Abandoning pipelines working group regulatory issues  

Energy Technology Data Exchange (ETDEWEB)

The history of hydrocarbon development in Louisiana and off its coast is one of the interdependence of technological innovation, entrepreneurial risk-taking, resource management, judicial decisions, legislation, marketing, employee good will, infrastructure and support services, coupled with favorable geologic structures that made early exploration and development relatively easy. Mariners sailing off the coast of Louisiana and Texas in the 1600`s recorded one of the earliest known natural oil seeps. They shrugged it off as unimportant, as there was no market for the substance they witnessed. The seepage, however, provided a tiny clue to the vast storehouse of hydrocarbons trapped in the earth`s crust extending from the uplands, through Louisiana`s swamps and marshes, and into the subaqueous habitats of the Gulf of Mexico-the world`s ninth largest body of water. In all cases, each move into a new geographic province required considerable change in operation philosophy and in the science supporting the exploration and development activity. As technology changed, or was developed to meet the industry`s needs, new frontiers were explored. However, with time-as is the case with any nonrenewable resource-fields and wells lost their productive life. They had to be abandoned. In fact, the Minerals Management Service suggests that within the next 10 years the offshore industry will remove 150 platforms per year, or nearly half of the current number of production units. The industry will be asked to dispose of nearly one unit every 2.4 days. If this is the case, abandonment issues are going to continue to surface.

Abandoning wells working group  

Energy Technology Data Exchange (ETDEWEB)

The primary objective of this working group is to identify major technical, regulatory, and environmental issues that are relevant to the abandonment of offshore wellbores. Once the issues have been identified, the working group also has the objective of making recommendations or providing potential solutions for consideration. Areas for process improvement will be identified and {open_quotes}best practices{close_quotes} will be discussed and compared to {open_quotes}minimum standards.{close_quotes} The working group will primarily focus on wellbore abandonment in the Gulf of Mexico. However, workshop participants are encouraged to discuss international issues which may be relevant to wellbore abandonment practices in the Gulf of Mexico. The Abandoning Wells Group has identified several major areas for discussion that have concerns related to both operators and service companies performing wellbore abandonments in the Gulf of Mexico. The following broad topics were selected for the agenda: (1) MMS minimum requirements and state regulations. (2) Co-existence of best practices, new technology, and P & A economics. (3) Liability and environmental issues relating to wellbore abandonment.

Abandoned works program  

International Nuclear Information System (INIS)

Thousands of improperly abandoned or decommissioned oil and gas wells are threatening the purity of Ontario's source water. This presentation discussed an abandoned works program developed by the Ontario Ministry of Natural Resources. The abandoned works program was established in 2005 in order to plug old oil and gas wells. The program was designed to create a list of abandoned wells, develop a coherent policy, and formulate procurement and contracting protocols. Abandoned wells are defined as wells drilled prior to 1963 with no operator other than the current landowner. There are currently over 200 prioritized wells on the list. Twenty-six contracts have been issued for a total of 33 wells, and 19 wells have been plugged since the program's field operations began in 2006. However, the program is often challenged by the difficulties associated with determining where the wells are located. Many of the wells have been cut off and buried, and access is often dependent on weather conditions and road restrictions. There is also a shortage of contractors who have experience working with older wells. It was concluded that the program will expand by obtaining further funding and modifying its qualification criteria. tabs., figs

Pipeline abandonment - a discussion paper on technical and environmental issues  

International Nuclear Information System (INIS)

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

Pipeline abandonment: a discussion paper on technical and environmental issues  

International Nuclear Information System (INIS)

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

The development of the strategy and plan for the decommissioning and abandonment of 36'' offshore oil export pipelines  

Energy Technology Data Exchange (ETDEWEB)

The decommissioning and abandonment of platforms and pipelines are big challenges for the pipeline industry. This paper presents a review of the decommissioning and abandonment processes based on a study case, the Rabon Grande pipeline system. First, the applicable international codes, standards and regulations associated with the decommissioning of pipelines are discussed. Next, this paper presents a review of the decommissioning and abandonment options and considerations available for the study case. The Rabon Grande pipeline system, which was shut down and isolated in 1990 pending decommissioning, is used as an example of applying decommissioning and abandonment best practice and establishing a realistic scope of work. A decommissioning plan is developed in light of these previous studies, followed by an environmental impact assessment. It is found that contrary to what was done in the case of the Rabon Grande pipeline, when a pipeline is to be shutdown, the best practice methodology is to temporally or fully decommission the system as soon as possible.

Impacts of abandoned mine workings on aspects of urban development  

Energy Technology Data Exchange (ETDEWEB)

Man-made 'geohazards' (which can take the form of undermining, mine entrances, fault reactivation, mine-water rise, disposed wastes, derelict and contaminated land and subsurface civil engineering activities) are widely distributed in the United Kingdom, which has a history of mining activity dating back more than 3000 years. Many urban environments are located in regions where mining has occurred and abandonment has left a legacy of old workings and mine entries, many of which may still be uncharted and can be hazardous to development. The many aspects of mining and other human activity that give rise to potential geohazards are reviewed. Site investigation techniques appropriate to mining areas are discussed, with particular emphasis on rapid non-destructive (geophysical) survey methods. Some aspects of the current situation with regard to devaluation of properties (buildings) as a result of the availability of information on abandoned mining activities are discussed.

Working group 3: upstream pipelines: inspection, corrosion and integrity management  

Energy Technology Data Exchange (ETDEWEB)

The third topic investigated the latest challenges to upstream pipeline operation and the areas for improvement in upstream integrity in the pipeline industry. The first session of talks reported on the pipeline incident analysis conducted by the CAPP on several companies from 2006 to 2010 in order to identify best management practises and to drive improvement in pipeline integrity management. Reviews of primary failure statistics and failure frequency were conducted with respect to the various materials of pipes. A summary of changes to the CSA standard related to non-metallic pipes was also presented to complete this background overview of the upstream industry. The second session provided more information about these non-metallic pipes, focusing on construction and quality issues with large diameter HDPE pipelines. The third session discussed the ERW pipeline in relation to upstream industry. An integrity management panel discussion was carried out to close this third working group.

Computer Simulation of the Propagation of Heat in Abandoned Workings Insulated with Slurries and Mineral Substances  

Science.gov (United States)

In the paper the results of investigations aimed at further identification of the phenomena occurring in abandoned workings and connected with the flow of air-gas (methane, carbon dioxide, nitrogen, oxygen and carbon oxidation products) mixture with taking into consideration the impact of supplied mineral substances on the processes of self-heating of the coal left in goaves were presented. The known and successfully used method for the prevention of fires in abandoned workings is the technology of filling goaf with an ash-air mixture, which also raises the issue of the effective use of that mixture. The computer, i.e. digital simulation methods being developed and intended for the purpose of the process discussed here are a good complement of the use of that technology. A developed mathematical model describing the process of additional sealing of gob with wet slurry supplied with three pipelines is based on the balance of volume of the supplied mixture and contained in the body created in goaves. The form of that body was assessed on the basis of the observation results available in literature and the results of model investigations. The calculation examples carried out for the the longwall area and its goaf ventilated with the "U" system allow to state that the introduced modification of the mathematical model describing the flow of the mixture of air, gases, and wet slurry with consideration of the coal burning process in the fire source area was verified positively. The digital prognostic simulations have confirmed a vital impact of the wet slurry supplied into the goaf on the processes of coal burning and also the change of rate and volume flow rate of the air mixture in goaf. As a complement to the above it should be noted that such elements as the place of the slurry supply in comparison with the longwall inclination or fire source area location is of great importance for the effectiveness of the fire prevention used. The development of computer/ digital simulation methods requires further investigations of the model adopted in this study. Those investigations should be aimed at making credible the theoretical model of the mixture flow through porous medium and the supplied mineral material. Such investigations will allow to verify the body form based on the mixture parameters such as humidity, viscosity, and fluidity and depending on the properties of the porous medium. Further development of the modelling of the phenomena discussed in this paper should be based on the methods of use of the description of the flow of fluids and slurry on the basis of 3D models.

Child work and labour among orphaned and abandoned children in five low and middle income countries  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The care and protection of the estimated 143,000,000 orphaned and abandoned children (OAC worldwide is of great importance to global policy makers and child service providers in low and middle income countries (LMICs, yet little is known about rates of child labour among OAC, what child and caregiver characteristics predict child engagement in work and labour, or when such work infers with schooling. This study examines rates and correlates of child labour among OAC and associations of child labour with schooling in a cohort of OAC in 5 LMICs. Methods The Positive Outcomes for Orphans (POFO study employed a two-stage random sampling survey methodology to identify 1480 single and double orphans and children abandoned by both parents ages 6-12 living in family settings in five LMICs: Cambodia, Ethiopia, India, Kenya, and Tanzania. Regression models examined child and caregiver associations with: any work versus no work; and with working Results The majority of OAC (60.7% engaged in work during the past week, and of those who worked, 17.8% (10.5% of the total sample worked 28 or more hours. More than one-fifth (21.9%; 13% of the total sample met UNICEF's child labour definition. Female OAC and those in good health had increased odds of working. OAC living in rural areas, lower household wealth and caregivers not earning an income were associated with increased child labour. Child labour, but not working fewer than 28 hours per week, was associated with decreased school attendance. Conclusions One in seven OAC in this study were reported to be engaged in child labour. Policy makers and social service providers need to pay close attention to the demands being placed on female OAC, particularly in rural areas and poor households with limited income sources. Programs to promote OAC school attendance may need to focus on the needs of families as well as the OAC.

Living and working near pipelines : Landowner guide 2002  

International Nuclear Information System (INIS)

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

Corporate social responsibility along pipelines: communities and corporations working together  

Energy Technology Data Exchange (ETDEWEB)

In this paper we present GAIA's findings in three corporate social responsibility projects along pipelines owned by three Brazilian companies in gas, oil and mining sectors. The projects had as the main goal to improve the relationship with communities in the companies' direct influence areas. Clearly, the relationship with communities along pipelines is essential to prevent and reduce industrial hazards. The damage in pipelines due to agriculture, buildings, intentional perforations and traffic of heavy vehicles may cause fatal accidents, environmental and material losses. Such accidents have negative consequences with regard to economy, image and relationship with communities and environmental agencies. From communities' perspective, pipelines deteriorate their life quality due to risk of industrial hazards nearby their houses. The lack of proper information about the pipelines remarkably increases insecurity feelings and discourses against the companies among community leaders. The methodology developed by GAIA comprises companies' and communities' interests and encompasses nine stages. 1. Socio-environmental appraisal or inventory, mapping main risks, communities' needs and their leaders. 2. Communication plan, defining strategies, languages and communication vehicles for each stakeholder group. 3. Inter-institutional meetings to include other institutions in the program. 4. Launching seminar in partnership with local authorities, divulging companies' actions in the cities with pipelines. 5. Multiplier agents formation, enabling teachers, local leaders and government representatives to disseminate correct information about the pipelines such as their functioning, hazard prevention, maintenance actions, and restrictions of activities over the pipelines. 6. Formation on project management, enabling teachers, local leaders and government representatives to elaborate, fund raise and manage socio environmental projects aimed at improving communities' life quality. 7. Follow-up, supporting communities leaders during dissemination of information about pipelines, project fund-raising and implementation. 8. Creation and followup of companies' networks to support some of the projects elaborated by the communities. 9. Impact evaluation, measuring the results accomplished by the whole project after its realization. The overall process is monitored with management and quality tools such as PDCA and processes and results indicators. The elaboration of projects by communities' members, organizing their needs and requests, facilitates management decisions regarding private social investment. During the follow-up, GAIA supports the communities' fund-raising from several organizations, as well as creates networks of potential local supporters. Those initiatives tend to dilute the requests from communities to companies. Thus, companies foment communities' autonomy and citizenship, creating a situation in which both, companies and communities, are benefited. (author)

Deepwater pipeline intervention work with an acoustically controlled power module  

Energy Technology Data Exchange (ETDEWEB)

The stabilization of submarine pipeline free spans along uneven sea bottoms is performed conventionally using technologies such as gravel dumping, post trenching, and mattress installation. A new technology has been developed to support free spans along the 26-inch Transmed Gas Pipelines crossing the Sicily Channel in water depths ranging from 50 m to 510 m. This technology is based on the pipeline mechanical support Atlantis and its installation module Pegaso and was developed keeping requirements such as short installation time, system redundancy, operational flexibility, and simple interface with the support vessel in mind. The installation time reduction is achieved by automatic operational procedures that are controlled acoustically from the surface. Power is stored inside two dedicated battery packs placed on board pegaso; no umbilical cable is necessary, so that a vessel equipped with a normal crane is enough to launch and operate the system. Marine operations carried out in 1993 showed that a support can be installed in about 1 hour. In good weather conditions, three Atlantis were installed in 24 hours, including deck operations for recharging the battery packs. A total of 16 supports was installed along the 4th and 5th Transmed Gas Pipelines. The system has proved to be a cost-effective and flexible alternative to conventional technologies for free-span support, especially in deep waters. A cost/benefit analysis also shows the break-even point of the new technology vs. gravel dumping.

Degradation of the cast steel parts working in power plant pipelines  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: Purpose of this paper is to identify the influence of loading history and the processes of materialdegradation on the initiation of cracking and on durability under creep and fatigue conditions.Design/methodology/approach: The aim of the research was to identify the properties of the material of thefittings cut out of a start-up pipeline connecting two OP-140 boilers with turbines, as well as to identify thereasons of failure of these parts after 100000 hours of operation. Results of the investigations were the basisof predicting the lifetime of machine parts and components of devices subjected to complex mechanical andthermal influence. Numerical simulation of work conditions was also performed. Problem of life assessment ofthe pipelines is currently the object of interest of many research centers.Findings: Due to extreme conditions of the start-up pipeline operation, its T-connections are subject to quickwear, and their properties determine the operational reliability and safety of the whole pipeline. For the reasonit is necessary to verify the criteria of pipelines’ durability evaluation applied so far, based on the parameterscharacteristic of the creep process exclusively.Research limitations/implications: In the case discussed, i.e. a T-connection being a start-up pipeline part, thepresent criteria should be expanded with critical values describing fatigue/corrosion processes.Practical implications: The paper introduces the results of investigations of the 0.2C-1.2Cr-0.6Mo-0.3V caststeel used for parts of live steam pipelines working in power plants. Such parts include, e.g. T-connections.Originality/value: The paper show the possibilities of numerical models application.

The analysis of a work capacity of circular welds made for the Dsub(y)850 pipeline connection with high pressure vessels of heat resisting steel of the 15Kh1NMFA type has been carried out on the base of test results with small samples and real units. Welds were performed using the manual electric arc welding without the following heat treatment. It has been shown that residual stresses in such welds do not produce an essential effect on the resistance of weld metal and heat affected zone on the formation and developments of cracks

Effects of cessation of pumping at underground working on mine water quality at an abandoned coal mine in Korea  

Science.gov (United States)

Except several big mines, many coal mines were abandoned in the 1980s and 1990s and the pumping of mine water was either completely stopped or greatly reduced in Korea. After large-scale closure of the mines, water chemistry was changed in totally different in that metals such as Fe, Al and Mn, etc in mine water were highly concentrated. Although prediction and monitoring of the changes in the chemistry of mine drainage after the mine closure would be required for preparing the measures, there has been not any effort to monitor the effects of flooding of mine voids on the water chemistry in Korea. This work has been undertaken to assess the changes in water chemistry in the process of flooding of underground workings after cessation of pumping at the Dongwon coal mine located in Kwangwon province in Korea. The water level variations have been monitored by a CTD diver (Van Essen Instruments) installed in the shaft at the mine. The water column of about 200m, approximately one third of the whole shaft, was scanned for the evidence of geochemical stratification in the shaft using the MP troll 9500 (In Situ Inc.). In addition, samples were taken for the chemical analysis, and immediately measured for pH, oxidation reduction potential (ORP), dissolved oxygen (DO) and electrical conductivity (EC). After the cessation of pumping, mine water recovery in the shaft generally followed a linear trend with only minor deviations, although no data was available for one and half years immediately after the closure of the mine. The average rise velocity of the rebound was about 12 m per month during the monitoring of 15 months. Iron and sulfate contents considerably increased and reached to about 200 mg/L and over 1,260 mg/L, respectively, as the level of mine water rose. However, Al and Mn contents remained relatively constant during the monitoring period, showing irrelevance to the water recovery. The geochemical stratification of the water column of 200m high was not observed and pH and EC were relatively constant, with the measured values of around 6.5 and 2,050 ?S/cm, respectively. The water column of the shaft was in anoxic condition because the value of DO was found lower than 1 mg/L.

Carbon Dioxide Corrosion: : Modelling and Experimental Work Applied to Natural Gas Pipelines  

DEFF Research Database (Denmark)

CO2 corrosion is a general problem in the industry and it is expensive. The focus of this study is an oil gas production related problem. CO2 corrosion is observed in offshore natural gas transportation pipelines. A general overview of the problem is presented in chapter 1. The chemical system consists mainly of CO2-Na2CO3-NaHCO3-MEG-H2O. Sodium is injected in the pipelines as NaOH in order to pH-stabilize the pipeline to avoid corrosion and MEG is injected in order to prevent gas hydrates. There are a great number of models available in the literature which may predict CO2 corrosion. These models are not very accurate and assume ideality in the main part of the equation. This thesis deals with aspect of improving the models to account for the non-ideality. A general overview and extension of the theory behind electrochemical corrosion is presented in Chapter 2 to 4. The theory deals with the basic thermodynamics of electrolytes in chapter 2, the extension and general description of electrolyte mass transport in chapter 3, and the electrochemical kinetics of corrosion in chapter 4. A literature overview of CO2 corrosion is shown in chapter 5 and possible extensions of the models are discussed. A list of literature cites is given in chapter 6. The literature review in chapter 5 shows how FeCO3 plays a main part in the protection of steel. Especially the solubility of FeCO3 is an important factor. Chapter 7 discusses and validates the thermodynamic properties of FeCO3. The study shows that there is a discrepancy in the properties of FeCO3. Sets of consistent thermodynamic properties of FeCO3 are given. A mixed solvent electrolyte model is regressed in chapter 8 for the CO2-Na2CO3-NaHCO3-MEG-H2O system. Parameters of the extended UNIQUAC model is fitted to literature data of VLE, SLE, heat excess and validated against heat capacity data. The model is also fitted to experimental data produced and shown in chapter 8 for SLE in the Na2CO3-NaHCO3-MEG-H2O system. The application of the above model is shown in chapter9. Here the thermodynamic correction factors are calculated. These show how the diffusion process in CO2 corrosion models deviate from the ideal case. Conclusion and suggestion for future work are presented in chapter 10 and 11.

