. Monetization of externalities can significantly enhance the value of a pipeline to society. In this study, a pipeline with a construction cost of $1.37 million/km in 2014 USD and a NPV of revenue over 22.2 years of $1.85 million/km would be associated with $0.5–$1.3 million/km in avoided negative externalities—the majority of which are expected from avoided air pollution-related deaths ($0.26–$1.0 million/km) and avoided GHG emissions ($0.12–$0.19 million/km).

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.

Focus on safety : a comparative analysis of pipeline safety performance 2000-2002
International Nuclear Information System (INIS)
2004-01-01
Canada's National Energy Board (NEB) is responsible for the promotion of safety, environmental protection and economic efficiency in the Canadian public interest in regulating the design, construction, operation and abandonment of interprovincial and international pipelines within Canada. This second annual report provides a review of the safety performance of oil and gas pipeline companies that are regulated by the NEB. The data used to prepare this report originates from two sources: incident reports submitted under the Onshore Pipeline Regulations, 1999, and from information voluntarily provided by pipeline companies under the Safety Performance Indicators (SPI) initiative. Data comparisons with external reference organizations were included. Six key indicators have been identified to provide comprehensive measures of safety performance for pipeline companies: fatalities, ruptures, injury frequencies, liquid releases, gas releases, and unauthorized activities on the right of way. The safety performance of the federally regulated pipeline industry within Canada was satisfactory during this reporting period (2000-2002). The contractor injury frequency rates reported in 2002 were lower than those reported in 2001, and exhibited more consistency with the levels reported in 2000. The NEB is of the opinion that the elevated number of liquid hydrocarbon spills reported in 2000 were a result of elevated construction levels. No fatalities were reported. There was an increase to three from two in the number of ruptures, due in large part to metal loss (corrosion) and cracking, and external interference (third party damage). The number of spills increased to 76 in 2002 from 55 in 2001, which appears to be more in line with industry averages. The volume of hydrocarbon liquid released in 2002 represented one third the volume released in 2001. refs., 5 tabs., 14 figs

Increase of ecological safety of the pipeline
International Nuclear Information System (INIS)
Dr Movsumov, Sh.N.; Prof Aliyev, F.G.
2005-01-01
Full text : For increase of ecological safety of the pipeline, necessary decrease of damage (risk) rendered by the pipeline on surrounding natural environment which depends: on the frequency of damage of the pipeline; on the volume poured oil; on the factor of sensitivity of an environment where flood of oil was. Frequency of damage of the pipeline depends on physico-chemical properties of a material of the pipeline, from its technical characteristics (thickness of a wall, length of a pipe, working pressure), on the seismic area of the district where the pipeline passed and also on the way of lining of the pipeline (underground or overground). The volume poured oil depends on diameter of the received damage, from stability of the pipeline mechanical and other external actions, from an ambient temperature, from capacity of the pipeline, from distance between the latches established in the pipeline, and also from time, necessary for their full closing. The factor of sensitivity of environment depends on geological structure and landscapes of district (mountain, the river, settlements) where passed the pipeline. At designing the pipeline, in report is shown questions of increase of ecological safety of the pipeline are considered at his construction and exploitation. For improvement of ecological safety of the pipeline is necessary to hold the following actions: Ecological education of the public, living near along a line of the oil pipeline; carrying out ecological monitoring; working of the public plan of response to oil spills; For ecological education of the public is necessary: carrying out informing of the public for all (technical, ecological, social and economic and legal) questions connected to an oil pipeline, and also on methods of protection of the rights at participation in acceptance of ecological significant decisions; Creation of public groups for realization of activity on observance of the legislation and to prevention of risks; Exposure of hot

2002-01-01
The transportation of natural gas, oil and other commodities is effected by pipelines throughout most of the country. Safety in the vicinity of a pipeline is very important because damage to a pipeline could result in adverse conditions to public safety and/or the environment. Before digging, written approval must be obtained from the pipeline company. If a landowner is having difficulty negotiating an agreement with the pipeline company, they should call the National Energy Board. It is illegal to construct or excavate without authorization, and approval or denial of a request must be granted within 10 business days by the pipeline company. Three days are allowed to the pipeline company to locate its pipeline. A section dealing with pipeline right-of-way is included, as well as the safety zone and the restricted area. A 10-step checklist of safety tips assists the landowner in taking the appropriate measures in the vicinity of a pipeline. A brief overview of the responsibilities of the National Energy Board is provided, followed by a list of the main pipelines regulated by the National Energy Board. 2 figs

Geospatial informatics applications for assessment of pipeline safety and security
Energy Technology Data Exchange (ETDEWEB)
Roper, W. [George Mason University, Fairfax, VA (United States). Dept. of Civil, Environmental and Infrastructure
2005-07-01
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.

Report of study group 4.3 ''pipeline integrity management and safety''
Energy Technology Data Exchange (ETDEWEB)
Clavel, P.
2000-07-01
This report highlights the Pipeline integrity Management methods being implemented by gas companies. These aim at maintaining the current high safety level, prevent major hazards, ensure the integrity of the pipeline and protect people and environment in the vicinity of the pipeline in the most cost effective way. It should be noticed that Pipeline Integrity Management aspects, technical and organisational, are included in the more general framework of the Safety Management System. Currently, more and more gas companies implement such a system on the basis of standards like ISO 9000 and so on. In this way, the report shows how practices of Pipeline Integrity Management are continually developing in order to adapt to their environment, and to improve performance. Past experience and imminent developments show that Pipeline Integrity Management is a flexible and efficient approach to improve safety in the long term. Consequently, Pipeline Integrity Management Systems are, under the control of authorities, the best alternative to additional safety regulations. Within the context of deregulation of the European markets and globalization Pipeline Integrity Management appears to be a tool to promote the gas industry in the eyes of the authorities, the market regulators and the customers (industrialists,...).

Safety installation for preventing pollution by pipelines
Energy Technology Data Exchange (ETDEWEB)
Wittgenstein, G F
1972-10-25
A safety installation for preventing pollution by pipelines, particularly those used for transporting liquid hydrocarbons, is described. It is applicable to any pipeline, but particularly to underground or submarine pipelines, whether made of steel, plastics, or any other material. The 4 essential objects of the invention are to insure reliable prevention of pollution of the environment due to leakage of a hydrocarbon through cracks in the pipe; to evacuate the leakage flow without delay to a vessel; to signal almost instantaneously the existence of a leak; and to effect remote control of operations by which the dynamic pressure in the pipe is cancelled. Each equipped section consists of a fluid-type jacket of plastic material which surrounds the pipe, which at its ends is sealed off. It is these seals which delimit the sections. (7 claims)

Natural-gas pipeline accidents mostly result in major damage even to buildings located far away. Therefore, proper safety distances should be observed in land use planning to ensure target safety levels for both existing and new buildings. In this paper, a quantitative risk assessment procedure is presented for the estimation of the annual probability of direct structural damage to reinforced concrete buildings associated with high-pressure natural-gas pipeline explosions. The procedure is based on Monte Carlo simulation and takes into account physical features of blast generation and propagation, as well as damage to reinforced concrete columns. The natural-gas jet release process and the flammable cloud size are estimated through SLAB one-dimensional integral model incorporating a release rate model. The explosion effects are evaluated by a Multi-Energy Method. Damage to reinforced concrete columns is predicted by means of pressure–impulse diagrams. The conditional probability of damage was estimated at multiple pressure–impulse levels, allowing blast fragility surfaces to be derived at different performance limit states. Finally, blast risk was evaluated and allowed the estimation of minimum pipeline-to-building safety distances for risk-informed urban planning. The probabilistic procedure presented herein may be used for performance-based design/assessment of buildings and to define the path of new natural-gas pipeline networks. - Highlights: • The safety of buildings against blast loads due to pipeline accidents is assessed. • A probabilistic risk assessment procedure is presented for natural-gas pipelines. • The annual risk of collapse of reinforced concrete building columns is evaluated. • Monte Carlo simulation was carried out considering both pipeline and column features. • A risk-targeted safety distance is proposed for blast strength class 9.

Distributed fiber optic sensing enhances pipeline safety and security
Energy Technology Data Exchange (ETDEWEB)
Frings, Jochen; Walk, Tobias [ILF Consulting Engineers, Munich (Germany)
2011-09-15
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.

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.

The transport of materials in pipelines is continuously increasing worldwide. Pipelines are one of the most economic and safe transport systems in all directions. In order to ensure this, not only new pipelines but also existing pipelines have to be kept up to date technically. Leakages are a possible safety risk. Leaks are manifold and range from earth quakes, corrosion or material fatigue up to open-up by drilling by thieves. A specific leakage detection often is used in order to limit the risks. The minimization of the consequences of accidents, downtimes and product losses as well as regulatory procedures is the reason for the detection of leakages. Leaks in pipelines can be detected on different kinds - from a simple visual inspection during the inspection up to computer-assisted systems monitoring certain states also in underground and submarine pipeline.

EDF operates 6 km of safety-classified steel cylinder reinforced concrete pipelines spread over 8 PWR nuclear reactors located on the sea coast. These pipelines, placed in galleries, convey approximately 3000 m 3 /h of sea water under a pressure of 4 bar. They have been in operation since the mid eighties or early nineties. Their service life is limited by different scenarios of corrosion by pitting due to the presence of chlorides from sea water. Pipelines are subjected to frequent visual checks that can lead to immediate temporary reinforcement and subsequent replacement. In addition, a diagnosis methodology was developed in order to better anticipate the maintenance operations and in order to assess the remaining service life of pipelines. This methodology combines autopsies of replaced pipes with periodic campaigns of exhaustive half-cell potential mapping. For exhaustive campaigns, the grid spacing was 30 cm x 30 cm, refined to 10 cm x 10 cm in singular zones, on the entire external concrete surface of pipelines, which represents around 6x10 5 measurement points for 6 km of pipelines. Robust specifications were drawn up for the measurement method and the interpretation of the results, initially based on RILEM and ASTM recommendations and then significantly reinforced based on operational feedback. These specifications ensure the implementation and the interpretation of half-cell potential mapping can be carried out on a very large scale and enable the comparison of results between successive campaigns. The diagnosis methodology was a decisive factor in the planning of a preventive maintenance strategy which would enable a pipeline service life of 60 years. (authors)

Safety distance between underground natural gas and water pipeline facilities
International Nuclear Information System (INIS)
Mohsin, R.; Majid, Z.A.; Yusof, M.Z.
2014-01-01
A leaking water pipe bursting high pressure water jet in the soil will create slurry erosion which will eventually erode the adjacent natural gas pipe, thus causing its failure. The standard 300 mm safety distance used to place natural gas pipe away from water pipeline facilities needs to be reviewed to consider accidental damage and provide safety cushion to the natural gas pipe. This paper presents a study on underground natural gas pipeline safety distance via experimental and numerical approaches. The pressure–distance characteristic curve obtained from this experimental study showed that the pressure was inversely proportional to the square of the separation distance. Experimental testing using water-to-water pipeline system environment was used to represent the worst case environment, and could be used as a guide to estimate appropriate safety distance. Dynamic pressures obtained from the experimental measurement and simulation prediction mutually agreed along the high-pressure water jetting path. From the experimental and simulation exercises, zero effect distance for water-to-water medium was obtained at an estimated horizontal distance at a minimum of 1500 mm, while for the water-to-sand medium, the distance was estimated at a minimum of 1200 mm. - Highlights: • Safe separation distance of underground natural gas pipes was determined. • Pressure curve is inversely proportional to separation distance. • Water-to-water system represents the worst case environment. • Measured dynamic pressures mutually agreed with simulation results. • Safe separation distance of more than 1200 mm should be applied

Bacteria rarely produce natural 2-phenylethanol. We verified a new pathway from Proteus mirabilis JN458 to produce 2-phenylethanol using Escherichia coli to coexpress l-amino acid deaminase, α-keto acid decarboxylase, and alcohol dehydrogenase from P. mirabilis. Based on this pathway, a glucose dehydrogenase coenzyme regeneration system was constructed. The optimal conditions of biotransformation by the recombinant strain E-pAEAKaG were at 40 °C and pH 7.0. Finally, the recombinant strain E-pAEAKaG produced 3.21 ± 0.10 g/L 2-phenylethanol in M9 medium containing 10 g/L l-phenylalanine after a 16 h transformation. Furthermore, when the concentration of l-phenylalanine was 4 g/L (24 mM), the production of 2-phenylethanol reached 2.88 ± 0.18 g/L and displayed a higher conversion rate of 97.38 mol %.

Full Text Available Medical gases are nowadays being used for a number of diverse clinical applications and its piped delivery is a landmark achievement in the field of patient care. Patient safety is of paramount importance in the design, installation, commissioning, and operation of medical gas pipeline systems (MGPS. The system has to be operational round the clock, with practically zero downtime and its failure can be fatal if not restored at the earliest. There is a lack of awareness among the clinicians regarding the medico-legal aspect involved with the MGPS. It is a highly technical field; hence, an in-depth knowledge is a must to ensure safety with the system.

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 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.

Tunneling excavation is bound to produce significant disturbances to surrounding environments, and the tunnel-induced damage to adjacent underground buried pipelines is of considerable importance for geotechnical practice. A fuzzy Bayesian networks (FBNs) based approach for safety risk analysis is developed in this article with detailed step-by-step procedures, consisting of risk mechanism analysis, the FBN model establishment, fuzzification, FBN-based inference, defuzzification, and decision making. In accordance with the failure mechanism analysis, a tunnel-induced pipeline damage model is proposed to reveal the cause-effect relationships between the pipeline damage and its influential variables. In terms of the fuzzification process, an expert confidence indicator is proposed to reveal the reliability of the data when determining the fuzzy probability of occurrence of basic events, with both the judgment ability level and the subjectivity reliability level taken into account. By means of the fuzzy Bayesian inference, the approach proposed in this article is capable of calculating the probability distribution of potential safety risks and identifying the most likely potential causes of accidents under both prior knowledge and given evidence circumstances. A case concerning the safety analysis of underground buried pipelines adjacent to the construction of the Wuhan Yangtze River Tunnel is presented. The results demonstrate the feasibility of the proposed FBN approach and its application potential. The proposed approach can be used as a decision tool to provide support for safety assurance and management in tunnel construction, and thus increase the likelihood of a successful project in a complex project environment. © 2015 Society for Risk Analysis.

2005-07-01
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)

Full Text Available A valuable strategy to improve crop yield consists in the use of plant growth-promoting rhizobacteria (PGPRs. However, the influence of PGPR colonization on plant physiology is largely unknown. PGPR Burkholderia phytofirmans strain PsJN (Bp PsJN colonized only Arabidopsis thaliana roots after seed or soil inoculation. Foliar bacteria were detected only after leaf infiltration. Since different bacterial times of presence and/or locations in host plant could lead to different plant physiological responses, photosynthesis and metabolite profiles in A. thaliana leaves were thus investigated following leaf, root or seed inoculation with Bp PsJN. Only Bp PsJN leaf colonization transiently decreased cyclic electron transport and effective quantum yield of photosystem I (PSI, and prevented a decrease in net photosynthesis and stomatal opening compared to the corresponding control. Metabolomic analysis revealed that soluble sugars, amino acids or their derivatives accumulated differently in all Bp PsJN-inoculated plants. Octanoic acid accumulated only in case of inoculated plants. Modifications in vitamin, organic acid such as tricarboxylic acid intermediates, and hormone amounts were dependent on bacterial time of presence and location. Additionally, a larger array of amino acids and hormones (auxin, cytokinin, abscisic acid were modified by seed inoculation with Bp PsJN. Our work thereby provides evidence that relative short-term inoculation with Bp PsJN altered physiological status of A.thaliana leaves, whereas long-term bacterization triggered modifications on a larger set of metabolites. Our data highlighted the changes displayed during this plant-microbe interaction to trigger physiological and metabolic responses that could explain the increase in plant growth or stress tolerance conferred by the presence of Bp PsJN.

