, the Waste Management Area C, be closed by June 30, 2019. A challenge to this project is the disposition and closure of Waste Management Area C underground pipelines. Waste Management Area C contains nearly seven miles of pipelines and 200 separate pipe segments. The pipelines were taken out of service decades ago and contain unknown volumes and concentrations of tank waste residuals from past operations. To understand the scope of activities that may be required for these pipelines, an evaluation was performed. The purpose of the evaluation was to identify what, if any, characterization methods and/or closure actions may be implemented at Waste Management Area C for closure of Waste Management Area C by 2019. Physical and analytical data do not exist for Waste Management Area C pipeline waste residuals. To develop estimates of residual volumes and inventories of contamination, an extensive search of available information on pipelines was conducted. The search included evaluating historical operation and occurrence records, physical attributes, schematics and drawings, and contaminant inventories associated with the process history of plutonium separations facilities and waste separations and stabilization operations. Scoping analyses of impacts to human health and the environment using three separate methodologies were then developed based on the waste residual estimates. All analyses resulted in preliminary assessments, indicating that pipeline waste residuals presented a comparably low long-term impact to groundwater with respect to soil, tank and other ancillary equipment residuals, but exceeded Washington State cleanup requirement values. In addition to performing the impact analyses, the assessment evaluated available sampling technologies

Complex computational pipelines are becoming a staple of modern scientific research. Often these pipelines are resource intensive and require days of computing time. In such cases, it makes sense to run them over high performance computing (HPC) clusters where they can take advantage of the aggregated resources of many powerful computers. In addition to this, researchers often want to integrate their workflows into their own web servers. In these cases, software is needed to manage the submission of jobs from the web interface to the cluster and then return the results once the job has finished executing. We have developed the Job Management System (JMS), a workflow management system and web interface for high performance computing (HPC). JMS provides users with a user-friendly web interface for creating complex workflows with multiple stages. It integrates this workflow functionality with the resource manager, a tool that is used to control and manage batch jobs on HPC clusters. As such, JMS combines workflow management functionality with cluster administration functionality. In addition, JMS provides developer tools including a code editor and the ability to version tools and scripts. JMS can be used by researchers from any field to build and run complex computational pipelines and provides functionality to include these pipelines in external interfaces. JMS is currently being used to house a number of bioinformatics pipelines at the Research Unit in Bioinformatics (RUBi) at Rhodes University.

All questions and concerns of pipeline technique are dealt with in detail. Some chapters can be applied for petroleum pipelines only or partly, for example the importance of petroleum pipelines, projecting, calculation, and operation. The sections of pipes and formings, laying, rights of way, and corrosion protection, accessories and remote effect technique, however, are of general interest, for example also for gas pipelines. In the chapter on working material, a very good summary of today's pipe working material including the thermomechanically treated steels is given. Besides methods of improving the toughness, the problems of the corrosion caused by strain cracking and the ways of avoiding it are pointed out. The pipe producing methods and, in the end of the chapter, the tests in the factory are explained. The section of laying deals with the laying methods being applied for years in pipeline construction, a big part referring to welding methods and tests. Active and passive corrosion protection are explained with all details. In addition to the solidity calculation presented with special regard to concerns of petroleum pipelines, theoretical fundaments and calculation methods for pressure are dealt with. Beside general questions of pumps, accessories, and drives, there is a section dealing with measurement and control techniques. Furthermore, remote effect and transmission techniques and news systems are explained in detail. Here, problems are referred to which are applicable not only to the operation of mineral oil pipelines. The book is completed by indications as to pipeline operation emphasizing general operation control, maintenance, repair methods and damage and their elimination. The last chapter contains a collection of the legal fundaments and the technical rules.

Furthermore, the structural design of both a simple knowledge database and a real-time database are described. Finally, some short comments on the benefits and disadvantages of the proposed concept of data integration in RODOS are given. (orig.) [de

Gathering pipeline methane emissions in Fayetteville shale pipelines and scoping guidelines for future pipeline measurement campaigns

Daniel J. Zimmerle

2017-11-01

Full Text Available Gathering pipelines, which transport gas from well pads to downstream processing, are a sector of the natural gas supply chain for which little measured methane emissions data are available. This study performed leak detection and measurement on 96 km of gathering pipeline and the associated 56 pigging facilities and 39 block valves. The study found one underground leak accounting for 83% (4.0 kg CH4/hr of total measured emissions. Methane emissions for the 4684 km of gathering pipeline in the study area were estimated at 402 kg CH4/hr [95 to 1065 kg CH4/hr, 95% CI], or 1% [0.2% to 2.6%] of all methane emissions measured during a prior aircraft study of the same area. Emissions estimated by this study fall within the uncertainty range of emissions estimated using emission factors from EPA’s 2015 Greenhouse Inventory and study activity estimates. While EPA’s current inventory is based upon emission factors from distribution mains measured in the 1990s, this study indicates that using emission factors from more recent distribution studies could significantly underestimate emissions from gathering pipelines. To guide broader studies of pipeline emissions, we also estimate the fraction of the pipeline length within a basin that must be measured to constrain uncertainty of pipeline emissions estimates to within 1% of total basin emissions. The study provides both substantial insight into the mix of emission sources and guidance for future gathering pipeline studies, but since measurements were made in a single basin, the results are not sufficiently representative to provide methane emission factors at the regional or national level.

Risks derived from the handling of a combustible material transported under high pressure, by pipelines that pass close to where people live, makes it necessary to adopt prevention, mitigation and control measures to reduce the effect in case of ignition of a gas leak. This work shows the development of a new mathematical model to determine areas of high consequence and their application, using widely available and easy to use software, such as Google Earth and Excel, to determine and visualize the area up to which the level of radiation can affect the integrity of people and buildings. The model takes into account the pressure drop into the gas pipeline from the compression station, the gas leakage rate and possible forms of gas ignition. This development is an alternative to the use of specialized software and highly trained personnel. The simulation is applied to a traced of the Miraflores-Tunja gas pipeline, using a macro developed in Excel to determine the impact area and compare it with the coordinates of the vulnerable areas. The zones where these areas intersect are constituted in high consequence areas and are identified along with the sections of the pipeline that affect them, to provide the operator with a risk analysis tool for the determination and visualization of the gas pipeline and its environment.

Highlights: • Comprehensive analysis of the efficiency and safety strategies of transport CO 2 . • Selection of safety zones around pipelines transporting CO 2 . • Optimization of CO 2 pipeline transportation conditions. - Abstract: The aim of this paper is to analyze CO 2 compression and transportation processes with safety issues for post-combustion CO 2 capture applications for basic technological concepts of a 900 MW pulverized coal-fired power plant. Four various types of compressors including a conventional multistage centrifugal compressor, an integrally geared centrifugal compressor, a supersonic shock wave compressor, and pump machines were used. This study emphasizes that total compression power is a strong function of the thermodynamic process and is not only determined by the compressor efficiency. The compressor increases the CO 2 pressure from normal pressure to critical pressure and the boosting pump continues to increase the pressure to the required pressure for the pipeline inlet. Another problem analyzed in this study is the transport of CO 2 by pipeline from the compressor outlet site to the disposal site under heat transfer conditions. Simulations were made to determine maximum safe pipeline distance to subsequent booster stations depending on inlet pressure, environmental temperature, the thermal insulation thickness and the ground level heat transfer conditions. From the point of view of environmental protection, the most important problem is to identify the hazards which indirectly affect CO 2 transportation in a strict and reliable manner. This identification is essential for effective hazard management. A failure of pipelines is usually caused by corrosion, material defects, ground movement or third party interference. After the rupture of the pipeline transporting liquid CO 2 , a large pressure drop will occur. The pressure will continue to fall until the liquid becomes a mixture of saturated vapour/liquid.

The U.S. Geological Survey (USGS) recognizes and understands the importance of a diverse workforce in advancing our science. Valuing Differences is one of the guiding principles of the USGS, and is the critical basis of the collaboration among the Youth and Education in Science (YES) program in the USGS Office of Science, Quality, and Integrity (OSQI), the Office of Diversity and Equal Opportunity (ODEO), and USGS science centers to build pipeline programs targeting diverse young scientists. Pipeline programs are robust, sustained relationships between two entities that provide a pathway from one to the other, in this case, from minority serving institutions to the USGS. The USGS has benefited from pipeline programs for many years. Our longest running program, with University of Puerto Rico Mayaguez (UPR), is a targeted outreach and internship program that has been managed by USGS scientists in Florida since the mid-1980's Originally begun as the Minority Participation in the Earth Sciences (MPES ) Program, it has evolved over the years, and in its several forms has brought dozens of interns to the USGS. Based in part on that success, in 2006 USGS scientists in Woods Hole MA worked with their Florida counterparts to build a pipeline program with City College of New York (CCNY). In this program, USGS scientists visit CCNY monthly, giving a symposium and meeting with students and faculty. The talks are so successful that the college created a course around them. In 2017, the CCNY and UPR programs brought 12 students to the USGS for summer internships. The CCNY model has been so successful that USGS is exploring creating similar pipeline programs. The YES office is coordinating with ODEO and USGS science centers to identify partner universities and build relationships that will lead to robust partnership where USGS scientists will visit regularly to engage with faculty and students and recruit students for USGS internships. The ideal partner universities will have a

Full text : Considering all types of risks (technical, operational, natural hazards (e.g. geo-hazards) and third party intrusion), the underground pipelines constructed in accordance with the international standards are the most safe and reliable system for oil transportation. Statistical data provided by CONCAWE and US Department of Transportation confirms that the pipeline related spills are rare and mainly related to the old pipelines. Georgia's experience yet confirms the general sound guess that the situation in our countries is not the same as in western Europe or USA and accordingly the CONCAWE statistical data can not be applied mechanically. Two spills (although small and manageable), during the recent 4 years and some discovered illegal hot-taps on the Baku-Supsa pipeline indicate that the issue of third party intrusion risks is much higher in the region and well organized security system is required to protect the pipeline from intentional damage. Of course the pipeline system can not function isolated and it is integrated with the other systems of oil transportation, mainly with off-shore terminals and tankers. The most significant of the recorded pollution damages are related to the tanker collisions (like Prestige and Exxon Valdez cases). The basic fact, which we would like to stress, is that the environmental risks related to the tanker collisions are much higher for such confined or semi-confined systems as Black and Caspian seas. The overloading of the Black Sea transportation capacity and especially its limiting narrow point - the Bosporus will inevitably lead in future to the implementation of the restrictive measures limiting transportation of oil by tankers in the Black Sea. Therefore, the role of the BTC pipeline as major transportation system will increase significantly. We consider that responsibility of the scientific society is to facilitate this process as soon as the BTC pipeline is functional. The railway transportation of oil is quite

To solve the problems existing in the current Gas Company patrol management, such as inaccurate attendance, whether or not the patrol personnel exceed the scope of patrol inspection. This paper Proposed that we apply the SuperMap iDeskTop 8C plug-in desktop GIS application and development platform, the positioning function of GPS and the data transmission function of 3G/4G/GPRS/Ethernet to develop a gas pipeline inspection management system. We build association between real-time data, pipe network information, patrol data, map information, spatial data and so on to realize the bottom data fusion, use the mobile location system and patrol management client to achieve real-time interaction between the client and the mobile terminal. Practical application shows that the system has completed the standardized management of patrol tasks, the reasonable evaluation of patrol work and the maximum utilization of patrol resources.