Alaska Highway Pipeline Project and First Nations : Linkages : Working Paper No. 7.6  

International Nuclear Information System (INIS)

The construction of the proposed Alaska Highway Pipeline Project (AHPP) will bring several employment opportunities for Yukon First Nations citizens. This paper presented some recommendations to maximize these employment benefits. The AHPP will cross the territory of 8 of the 14 Yukon First Nations. The current land selections through the Foothills route indicate that 202 km of the 832 km long pipeline will end up on First Nations land. The six channels of economic impact for First Nations include: (1) employment of First Nations citizens on pipeline construction and operation, (2) First Nation-owned business on pipeline construction, (3) employment of First Nations citizens in other Yukon businesses, (4) taxation, (5) availability of natural gas, and (6) additional services and infrastructure that will be incurred. 2 tabs., 1 fig

Abandoned vehicles  

CERN Multimedia

The services in charge of managing the CERN site have recently noted an increase in the number of abandoned vehicles. This poses a risk from the point of view of safety and security and, on the eve of several important events in honour of CERN's fiftieth anniversary, is detrimental to the Organization's image. Owners of vehicles that have been left immobile for some time on the CERN site, including on the external car park by the flags, are therefore invited to contact the Reception and Access Control Service (service-parking-longterm@cern.ch) before 1st October 2004 and, where appropriate, move their vehicle to a designated long-term parking area. After this date, any vehicle whose owner has failed to respond to this request and which is without a number plate, has been stationary for several weeks or is out of service, may be impounded at the owner's risk and expense.

National impact of Alaska Highway Pipeline Project : Working Paper No. 6.1.1  

International Nuclear Information System (INIS)

This report examined the economic impacts of the Alaska Highway Pipeline Project (AHPP) for Canada. The proposed project will impact the economy through construction of the pipeline as well as through export of natural gas transmission services. Interest in Alaskan North Slope natural gas has been renewed because of the following 3 main factors: (1) the US energy policy is promoting cleaner burning fuels, particularly for power generation, (2) the recent winter price shocks for both oil and natural gas, and (3) the US effort to protect and guarantee energy supplies. The impact of northern gas and pipeline development was assessed with reference to the impact that spending will have on the Canadian economy. A standard macroeconomic impact model is employed, first by preparing a base case forecast of the economy, assuming that the project does not occur. Secondly, an impact case forecast of the economy was prepared assuming the pipeline is developed and operated. The third step of the procedure involved a comparison of impacts of the first and second procedures. The report presented direct, indirect and induced impacts. The Informetrica Model (TIM) of the national economy is used to obtain behavioural underpinning to the analysis. The model is very detailed in industry terms and links demands on the economy, output and employment of many industries, as well as costs and prices of industries and commodities in a consistent framework. Both the upside and the downside of tork. Both the upside and the downside of the proposed pipeline were presented. 16 figs

Alaska Highway Pipeline Project and the environment : Working Paper No. 7.2.8  

International Nuclear Information System (INIS)

This paper presented a brief overview of the environmental impacts that may occur if the Alaska Highway Pipeline Project (AHPP) goes ahead as planned. It presents the position of local environmental groups, including the Yukon Conservation Society and the Yukon chapter of the Canadian Parks and Wilderness Society. Both have signed a statement which calls for a system of protected areas to be completed, as well as detailed regional land use plans before construction begins. They also call for a strict environmental assessment process that would include a no-go option and which would examine the potential cumulative effects of the project. This paper presented the general environmental concerns and impacts of construction, with reference to habitat disruption, Southern Lakes Caribou winter habitat, stream crossings, and erosion. It also included several site specific impacts along the existing Foothills pipeline segment that are of particular environmental concern for Kluane Lake, Sheep Mountain, Slims River and Ibex Valley. There are minimal environmental concerns regarding the operation of the pipeline. One potential impact is on air quality near compressor stations through the creation of ice fog in the winter. Noise pollution is another possible problem if inadequate muffler systems are used. Also, the effect of maintaining a wider transportation corridor is not yet known. The proposed construction will likely accelerate oil and gas development in the Yukon which wi and gas development in the Yukon which will have large and long-term impacts. One of the arguments in favour of the natural gas pipeline, is its potential to reduce pollution of SOx, NOx and VOCs on a continental scale by allowing substitution of clean burning natural gas instead of coal or diesel fuels. In terms of the impact on global warming, the pipeline can only reduce net emissions of greenhouse gases if the additional gas does not translate into higher net energy use. One additional concern for the Yukon is how emissions will be charged or credited. For example, will the Yukon be charged for compressor station emissions even if the gas is Alaskan? 3 refs

Proceedings of the 11. Banff 2011 pipeline workshop: managing pipeline integrity  

Energy Technology Data Exchange (ETDEWEB)

Twelve working groups provided an interactive forum where the management of the integrity, the risk, and the safety of pipeline infrastructures were discussed. Several presentations from operators, regulators and vendors provided the material necessary to initiate debates and information sharing between the participants. This conference brought together speakers from the international and domestic corrosion community to present technical papers and participate in a panel discussion. First they focused on reporting the state-of-the-art technologies and past experience related to the design, construction, operation, testing, maintenance and abandonment of pipelines. The current standards and management processes were examined using in-field examples. Several technology exchange groups were created to further discuss, and foster the development of, new technologies in order to develop guidelines for consideration as standard practices. All 12 working groups sessions have been catalogued separately for inclusion in this database.

Provincial impacts of Alaska Highway Pipeline Project : Working Paper No. 7.1.1  

International Nuclear Information System (INIS)

The impact that the construction and operation of the proposed Alaska Highway Pipeline Project will have on the Canadian economy was examined. Part 2 of this report presents a series of assumptions where the changes to the economy were explained with reference to the cost of developing facilities, revenues earned by their operations and other determinants that affect jurisdictional and sectorial impacts. The third part of the report presents the implications for the Northwest Territories/Yukon, British Columbia and Alberta since they are the regions that will be directly impacted by the AHPP. The significance of the development that extend beyond the immediately impacted regions was also assessed. For the impact analysis procedure, a base case forecast of the economy was prepared, assuming the project does not go ahead. This was followed by an impact case forecast of the economy in which the pipeline is developed and operated. Direct, indirect and induced effects were described. Two impact cases were considered for both national and regional studies. For the first case, all changes in government balances from increased revenues were assumed to go directly into debt reduction or acquisition of financial assets. For the second case, the governments recycle the increased revenue using a lower employment insurance contribution rate, and keeping federal business tax revenue and federal personal income tax revenue equal to the base case. The general effect of the second scecase. The general effect of the second scenario is to increase the induced effects by increasing disposable income through lower tax rates. The report examined assumptions in the construction phase with reference to capital costs and construction employment. It also examined assumptions in the operational phase with reference to transportation services and operations employment. 7 tabs., 12 figs

Waste management plan for pipeline construction works: basic guideline for its preparation  

Energy Technology Data Exchange (ETDEWEB)

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

Care of the abandoned child.  

Science.gov (United States)

Care of abandoned children in India is discussed in terms of reasons for abandonment, the physical condition of the children, and legal categories. The options available currently are the cottage system, sponsorship programs, foster care, or adoption. Child-care and rehabilitation that may be necessary is specified as is the importance of maintaining records. The gaps in child-care are exposed. The role of nongovernmental organization (NGOs) and new legislation in closing the gaps is presented. Abandonment is usually a direct result of poverty, but it can also be caused by mental or physical handicaps or illegitimacy. The numbers of abandoned children may reach 2 million. 40-60% of abandoned infants die during monsoons and summers. The legal categories are privately abandoned, children on remand, or court-committed children. The cottage system emphasizes deinstitutionalization, but there remains a great demand for care. Sponsorship aims to strengthen the family unit to prevent abandonment. Foster care provides an alternative family substitute, but is known only theoretically. Childcare may involve instant hospitalization, care is an institution, or foster care with a suitable family. Nursery care requires discipline in hygiene, sanitation, maintenance of individual medical records, and a general cheerful atmosphere. Records are important for the child in later life and for adoption. Rehabilitation is a sociolegal process which must be done properly or it can jeopardize a child's future security. Despite the Supreme Court guidelines of 1984, there is no uniform system of adoption practices, and the child's interests are overlooked when adoptions are promoted. NGOs play an important role in making social welfare programs work. However their efforts are of limited help without government support and legislation. There is a lack of proper legislation which is outside the control of political and religious interests; e.g., Hindu law only permits adoption of one child of each sex. Malpractice exists because of the lack of uniform legislation and implementation, and restrictive and delaying tactics are just as harmful to the child. Trafficking in children to foreigners is still profitable. Suggestions include uniform and appropriate legislation, collaborative effort of NGOs and government-endorsed implementation, promotion of innovative and preventive measures to reduce abandonment, and development of an extensive program to provide safeguards against the exploitation of women.

Abandoned Texas oil fields  

Energy Technology Data Exchange (ETDEWEB)

Data for Texas abandoned oil fields were primarily derived from two sources: (1) Texas Railroad Commission (TRRC), and (2) Dwight's ENERGYDATA. For purposes of this report, abandoned oil fields are defined as those fields that had no production during 1977. The TRRC OILMASTER computer tapes were used to identify these abandoned oil fields. The tapes also provided data on formation depth, gravity of oil production, location (both district and county), discovery date, and the cumulative production of the field since its discovery. In all, the computer tapes identified 9211 abandoned fields, most of which had less than 250,000 barrel cumulative production. This report focuses on the 676 abandoned onshore Texas oil fields that had cumulative production of over 250,000 barrels. The Dwight's ENERGYDATA computer tapes provided production histories for approximately two-thirds of the larger fields abandoned in 1966 and thereafter. Fields which ceased production prior to 1966 will show no production history nor abandonment date in this report. The Department of Energy hopes the general availability of these data will catalyze the private sector recovery of this unproduced resource.

Abandonment of atomic energy  

International Nuclear Information System (INIS)

An exchange of open letters between an antagonist and a protagonist of atomic energy power generation. Following the reactor accident at Chernobyl, the first correspondent (H. Hubacher) suggests that energy conservation, together with additional emphasis on renewable energy sources, should permit abandonment of nuclear power without additional costs. He points to the costs of nuclear waste disposal, and to the statistical risks of future accidents. The other correspondent (M. Kohn) suggests that abandonment of nuclear power generation is proposed by special interests groups, and that alternative power generation from fossil fuels also poses dangers. He emphasises the enormous costs of abandoning nuclear energy. (G.M.E.)

Inter provincial input-output analysis of the Alaska Highway Pipeline Project : Working Paper No. 7.2.1  

International Nuclear Information System (INIS)

The economic impact of the Alaska Highway Pipeline Project (AHPP) was examined using an inter provincial input-output model (IPIO) consisting of 10 provincial input-output matrix sets and 2 territorial IO matrix sets which were then interconnected through inter provincial trade flow. Changes in any province, industry or commodity will impact on other provinces, industries and commodities. The AHPP will cause investment and production of pipeline services to increase. Investment will require additional products from the economy that can come from domestic industries or imported from foreign markets. The purchase and installation of pipeline and any preparation costs would be associated with non-residential structure investment. The report refers to both machinery and equipment capital expenditures, and pipeline cost-of-service. Direct, indirect and induced effects were also examined. The construction phase impact for the Yukon segment of the AHPP will be $2,138 million from structures investment, and $1,231 million from machinery and equipment investment.

Environmental audit guidelines for pipelines  

International Nuclear Information System (INIS)

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

Design and stabilization works of the km 767 slope of Bolivia-Brazil gas pipeline; Projeto e obra de estabilizacao do talude do km 767 do gasoduto Bolivia-Brasil  

Energy Technology Data Exchange (ETDEWEB)

The Bolivia-Brazil Natural Gas Pipeline starts at Santa Cruz de La Sierra city, in Bolivia, and goes until Canoas City (RS) in Brazil, with a total extent of 3,150 km. The pipeline crosses in the 2,593 km established in Brazilian soil, the most diverse types of geology and geomorphology. Along the line, the right-of-way (ROW) also crosses a lot of roads, railways, rivers and lakes. During a routine inspection (foot patrol), signs of instability were detected at an embankment slope of a highway of the Santa Catarina state, at the pipeline crossing. An eventual failure of this slope could put the pipeline at risk. The aim of this paper is to present the aspects of the stabilizations phases, since field investigation, design, works, instrumentation, until monitoring. Emphasis is given to the design criteria to pipeline safety. The solution adopted is composite by soil nailing, a changing of slope inclination and superficial drainage system. (author)

Planning for abandonment  

International Nuclear Information System (INIS)

The objective of this series of papers is to address the pressing issues surrounding the concept of abandonment of Northern North Sea offshore production facilities and structural steel jackets. For many operators there is a notional idea that when you are finished with an offshore production facility and structural steel jackets, they merely sail away over the horizon never to be seen or heard of again, but the real world dictates otherwise. For those that operate today in the Northern North Sea there is perhaps a uniqueness in character related to the design, fabrication, installation and operation of these Northern North Sea offshore production facilities. Approaching now for many the reality of abandonment, removal and disposal of these facilities, the oil and gas industries must now also recognize that unique methodology requires to be developed for implementation to overcome this daunting task of abandonment. Innovative and lateral thinking being employed by those companies and individuals who have risen to take up the challenge to achieve the goals and objectives, developing the ultimate solution to this enormous problem facing the oil and gas industry today. Many common aspects and activities exist for operators to undertake jointly during the planning, engineering and the various implementation stages for this ultimate episode in field life

Preliminary characterization of abandoned septic tank systems. Volume 1  

International Nuclear Information System (INIS)

This report documents the activities and findings of the Phase I Preliminary Characterization of Abandoned Septic Tank Systems. The purpose of the preliminary characterization activity was to investigate the Tiger Team abandoned septic systems (tanks and associated leachfields) for the purpose of identifying waste streams for closure at a later date. The work performed was not to fully characterize or remediate the sites. The abandoned systems potentially received wastes or effluent from buildings which could have discharged non-domestic, petroleum hydrocarbons, hazardous, radioactive and/or mixed wastes. A total of 20 sites were investigated for the preliminary characterization of identified abandoned septic systems. Of the 20 sites, 19 were located and characterized through samples collected from each tank(s) and, where applicable, associated leachfields. The abandoned septic tank systems are located in Areas 5, 12, 15, 25, and 26 on the Nevada Test Site

OPGN approach to SSC abandonment  

International Nuclear Information System (INIS)

Abandonment of equipment is a fact of life for an aging nuclear station. Whether this equipment is no longer needed, cannot be removed during a modification, remains in place due to economic considerations or other reasons, the continued existence of abandoned equipment poses design, maintenance and operational challenges for the remaining life of the station. Operational Experience has shown a number of incidents when improperly abandoned equipment or system has resulted in significant safety events. This presentation cites some real life examples to highlight the importance of properly abandoning equipment and discusses a proposed methodology.

Abandoned luggage detection using a finite state automaton in surveillance video  

Science.gov (United States)

We present an abandoned luggage detection architecture that consists of an intelligent surveillance system for public places. Detection of abandoned luggage is necessary because unattended or abandoned luggage can be used as a means of terrorist attack, especially for bombs. Our proposed system relies on three modules: moving object detection, object tracking and classification, and event recognition. We focus on abandoned luggage detection. To recognize an abandoned luggage event, we constructed the finite state automaton (FSA), in which each FSA state represents a certain luggage status. The proposed algorithm shows good performance in a real-world environment and also works at real-time speed.

Development of guidelines for parallel pipelines  

Energy Technology Data Exchange (ETDEWEB)

Increasing demand for natural gas in many locations means there is often a need to increase the capacity of existing and future gas transmission pipeline networks. Sometimes the operating pressure can be increased, but sometimes there is no alternative but to lay new pipelines, often along the same route. If one pipeline fails in this situation, a second parallel pipeline may also fail as a result. However there is also increasing pressure on the use of land and therefore the minimum separations with which pipelines may be laid need to be considered. This paper describes work carried out as a collaborative project supported by gas transmission pipeline operators to provide guidance on the likelihood of failure of a pipeline, for a range of different conditions, following failure of an adjacent pipeline. A framework has been developed identifying sequence of events and work has been carried out including large scale experiments and CFD modelling.

Highly tensioned suspended pipelines  

Energy Technology Data Exchange (ETDEWEB)

The feasibility of using highly tensioned suspended pipelines (HTSPs) for above ground, cross-country pipelines in Arctic regions was discussed. The concept was first considered in 1996 by ARCO Technology and Operations Support (ARCO TOS). This paper presents the results of three years of development work including analytical modeling, pipeline code compliance, conceptual design of components and construction studies. The basis for HTSPs is similar to high voltage power lines with similar construction methods and support towers. The main difference is that pipelines are larger in diameter and are supported against out-of-plane wind loads. Another difference of HTSPs from conventional above ground pipes is that the weight of the pipe is carried mostly by axial tension force in the pipe instead of by beam action. HTSPs can therefore span several hundred feet. They have the potential to reduce costs significantly compared to conventional pipelines and can have fewer environmental impacts. However, because they are radically different, this paper outlined some of the criteria for their design, analysis, construction, monitoring, operation and maintenance that should be considered. It was concluded that the development of a prototype would be an important step toward the eventual implementation of the HTSP system. 21 refs., 9 figs.