Highlights: • A real-time leak detection method is developed for ammonia pipeline in cold storage. • A locating algorithm based on pressure difference profile is provided. • This method is validated by R22 and ammonia leak experiments. • The minimum detectable leak ratio is 1% for R22 and 4% for ammonia. • The location estimating errors are −27% ~ 17% for R22 and −27% ~ 27% for ammonia. - Graphical Abstract: - Abstract: Leakage from pressurized liquid ammonia pipeline has been a serious problem in large commercial cold storages because it might release large amount of liquid ammonia and without safety supervision in daily operations. The present paper shows a detection method for a pressurized liquid ammonia pipeline with a leak. The variations of pressure, flow rate and pressure difference profile are studied. A leak indicator (σ), proposed with the one-dimensional steady-state flow model, is used to detect the leak occurrence by comparing it with a threshold value (σ Le ). A locating algorithm based on pressure difference profile along the pipeline is also proposed, which has considered the effect of the static pressure increase at the leak point. Experiments on different leak positions and ratios from liquid R22 and ammonia pipelines are carried out to validate this method. It is found that, with a relatively low false alarm rate (as three percent), the minimum detectable leak ratio reached 1% for the R22 pipeline and 4% for the ammonia pipeline. The locating errors are between −27% ~ 17% for R22 pipeline and −27% ~ 27% for ammonia pipeline.

Pipeline corrosion prevention by pH stabilization or corrosion inhibitors
Energy Technology Data Exchange (ETDEWEB)
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)

Full Text Available Several plant growth-promoting rhizobacteria (PGPR are known to improve plant tolerance to multiple stresses, including low temperatures. However, mechanisms underlying this protection are still poorly understood. The aim of this study was to evaluate the role of the endophytic PGPR, Burkholderia phytofirmans strain PsJN (Bp PsJN, on Arabidopsis thaliana cold tolerance using photosynthesis parameters as physiological markers.Under standard conditions, our results indicated that Bp PsJN inoculation led to growth promotion of Arabidopsis plants without significant modification on photosynthesis parameters and chloroplast organization. However, bacterial colonization induced a cell wall strengthening in the mesophyllImpact of inoculation modes (either on seeds or by soil irrigation and their effects overnight at 0, -1 or -3°C, were investigated by following photosystem II (PSII activity and gas exchanges. Following low temperatures stress, a decrease of photosynthesis parameters was observed. In addition, during three consecutive nights or days at -1°C, PSII activity was monitored. Pigment contents, RuBisCO protein abundance, expression of several genes including RbcS, RbcL, CBF1, CBF2, CBF3, ICE1, COR15a, and COR78 were evaluated at the end of exposure. To assess the impact of the bacteria on cell ultrastructure under low temperatures, microscopic observations were achieved. Results indicated that freezing treatment induced significant changes in PSII activity as early as the first cold day, whereas the same impact on PSII activity was observed only during the third cold night. The significant effects conferred by PsJN were differential accumulation of pigments, and reduced expression of RbcL and COR78. Microscopical observations showed an alteration/disorganization in A. thaliana leaf mesophyll cells independently of the freezing treatments. The presence of bacteria during the three successive nights or days did not significantly improved A

The water crossing is part of the 32 km South Okanagan Natural Gas Pipeline Project (SONG) operated by BC Gas. The pipeline is located in a region dependent on year-round tourism. Therefore, the design and construction was influenced by sensitive environmental and land use concerns. From earlier studies, BC Gas identified surface tow or lay as preferred installation methods. The contractor, Fraser River Pile and Dredge departed from a conventional laybarge methodology after evaluating environmental data and assessing locally available equipment. The contractor proposed a surface tow with multiple surface tie-ins. This approach modification to the ''Surface Tow and Buoy Release Method'' (STBRM) used previously with success on relatively short underwater pipelines. A total of 10 pipe strings, up to 1 km long, were towed into position on the lake and tied-in using a floating platform. The joined pipeline was lowered to the lakebed by divers releasing buoys while tension was maintained from a winch barge at the free end of the pipeline. From analysis and field verified measurement the installation stresses were well below the allowable limits during all phases of construction. The entire construction, including mobilization and demobilization, lasted less than three months, and actual pipelaying less than three weeks. Installation was completed within budget and on schedule, without any environmental or safety related incidents. The SONG pipeline became operational in December 1994

The low-temperature properties of a diluted antiferromagnetic pyrochlore slab of S = 3/2 spins are investigated through a study of the frustrated oxides Ba 2 Sn 2 Ga 10-7p ZnCr 7p O 22 (p>0.85). Powder neutron diffraction and 119 Sn Moessbauer absorption show no evidence of long-range magnetic order above 1.5 K. As in SrCr 9q Ga 12-9q O 19 , diffuse magnetic scattering, indicative of short range spin-spin correlations, is observed at low temperature. The dependence of the low-temperature sub-Curie bulk susceptibility to weak site depletion is the inverse of that observed in SrCr 9q Ga 12-9q O 19

Statistical analyses of incidents on onshore gas transmission pipelines based on PHMSA database
International Nuclear Information System (INIS)
Lam, Chio; Zhou, Wenxing
2016-01-01
This article reports statistical analyses of the mileage and pipe-related incidents data corresponding to the onshore gas transmission pipelines in the US between 2002 and 2013 collected by the Pipeline Hazardous Material Safety Administration of the US Department of Transportation. The analysis indicates that there are approximately 480,000 km of gas transmission pipelines in the US, approximately 60% of them more than 45 years old as of 2013. Eighty percent of the pipelines are Class 1 pipelines, and about 20% of the pipelines are Classes 2 and 3 pipelines. It is found that the third-party excavation, external corrosion, material failure and internal corrosion are the four leading failure causes, responsible for more than 75% of the total incidents. The 12-year average rate of rupture equals 3.1 × 10"−"5 per km-year due to all failure causes combined. External corrosion is the leading cause for ruptures: the 12-year average rupture rate due to external corrosion equals 1.0 × 10"−"5 per km-year and is twice the rupture rate due to the third-party excavation or material failure. The study provides insights into the current state of gas transmission pipelines in the US and baseline failure statistics for the quantitative risk assessments of such pipelines. - Highlights: • Analyze PHMSA pipeline mileage and incident data between 2002 and 2013. • Focus on gas transmission pipelines. • Leading causes for pipeline failures are identified. • Provide baseline failure statistics for risk assessments of gas transmission pipelines.

To present prenatal diagnosis and molecular cytogenetic characterization of Wolf-Hirschhorn syndrome (WHS) associated with microduplications at 8p and 10p in a fetus with an apparently pure 4p deletion. A 35-year-old gravida 2, para 1 woman underwent amniocentesis at 18 weeks of gestation because of advanced maternal age. Her husband was 38 years of age. There was no family history of congenital malformations. Amniocentesis revealed a karyotype of 46,XY,del(4p16.1). The parental karyotypes were normal. Array comparative genomic hybridization (aCGH) analysis revealed a 6.5-Mb deletion at 4p16.3-p16.1, a 1.2-Mb microduplication at 8p22-p21.3, and a 1.1-Mb microduplication at 10p15.3, or arr cgh 4p16.3p16.1 (0-6,531,998 bp)×1, 8p22p21.3 (18,705,388-19,940,445 bp)×3, 10p15.3 (0-1,105,065 bp)×3. Polymorphic DNA marker analysis confirmed a paternal origin of 4p deletion. Prenatal ultrasound revealed facial dysmorphism and hypospadias. The aCGH analysis of the parents revealed no genomic imbalance. Fluorescence in situ hybridization study showed an unbalanced reciprocal translocation between chromosomes 4 and 10 at bands 4p16.1 and 10p15.3. The cytogenetic result, thus, was 46,XY,der(4)t(4;10)(p16.1;p15.3),dup(8)(p21.3p22). The parents elected to terminate the pregnancy, and a 470-g malformed fetus was delivered. The present case provides evidence that an apparently pure 4p deletion can be associated with subtle chromosome imbalances in other chromosomes. Copyright © 2011. Published by Elsevier B.V.

NONE
2005-05-31
A revised Pipeline Regulation has been issued and is currently available on the Alberta Energy and Utilities Board (EUB) website. Changes to the regulation reflect bothchanges in EUB regulatory policy and processes and technological improvements. Goals of the revision include improvements in overall pipeline performance, and the implementation of recommendations derived from the Public Safety and Sour Gas Committee concerning sour gas pipeline safety. The regulation was re-organized for greater clarity, and structured into 11 parts. Issues concerning the transition to the revised regulation were presented. The summary of notable administrative changes included clarifications of when a pipeline application is not required; when ABSA approval is required for steam lines; situations for which low-pressure natural gas lines must be licensed; and emergency response requirements. Technical clarifications include requirements for pipeline operations and maintenance manuals; composite materials; limitations on amounts of H{sub 2}S in polymeric pipe; pressure mismatches; approval for testing with gaseous media; venting of small volumes of raw gas; right-of-way surveillance; inspection of surface construction activities; annual corrosion evaluations; registering of pipelines and excavators in controlled areas with Alberta One-Call; ground disturbance training; restoration and signage maintenance on abandoned pipelines; sour service steel pipelines; unused pipelines and abandoned pipelines; and remediation of stub ends in operating pipelines.

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.

The flow of cold helium in pipes is a fundamental issue of any cryogenic installation. Pipelines for helium transportation can reach lengths of hundreds of meters. The proper selection of size for individual pipelines and safety valves is a crucial part in the consideration of costs for the entire installation and its safe operation. The size of the safety valve must be properly designed in order to avoid a dangerous pressure buildup during normal operation, as well as in the case of emergency. The most commonly occurring dangerous situation is an undesired heat flux in the helium as a result of a broken insulation. In this case, the heat flux can be very intense and the buildup of the pressure in the pipe can be very rapid. In the present work, numerical calculations were used to evaluate the buildup of pressure and temperature in the pipe, in the case of a sudden and intense heat flux. The main goal of the applied numerical procedure was to evaluate the proper sizes of the safety valves in order to avoid a...

Natural gas is the largest source of anthropogenic emissions of methane (CH 4 ) in the United States. To assess pipeline emissions across a major city, we mapped CH 4 leaks across all 785 road miles in the city of Boston using a cavity-ring-down mobile CH 4 analyzer. We identified 3356 CH 4 leaks with concentrations exceeding up to 15 times the global background level. Separately, we measured δ 13 CH 4 isotopic signatures from a subset of these leaks. The δ 13 CH 4 signatures (mean = −42.8‰ ± 1.3‰ s.e.; n = 32) strongly indicate a fossil fuel source rather than a biogenic source for most of the leaks; natural gas sampled across the city had average δ 13 CH 4 values of −36.8‰ (±0.7‰ s.e., n = 10), whereas CH 4 collected from landfill sites, wetlands, and sewer systems had δ 13 CH 4 signatures ∼20‰ lighter (μ = −57.8‰, ±1.6‰ s.e., n = 8). Repairing leaky natural gas distribution systems will reduce greenhouse gas emissions, increase consumer health and safety, and save money. Highlights: ► We mapped 3356 methane leaks in Boston. ► Methane leaks in Boston carry an isotopic signature of pipeline natural gas. ► Replacing failing gas pipelines will provide safety, environmental, and economic benefits. - We identified 3356 methane leaks in Boston, with isotopic characteristics consistent with pipeline natural gas.

This paper discussed a chilled pipeline frost-heave testing facility that was developed to simulate and record the rate of frost heave and frost-bulb growth for a buried, chilled pipeline in frost-susceptible soil and to determine the effectiveness of different mitigation techniques. The test facility, which was established near Fairbanks, Alaska, in 1979, has 10 test sections using 1.22-metre-diameter pipe. The testing involved un-insulated, insulated, and insulated with over-excavation and gravel berm configurations as well as the frost heave of the chilled pipeline. The test facility was described in detail. Frost heave and frost-bulb growth measurements from the first 10 months of testing were presented, as these are the first data to enter the public domain. The testing was undertaken to investigate the frost-heave relationships between sections, to better understand frost heave in permafrost, to explore possible mitigation options, and to advance the predicative capabilities of frost heave models. 12 refs., 1 tab., 17 figs.

The capacity of Trichoderma reesei cellulase to degrade lignocellulosic biomass has been enhanced by the construction of a recombinant T. reesei strain expressing Aspergillus aculeatus β-glucosidase I. We have confirmed highly efficient ethanol production from converge-milled Japanese cedar by recombinant T. reesei expressing A. aculeatus β-glucosidase I (JN11). We investigated the ethanol productivity of JN11 and compared it with the cocktail enzyme T. reesei PC-3-7 with reinforced cellobiase activity by the commercial Novozyme 188. Results showed that the ethanol production efficiency under enzymatic hydrolysis of JN11 was comparable to the cocktail enzyme both on simultaneous saccharification and fermentation (SSF) or separate hydrolysis and fermentation (SHF) processes. Moreover, the cocktail enzyme required more protein loading for attaining similar levels of ethanol conversion as JN11. We propose that JN11 is an intrinsically economical enzyme that can eliminate the supplementation of BGL for PC-3-7, thereby reducing the cost of industrial ethanol production from lignocellulosic biomass.

Sub sea hot tapping of pipelines is performed for a variety of reasons, including tie-ins, pipeline repair, insertion of instrumentation, facilitating chemical injection or providing access for temporary isolation tools. The full hot tap process - that is, installing the hot tap assembly, performing the tap and recovering the hot tap machine - is normally conducted with diver assistance. After bolting the assembly of the machine, isolation valve and fitting to the pipeline (or machine and isolation valve to a pre-installed flanged membrane on the pipeline), the divers then operate the machine to perform the tap, under instructions from - and supervision by - hot tap technicians located on deck of the diving support vessel (DSV). Subsequent unbolting and removal of the hot tap machine is also carried out by the divers. The demands of deep water have necessitated development of a totally diver-less, remote-controlled system. Diver operations are limited to a maximum of 300 meters of water depth, whereas a significant portion of existing sub sea field infrastructure, as well as projected future developments, are in deeper waters in depths up to 3,000 meters. In addition, diver safety concerns in shallow water, as well as impaired diver efficiency in difficult environmental conditions such as wave breaking zones, prompts the call for a reduction of diver exposure or complete elimination of diver assistance. The recent completion of a remote-controlled hot tap machine (the Sub sea 1200RC Tapping Machine) is a first step toward developing a totally diver-less system. The installation of the hot tap assembly and subsequent removal of the machine still require diver assistance, but the performance of the tap itself is remotely controlled by a hot tap technician from the deck of the DSV. The concept is a topside-driven hot tap machine with 'passive Remote Operating Vehicle (ROV) interface', which means a stationary ROV with its hydraulics and control system

Thermal expansion absorbing structure for pipeline
International Nuclear Information System (INIS)
Nagata, Takashi; Yamashita, Takuya.
1995-01-01
A thermal expansion absorbing structure for a pipeline is disposed to the end of pipelines to form a U-shaped cross section connecting a semi-circular torus shell and a short double-walled cylindrical tube. The U-shaped longitudinal cross-section is deformed in accordance with the shrinking deformation of the pipeline and absorbs thermal expansion. Namely, since the central lines of the outer and inner tubes of the double-walled cylindrical tube deform so as to incline, when the pipeline is deformed by thermal expansion, thermal expansion can be absorbed by a simple configuration thereby enabling to contribute to ensure the safety. Then, the entire length of the pipeline can greatly be shortened by applying it to the pipeline disposed in a high temperature state compared with a method of laying around a pipeline using only elbows, which has been conducted so far. Especially, when it is applied to a pipeline for an FBR-type reactor, the cost for the construction of a facility of a primary systems can greater be reduced. In addition, it can be applied to a pipeline for usual chemical plants and any other structures requiring absorption of deformation. (N.H.)

However, until recently, schizophrenia GWASs in non-European populations were limited to small sample sizes and have yielded few loci associated with schizophrenia. To identify genetic risk variations for schizophrenia in the Han Chinese population, we performed a two-stage GWAS of schizophrenia comprising 4384 cases and 5770 controls, followed by independent replications of 13 single-nucleotide polymorphisms in an additional 4339 schizophrenia cases and 7043 controls of Han Chinese ancestry. Furthermore, we conducted additional analyses based on the results in the discovery stage. The combined analysis confirmed evidence of genome-wide significant associations in the Han Chinese population for three loci, at 2p16.1 (rs1051061, in an exon of VRK2, P=1.14 × 10 -12 , odds ratio (OR)=1.17), 6p22.1 (rs115070292 in an intron of GABBR1, P=4.96 × 10 -10 , OR=0.77) and 10q24.32 (rs10883795 in an intron of AS3MT, P=7.94 × 10 -10 , OR=0.87; rs10883765 at an intron of ARL3, P=3.06 × 10 -9 , OR=0.87). The polygenic risk score based on Psychiatric Genomics Consortium schizophrenia GWAS data modestly predicted case-control status in the Chinese population (Nagelkerke R 2 : 1.7% ~5.7%). Our pathway analysis suggested that neurological biological pathways such as GABAergic signaling, dopaminergic signaling, cell adhesion molecules and myelination pathways are involved in schizophrenia. These findings provide new insights into the pathogenesis of schizophrenia in the Han Chinese population. Further studies are needed to establish the biological context and potential clinical utility of these findings.