This paper explored issues facing the complex task of managing pipelines that transport large volumes of petroleum products over long distances. Since oil pipelines are generally a few inches wide and several miles long, reasonable amounts of distinct products can be transported with very small loss due to the mixing at liquid boundaries. Optimizing the transportation through oil pipelines in terms of maintenance and environmental safety is a high priority for pipeline operators. This paper presented the Pipesworld model which takes into account features such as product interface constraints, limited product storage capacities and due dates for product delivery. It has been benchmarked as a start-of-art general purpose artificial planning system. This paper also reported the results derived by general purpose artificial intelligence planning systems when applied to the Pipesworld model. It demonstrated how various modelling techniques can be used to enhance the planners performance. Current work in developing Plumber was also presented. This dedicated solver that addresses operational situations uses both general purpose planning techniques as well as domain specific knowledge. When Plumber was incorporated into Pipesworld, its outperformed Fast-Forward, one of the best available general purpose planning systems, suggesting that improved versions of Plumber have the potential to deal with various problem scenarios in pipeline operations. 11 refs., 2 tabs., 3 figs.

Processing of next-generation sequencing (NGS) data requires significant technical skills, involving installation, configuration, and execution of bioinformatics data pipelines, in addition to specialized postanalysis visualization and data mining software. In order to address some of these challenges, developers have leveraged virtualization containers toward seamless deployment of preconfigured bioinformatics software and pipelines on any computational platform. We present an approach for abstracting the complex data operations of multistep, bioinformatics pipelines for NGS data analysis. As examples, we have deployed 2 pipelines for RNA sequencing and chromatin immunoprecipitation sequencing, preconfigured within Docker virtualization containers we call Bio-Docklets. Each Bio-Docklet exposes a single data input and output endpoint and from a user perspective, running the pipelines as simply as running a single bioinformatics tool. This is achieved using a "meta-script" that automatically starts the Bio-Docklets and controls the pipeline execution through the BioBlend software library and the Galaxy Application Programming Interface. The pipeline output is postprocessed by integration with the Visual Omics Explorer framework, providing interactive data visualizations that users can access through a web browser. Our goal is to enable easy access to NGS data analysis pipelines for nonbioinformatics experts on any computing environment, whether a laboratory workstation, university computer cluster, or a cloud service provider. Beyond end users, the Bio-Docklets also enables developers to programmatically deploy and run a large number of pipeline instances for concurrent analysis of multiple datasets. © The Authors 2017.

Full Text Available Scholars with different backgrounds have carried out extensive surveys centred on how 3D digital models, data acquisition and processing have changed over the years in fields of archaeology and architecture and more in general in the Cultural Heritage panorama: the current framework focused on reality-based modelling is then split in several branches: acquisition, communication and analysis of buildings (Pintus et alii, 2014. Despite the wide set of well-structured and all-encompassing surveys on the IT application in Cultural Heritage, several open issues still seem to be present, in particular once the purpose of digital simulacra is the one to fit with the “pre-informatics" legacy of architectural/archaeological representation (historical drawings with their graphic codes and aesthetics. Starting from a series of heterogeneous matters that came up studying two Italian UNESCO sites, this paper aims at underlining the importance of integrating different pipelines from different technological fields, in order to achieve multipurpose models, capable to comply with graphic codes of traditional survey, as well as semantic enrichment, and last but not least, data compression/portability and texture reliability under different lighting simulation.

Pipeline transmission systems have been designed traditionally using steady state simulations. Steady state simulation provided sufficient values for simple systems, but is limited in dealing with surges in flow rates, loss of facilities and facility operation. A dynamic approach is required to test the capacity of a system for various fluids. This paper investigated the use of transient analysis of liquid pipelines in order to improve the design of these pipelines and to achieve operational benefits. The transient method and its use are discussed. Dynamic analysis was applied to the Keystone Pipeline Project. The purpose of the study was first to determine the system capacity and data for transportation of Heavy DilBit, and then to implement batch transportation of a volume of synthetic crude oil. It was found that the use of transient modeling in design and operational assessment of a liquid pipeline ensures system capability, control, safety and integrity.

existing buried optical cable can be extended to encircle facilities such as well heads and Block Valve Stations and be monitored to provide perimeter protection and condition monitoring. Out in the field, activity close to a buried pipeline can be significant with farming activity, roads, urban encroachment and rivers all creating significant noise. We will show how, through the use of a system with a high acoustic sensitivity, small spatial resolution and sophisticated signal processing we are able to differentiate between normal activity and unusual activity that can be a threat to the pipeline. Examples of the detection of people, vehicles and excavators at significant ranges laterally offset from a buried cable will be shown. The paper will refer to data recorded on field deployed systems and discuss the further enhancements to the technology including extending the range beyond 120 km and integration of the alert information into existing SCADA systems. Finally, this paper we will briefly discuss the use of Distributed Acoustic Sensing to monitor subsea pipelines and how the technology may also be used to listen to completion and production activity downhole.

The traditional model of astronomers collecting their observations as raw instrument data is being increasingly replaced by astronomical observatories serving standard calibrated data products to observers and to the public at large once proprietary restrictions are lifted. For this model to be effective, observatories need the ability to periodically re-calibrate archival data products as improved master calibration products or pipeline improvements become available, and also to allow users to rapidly calibrate their data on-the-fly. Traditional astronomy pipelines are heavily I/O dependent and do not scale with increasing data volumes. In this paper, we present the One Degree Imager - Portal, Pipeline and Archive (ODI-PPA) calibration pipeline framework which integrates the efficient and parallelized QuickReduce pipeline to enable a large number of simultaneous, parallel data reduction jobs - initiated by operators AND/OR users - while also ensuring rapid processing times and full data provenance. Our integrated pipeline system allows re-processing of the entire ODI archive (˜15,000 raw science frames, ˜3.0 TB compressed) within ˜18 hours using twelve 32-core compute nodes on the Big Red II supercomputer. Our flexible, fast, easy to operate, and highly scalable framework improves access to ODI data, in particular when data rates double with an upgraded focal plane (scheduled for 2015), and also serve as a template for future data processing infrastructure across the astronomical community and beyond.

2006-01-01

The polyethylene(PE) pipes are widely used to transport city gas worldwide with steel pipes. Generally, Steel pipe are used for high pressure line and PE pipe for low pressure line whose pressure is less than 4 kg/m 2 . The steel pipe line are subject to 100 percent Radiographic Testing(RT) during installation stage, on the contrary, there has been no the established testing method for the welding fusion joint of polyethylene pipes, so all quality control is limited only Visual Testing(VT) or management of Fusion welding equipment. Even though PE pipeline is exposed to lower pressure than steel pipeline, the gas leakage from PE pipe may result in almost the same serious consequence from steel pipeline. So, it is necessary to develop the reliable testing standard for PE pipeline from the point of view of NDT engineers.

activities are involved in the flow of goods between place of origin and place of consumption or application:Demand forecasting, Facility site selection, Procurement,Materials handling, Packaging, Warehouse management, Inventory management,Order processing, Logistics communications, Transport, Reverse logistics. Because cost is incurred without adding value each time goods are handled (activity 4 at a terminal or storage facility, a primary logistics objective is to eliminate handling wherever possible. With the carriage of crude oil and petroleum products by pipeline this objective is fully met. Commodity intake, haulage, and discharge are combined in one process, usually a remote-controlled operation. Pipeline transport is a non-containerised bulk mode of transport thereby obviating the need for packaging (activity 5 and returning empty containers. Pipelines provide a direct and long-term link between these origins and destinations. If necessary a continuous service can be provided with no need for a return trip or a reverse pumping process (activity 11.The elimination of handling, packaging and reverse logistics activities contribute substantially to the high measure of economies of scale that pipeline transport enjoys. The article provides adscription of each of the eleven logistics activities in the context of pipeline transport. Effective logistics service is a prerequisite to help ensure that customers receive the required products at the desired quality and quantity, where and when needed. The most pertinent determinants of logistics service performance aresuitability, accessibility, goods security, transit time, reliability and flexibility. The article offers a discussion of the extent to which pipeline transport conforms to each of these measures of effectiveness.

Hao, M. J.; You, Q. J.; Yue, Z.

2017-11-01

Gas pipeline network is a major hazard source in urban areas. In the event of an accident, there could be grave consequences. In order to understand more clearly the causes and consequences of gas pipeline network accidents, and to develop prevention and mitigation measures, the author puts forward the application of improved bow-tie model to analyze risks of urban gas pipeline network. The improved bow-tie model analyzes accident causes from four aspects: human, materials, environment and management; it also analyzes the consequences from four aspects: casualty, property loss, environment and society. Then it quantifies the causes and consequences. Risk identification, risk analysis, risk assessment, risk control, and risk management will be clearly shown in the model figures. Then it can suggest prevention and mitigation measures accordingly to help reduce accident rate of gas pipeline network. The results show that the whole process of an accident can be visually investigated using the bow-tie model. It can also provide reasons for and predict consequences of an unfortunate event. It is of great significance in order to analyze leakage failure of gas pipeline network.