INTERNAL REPAIR OF PIPELINES  

Energy Technology Data Exchange (ETDEWEB)

The two broad categories of fiber-reinforced composite liner repair and deposited weld metal repair technologies were reviewed and evaluated for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Principal conclusions from a survey of natural gas transmission industry pipeline operators can be summarized in terms of the following performance requirements for internal repair: (1) Use of internal repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling when a new bore must be created to solve a leak or other problem. (3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) The most common size range for 80% to 90% of operators surveyed is 508 mm (20 in.) to 762 mm (30 in.), with 95% using 558.8 mm (22 in.) pipe. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without liners, indicating that this type of liner is only marginally effective at restoring the pressure containing capabilities of pipelines. Failure pressures for larger diameter pipe repaired with a semi-circular patch of carbon fiber-reinforced composite lines were also marginally greater than that of a pipe section with un-repaired simulated damage without a liner. These results indicate that fiber reinforced composite liners have the potential to increase the burst pressure of pipe sections with external damage Carbon fiber based liners are viewed as more promising than glass fiber based liners because of the potential for more closely matching the mechanical properties of steel. Pipe repaired with weld deposition failed at pressures lower than that of un-repaired pipe in both the virgin and damaged conditions, indicating that this repair technology is less effective at restoring the pressure containing capability of pipe than a carbon fiber-reinforced liner repair. Physical testing indicates that carbon fiber-reinforced liner repair is the most promising technology evaluated to-date. In lieu of a field installation on an abandoned pipeline, a preliminary nondestructive testing protocol is being developed to determine the success or failure of the fiber-reinforced liner pipeline repairs. Optimization and validation activities for carbon-fiber repair methods are ongoing.

Vale do Aco pipeline: pipeline natural gas implementation in ArcelorMittal Monlevade steel work; Gasoduto Vale do Aco: implantacao do gas natural via gasoduto na ArcelorMittal Monlevade  

Energy Technology Data Exchange (ETDEWEB)

Since September 2010, ArcelorMittal Monlevade has gained flexibility and an important opportunity to reduce the cost of its energy mix due to the arrival of the Natural Gas (NG) via Steel Valley Pipeline. The proposal of the project included the substitution of the Liquefied Petroleum Gas (LPG), Fuel Oil and Compressed Natural Gas for natural gas via pipeline. To support the investment decision, in addition to domestic economic and technical aspects, the macro economic environment concerning the NG was also taken into account. This paper shows the analysis for adjustment of internal equipment, the structure of the contract, the conceptual project of the gas distribution built inside the main events, the gains achieved, the alternatives for the acquisition of NG and operational flexibility of ArcelorMittal Monlevade in case of interruption of supply of natural gas.

Pipeline regulation in Canada: a guide for landowners and the public  

Energy Technology Data Exchange (ETDEWEB)

In Canada, the construction, operation and abandonment of a pipeline is highly regulated by the National Energy Board (NEB). The NEB regulates pipelines, energy development and energy trade at international and interprovincial levels, in the public interest. This document aims to provide landowners and the public with a better understanding of pipeline regulation in Canada and may be useful to companies, environmental groups or anyone interested in knowing about pipeline regulation. This guide explains the regulatory process that companies must follow to be allowed by the NEB to build a pipeline.

Underground gas storage in abandoned salt mine  

Energy Technology Data Exchange (ETDEWEB)

The possibility of using an abandoned salt mine for underground gas storage has been investigated. The preparation of a conceptual design and its approval are described. The design assumed that each of the two mine shafts be sealed with a double concrete plug and a shaft above the plug be filled with a fluid of a suitable density. The connection between underground workings and surface gas installation should involve two exploitation boreholes. Advantageous location and well-developed infrastructure mean that there should be a fast return of investment outlays for the project. 2 figs.

Cleaning-up abandoned uranium mines in Saskatchewan's North  

International Nuclear Information System (INIS)

Thirty-six now-abandoned uranium mine and mill sites were developed and operated on or near Lake Athabasca, in Northern Saskatchewan, Canada, from approximately 1957 through 1964. During their operating lifetimes these mines produced large quantities of ore and tailings. After closure in the 1960's, these mine and mill sites were abandoned with little remediation and no reclamation being done. The governments of Canada and Saskatchewan are now funding the cleanup of these abandoned northern uranium mine and mill sites and have contracted the management of the project to the Saskatchewan Research Council (SRC). The clean-up activity is underway, with work at many of the smaller sites largely completed, work at the Gunnar site well underway, and a beginning made at the Lorado site. This lecture presents an overview of these operations. (author)

Upstream pipelines : inspection, corrosion and integrity management  

Energy Technology Data Exchange (ETDEWEB)

Accurate inspection techniques are needed to ensure the integrity of pipelines. This working group discussed methods of reducing pipeline failures for a variety of pipes. A summary of recent pipeline performance statistics was presented, as well as details of third party damage and fiberglass pipe failures. A batch inhibitor joint industry project was described. The session demonstrated that integrity program need to be developed at the field-level as well as at the upper management level. Fiberglass pipeline failures are significant problem for pipeline operators. Corrosion monitoring, pigging and specific budgets are needed in order to ensure the successful management of pipeline integrity. New software developed to predict pipeline corrosion rates was discussed, and methods of determining mole fractions and flow regimes were presented. The sessions included updates from regulators and standards agencies as well as discussions of best practices, regulations, codes and standards related to pipeline integrity. The working group was divided into 4 sessions: (1) updates since 2007 with input from the Canadian Association of Petroleum Producers (CAPP) and the Upstream Pipeline Integrity Management Association (UPIMA); (2) integrity of non-metallic pipelines; (3) upstream pipeline integrity issues; and (4) hot topics. tabs., figs.

Northern pipelines : challenges and needs  

Energy Technology Data Exchange (ETDEWEB)

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.

Who abandons embryos after IVF?  

LENUS (Irish Health Repository)

This investigation describes features of in vitro fertilisation (IVF) patients who never returned to claim their embryos following cryopreservation. Frozen embryo data were reviewed to establish communication patterns between patient and clinic; embryos were considered abandoned when 1) an IVF patient with frozen embryo\\/s stored at our facility failed to make contact with our clinic for > 2 yrs and 2) the patient could not be located after a multi-modal outreach effort was undertaken. For these patients, telephone numbers had been disconnected and no forwarding address was available. Patient, spouse and emergency family contact\\/s all escaped detection efforts despite an exhaustive public database search including death records and Internet directory portals. From 3244 IVF cycles completed from 2000 to 2008, > or = 1 embryo was frozen in 1159 cases (35.7%). Those without correspondence for > 2 yrs accounted for 292 (25.2%) patients with frozen embryos; 281 were contacted by methods including registered (signature involving abandoned embryos did not differ substantially from other patients. The goal of having a baby was achieved by 10\\/11 patients either by spontaneous conception, adoption or IVF. One patient moved away with conception status unconfirmed. The overall rate of embryo abandonment was 11\\/1159 (< 1%) in this IVF population. Pre-IVF counselling minimises, but does not totally eliminate, the problem of abandoned embryos. As the number of abandoned embryos from IVF accumulates, their fate urgently requires clarification. We propose that clinicians develop a policy consistent with relevant Irish Constitutional provisions to address this medical dilemma.

PIPELINES AS COMMUNICATION NETWORK LINKS  

Energy Technology Data Exchange (ETDEWEB)

This report presents the results of an investigation into two methods of using the natural gas pipeline as a communication medium. The work addressed the need to develop secure system monitoring and control techniques between the field and control centers and to robotic devices in the pipeline. In the first method, the pipeline was treated as a microwave waveguide. In the second method, the pipe was treated as a leaky feeder or a multi-ground neutral and the signal was directly injected onto the metal pipe. These methods were tested on existing pipeline loops at UMR and Batelle. The results reported in this report indicate the feasibility of both methods. In addition, a few suitable communication link protocols for this network were analyzed.

International Nuclear Information System (INIS)

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

Localized Detection of Abandoned Luggage  

Directory of Open Access Journals (Sweden)

Full Text Available Abandoned luggage represents a potential threat to public safety. Identifying objects as luggage, identifying the owners of such objects, and identifying whether owners have left luggage behind are the three main problems requiring solution. This paper proposes two techniques which are “foreground-mask sampling” to detect luggage with arbitrary appearance and “selective tracking” to locate and to track owners based solely on looking only at the neighborhood of the luggage. Experimental results demonstrate that once an owner abandons luggage and leaves the scene, the alarm fires within few seconds. The average processing speed of the approach is 17.37 frames per second, which is sufficient for real world applications.

Crude oil pipeline expansion summary  

International Nuclear Information System (INIS)

The Canadian Association of Petroleum Producers has been working with producers to address issues associated with the development of new pipeline capacity from western Canada. This document presents an assessment of the need for additional oil pipeline capacity given the changing mix of crude oil types and forecasted supply growth. It is of particular interest to crude oil producers and contributes to current available information for market participants. While detailed, the underlying analysis does not account for all the factors that may come into play when individual market participants make choices about which expansions they may support. The key focus is on the importance of timely expansion. It was emphasized that if pipeline expansions lags the crude supply growth, then the consequences would be both significant and unacceptable. Obstacles to timely expansion are also discussed. The report reviews the production and supply forecasts, the existing crude oil pipeline infrastructure, opportunities for new market development, requirements for new pipeline capacity and tolling options for pipeline development. tabs., figs., 1 appendix

The LOFAR Pulsar Data Pipeline  

Science.gov (United States)

The LOw Frequency ARray (LOFAR) for radio astronomy is being built in the Netherlands by ASTRON, with extensions throughout Europe. LOFAR operates at radio frequencies below 250 MHz. The project is an interferometric array of radio antennas grouped into stations that are distributed over an area of hundreds of kilometers. LOFAR will revolutionise low-frequency radio astronomy. Transient radio phenomena and pulsars are one of six LOFAR Key Science Projects (KSPs). As part of the Transients KSP, the Pulsar Working Group has been developing the LOFAR Pulsar Data Pipeline to both study known pulsars as well as search for new ones. The pipeline is being developed for the Blue Gene/P (BG/P) supercomputer and a large Linux cluster in order to utilize enormous amounts of computation capabilities (˜ 50 Tflops) and data streams of up to 23TB/hour. The LOFAR pipeline output will be using the Hierarchical Data Format 5 (HDF5) to efficiently store large amounts of numerical data, and to manage complex data encompassing a variety of data types, across distributed storage and processing architectures. We present the LOFAR Pulsar Data Pipeline overview, the pulsar beam-formed data format, the status of the pipeline processing as well as our future plans for developing additional transient pipelines.

optimization for trenchless reconstruction of pipelines  

Directory of Open Access Journals (Sweden)

Full Text Available Today the technologies of trenchless reconstruction of pipelines are becoming and more widely used in Russia and abroad. One of the most perspective is methods is shock-free destruction of the old pipeline being replaced with the help of hydraulic installations with working mechanism representing a cutting unit with knife disks and a conic expander. A construction of a working mechanism, which allows making trenchless reconstruction of pipelines of different diameters, is optimized and patented and its developmental prototype is manufactured. The dependence of pipeline cutting force from knifes obtusion of the working mechanisms. The cutting force of old steel pipelines with obtuse knife increases proportional to the value of its obtusion. Two stands for endurance tests of the knifes in laboratory environment are offered and patented.

Abandonment (field decommissioning): The legal requirements  

International Nuclear Information System (INIS)

The main areas to be considered in relation to the abandonment of offshore installations are: (1) the legal requirements to be imposed in relation to abandonment, this will include consideration of English, Norwegian and Dutch law as well as international law; (2) how licensees may protect themselves against joint and several liability for performance of their legal obligations in relation to abandonment by the provision of security; and (3) consideration of practical examples of abandonment such as the abandonment of the Piper Alpha platform on the UK continental shelf and the K13-D platform on the Dutch continental shelf. This paper considers only abandonment of offshore installations as very different considerations apply onshore and applies only to Europe, though the international treaties will also apply elsewhere

Global Sea Level Stabilization-Sand Dune Fixation: A Solar-powered Sahara Seawater Textile Pipeline  

CERN Document Server

Could anthropogenic saturation with pumped seawater of the porous ground of active sand dune fields in major deserts (e.g., the westernmost Sahara) cause a beneficial reduction of global sea level? Seawater extraction from the ocean, and its deposition on deserted sand dune fields in Mauritania and elsewhere via a Solar-powered Seawater Textile Pipeline (SSTP) can thwart the postulated future global sea level. Thus, Macro-engineering offers an additional cure for anticipated coastal change, driven by global sea level rise, that could supplement, or substitute for (1) stabilizing the shoreline with costly defensive public works (armoring macroprojects) and (2) permanent retreat from the existing shoreline (real and capital property abandonment). We propose Macro-engineering use tactical technologies that sculpt and vegetate barren near-coast sand dune fields with seawater, seawater that would otherwise, as commonly postulated, enlarge Earth seascape area! Our Macro-engineering speculation blends eremology with...

Drake F-76 in-situ abandonment of a high Arctic offshore completion and facilities  

International Nuclear Information System (INIS)

Technical assessment of the abandonment operations of an offshore natural gas well drilled from an ice platform in 55 m of water off the Northwest Territories of Canada was discussed. The well was drilled offshore Melville Island in 1979 as a prototype gas producer, using a subsea production tree and subsea pipeline bundle to shore. The project was suspended soon after and in 1993 the decision to abandon the well, was made. Equipment refit and design, technical and environmental approvals consumed the next two years. The well head was relocated in the winter of 1995/96, an ice platform was built, an array of purpose-built equipment was assembled and moved to the site, a subsea reconnection was completed, the wellhead was successfully function and pressure tested, the well re-entered and permanently plugged. The subsea tree and associated flowline equipment were decommissioned and abandoned in-situ, and a two-year surface restoration program was initiated. The abandonment of Drake F-76 demonstrated the feasibility of (1) re-entering and abandoning a live gas well from a floating ice platform, (2) adapting a conventional service rig to handle subsea equipment, and (3) the use of conventional wireline and coiled tubing techniques on an offshore ice platform application. 2 refs., 8 figs

Scope of current abandonment issues in the oil and gas industry  

International Nuclear Information System (INIS)

Abandonment issues in the oil and gas industry, such as well sites, batteries, gas plants, compressor stations, and pipelines, were discussed. Responsibilities of the Canadian Association of Petroleum Producers (CAPP) for informing the Canadian public about energy and environmental issues on behalf of the upstream petroleum industry were reviewed. Industry regulators and those who have jurisdiction over the abandonment of facilities were identified. In Alberta, the main agencies are the Alberta Energy and Utilities Board, Alberta Environmental Protection, and Alberta Food and Rural Development in addition to the National Energy Board and Indian Oil and Gas Canada. At the end of 1995, 160,000 wells had been drilled in Alberta of which 60,000 are still active, 35,000 are suspended and 70,000 wells have been abandoned. The industry-financed Orphan Well Program was established to provide funds for facility abandonment, decontamination and surface reclamation costs associated with orphaned facilities. CAPP agrees that operators of oil and gas facilities must be held responsible and accountable for the abandonment of their facilities. CAPP is looking for support from government to ensure that enforcement actions limit the number of orphan facilities. tabs., figs

The pipeline service obligation under changing LDC purchasing practices  

International Nuclear Information System (INIS)

Historically, interstate natural gas pipelines served as aggregators and transporters of gas supplies from the producing fields to the city-gate. In turn, local distribution companies (LDCs) bought gas from pipelines at the city-gate under long-term sales contracts and resold the gas to retail customers. Once a pipeline/LDC sales relationship was established through a regulated certificate process, the LDC was assured of gas supply up to the level of its contract demand (CD) at just and reasonable rates until abandonment of the pipeline's sales service obligation was granted by the Federal Energy Regulatory Commission (FERC). During the years of regulated wellhead pricing and limited gas deliverability, pipelines signed long-term take-or-pay contracts with producers to induce them to develop and commit new gas supplies. Those supply cost obligations were reflected in tariff minimum bill provisions. For years, this pipeline/LDC arrangement was mutually beneficial and provided assured firm service. With the load diversity on large interstate pipeline systems and the make-up provisions under take-or-pay clauses, these gas purchase contracts provided supply reliability without negative economic consequence to the pipelines. Then, with the issuance of FERC Order Nos. 380, 436, and 500, LDCs' obligations to purchase gas from pipeline suppliers according to the terms of those long term sales agreements were irrevocably altered. The impacts of those long term sales agreementsmpacts of those long term sales agreements were irrevocably altered. The impacts of those orders the elimination of minimum bills and the advent of open access transportation caused a serious erosion of the mutual obligations between pipelines and their LDC customers. The result has been a significant loss of pipeline sales markets as LDC customers have chosen alternative supplied, often at the urging of state public utility commissions (PUCs) to lower short-term costs

Pipeline integrity inspections  

Energy Technology Data Exchange (ETDEWEB)

The conference paper gives a short description of the strategies within Statoil Gas Transport for pipeline condition monitoring and control. This is done for ensuring that the pipeline integrity can be maintained during all phases from construction to operation. Efficient condition monitoring and control can only be performed if the total pipeline integrity is taken into consideration such as design conditions, experience, environmental information, and general improved knowledge or the like for determining the requirement of inspection. Such philosophy will ensure the pipeline integrity better as corrective actions can be taken at a very early stage before any damage to the pipeline system have developed. 1 fig.