Pipeline integrity evaluation of oil pipelines using free-swimming acoustic technology
Energy Technology Data Exchange (ETDEWEB)
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.

By the year 2030 Europe's gas imports will have risen to approximately 200 bn m{sup 3}, necessitating the installation of new pipelines and LNG terminals. The largest growth in imports is not expected from Russia but from Africa and the Near East. An analysis of projected pipelines demonstrates these regions' contribution to securing Europe's gas supply. Because they help to establish market dominance or to fend off potential competitors these pipelines also serve corporate strategies. The most reliable supply will continue to come from Norway. By contrast, gas imports via pipelines from North Africa, Russia and the Persian Gulf all carry high risks of approximately the same degree. The greatest risks are associated with gas imports from the Caspian Sea.

Full Text Available The use of 0.8 design factor in Chinese pipeline industry is a breakthrough with the success of the test pipe section in the west–east China gas pipeline III. For such a design factor, the traditional P-V (Pressure-Volume curve based pressure test control cannot describe the details of the process, and the 0/1 type failure is not an efficient index to show the safety level of the pipeline. In this paper, a reliability based assessment method is proposed to monitor the real-time failure probability of the pipeline during the hydrostatic test process. The reliability index can be used as the degree of risk. Following the actual hydrostatic testing of a test pipe section with 0.8 design factor in the west–east China gas pipeline III, reliability analysis was performed using Monte Carlo technique. The basic values of input parameters of the limit state equations are based on the data collected from either the tested section or the recommended value in the codes. The analysis of limit states, i.e., the yielding deformation and the excessive plastic deformation of pipeline, proceeded based on these distributions. Finally, it is found that the gradually increased water pressure makes the failure probability increase accordingly. A reliability assessment method was proposed and illustrated with the practical pressure test process.

Full Text Available Constructive, technical and technological reliability of major pipeline ensures ecological safety on different stages of life circle - beginning with project preparation activities up to the end of major pipeline operation. Even in the process of transition into new life circle stage, no matter if the pipeline needs major repairs or reconstruction, such technical and technological solutions should be found, which would preserve ecological stability of nature-anthropogenic system. Development of ecology protection technologies of construction, reconstruction and major repairs of main pipelines is of great importance not only for a region, but ensures ecological safety across the globe. The article presents a new way of trenching the main oil and gas pipeline, preservation and increase of ecological safety during its service. The updated technological plan is given in the paper for overhaul of the main oil and gas pipeline using the new technology of pipeline trenching. The suggested technical solution contributes to environment preservation with the help of deteriorating shells - the shells’ material decomposes into environment-friendly components: carbon dioxide, water and humus. The quantity of polluting agents in the atmosphere decreases with the decrease of construction term and quantity of technical equipment.

Isolated 7p22.3p22.2 deletions are rarely described with only two reports in the literature. Most other reported cases either involve a much larger region of the 7p arm or have an additional copy number variation. Here, we report five patients with overlapping microdeletions at 7p22.3p22.2. The patients presented with variable developmental delays, exhibiting relative weaknesses in expressive language skills and relative strengths in gross, and fine motor skills. The most consistent facial features seen in these patients included a broad nasal root, a prominent forehead a prominent glabella and arched eyebrows. Additional variable features amongst the patients included microcephaly, metopic ridging or craniosynostosis, cleft palate, cardiac defects, and mild hypotonia. Although the patients' deletions varied in size, there was a 0.47 Mb region of overlap which contained 7 OMIM genes: EIP3B, CHST12, LFNG, BRAT1, TTYH3, AMZ1, and GNA12. We propose that monosomy of this region represents a novel microdeletion syndrome. We recommend that individuals with 7p22.3p22.2 deletions should receive a developmental assessment and a thorough cardiac exam, with consideration of an echocardiogram, as part of their initial evaluation. © 2017 Wiley Periodicals, Inc.

This paper presents the experience acquired by PETROBRAS Transporte S.A., TRANSPETRO, signaling the crossing of Sao Paulo - Brasilia Pipeline, OSBRA, with the Grande River, important brazilian river that has in this cross section 400 m in width and 10 m of average depth. In sub aquatic inspections carried through by divers to confirm the pipeline's silting condition, evidences of basin format dredging near the pipeline have been identified and, even though it was not sufficient to expose de pipeline, has reduced its covering significantly. This site is an important area of sand extraction, and although the intense works of awareness of local dredging companies to not operate in the pipeline area, TRANSPETRO was surprised by the evidences. In testimonials, local dredge operators complained about difficulties in identifying the pipeline position in nightly operations. Expecting to improve the operational security in the pipeline crossing, a joint project was developed by TRANSPETRO, Brazilian Navy and the dredging companies, with the intention to signal safe area around the submerged pipeline, avoiding dredge operations with the installation of polyethylene floating buoys equipped with night signaling kits and fixed by concrete anchors. Although it was technically simple, the unprecedented proposal in Brazil increased safety in the pipeline operations and made them much safer for the local population and for the environment, in one of the biggest water resources of the Southeastern region of Brazil.

This study assesses the effectiveness of block valve closure swiftness in mitigating the consequences of natural gas and hazardous liquid pipeline releases on public and environmental safety. It also evaluates the technical, operational, and economic feasibility and potential cost benefits of installing automatic shutoff valves (ASVs) and remote control valves (RCVs) in newly constructed and fully replaced transmission lines. Risk analyses of hypothetical pipeline release scenarios are used as the basis for assessing: (1) fire damage to buildings and property in Class 1, Class 2, Class 3, and Class 4 high consequence areas (HCAs) caused by natural gas pipeline releases and subsequent ignition of the released natural gas; (2) fire damage to buildings and property in HCAs designated as high population areas and other populated areas caused by hazardous liquid pipeline releases and subsequent ignition of the released propane; and (3) socioeconomic and environmental damage in HCAs caused by hazardous liquid pipeline releases of crude oil. These risk analyses use engineering principles and fire science practices to characterize thermal radiation effects on buildings and humans and to quantify the total damage cost of socioeconomic and environmental impacts. The risk analysis approach used for natural gas pipelines is consistent with risk assessment standards developed by industry and incorporated into Federal pipeline safety regulations. Feasibility evaluations for the hypothetical pipeline release scenarios considered in this study show that installation of ASVs and RCVs in newly constructed and fully replaced natural gas and hazardous liquid pipelines is technically, operationally, and economically feasible with a positive cost benefit. However, these results may not apply to all newly constructed and fully replaced pipelines because site-specific parameters that influence risk analyses and feasibility evaluations often vary significantly from one pipeline segment to

Research into the transmission of natural gas by gas pipeline
Energy Technology Data Exchange (ETDEWEB)
Gadonneix, P.
1998-12-31
This paper is the press release of the talk given at the `Gaz de France scientific meeting with the press` by P. Gadonneix, chairman of Gaz de France company, on October 7, 1998. The aim of this talk concerns the new French and European supply link for bringing natural gas from the Norwegian North Sea fields. This new supply link is the first direct link between Norway and France and the NorFra gas pipeline which brings natural gas from the North Sea to France is the longest offshore pipeline in the world. The `Artere des Hauts de France` pipeline (the largest diameter gas pipeline ever laid in France) is devoted to the transfer of natural gas from Dunkerque to the Gournay-sur-Aronde underground storage site. This paper describes successively: the French European gas supply hub, the NorFra project, the Artere des Hauts de France pipeline, the network performance research, the safety and quality guaranties, the reduction of overland natural gas transmission costs (improvement of pipe-laying techniques and optimization of line route and welding operations), the specific techniques used for road and river crossing (micro-tunnel digging, river-crossing ditches) and for anchoring (buoyancy compensation). Finally, the environmental impact of the laying operations is briefly described. (J.S.)

The Sloka pipeline branch was constructed in 1966-67. Between 1976 and 1985 a number of leaks were detected. The majority of leaks, from chainage appr. 22 km to appr. 29 km, were reported to be caused by stray current induced corrosion. Latvijas Gaze has expressed specific concern as to whether more corrosion defects, though not yet detected, may cause potential risks for future leaks. It was hence agreed at the project meeting in Riga on October 19, 1995, that Balslev should conduct an intensive potential and gradient survey covering appr. 10 km of pipeline up to the Sloka end. The branch is appr. 30,5 km long, and runs from a T-branch on the main pipeline Riga - Lipeija (chainage 0 km) to Sloka (chainage 30,5 km). The diameter of the pipeline is 273 mm and the thickness of the steel is 8 mm. The pipeline is running parallel to a DC-electrified railway over the last appr. 3 km. The stray current from the railway collected on the pipeline has been returned to the railway via two diode drain points. Today only one drain point is active. Stray current (or even reverse current) may be the reason for the serious corrosion defects, cf. Corrosion Report 1985 from `the Leningrade Institute`. (JT)

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.

Solving an unpiggable pipeline challenge

Walker, James R. [GE Oil and Gas, PII Pipeline Solutions, Cramlington Northumberland (United Kingdom); Kern, Michael [National Grid, New Hampshire (United Kingdom)
2009-07-01
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.

Natural gas pipeline leaks across Washington, DC.
Jackson, Robert B; Down, Adrian; Phillips, Nathan G; Ackley, Robert C; Cook, Charles W; Plata, Desiree L; Zhao, Kaiguang
2014-01-01
Pipeline safety in the United States has increased in recent decades, but incidents involving natural gas pipelines still cause an average of 17 fatalities and $133 M in property damage annually. Natural gas leaks are also the largest anthropogenic source of the greenhouse gas methane (CH4) in the U.S. To reduce pipeline leakage and increase consumer safety, we deployed a Picarro G2301 Cavity Ring-Down Spectrometer in a car, mapping 5893 natural gas leaks (2.5 to 88.6 ppm CH4) across 1500 road miles of Washington, DC. The δ(13)C-isotopic signatures of the methane (-38.2‰ ± 3.9‰ s.d.) and ethane (-36.5 ± 1.1 s.d.) and the CH4:C2H6 ratios (25.5 ± 8.9 s.d.) closely matched the pipeline gas (-39.0‰ and -36.2‰ for methane and ethane; 19.0 for CH4/C2H6). Emissions from four street leaks ranged from 9200 to 38,200 L CH4 day(-1) each, comparable to natural gas used by 1.7 to 7.0 homes, respectively. At 19 tested locations, 12 potentially explosive (Grade 1) methane concentrations of 50,000 to 500,000 ppm were detected in manholes. Financial incentives and targeted programs among companies, public utility commissions, and scientists to reduce leaks and replace old cast-iron pipes will improve consumer safety and air quality, save money, and lower greenhouse gas emissions.

Full Text Available Modulation of phytohormones homeostasis is one of the proposed mechanisms to explain plant growth promotion induced by beneficial rhizobacteria (PGPR. However, there is still limited knowledge about the molecular signals and pathways underlying these beneficial interactions. Even less is known concerning the interplay between phytohormones in plants inoculated with PGPR. Auxin and ethylene are crucial hormones in the control of plant growth and development, and recent studies report an important and complex crosstalk between them in the regulation of different plant developmental processes. The objective of this work was to study the role of both hormones in the growth promotion of Arabidopsis thaliana plants induced by the well-known PGPR Burkholderia phytofirmans PsJN. For this, the spatiotemporal expression patterns of several genes related to auxin biosynthesis, perception and response and ethylene biosynthesis were studied, finding that most of these genes showed specific transcriptional regulations after inoculation in roots and shoots. PsJN-growth promotion was not observed in Arabidopsis mutants with an impaired ethylene (ein2-1 or auxin (axr1-5 signaling. Even, PsJN did not promote growth in an ethylene overproducer (eto2, indicating that a fine regulation of both hormones signaling and homeostasis is necessary to induce growth of the aerial and root tissues. Auxin polar transport is also involved in growth promotion, since PsJN did not promote primary root growth in the pin2 mutant or under chemical inhibition of transport in wild type plants. Finally, a key role for ethylene biosynthesis was found in the PsJN-mediated increase in root hair number. These results not only give new insights of PGPR regulation of plant growth but also are also useful to understand key aspects of Arabidopsis growth control.

Full Text Available Plant growth-promoting rhizobacteria (PGPR induce positive effects in plants, such as increased growth or reduced stress susceptibility. The mechanisms behind PGPR/plant interaction are poorly understood, as most studies have described short-term responses on plants and only a few studies have analyzed plant molecular responses under PGPR colonization. Here, we studied the effects of the PGPR bacterial model Burkholderiaphytofirmans PsJN on the whole life cycle of Arabidopsis thaliana plants. We reported that at different plant developmental points, strain PsJN can be found in the rhizosphere and also colonizing their internal tissues. In early ontogeny, strain PsJN increased several growth parameters and accelerated growth rate of the plants. Also, an Arabidopsis transcriptome analysis revealed that 408 genes showed differential expression in PsJN-inoculated plants; some of these genes are involved in stress response and hormone pathways. Specifically, genes implicated in auxin and gibberellin pathways were induced. Quantitative transcriptional analyses of selected genes in different developmental stages revealed that the beginning of these changes could be evidenced early in development, especially among the down-regulated genes. The inoculation with heat-killed bacteria provoked a more severe transcriptional response in plants, but was not able to induce plant growth-promotion. Later in ontogeny, the growth rates of inoculated plants decreased with respect to the non-inoculated group and, interestingly, the inoculation accelerated the flowering time and the appearance of senescence signs in plants; these modifications correlate with the early up-regulation of flowering control genes. Then, we show that a single inoculation with a PGPR could affect the whole life cycle of a plant, accelerating its growth rate and shortening its vegetative period, both effects relevant for most crops. Thus, these findings provide novel and interesting aspects

A 10-bit 50-MS/s subsampling pipelined ADC based on SMDAC and opamp sharing
Energy Technology Data Exchange (ETDEWEB)
Chen Lijie; Zhou Yumei; Wei Baoyue, E-mail: frankdhz@yahoo.com.cn [Institute of Microelectronics, Chinese Academy of Sciences, Beijing 100029 (China)
2010-11-15
This paper describes a 10-bit, 50-MS/s pipelined A/D converter (ADC) with proposed area- and power-efficient architecture. The conventional dedicated sample-hold-amplifier (SHA) is eliminated and the matching requirement between the first multiplying digital-to-analog converter (MDAC) and sub-ADC is also avoided by using the SHA merged with the first MDAC (SMDAC) architecture, which features low power and stabilization. Further reduction of power and area is achieved by sharing an opamp between two successive pipelined stages, in which the effect of opamp offset and crosstalk between stages is decreased. So the 10-bit pipelined ADC is realized using just four opamps. The ADC demonstrates a maximum signal-to-noise distortion ratio and spurious free dynamic range of 52.67 dB and 59.44 dB, respectively, with a Nyquist input at full sampling rate. Constant dynamic performance for input frequencies up to 49.7 MHz, which is the twofold Nyquist rate, is achieved at 50 MS/s. The ADC prototype only occupies an active area of 1.81 mm{sup 2} in a 0.35 {mu}m CMOS process, and consumes 133 mW when sampling at 50 MHz from a 3.3-V power supply.