Schenk, Andreas D; Philippsen, Ansgar; Engel, Andreas; Walz, Thomas

2013-05-01

Electron crystallography of two-dimensional crystals allows the structural study of membrane proteins in their native environment, the lipid bilayer. Determining the structure of a membrane protein at near-atomic resolution by electron crystallography remains, however, a very labor-intense and time-consuming task. To simplify and accelerate the data processing aspect of electron crystallography, we implemented a pipeline for the processing of electron diffraction data using the Image Processing Library and Toolbox (IPLT), which provides a modular, flexible, integrated, and extendable cross-platform, open-source framework for image processing. The diffraction data processing pipeline is organized as several independent modules implemented in Python. The modules can be accessed either from a graphical user interface or through a command line interface, thus meeting the needs of both novice and expert users. The low-level image processing algorithms are implemented in C++ to achieve optimal processing performance, and their interface is exported to Python using a wrapper. For enhanced performance, the Python processing modules are complemented with a central data managing facility that provides a caching infrastructure. The validity of our data processing algorithms was verified by processing a set of aquaporin-0 diffraction patterns with the IPLT pipeline and comparing the resulting merged data set with that obtained by processing the same diffraction patterns with the classical set of MRC programs.

Overview of slurry pipelines

Energy Technology Data Exchange (ETDEWEB)

Gandhi, R L

1982-01-01

Slurry pipelines have proven to be a technically feasible, environmentally attractive and economic method of transporting finely divided particles over long distances. A pipeline system normally consists of preparation, pipeline and utilization facilities and requires optimization of all three components taken together. A considerable amount of research work has been done to develop hydraulic design of a slurry pipeline. Equipment selection and estimation of corrosion-erosion are considered to be as important as the hydraulic design. Future applications are expected to be for the large-scale transport of coal and for the exploitation of remotely located mineral deposits such as iron ore and copper. Application of slurry pipelines for the exploitation of remotely located mineral deposits is illustrated by the Kudremukh iron concentrate slurry pipeline in India.

Pipeline Drag Reducers

International Nuclear Information System (INIS)

Marawan, H.

2004-01-01

Pipeline drag reducers have proven to be an extremely powerful tool in fluid transportation. High molecular weight polymers are used to reduce the frictional pressure loss ratio in crude oil pipelines, refined fuel and aqueous pipelines. Chemical structure of the main used pipeline drag reducers is one of the following polymers and copolymers classified according to the type of fluid to ; low density polyethylene, copolymer of I-hexane cross linked with divinyl benzene, polyacrylamide, polyalkylene oxide polymers and their copolymers, fluorocarbons, polyalkyl methacrylates and terpolymer of styrene, alkyl acrylate and acrylic acid. Drag reduction is the increase in pump ability of a fluid caused by the addition of small amounts of an additive to the fluid. The effectiveness of a drag reducer is normally expressed in terms of percent drag reduction. Frictional pressure loss in a pipeline system is a waste of energy and it costly. The drag reducing additive minimizes the flow turbulence, increases throughput and reduces the energy costs. The Flow can be increased by more than 80 % with existing assets. The effectiveness of the injected drag reducer in Mostorod to Tanta crude oil pipeline achieved 35.4 % drag reduction and 23.2 % flow increase of the actual performance The experimental application of DRA on Arab Petroleum Pipeline Company (Summed) achieved a flow increase ranging from 9-32 %

In May, 2007, a series of tasks were implemented in the actives of the client at Patagonia, Argentina, with the purpose of applying a Pipeline Integrity System. The purpose of this system is to effectively operate their facilities in such a way that no adverse effects are suffered by their employees, the environment, or the public at large, which is one of the main goals followed by any oil pipeline operator. In this paper, all tasks, inspections, controls and records made by the operator about gas and liquid hydrocarbons Pipelines contemplated by local requirements, NAG 100 and Resolution 1460 are described. Firstly, a description of gas and liquid hydrocarbons transport systems was made. This description consisted in the recollection of basic information about construction, maintenance, operation and inspection. Later, tasks to complete the ILI process started by the company in the past were implemented. This implementation consisted in the analysis of inspections that were made, priority of anomalies to verify, definition of verifications, direct assessment and analysis of the results. A gap analysis was made with the purpose of stating the compliance level of the normative requirements for each system. This analysis consisted in the determination of the company's practices about applicable regulations. As a result of this, a series of duties were developed from the collection and integration of information, using the database that was already implemented by the company. A risk analysis was also made, based on the determination of the kind of events or adverse conditions that can make an impact in the oil pipeline, the possibilities that these events or condition can conduct to a failure, and the seriousness of the possible consequences that these failures can produce. With the results of the risk analysis, the Inspection plan developed by the company was refreshed and it resulted in an improvement Plan in data collection and identification of sensitive

This ammonia pipeline is about 30 km long and links the Fertilizer Plant (FAFEN-BA) to the Urea Marine Terminal (TMU) at the Port of Aratu in Candeias (Bahia State, Brazil). In this study, we characterize the remnants of vegetation and quantify the Permanent Preservation Areas. Furthermore, we propose areas and techniques for their recovery and / or management. The methodology was based on the Rapid Ecological Assessment, which combines selection of areas through remote sensing image analysis, with rapid field campaigns in the selected points. This methodology, successfully applied in PETROBRAS refineries, is first applied in a pipeline influence area. During these campaigns, the main aspects of vegetation, such as phyto physiognomy and ecological succession stages, were registered in field data sheets prepared for this purpose. The most representative remnants of vegetation that could be quantified were Atlantic Forest fragments, as well as those in the Permanent Preservation Areas. (author)

This paper presented newly developed steady-state and dynamic models commissioned for natural gas liquids (NGL) pipelines near Empress, Alberta. The work demonstrates a unique university-industry collaboration for solving the challenge of reliable pipeline leak detection. The flexible, custom real-time leak detection system was tested on the dynamic simulation. It was successfully used to replace a volume balance system for NGL pipelines at Empress in March 2003. A custom pipeline monitoring system was also developed to integrate with the existing pipeline supervisory control and data acquisition (SCADA) system. Simulation results enabled a change in the control scheme of the pipelines that resulted in less transient operation. The premise of the leak detection system is a rigorous thermodynamics and dynamic mass balance calculation based on real-time information from field flow, pressure and temperature sensors. The application of the system makes it possible to minimize or eliminate false or nuisance alarms, which is critical to the confidence of the monitoring system. The volumetric and mass imbalance formulae permit the system to cross check the calculation and then make important decisions regarding the sounding of alarms. The custom solution offers flexibility for use in a wide variety of conditions and applications. In addition, it is cost effective and locally supported. 8 refs., 4 tabs., 5 figs.

International Nuclear Information System (INIS)

Shelton, E.

1999-01-01

An overview of the new TransCanada energy transmission system was given. TransCanada has ownership interests in seven other North American natural gas pipelines and the integration of former NOVA Gas Transmission, TransCanada Energy Transmission and ANG Pipeline organizations into a single organization is nearing completion. Integration efforts have been driven by TransCanada's commitment to provide customers with lower costs and improved service levels. The service enhancements will include one-stop shopping, customer advisory councils, harmonized design criteria, optimized operations/maintenance, and consistent billing processes. The new toll design which will replace the current postage-stamp pricing regime offered by NGTL was also reviewed, emphasizing key features such as pricing, term linked tolls, interruptible/short term tolls, renewal incentive, risk/reward collar, transition period and new services

Fusion energy science, like other science areas in DOE, is becoming increasingly data intensive and network distributed. We discuss data management techniques that are essential for scientists making discoveries from their simulations and experiments, with special focus on the techniques and support that Fusion Simulation Project (FSP) scientists may need. However, the discussion applies to a broader audience since most of the fusion SciDAC's, and FSP proposals include a strong data management component. Simulations on ultra scale computing platforms imply an ability to efficiently integrate and network heterogeneous components (computational, storage, networks, codes, etc), and to move large amounts of data over large distances. We discuss the workflow categories needed to support such research as well as the automation and other aspects that can allow an FSP scientist to focus on the science and spend less time tending information technology

The recently issued International Atomic Energy Agency (IAEA) publications (GS-R-3, GS-G-3.1 and GS-G-3.5) regarding Management Systems for Facilities and Activities define requirements for creation, introduction, evaluation and continuously improvement of the Management System, which unifies the safety, health, environment, security, quality and economic elements. According to GS-R-3 the Integrated Management System is based on defined processes identified in the enterprises: Managing, Basic and Supporting processes. At implementation of their activities, the organizations often apply other standards in their interrelations with suppliers and the parties concerned - ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007, regarding quality, environment and occupational health and safety management. The integration of the standards of both series ensure the observance of the common management principles that reflect the best practices of management as leadership, participation of the people, process approach, continuously improvement, systematical approach to the management and approach based on facts used at the making decisions. The main objective of the Integrated Management System introduction is to ensure safety considering the influence of all additional impacts taken together. The Integrated Management System is based on the process approach at implementation of the activities in nuclear power plant. The transition to the process oriented approach require long period of time, during which the distribution of the responsibilities is optimized up to the level that will satisfy the requirements, reach and maintain the stipulated objectives. The Configuration Management (CM) is an integrated management process by means of which conformity between design requirements, physical configuration and the plant documentation is ascertained and maintained during the entire life cycle of the facility. Processes within configuration management are not isolated, but are part of

INTEGRATIVE AUGMENTATION OF STANDARDIZED MANAGEMENT SYSTEMS

Directory of Open Access Journals (Sweden)

Stanislav Karapetrovic

2008-03-01

Full Text Available The development, features and integrating abilities of different international standards related to management systems are discussed. A group of such standards that augment the performance of quality management systems in organizations is specifically focused on. The concept, characteristics and an illustrative example of one augmenting standard, namely ISO 10001, are addressed. Integration of standardized augmenting systems, both by themselves and within the overall management system, is examined. It is argued that, in research and practice alike, integrative augmentation represents the future of standardized quality and other management systems.