Focus on safety : a comparative analysis of pipeline safety performance  

International Nuclear Information System (INIS)

Canada's National Energy Board (NEB) regulates the design, construction, operation and abandonment of interprovincial and international pipelines within Canada. This publication provides a review of the safety performance of the NEB-regulated oil and gas pipeline industry. It is based on data received through incident reporting under the 1999 Onshore Pipeline Regulations and Safety Performance Indicators. In an effort to assess the performance of NEB-regulated pipelines relative to pipelines constructed under other organizations, a comparison is provided between the performance of NEB-regulated pipeline companies and those of external reference organizations. Details on safety performance from January 1, 2000 to December 31, 2001 were presented. The 6 key indicators that provide comprehensive measures of safety performance for pipeline companies include: fatalities; ruptures; injury frequencies; liquid hydrocarbon releases; gas releases; and, damage prevention. This report reveals that safety has improved in some areas, such as damage due to excavations, but the Board is still concerned about an increase in the rate of contractor injury. However, the Board also acknowledges that accurate projections cannot be made based on 2 years of data. The safety performance of NEB-regulated pipelines is consistent with reference organizations with some exceptions. There was a significant difference in data between 2000 and 2001, some of which is due to the completion of major conhich is due to the completion of major construction projects. There were no fatalities recorded by NEB-regulated pipeline companies. The number of ruptures increased from 1 in 2000 to 2 in 2001, with the leading cause being pipeline corrosion and the second most common cause being operational errors. The number of spills decreased from 265 in 2000 to 55 in 2001. The high number of spills in 2000 was due, in part, to the high level of construction activity. refs., 6 tabs., 14 figs

Geotechnical risks affecting pipelines : the Bolivia-Brazil natural gas pipeline experience  

Energy Technology Data Exchange (ETDEWEB)

Geotechnical management practices for pipelines can minimize the risk of accidents caused by hazards such as landslides, foundation subsidence, settlement and erosion. This paper summarized the geotechnical risks affecting pipelines and presented some examples of practical work done by Transportadora Brasileira Gasoduto (TBG) along the longest pipeline in South America, the Bolivia-Brazil natural gas pipeline. TBG is also responsible for the maintenance and operation of the 2593 km long pipeline which spans from Rio Grande in Bolivia to Canoas in southern Brazil. The pipeline crosses a range of difficult topography where both natural and human hazards can lead to high stress levels that can reach the steel yield strength limit and result in ruptures. The traction, compression, inflection or strain depend on the direction of the movement and the pipe position. The area most prone to geotechnical hazards is in the south due to its hard topography and a variety of geological materials such as colluvium deposits and debris flows. The right-of-way geotechnical risks that affect the pipeline were presented along with some of the practical remedial work that has been done by TBG along the pipeline route. The integrity management plans and the adopted actions that prevent geotechnical accidents were also presented. It was concluded that geotechnical hazard mapping should be emphasized in the planning phase of pipelines. New technologies such as the GEOPIG inspection tool combined with traditional preventive measures can effectively detect landslide areas. 2 refs., 2 tabs., 18 figs.

Canadian pipeline transportation system : transportation assessment  

International Nuclear Information System (INIS)

In addition to regulating the construction and operation of 70,000 km of oil and natural gas pipelines in Canada, the National Energy Board (NEB) regulates the trade of natural gas, oil and natural gas liquids. This report provided an assessment of the Canadian hydrocarbon transportation system in relation to its ability to provide a robust energy infrastructure. Data was collected from NEB-regulated pipeline companies and a range of publicly available sources to determine if adequate pipeline capacity is in place to transport products to consumers. The NEB also used throughput and capacity information received from pipeline operators as well as members of the investment community. The study examined price differentials compared with firm service tolls for transportation paths, as well as capacity utilization on pipelines and the degree of apportionment on major oil pipelines. This review indicated that in general, the Canadian pipeline transportation system continues to work effectively, with adequate pipeline capacity in place to move products to consumers who need them. 9 tabs., 30 figs., 3 appendices.

Pipeline Decommissioning Trial AWE Berkshire UK - 13619  

International Nuclear Information System (INIS)

This Paper details the implementation of a 'Decommissioning Trial' to assess the feasibility of decommissioning the redundant pipeline operated by AWE located in Berkshire UK. The paper also presents the tool box of decommissioning techniques that were developed during the decommissioning trial. Constructed in the 1950's and operated until 2005, AWE used a pipeline for the authorised discharge of treated effluent. Now redundant, the pipeline is under a care and surveillance regime awaiting decommissioning. The pipeline is some 18.5 km in length and extends from AWE site to the River Thames. Along its route the pipeline passes along and under several major roads, railway lines and rivers as well as travelling through woodland, agricultural land and residential areas. Currently under care and surveillance AWE is considering a number of options for decommissioning the pipeline. One option is to remove the pipeline. In order to assist option evaluation and assess the feasibility of removing the pipeline a decommissioning trial was undertaken and sections of the pipeline were removed within the AWE site. The objectives of the decommissioning trial were to: - Demonstrate to stakeholders that the pipeline can be removed safely, securely and cleanly - Develop a 'tool box' of methods that could be deployed to remove the pipeline - Replicate the conditions and environments encountered along the route of the pipeline The onsite trial was also designed to replicate the physical prevailing conditions and constraints encountered along the remainder of its route i.e. working along a narrow corridor, working in close proximity to roads, working in proximity to above ground and underground services (e.g. Gas, Water, Electricity). By undertaking the decommissioning trial AWE have successfully demonstrated the pipeline can be decommissioned in a safe, secure and clean manor and have developed a tool box of decommissioning techniques. The tool box of includes; - Hot tapping - a method of breaching the pipe while maintaining containment to remove residual liquids, - Crimp and shear - remote crimping, cutting and handling of pipe using the excavator - Pipe jacking - a way of removing pipes avoiding excavations and causing minimal disturbance and disruption. The details of the decommissioning trial design, the techniques employed, their application and effectiveness are discussed and evaluated here in. (authors)

Upstream pipelines : inspection, corrosion and integrity management  

Energy Technology Data Exchange (ETDEWEB)

Working Group 3 discussed issues regarding the inspection, corrosion and integrity management of upstream oil and gas pipelines. It entailed 7 sessions in which issues from the 2005 symposium were reviewed with particular reference to aging pipelines, new materials and inspection of construction. Working Group 3 also discussed internal corrosion monitoring; inline inspection; topical issues; integrity issues for upstream pipeline operators as stipulated in the Canadian Standards Association's Annex N; and non-metallic pipelines. The effect of metallurgy on localized corrosion and localized pitting corrosion was discussed along with corrosion rates and the need for absolute numbers. Solids deposition in oil pipelines versus gas pipelines were reviewed along with probability and reliability based modelling. Carbon dioxide flooding and sequestration was also discussed, with reference to internal monitoring through the Upstream Pipeline Integrity Management Association (UPIMA) and the National Association of Corrosion Engineers (NACE). It was recommended that the industry could benefit from an unbiased database of failures and that the coordination of product testing would be useful. In this regard, a specification by the Canadian Association of Petroleum Producers would be useful for manufacturers and installers. tabs., figs.

Abandoned mine land reclamation plan  

Energy Technology Data Exchange (ETDEWEB)

The responsibility of an abandoned mine land reclamation plan must be to gather information concerning the number of acres, location, ownership, condition, environmental damage resulting from the condition, the cost of acquiring and reclaiming the land. Possible future uses, legal tools available to the state, and incentives to private interests in reclaiming the land must be considered. Factors which should be dealt with when compiling this information include: geology, topography, surface drainage, the productivity and structural qualities of the soils, habitat and vegetation, climatological data, existing land use and a visual analysis. Information necessary in making determinations concerning future land uses include: socio-economic characteristics, demographic trends, historical development, transportation and water supply. This study demonstration project concerns itself with the area located within the southeastern portion of Macoupin County, 60 miles southwest of Springfield, Illinois. In general, the groundwater from shallow wells in the area is very hard and contains large quantities of iron. The surface waters have also been affected to some degree by the refuse piles.

Pediatric Medical Care System in China Has Significantly Reduced Abandonment of Acute Lymphoblastic Leukemia Treatment.  

Science.gov (United States)

In this study, we have analyzed both administrative and clinical data from our hospital during 2002 to 2012 to evaluate the influence of government medical policies on reducing abandonment treatment in pediatric patients with acute lymphoblastic leukemia. Two policies funding for the catastrophic diseases and the new rural cooperative medical care system (NRCMS) were initiated in 2005 and 2011, respectively. About 1151 children diagnosed with acute lymphoblastic leukemia were enrolled in our study during this period and 316 cases abandoned treatment. Statistical differences in sex, age, number of children in the family, and family financial status were observed. Of most importance, the medical insurance coverage was critical for reducing abandonment treatment. However, 92 cases abandoning treatment after relapse did not show significant difference either in medical insurance coverage or in duration from first complete remission. In conclusion, financial crisis was the main reason for abandoning treatment. Government-funded health care expenditure programs reduced families' economic burden and thereby reduced the abandonment rate with resultant increased overall survival.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivitives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

Pipelined Viterbi Decoder Using FPGA  

OpenAIRE

Convolutional encoding is used in almost all digital communication systems to get better gain in BER (Bit Error Rate), and all applications needs high throughput rate. The Viterbi algorithm is the solution in decoding process. The nonlinear and feedback nature of the Viterbi decoder makes its high speed implementation harder. One of promising approaches to get high throughput in the Viterbi decoder is to introduce a pipelining. This work applies a carry-save technique, which gets the advantag...

The rail abandonment process: A southern perspective  

International Nuclear Information System (INIS)

One factor in evaluating the desirability of rail transport for high-level radioactive wastes or spent fuels is the frequency, or lack thereof, with which railroad and railroad lines have been, and are, abandoned. If DOE makes a decision to use the rail option and a line is subsequently abandoned, the choice results in increased cost, time delays and possibly safety problems: Information is therefore needed prior to the decision-making process to evaluate the desirability of the rail shipping option. One result of the abandonments mentioned herein, as well as other later abandonments, is the creation of a US rail system undergoing an evolutionary process in the 1980s as far-reaching as the changes that occurred when the industry was in its infancy a century and-a-half ago. The purpose of this paper is to examine the factors leading to some of these changes by tracing the historical development of the rail abandonment process, with particular emphasis on the rise of regional railroads, their problems in the modern era and current trends in rail abandonments as well as their effects on the southeastern United States

Solutions for small slope pipeline lifting problems  

Energy Technology Data Exchange (ETDEWEB)

Two classes of submarine pipeline handling problems are considered, namely the lifting of a pipe with a free end for tie-in purposes, and the raising of part of a continuous line for hot-tapping or repair. If pipeline slopes are small (as is usual in seabed work), engineers' beam theory may be used in combination with a NewtonRaphson solution to locate the separation points between pipe and seabed. Key results are presented.

Remarks to the risk assessment for abandoned mine sites  

Directory of Open Access Journals (Sweden)

Full Text Available The authors give some remarks to the term risk regarding its use for the assessment of abandoned mine sites. These remarks are based on the recommendation Geotechnical Investigation and Evaluation of Abandoned Mine Sites developed by the working committee Abandoned Mining of the German Society for Geotechnical Engineering (DGGT and the German Society for Mine Surveying (DMV, published in 2004.By this recommendation, the risk is defined as a product of the occurrence probability and the extent of damage of an unwanted event. The occurrence probability for each unwanted event is described by the linguistic terms in all probability, probable, less probable or practically impossible. The extent of damage for each unwanted event is described by the linguistic terms insignificant, small, high or very high. A matrix out of these terms is used to define schematically an explicit limiting risk for each unwanted event.The authors point out that a schematic determination of limiting risk should be supported by an unique and comprehensible evaluation of all significant risk factors and parameters influencing the extent of damage. Fuzzy sets can be used instead of a discreet classification leading to more plausible results. The processing of linguistic terms by a fuzzy logic system is demonstrated.

Slurry pipeline design approach  

Energy Technology Data Exchange (ETDEWEB)

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

Pipeline AC mitigation misconceptions  

Energy Technology Data Exchange (ETDEWEB)

This paper discussed methods of mitigating the impact of AC voltages on nearby pipelines. Various standards have been established to protect personnel from the electrical hazards of pipelines exposed to AC voltages. Pipelines are susceptible to corrosion when soil resistivity is less than 15,000 Ohm cm. AC corrosion is a function of AC current density and the coating holiday geometry, and an AC current density threshold must be established as part of an effective mitigation system. Most calculation methods for AC mitigation do not distinguish between pipe voltages. Distributed grounding and gradient control mats can be used at pipeline appurtenances when induced voltages exceed 15 V. Fault shields can also be used to reduce coating stress on pipelines near faulted towers. The study concluded by stating that adherence to voltage stress limits for fault conditions can result in the over-design of AC mitigation systems. 9 refs., 8 figs.

Pipelines 'R' us  

International Nuclear Information System (INIS)

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 me in a position to export its oil via as many as half a dozen different routes.

Steam pipelines' effort and durability  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: The main problem addressed in the paper is the description of an effort and durability of steam pipelines under the conditions of mechanical and thermal interactions.Design/methodology/approach: The FEM modelling has been used to determine the stress and strain fields in the pipelines and to describe their behaviour under mechanical and thermal loading.Findings: An appropriate model description has been developed. So far, experimental verification of the usefulness of the model description to determine the stress and strain patterns in particular object and for chosen operation conditions has been made. The analysis made has shown that the most probable cause of cracks occurrence on the analyzed chosen pipeline’ inner surfaces are thermal deformations and constraints of their dislocations.Research limitations/implications: The developed description should be useful in problems of behaviour predictions of high temperature components and their durability assessment under different mechanical and thermal loadings in industry practical applications.Originality/value: The method, which more precise description of power industry components behaviour makes possible have been shown in the work. The work is addressed to researchers interested in problems of component behaviour prediction under different loadings that we can meet in the operation practice and to power industry engineering maintenance staff.

Energy Technology Data Exchange (ETDEWEB)

One of the Environmental Programmes developed for the works of Cabiunas-Vitoria Gas Pipeline (GASCAV) intended to fulfill the conditions of the Installation License, which defined the preparation of Specific Studies and Environmental Programmes to five quilombo communities located at GASCAV's influence area. The challenge of PETROBRAS/Engenharia/IETEG/IEDT Environmental Team was to align the Company's strategic guidelines related to Environmental and Social Responsibility to the necessary criteria for the approval of this Programme by environmental agencies which inspected the Programme: IBAMA (Brazilian Institute of Environment and Renewable Natural Resources) and FCP (Palmares Cultural Foundation). This work aimed to present the methodology adopted to the proposal of the Environmental Education Programme to Quilombo Communities, as well as to discuss the results achieved with the implementation of this Programme. The results allowed to conclude that the actions developed at the quilombo communities has disseminated the environmental concepts and related to the afro culture, has established partnerships and strengthen the relationship with the surrounding communities. This fact promotes the integration of the Work's economic interests with the social and environmental ones, generating a socio environmental conscience among the residents. (author)

Citizenship program in near communities of pipelines  

Energy Technology Data Exchange (ETDEWEB)

During the construction of a pipeline, the IENE - Engineering Unit of PETROBRAS, responsible for the construction and erection of pipelines and related plants in northeastern Brazil, crossed more than 7 states and 250 counties, had implemented a social responsibility program, in special a citizenship program. This action was the result of community studies located near of the pipelines AID - Direct Influence Area (438 yards right and left of the pipeline) and through the evidence that those locations were poor and have no personal documents and citizen position in society. This paper intents to share the experience of IENE about its citizen program that worked in three big lines: community mobilization; citizenship qualification; and citizenship board. This last one, turns possible to people obtains theirs personal documents and exercise the plenitude of citizenship. (author)

History of abandoned infants in Greece  

Directory of Open Access Journals (Sweden)

Full Text Available It is since mythology to classical ages in Greece, since Medieval Ages to the end of the 19th century in Smyrna and in Athens, that history indicates the abandonment of the infants as a phenomenon always existing. A time flashback and the research of the phenomenon through the historic examples contribute unequivocally to the remonstrance of the social facts in each era.Aim: The aim of this study was to critically review all the historical data and the evidence from the international and Greek literature and to explore the factors that are accountable for to the infant’s abandonment and especially in Greece.Method: A critical literature search was performed using of MEDLINE and CINAHL (1990-2008 databases. The literature review referred to historical data related to the care of the abandoned infants since ancient Greek times.Conclusion: The literature review leads to the conclusion that the detection of the historical sources combines a “mosaic” which reflects the multiple needs of the Greek society, with target to encounter the infant abandonment. The ways used each time in order the phenomenon to be faced, not rarely were doubted. Still they stand as the salutary solutions for the abandoned infants and they are explained and established through the social background of each era and through the needs serviced each time.

Pipeline Drag Reducers  

International Nuclear Information System (INIS)

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 %

Effects of laminations in pipes to resistance and working life of pipelines; Auswirkung von Doppelungen in Rohren auf die Festigkeit und die Lebensdauer von Mineraloelfernleitungen  

Energy Technology Data Exchange (ETDEWEB)

The effect of load cycles on pipes with laminations was examined to obtain information about the effects on resistance and working life. Material tests carried out in connection with threshold load tests showed that laminations or also segregations in pipes welded with longitudinal seams always run parallel to the surface and that even with the slight enlargement that sometimes occurs under threshold loading, resistance and working life are not reduced. (orig.) [Deutsch] Die Auswirkung von dynamischen Belastungen auf dopplungsbehaftete Rohre wurde untersucht, um Erkenntnisse hinsichtlich der Beeinflussung auf die Festigkeit der Lebensdauer zu gewinnen. Durchgefuehrte Werkstoffuntersuchungen im Zusammenhang mit Schwelllastversuchen zeigten, dass Doppelungen oder auch Seigerungen in laengsnahtgeschweissten Rohren immer oberflaechenparallel verlaufen und dass selbst bei der unter Schwellastbeanspruchung teilweise eingetretenen geringfuegigen Vergroesserung die Festigkeit und die Lebensdauer nicht eingeschraenkt wird.

Design of deepwater pipelines  

Science.gov (United States)

For pipelines to be laid offshore in water depths greater than about 3000 feet, pipe design will be governed primarily by external pressure (collapse) considerations and internal pressure (burst) considerations. The paper presents a set of design criteria for deepwater pipelines, based on results of Shell's Deepwater Pipeline Feasibility Study (1), as well as comparisons with other experimental and theoretical results. The design criteria, in general, establish limits on the wall thickness, yield stress, initial imperfections, and pipe weight, in terms of the maximum internal operating pressure, the maximum external pressure or water depth, and the near-bottom ocean currents.

In this paper, we report the environmental radioactivity survey in an abandoned uranium mine in China. The air gamma ray absorption dose rate was measured. Radionuclides in uranium mine slag, soil, water, sediment and biological samples, were analyzed. Radon in the air was monitored. The annual radiation dose of the residents in the uranium mine region was assessed. All the work was conducted in line with national standards of China. The survey results show that the radioactive pollution in the region should be disposed immediately. According to the characteristics of the uranium mining pollution sources, we propose some reasonable ways of radiation protection and disposal. (authors)

Infanticide and illegal infant abandonment in Malaysia.  