Italmontaggi builds expertise Conquering monsoons, adverse conditions Bangladesh pipelines
Energy Technology Data Exchange (ETDEWEB)
1984-10-01
Bangladesh natural gas pipeline projects have become a specialty for Italmontaggi Pte Ltd., Singapore-based gas pipeline contractor and engineering organization. The firm's latest project is a 35-mile, 24-in. gas pipeline, branching from the Bakhrabad-Chittagong main gas pipeline to the city gate station at Demra, near the capital city of Dacca. Gas is delivered to the Titas gas distribution system. The 35-mile turnkey project, valued at $25 million, included design, procurement, construction, and commissioning. A small pipeline was in existence from the Titas gas field to Dacca, but increased demand caused acute power shortages in the capital city's industrial areas. The new gas line will alleviate that problem. That project is a followup to Italmontaggi's successful completion of the major 108-mile, 24-in. main gas pipeline between the Bakhrabad gas fields, outside Dhaha, to the country's principal port and industrial center at Chittagong. Italmontaggi also installed 22 miles of ring main for the Chittagong gas distribution system. That included 12 miles of 24-in. and 10 miles of 16- and 20-in. to provide connections to industrial customers. Bangladesh lines difficult. The $45million contract for the Bakhrabad-toChittagong pipeline to Italmlontaggi, an autonomous offshoot of the Italian firm, resulted in a constant battle against hostile ground conditions, difficult access, and rapidly changing weather conditions. October-to- April is the dry season and Mayto-September is the wet season in this region. To keep the project moving, Italmontaggi developed two independent techniques for ground preparation during the wet season, and a pipelaying technique for the dry season. The new gas pipeline provides a major saving to the Bangladesh national economy as industries convert from oil to gas. Predicted savings are for more than $100 million in energy costs.

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)

This paper presents a 12-bit pipelined successive approximation register (SAR) ADC for CZT-based hard X-ray Imager. The proposed ADC is comprised of a first-stage 6-bit SAR-based Multiplying Digital Analog Converter (MDAC) and a second-stage 8-bit SAR ADC. A novel MDAC architecture using Vcm-based Switching method is employed to maximize the energy efficiency and improve the linearity of the ADC. Moreover, the unit-capacitor array instead of the binary-weighted capacitor array is adopted to improve the conversion speed and linearity of the ADC in the first-stage MDAC. In addition, a new layout design method for the binary-weighted capacitor array is proposed to reduce the capacitor mismatches and make the routing become easier and less-time-consuming. Finally, several radiation-hardened-by-design technologies are adopted in the layout design against space radiation effects. The prototype chip was fabricated in 0.18 μm mixed-signal 1.8V/3.3V process and operated at 1.8 V supply. The chip occupies a core area of only 0.58 mm2. The proposed pipelined SAR ADC achieves a peak signal-to-noise-and-distortion ratio (SNDR) of 66.7 dB and a peak spurious-free dynamic range (SFDR) of 78.6 dB at 10 MS/s sampling rate and consumes 10 mW. The figure of merit (FOM) of the proposed ADC is 0.56 pJ/conversion-step.

Northern pipelines : backgrounder
International Nuclear Information System (INIS)
2002-04-01
Most analysts agree that demand for natural gas in North America will continue to grow. Favourable market conditions created by rising demand and declining production have sparked renewed interest in northern natural gas development. The 2002 Annual Energy Outlook forecasted U.S. consumption to increase at an annual average rate of 2 per cent from 22.8 trillion cubic feet to 33.8 TCF by 2020, mostly due to rapid growth in demand for electric power generation. Natural gas prices are also expected to increase at an annual average rate of 1.6 per cent, reaching $3.26 per thousand cubic feet in 2020. There are currently 3 proposals for pipelines to move northern gas to US markets. They include a stand-alone Mackenzie Delta Project, the Alaska Highway Pipeline Project, and an offshore route that would combine Alaskan and Canadian gas in a pipeline across the floor of the Beaufort Sea. Current market conditions and demand suggest that the projects are not mutually exclusive, but complimentary. The factors that differentiate northern pipeline proposals are reserves, preparedness for market, costs, engineering, and environmental differences. Canada has affirmed its role to provide the regulatory and fiscal certainty needed by industry to make investment decisions. The Government of the Yukon does not believe that the Alaska Highway Project will shut in Mackenzie Delta gas, but will instead pave the way for development of a new northern natural gas industry. The Alaska Highway Pipeline Project will bring significant benefits for the Yukon, the Northwest Territories and the rest of Canada. Unresolved land claims are one of the challenges that has to be addressed for both Yukon and the Northwest Territories, as the proposed Alaska Highway Pipeline will travel through traditional territories of several Yukon first Nations. 1 tab., 4 figs

Alternate current interference in pipeline; Interferencia por corrente alternada em dutos
Energy Technology Data Exchange (ETDEWEB)
Oliver, Joao Hipolito de Lima [TRANSPETRO - PETROBRAS Transporte S.A., Rio de Janeiro, RJ (Brazil)
2003-07-01
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)

A comprehensive evaluation of the sl1p pipeline for 16S rRNA gene sequencing analysis.
Whelan, Fiona J; Surette, Michael G
2017-08-14
Advances in next-generation sequencing technologies have allowed for detailed, molecular-based studies of microbial communities such as the human gut, soil, and ocean waters. Sequencing of the 16S rRNA gene, specific to prokaryotes, using universal PCR primers has become a common approach to studying the composition of these microbiota. However, the bioinformatic processing of the resulting millions of DNA sequences can be challenging, and a standardized protocol would aid in reproducible analyses. The short-read library 16S rRNA gene sequencing pipeline (sl1p, pronounced "slip") was designed with the purpose of mitigating this lack of reproducibility by combining pre-existing tools into a computational pipeline. This pipeline automates the processing of raw 16S rRNA gene sequencing data to create human-readable tables, graphs, and figures to make the collected data more readily accessible. Data generated from mock communities were compared using eight OTU clustering algorithms, two taxon assignment approaches, and three 16S rRNA gene reference databases. While all of these algorithms and options are available to sl1p users, through testing with human-associated mock communities, AbundantOTU+, the RDP Classifier, and the Greengenes 2011 reference database were chosen as sl1p's defaults based on their ability to best represent the known input communities. sl1p promotes reproducible research by providing a comprehensive log file, and reduces the computational knowledge needed by the user to process next-generation sequencing data. sl1p is freely available at https://bitbucket.org/fwhelan/sl1p .

2003-07-01
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

Development of Protective Coatings for Co-Sequestration Processes and Pipelines
Energy Technology Data Exchange (ETDEWEB)
Bierwagen, Gordon; Huang, Yaping
2011-11-30
The program, entitled Development of Protective Coatings for Co-Sequestration Processes and Pipelines, examined the sensitivity of existing coating systems to supercritical carbon dioxide (SCCO2) exposure and developed new coating system to protect pipelines from their corrosion under SCCO2 exposure. A literature review was also conducted regarding pipeline corrosion sensors to monitor pipes used in handling co-sequestration fluids. Research was to ensure safety and reliability for a pipeline involving transport of SCCO2 from the power plant to the sequestration site to mitigate the greenhouse gas effect. Results showed that one commercial coating and one designed formulation can both be supplied as potential candidates for internal pipeline coating to transport SCCO2.

Coat proteins of tailed, dsDNA phages and in herpesviruses include a conserved core similar to the bacteriophage HK97 subunit. This core is often embellished with other domains such as the telokin Ig-like domain of phage P22. Eighty-six P22-like phages and prophages with sequenced genomes share a similar set of virion assembly genes and, based on comparisons of twelve viral assembly proteins (structural and assembly/packaging chaperones), these phages are classified into three groups (P22-like, Sf6-like, and CUS-3-like). We used cryo-electron microscopy and 3D image reconstruction to determine the structures of Sf6 procapsids and virions ({approx} 7 A resolution), and the structure of the entire, asymmetric Sf6 virion (16-A resolution). The Sf6 coat protein is similar to that of P22 yet it has differences in the telokin domain and in its overall quaternary organization. Thermal stability and agarose gel experiments show that Sf6 virions are slightly less stable than those of P22. Finally, bacterial host outer membrane proteins A and C were identified in lipid vesicles that co-purify with Sf6 particles, but are not components of the capsid.

2018-03-01
The paper outlines issues related to ensuring the exploitation safety of underwater pipelines that are at risk of accidents. The performed research is based on physical and mathematical modeling of local bottom erosion in the area of pipeline location. The experimental studies were performed on the basis of the Hydraulics Laboratory of the Department of Hydraulic Engineering Construction, Safety and Ecology of NSUACE (Sibstrin). In the course of physical experiments it was revealed that the intensity of the bottom soil reforming depends on the deepening of the pipeline. The ANSYS software has been used for numerical modeling. The process of erosion of the sandy bottom was modeled under the pipeline. Comparison of computational results at various mass flow rates was made.

This report discussed an oil spill which occurred in July 2007 when a contractor's excavator bucket punctured a pipeline during the excavation of a trench for a new storm sewer line at a location in Burnaby, British Columbia (BC). The puncture caused the release of approximately 234 cubic meters of crude oil, which flowed into Burrard Inlet Bay via a storm sewer system. Eleven houses were sprayed with crude oil, and many other properties required restoration. Approximately 250 residents left their homes. While emergency workers and firefighters responding to the incident were sprayed with crude oil, no explosions, fires, or injuries occurred. The report provided details of studies conducted to determine the placement of the sewer line, as well as attempts made by the contractors to determine the lateral connection of the crude oil pipeline. Discrepancies between the location of the pipeline design drawing and its actual location on other construction drawings were also noted by the contractor. Twenty-four minutes after the rupture, the terminal was fully isolated and the drain-down of the pipeline was completed within an hour. The cause of the accident was attributed to inaccurate construction drawings and inadequate communications between contractors and consulting companies. 3 figs

Virtual Instrumentation Corrosion Controller for Natural Gas Pipelines
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.

A contribution to the study of excited states of Neon 22 and Sodium 22
International Nuclear Information System (INIS)
Chambon, Bernard.
1976-01-01
The experimental study of 22 Ne has been performed. A differentially pump gas target has been used, in conjunction with E+ΔE detectors. Angular distribution measurements have been performed on the 21 Ne(d,p) 22 Ne reaction in the Esub(d) energy range from 3 to 3.6MeV. Angular momentum has been identified and spectroscopic factors extracted for 18 levels by comparison with DWBA predictions. Spin and parities of some excited levels were deduced. The study of the 21 Ne(t,d) 22 Ne reaction corroborates the results concerning the first excited state (2 + ). Experimental results are compared with the predictions of the unified rotational model and of the shell-model. The 20 Ne(t,p) 22 Ne reaction was studied at 3MeV and 3.4MeV bombarding energies. The total cross-section of most groups was analyzed in terms of Hauser-Feshbach theory and several final-state spin predictions are made. The angular distribution of the 20 Ne(t,p) 22 Ne (Esub(x)=6.24MeV) reaction was analyzed by double stripping DWBA theory and indicates 0 + for this state, the isobaric analog of which has been identified at 6.83MeV in 22 Na. Furthermore, several new isobaric analog pairs in 22 Na and 22 Ne are identified via the study of excitation functions for the reactions 21 Ne(p,p) 21 Ne and 21 Ne(p,p') 21 Ne for Esub(p)=0.6-2MeV. Implications of the present results with regard to the identification of band structure in 22 Na are discussed [fr

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.

PETROBRAS has made a huge effort to inspect and rehabilitate its pipeline net, mainly over the past 10 years. Currently, E and P inspection teams are being challenged to find feasible solutions for the inspection of non-piggable pipelines, so named because they have unsuitable geometry and/or operating conditions for usual in-line inspections. Inside this pipeline category, flow lines, injection and distribution lines and even non-metallic pipelines may be highlighted. This paper presents the results of tests and developments of new inspection tools for the inspection of non piggable pipelines, future tests to be performed in PETROBRAS/E and P Bahia (UN-BA) and some inspection cases in which the operating conditions hinder the run of smart pigs.

AlAhmari, Saad A. [Saudi Aramco, Dhahran (Saudi Arabia)
2009-12-19
Saudi Aramco pipelines network transports hydrocarbons to export terminals, processing plants and domestic users. This network faced several safety and operational-related challenges that require having a more effective Pipelines Integrity Management System (PIMS). Therefore Saudi Aramco decided to develop its PIMS on the basis of geographical information system (GIS) support through different phases, i.e., establishing the integrity management framework, risk calculation approach, conducting a gap analysis toward the envisioned PIMS, establishing the required scope of work, screening the PIMS applications market, and selecting suitable tools that satisfy expected deliverables, and implement PIMS applications. Saudi Aramco expects great benefits from implementing PIMS, e.g., enhancing safety, enhancing pipeline network robustness, optimizing inspection and maintenance expenditures, and facilitating pipeline management and the decision-making process. Saudi Aramco's new experience in adopting PIMS includes many challenges and lessons-learned associated with all of the PIMS development phases. These challenges include performing the gap analysis, conducting QA/QC sensitivity analysis for the acquired data, establishing the scope of work, selecting the appropriate applications and implementing PIMS.

Research on Connection and Function Reliability of the Oil＆Gas Pipeline System
Directory of Open Access Journals (Sweden)
Xu Bo
2017-01-01
Full Text Available Pipeline transportation is the optimal way for energy delivery in terms of safety, efficiency and environmental protection. Because of the complexity of pipeline external system including geological hazards, social and cultural influence, it is a great challenge to operate the pipeline safely and reliable. Therefore, the pipeline reliability becomes an important issue. Based on the classical reliability theory, the analysis of pipeline system is carried out, then the reliability model of the pipeline system is built, and the calculation is addressed thereafter. Further the connection and function reliability model is applied to a practical active pipeline system, with the use of the proposed methodology of the pipeline system; the connection reliability and function reliability are obtained. This paper firstly presented to considerate the connection and function reliability separately and obtain significant contribution to establish the mathematical reliability model of pipeline system, hence provide fundamental groundwork for the pipeline reliability research in the future.

This working group provided an update on provincial, federal and industry directions regarding the security of pipeline facilities. The decision to include security issues in the NEB Act was discussed as well as the Pipeline Security Management Assessment Project, which was created to establish a better understanding of existing security management programs as well as to assist the NEB in the development and implementation of security management regulations and initiatives. Amendments to the NEB were also discussed. Areas of pipeline security management assessment include physical safety management; cyber and information security management; and personnel security. Security management regulations were discussed, as well as implementation policies. Details of the Enbridge Liquids Pipelines Security Plan were examined. It was noted that the plan incorporates flexibility for operations and is integrated with Emergency Response and Crisis Management. Asset characterization and vulnerability assessments were discussed, as well as security and terrorist threats. It was noted that corporate security threat assessment and auditing are based on threat information from the United States intelligence community. It was concluded that the oil and gas industry is a leader in security in North America. The Trans Alaska Pipeline Incident was discussed as a reminder of how costly accidents can be. Issues of concern for the future included geographic and climate issues. It was concluded that limited resources are an ongoing concern, and that the regulatory environment is becoming increasingly prescriptive.

Gough, Clair; O'Keefe, Laura; Mander, Sarah
2014-01-01
This paper explores the response by members of the lay public to the prospect of an onshore CO 2 pipeline through their locality as part of a proposed CCS development and presents results from deliberative Focus Groups held along a proposed pipeline route. Although there is a reasonable level of general knowledge about CO 2 across the lay public, understanding of its specific properties is more limited. The main concerns expressed around pipelines focused on five areas: (i) safe operation of the pipeline; (ii) the risks to people, livestock and vegetation arising from the leakage of CO 2 from the pipeline; (iii) the innovative and ‘first of its kind' nature of the pipeline and the consequent lack of operational CO 2 pipelines in the UK to demonstrate the technology; (iv) impacts on coastal erosion at the landfall site; and (v) the potential disruption to local communities during pipeline construction. Participants expressed scepticism over the motivations of CO 2 pipeline developers. Trust that the developer will minimise risk during the route selection and subsequent construction, operation and maintenance of the pipeline is key; building trust within the local community requires early engagement processes, tailored to deliver a variety of engagement and information approaches. - Highlights: • Lay publics express good general knowledge of CO 2 but not of its specific properties. • Key concerns relate to risk and safety and ‘first of a kind' nature of CO 2 pipeline. • Group participants are sceptical about motivations of CO 2 pipeline developers. • Communities' trust in developer is a major element of their risk assessment

Rupture detection device for pipeline in reactor

1991-01-01
A difference between each of the pressures in a plurality of pipelines disposed in a shroud a reactor container and a pressure outside of the shroud is detected, thereby enabling safety and reliable detection even for simultaneous rapture and leakage of the pipelines. That is, a difference between the pressure of a steam phase outside of the shroud and a pressure in each of a plurality of low pressure injection pipelines in an emergency core cooling system opened to the inside of the shroud in the reactor container is detected by a difference pressure detector for each of them. Then, an average value for each of the pressure difference is determined, which is compared with the difference pressure obtained from each of the detectors in a comparator. Then, if openings should be caused by rupture, leakage or the like in any of the pipelines, the pressure in that pipeline is lowered to a vicinity of an atmospheric pressure and at the vapor phase pressure at the lowest. If the pressure is compared with the average value by the comparator, a negative difference is caused. Accordingly, an alarming unit generates an alarm based on the pressure difference signal, thereby enabling to specify the failed pipeline and provide an announce of the failure. (I.S.)