High-throughput sequencing of bisulfite-converted DNA is a technique used to measure DNA methylation levels. Although a considerable number of computational pipelines have been developed to analyze such data, none of them tackles all the peculiarities of the analysis together, revealing limitations that can force the user to manually perform additional steps needed for a complete processing of the data. This article presents bicycle, an integrated, flexible analysis pipeline for bisulfite sequencing data. Bicycle analyzes whole genome bisulfite sequencing data, targeted bisulfite sequencing data and hydroxymethylation data. To show how bicycle overtakes other available pipelines, we compared them on a defined number of features that are summarized in a table. We also tested bicycle with both simulated and real datasets, to show its level of performance, and compared it to different state-of-the-art methylation analysis pipelines. Bicycle is publicly available under GNU LGPL v3.0 license at http://www.sing-group.org/bicycle. Users can also download a customized Ubuntu LiveCD including bicycle and other bisulfite sequencing data pipelines compared here. In addition, a docker image with bicycle and its dependencies, which allows a straightforward use of bicycle in any platform (e.g. Linux, OS X or Windows), is also available. ograna@cnio.es or dgpena@uvigo.es.

The article describes the experience of the area of Social Responsibility in TRANSPETRO, a wholly Brazilian Subsidiary of PETROBRAS, which operates in the field of transport of petroleum, its by-products and gas, by way of oil and gas pipeline networks. Pipeline is the safety option for the transport of these products, but requires monitoring and the permanent management of the use and occupation of the soil and surrounding area. This care does not only depend on the Company as responsibility is much wider. Active participation by the communities affected by the operations is essential, principally in incorporating the rules of occupation and the use of the soil in the land surrounding the strips and the terminals. This participation is justified given that the action of third parties represents a significant proportion (70%) of the irregular situations registered by the Company. Community Relationship Management is one of the principal strategies to increase the safety of the pipelines integrated into the Company's programs of maintenance and operational control. Therefore, a plan of Community Relations has been implanted, focusing on the transformation of values to construct a community culture of co-habitation and co-responsibility for the pipeline land.

System-Enforced Deterministic Streaming for Efficient Pipeline Parallelism

Institute of Scientific and Technical Information of China (English)

张昱; 李兆鹏; 曹慧芳

2015-01-01

Pipeline parallelism is a popular parallel programming pattern for emerging applications. However, program-ming pipelines directly on conventional multithreaded shared memory is difficult and error-prone. We present DStream, a C library that provides high-level abstractions of deterministic threads and streams for simply representing pipeline stage work-ers and their communications. The deterministic stream is established atop our proposed single-producer/multi-consumer (SPMC) virtual memory, which integrates synchronization with the virtual memory model to enforce determinism on shared memory accesses. We investigate various strategies on how to efficiently implement DStream atop the SPMC memory, so that an infinite sequence of data items can be asynchronously published (fixed) and asynchronously consumed in order among adjacent stage workers. We have successfully transformed two representative pipeline applications – ferret and dedup using DStream, and conclude conversion rules. An empirical evaluation shows that the converted ferret performed on par with its Pthreads and TBB counterparts in term of running time, while the converted dedup is close to 2.56X, 7.05X faster than the Pthreads counterpart and 1.06X, 3.9X faster than the TBB counterpart on 16 and 32 CPUs, respectively.

Decontamination device for pipeline

International Nuclear Information System (INIS)

Harashina, Heihachi.

1994-01-01

Pipelines to be decontaminated are parts of pipelines contaminated with radioactive materials, and they are connected to a fluid transfer means (for example, a bladeless pump) and a ball collector by way of a connector. The fluid of a mixture of chemical decontaminating liquid and spheres is sent into pipelines to be decontaminated. The spheres are, for example, heat resistant porous hard or soft rubber spheres. The fluid discharged from the pipelines to be decontaminated are circulated by way of bypassing means. The inner surface of the pipelines is decontaminated by the circulation of the fluid. When the bypass means is closed, the fluid discharged from the pipelines to be decontaminated is sent to the ball collector, and the spheres are captured by a hopper. Further, the liquid is sent to the filtrating means to filter the chemical contaminating liquid, and sludges contained in the liquid are captured. (I.N.)

As Hydrogen's transmit and diffuse, after gestating for a while, the density of hydrogen around crack tip of pipeline will get to the critical density, and the pipeline material will descend, make critical stress factor, the reason of pipeline Hydrogen Induced Cracking is Hydrogen's transmit and diffuse. The stress factor of Hydrogen Induced Cracking under surroundings-condition of stress is the key that estimate material's rupture behavior. The paper study the relationship among hydrogen concentrate, crack tip stress, stain field, hydrogen diffusion and inner pressure for crack tip process zone, then determined the length of HIC (hydrogen induced cracking) process zone. Based on the theory of propagation which reason micro-crack making core, dislocation model is produced for fracture criteria of HIC, the influence between material and environments under the HIC is analyzed, step by step pipeline maximum load pressure and threshold of J-integrity ( J{sub ISCC} ) is calculated, which is very significant for pipeline safety operation.

It is impractical to transport bitumen and heavy oil by pipelines at ambient temperature unless diluents are added to reduce the viscosity. A diluted bitumen pipeline is commonly referred to as a dilbit pipeline. The diluent routinely used is natural gas condensate. Since natural gas condensate is limited in supply, it must be recovered and reused at high cost. This paper presented an alternative to the use of diluent to reduce the viscosity of heavy oil or bitumen. The following two basic design issues for a hot bitumen (hotbit) pipeline were presented: (1) modelling the restart problem, and, (2) establishing the maximum practical operating temperature. The transient behaviour during restart of a high temperature pipeline carrying viscous fluids was modelled using the concept of flow capacity. Although the design conditions were hypothetical, they could be encountered in the Athabasca oilsands. It was shown that environmental disturbances occur when the fluid is cooled during shut down because the ground temperature near the pipeline rises. This can change growing conditions, even near deeply buried insulated pipelines. Axial thermal loads also constrain the design and operation of a buried pipeline as higher operating temperatures are considered. As such, strain based design provides the opportunity to design for higher operating temperature than allowable stress based design methods. Expansion loops can partially relieve the thermal stress at a given temperature. As the design temperature increase, there is a point at which above grade pipelines become attractive options, although the materials and welding procedures must be suitable for low temperature service. 3 refs., 1 tab., 10 figs.

The aim of this paper is to show a new approach to solve integrated gas balance planning problems that defines the best compression and transmission strategy for a system with a large number of platforms or compression units that are interlinked with the delivery points through a complex gas pipeline network. For solving the proposed optimization problem is used a genetic meta-heuristic technique, where the fitness function of the algorithm is the Profit function of the gas balance, being considered the incomes and costs besides the pipeline network constraints, representing the compression system and transmission network near to the real operational condition. Newton Raphson's method is used to solve the nonlinear system that represents the calculation of the pressure drop in the gas pipeline network that can contain various cycles. This model could be used for design and optimization of gas pipeline networks, as well as for the gas balance planning of an existent network looking for the profit maximization. (author)

The Pipeline Pargo/Garoupa 22'' is 17 km long transfers the production of six platforms of the Northeast Pole for the Garoupa Central platform in Campos' Basin. This pipeline works with a flowrate of 450 m{sup 3}/h and it began to operate in 1987. The existence of a non-piggable sub sea manifold 500 meters down stream PGP-1 allied with receiver's absence impeded the passage of any type of pigs. The strategic importance of the pipeline allied with the need of operational safety assurance took PETROBRAS/UN-BC to the decision of building a pigs receiver in PGP-1 and to reestablish pig ability assembling a new riser and a new sub sea pipeline covering 500 meters, both in the diameter of 22 inches. After the conclusion, it was carried out a long campaign of cleaning, with emphasis in the development new drawings of specific pigs for the removal of the internal debris accumulated since the beginning of the operation. Several accessories were developed in order to improve the removal and arresting of wax and barium sulfate scale. Finally, the pipeline was inspected with a high resolution MFL pig. The present work describes all the stages of this pipeline rehabilitation, from the adaptation of the submarine facilities and of surface, going by the extensive campaign of cleaning and culminated with the inspection and the evaluation of the integrity.

Pipeline oil fire detection with MODIS active fire products

Ogungbuyi, M. G.; Martinez, P.; Eckardt, F. D.

2017-12-01

We investigate 85 129 MODIS satellite active fire events from 2007 to 2015 in the Niger Delta of Nigeria. The region is the oil base for Nigerian economy and the hub of oil exploration where oil facilities (i.e. flowlines, flow stations, trunklines, oil wells and oil fields) are domiciled, and from where crude oil and refined products are transported to different Nigerian locations through a network of pipeline systems. Pipeline and other oil facilities are consistently susceptible to oil leaks due to operational or maintenance error, and by acts of deliberate sabotage of the pipeline equipment which often result in explosions and fire outbreaks. We used ground oil spill reports obtained from the National Oil Spill Detection and Response Agency (NOSDRA) database (see www.oilspillmonitor.ng) to validate MODIS satellite data. NOSDRA database shows an estimate of 10 000 spill events from 2007 - 2015. The spill events were filtered to include largest spills by volume and events occurring only in the Niger Delta (i.e. 386 spills). By projecting both MODIS fire and spill as `input vector' layers with `Points' geometry, and the Nigerian pipeline networks as `from vector' layers with `LineString' geometry in a geographical information system, we extracted the nearest MODIS events (i.e. 2192) closed to the pipelines by 1000m distance in spatial vector analysis. The extraction process that defined the nearest distance to the pipelines is based on the global practices of the Right of Way (ROW) in pipeline management that earmarked 30m strip of land to the pipeline. The KML files of the extracted fires in a Google map validated their source origin to be from oil facilities. Land cover mapping confirmed fire anomalies. The aim of the study is to propose a near-real-time monitoring of spill events along pipeline routes using 250 m spatial resolution of MODIS active fire detection sensor when such spills are accompanied by fire events in the study location.