Science.gov (United States)

Infant abandonment and infanticide are poorly understood in Malaysia. The information available in the public arena comes predominantly from anecdotal sources. The aim of this study was to describe the prevalence and characteristics of infanticide and illegal infant abandonment in Malaysia and to estimate annual rates for the most recent decade. Summaries of data about infanticide and illegal infant abandonment were gathered from police records; the annual number of live births was ascertained from the national registry. The estimated inferred infanticide rates for Malaysia were compared with the infanticide rates among countries of very high, high, medium, and low rankings on the Human Development, Gender Inequality, and Gini indices. From 1999 to 2011, 1,069 cases of illegal infant abandonment were recorded and 1,147 people were arrested as suspected perpetrators. The estimated inferred infanticide rate fluctuated between 4.82 and 9.11 per 100,000 live births, a moderate rate relative to the infanticide rates of other countries. There are substantial missing data, with details undocumented for about 78-87% of cases and suspected perpetrators. Of the documented cases, it appeared that more boys than girls were victims and that suspected perpetrators were predominantly Malays who were women, usually mothers of the victim; the possibility of arrest bias must be acknowledged. Economic and social inequality, particularly gender inequality, might contribute to the phenomena of infanticide and abandonment. Strategies to reduce rates of infanticide and illegal infant abandonment in Malaysia will require strengthening of the surveillance system and attention to the gender-based inequalities that underpin human development.

This report will explore the hypothesis that an underground cavity in gassy salt will eventually be gas filled as is observed on a small scale in some naturally occurring salt inclusions. First, a summary is presented on what is known about gas occurrences, flow mechanisms, and cavern behavior after abandonment. Then, background information is synthesized into theory on how gas can fill a cavern and simultaneously displace cavern fluids into the surrounding salt. Lastly, two-phase (gas and brine) flow visualization experiments are presented that demonstrate some of the associated flow mechanisms and support the theory and hypothesis that a cavity in salt can become gas filled after plugging and abandonment

Cleaning-up abandoned uranium mines in Saskatchewan's North  

Energy Technology Data Exchange (ETDEWEB)

Thirty-six now-abandoned uranium mine and mill sites were developed and operated on or near Lake Athabasca, in Northern Saskatchewan, Canada, from approximately 1957 through 1964. During their operating lifetimes these mines produced large quantities of ore and tailings. After closure in the 1960's, these mine and mill sites were abandoned with little remediation and no reclamation being done. The governments of Canada and Saskatchewan are now funding the cleanup of these abandoned northern uranium mine and mill sites and have contracted the management of the project to the Saskatchewan Research Council (SRC). The clean-up activity is underway, with work at many of the smaller sites largely completed, work at the Gunnar site well underway, and a beginning made at the Lorado site. This lecture presents an overview of these operations. (author)

Pipelines to eastern Canada  

International Nuclear Information System (INIS)

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

Transient leak detection in crude oil pipelines  

Energy Technology Data Exchange (ETDEWEB)

Nord-West Oelleitung (NWO) operates 2 crude oil pipelines from Wilhemshaven to Koln and Hamburg respectively. German regulations for transporting flammable substances stipulate that 2 independent continuously working procedures be used to detect leaks. Leak detection pigs are used routinely to complement the surveillance system. This paper described the specific issues of transient leak detection in crude oil pipelines. It was noted that traditional methods have failed to detect leaks that occur immediately after pumps are turned on or off because the pressure wave generated by the transient dominates the pressure wave that results from the leak. Frequent operational changes in a pipeline are often accompanied by an increased number of false alarms and failure to detect leaks due to unsteady operations. NWO therefore decided to have the Atmos statistical pipeline leak detection (SPLD) system installed on their pipelines. The key to the SPLD system is the sequential probability ratio test. Comprehensive data validation is performed following reception of pipeline data from the supervisory control and data acquisition (SCADA) system. The validated data is then used to calculate the corrected flow imbalance, which is fed into the SPRT to determine if there is an increase in the flow imbalance. Pattern recognition is then used to distinguish a leak from operational changes. The SPLD is unique because it uses 3 computational pipeline monitoring methods simultaneously, namely modified volume balance, statistical analysis, and pressure and flow monitoring. The successful installation and testing of the SPLD in 2 crude oil pipelines was described along with the main difficulties associated with transient leaks. Field results were presented for both steady-state and transient conditions. 5 refs., 2 tabs., 16 figs.

Development of database on circular abandoned channel in Japan  

International Nuclear Information System (INIS)

To develop a method for estimating late Quaternary uplift rates of inland mountainous terrains where fluvial terraces are poorly developed, we focused on 'circular abandoned channels', formed by meander cut-offs or river capture of an incised meandering river. We studied about 1,000 circular abandoned channels distributed throughout the Islands of Japan, and developed GIS database on circular abandoned channel in Japan. This database contains formation process, relative heights, degree of dissection and bedrocks of circular abandoned channels. Circular abandoned channels are distributed in inland mountainous terrains, where late Quaternary uplift rates are unknown, and indicate different relative heights along the same river. Relative heights tend to correlate with degree of dissection of the circular abandoned channels, which may indicate that degree of dissection correlate with ages of abandonment of circular abandoned channels. A CD-ROM is attached as an appendix. (J.P.N.)

Severe service ball valves for high pressure slurry pipelines  

Energy Technology Data Exchange (ETDEWEB)

Severe Service Ball Valves are a critical component in the design of high pressure slurry pipelines. Compared to conventional oil and gas pipelines, the transportation of mineral slurries at high pressure is a modern technology. This advanced technology would not be possible if valve manufacturers were not able to design and provide equipment that can function with high pressure abrasive fluids. The design of slurry pipelines has become more complicated due to the use of sophisticated controls, varying types of minerals, increased sizes and higher pressures. All of these complexities have challenged valve and actuator manufacturers who need to work closely with the pipeline design companies to find cost-effective and viable solutions. Using examples from existing slurry pipeline operations; this paper examines how high pressure slurry ball valves have become an important component in the successful design, construction and operations of slurry pipelines throughout the world.

Worries mount over ability to finance pipeline nukes  

International Nuclear Information System (INIS)

Concerns over financing the 31 nuclear power plants now in the construction pipeline lead some analysts to question whether plants not already slated for cancellation will be able to survive the increasingly risky investment climate. Any accident or utility default could weaken marginally healthy utilities to the point of default on construction bonds. Junk bonds that spread the percentage points of interest rates are competing in the market with those of other businesses. Regulatory decisions that protect ratepayers increase the risk to investors. The industry needs about $40 billion to finish the plants now in the pipeline, and much of the capital must come from internal generation. Adding to the risk are challenges to emergency and safety procedures, but optimistic analysts feel the market for high risk/high return securities has not reached saturation. One problem is the lack of standardization in calculating the estimated costs of completion versus abandonment. 3 tables

Water level detection pipeline  

International Nuclear Information System (INIS)

In the present invention, water levels of a feedwater heater and a drain tank in a nuclear power plant are detected at high accuracy. Detection pipeline headers connected to the upper and lower portions of a feedwater heater or a drain tank are connected with each other. The connection line is branched at appropriate two positions and an upper detection pipeline and a lower detection pipeline are connected thereto, and a gauge entrance valve is disposed to each of the detection pipelines. A diaphragm of a pressure difference generator is connected to a flange formed to the end portion. When detecting the change of water level in the feedwater heater or the drain tank as a change of pressure difference, gauge entrance valves on the exit side of the upper and lower detection pipelines are connected by a connection pipe. The gauge entrance valve is closed, a tube is connected to the lower detection pipe to inject water to the diaphragm of the pressure difference generator passing through the connection pipe thereby enabling to calibrate the pressure difference generator. The accuracy of the calibration of instruments is improved and workability thereof upon flange maintenance is also improved. (I.S.)

CPL: Common Pipeline Library  

Science.gov (United States)

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

Pipeline rehabilitation planning  

Energy Technology Data Exchange (ETDEWEB)

An operator faced with an onshore pipeline that has extensive damage must consider the need for rehabilitation, the sort of rehabilitation to be used, and the rehabilitation schedule. This paper will consider pipeline rehabilitation based on the authors' experiences from recent projects, and recommend a simple strategy for planning pipeline rehabilitation. It will also consider rehabilitation options: external re-coating; internal lining; internal painting; programmed repairs. The main focus will be external re-coating. Consideration will be given to rehabilitation coating types, including tape wraps, epoxy, and polyurethane. Finally it will discuss different options for scheduling the rehabilitation of corrosion damage including: the statistical comparison of signals from inspection pigs; statistical comparison of selected measurements from inspection pigs and other inspections; the use of corrosion rates estimated for the mechanisms and conditions; expert judgement.

Northern pipelines : backgrounder  

International Nuclear Information System (INIS)

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 Highwayn 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

Explosives remain preferred methods for platform abandonment  

International Nuclear Information System (INIS)

Economics and safety concerns indicate that methods involving explosives remain the most practical and cost-effective means for abandoning oil and gas structures in the Gulf of Mexico. A decade has passed since 51 dead sea turtles, many endangered Kemp's Ridleys, washed ashore on the Texas coast shortly after explosives helped remove several offshore platforms. Although no relationship between the explosions and the dead turtles was ever established, in response to widespread public concern, the US Minerals Management Service (MMS) and National Marine Fisheries Service (NMFS) implemented regulations limiting the size and timing of explosive charges. Also, more importantly, they required that operators pay for observers to survey waters surrounding platforms scheduled for removal for 48 hr before any detonations. If observers spot sea turtles or marine mammals within the danger zone, the platform abandonment is delayed until the turtles leave or are removed. However, concern about the effects of explosives on marine life remains

Fiber optic accelerometer for pipeline surveillance  

Energy Technology Data Exchange (ETDEWEB)

The use of accelerometers for monitoring vibration due to impacts and other sources associated with pipeline operation is not new, but conventional electric accelerometers present practical problems to be deployed in the field. In this paper we evaluate the use of both commercially available and prototypes of new optical fiber accelerometers for this application. They all share the possibility of operating at long distances from the reading unit. All tests were performed at CTDUT facilities on free pipes as well as on a 14 pol-OD, 100 meters long pipeline loop. Using controlled impacts, several aspects of the application have been analyzed such as different ways of fixing the accelerometers to the pipeline wall, influence of barriers between impact and sensor, and signal propagation through buried sections of pipeline. Results of measurements performed during the operation of the loop are also presented. They include passing PIGs, pumping water out from the system, and working on the tubes to open the loop. Results indicate that the accelerometers can be placed at distances measuring hundreds of meters from the source of vibration, and that the difference in time and frequency behavior of signals measured by sensors placed in different locations along the pipeline may be used to locate and identify that source.

Hazard identification studies applied to oil pipelines  

Energy Technology Data Exchange (ETDEWEB)

In order to assess risks inherent to an Oil Pipeline, it is imperative to analyze what happens 'outside the process'. HAZID (HAZard IDentification) studies are mainly carried out for this purpose. HAZID is a formal study which identifies hazards and risks associated to an operation or facility and enable its acceptability assessment. It is a brainstorming exercise guided by a typical 'Checklist', divided into four Sections: External, Facilities and Health Hazards and Issues pertaining to Project Execution, which are further subdivided into Hazard Categories. For each Category, there are 'Guide-words' and 'Prompts'. Even if an Oil Pipeline Risk Assessment can be performed by means of the above referred 'Checklist', carrying out the actual process can become lengthy and annoying due to the lack of specificity. This work aims at presenting the most suitable 'Checklist' for the identification of Oil Pipeline Risk Assessment, although it could be used for Gas Pipeline Risk Assessment too. Prepared ad hoc, this list, is based on the spill causes established by CONCAWE (CONservation of Clean Air Water in Europe). Performing Oil Pipeline Risk Assessment by means of specially formulated Checklist enables the Study Team to easily identify risks, shortens execution time and provides both accuracy and specificity.

The JWST Calibration Pipeline

The James Webb Space Telescope will launch in 2018 and carry four science instruments that will observe the sky at 0.7 - 29 micron: the Near Infrared Camera (NIRCam), the Near Infrared Imager and Slitless Spectrograph (NIRISS), the Near Infrared Spectrograph (NIRSpec), and the Mid Infrared Instrument (MIRI). The Space Telescope Science Institute (STScI) is currently building a data reduction pipeline that will provide not only basic calibrated data but also higher level science products. All of the JWST detectors will be operated in non-destructive readout mode. Therefore, the first step in the pipeline will be to calculate the slopes of indivudal non-destructive readout ramps or integrations. The next step will be to generate calibrated slope images that are represent the basic calibrated data. The final step will be to combine data taken across multiple integrations and exposure. For the direct imaging and integral field spectroscopy modes, the pipeline will produce calibrated mosaicks. For the coronagraphic modes, the pipeline will produce contrast curves and PSF subtracted images.

Deep water construction on live oil and gas pipelines using the SmartPlug high-pressure pipeline isolation tools  

Energy Technology Data Exchange (ETDEWEB)

The world first successful SmartPlug operation took place at the Dimlington process plant in UK in 1999. Since 1999, the SmartPlug system has been deployed on more than 80 projects worldwide allowing the operators to perform pipeline repair work, modifications, or tie-ins with the pipeline systems full of product, and at full production pressure. Mid-line applications of the SmartPlug system allows the operator to tie a new pipeline into an existing pipeline without displacing the oil or gas and eliminates time needed to flare, depressurize, empty the line and commission the line before start up. The first SmartPlug installations were done to isolate pig trap valves or ESD valve from the pipeline allowing the valve to be replaced at full pipeline pressure, and in some instances while production was flowing. Some pipelines have multiple platforms or fields tied in along the pipeline, and the SmartPlug system is frequently used to isolate a single platform to allow platform removal or riser repair without impacting the production flow in the remaining part of the pipeline system.

Orchestrator Telemetry Processing Pipeline  

Science.gov (United States)

Orchestrator is a software application infrastructure for telemetry monitoring, logging, processing, and distribution. The architecture has been applied to support operations of a variety of planetary rovers. Built in Java with the Eclipse Rich Client Platform, Orchestrator can run on most commonly used operating systems. The pipeline supports configurable parallel processing that can significantly reduce the time needed to process a large volume of data products. Processors in the pipeline implement a simple Java interface and declare their required input from upstream processors. Orchestrator is programmatically constructed by specifying a list of Java processor classes that are initiated at runtime to form the pipeline. Input dependencies are checked at runtime. Fault tolerance can be configured to attempt continuation of processing in the event of an error or failed input dependency if possible, or to abort further processing when an error is detected. This innovation also provides support for Java Message Service broadcasts of telemetry objects to clients and provides a file system and relational database logging of telemetry. Orchestrator supports remote monitoring and control of the pipeline using browser-based JMX controls and provides several integration paths for pre-compiled legacy data processors. At the time of this reporting, the Orchestrator architecture has been used by four NASA customers to build telemetry pipelines to support field operations. Example applications include high-volume stereo image capture and processing, simultaneous data monitoring and logging from multiple vehicles. Example telemetry processors used in field test operations support include vehicle position, attitude, articulation, GPS location, power, and stereo images.

Risk from transport of gas by pipeline ''kokui-perm''  

International Nuclear Information System (INIS)

Full text of publication follows: the length of gas pipelines in Russia is 142 thousands km, 62 % are pipelines of the large diameters. Annually on gas pipelines in Russia there are more than 70 large accidents, more than 50 % from them is accompanied by ignition of gas. The average ecological looses from accident is: destruction arable lands - 78 hectares; removing from consumption agricultural soils - 6,2 hectares; destruction forests - 47,5 hectares. In work the reasons of accidents on gas pipelines of different diameters are analyzed. So, for pipelines a diameter of 1220 mm by the reasons of accidents are: marriage of civil and erection works - 39, 1 %; outside corrosion - 35,9 %; mechanical damages - 9,4 %; defects of pipes - 6,2 %; defects of the factory equipment - 1,6 %; nature disasters and other reasons - 7,8 %. In work the results of risk analysis on a gas pipeline 'Kokui - Perm' are analysed. The gas pipeline 'Kokui - Perm' passes near 22 towns and countries, crosses 15 highways, 2 rail ways, 15 rivers. In work the concrete recommendations for management of risk and safety of the population are given. (author)

Electrical fingerprint of pipeline defects  

International Nuclear Information System (INIS)

Pipeline defects are dislocations that connect the source region of the transistor with the drain region. They were widely reported to occur in CMOS, BiCMOS devices and recently in SOI technologies. They can reduce device yield either by affecting the devices functionality or by increasing the current consumption under stand-by conditions. In this work the electrical fingerprint of these dislocations is studied, its purpose is to enable us to identify these defects as the ones responsible for device failure. It is shown that the pipeline defects are responsible for a leakage current from source to drain in the transistors. This leakage has a resistive characteristic and it is lightly modulated by the body bias. It is not sensitive to temperature; vice versa the off-current of a good transistor exhibits the well-known exponential dependence on 1/T. The emission spectrum of these defects was studied and compared with the spectrum of a good transistor. The paper aims to show that the spectrum of a defective transistor is quite peculiar; it shows well defined peaks, whereas the spectrum of a good transistor under saturation conditions is characterized by a broad spectral light emission distribution. Finally the deep-level transient spectroscopy (DLTS) is tried on defective diodes

Pipelined Viterbi Decoder Using FPGA  

Directory of Open Access Journals (Sweden)

Full Text Available Convolutional encoding is used in almost all digital communication systems to get better gain in BER (Bit Error Rate, and all applications needs high throughput rate. The Viterbi algorithm is the solution in decoding process. The nonlinear and feedback nature of the Viterbi decoder makes its high speed implementation harder. One of promising approaches to get high throughput in the Viterbi decoder is to introduce a pipelining. This work applies a carry-save technique, which gets the advantage that the critical path in the ACS feedback becomes in one direction and get rid of carry ripple in the “Add” part of ACS unit. In this simulation and implementation show how this technique will improve the throughput of the Viterbi decoder. The design complexities for the bit-pipelined architecture are evaluated and demonstrated using Verilog HDL simulation. And a general algorithm in software that simulates a Viterbi Decoder was developed. Our research is concerned with implementation of the Viterbi Decoders for Field Programmable Gate Arrays (FPGA. Generally FPGA's are slower than custom integrated circuits but can be configured in the lab in few hours as compared to fabrication which takes few months. The design implemented using Verilog HDL and synthesized for Xilinx FPGA's.