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.

CT-P10 (Truxima™) was recently approved as the world's first rituximab biosimilar product in the European Union (EU) and South Korea. To demonstrate biosimilarity of CT-P10 with the reference medicinal product (RMP), extensive 3-way similarity assessment has been conducted between CT-P10, EU-Rituximab and US-Rituximab, focusing on the physicochemical and biological quality attributes. A multitude of state-of-the-art analyses revealed that CT-P10 has identical primary and higher order structures compared to the original product. Purity/impurity profiles of CT-P10 measured by the levels of aggregates, fragments, non-glycosylated form and process-related impurities were also found to be comparable with those of RMPs. In terms of the post-translational modification, CT-P10 contains slightly less N-terminal pyro-glutamate variant, which has been known not to affect product efficacy or safety. Oligosaccharide profiling has revealed that, although CT-P10 contains the same conserved glycan species and relative proportion with the RMPs, the content of total afucosylated glycan in CT-P10 was slightly higher than in EU- or US-Rituximab. Nevertheless, the effect of the observed level of afucosylation in CT-P10 drug product on Fc receptor binding affinity or antibody-dependent cell-mediated cytotoxicity was found to be negligible based on the spiking study with highly afucosylated sample. Arrays of biological assays representative of known and putative mechanisms of action for rituximab have shown that biological activities of CT-P10 are within the quality range of RMPs. Recent results of clinical studies have further confirmed that the CT-P10 exhibits equivalent clinical efficacy and safety profiles compared to EU- and US-Rituximab. The current 3-way similarity assessment together with clinical study results confidently demonstrate that CT-P10 is highly similar with EU- and US-Rituximab in terms of physicochemical properties, biological activities, efficacy, and safety for

Pipelines are usually buried and have the function of long-distance transport. For this, special safety measures are requires. For example, pipelines of the chemical industry have defined locations that must be easily identifiable. Pipelines must be adapted to infrastructural and topographic boundary conditions, in consideration of environmental protection and because the pipeline may be damaged by external influences. Even minor releases of chemical substances may pollute water and soil and cause damage to humans. The contribution discusses the possible damage resulting from a pipeline leak. (orig.)

The Vulnerability Formation Mechanism and Control Strategy of the Oil and Gas Pipeline City
Chen, Y. L.; Han, L.
2017-12-01
Most of the pipelines of oil and gas pipelines in our country have been for more than 25 years. These pipes are buried underground and was difficult to daily test. In addition, it was vulnerable to environmental, corrosion and natural disasters, So there is a hidden nature of accidents. The rapid development of urbanization, population accumulation, dense building and insufficient safety range are all the reasons for the frequent accidents of oil and gas pipelines. Therefore, to appraise and know the safe condition of the city various regions oil and gas pipelines is vital significant. In order to ensure the safety of oil and gas pipeline city, this paper defines the connotation of oil and gas pipeline city vulnerability according to the previous research on vulnerability. Then from three perspectives of environment, structure and behavior, based on the analytical paradigm of “structure—vulnerability conduct—performance” about oil and gas, the influential indicators of vulnerable oil and gas pipelines were analysed, the vulnerability mechanism framework of Oil and gas pipeline city was also constructed. Finally, the paper proposed the regulating strategy of the vulnerability of the oil and gas pipeline city to decrease its vulnerability index, which can be realize the city’s vulnerability evaluation and provides new ideas for the sustainable development of the city.

Slurry pipelines: economic and political issues. A review
Energy Technology Data Exchange (ETDEWEB)
Banks, W. F.
1977-11-30
In the controversy surrounding the proposal to grant Federal eminent domain to coal-slurry pipelines, the fundamental issue is whether, on balance, such a grant is in the national interest. The principal subissues (peripheral issues) of economics, water supply and disposal, energy consumption and conservation, employment, safety, and environmental impact are analyzed. It is found that, as compared with unit trains, which are the only immediate alternative for movement of large quantities of Western coal, the pipelines are not against the national interest, except in the case of employment. It is concluded that, on balance, the pipelines are in the national interest and should be granted the power of Federal eminent domain.

New safety valve addresses environmental concerns
International Nuclear Information System (INIS)
Taylor, J.; Austin, R.
1992-01-01
This paper reports that Conoco Pipeline is using a unique relief valve to reduce costs while improving environmental protection at its facilities. Conoco Pipeline Co. Inc. began testing new relief valves in 1987 to present over-pressuring its pipelines while enhancing the safety, environmental integrity and profitability of its pipelines. Conoco worked jointly with Rupture Pin Technology Inc., Oklahoma City, to seek a solution to a series of safety, environmental, and operational risks in the transportation of crude oil and refined products through pipelines. Several of the identified problems were traced to a single equipment source: the reliability of rupture discs used at pipeline stations to relieve pressure by diverting flow to tanks during over-pressure conditions. Conoco's corporate safety and environmental policies requires solving problems that deal with exposure to hydrocarbon vapors, chemical spills or the atmospheric release of fugitive emissions, such as during rupture disc maintenance. The company had used rupture pin valves as vent relief devices in conjunction with development by Rick Austin of inert gas methods to protect the inner casing wall and outer carrier pipeline wall in pipeline road crossings. The design relies on rupture pin valves set at 5 psi to isolate vent openings from the atmosphere prior to purging the annular space between the pipeline and casing with inert gas to prevent corrosion.

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

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)

Pipeline leakages are very frequent and need to be detected as fast as possible to avoid safety and environment issues. Many leakage detection processes have been developed. Acoustic wave methods based on static pressure and dynamic pressure are both used for pipeline leakage detection. This study investigated a new pipeline leak detection method based on joint pressure and dynamic pressure. A dynamic pressure transmitter was designed based on a piezoelectric dynamic pressure sensor. The study showed that the dynamic pressure signal should be used for pipeline leak detection with a quick-change in pipeline internal pressure, while the static pressure signal provides better results with a slow-change of pipeline internal pressure. The in-field results showed that the location error of dynamic pressure is reduced to 80 m with a leakage ratio of 0.6 % pipeline throughput.

The Spanish authorities are in the process or reorganising the public nuclear sector in order to separate the promotional and research aspects of the uses of nuclear energy for peaceful purposes from the regulation and control of such activities. To this effect this Act sets up a Nuclear Safety Council which takes over part of the duties and the personnel of the Junta de Energia Nuclear provided for by the Act of 29th April 1964 on Nuclear Energy. The new Nuclear Safety Council is a body which is independent of the State central administration and has legal personality as well as its own financial resources required to carry out its duties. The latter comprise, inter alia, proposing to the Government the regulations required in matters of nuclear safety and radiation protection; this includes the setting-up of standards and criteria for the selection of nuclear installation sites, in consultation with the local competent bodies.

Overview of interstate hydrogen pipeline systems
International Nuclear Information System (INIS)
Gillette, J.L.; Kolpa, R.L.
2008-01-01
. The following discussion will focus on the similarities and differences between the two pipeline networks. Hydrogen production is currently concentrated in refining centers along the Gulf Coast and in the Farm Belt. These locations have ready access to natural gas, which is used in the steam methane reduction process to make bulk hydrogen in this country. Production centers could possibly change to lie along coastlines, rivers, lakes, or rail lines, should nuclear power or coal become a significant energy source for hydrogen production processes. Should electrolysis become a dominant process for hydrogen production, water availability would be an additional factor in the location of production facilities. Once produced, hydrogen must be transported to markets. A key obstacle to making hydrogen fuel widely available is the scale of expansion needed to serve additional markets. Developing a hydrogen transmission and distribution infrastructure would be one of the challenges to be faced if the United States is to move toward a hydrogen economy. Initial uses of hydrogen are likely to involve a variety of transmission and distribution methods. Smaller users would probably use truck transport, with the hydrogen being in either the liquid or gaseous form. Larger users, however, would likely consider using pipelines. This option would require specially constructed pipelines and the associated infrastructure. Pipeline transmission of hydrogen dates back to late 1930s. These pipelines have generally operated at less than 1,000 pounds per square inch (psi), with a good safety record. Estimates of the existing hydrogen transmission system in the United States range from about 450 to 800 miles. Estimates for Europe range from about 700 to 1,100 miles (Mohipour et al. 2004; Amos 1998). These seemingly large ranges result from using differing criteria in determining pipeline distances. For example, some analysts consider only pipelines above a certain diameter as transmission lines

Slovakia should be more active in pipeline projects
International Nuclear Information System (INIS)
Hirman, K.
2004-01-01
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

The continuous pipeline operators training and certification of the TRANSPETRO's Pipeline National Operations Control Center (CNCO) is an essential task aiming the efficiency and safety of the oil and derivatives transport operations through the Brazilian pipeline network. For this objective, a hydraulic simulator is considered an excellent tool that allows the creation of different operational scenarios for training the pipeline hydraulic behavior as well as for testing the operator's responses to normal and abnormal real time operational conditions. The hydraulic simulator is developed based on a pipeline simulation software that supplies the hydraulic responses normally acquired from the pipeline remote units in the field. The pipeline simulation software has a communication interface system that sends and receives data to the SCADA supervisory system database. Using the SCADA graphical interface to create and to customize human machine interfaces (HMI) from which the operator/instructor has total control of the pipeline/system and instrumentation by sending commands. Therefore, it is possible to have realistic training outside of the real production systems, while acquiring experience during training hours with the operation of a real pipeline. A pilot Project was initiated at TRANSPETRO - CNCO targeting to evaluate the hydraulic simulators advantages in pipeline operators training and certification programs. The first part of the project was the development of three simulators for different pipelines. The excellent results permitted the project expansion for a total of twenty different pipelines, being implemented in training programs for pipelines presently operated by CNCO as well as for the new ones that are being migrated. The main objective of this paper is to present an overview of the implementation process and the development of a training environment through a pipe simulation environment using commercial software.

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.

As a plant changes from the design phase to the operational phase, new regulations and standards apply. One such regulation is 10CFR50.59 on safety evaluations. Once an operating license is issued, it is mandatory to submit all applicable changes, tests, and experiments to the safety evaluation process. As preparation for this transition, Detroit Edison had procedures in place and conducted personnel training. Reviews of the safety engineering were conducted by the on-site review board. The off-site board delegated detailed reviews of most safety evaluations to the independent safety evaluation group (ISEG). The on-site group review included presentation of complete design packages by engineers. The ISEG and off-site review group's activity focused on safety evaluation. This paper addresses industry trends that were studied, Detroit Edison's recent actions, and industry issues related to 10CFR50.59 safety evaluations

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

Anon.
1983-01-01
Approximately 25% of the cost of a nuclear power plant are caused by the pipeline system, i.e. pipes and fixtures. This is an enourmous portion, demanding of the supplier and fitter of these components a very high safety standard. Against the background of the sociopolitical discussion on the safety of nuclear power plants it was a very useful idea of Mannesmann AG, one of the most important manufacturers in this sector, to lay open its quality assurance concept. On the occasion of the symposium ''Safe components for nuclear energy'' held for the expert press it was pointed out that the share of 17% electric energy coming at present from 15 nuclear power plants will increase in future for economic and ecologic reasons. So, it was maintained, the question is not about the ''pro and the con'', but exclusively about the safety standard for nuclear power plants. Specialists from the various branches of the undertaking informed on how this safety concept for the components pipelines and control equipment is realized. (orig./RW) [de

Highlights: • A large-scale full instrumented CO_2 test pipeline (258 m long, 233 mm id) has been developed. • The dynamic pressure evolutions near the orifice were recorded with differential pressure transducers. • The highly under-expanded jet flow structure in the near-field was studied in supercritical leakage. • The formation of the visible cloud, the distributions of temperature and concentration in the far-field were analysed. - Abstract: Long-distance CO_2 pipelines will be widely applied to transport captured CO_2 from fossil fuel fired power plants for subsequent sequestration. In the event of pipeline failure a large mass of the inventory may be discharged within a short time, this represents a significant hazard if leaks continue undetected. An important result of the risk assessment for a CO_2 pipeline is the safety distance. At present the lack of knowledge concerning near-field source terms and the far-field dispersion behavior of CO_2 leaking from pipelines can make the calculation of safety distances imprecise. Study of near-field source terms and dispersion behavior is therefore necessary and of paramount importance for assessing safety distances and the impact of CO_2 pipeline releases on the surrounding environment. In order to study CO_2 pipeline leakage, a large-scale pipeline set-up with a total length of 258 m and an internal diameter of 233 mm was constructed to study the near-field characteristics and dispersion behavior of supercritical CO_2 during sudden releases. The dynamic pressure near the orifice and CO_2 concentrations and temperatures within the downstream dispersion region were measured together with the pressures inside the pipeline. The under-expanded jet flow structure and phase transitions in the near-field were studied for supercritical CO_2 released though different orifice diameters (15 mm, 50 mm and Full Bore Rupture). The formation of the visible cloud, the distribution of cloud temperatures and CO_2

Rui, Zhenhua
This study analyzes historical cost data of 412 pipelines and 220 compressor stations. On the basis of this analysis, the study also evaluates the feasibility of an Alaska in-state gas pipeline using Monte Carlo simulation techniques. Analysis of pipeline construction costs shows that component costs, shares of cost components, and learning rates for material and labor costs vary by diameter, length, volume, year, and location. Overall average learning rates for pipeline material and labor costs are 6.1% and 12.4%, respectively. Overall average cost shares for pipeline material, labor, miscellaneous, and right of way (ROW) are 31%, 40%, 23%, and 7%, respectively. Regression models are developed to estimate pipeline component costs for different lengths, cross-sectional areas, and locations. An analysis of inaccuracy in pipeline cost estimation demonstrates that the cost estimation of pipeline cost components is biased except for in the case of total costs. Overall overrun rates for pipeline material, labor, miscellaneous, ROW, and total costs are 4.9%, 22.4%, -0.9%, 9.1%, and 6.5%, respectively, and project size, capacity, diameter, location, and year of completion have different degrees of impacts on cost overruns of pipeline cost components. Analysis of compressor station costs shows that component costs, shares of cost components, and learning rates for material and labor costs vary in terms of capacity, year, and location. Average learning rates for compressor station material and labor costs are 12.1% and 7.48%, respectively. Overall average cost shares of material, labor, miscellaneous, and ROW are 50.6%, 27.2%, 21.5%, and 0.8%, respectively. Regression models are developed to estimate compressor station component costs in different capacities and locations.

Zhang Guangli; Luo, Jinheng; Zhao Xinwei; Zhang Hua; Zhang Liang; Zhang Yi
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.

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.

Increased earthquake safety through optimised mounting concept
International Nuclear Information System (INIS)
Kollmann, Dieter; Senechal, Holger
2013-01-01
Since Fukushima, there has been intensive work on earthquake safety in all nuclear power plants. A large part of these efforts aim at the earthquake safety of safety-relevant pipeline systems. The problem with earthquake safety here is not the pipeline system itself but rather its mountings and connections to components. This is precisely the topic that the KAE dealt with in years of research and development work. It has developed an algorithm that determines the optimal mounting concept with a few iteration steps depending on arbitrary combinations of loading conditions whilst maintaining compliance with relevant regulations for any pipeline systems. With this tool at hand, we are now in a position to plan and realise remedial measures accurately with minimum time and hardware expenditure, and so distinctly improve the earthquake safety of safety-relevant systems.