Integral control for population management.

2015-04-01

We present a novel management methodology for restocking a declining population. The strategy uses integral control, a concept ubiquitous in control theory which has not been applied to population dynamics. Integral control is based on dynamic feedback-using measurements of the population to inform management strategies and is robust to model uncertainty, an important consideration for ecological models. We demonstrate from first principles why such an approach to population management is suitable via theory and examples.

We present the data reduction pipeline for CHARIS, a high-contrast integral-field spectrograph for the Subaru Telescope. The pipeline constructs a ramp from the raw reads using the measured nonlinear pixel response and reconstructs the data cube using one of three extraction algorithms: aperture photometry, optimal extraction, or χ2 fitting. We measure and apply both a detector flatfield and a lenslet flatfield and reconstruct the wavelength- and position-dependent lenslet point-spread function (PSF) from images taken with a tunable laser. We use these measured PSFs to implement a χ2-based extraction of the data cube, with typical residuals of ˜5% due to imperfect models of the undersampled lenslet PSFs. The full two-dimensional residual of the χ2 extraction allows us to model and remove correlated read noise, dramatically improving CHARIS's performance. The χ2 extraction produces a data cube that has been deconvolved with the line-spread function and never performs any interpolations of either the data or the individual lenslet spectra. The extracted data cube also includes uncertainties for each spatial and spectral measurement. CHARIS's software is parallelized, written in Python and Cython, and freely available on github with a separate documentation page. Astrometric and spectrophotometric calibrations of the data cubes and PSF subtraction will be treated in a forthcoming paper.

The report examines environmental issues related to hydrostatic testing of discharge waters generated from integrity testing of natural gas pipelines. Hydrostatic testing, and proper environmental management of the discharge waters, can be required by DOT regulations. However, disposal of water used to conduct a hydrostatic pipeline test is regulated on a state-by-state basis. State-specific requirements vary widely, ranging from an authorization letter to a complete NPDES permit. Monitoring may be required before and during discharge, include a variety of analyses, have varying protocols for obtaining samples, and may be required either to obtain data or to ascertain compliance with stipulated discharge limits. The composition of the discharge and state-specific discharge limitations dictate treatment needs on a case-by-case basis. The volume consists of the Executive Summary of a five-volume report series

Landslides have a serious impact on the integrity of oil and gas pipelines in the tough terrain of Western China. This paper introduces a solving method of axial stress, which uses numerical simulation and regression analysis for the pipelines subjected to landslides. Numerical simulation is performed to analyze the change regularity of pipe stresses for the five vulnerability assessment indexes, which are: the distance between pipeline and landslide tail; the thickness of landslide; the inclination angle of landslide; the pipeline length passing through landslide; and the buried depth of pipeline. A pipeline passing through a certain landslide in southwest China was selected as an example to verify the feasibility and effectiveness of this method. This method has practical applicability, but it would need large numbers of examples to better verify its reliability and should be modified accordingly. Also, it only considers the case where the direction of the pipeline is perpendicular to the primary slip direction of the landslide.

Our purpose is to focus on the Safety, Environment and Health (SEH) Management, integrated to pipeline construction and assembly, aiming at minimizing the risks involving the transportation and handling of 20-inch pipes. Please note that peculiar, challenging situations occur when constructing a gas pipeline at the Coari-Anama Section, which leads to some difficulty in the exploitation of oil and gas, where fragile elements represented by the environment and man are faced in this evolution and progress process. Overcoming the severe conditions while streaming 196.6-km-length of pipes in flooded lands no doubt represented a real challenge. State-of-the-art techniques have been implemented such as air transportation of pipes, with two large-sized helicopters being used (Kamov and S64 Skycrane). This has demanded integrated actions to be adopted, involving transportation of concrete pipes, double joints, pipesak, hydraulic excavators, net carrier containing assorted materials, skids and natural gas pressure, measurement and filtering equipment. Nevertheless, we have succeeded in reducing the rate of exposure to the construction and assembly process risks, thus minimizing occurrences and improving the conditions of processes, where, had the conventional method been used, would have led to a great amount of incidents and accidents, resulting mainly from the huge logistic difficulties, which would expose the task force to high potential risks.

The Committee for Long-Distance Pipelines (Berlin, Federal Republic of Germany) reported on the relation between deterministic and probabilistic approaches in order to contribute to a better understanding of the safety management of long-distance pipelines. The respective strengths and weaknesses as well as the deterministic and probabilistic fundamentals of the safety management are described. The comparison includes fundamental aspects, but is essentially determined by the special character of the technical plant 'long-distance pipeline' as an infrastructure project in the area. This special feature results to special operation conditions and related responsibilities. However, our legal system 'long-distance pipeline' does not grant the same legal position in comparison to other infrastructural facilities such as streets and railways. Thus, the question whether and in what manner the impacts from the land-use in the environment of long-distance pipelines have to be considered is again and again the initial point for the discussion on probabilistic and deterministic approaches.

Pipelines are considered to be the safest way for transportation of large amounts of liquid and gas over large distances. In the course of the lifetime of a pipeline, however, many effects can lead to damages affecting the integrity of the line, e.g. manufacturing-related anomalies, operationally induced anomalies or third-party damage. In order to avoid pipeline failures with potentially catastrophic consequences so-called intelligent pigs (or smart pigs) were developed during the last decades: These tools allow for the internal inspection (In-Line Inspection, ILI) of pipelines using non-destructive testing technologies for the early detection and sizing of defects. Most common are magnetic flux leakage (MFL) and ultrasonic techniques for corrosion inspection and the latter also for crack inspection. While the ultrasonic techniques offer superior sizing capabilities they are limited to the inspection of liquid pipelines where the medium itself provides the necessary coupling between the (piezoelectric) ultrasonic transducers and the pipe wall. However, this limitation can be overcome by recent developments using EMAT (Electro-Magnetic Acoustic Transducer) technology. By a special sensor design, the EMAT inspection is combined with eddy current (EC) inspection and MFL inspection at the same time. As a result, this new multi-technology approach offers improved sizing as well as enhanced feature identification for wall thickness inspection of gas pipelines. (orig.)

The blind faith deep water horizontal pipeline tie-in project

Energy Technology Data Exchange (ETDEWEB)

Charalambides, John Nicos [Oceaneering International, Inc., Houston, TX (United States)

2009-12-19

This presentation will concentrate on the design challenges, experience and learning from the SIT and offshore installation of two deepwater pipeline tie-ins using first-of-its-kind subsea technology and installation methodologies on the 'Blind Faith' project. The Blind Faith Subsea Tie-Ins join the Blind Faith oil and gas pipelines with the Canyon Chief gas pipeline and the Mountaineer oil pipeline in 5100 feet of water. Both of the Blind Faith oil and gas pipelines are terminated with conventional PLEMs providing a horizontal connector for the tie-in and a vertical connector for a future tie-in connection point. The connectors are ROV operable/installable clamp style connectors. The method of joining to the Canyon Chief oil and gas pipelines and the type of jumper employed are unique to the tie-in. An ROV operable / installable mechanical pipe end connector connects the bare ends of the Canyon Chief and Mountaineer pipelines. The mechanical pipe end connector is fitted with an integral clamp connector hub and rests on an ROV installed mud mat. After installation of the mechanical connector, metrology was performed to create a neutral state horizontal jumper for joining the mechanical connector hub and the Blind Faith PLEM. The neutral state horizontal jumper is a compliant 'Z-Bend' design. During installation the jumper was elastically pre-deformed using a bowstring system. Pre-deformation of the jumper provided installation clearances and facilitated the neutral stress state after installation. Once landed the jumper bowstring was relaxed, allowing the jumper to expand to fit between the hubs. After expansion and make-up, the clamp connectors were tightened via an ROV operated hydraulic torque wrench. A seal test verified the integrity of the connections. After installation the jumper remains in a minimal residual stress state atypical of most horizontal jumpers. The horizontal jumper was chosen over the vertical jumper because it provides a

Sonninskii, A V; Sirotin, A M; Vasiliev, Y N

1981-04-01

VNIIgaz has improved the conventional Japanese SECT pipeline-heating system, which uses a small steel tube that contains an insulated heater/conductor and is welded to the top of the pipeline. The improved version has two insulated electric heaters - one on the top and the other on the bottom of the pipeline - located inside steel angle irons that are welded to the pipeline. A comparison of experimental results from heating a 200-ft pipeline with both systems at currents of up to 470 A clearly demonstrated the better heating efficiency of the VNIIgaz unit. The improved SECT system would be suitable for various types of pipelines, including gas lines, in the USSR's far north regions.

The accelerated process of urbanization that is shifting the aspects of Brazilian cities - most clearly in South East and South region states - is inherently involved with decayed levels of quality of life and little or any concern at all with the sustainability of such urban expansion. Besides the social difficulties generated from this non-planned growth - mainly in the cities' outskirts - there are many questions related to urbanization that should be reconsidered such as water, soil and air pollution; lack of water resources; floods, insufficient public transport and traffic problems; urban infra-structure and lodging privations and inadequate soil installment. This paper aims at showing how this disordered urban growth plays an important role on PETROBRAS' pipeline right of way located at the great cities urban areas, more specifically the Urban Right Of Way that cross the metropolitan region of the city of Sao Paulo. Also, it is an objective to express how such urbanization propitiate the execution of basic infra-structure in a way of integrating habitation, sanitation, environment and geotechnical sectors with the purposes of PETROBRAS of maintaining as priority the integrity of the pipelines located on the ROW as well as the integrity of these ROW themselves.

Pietrak, T.; Rudzki, Z.; Surmacz, W.