Pipeline corridors through wetlands  

International Nuclear Information System (INIS)

This paper presents preliminary findings from six vegetational surveys of gas pipeline rights-of-way (ROW) through wetlands and quantifies the impacts of a 20-year-old pipeline ROW through a boreal forest wetland. Six sites of various ages were surveyed in ecosystems ranging from coastal marsh to forested wetland. At all sites except one, both the number and the percentage of wetland species on the Row approximated or exceeded those in the adjacent natural area. The boreal forest study showed that (1) adjacent natural wetland areas were not altered in type; (2) water sheet flow restriction had been reversed by nature; (3) no nonnative plant species invaded the natural area; (4) three-quarters of the ROW area was a wetland, and (5) the ROW increased diversity

This paper presents preliminary findings from six vegetational surveys of gas pipeline rights-of-way (ROW) through wetlands and quantifies the impacts of a 20-year-old pipeline ROW through a boreal forest wetland. Six sites of various ages were surveyed in ecosystems ranging from coastal marsh to forested wetland. At all sites except one, both the number and the percentage of wetland species on the Row approximated or exceeded those in the adjacent natural area. The boreal forest study showed that (1) adjacent natural wetland areas were not altered in type; (2) water sheet flow restriction had been reversed by nature; (3) no nonnative plant species invaded the natural area; (4) three-quarters of the ROW area was a wetland, and (5) the ROW increased diversity.

Reclamation of abandoned underground mines in the United Kingdom  

International Nuclear Information System (INIS)

Since 1980, the Derelict Land Grant program has supported reclamation of abandoned mines in the United Kingdom. The stabilization of large-scale limestone mines in the West Midlands has stimulated the development of new methods of bulk infilling using waste materials as thick pastes. Colliery spoil rock paste develops strengths of 10 to 20 kPa to support roof falls and prevent crown hole collapse. Pulverized fuel ash rock paste develops strengths over 1 MPa where lateral support to pillars is required. Smaller scale mine workings in the West Midlands and elsewhere have been stabilized using conventional grouting techniques, hydraulic and pneumatic stowing, foamed-concrete infill, bulk excavation with controlled backfill, and structural support using bolts, mesh, and shotcrete

Integrated Software Pipelining  

OpenAIRE

In this thesis we address the problem of integrated software pipelining for clustered VLIW architectures. The phases that are integrated and solved as one combined problem are: cluster assignment, instruction selection, scheduling, register allocation and spilling. As a first step we describe two methods for integrated code generation of basic blocks. The first method is optimal and based on integer linear programming. The second method is a heuristic based on genetic algorithms. We then exte...

Pipeline vortex induced vibration  

International Nuclear Information System (INIS)

The pipeline induced vibration caused by a transversal external flow is studied, using the mathematical model developed by Griffin and Skop for flexible cylindrical structures. This model uses the modified Van der Pol equation, for the lift coefficient coupled to the oscilatory movement equation of a cylinder. The finite element method for spatial discretization is used. Numerical results are compared to approximated solutions obtained through the harmonic balance method. (E.G.)

Pipeline crawler gets inside information  

Energy Technology Data Exchange (ETDEWEB)

A new system that can x-ray more than 250 pipeline welds a day at a cost saving estimated at about 50% is being used by an Alberta company. Rivest Bros. Enterprises Ltd., a nondestructive testing company, is working on a 62 km gas transmission line for Saskatchewan Power Corp. The line runs from Bronson Lake to Beacon Hill and is a $6.3 million project with 6 and 12 in pipe and currently does 270 12-in weldsd. The unit is battery powered, self-propelled, 42 in long and weighs 65 lb. The crawler can examine 2 km of pipe without battery change or recharge and can climb a 45/sup 0/ slope. The unit is controlled from outside the pipe by an operator and uses Iridium 192 as its radiation source.

Filling the Graduate Student Pipeline  

Science.gov (United States)

As a professor who relies on graduate students to participate in my research program, I work to ensure that the pipeline of graduate students is full. This presentation will discuss a variety of strategies that I have used to advertise the opportunities of graduate school, many of which use existing infrastructure at the University of Pennsylvania. These strategies involve a combination of public speaking, discussion groups, and faculty advising. During these exchanges it's important to both contrast the career opportunities for B.S., M.S. and Ph.D. degree holders and outline the financial facts about graduate school. These modest efforts have increased the number of Penn undergraduates pursuing doctorate degrees.

Abandonment: Technological, organisational and environmental challenges  

International Nuclear Information System (INIS)

The paper deals with the abandonment of offshore wells. Decommissioning of offshore installations is a complex multi-disciplined issue, which raises a number of technical, organisational and environmental challenges. The success of a planned decommissioning operation depends on the development of a clear understanding of the complex blend of drivers which control the decommissioning process and their inter-relationship. Due to the complexity of the inter-relationship between the primary drivers one cannot separate the technological, organisational and environmental issues raised by the decommissioning of offshore installations. The optimal solution will be a compromise between all the decommissioning drivers mentioned in this paper. 5 figs., 3 tabs

Phase-in, abandonment, and cost disallowances  

International Nuclear Information System (INIS)

The major regulatory challenge to the electric utility industry appears to be coming from the financial side with its bookkeeping and financial reporting requirements. The author describes the accounting procedures and problems associated with straightforward phase-in rate treatment, abandonment, excess capacity, cost allowances, etc. She concludes that the available options to the Financial Accounting Standards Board are to adopt either the proposed exposure draft or a modification of the draft, to drop the proposed draft of amendments to Statement No. 71, or issue a whole new exposure draft

Should executive stock options be abandoned?  

OpenAIRE

Recent corporate scandals around the world have led many to single out executive stock options as one of the main culprits. More corporations are abandoning stock options and reverting to restricted stock. This paper argues that such a change is not entirely justifiable. We first provide a critical review of the pros and cons of executive stock options. We then compare option-based contracts with stock-based contracts using a simple principal-agent model with moral-hazard. In a general ...

The visual and radiological inspection of a pipeline using a teleoperated pipe crawler  

Energy Technology Data Exchange (ETDEWEB)

In the 1950s, the Savannah River Site built an open, unlined retention basin to temporarily store potentially radionuclide contaminated cooling water from a chemical separations process and storm water drainage from a nearby waste management facility that stored large quantities of nuclear fission byproducts in carbon steel tanks. The retention basin was retired from service in 1972 when a new, lined basin was completed. In 1978, the old retention basin was excavated, backfilled with uncontaminated dirt, and covered with grass. At the same time, much of the underground process pipeline leading to the basin was abandoned. Since the closure of the retention basin, new environmental regulations require that the basin undergo further assessment to determine whether additional remediation is required. A visual and radiological inspection of the pipeline was necessary to aid in the remediation decision making process for the retention basin system. A teleoperated pipe crawler inspection system was developed to survey the abandoned sections of underground pipelines leading to the retired retention basin. This paper will describe the background to this project, the scope of the investigation, the equipment requirements, and the results of the pipeline inspection.

Detection of possible soil contaminations in abandoned sites. Guide for the gathering and evaluation of information on process-typical land contaminations in abandoned industrial and trade sites  

International Nuclear Information System (INIS)

In industrial cities and regions, the numbers and areas of abandoned sites are particularly large. The more probability of land pollution in former industrial or trade sites poses grave problems to the communities environmental protection departments, town planning departments (especially development planners) and the promotors of the municipal economy: In most cases, decontamination and renewed use of suspect areas can be tackled only after verification of whether there actually is soil or ground water contamination and after establishment of the hazards resulting from these pollutions. Gathering and evaluation of information on the history of use of such sites enables the authorities in charge to make fairly reliable first assessments of hazard potentials from abandoned sites: such information and evaluation serves as a basis for working out concepts for individual and budget-priced investigations to assess risk potentials.

Kepler Science Operations Center Pipeline Framework  

Science.gov (United States)

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

Biogeochemical behaviour and bioremediation of uranium in waters of abandoned mines.  

Science.gov (United States)

The discharges of uranium and associated radionuclides as well as heavy metals and metalloids from waste and tailing dumps in abandoned uranium mining and processing sites pose contamination risks to surface and groundwater. Although many more are being planned for nuclear energy purposes, most of the abandoned uranium mines are a legacy of uranium production that fuelled arms race during the cold war of the last century. Since the end of cold war, there have been efforts to rehabilitate the mining sites, initially, using classical remediation techniques based on high chemical and civil engineering. Recently, bioremediation technology has been sought as alternatives to the classical approach due to reasons, which include: (a) high demand of sites requiring remediation; (b) the economic implication of running and maintaining the facilities due to high energy and work force demand; and (c) the pattern and characteristics of contaminant discharges in most of the former uranium mining and processing sites prevents the use of classical methods. This review discusses risks of uranium contamination from abandoned uranium mines from the biogeochemical point of view and the potential and limitation of uranium bioremediation technique as alternative to classical approach in abandoned uranium mining and processing sites.

Planned and proposed pipeline regulations  

International Nuclear Information System (INIS)

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

Slurry pipeline technology: an overview  

Energy Technology Data Exchange (ETDEWEB)

Slurry pipelines represent an economical and environmentally friendly transportation means for many solid materials. This paper provides an over-view of the technology, its evolution and current Brazilian activity. Mineral resources are increasingly moving farther away from ports, processing plants and end use points, and slurry pipelines are an important mode of solids transport. Application guidelines are discussed. State-of-the-Art technical solutions such as pipeline system simulation, pipe materials, pumps, valves, automation, telecommunications, and construction techniques that have made the technology successful are presented. A discussion of where long distant slurry pipelines fit in a picture that also includes thickened and paste materials pipe lining is included. (author)

Pipeline dynamics subject to restraints with clearance  

International Nuclear Information System (INIS)

The principle of virtual works at its incremental form, is utilized for the formulation of flat pipeline vibration problems, of elastic-plastic behavior, submitted to restraints with clearance (also with elastic-plastic behavior) and with viscous damping. The possibility of uniform movement of the support, that simulates the seismic action is also considered. The finite element method and an integration time algorithm, are utilized for the problem resolution. Some examples ilustrate the application of the development program. (Author)

Reduction and removal of vibrations in pipeline systems  

International Nuclear Information System (INIS)

The paper refers to the problems of vibrations occurring quite frequently as cyclic loads at piping. As these vibrations basically appear at pipework, it is widely thought that the pipeline is not 'in working order'. A staged procedure is presented which aims to avoid and remove vibrations. The example given clearly shows the typical result of a vibration. Here the pipeline constitutes the resonant body while the excitation results from the internals (short venturi nozzle). (orig.)

Meanings of Consumption and Abandonment: Understanding Smoking Cessation Symbolism  

Directory of Open Access Journals (Sweden)

Full Text Available In consumption studies, very little attention has been focused on investigating abandonment and, more specifically, its symbolic dimension. The present study aims to investigate how meanings are created and negotiated through the abandonment of cigarettes. This study used a qualitative methodology to collect and analyze the data generated by one-on-one semi-structured in-depth interviews with 15 Brazilian ex-smokers. Results suggest that abandonment of cigarettes can be offered as a connection, gift, or sacrifice that makes relations special and even magical. As regards abandonment, the present study evidences the interactions and movements of positive and negative meanings related to the consumption and non-consumption of a category. The study proposes a framework that highlights the cooling, decontamination, reinforcement and defensive symbolical movements, thus constructing a tool for analyzing abandonment, offering possible paths of intervention for organizations that are interested in this issue.

API Publication 4507, Abandoned oil and gas industry wells  

International Nuclear Information System (INIS)

This paper reports on the potential for abandoned oil and gas industry wells in the Lower Tuscaloosa Sand oil-producing trend of Mississippi and Louisiana to act as conduits for flow of saline water from the Lower Tuscaloosa Sand into underground sources of drinking water. The study included correlation of the stratigraphic units throughout the Lower Tuscaloosa trend; documentation of the engineering characteristics of geologic units and abandoned wells in the trend; estimation of the thickness, porosity, and permeability of drilling mud and sloughed shale in abandoned wells in the trend; and an estimation of where corroded casing might occur in cased abandoned wells in the trend. On the basis of modeling that was performed, it was concluded that it is very unlikely that conditions would ever exist in the Lower Tuscaloosa trend where abandoned oil and gas wells would serve as conduits for movement of water into an underground source of drinking water

Diverless pipeline repair system for deep water  

Energy Technology Data Exchange (ETDEWEB)

SiRCoS (Sistema Riparazione Condotte Sottomarine) is a diverless pipeline repair system composed of a suite of tools to perform a reliable subsea pipeline repair intervention in deep and ultra deep water which has been on the ground of the long lasting experience of Eni and Saipem in designing, laying and operating deep water pipelines. The key element of SiRCoS is a Connection System comprising two end connectors and a repair spool piece to replace a damaged pipeline section. A Repair Clamp with elastomeric seals is also available for pipe local damages. The Connection System is based on pipe cold forging process, consisting in swaging the pipe inside connectors with suitable profile, by using high pressure seawater. Three swaging operations have to be performed to replace the damaged pipe length. This technology has been developed through extensive theoretical work and laboratory testing, ending in a Type Approval by DNV over pipe sizes ranging from 20 inches to 48 inches OD. A complete SiRCoS system has been realised for the Green Stream pipeline, thoroughly tested in workshop as well as in shallow water and is now ready, in the event of an emergency situation.The key functional requirements for the system are: diverless repair intervention and fully piggability after repair. Eni owns this technology and is now available to other operators under Repair Club arrangement providing stand-by repair services carried out by Saipem Energy Services. The paper gives a description of the main features of the Repair System as well as an insight into the technological developments on pipe cold forging reliability and long term duration evaluation.

Advances in riser and pipeline technologies  

Energy Technology Data Exchange (ETDEWEB)

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

Kvitebjoern gas pipeline repair - baptism of remote pipeline repair system  

Energy Technology Data Exchange (ETDEWEB)

On the 1st of November 2007, severe anchor damage was discovered on the 30 inch Kvitebjoern gas export pipeline. The damage constituted a localised dent and a 17deg buckle, but no leakage. Statoil has invested in building an effective repair contingency structure for the large pipeline network on the Norwegian Continental shelf, with particular focus on the large gas export pipelines. The repair method for the Kvitebjoern pipeline was remotely operated using two Morgrip couplings and a spool. The installation used the purpose built Pipeline Repair System stored at Killingoey and couplings produced and tested back in 2005. This presentation will cover the initial damage investigations, the temporary operational phase, the repair preparations, the actual repair and lessons learned. (Author)

A Cheap Aerial Gas Pipeline  

Directory of Open Access Journals (Sweden)

Full Text Available Problem statement: At present time gas pipelines are designed from steel and located on ground surface. That is very expensive and building requests a lot of time. Research and utilization of an old author idea: Design of new cheap aerial pipelines, a large flexible tube deployed at high altitude through neutral seas, for delivery of natural (fuel gas, water and other payload over a long distance is delineated. Approach: A lift force of 1 m3 of methane equals approximately 0.5 kg (1 pound. The lightweight film flexible pipeline can be located in air at high altitude and, as such, did not damage the environment. Using the lift force of this pipeline and wing devices payloads of oil, water, or other fluids, or even solids such as coal, cargo, passengers can be delivered cheaply at long distance. Results: Researcher showed: This aerial pipeline dramatically decreased the cost and time of construction relative to conventional pipelines of steel which saved energy and greatly lowers the capital cost of construction. Article contained a computed project for delivery 24 billion m3 of gas and tens of million tons of oil, water or other payload per year. Conclusion: Design of new cheap aerial pipelines, a large flexible tube deployed at high altitude, for delivery of natural (fuel gas, water and other payload over a long distance (neutral sea was delineated. The offered idea an aerial pipe line was researched. It was shown new pipelines radically decreased pipeline cost and construction time. Using the lift force of this pipeline and wing devices payloads of oil, water, or other fluids, or even solids such as coal, cargo, passengers can be delivered cheaply at long distance. This pipeline and wing devices also allowed to delivery the other goods.

A 12-year cavern abandonment test  

Directory of Open Access Journals (Sweden)

Full Text Available In 1997-1998, an abandonment test was performed in a 950-m deep, 8000-m3 salt cavern operated by GDF SUEZ at Etrez, France. In this relatively small brine-filled cavern, which had been kept idle for 15 years before the test, thermal equilibrium was reached. A special system was designed to monitor leaks, which proved to be exceedingly small. In these conditions, brine permeation and cavern creep closure are the only factors to play significant roles in pressure evolution. This test strongly suggested that obtaining an equilibrium pressure such that the effects of these two factors were exactly equal would be reached in the long term. Four years later, pressure monitoring in the closed cavern resumed. Pressure evolution during the 2002-2009 period confirmed that cavern brine pressure will remain constant and significantly smaller than geostatic pressure in the long term, precluding any risk of fracturing and brine seepage to the overburden layers.