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

Alpha-keto acid decarboxylases can convert keto acids to their corresponding aldehydes, which are often volatile aroma compounds. The gene encoding α-keto acid decarboxylase in Proteus mirabilis JN458 was cloned, and the enzyme overexpressed in Escherichia coli BL21 (DE3), purified in high yield, and characterised. The molecular weight is 62.291kDa by MALDI-TOF MS, and optimum activity at pH 6.0 and 40-50°C. The enzyme is a typical decarboxylase, dependent on thiamine diphosphate and Mg 2+ as cofactors. For the decarboxylation reaction, the enzyme displayed a broad substrate range. Kinetic parameters were determined using 4-methyl-2-oxopentanoic acid, phenyl pyruvate and 3-methyl-2-oxopentanoic acid as substrates. K m and k cat values for phenyl pyruvate were 0.62mM and 77.38s -1 , respectively, and the k cat /K m value was 124.81mM -1 s -1 . The enzyme properties suggest it may act effectively under cheese ripening conditions. Copyright © 2017. Published by Elsevier Ltd.

Load bearing capacity of welded joints between dissimilar pipelines with unequal wall thickness
Energy Technology Data Exchange (ETDEWEB)
Beak, Jonghyun; Kim, Youngpyo; Kim, Woosik [Korea Gas Corporation, Suwon (Korea, Republic of)
2012-09-15
The behavior of the load bearing capacity of a pipeline with unequal wall thickness was evaluated using finite element analyses. Pipelines with a wall thickness ratio of 1.22-1.89 were adopted to investigate plastic collapse under tensile, internal pressure, or bending stress. A parametric study showed that the tensile strength and moment of a pipeline with a wall thickness ratio less than 1.5 were not influenced by the wall thickness ratio and taper angle; however, those of a pipeline with a wall thickness ratio more than 1.5 decreased considerably at a low taper angle. The failure pressure of a pipeline with unequal wall thickness was not influenced by the wall thickness ratio and taper angle.

Solano, Rafael F.; Mendonca, Salete M. de [PETROBRAS S.A., Rio de Janeiro, RJ (Brazil); Franco, Luciano D.; Walker, Alastair; El-Gebaly, Sherif H. [INTECSEA, Rio de Janeiro, RJ (Brazil)
2009-12-19
The oil export pipelines of Marlim Sul field Module 3, Campus Basin, offshore Brazil, will operate in high pressure and temperature conditions, and will be laid on seabed crossing ten previously laid pipelines along the routes. In terms of thermo-mechanical design, these conditions turn out to be great challenges. In order to obtain initial results and recommendations for detail design, a preliminary thermo-mechanical design of pipelines was carried out as a fast-track design before the bid. This way, PETROBRAS can assess and emphasize the susceptibility of these lines to lateral buckling and pipeline walking behavior. Therefore, PETROBRAS can present a preliminary mitigation strategy for lateral buckling showing solutions based on displacement controlled criteria and by introducing buckle initiation along the pipeline using distribution buoyancy. Besides that, axial displacements and loads at the pipeline ends can be furnished also in order to provide a basis for the detailed design. The work reported in this paper follows the SAFEBUCK JIP methodology and recommendation, which were used to determine the allowable strain and maximum allowable VAS (Virtual Anchor Spacing) considered in the buckling mitigation strategy. The paper presents also the formation of uncontrolled buckles on the seabed and the propensity for pipeline walking in its sections between buckles. The buckling mitigation strategy established in this preliminary design confirms that the oil pipeline specifications are adequate to maintain integrity during design life. (author)

In this work, effects of pH value on the electrochemical and stress corrosion cracking (SCC) behavior of X70 pipeline steel in the dilute bicarbonate solutions were investigated using electrochemical measurements, slow strain rate tensile tests and surface analysis techniques. Decrease of the solution pH from 6.8 to 6.0 promotes the anodic dissolution and cathodic reduction simultaneously. Further decrease of the pH value mainly accelerates the cathodic reduction of X70 pipeline steel. As a result, when the solution pH decreases form 6.8 to 5.5, SCC susceptibility decreases because of the enhancement of the anodic dissolution. When the solution pH decreases from 5.5 to 4.0, SCC susceptibility increases gradually because of the acceleration of cathodic reactions.

Rhodobacter sphaeroides NMBL-02, photosynthetic purple non sulfur (PNS) bacteria and associated Bacillus firmus NMBL-03 were isolated from water sample collected from 15-20 inches beneath the surface of ponds from Northern region of India in modified Sistrom's media (120 ml) containing 3 g/L malate and 1.2 g/L ammonium sulfate. The isolation was done in air tight serum bottles (120 ml) under tungsten bulb (1.8 kLux light intensity) at 30 oC ± 2 oC. The PNS and heterotrophic bacteria associated with the culture was purified by clonal selection method and characterized by 16S rDNA sequencing. The PNS isolate was identified as Rhodobacter sphaeroides NMBL-02 (ID: 1467407, Accession BANKIT: JN256030) and associated heterotroph as Bacillus firmus NMBL-03 (Gene Bank Accession no.: JN 256029). The effect of initial medium pH on optimization of hydrogen production was investigated in batch process. The maximum hydrogen potential and hydrogen production rate was 2310 ± 55 ml/L and 4.75 ml/L culture/h respectively using glutamate (1.7 mmol/L) as nitrogen source and malate (22.38 mmol/L) as carbon source with 76.39% malate conversion efficiency at initial medium pH 5.0. This co-culture has the ability to produce significant amount of hydrogen in the pH range of 5.0 to 10.0 with 76.39% to 35.71% malate conversion respectively.

2007-07-01
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.

Oil pipeline performance review, 1990
International Nuclear Information System (INIS)
1990-01-01
This paper reviews the environmental performance of Canadian oil pipelines in spill prevention and control in 1990 and compares it with that in 1989. In 1990, in-service length of the systems reporting increased to 34,907 km. Traffic volume was 235 million m 3 . Failures dropped 16% from 1989 to 36. Equipment failures accounted for 47%, corrosion for 22% and operational error for 19% of the failures. Repair, damage and clean-up costs were considerably higher at $5,302,000, of which one external corrosion failure contributed $4,500,000. The average spill size was 130 m 3 with 72 m 3 recovered for a 55.4% recovery rate. No injuries resulted from the failures. An 11 year statistical summary of oil pipeline performance data is included. 3 figs., 5 tabs

2006-05-01
The crystallogenesis of bacteriophage P22 tail-fiber gp26 is described. To study possible pH-induced conformational changes in gp26 structure, native trimeric gp26 has been crystallized at acidic pH (4.6) and a chimera of gp26 fused to maltose-binding protein (MBP-gp26) has been crystallized at neutral and alkaline pH (7-10). Gp26 is one of three phage P22-encoded tail accessory factors essential for stabilization of viral DNA within the mature capsid. In solution, gp26 exists as an extended triple-stranded coiled-coil protein which shares profound structural similarities with class I viral membrane-fusion protein. In the cryo-EM reconstruction of P22 tail extracted from mature virions, gp26 forms an ∼220 Å extended needle structure emanating from the neck of the tail, which is likely to be brought into contact with the cell’s outer membrane when the viral DNA-injection process is initiated. To shed light on the potential role of gp26 in cell-wall penetration and DNA injection, gp26 has been crystallized at acidic, neutral and alkaline pH. Crystals of native gp26 grown at pH 4.6 diffract X-rays to 2.0 Å resolution and belong to space group P2{sub 1}, with a dimer of trimeric gp26 molecules in the asymmetric unit. To study potential pH-induced conformational changes in the gp26 structure, a chimera of gp26 fused to maltose-binding protein (MBP-gp26) was generated. Hexagonal crystals of MBP-gp26 were obtained at neutral and alkaline pH using the high-throughput crystallization robot at the Hauptman–Woodward Medical Research Institute, Buffalo, NY, USA. These crystals diffract X-rays to beyond 2.0 Å resolution. Structural analysis of gp26 crystallized at acidic, neutral and alkaline pH is in progress.

This paper presents details of an Engineering Critical Assessment (ECA) performed to develop girth weld flaw acceptance criteria for the PETROBRAS Camarupim Pipeline which was installed in Espirito Santo Basin, ES, offshore Brazil in May 2008 by Global Industries. The pipeline was constructed using 24-inch diameter API Grade X65 pipe with wall thicknesses of 0.875-inch (22.2 mm) and 1.00 inch (25.4 mm). Although the Camarupim pipeline will initially transport sweet gas there is the potential for mildly sour service operation in mid to late life. To assess the effect of sour service on the material toughness properties a series of slow strain rate fracture toughness tests were performed in a Project representative sour service environment. In addition the results of sour service fatigue crack growth tests were analyzed to develop a conservative sour service fatigue crack growth law for the ECA analysis. (author)

Pipesworld : applying planning systems to pipeline transportation
Energy Technology Data Exchange (ETDEWEB)
Milidiu, R.L.; Santos Liporace, F. [Pontificia Univ. Catolica, Rio de Janeiro (Brazil). Dept. de Informatica
2004-07-01
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.

To identify variants for multiple myeloma risk, we conducted a genome-wide association study with validation in additional series totaling 4,692 cases and 10,990 controls. We identified four risk loci at 3q26.2 (rs10936599, P=8.70x10-14), 6p21.33 (rs2285803, PSORS1C2; P= 9.67x10-11), 17p11.2 (rs4273077, TNFRSF13B; P=7.67x10-9) and 22q13.1 (rs877529, CBX7; P=7.63x10-16). These data provide further evidence for genetic susceptibility to this B-cell hematological malignancy and insight into the biological basis of predisposition. PMID:23955597

Waxy crude is characterized by its high pour point. Pipeline blockage may occur after prolonged shutdown of a pipeline due to crude oil gelation. Another flow assurance problem is the instable operation at a flow rate below the lowest allowable operation flow rate which is dependent on heat transfer of the pipeline and the viscosity vs. temperature relation of the crude pumped. Besides, for pipelines with thick wax deposition layer, massive depletion of wax deposit in some cases such as pipeline restart at high expelling pressure may also result in blockage of the pipeline, and the pig may be jammed during pigging as a result of thick wax deposition. Conventionally, assessment of these risks has been made by using the deterministic approach. However, many related physical quantities are subject to uncertainty and contribute to reliability of flow assurance. Therefore, the probabilistic approach is suggested and a framework of reliability based assessment of flow assurance of waxy crude pipelines is proposed in this paper. Discussions are also made on the limit state functions and target safety level. In the future study, development of an efficient and robust stochastic-numerical method is crucial. (author)

A method of quantitative risk assessment for transmission pipeline carrying natural gas
International Nuclear Information System (INIS)
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

Simplified Technique for Predicting Offshore Pipeline Expansion
Seo, J. H.; Kim, D. K.; Choi, H. S.; Yu, S. Y.; Park, K. S.
2018-06-01
In this study, we propose a method for estimating the amount of expansion that occurs in subsea pipelines, which could be applied in the design of robust structures that transport oil and gas from offshore wells. We begin with a literature review and general discussion of existing estimation methods and terminologies with respect to subsea pipelines. Due to the effects of high pressure and high temperature, the production of fluid from offshore wells is typically caused by physical deformation of subsea structures, e.g., expansion and contraction during the transportation process. In severe cases, vertical and lateral buckling occurs, which causes a significant negative impact on structural safety, and which is related to on-bottom stability, free-span, structural collapse, and many other factors. In addition, these factors may affect the production rate with respect to flow assurance, wax, and hydration, to name a few. In this study, we developed a simple and efficient method for generating a reliable pipe expansion design in the early stage, which can lead to savings in both cost and computation time. As such, in this paper, we propose an applicable diagram, which we call the standard dimensionless ratio (SDR) versus virtual anchor length (L A ) diagram, that utilizes an efficient procedure for estimating subsea pipeline expansion based on applied reliable scenarios. With this user guideline, offshore pipeline structural designers can reliably determine the amount of subsea pipeline expansion and the obtained results will also be useful for the installation, design, and maintenance of the subsea pipeline.

The GASENE project is the largest gas pipeline constructed in Brazil in the past 10 years, it interconnects the southeast to the northeast of Brazil. The Cacimbas Catu Gas Pipeline (GASCAC) is a part of the project; it has a 28 inch diameter and is 958 km long. The aim of this paper is to present the construction and assembly process undertaken to meet the deadline and complete the GASCAC to a high quality standard. The main challenges of this project were its length, the short period for completion and the numerous geological and man-made features along the pipeline route. To overcome these difficulties, technologies that had never been used in Brazil before were employed, such as vacuum pipe lifting, bag weights and automatic welding. The GASCAC project was completed in time and with to a high standard of quality, demonstrating that strategic planning and the use of new technologies can increase productivity, quality and safety.

Frequency spectrum method-based stress analysis for oil pipelines in earthquake disaster areas.
Directory of Open Access Journals (Sweden)
Xiaonan Wu
Full Text Available When a long distance oil pipeline crosses an earthquake disaster area, inertial force and strong ground motion can cause the pipeline stress to exceed the failure limit, resulting in bending and deformation failure. To date, researchers have performed limited safety analyses of oil pipelines in earthquake disaster areas that include stress analysis. Therefore, using the spectrum method and theory of one-dimensional beam units, CAESAR II is used to perform a dynamic earthquake analysis for an oil pipeline in the XX earthquake disaster area. This software is used to determine if the displacement and stress of the pipeline meet the standards when subjected to a strong earthquake. After performing the numerical analysis, the primary seismic action axial, longitudinal and horizontal displacement directions and the critical section of the pipeline can be located. Feasible project enhancement suggestions based on the analysis results are proposed. The designer is able to utilize this stress analysis method to perform an ultimate design for an oil pipeline in earthquake disaster areas; therefore, improving the safe operation of the pipeline.

Failure free design of supporting systems for pipe lines carrying highly toxic or radioactive liquids at very high temperature is an important issue in the safety aspect for a nuclear power plant installation which is a key topic for researchers all around the world. Generally, these pipeline systems are designed to be held rigid by conventional snubber supports for protection from earthquakes. The piping design must balance seismic deformations and other deformations due to thermal effect. A rigid pipeline system using conventional snubber supports always leads to an increase in thermal stresses; hence a rational seismic design for pipeline supporting systems becomes essential. Contrary to this rigid design, it is possible to design a flexible pipeline system and to decrease the seismic response by increasing the damping through the use of passive energy absorbing elements, which dissipate vibration energy. This paper presents the experimental and analytical studies carried out on modeling yielding type elasto-plastic passive energy-absorbing elements to be used in a passive energy-dissipating device for the control of large seismic deformations of pipelines subjected to earthquake loading.

PETROBRAS E and P department (up-stream segment) had assigned first contract for pipeline inspection using smart pigs in 1995. Up to this time only TRANSPETRO (down-stream segment) had an experience with those inspections mainly focused on first generation tools. On this contract, it was first time required high resolution tools, which had bigger defect detection capability and sizing accuracy as advantages but with higher cost. It was regarded necessary due to high costs involved on a virtual sub sea survey or repair. The investment was regarded fair as there is no way to establish correlation digs as well as normally done after on shore pipelines surveys. Actually the first internal inspection was carried out in 1997. From this period it has been realized the enormous importance on verifying all platforms installations and all procedures involving cleaning runs. We have taken many lessons from these inspections. Commissioning using all kinds of cleaning pigs (some was invented) that could be specially contracted on scaling removing jobs; diesel batch to make easy US pigs inspection, cleaning steps that should be gradual to allow receiving of debris without disturbing platforms process efficiency; special tools designed in-house to meet some specific installations requirements as limited pigability; were some issues that demanded efforts on this period. PETROBRAS/E and P through its Campos Basin Production Unit has been strongly involved on looking for solutions to keep its sub sea pipeline net integrity; a strategic asset that will guarantee the Brazilian development on oil and gas production.