2006-01-01

Technological units of the Transit Gas Pipeline (i.e. Compressor Stations, Valve Stations, Stations or National Network Service Installations) have been fitted with Ball Valves as shut-off devices (block valves). Internal tightness of the valves' seat becomes major factor in securing proper service conditions during normal pipeline operation as well as for isolating of pipeline sections in emergency situations (loss of pipeline integrity or uncontrolled gas escape). Internal tightness of the valves is being inspected during scheduled maintenance of the pipeline units. Any leak revealed during inspection is being repaired, following instructions provided in the Manufacturer's Valve Manual. After a time, some cases have been identified, when repair of the revealed leak was found to be difficult, despite close following of the repair manuals. The paper presents analysis of the issue and corrective actions taken accordingly. (authors)

Pipelines : moving biomass and energy

Energy Technology Data Exchange (ETDEWEB)

Kumar, A. [Alberta Univ., Edmonton, AB (Canada). Dept. of Mechanical Engineering

2006-07-01

Moving biomass and energy through pipelines was presented. Field sourced biomass utilization for fuel was discussed in terms of competing cost factors; economies of scale; and differing fuel plant sizes. The cost versus scale in a bioenergy facility was illustrated in chart format. The transportation cost of biomass was presented as it is a major component of total biomass processing cost and is in the typical range of 25-45 per cent of total processing costs for truck transport of biomass. Issues in large scale biomass utilization, scale effects in transportation, and components of transport cost were identified. Other topics related to transportation issues included approaches to pipeline transport; cost of wood chips in pipeline transport; and distance variable cost of transporting wood chips by pipeline. Practical applications were also offered. In addition, the presentation provided and illustrated a model for an ethanol plant supplied by truck transport as well as a sample configuration for 19 truck based ethanol plants versus one large facility supplied by truck plus 18 pipelines. Last, pipeline transport of bio-oil and pipeline transport of syngas was discussed. It was concluded that pipeline transport can help in reducing congestion issues in large scale biomass utilization and that it can offer a means to achieve large plant size. Some current research at the University of Alberta on pipeline transport of raw biomass, bio-oil and hydrogen production from biomass for oil sands and pipeline transport was also presented. tabs., figs.

An analysis of perceptions and awareness of risk associated with energy pipelines in South Africa

Tatenda Mbara

2011-11-01

Full Text Available Worldwide, there has been a rapid growth in the use of pipelines to transport energy products. Due to the strategic nature of energy products that are transported by pipelines, the importance of risk awareness, assessment and management cannot be over-emphasised. With the risk of pipeline disruptions increasing globally, energy pipeline organisations are compelled to incorporate measures that should help to identify and address areas that can lead to energy pipeline disruptions. The incorporation of such measures for any organisation is premised on an understanding and appreciation of the risks involved. Given the strategic importance of energy pipelines, the main purpose of this paper is to establish whether the South African energy pipeline sector and the public at large appreciate the risks associated with energy pipelines. Thus, the paper seeks to ascertain awareness of the risks associated with the energy pipeline's physical environment, not only from the energy pipeline operators, but also from communities who are exposed to such risks. Data for the study was collected from energy pipeline operators and from a selected residential area in Johannesburg using both structured and unstructured questionnaires. The findings show that the corporate energy sector in South Africa is aware of risks associated with energy pipeline supply chains while the general public's awareness is very low.

Integrating semantic information into legacy metadata catalogs is a challenging issue and so far has been mostly done on a limited scale. We present experience of CINERGI (Community Inventory of Earthcube Resources for Geoscience Interoperability), an NSF Earthcube Building Block project, in creating a large cross-disciplinary catalog of geoscience information resources to enable cross-domain discovery. The project developed a pipeline for automatically augmenting resource metadata, in particular generating keywords that describe metadata documents harvested from multiple geoscience information repositories or contributed by geoscientists through various channels including surveys and domain resource inventories. The pipeline examines available metadata descriptions using text parsing, vocabulary management and semantic annotation and graph navigation services of GeoSciGraph. GeoSciGraph, in turn, relies on a large cross-domain ontology of geoscience terms, which bridges several independently developed ontologies or taxonomies including SWEET, ENVO, YAGO, GeoSciML, GCMD, SWO, and CHEBI. The ontology content enables automatic extraction of keywords reflecting science domains, equipment used, geospatial features, measured properties, methods, processes, etc. We specifically focus on issues of cross-domain geoscience ontology creation, resolving several types of semantic conflicts among component ontologies or vocabularies, and constructing and managing facets for improved data discovery and navigation. The ontology and keyword generation rules are iteratively improved as pipeline results are presented to data managers for selective manual curation via a CINERGI Annotator user interface. We present lessons learned from applying CINERGI metadata augmentation pipeline to a number of federal agency and academic data registries, in the context of several use cases that require data discovery and integration across multiple earth science data catalogs of varying quality

Pipelines to eastern Canada

1998-01-01

This presentation focused on four main topics: (1) the existing path of pipelines to eastern Canada, (2) the Chicago hub, (3) transport alternatives, and (4) the Vector Pipeline' expansion plans. In the eastern Canadian market, TransCanada Pipelines dominates 96 per cent of the market share and is effectively immune to expansion costs. Issues regarding the attractiveness of the Chicago hub were addressed. One attractive feature is that the Chicago hub has access to multiple supply basins including western Canada, the Gulf Coast, the mid-continent, and the Rockies. Regarding Vector Pipelines' future plans, the company proposes to construct 343 miles of pipeline from Joliet, Illinois to Dawn, Ontario. Project description included discussion of some of the perceived advantages of this route, namely, extensive storage in Michigan and south-western Ontario, the fact that the proposed pipeline traverses major markets which would mitigate excess capacity concerns, arbitrage opportunities, cost effective expansion capability reducing tolls, and likely lower landed costs in Ontario. Project schedule, costs, rates and tariffs are also discussed. tabs., figs

In 2007, several important initiatives in the North American waterfowl management community called for an integrated approach to habitat and harvest management. The essence of the call for integration is that harvest and habitat management affect the same resources, yet exist as separate endeavours with very different regulatory contexts. A common modelling framework could help these management streams to better understand their mutual effects. Particularly, how does successful habitat management increase harvest potential? Also, how do regional habitat programmes and large-scale harvest strategies affect continental population sizes (a metric used to express habitat goals)? In the ensuing five years, several projects took on different aspects of these challenges. While all of these projects are still on-going, and are not yet sufficiently developed to produce guidance for management decisions, they have been influential in expanding the dialogue and producing some important emerging lessons. The first lesson has been that one of the more difficult aspects of integration is not the integration across decision contexts, but the integration across spatial and temporal scales. Habitat management occurs at local and regional scales. Harvest management decisions are made at a continental scale. How do these actions, taken at different scales, combine to influence waterfowl population dynamics at all scales? The second lesson has been that consideration of the interface of habitat and harvest management can generate important insights into the objectives underlying the decision context. Often the objectives are very complex and trade-off against one another. The third lesson follows from the second – if an understanding of the fundamental objectives is paramount, there is no escaping the need for a better understanding of human dimensions, specifically the desires of hunters and nonhunters and the role they play in conservation. In the end, the compelling question is

2015-06-01

Full Text Available The integration of health and safety, environmental and quality (HSEQ management systems has become a current topic in the 21st century, as the need for systems thinking has grown along with the number of management system standards. This study aims to map current developments and trends in integrated HSEQ management. Three viewpoints are taken: the current state of the main HSEQ management standards, research literature on integrated management systems (IMS, and a case study of an industry-led HSEQ cluster in Northern Finland. The results demonstrate that some of the most prominent current trends are the harmonization of the high level structure of management systems by ISO, the evaluation of IMS, accounting for the supply chain in HSEQ issues, and sustainability and risk management. The results of the study can be used by practitioners to get a view of the current state of HSEQ management systems and their integration, and by researchers to seek out potential directions for HSEQ and IMS related research.

Transforming microbial genotyping: a robotic pipeline for genotyping bacterial strains.

Directory of Open Access Journals (Sweden)

Brian O'Farrell

Full Text Available Microbial genotyping increasingly deals with large numbers of samples, and data are commonly evaluated by unstructured approaches, such as spread-sheets. The efficiency, reliability and throughput of genotyping would benefit from the automation of manual manipulations within the context of sophisticated data storage. We developed a medium- throughput genotyping pipeline for MultiLocus Sequence Typing (MLST of bacterial pathogens. This pipeline was implemented through a combination of four automated liquid handling systems, a Laboratory Information Management System (LIMS consisting of a variety of dedicated commercial operating systems and programs, including a Sample Management System, plus numerous Python scripts. All tubes and microwell racks were bar-coded and their locations and status were recorded in the LIMS. We also created a hierarchical set of items that could be used to represent bacterial species, their products and experiments. The LIMS allowed reliable, semi-automated, traceable bacterial genotyping from initial single colony isolation and sub-cultivation through DNA extraction and normalization to PCRs, sequencing and MLST sequence trace evaluation. We also describe robotic sequencing to facilitate cherrypicking of sequence dropouts. This pipeline is user-friendly, with a throughput of 96 strains within 10 working days at a total cost of 200,000 items were processed by two to three people. Our sophisticated automated pipeline can be implemented by a small microbiology group without extensive external support, and provides a general framework for semi-automated bacterial genotyping of large numbers of samples at low cost.

Risk analysis for construction and operation of gas pipeline projects in pakistan

International Nuclear Information System (INIS)

Mubin, S.; Mubin, G.