Suspension, abandonment, decontamination, and surface land reclamation of upstream oil and gas facilities : informational letter IL 98-2  

International Nuclear Information System (INIS)

This release of the Alberta Energy and Utilities Board (EUB) is intended to clarify the jurisdictional roles of Alberta Environmental Protection (AEP) and the EUB with regard to their respective responsibilities for the regulation of the suspension, abandonment, decontamination and surface land reclamation of active and inactive upstream oil and gas facilities. The EUB, AEP and industrial operators all have separate roles and responsibilities when active and inactive upstream facilities are suspended or reclaimed. In the future, industry operators will have more interaction with the AEP during the decontamination of a site, while the EUB will concentrate on pollution prevention and abandonment of non-economic facilities. All oilfield waste generated from suspension, abandonment, decontamination, and surface land reclamation of an active or inactive upstream oil and gas facility will fall under the jurisdiction of the EUB. Contaminated soils, sludges, and waters that are physically removed as a result of decontamination activities are considered to be oilfield wastes. The regulatory responsibility between the AEP and the EUB remains unchanged for the reclamation process of on-lease and off-lease spills, releases or pipeline breaks. Industry operators are no longer allowed to discharge any produced liquid to earthen pits or ponds and are encouraged to reclaim existing ones. 3 figs

Also deputies will say something to new pipeline of Slovnaft  

International Nuclear Information System (INIS)

The oil transit company, Transpetrol, expects the new Bratislava-Schwechat pipeline connecting the OMV refinery to the Druzba pipeline to increase the use of the pipeline and improve company revenues by 20%. The Austrian project partner, OMV, looks to the project to decrease transportation costs for Russian oil. One sixth of the 60 km pipeline will be built in Slovakia, but there is a problem - the Slovak Ministry of Environment and the City of Bratislava have not approved the route proposed by Transpetrol. In their opinion, the propose route would endanger the protected area, Zitny ostrov, that provides drinking water to the capital. Slovnaft also plans a new pipeline to replace the old obsolete one used to transport its products to the mineral oils transhipment centre at Bratislava docks. One of the alternatives proposed by Slovnaft is the construction of a pipeline and transhipment centre on Zitny ostrov. Unlike the Transpetrol project, this has already received approval from the Ministry of Environment. Before construction work on the pipeline to Schwechat can start. OMV will have resolve issues related to the supply of oil from Russia. According to the original plans, Yukos, which owns a 49% stake in Transpetrol, was to supply the oil. But due to tax problems in Russia, Yukos lost its main drilling division, Juganskneftgaz

Experience with two pipeline river crossings in Argentina  

Energy Technology Data Exchange (ETDEWEB)

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)

INTERNAL REPAIR OF PIPELINES  

Energy Technology Data Exchange (ETDEWEB)

The two broad categories of fiber-reinforced composite liner repair and deposited weld metal repair technologies were reviewed and evaluated for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Principal conclusions from a survey of natural gas transmission industry pipeline operators can be summarized in terms of the following performance requirements for internal repair: (1) Use of internal repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling when a new bore must be created to solve a leak or other problem. (3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) The most common size range for 80% to 90% of operators surveyed is 508 mm (20 in.) to 762 mm (30 in.), with 95% using 558.8 mm (22 in.) pipe. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without liners, indicating that this type of liner is only marginally effective at restoring the pressure containing capabilities of pipelines. Failure pressures for larger diameter pipe repaired with a semi-circular patch of carbon fiber-reinforced composite lines were also marginally greater than that of a pipe section with un-repaired simulated damage without a liner. These results indicate that fiber reinforced composite liners have the potential to increase the burst pressure of pipe sections with external damage Carbon fiber based liners are viewed as more promising than glass fiber based liners because of the potential for more closely matching the mechanical properties of steel. Pipe repaired with weld deposition failed at pressures lower than that of un-repaired pipe in both the virgin and damaged conditions, indicating that this repair technology is less effective at restoring the pressure containing capability of pipe than a carbon fiber-reinforced liner repair. Physical testing indicates that carbon fiber-reinforced liner repair is the most promising technology evaluated to-date. The first round of optimization and validation activities for carbon-fiber repairs are complete. Development of a comprehensive test plan for this process is recommended for use in the field trial portion of this program.

INTERNAL REPAIR OF PIPELINES  

Energy Technology Data Exchange (ETDEWEB)

The two broad categories of deposited weld metal repair and fiber-reinforced composite liner repair technologies were reviewed for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Preliminary test programs were developed for both deposited weld metal repair and for fiber-reinforced composite liner repair. Evaluation trials have been conducted using a modified fiber-reinforced composite liner provided by RolaTube and pipe sections without liners. All pipe section specimens failed in areas of simulated damage. Pipe sections containing fiber-reinforced composite liners failed at pressures marginally greater than the pipe sections without liners. The next step is to evaluate a liner material with a modulus of elasticity approximately 95% of the modulus of elasticity for steel. Preliminary welding parameters were developed for deposited weld metal repair in preparation of the receipt of Pacific Gas & Electric's internal pipeline welding repair system (that was designed specifically for 559 mm (22 in.) diameter pipe) and the receipt of 559 mm (22 in.) pipe sections from Panhandle Eastern. The next steps are to transfer welding parameters to the PG&E system and to pressure test repaired pipe sections to failure. A survey of pipeline operators was conducted to better understand the needs and performance requirements of the natural gas transmission industry regarding internal repair. Completed surveys contained the following principal conclusions: (1) Use of internal weld repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling (HDD) when a new bore must be created to solve a leak or other problem. (3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) Pipe diameter sizes range from 50.8 mm (2 in.) through 1,219.2 mm (48 in.). The most common size range for 80% to 90% of operators surveyed is 508 mm to 762 mm (20 in. to 30 in.), with 95% using 558.8 mm (22 in.) pipe. An evaluation of potential repair methods clearly indicates that the project should continue to focus on the development of a repair process involving the use of GMAW welding and on the development of a repair process involving the use of fiber-reinforced composite liners.

(3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) The most common size range for 80% to 90% of operators surveyed is 508 mm (20 in.) to 762 mm (30 in.), with 95% using 558.8 mm (22 in.) pipe. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without liners, indicating that this type of liner is only marginally effective at restoring the pressure containing capabilities of pipelines. Failure pressures for larger diameter pipe repaired with a semi-circular patch of carbon fiber-reinforced composite lines were also marginally greater than that of a pipe section with un-repaired simulated damage without a liner. These results indicate that fiber reinforced composite liners have the potential to increase the burst pressure of pipe sections with external damage Carbon fiber based liners are viewed as more promising than glass fiber based liners because of the potential for more closely matching the mechanical properties of steel. Pipe repaired with weld deposition failed at pressures lower than that of un-repaired pipe in both the virgin and damaged conditions, indicating that this repair technology is less effective at restoring the pressure containing capability of pipe than a carbon fiber-reinforced liner repair. Physical testing indicates that carbon fiber-reinforced liner repair is the most promising technology evaluated to-date. Development of a comprehensive test plan for this process is recommended for use in the field trial portion of this program.

The LOFAR Transients Pipeline  

CERN Document Server

Current and future astronomical survey facilities provide a remarkably rich opportunity for transient astronomy, combining unprecedented fields of view with high sensitivity and the ability to access previously unexplored wavelength regimes. This is particularly true of LOFAR, a recently-commissioned, low-frequency radio interferometer, based in the Netherlands and with stations across Europe. The identification of and response to transients is one of LOFAR's key science goals. However, the large data volumes which LOFAR produces, combined with the scientific requirement for rapid response, make automation essential. To support this, we have developed the LOFAR Transients Pipeline, or TraP. The TraP ingests multi-frequency image data from LOFAR or other instruments and searches it for transients and variables, providing automatic alerts of significant detections and populating a lightcurve database for further analysis by astronomers. Here, we discuss the scientific goals of the TraP and how it has been desig...

Experience of the construction of the main circulating circuit pipelines  

International Nuclear Information System (INIS)

The construction technology of the WWER-1000(e) reactor main circulating circuit (MCC), pipelines is described. The MCC pipelines link the main components of the NPP primary coolant circuit: the reactor, steam generators and main circulating pumps. Basic technical parameters of the pipelines for NPP with the WWER-440 and WWER-1000 reactors are presented. The works on the assemblying, erection and welding of the pipelines were carried out during a year, and their labour costs are evaluated as 17600 man- days. The validity of basic technological solutions has been proved. Elongation of the reactor nozzles, simplification of the thermal treatment technology and welding automation are pointed out as practical possible means to lower the labour costs of the construction

Pipeline flow of heavy oil with temperature-dependent viscosity  

Energy Technology Data Exchange (ETDEWEB)

The heavy oil produced offshore needs to be transported through pipelines between different facilities. The pipelines are usually laid down on the seabed and are submitted to low temperatures. Although heavy oils usually present Newtonian behavior, its viscosity is a strong function of temperature. Therefore, the prediction of pressure drops along the pipelines should include the solution of the energy equation and the dependence of viscosity to temperature. In this work, an asymptotic model is developed to study this problem. The flow is considered laminar and the viscosity varies exponentially with temperature. The model includes one-dimensional equations for the temperature and pressure distribution along the pipeline at a prescribed flow rate. The solution of the coupled differential equation is obtained by second-order finite difference. Results show a nonlinear behavior as a result of coupled interaction between the velocity, temperature, and temperature dependent material properties. (author)

Pipelining and bypassing in a RISC/DSP processor  

Science.gov (United States)

This paper proposes pipelining and bypassing unit (BPU) design method in our 32-bit RISC/DSP processor: MediaDsp3201 (briefly, MD32). MD32 is realized in 0.18?m technology, 1.8v, 200MHz working clock and can achieve 200 million/s Multiply-Accumulate (MAC) operations. It merges RISC architecture and DSP computation capability thoroughly, achieves fundamental RISC, extended DSP and single instruction multiple data (SIMD) instruction set with various addressing modes in a unified and customized DSP pipeline stage architecture. We will first describe the pipeline structure of MD32, comparing it to typical RISC-style pipeline structure. And then we will study the validity of two bypassing schemes in terms of their effectiveness in resolving pipeline data hazards: Centralized and Distributed BPU design strategy (CBPU and DBPU). A bypassing circuit chain model is given for DBPU, which register read is only placed at ID pipe stage. Considering the processor"s working clock which is decided by the pipeline time delay, the optimization of circuit that serial select with priority is also analyzed in detail since the BPU consists of a long serial path for combination logic. Finally, the performance improvement is analyzed.

Estimating Limits for the Geothermal Energy Potential of Abandoned Underground Coal Mines: A Simple Methodology  

Directory of Open Access Journals (Sweden)

Full Text Available Flooded mine workings have good potential as low-enthalpy geothermal resources, which could be used for heating and cooling purposes, thus making use of the mines long after mining activity itself ceases. It would be useful to estimate the scale of the geothermal potential represented by abandoned and flooded underground mines in Europe. From a few practical considerations, a procedure has been developed for assessing the geothermal energy potential of abandoned underground coal mines, as well as for quantifying the reduction in CO2 emissions associated with using the mines instead of conventional heating/cooling technologies. On this basis the authors have been able to estimate that the geothermal energy available from underground coal mines in Europe is on the order of several thousand megawatts thermal. Although this is a gross value, it can be considered a minimum, which in itself vindicates all efforts to investigate harnessing it.

Saint John lateral pipeline project: comprehensive study report  

International Nuclear Information System (INIS)

A descripion is given of the results of an environmental impact assessment of the construction of a natural gas pipeline that will bring gas from Maritimes and Northeast Pipeline Management Ltd.'s (M and NP) main transmission pipeline to clients in Lake Utopia and Saint John, NB. It will be 110 km long, and the Saint John lateral will join the mainline approximately 2 km south of Big Kedron Lake, NB. Various institutional, industrial, commercial and residential clients will be able to access the pipeline in the future, and it is intended to be capable of future expansion for markets along its route and for markets that become economically feasible in the future. A matrix was developed that relates environmental resources to Environmental Components of Concern (ECCs), and to the rationale for exclusion/inclusion of the ECC as a Valued Environmental Component (VECs). The positive benefits of the pipeline to clients in the Saint John area include: reduced dependence on foreign oil, fuel switching and price competition, lower air emission pollution, increased energy efficiency, and a source of energy that is secure and reliable. VECs were selected based on: concerns of various stakeholders including the public, community groups, scientific parties, Aboriginal groups, government officials and agencies, relevant regulations; relevant literature; and past evaluation experiences, including future developments of the proposed study area. Further selection of the VECs required a. Further selection of the VECs required an examination of the issues picked out via scoping to determine the ways in which the overall project could affect the ECCs, and included construction, operation, decommissioning/abandonment, malfunctions and accidents of the pipeline. The phases of the project as they impacted residually and cumulatively on the VECs were evaluated, and impacts on Valued Socio-Economic Components (VSCs) were assessed also. The mitigation efforts taken will minimize the potential effects of the project on VECs and VSCs. For all of the project phases it is expected that residual effects will be without significance as will be the overall environmental impact. 29 refs

Natural gas pipeline technology overview.  

Energy Technology Data Exchange (ETDEWEB)

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 transmission companies. Compressor stations at required distances boost the pressure that is lost through friction as the gas moves through the steel pipes (EPA 2000). The natural gas system is generally described in terms of production, processing and purification, transmission and storage, and distribution (NaturalGas.org 2004b). Figure 1.1-2 shows a schematic of the system through transmission. This report focuses on the transmission pipeline, compressor stations, and city gates.

Regulating natural gas pipeline efficiency  

International Nuclear Information System (INIS)

Proponents of gas pipeline capacity assignment---sometimes referred to as capacity brokering---would like a policy that would allow holders of gas pipeline capacity contact, usually firm transportation, to resell that capacity for short periods of time when it is not needed. In this paper the authors review the current U.S. policy towards capacity assignment in the context of FERC regulation of interstate pipelines and compare the U.S. debate with Canada's approach. The authors offer a modest proposal to institute a capacity assignment program experiment

RUSSIA AND ITS PIPELINE WEAPON  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper we intend to present the new power which is given to Russia upon EU due to her great natural resources and due to her control upon pipelines. Now Moscow can exert influence upon countries in Europe not through its revolutionary zeal and its tanks and army, but through its resources. And she knows how to use them and how make the EU dependent on her will: this is a new geopolitics, a 21-th century geopolitics, which is centered upon the control of gas pipelines in Central Asian states and upon EU states great dependence on Russian pipeline system.

Black powder in gas pipelines  

Energy Technology Data Exchange (ETDEWEB)

Despite its common occurrence in the gas industry, black powder is a problem that is not well understood across the industry, in terms of its chemical and physical properties, source, formation, prevention or management of its impacts. In order to prevent or effectively manage the impacts of black powder, it is essential to have knowledge of its chemical and physical properties, formation mechanisms and sources. The present paper is divided into three parts. The first part of this paper is a synopsis of published literature. The second part reviews the recent laboratory and field work conducted at Saudi Aramco Research and Development Center to determine the compositions, properties, sources and formation mechanisms of black powder in gas transmission systems. Microhardness, nano-indentation, X-ray Diffraction (XRD), X-ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM) techniques were used to analyze a large number of black powder samples collected from the field. Our findings showed that black powder is generated inside pipelines due to internal corrosion and that the composition of black powder is dependent on the composition of transported gas. The final part presents a summary and brief discussion of various black powder management methods. (author)

Electrometrical Methods Application for Detection of Heating System Pipeline Corrosion  

Science.gov (United States)

Coated steel underground pipelines are widely used for the petroleum and gaze transportation, for the water and heat supply. The soils, where the pipelines are placed, are usually highly corrosive for pipe's metal. In the places of crippling of external coating the corrosion processes begin, and this can provoke a pipe breakage. To ensure the pipeline survivability it is necessary to carry out the control of pipeline conditions. The geophysical methods are used to provide such diagnostic. Authors have studied the corrosion processes of the municipal heating system pipelines in Saint-Petersburg (Russia) using the air thermal imaging method, the investigation of electromagnetic fields and spontaneous polarization, measurements of electrode potentials of metal tubes. The pipeline reparation works, which have been provided this year, allowed us to make the visual observation of pipes. The investigation object comprises a pipeline composed of two parallel tubes, which are placed 1-2 meters deep. The fact that the Russian Federation and CIS countries still use the direct heat supply system makes impossible any addition of anticorrosion components to circulating water. Pipelines operate under high pressure (up to 5 atm) and high temperature (designed temperature is 150°C). Tube's isolation is meant for heat loss minimization, and ordinary has poor hydro-isolation. Some pipeline construction elements (sliding and fixed bearings, pressure compensators, heat enclosures) are often non-isolated, and tube's metal contacts with soil. Hard usage condition, ingress of technical contamination cause, stray currents etc. cause high accidental rate. Realization of geophysical diagnostics, including electrometry, is hampered in a city by underground communication systems, power lines, isolating ground cover (asphalt), limitation of the working area with buildings. These restrictions form the investigation conditions. In order to detect and localize isolation (coat) defects authors successfully use the excitation-at-the-mass method measurement together with the measurements of magnetic and electrical components of electromagnetic field. However, the electrical contact between a tube and the soil, as well as the presence of zones of isolation defects is not the direct indicators of corrosion focus places. Authors use the spontaneous polarization method to investigate electrical fields, caused by natural electromotive forces of electrochemical origin. Different types of EM and SP anomalies have been detected. After statistical study and visual observations of extracted pipes, the relations between such anomalies and pipeline condition have been obtained. The places of underground pipeline coat destruction can be specified by complex of geophysical investigations. Also, it is possible to detect the intensity of destruction and corrosion processes in real time.

The Kepler Science Operations Center Pipeline Framework Extensions  

Science.gov (United States)

The Kepler Science Operations Center (SOC) is responsible for several aspects of the Kepler Mission, including managing targets, generating on-board data compression tables, monitoring photometer health and status, processing the science data, and exporting the pipeline products to the mission archive. We describe how the generic pipeline framework software developed for Kepler is extended to achieve these goals, including pipeline configurations for processing science data and other support roles, and custom unit of work generators that control how the Kepler data are partitioned and distributed across the computing cluster. We describe the interface between the Java software that manages the retrieval and storage of the data for a given unit of work and the MATLAB algorithms that process these data. The data for each unit of work are packaged into a single file that contains everything needed by the science algorithms, allowing these files to be used to debug and evolve the algorithms offline.

Review of procedures for welding onto pressurized pipelines  

Energy Technology Data Exchange (ETDEWEB)

The welding of attachments into pressurized pipelines and storage vessels (referred to as hot tapping) is a necessary and common operation in the transmission industry. Care must be exercised to choose a welding procedure that can reduce the risk of burn through and the formation of very high hardness levels in the heat-affected zone (HAZ) that can lead to a higher than normal risk of cracking. A state of the art review of hot tap welding on pressurized pipelines has been undertaken. All open literature pertinent to hot tap welding has been examined, cataloged and areas requiring further work identified. A large volume of literature exists for welding on pressurized pipelines but the majority consists of successful accounts of repair work on specific items, rather than any generalized approach. The methods, controls and results of work from industry accounts very widely. No known national standard exists and industry standards vary considerably. 26 refs., 3 figs.