Effect of pre-deformation on the fatigue crack initiation life of X60 pipeline steel
International Nuclear Information System (INIS)
Zheng, M.; Luo, J.H.; Zhao, X.W.; Bai, Z.Q.; Wang, R.
2005-01-01
It is impossible to keep petroleum and natural gas transmission pipelines free from defects in the manufacturing, installation and servicing processes. The damage might endanger the safety of pipelines and even shorten their service life; gas or petroleum release due to defects may jeopardise the surrounding ecological environments with associated economic and life costs. Pre-tensile deformation of X60 steel is employed to experimentally simulate the influence of dents on the fatigue crack initiation life. The investigation indicates that the fatigue crack initiation life of pre-deformed X60 pipeline steel can be assessed by a previously proposed energetic approach. The threshold for crack initiation increases with the pre-deformation due to a strain hardening effect, while the fatigue resistant factor exhibits a maximum with pre-deformation owing to its special dependence on fracture strain and fracture strength. The result is expected to be beneficial to the understanding of the effect of damage on the safety of pipelines and fatigue life prediction

Water reuse has become increasingly important for sustainable water management. Currently, its application is primarily constrained by the potential health risks. Presently there is limited knowledge regarding the presence and fate of opportunistic pathogens along reuse water distribution pipelines. In this study opportunistic human pathogens Legionella spp., L. pneumophila and Mycobacterium avium complex were detected using real-time polymerase chain reaction along two South Australian reuse water distribution pipelines at maximum concentrations of 10⁵, 10³ and 10⁵ copies/mL, respectively. During the summer period of sampling the concentration of all three organisms significantly increased (P < 0.05) along the pipeline, suggesting multiplication and hence viability. No seasonality in the decrease in chlorine residual along the pipelines was observed. This suggests that the combination of reduced chlorine residual and increased water temperature promoted the presence of these opportunistic pathogens.

Onshore pipelines have traditionally been designed with a deterministic stress based methodology. The changing operating environment has however imposed many challenges to the pipeline industry, including heightened public awareness of risk, more challenging natural hazards and increased economic competitiveness. To meet the societal expectation of pipeline safety and enhance the competitiveness of the pipeline industry, significant efforts have been spent for the development of reliability-based design and assessment (RBDA) methodology. This paper will briefly review the technology development in the RBDA area and the focus will be on the progresses in the past years in standard development within the American Society of Mechanical Engineers (ASME) and the Canadian Standard Association (CSA) organizations.

2010-07-01
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.

ITT Industries Inc., Physical Sciences Inc., and LaSen Inc. are 3 American companies leading the way to find more efficient methods for identifying leaks from natural gas pipelines. Edmonton-based Synodon Inc. has recently joined the leaders with its newly developed and more sensitive equipment that it hopes to have on the market by the summer of 2006. Leak detection technology was first developed in 1993 in response to concerns about the reliability of aging pipeline infrastructure. In addition to safety concerns, there are concerns over global warming. Methane is a potential greenhouse gas and the United states Environmental Protection Agency estimates that 300 billion cubic feet escape into the atmosphere every year from pipeline leaks. The 2002 Pipeline Safety Improvement Bill in the United States stipulates that leak inspections must be conducted up to 4 times per year in densely populated areas. Violators face fines as high as $1 million. In response to the pipeline safety bill, Synodon raised private equity financing to commercialize an airborne leak detection technology stemming from Canada's space program. In the United States, leak detection technologies that appear likely to take 5 to 20 years for commercialization have been been financed by the Department of Energy and the Office of Pipeline Safety. This paper summarized 5 leak detection prototypes, including ITT's Airborne Natural Gas Emission LiDAR (ANGEL) system which targets high-pressure, long-distance pipelines in North America, LaSen's Airborne LiDAR Pipeline Inspection System (ALPIS) based on DIAL Technology, and a hand-held remote methane leak detector developed jointly by Physical Sciences Inc. of Massachusetts and Houston-based Heath Consultants Inc. Synodon claims that hand-held detectors are too slow and that LiDAR systems still aren't reliable for detection of leaks much below 500 scf/h. Synodon's realSens technology may be more difficult to develop, but it detects

Leaks appear frequently in pipelines, raising the possibility of safety issues. The detection of pipeline leakage is very important for the pipeline industry. This paper investigated a leak detection method on a long pipeline using a dynamic pressure sensor. A new leakage system is proposed based on the measurements obtained from this dynamic pressure sensor. The data were analyzed using the wavelet transformation method. First, the signal provided by the pressure sensor its denoised and then leaks are detected from the presence of singularities in the signal. Field tests were carried out on a product oil pipeline of 94 km length. The in-field test results showed that the minimum ratio of detectable leakage is 0.6 % of throughput and the location error is below 300 m. The response time is less than 120 seconds. This new system has been applied in 5000 km pipelines in China and is proving its efficiency in detecting leak points.

Folga, S. M.; Decision and Information Sciences
2007-11-01
The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by

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.

Incidents caused by fire and other thermal events can heat energetic materials that may lead to thermal explosion and result in structural damage and casualty. Thus, it is important to understand the response of energetic materials to thermal insults. The One-Dimensional-Time to Explosion (ODTX) system at the Lawrence Livermore National Laboratory (LLNL) has been used for decades to characterize thermal safety of energetic materials. In this study, an integration of a pressure monitoring element has been added into the ODTX system (P-ODTX) to perform thermal explosion (cook-off) experiments (thermal runaway) on PETN powder, PBX-9407, LX-10-2, LX-17-1, and detonator samples (cup tests). The P-ODTX testing generates useful data (thermal explosion temperature, thermal explosion time, and gas pressures) to assist with the thermal safety assessment of relevant energetic materials and components. This report summarizes the results of P-ODTX experiments that were performed from May 2015 to July 2017. Recent upgrades to the data acquisition system allows for rapid pressure monitoring in microsecond intervals during thermal explosion. These pressure data are also included in the report.

2015-12-01
Full Text Available In the petroleum, natural gas and petrochemical industries, great attention is being paid to safety, reliability and maintainability of equipment. There are a number of technologies to monitor, control, and maintain gas, oil, water, and sewer pipelines. The paper focuses on operational modal analysis (OMA application for condition monitoring of operating pipelines. Special focus is on the topicality of OMA for definition of the dynamic features of the pipeline (frequencies and mode shapes in operation. The research was conducted using two operating laboratory models imitated a part of the operating pipeline. The results of finite-element modeling, identification of pipe natural modes and its modification under the influence of virtual failure are discussed. The work considers the results of experimental research of dynamic behavior of the operating pipe models using one of OMA techniques and comparing dynamic properties with the modeled data.

Zhou, Anbo; Zhang, Yeting; Sun, Yazhou; Xing, Jinchuan
2018-05-01
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. Supplementary data are available at Bioinformatics online.

The external anticorrosive coating is the shelter for preventing steel pipelines from Corrosive damage. A number of pipelines face severe corrosive problems for the performance decrease of the coating, especially during long-term services, which usually led to safety accidents. To solve the detection problem about the defect of anticorrosive layer for pipeline, a new detection method for anticorrosive layer of pipelines based on Ultrasonic Guided Wave was proposed in the paper. The results from the investigation show a possibility of using the Ultrasonic Guided Wave method for detecting the damage of pipeline’s External Anticorrosive Coating.

United States petroleum pipelines: An empirical analysis of pipeline sizing
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.

As a new type of submarine pipeline, the piggyback pipeline has been gradually adopted in engineering practice to enhance the performance and safety of submarine pipelines. However, limited simulation work and few experimental studies have been published on the scour around the piggyback pipeline under steady current. This study numerically and experimentally investigates the local scour of the piggyback pipe under steady current. The influence of prominent factors such as pipe diameter, inflow Reynolds number, and gap between the main and small pipes, on the maximum scour depth have been examined and discussed in detail. Furthermore, one formula to predict the maximum scour depth under the piggyback pipeline has been derived based on the theoretical analysis of scour equilibrium. The feasibility of the proposed formula has been effectively calibrated by both experimental data and numerical results. The findings drawn from this study are instructive in the future design and application of the piggyback pipeline.

Liang, Wei; Zhang, Laibin [Research Center of Oil and Gas Safety Engineering Technology, China University of Petroleum, Beijing, (China)
2010-07-01
The detection of leaks on petroleum pipeline is a very important safety issue. Several studies were commissioned to develop new monitoring procedures for leakage detection. This paper sets out a new leak detection process. The approach developed took into consideration steady and transient states. The study investigated leak diagnosis problems in product pipelines using multi-sensor measurements (pressure, flux, density and temperature). The information collected from each sensor was considered as pieces of evidence that describe the operational conditions of the pipeline. The Dempster-Shafer (D-S) theory is used to associate multi-sensor data to pipe health indices. Experimental pressure and flow rate data were recorded using a Pipeline Leak Detection System (PLDS) acquisition card and used to verify the accuracy and reliability of this new detection method. The results showed that the degree of credibility was a high as 0.877. It was also found that multi-feature information fusion improves recognition of pipeline conditions.

A Novel Method to Enhance Pipeline Trajectory Determination Using Pipeline Junctions.
Sahli, Hussein; El-Sheimy, Naser
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.

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

Reliability evaluation of oil pipelines operating in aggressive environment
Magomedov, R. M.; Paizulaev, M. M.; Gebel, E. S.
2017-08-01
In connection with modern increased requirements for ecology and safety, the development of diagnostic services complex is obligatory and necessary enabling to ensure the reliable operation of the gas transportation infrastructure. Estimation of oil pipelines technical condition should be carried out not only to establish the current values of the equipment technological parameters in operation, but also to predict the dynamics of changes in the physical and mechanical characteristics of the material, the appearance of defects, etc. to ensure reliable and safe operation. In the paper, existing Russian and foreign methods for evaluation of the oil pipelines reliability are considered, taking into account one of the main factors leading to the appearance of crevice in the pipeline material, i.e. change the shape of its cross-section, - corrosion. Without compromising the generality of the reasoning, the assumption of uniform corrosion wear for the initial rectangular cross section has been made. As a result a formula for calculation the probability of failure-free operation was formulated. The proposed mathematical model makes it possible to predict emergency situations, as well as to determine optimal operating conditions for oil pipelines.

We present a frequentist analysis of the parameter space of the pMSSM10, in which the following 10 soft SUSY-breaking parameters are specified independently at the mean scalar top mass scale M SUSY ≡√(m t 1 m t 2 ): the gaugino masses M 1,2,3 , the 1st-and 2nd-generation squark masses m q 1 =m q 2 , the third-generation squark mass m q 3 , a common slepton mass M l and a common trilinear mixing parameter A, the Higgs mixing parameter μ, the pseudoscalar Higgs mass M A and tan β. We use the MultiNest sampling algorithm with ∝1.2 x 10 9 points to sample the pMSSM10 parameter space. A dedicated study shows that the sensitivities to strongly-interacting SUSY masses of ATLAS and CMS searches for jets, leptons+E T signals depend only weakly on many of the other pMSSM10 parameters. With the aid of the Atom and Scorpion codes, we also implement the LHC searches for EW-interacting sparticles and light stops, so as to confront the pMSSM10 parameter space with all relevant SUSY searches. In addition, our analysis includes Higgs mass and rate measurements using the HiggsSignals code, SUSY Higgs exclusion bounds, the measurements B-physics observables, EW precision observables, the CDM density and searches for spin-independent DM scattering. We show that the pMSSM10 is able to provide a SUSY interpretation of (g-2) μ , unlike the CMSSM, NUHM1 and NUHM2. As a result, we find (omitting Higgs rates) that the minimum χ 2 /d.o.f.=20.5/18 in the pMSSM10, corresponding to a χ 2 probability of 30.8 %, to be compared with χ 2 /d.o.f.=32.8/24(31.1/23)(30.3/22) in the CMSSM (NUHM1) (NUHM2). We display 1-dimensional likelihood functions for SUSY masses, and show that they may be significantly lighter in the pMSSM10 than in the CMSSM, NUHM1 and NUHM2. We discuss the discovery potential of future LHC runs, e + e - colliders and direct detection experiments.

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)

Leak detection for city gas pipelines based on instantaneous energy distribution characteristics
Energy Technology Data Exchange (ETDEWEB)
Zhigang, Chen [Deijing University of Civil Engineering and Architecture, Beijing, (China)
2010-07-01
Many natural gas pipelines are used in our cities. The development of efficient leakage detection systems is fundamental for safety issues avoidance. This paper investigated a new solution to the leak detection problem in city gas pipelines based on instantaneous energy distribution. In a theoretical approach, the Hilbert-Huang transform (HHT) was used to provide the instantaneous energy distribution feature of an unstable pressure signal. The signal noise was eliminated thanks to the instantaneous energy contribution. A leakage detection model with instantaneous energy distribution (IED) was then established. The correlation coefficients of instantaneous energy distribution were through correlation analysis. It was found that in different pipeline states, the instantaneous energy distribution characteristics are different. A strong correlation of IED signal characteristics was found of the two ends of a city gas pipeline in the same operation. The test results demonstrated the reliability and validity of the method.

US DOE Pipeline Unplugging Requirements Development
International Nuclear Information System (INIS)
Rivera, J.; McDaniel, D.
2009-01-01
Department of Energy (DOE) sites around the country have an ongoing effort to transport and process several tons of radioactive waste in the form of slurry (liquids and solids) from storage tanks to processing facilities. The system of pipes used for the transportation of this waste needs technology for maintenance and for the prevention (and correction) of pipeline plugging. The unplugging technologies that have been tested and evaluated at Florida International University include ones from NuVision Engineering, AIMM and AquaMiser. NuVision's technology acts as an ocean wave does on beach erosion. It can operate on a long pipeline that has drained down below a blockage. AIMM Technology's Hydrokinetic TM process uses a sonic resonance with a cleaning water stream. This sonic resonance travels through the water stream and transfers vibration to both the pipe and the blockage. The AquaMiser line of water blasting equipment combines 15,000- to 40,000-psi water injection technology to unplug pipelines. Some sites cannot allow this level of pressure in their pipes. After reviewing the results of every test, including the benefits, advantages and disadvantages of each technology, requirements were developed for pressure, personnel training, environmental concerns, safety, and compatibility with current systems, operability, reliability, maintainability and cost.

InGaN quantum well based light emitters grown on (0001) GaN suffer from poor quantum efficiencies with increasing indium mole fraction due to strong polarization fields along the polar crystal orientation. This effect can be greatly reduced by growing on semi- and non-polar GaN orientations. Semipolar (11 anti 22) GaN layers were deposited by metalorganic vapour phase epitaxy on (10 anti 10) sapphire. After sapphire substrate nitridation at 1000 C, a GaN nucleation layer was deposited at high temperature, followed by the deposition of 1.5 nm thick GaN buffer layers. The samples show predominantly (11 anti 22) orientation with a small fraction of (10 anti 13) oriented domains. With increasing nitridation layer thickness the (10 anti 13) phase is suppressed leading to a very smooth surface morphology (rms roughness < 4nm). PL measurements show dominant basel plane stacking fault (BSF) I{sub 1} luminescence without any other defects. Transmission electron microscopy measurements reveal a high BSF density. The FWHM of the X-ray diffraction rocking curve measurements of the (1122) reflection decreases to 1193 arcsec and 739 arcsec along [1 anti 100] and [11 anti 23] respectively with increasing nucleation temperature. Using high temperature nucleation smooth and homogeneous (11 anti 22) phase GaN layers have been obtained.

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.

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.