2008-01-01

In order to cater for its high energy demand, Pakistan is planning to import natural gas through pipelines from neighboring countries. For fully utilizing the imported gas, providing it to end customers, the infrastructure of gas pipeline needs to be developed. Therefore, huge investment has been done and proposed in this sector in coming future. Considering geological, topographical, geopolitical and climatic conditions of the country, there is added risk of earthquake, landslides and floods. Due to current geopolitical situation there is a persistent threat of unrest and terrorism in the country. Instable Government policies, high rate of inflation, rapid change in material prices are also important risk factors. All these factors make the situation very complex in quantifying the risk especially for a project in which the risk impact factor rises exponentially in case of risk occurrence. In this paper, most appropriate risk classification is made based on technological, organizational, political, natural climatic, security and environmental risk factors. Effort has been made to device a simpler risk management methodology to analyze and manage risks of gas pipeline project. In the proposed risk management model Monte Carlo simulation has been used to identify critical risks. (author)

Multi-attribute risk assessment for risk ranking of natural gas pipelines

International Nuclear Information System (INIS)

Brito, A.J.; Almeida, A.T. de

2009-01-01

The paper presents a decision model for risk assessment and for risk ranking of sections of natural gas pipelines based on multi-attribute utility theory. Pipeline hazard scenarios are surveyed and the reasons for a risk assessment model based on a multi-attribute approach are presented. Three dimensions of impact and the need to translate decision-makers' preferences into risk management decisions are highlighted. The model approaches these factors by using a multi-attribute utility function, in order to produce multi-dimensional risk measurements. By using decision analysis concepts, this model quantitatively incorporates the decision-maker's preferences and behavior regarding risk within clear and consistent risk measurements. In order to support the prioritizing of critical sections of pipeline in natural gas companies, this multi-attribute model also allows sections of pipeline to be ranked into a risk hierarchy. A numerical application based on a real case study was undertaken so that the effectiveness of the decision model could be verified

Leakage is an important factor to be considered for the management of underground water supply pipelines in a smart water grid system, especially if the pipelines are aged and buried under the pavement or various structures of a highly populated city. Because the exact detection of the location of such leaks in pipelines is essential for their efficient operation, a new methodology for leak location detection based on frequency band variation, windowing filters, and probability is proposed in this paper. Because the exact detection of the leak location depends on the precision of estimation of time delay between sensor signals due to leak noise, some window functions that offer weightings at significant frequencies are applied for calculating the improved cross-correlation function. Experimental results obtained by applying this methodology to an actual buried water supply pipeline, ∼ 253.9 m long and made of cast iron, revealed that the approach of frequency band variation with those windows and probability offers better performance for leak location detection.

This paper discussed a pipeline integrity analysis for a buried crude-oil pipeline at a site characterized by unstable permafrost slopes. Data collected from piezometers, inclinometers, and thermistor cables installed as part of a comprehensive geotechnical monitoring program were used to determine the geotechnical character of the site and model pipe/soil interactions. A finite element pipe/soil interaction model was developed to estimate the potential strain to the pipeline capacity in a worst-case scenario involving mass soil movement. The purpose was to determine the necessity of costly mitigation measures. The model showed that the pipeline strain capacity is unlikely to be exceeded in the event of a sudden ground movement at the slope. The soil, permafrost, and slope movement conditions at the site were described along with the methodology and results of the pipe/soil interaction model. The model, in which the pipeline is considered as a continuous structural beam, was used to analyze both the estimated current slope movement and the worst case large magnitude slope movement. To assess the pipeline integrity in the event of mass slope movement, the expected strain demand was compared to the strain capacity, taking into account whether the pipe is heavy wall, line pipe, or containing girth welds. The analysis indicated that the risk of pipeline failure is low in the event of a large magnitude slope movement. The pipe strain measurements were found to be within the design limits for the pipeline. The analysis is relevant to other northern pipeline and linear infrastructure developments. 8 refs., 6 figs.

Effective management of area-wide integrated pest management (AW-IPM) programmes that integrate the sterile insect technique (SIT) is key to success. Programme planning includes collection of baseline data and a feasibility assessment. The optimal management structure is where the programme can be implemented effectively and flexibly, independent of government politics, bureaucracy, and even corruption that impede timely goal achievement. Ideally, programmes include both public and private management, and require strong and steady financial support. Governments and donors are the most common sources of funds, but a mixture of public, community, and private funds is now the trend. Interrupted cash flow severely restrains programme performance. Physical support of programme operations must be reliable, and led by a maintenance professional. It is essential to have full-time, well-paid, and motivated staff led by a programme manger with technical and management experience. Programme failure is usually due to poor management and inadequate public support, and not to poor technology. (author)

Pipeline corrosion prevention by pH stabilization or corrosion inhibitors

Nyborg, Rolf [Institute for Energy Technology, Oslo (Norway)

2009-07-01

In many offshore oil and gas projects the pipeline costs are a considerable part of the investment and can become prohibitively high if the corrosivity of the fluid necessitates the use of corrosion resistant alloys instead of carbon steel. Development of more robust and reliable methods for internal corrosion control can increase the application range of carbon steel and therefore have a large economic impact. Corrosion control of carbon steel pipelines has traditionally often been managed by the use of corrosion inhibitors. The pH stabilization technique has been successfully used for corrosion control of several large wet gas pipelines in the last years. This method has advantages over film forming corrosion inhibitors when no or little formation water is produced. The use of corrosion inhibitors in multiphase pipelines implies several challenges which are not fully accounted for in traditional corrosion inhibitor testing procedures. Specialized test procedures have been developed to take account for the presence of emulsions dispersions and sand and clay particles in corrosion inhibitor testing. (author)

The pipeline transportation applying risks assessment issue in the arctic conditions is addressed in the paper. Pipeline quality characteristics in the given environment has been assessed. To achieve the stated objective, the pipelines mathematical model was designed and visualized by using the software product SOLIDWORKS. When developing the mathematical model the obtained results made possible to define the pipeline optimal characteristics for designing on the Arctic sea bottom. In the course of conducting the research the pipe avalanche collapse risks were examined, internal longitudinal and circular loads acting on the pipeline were analyzed, as well as the water impact hydrodynamic force was taken into consideration. The conducted calculation can contribute to the pipeline transport further development under the harsh climate conditions of the Russian Federation Arctic shelf territory.

The concept of integrated project management represents a single source to which the owner can turn for all project management functions excepting for those relating to outside parties such as site purchase, personnel selection etc. Other functions such as design, procurement, construction management, schedule and cost control, quality assurance/quality control are usually handled by the integrated project manager as the agent of the owner. The arrangement is flexible and the responsibilities can be varied to suit the size and experience of the owner. Past experience in the United States indicates an increase in the trend toward IPM work and it appears that overseas this trend is developing also. (orig./RW) [de

Full Text Available Background: The research work on entrepreneurship, enterprise's policy and management, which started in 1992, successfully continued in the following years. Between 1992 and 2011, more than 400 academics and other researchers have participated in research work (MER research program whose main orientation has been the creation of their own model of integral management. Results: In past years, academics (researchers and authors of published papers from Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Byelorussia, Canada, the Czech Republic, Croatia, Estonia, France, Germany, Hungary, Italy, Poland, Romania, Russia, the Slovak Republic, Slovenia, Switzerland, Ukraine, and the US have cooperated in MER programs, coming from more than fifty institutions. Thus, scientific doctrines of different universities influenced the development of the MER model which is based on both horizontal and vertical integration of the enterprises' governance and management processes, instruments and institutions into a consistently operating unit. Conclusions: The presented MER model is based on the multi-layer integration of governance and management with an enterprise and its environment, considering the fundamental desires for the enterprises' existence and, thus, their quantitative as well as qualitative changes. The process, instrumental, and institutional integrity of the governance and management is also the initial condition for the implementation of all other integration factors.

Slurry pipeline design approach

2009-12-19

Compared to other engineering technologies, the design of a commercial long distance Slurry Pipeline design is a relatively new engineering concept which gained more recognition in the mid 1960 's. Slurry pipeline was first introduced to reduce cost in transporting coal to power generating units. Since then this technology has caught-up worldwide to transport other minerals such as limestone, copper, zinc and iron. In South America, the use of pipeline is commonly practiced in the transport of Copper (Chile, Peru and Argentina), Iron (Chile and Brazil), Zinc (Peru) and Bauxite (Brazil). As more mining operations expand and new mine facilities are opened, the design of the long distance slurry pipeline will continuously present a commercially viable option. The intent of this paper is to present the design process and discuss any new techniques and approach used today to ensure a better, safer and economical slurry pipeline. (author)

The article describes the experience of the area of Social Responsibility in TRANSPETRO, a wholly Brazilian Subsidiary of PETROBRAS, which operates in the field of transport of petroleum, its by-products and gas, by way of oil and gas pipeline networks. Pipeline is the safety option for the transport of these products, but requires monitoring and the permanent management of the use and occupation of the soil and surrounding area. This care does not only depend on the Company as responsibility is much wider. Active participation by the communities affected by the operations is essential, principally in incorporating the rules of occupation and the use of the soil in the land surrounding the strips and the terminals. This participation is justified given that the action of third parties represents a significant proportion (70%) of the irregular situations registered by the Company. Community Relationship Management is one of the principal strategies to increase the safety of the pipelines integrated into the Company's programs of maintenance and operational control. Therefore, a plan of Community Relations has been implanted, focusing on the transformation of values to construct a community culture of co-habitation and co-responsibility for the pipeline land.

Full Text Available The present article deals with integrated research works and tests of pipeline supports for the areas of above-ground routing of the pipeline system “Zapolyarye - Pur-pe” which is laid in the eternally frozen grounds. In order to ensure the above-ground routing method for the oil pipeline “Zapolyarye - Pur-pe” and in view of the lack of construction experience in case of above-ground routing of oil pipelines, the leading research institute of JSC “Transneft” - LLC “NII TNN” over the period of August, 2011 - September, 2012 performed a research and development work on the subject “Development and production of pipeline supports and pile foundation test specimens for the areas of above-ground routing of the pipeline system “Zapolyarye - Pur-pe”. In the course of the works, the test specimens of fixed support, linear-sliding and free-sliding pipeline supports DN1000 and DN800 were produced and examined. For ensuring the stable structural reliability of the supports constructions and operational integrity of the pipelines the complex research works and tests were performed: 1. Cyclic tests of structural elements of the fixed support on the test bed of JSC “Diascan” by means of internal pressure and bending moment with the application of specially prepared equipment for defining the pipeline supports strength and durability. 2. Tests of the fixed support under the influence of limit operating loads and by means of internal pressure for confirming the support’s integrity. On the test bed there were simulated all the maximum loads on the support (vertical, longitudinal, side loadings, bending moment including subsidence of the neighboring sliding support and, simultaneously, internal pressure of the carried medium. 3. Cyclic tests of endurance and stability of the displacements of sliding supports under the influence of limit operating loads for confirming their operation capacity.