Historical analysis of US pipeline accidents triggered by natural hazards
Girgin, Serkan; Krausmann, Elisabeth
2015-04-01
Natural hazards, such as earthquakes, floods, landslides, or lightning, can initiate accidents in oil and gas pipelines with potentially major consequences on the population or the environment due to toxic releases, fires and explosions. Accidents of this type are also referred to as Natech events. Many major accidents highlight the risk associated with natural-hazard impact on pipelines transporting dangerous substances. For instance, in the USA in 1994, flooding of the San Jacinto River caused the rupture of 8 and the undermining of 29 pipelines by the floodwaters. About 5.5 million litres of petroleum and related products were spilled into the river and ignited. As a results, 547 people were injured and significant environmental damage occurred. Post-incident analysis is a valuable tool for better understanding the causes, dynamics and impacts of pipeline Natech accidents in support of future accident prevention and mitigation. Therefore, data on onshore hazardous-liquid pipeline accidents collected by the US Pipeline and Hazardous Materials Safety Administration (PHMSA) was analysed. For this purpose, a database-driven incident data analysis system was developed to aid the rapid review and categorization of PHMSA incident reports. Using an automated data-mining process followed by a peer review of the incident records and supported by natural hazard databases and external information sources, the pipeline Natechs were identified. As a by-product of the data-collection process, the database now includes over 800,000 incidents from all causes in industrial and transportation activities, which are automatically classified in the same way as the PHMSA record. This presentation describes the data collection and reviewing steps conducted during the study, provides information on the developed database and data analysis tools, and reports the findings of a statistical analysis of the identified hazardous liquid pipeline incidents in terms of accident dynamics and

Hybrid laser-gas metal arc welding (GMAW) of high strength steel gas transmission pipelines
Energy Technology Data Exchange (ETDEWEB)
Harris, Ian D.; Norfolk, Mark I. [Edison Welding Institute (EWI), Columbus, Ohio (United States)
2009-07-01
Hybrid Laser/arc welding process (HLAW) can complete 5G welds, assure weld soundness, material properties, and an acceptable geometric profile. Combining new lasers and pulsed gas metal arc welding (GMAW-P) has led to important innovations in the HLAW process, increasing travel speed for successful root pass welding. High power Yb fiber lasers allow a 10 kW laser to be built the size of a refrigerator, allowing portability for use on the pipeline right-of-way. The objective was to develop and apply an innovative HLAW system for mechanized welding of high strength, high integrity, pipelines and develop 5G welding procedures for X80 and X100 pipe, including mechanical testing to API 1104. A cost-matched JIP developed a prototype HLAW head based on a commercially available bug and band system (CRC-Evans P450). Under the US Department of Transportation (DOT) project, the subject of this paper, the system was used to advance pipeline girth welding productivity. External hybrid root pass welding achieved full penetration welds with a 4-mm root at a travel speed of 2.3-m/min. Welds were made 'double down' using laser powers up to 10 kW and travel speeds up to 3-m/min. The final objective of the project was to demonstrate the hybrid LBW/GMAW system under simulated field conditions. (author)

Electrostatic sensors applied to the measurement of electric charge transfer in gas-solids pipelines
International Nuclear Information System (INIS)
Woodhead, S R; Denham, J C; Armour-Chelu, D I
2005-01-01
This paper describes the development of a number of electric charge sensors. The sensors have been developed specifically to investigate triboelectric charge transfer which takes place between particles and the pipeline wall, when powdered materials are conveyed through a pipeline using air. A number of industrial applications exist for such gas-solids pipelines, including pneumatic conveyors, vacuum cleaners and dust extraction systems. The build-up of electric charge on pipelines and powdered materials can lead to electrostatic discharge and so is of interest from a safety viewpoint. The charging of powders can also adversely affect their mechanical handling characteristics and so is of interest to handling equipment engineers. The paper presents the design of the sensors, the design of the electric charge test rig and electric charge measurement test results

The PPG-1/PGP-1 crude pipeline links Pargo and Garoupa platforms at the Campos Basin. Garoupa process the crude removing water and transferring it to the coast. During 10 years this pipeline had operated with more than 20% of water. In 2001, the pipeline was surveyed with a MFL pig. The results showed internal corrosion in almost the entire 22 inches pipeline concentrated on its bottom part (channeling corrosion). This type of indication has a high difficult on sizing using MFL tools. The logistic to replace the damaged pipeline was started but before that, the pipeline was surveyed with a US pig to improve the sizing of all defects. The results of the US pig confirmed the MFL report and were decided to keep all tasks in order to replace the corroded segment. At that time, a new inspection pig was under development on PETROBRAS Research Center in cooperation with PUC-Rio/CETUC. It was decided run this tool in that pipeline to compare its results against the two most common methods used for pipelines inspections. (author)

A 3D parametric finite element model of the pipeline and soil is established using finite element method to perform the failure analysis of natural gas buried X65 steel pipeline under deflection load. The pipeline is assumed to be loaded in a parabolic deflection displacement along the axial direction. Based on the true stress-strain constitutive relationship of X65 steel, the elastic-plastic finite element analysis employs the arc-length algorithm and non-linear stabilization algorithm respectively to simulate the strain softening properties of pipeline after plastic collapse. Besides, effects of the soil types and model sizes on the maximum deflection displacement of pipeline are investigated. The proposed finite element method serves as a base available for the safety design and evaluation as well as engineering acceptance criterion for the failure of pipeline due to deflection.

Anon.
1995-01-01
European pipelines in 1993 spilled as much crude oil and petroleum products as in any year since 1971, when statistics first began to be reported. Final cost of cleanup will exceed $10 million, by far the most ever spent by western European oil pipelines operating on land. This cost figure is only preliminary: costs for three spills totaling nearly 2,600 cu m (approximately 16,380 bbl; 43.6% of total spilled) had not been reported through November 1994. Ten incidents of oil spills from pipelines occurred in 1993, compared with seven for 1992 and an average of 12.7/year since 1971. Total length of oil industry cross-country pipelines operating in Western Europe at the end of 1993 was 21,600 km, up from nearly 19,000 km in 1989. In all, 601 million cu m (3.8 billion bbl) of crude oil and refined products moved through the pipeline system. The paper briefly describes several of the accidents

Energy Technology Data Exchange (ETDEWEB)
NONE
1996-10-01
By agreement between Latvijas gaze and DONG (the Danish State Gas Company) the Sloka branch on the main gas pipeline Riga-Liepaja was selected for inspection. This pipeline is 30.5 km long and was constructed in 1966/67. The objective of the project has been, based on detailed inspection of relative short lengths of pipe, to determine the integrity of the pipeline and to give advice concerning the continued use as a high pressure transmission pipeline. A further objective has been to provide Latvijas gaze with a package of modern cathodic protection measuring instruments and the necessary know-how for using the instruments. The objectives have been met as follows: Based on a document review together with measurements and observations in the field and in the laboratory, the condition of approximately 10 km of pipeline has been evaluated; Recommendations are given in this report with the aim of extending the life of the pipeline; A cathodic protection instrument package was delivered and a two week training course was arranged in Latvia for Latvijas gaze`s staff covering the use of the instruments.

Full Text Available The reaction 22Ne(p, γ23Na is key to the NeNa cycle of stellar nucleogenesis, and better understanding of the 22Mg(p, γ23Al reaction is needed to understand the 22Na puzzle in ONe white dwarf novae. We aim to study these reactions using a multi-channel algebraic scattering (MCAS formalism for low-energy nucleon-nucleus scattering, recently expanded to investigate radiative capture. As a first step towards this goal, we here calculate the energy levels of the mass-23 (Ne, Mg, Na, Al nuclei. This is not only because the resonant structure of these nuclei are related to the astrophysical -rates of interest, but also because the interaction parameters determined for describing the energy levels are an integral part of the future calculation of the astrophysical reactions when using the MCAS scheme.

Pipeline monitoring using acoustic principal component analysis recognition with the Mel scale
International Nuclear Information System (INIS)
Wan, Chunfeng; Mita, Akira
2009-01-01
In modern cities, many important pipelines are laid underground. In order to prevent these lifeline infrastructures from accidental damage, monitoring systems are becoming indispensable. Third party activities were shown by recent reports to be a major cause of pipeline damage. Potential damage threat to the pipeline can be identified by detecting dangerous construction equipment nearby by studying the surrounding noise. Sound recognition technologies are used to identify them by their sounds, which can easily be captured by small sensors deployed along the pipelines. Pattern classification methods based on principal component analysis (PCA) were used to recognize the sounds from road cutters. In this paper, a Mel residual, i.e. the PCA residual in the Mel scale, is proposed to be the recognition feature. Determining if a captured sound belongs to a road cutter only requires checking how large its Mel residual is. Experiments were conducted and results showed that the proposed Mel-residual-based PCA recognition worked very well. The proposed Mel PCA residual recognition method will be very useful for pipeline monitoring systems to prevent accidental breakage and to ensure the safety of underground lifeline infrastructures

Reliability analysis of land pipelines for hydrocarbons transportation in Mexico
Energy Technology Data Exchange (ETDEWEB)
Leon, D.; Cortes, C. [Inst. Mexicano del Petroleo (Mexico)
2004-07-01
The reliability of a land pipeline operated by PEMEX in Mexico was estimated under a range of failure modes. Reliability and safety were evaluated in terms of the pipeline's internal pressure, bending, fracture toughness and its tension failure mode conditions. Loading conditions were applied individually, while bending and tension loads were applied in a combined fashion. The mechanical properties of the steel were also considered along with the degradation effect of internal corrosion resulting from the type of product being transported. A set of internal pressures and mechanical properties were generated randomly using Monte Carlo simulation. Commercial software was used to obtain the pipeline response under each modeled condition. The response analysis was based on the nonlinear finite element method involving a calculation of maximum stresses and stress concentration factors under conditions of corrosion and no corrosion. The margin between maximum stresses due to internal pressure, tension and bending was evaluated along with the margin between stress concentration factor and fracture initiation toughness. The study showed that internal pressure, stress concentration and tension-bending were the critical failure modes. It was suggested that more research should be conducted to improve the modeling of the deteriorating effects of corrosion and to adjust the probability distribution for fracture toughness and the length/depth defect ratio. The consideration of welding geometries along with features of marine pipelines and pipeline products would help to generalize the study to facilitate the creation of codes for the construction, design, inspection and maintenance of pipelines in Mexico. 7 refs., 1 tab., 14 figs.

2009-12-19
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)

Detecting features in pipelines containing flowing gas is difficult. This paper investigated a patented acoustic reflectometry technique for detecting defects in gas pipelines. The basic concept of this technique is to inject a pulse of sound into a pipeline and then measure the reflections produced while the signal travels along the length of the pipe. A modification in the internal section of the pipe will produce a reflection which, given with the speed of sound in the gas within the pipeline, provides the location of the feature. Laboratory tests on a 16m rigid PVC pipe and two field trials were undertaken to test this new method. The results showed that acoustic reflectometry can be used to identify features resulting from blockages and leakages. The field tests demonstrated that the method is capable of surveying both small and large diameter pipelines with lengths up to 10 km.

Full Text Available The analysis of next-generation sequence (NGS data is often a fragmented step-wise process. For example, multiple pieces of software are typically needed to map NGS reads, extract variant sites, and construct a DNA sequence matrix containing only single nucleotide polymorphisms (i.e., a SNP matrix for a set of individuals. The management and chaining of these software pieces and their outputs can often be a cumbersome and difficult task. Here, we present CFSAN SNP Pipeline, which combines into a single package the mapping of NGS reads to a reference genome with Bowtie2, processing of those mapping (BAM files using SAMtools, identification of variant sites using VarScan, and production of a SNP matrix using custom Python scripts. We also introduce a Python package (CFSAN SNP Mutator that when given a reference genome will generate variants of known position against which we validate our pipeline. We created 1,000 simulated Salmonella enterica sp. enterica Serovar Agona genomes at 100× and 20× coverage, each containing 500 SNPs, 20 single-base insertions and 20 single-base deletions. For the 100× dataset, the CFSAN SNP Pipeline recovered 98.9% of the introduced SNPs and had a false positive rate of 1.04 × 10−6; for the 20× dataset 98.8% of SNPs were recovered and the false positive rate was 8.34 × 10−7. Based on these results, CFSAN SNP Pipeline is a robust and accurate tool that it is among the first to combine into a single executable the myriad steps required to produce a SNP matrix from NGS data. Such a tool is useful to those working in an applied setting (e.g., food safety traceback investigations as well as for those interested in evolutionary questions.

Analysis of a buried pipeline at WWER-440/213 Paks NPP
International Nuclear Information System (INIS)
1999-01-01
According to regulations, all safety structures of a NPP must be designed to withstand loads induced by earthquakes. This applies to safety related underground piping systems. These structures are typically embedded in about 2-3 m of layered soil, and sometimes protected by concrete slabs resting on the ground surface. A rigorous solution for the dynamic response of such a structure would require accounting for nonlinear and three dimensional effects. A non-linear analysis is possible by using specialized computer codes and material models to account for non-linear behaviour of the soil. The aim of this paper was to reanalyze the pipeline of Paks NPP in order to demonstrate its dynamic behaviour interacting with the soil and the connected buildings as well as to determine the dynamic responses and the stresses in typical regions of the pipeline. To perform the numerical analysis a three dimensional finite element code (SSASSI/S) based on 'flexible volume method' was applied

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 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 %

This evaluation must be in line with requirements of our age, i.e. it has to assert such concept of which basis is not the `possible worst` but the `just happening wrong`. Solving these problems without application of computer resources is inconceivable in our time. The final purpose of the solution is the expert system and among the components of the expert system primarily the development of the knowledge base is needed. The paper demonstrates a possible structure of the knowledge base, furthermore its fundamental elements and their contents (defect types, evaluation possibilities of defects, categorisation of pipelines) and summaries the prospective advantages of its application.

The masses of the radioactive nuclei 22 Mg and 22 Na have been measured with the Canadian Penning trap on-line mass spectrometer to a precision of 3x10 -8 and 1x10 -8 , respectively. A Q EC value of 4124.39(73) keV for the superallowed β decay of 22 Mg is obtained from the difference of these two masses. With this precise Q value, the Ft value for this decay is determined with improved precision and is found to be consistent with the existing precision data set of superallowed Fermi emitters. This provides an important test of the isospin symmetry-breaking corrections. If the mass of 22 Mg determined here is used in the calibration of a recent 21 Na(p,γ) 22 Mg measurement, part of the discrepancy observed in that measurement is removed

Rectification of the water permeability in COS-7 cells at 22, 10 and 0°C.
Directory of Open Access Journals (Sweden)
Diana B Peckys
Full Text Available The osmotic and permeability parameters of a cell membrane are essential physico-chemical properties of a cell and particularly important with respect to cell volume changes and the regulation thereof. Here, we report the hydraulic conductivity, L(p, the non-osmotic volume, V(b, and the Arrhenius activation energy, E(a, of mammalian COS-7 cells. The ratio of V(b to the isotonic cell volume, V(c iso, was 0.29. E(a, the activation energy required for the permeation of water through the cell membrane, was 10,700, and 12,000 cal/mol under hyper- and hypotonic conditions, respectively. Average values for L(p were calculated from swell/shrink curves by using an integrated equation for L(p. The curves represented the volume changes of 358 individually measured cells, placed into solutions of nonpermeating solutes of 157 or 602 mOsm/kg (at 0, 10 or 22°C and imaged over time. L(p estimates for all six combinations of osmolality and temperature were calculated, resulting in values of 0.11, 0.21, and 0.10 µm/min/atm for exosmotic flow and 0.79, 1.73 and 1.87 µm/min/atm for endosmotic flow (at 0, 10 and 22°C, respectively. The unexpected finding of several fold higher L(p values for endosmotic flow indicates highly asymmetric membrane permeability for water in COS-7. This phenomenon is known as rectification and has mainly been reported for plant cell, but only rarely for animal cells. Although the mechanism underlying the strong rectification found in COS-7 cells is yet unknown, it is a phenomenon of biological interest and has important practical consequences, for instance, in the development of optimal cryopreservation.

Leak detection in gas pipeline by acoustic and signal processing - A review
Adnan, N. F.; Ghazali, M. F.; Amin, M. M.; Hamat, A. M. A.

The pipeline system is the most important part in media transport in order to deliver fluid to another station. The weak maintenance and poor safety will contribute to financial losses in term of fluid waste and environmental impacts. There are many classifications of techniques to make it easier to show their specific method and application. This paper's discussion about gas leak detection in pipeline system using acoustic method will be presented in this paper. The wave propagation in the pipeline is a key parameter in acoustic method when the leak occurs and the pressure balance of the pipe will generated by the friction between wall in the pipe. The signal processing is used to decompose the raw signal and show in time- frequency. Findings based on the acoustic method can be used for comparative study in the future. Acoustic signal and HHT is the best method to detect leak in gas pipelines. More experiments and simulation need to be carried out to get the fast result of leaking and estimation of their location.

Girth weld cracking is one of the main failure modes in oil and gas pipelines; girth weld cracking inspection has great economic and social significance for the intrinsic safety of pipelines. This paper introduces the typical girth weld defects of oil and gas pipelines and the common nondestructive testing methods, and systematically generalizes the progress in the studies on technical principles, signal analysis, defect sizing method and inspection reliability, etc., of magnetic flux leakage (MFL) inspection, liquid ultrasonic inspection, electromagnetic acoustic transducer (EMAT) inspection and remote field eddy current (RFDC) inspection for oil and gas pipeline girth weld defects. Additionally, it introduces the new technologies for composite ultrasonic, laser ultrasonic, and magnetostriction inspection, and provides reference for development and application of oil and gas pipeline girth weld defect in-line inspection technology.