European Union is interested also like USA to lower its own dependence on oil distributors from problematic region of Persian Gulf. Therefore the attention is turning on to Russia and to region of Caspian Sea. However except political and safety problems the import of oil from these territories meets also the lack of transport capacities. Slovakia can become the important transit territory, where could flow more Russian or Caspian oil to the European market. After a break-up of Soviet Union Russia lost oil export terminals on the coast of Baltic Sea. These terminals became a part of territories of three independent Baltic countries. The frequent storms in the region of Novorossiysk are disadvantage of Black Sea's ports Novorossiysk and Tuapse. The overloading of Turkish straits Bospor and Dardanely, which connect Black Sea and Mediterranean Sea, is becoming a new and more serious problem. In the present time up to 500 tankers swim over through these straits annually, which transport together around 70 million tones of oil and of oil products. Owing to the rising mining of oil the only one way out is the circumvention of these straits. New pipeline from Baku through Georgia to Turkish terminal Ceyhan on the coast of Mediterranean Sea is the only one but not sufficient solution. Therefore Russia promotes the project of integration of pipelines Druzba and Adria. The intensions is to open the continuous export pipeline way through Belarus, Ukraine, Slovakia and Hungary into Croatian terminal Omisajl on the coast of Adriatic Sea. Other possibility how to rise the oil transit through Slovakia is the construction of pipeline to the refinery OMW in Schweechat near Vienna. In the end of the last year the representatives of Transpetrol, Yukos and OMW signed the contract of its construction in Bratislava. Annual capacity of this pipeline is 2 million tonnes of oil. Other possibility how to transport the Caspian oil is pipeline Odessa-Brody. More then 600 km of this pipeline

Integrated management of waterbirds: Beyond the conventional

Integrated waterbird management over the past few decades has implicitly referred to methods for managing wetlands that usually attempt to enhance habitat for taxonomic groups such as shorebirds and wading birds, in addition to waterfowl, the traditional focus group. Here I describe five elements of integration in management: taxonomic, spatial, temporal, population and habitat, and multiple-use management objectives. Spatial integration simply expands the scale of management concern. Rather than emphasizing management on a very limited number of impoundments or wetlands in small refuges or wildlife management areas, the vision is beginning to shift to connectivity within larger landscapes on the order of many square kilometers as telemetry data on daily and seasonal movements for many species become available. Temporal integration refers to the potential for either simultaneous management for waterbirds and commercial 'crops' (e.g., crayfish and rice) or for temporally-staggered management such as row crop production in spring-summer growing seasons and waterbird management on fallow fields in the non-growing (winter) season. Integrating population dynamics with habitats has become a major research focus over the past decade. Identifying which wetlands are ?sources? or ?sinks? for specific populations provides managers with critical information about effective management. Further, the applications of spatially explicit population models place heavy demands on researchers to identify use patterns for breeding and dispersing individuals by age, sex, and reproductive class. Population viability analysis models require much the same information. Finally, multiple-use management integration refers to trying to optimize the uses of wetlands, when only one (perhaps secondary) use may include waterbird management. Depending upon the ownership and primary land use of a particular parcel of land containing wetlands and/or water bodies, managing for waterbirds may be an

PETROBRAS has been conducting several wildlife programs in response to environmental licensing requirements from IBAMA (Brazilian environmental agency). Since 2007, IBAMA has been requiring the application of the Normative Instruction n. 146 (NI), which establishes criteria for wildlife management in the influence areas of new enterprises. However, experience from PETROBRAS has shown that many of the NI articles are not applicable to pipelines. Thus, a critical analysis of this NI was done based on data from company's wildlife programs. Our analysis indicated that the main NI items that do not apply to pipelines are: 1 - Animal rescue programs in deforested areas and selection of release areas, 2 - More than two fauna monitoring campaigns a year, 3 - Monitoring programs involving all groups of terrestrial vertebrates and also invertebrate classes. The non-applicability of these items is due to: 1 - The majority of pipelines are built in areas without significant native vegetation or with small fragments only, which are usually in secondary stage of ecological succession. Most pipelines scarcely involve removal of primary vegetation, 2 - Pipelines have an influence area restricted to a range of 800 m and the construction directly affects only strips from 20 m to 30 m, 3 - The most relevant impacts associated with pipelines are temporary, and do not persist during their operation.

LNG transport through pipelines

Pfund, P; Philipps, A

LNG pipelines could help solve some peakshaving problems if operated in conjunction with other facilities that could use the LNG cold recovered during regasification. In some areas at present, LNG is delivered by tanker and regasified near the terminal for transmission through conventional gas pipelines. In other places, utilities liquefy natural gas for easy storage for later peakshaving use. The only chance to avoid the second expensive liquefaction step would be to convey imported LNG through a suitable designed LNG pipeline. The technical problems involved in LNG pipeline construction have basically been solved in recent years, but those pipelines actually constructed have been only short ones. To be economically justified, long-distance LNG lines require additional credit, which could be obtained by selling the LNG cold recovered during regasification to industrial users located in or near the points of gas consumption. Technical details presented cover the pipe material, stress relief, steel composition, pressure enthalpy, bellows-type expansion joints, and mechanical and thermal insulation.

The existing interstate pipelines and proposed pipeline projects for the Chicago hub area were illustrated. The presentation explained why energy suppliers in the current competitive market need to balance and manage energy and transportation services for gas-fired power generators in terms of hourly winter and summer peaking services. The new infrastructure of the energy market will include new pipelines, storage and balancing to meet the ever increasing power demand. One of the options to meet power demand is to increase natural gas supply, transportation, storage, and hourly balancing capabilities. Other options are to build nuclear or coal-fired power generating facilities, or to go with renewables such as solar and wind power. Energy conservation and the reduction of natural gas usage per capita is another option to eliminate blackouts. This presentation also addressed the role that local distribution companies (LDC) and unbundling will play in the choice of these options. tabs., figs

The Integrated Materials Management System, when fully implemented, will provide the Y-12 National Security Complex with advanced inventory information and analysis capabilities and enable effective assessment, forecasting and management of nuclear materials, critical non-nuclear materials, and certified supplies. These capabilities will facilitate future Y-12 stockpile management work, enhance interfaces to existing National Nuclear Security Administration (NNSA) corporate-level information systems, and enable interfaces to planned NNSA systems. In the current national nuclear defense environment where, for example, weapons testing is not permitted, material managers need better, faster, more complete information about material properties and characteristics. They now must manage non-special nuclear material at the same high-level they have managed SNM, and information capabilities about both must be improved. The full automation and integration of business activities related to nuclear and non-nuclear materials that will be put into effect by the Integrated Materials Management System (IMMS) will significantly improve and streamline the process of providing vital information to Y-12 and NNSA managers. This overview looks at the kinds of information improvements targeted by the IMMS project, related issues, the proposed information architecture, and the progress to date in implementing the system.

Full Text Available Rapid urbanization and industrialization, population growth and economic growth in developing countries make management of municipal solid waste more complex comparing with developed countries. Furthermore, the conventional municipal solid waste management approach often is reductionists, not tailored to handle complexity. Therefore, the need to a comprehensive and multi-disciplinary approach regarding the municipal solid waste management problems is increasing. The concept of integrated solid waste management is accepted for this aim all over the world. This paper analyzes the current situation as well as opportunities and challenges regarding municipal solid waste management in Isfahan according to the integrated solid waste management framework in six aspects: environmental, political/legal, institutional, socio-cultural, financial/economic, technical and performance aspects. Based on the results obtained in this analysis, the main suggestions for future integrated solid waste management of Isfahan are as i promoting financial sustainability by taking the solid waste fee and reducing the expenses through the promoting source collection of recyclable materials, ii improving compost quality and also marketing the compost products simultaneously, iii promoting the private sector involvements throughout the municipal solid waste management system.

Full Text Available Purpose. The goal of the paper is to discuss the potential benefits and to highlight the drawbacks of integrated management system for organizations that seek to improve management process.Methodology. Methods of the research were used: analysis of a scientific and special literature that presents the requirements, models and results of integrated management systems studies, and analysis of statistical data to assess actuality of integrated management systems for enterprises in Lithuania.Findings. Summarizing research findings, it should be stated that the implementation of management system integration should be based on provision of social responsibility and holistic approach to the organization. It requires the long-term united efforts of leaders in a strategic hierarchical level and high organizational maturity to ensure the fluency of the running stages of planning management system integration, preparing documentations, implementing and realizing integrated management system. Also it is necessary to purify the conception of integrated management system in organizational context. Theoretical analysis of integrated management systems show, that all of the management systems can not be well integrated in principle. They can only be partly integrated and coordinated. A need to question the level of integration of management systems is very important as in scientific discourse as in practice. It is important to mark, that the number of organizations, that seek to optimize management processes by implementing the integrated management systems is rapidly increasing in Lithuania, too. It shows that benefit associated with integration of management systems is apprehensible in Lithuania. Advantages of integrated management systems can certainly become even stronger if scientists and practicians join their forces in search of methods of organizational management development.Research limitations.

The Research and Special Programs Administration administers the Natural Gas Pipeline Safety Act of 1968 (NGPSA) and the Hazardous Liquid Pipeline Safety Act of 1979 (HLPSA). The RSPA issues and enforces design, construction, operation and maintenance regulations for natural gas pipelines and hazardous liquid pipelines. This paper discusses a number of proposed and pending safety regulations and legislative initiatives currently being considered by the RSPA and the US Congress. Some new regulations have been enacted. The next few years will see a great deal of regulatory activity regarding natural gas and hazardous liquid pipelines, much of it resulting from legislative requirements. The office of Pipeline Safety is currently conducting a study to streamline its operations. This study is analyzing the office's business, social and technical operations with the goal of improving overall efficiency, effectiveness, productivity and job satisfaction to meet the challenges of the future