Natural Gas pipelines: economics of incremental capacity  

International Nuclear Information System (INIS)

A number of gas transmission pipeline systems in Australia exhibit capacity constraints, and yet there is little evidence of creative or innovative processes from either the service provides of the regulators which might provide a market-based response to these constraints. There is no provision in the Code in its current form to allow it to accommodate these processes. This aspect is one of many that require review to make the Code work. It is unlikely that the current members of the National Gas Pipeline Advisory Committee (NGPAC) or its advisers have sufficient understanding of the analysis of risk and the consequential commercial drivers to implement the necessary changes. As a result, the Code will increasingly lose touch with the commercial realities of the energy market and will continue to inhibit investment in new and expanded infrastructure where market risk is present. The recent report prepared for the Business Council of Australia indicates a need to re-vitalise the energy reform process. It is important for the Australian energy industry to provide leadership and advice to governments to continue the process of reform, and, in particular, to amend the Code to make it more relevant. These amendments must include a mechanism by which price signals can be generated to provide timely and effective information for existing service providers or new entrants to install incremental pipeline capacity

International Nuclear Information System (INIS)

The contribution describes procedural aspects of fatigue analyses and the influencing parameters to be considered. Experimental analyses involve real components or big test pieces, and relevant influencing parameters like the type of stress, component shape and material characteristics are directly taken into account. In theoretical analyses, global or local concepts are applied. In the case of global concepts, relevant influencing parameters are considered already in the calculation of the Woehler curve which is obtained using large-scale test pieces. As it may be quite time-consuming to calculate these curves, global concepts are used preferably for components of simple geometry that are produced in large numbers. In the case of local concepts, Woehler curves are used which are obtained from simple test pieces, and the various influencing parameters (load type, medium, surface, geometry, etc.) are considered. In concrete applications, the test procedure is specified as a function of the state of knowledge on loads and influencing parameters and in consideration of safety and economic efficiency requirements. In nuclear power plant pipelines and vessels, fatigue strength in operation is influenced by real loads, real stress cycles and the surrounding medium. As it is impossible to specify local loads both in normal and abnormal operation, these must be monitored during operation if higher safety requirements apply. (orig.)

Abandoned floodplain plant communities along a regulated dryland river  

Science.gov (United States)

Rivers and their floodplains worldwide have changed dramatically over the last century because of regulation by dams, flow diversions and channel stabilization. Floodplains no longer inundated by river flows following dam-induced flood reduction comprise large areas of bottomland habitat, but the effects of abandonment on plant communities are not well understood. Using a hydraulic flow model, geomorphic mapping and field surveys, we addressed the following questions along the Bill Williams River, Arizona: (i) What per cent of the bottomland do abandoned floodplains comprise? and (ii) Are abandoned floodplains quantitatively different from adjacent xeric and riparian surfaces in terms of vegetation composition and surface sediment? We found that nearly 70% of active channel and floodplain area was abandoned following dam installation. Abandoned floodplains along the Bill Williams River tend to be similar to each other yet distinct from neighbouring habitats: they have been altered physically from their historic state, leading to distinct combinations of surface sediments, hydrology and plant communities. Abandoned floodplains may transition to xeric communities over time but are likely to retain some riparian qualities as long as there is access to relatively shallow ground water. With expected increases in water demand and drying climatic conditions in many regions, these surfaces and associated vegetation will continue to be extensive in riparian landscapes worldwide

Groundwater flow modelling of an abandoned partially open repository  

Energy Technology Data Exchange (ETDEWEB)

As a part of the license application, according to the nuclear activities act, for a final repository for spent nuclear fuel at Forsmark, the Swedish Nuclear Fuel and Waste Management Company (SKB) has undertaken a series of groundwater flow modelling studies. These represent time periods with different hydraulic conditions and the simulations carried out contribute to the overall evaluation of the repository design and long-term radiological safety. The modelling study presented here serves as an input for analyses of so-called future human actions that may affect the repository. The objective of the work was to investigate the hydraulic influence of an abandoned partially open repository. The intention was to illustrate a pessimistic scenario of the effect of open tunnels in comparison to the reference closure of the repository. The effects of open tunnels were studied for two situations with different boundary conditions: A 'temperate' case with present-day boundary conditions and a generic future 'glacial' case with an ice sheet covering the repository. The results were summarized in the form of analyses of flow in and out from open tunnels, the effect on hydraulic head and flow in the surrounding rock volume, and transport performance measures of flow paths from the repository to surface

Geothermal Well Site Restoration and Plug and Abandonment of Wells  

Energy Technology Data Exchange (ETDEWEB)

A report is presented on the final phase of an energy research program conducted by the U.S. Department of Energy (DOE) involving two geothermal well sites in the State of Louisiana-the Gladys McCall site and the Willis Hulin site. The research program was intended to improve geothermal technology and to determine the efficacy of producing electricity commercially from geopressured resource sites. The final phase of the program consisted of plug and abandonment (P&A) of the wells and restoration of the well sites. Restoration involved (a) initial soil and water sampling and analysis; (b) removal and disposal of well pads, concrete, utility poles, and trash; (c) plugging of monitor and freshwater wells; and (d) site leveling and general cleanup. Restoration of the McCall site required removal of naturally occurring radioactive material (NORM), which was costly and time-consuming. Exhibits are included that provide copies of work permits and authorizations, P&A reports and procedures, daily workover and current conditions report, and cost and salvage reports. Site locations, grid maps, and photographs are provided.

Pipeline coating inspection in Mexico applying surface electromagnetic technology  

Energy Technology Data Exchange (ETDEWEB)

The main problems in the pipeline systems in Mexico include: extremely aggressive soil characterized by a high clay content and low resistivity, interconnection between several pipes, including electrical contacts of active pipelines with out of service pipes, and short distances between pipes in comparison with their depths which reduce the resolution of coating inspection. The results presented in this work show the efficiency of the Surface Electromagnetic Pipeline Inspection (SEMPI) technology to determine the technical condition of pipelines in situations before mentioned. The SEMPI technology includes two stages: regional and detailed measurements. The regional stage consists of magnetic field measurements along the pipeline using large distances (10 - 100 m) between observation points to delimit zones with damaged coating. For quantitative assessing the leakage and coating resistances along pipeline, additional measurements of voltage and soil resistivity measurements are performed. The second stage includes detailed measurements of the electric field on the pipe intervals with anomalous technical conditions identified in the regional stage. Based on the distribution of the coating electric resistance and the subsoil resistivity values, the delimitation of the zones with different grade of coating quality and soil aggressiveness are performed.

Solving an unpiggable pipeline challenge  

Energy Technology Data Exchange (ETDEWEB)

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.

Technical development concerning abandonment of low level radioactive wastes into ocean  

International Nuclear Information System (INIS)

The amount of radioactive wastes generated in nuclear power stations has increased year by year, and the measures to treat and dispose them safely and surely have become urgent problem. In October, 1976, the Atomic Energy Commission presented the basic policy with ''On the countermeasures to radioactive wastes'', and the necessity of establishing a corporation undertaking the execution of trial disposal was mentioned. The foundation ''Atomic Energy Environment Conditioning Center'' was established accordingly, and it is making the preparation of the required tests and researches and the trial disposal in ocean. Four sea areas were selected as the possible areas for the disposal in ocean, and the survey on the environment of these sea areas was carried out for three years. Since 1977, the detailed survey has been made about the B sea area which seemed to be most desirable. In order to execute the trial disposal in ocean safely and surely, the soundness of solidified bodies, the preparation of a ship for abandonment, the works of transport and abandonment, and the pressurizing test of the drums for abandonment in a high pressure tank were studied. The survey of four sea areas and the evaluation of safety in ocean environment are described. The relevant laws were revised so as to accord with international treaties. The international relations concerning this problem are explained. (Kako, I.)

Full Text Available The article provides the information on a promising technology for trenchless repair named Swagelining, which supposes pulling into the old pipeline the new polymer with its preliminary thermo-mechanical compression and further straightening. The coauthors present the results of the calculations determining the thickness of the polyethylene pipes after compression and straightening in the old pipeline depending on the initial diameter in case of different ratio of the diameter to the wall thickness (SDR and the dynamics of the changes in hydraulic performance after repair work on the pipeline using the method Swagelining. The concept of the energy saving potential is formed in addition to a no-dig repair for pressure piping systems, water supply, and its magnitude. On the basis of the research results, the authors formulate the principles of the energy efficiency potential after the implementation of the trenchless technology of drawing the old pipeline with new polymer pipes with their preliminary thermo-mechanical compression and subsequent area enlargement. The technology Swagelining is described and the authors develop a mathematical model that illustrates the behavior of the pipeline in the process of shrink operations. Such parameters are analyzed as changing the diameter of the pipeline at thermo-mechanical compression, the hydraulic parameters of the new (polymer and old (steel pipelines, energy savings on one-meter length of the pipeline. The calculated values of the electric power economy on the whole length of the pipeline repair section with a corresponding flow of transported waters.The characteristics and capabilities of the technology of trenchless renovation Swagelining allows achieving simultaneously the effect of resource saving (eliminationof the defects and, as a consequence, of water leakage and energy saving (reduction in the water transportation cost.A numerical example of the old steel pipeline renovation shows the calculated data, which proves the efficiency of the considered technology. The calculation results can be used as base material for designers when selecting the final decision of the alternative at reconstruction of dilapidated pipelines by Swagelining using a wide range of polymer pipes with the corresponding value of the SDR.

Long-Term Forest Dynamics and Land-Use Abandonment in the Mediterranean Mountains, Corsica, France  

Directory of Open Access Journals (Sweden)

Full Text Available Human practices have had an impact on Mediterranean ecosystems for millennia, particularly through agricultural and pastoral activities. Since the mid-19th century, land-use abandonment has led to the expansion of shrubland and forest, especially in the mountainous areas of the northern Mediterranean basin. Knowledge of these factors is vital to understanding present forest patterns and predicting future forest dynamics in the Mediterranean mountains. We aimed to analyze and understand how land-use abandonment affected spatial modifications of landscapes in two study areas, 44,000 ha and 60,000 ha, located on the island of Corsica, France, representing a typical Mediterranean environment with chestnut forests. Our approach used land-cover archive documents from 1774, 1913, 1975, and 2000, and human population history, 1770 to present day, to describe landscape patterns following land-use abandonment. This research showed that dramatic changes in landscape at the two study areas were caused by the suspension of human influence and the interruption of traditional farming practices. Over the study period, both study sites showed significant reforestation of shrubland and cultivated areas marked by the presence of Quercus ilex forests (+3.40% yr-1 between 1975 and 2000 and by Pinus pinaster (+3.00% yr-1 between 1975 and 2000 at one study site that had experienced heavy rural exodus. At the same time, areas containing chestnut forests decreased by 50% between 1774 and 2000 (-0.09% yr-1 between 1774 and 1975 and -1.42% yr-1 between 1975 and 2000. Shrubland expansion remained limited at both study sites. Our study highlights the value of small-scale approaches for understanding the ecological consequences of land-use abandonment and present and future land-management decisions. Discussion concludes on the importance of working with long-term series for studies on resilience in social-ecological systems and on the consequences in terms of provision of ecosystem services.

Investigation of CO2 release pressures in pipeline cracks  

Science.gov (United States)

The CCS (Carbon Capture and Storage) technology can prevent or reduce the emissions of carbon dioxide. The main idea of this technology is the segregation and collection of CO2 from facilities with a high emission of that greenhouse gas, i.e. power plants which burn fossil fuels. To segregate CO2 from the exhaust gas the power plant must be upgraded. Up to now there are three possible procedures to segregate the carbon dioxide with different advantages and disadvantages. After segregation the carbon dioxide will be transported by pipeline to a subsurface storage location. As CO2 is at normal conditions (1013,25 Pa; 20 °C) in a gaseous phase state it must be set under high pressure to enter denser phase states to make a more efficient pipeline transport possible. Normally the carbon dioxide is set into the liquid or supercritical phase state by compressor stations which compress the gas up to 15 MPa. The pressure drop makes booster stations along the pipeline necessary which keep the CO2 in a dens phase state. Depending on the compression pressure CO2 can be transported over 300km without any booster station. The goal of this work is the investigation of release pressures in pipeline cracks. The high pressurised pipeline system consists of different parts with different failure probabilities. In most cases corrosion or obsolescence is the reason for pipeline damages. In case of a crack CO2 will escape from the pipeline and disperse into the atmosphere. Due to its nature CO2 can remain unattended for a long time. There are some studies of the CO2 dispersion process, e.g. Mazzoldi et al. (2007, 2008 and 2011) and Wang et al. (2008), but with different assumptions concerning the pipeline release pressures. To give an idea of realistic release pressures investigations with the CFD tool OpenFOAM were carried out and are presented within this work. To cover such a scenario with an accidental release of carbon dioxide a pipeline section with different diameters and leakage release holes were modelled. This pipeline section is 10m long with the leakage hole in the middle. Additionally a small environment subdomain is simulated around the crack. For computation a multiphase solver was utilised. In a first step incompressible and isothermal fluids with no phase change were assumed.

Seismic damage estimation for buried pipelines - challenges after three decades of progress  

Energy Technology Data Exchange (ETDEWEB)

This paper analyzes the evolution over the past three decades of seismic damage estimation for buried pipelines and identifies some challenges for future research studies on the subject. The first section of this paper presents a chronological description of the evolution since the mid-1970s of pipeline fragility relations - the most common tool for pipeline damage estimation - and follows with a careful analysis of the use of several ground motion parameters as pipeline damage indicators. In the second section of the paper, four gaps on the subject are identified and proposed as challenges for future research studies. The main conclusion of this work is that enhanced fragility relations must be developed for improving pipeline damage estimation, which must consider relevant parameters that could influence the seismic response of pipelines.

The effect of chestnut coppice forests abandon on slope stability: a case study  

Science.gov (United States)

Sweet chestnut has been fundamental for Italian mountainous economies for many centuries. This kind of forest was traditionally managed by coppicing in shortly rotation (15-20 years) to rapidly produce wood biomass until half of XX century. In the last decades these forests were in large part abandoned due to change in economy which made coppiced forest management unprofitable, especially in steeper slopes and where forest viability is scarce. As a consequence most of them are over aged and very dense, leading to an observed increasing in localized slope instability, primary because of the uprooting of stools (Vogt et al., 2006). In this work the effect of the abandon of chestnut coppice on slope stability was analyzed, focusing on shallow landslides triggering. The mechanical contribution to soil shear strength of differently managed chestnut stand was estimated and compared in terms of additional root cohesion. The study area is located in the Valcuvia Valley (Lombardy Prealps - Northern Italy) at an elevation about 600 m a.s.l., where two different stands, one managed and the other abandoned (over 40 year aged), were chosen. The two sampling stands are on cohesionless slopes (quaternary moraine deposits) and are homogeneous with regard to the substrate, exposure and elevation. Slope steepness influences heavily forestry practices and steeper stands are more frequently abandoned than stands on gentler terrain: in fact in the abandoned coppice the slope was higher (35 degrees against 13 in the managed stand) and no stands completely homogeneous can be found. In each site the main characteristics of the stand were surveyed and a trench in each stand was excavated to analyze root diameter and number distribution with depth; root specimens were also collected for the tensile force determination through laboratory tensile tests. Root distribution and force were then used to estimate root cohesion values through a Fiber Boundle Model (Pollen and Simon, 2005). Results, as expected, show that management didn't affect root mechanical properties, whereas root distribution within the soil profile did. In terms of additional root cohesion, values are higher in the managed stand, and lower in the abandoned one, at least in the first 50 cm of soil. In the abandoned stand, in fact, roots reach deeper layers of soil (100 cm) than the managed one (50 cm), mainly because of an unexpected greater soil depth. To assess the implication of such results in terms of slope stability, a simple infinite slope model was applied to the two conditions. The results showed that the abandoned stand is prone to instability also with a low level of saturation. On the contrary, by applying the additional root cohesion profile obtained in the managed stand to the steeper slopes, stability should be guaranteed, except in the case of total saturation. In conclusion, although more investigations are required especially to extend the number of stands, coppicing practice seem to be fundamental to prevent shallow landsliding in sweet chestnut forests over cohesionless slopes.

Location class change impact on onshore gas pipelines  

Energy Technology Data Exchange (ETDEWEB)

During a pipeline life cycle, some significant changes in the population may happen along its route. Such changes are indirectly evaluated by the increase in the amount of buildings constructed along the route, which determines the so called Location Class. Such changes, after licensing, provoke differences between what is required by the standards and what is actually done. This work has two goals. One is to study the requirements of international standards and legislations as well as some solutions used in the United States, Canada, United Kingdom and Netherlands. This goal intends to provide some technical bases for a comparative analysis on how the location class changes, during the life cycle of a pipeline, are treated in each country. Another goal is to present a risk-based methodology for the guideline development which can be used in decision-making concerning what to do in case of any location class change. Particularly, it has given special attention to the requirements which are imposed for the pipeline operational license continuation. This work is of supreme importance for the Brazilian pipeline segment, since the existing Brazilian design standard, ABNT NBR12712 for transmission and distribution pipeline design, does not deal with that issue. Moreover, a summary of the main solutions found in those countries together with a guideline, customized for the Brazilian reality, is presented. (author)

New territory for NGL pipelines  

International Nuclear Information System (INIS)

Even though the NGL pipeline industry appears mature, new geographic territory exists for expansion of NGL pipelines. However, the most fertile territory that must be pursued is the collective opportunities to better link the existing NGL industry. Associations like the Gas Processors Association can not perform the role demanded by a need to share information between the links of the chain on a more real time basis. The Association can not substitute for picking up the phone or calling a meeting of industry participants to discuss proposed changes in policies and procedures. All stakeholders must participate in squeezing out the inefficiencies of the industry. Some expansion and extension of NGL pipelines will occur in the future without ownership participation or commitments from the supply and demand businesses. However, significant expansions linking new supply sources and demand markets will only be made as the supply and demand businesses share long-term strategies and help define the pipeline opportunity. The successful industries of the twenty-first century will not be dominated by a single profitable sector, but rather by those industries which foster cooperation as well as competition. A healthy NGL industry will be comprised of profitable supply businesses and profitable demand businesses, linked together by profitable pipeline businesses

Pipeline fixings for pipelines in nuclear power stations  

International Nuclear Information System (INIS)

The pipelines run at a distance from a concrete wall. Frame type steel constructions made of U-section profiled rods which can be loaded in the elastic range act as pipeline fixings. They are fixed, in turn, via their free ends to steel supports which can be subjected to plastic deformation, which are themselves connected to the concrete wall via supports. The distance between the steel supports and the concrete wall must be such that it is greater than the maximum expected deformation of the steel supports. This achieves dumping of the load peaks for pipework fracture forces in all directions in the concrete wall. (DG)

Seasonal energy storage using bioenergy production from abandoned croplands  

International Nuclear Information System (INIS)

Bioenergy has the unique potential to provide a dispatchable and carbon-negative component to renewable energy portfolios. However, the sustainability, spatial distribution, and capacity for bioenergy are critically dependent on highly uncertain land-use impacts of biomass agriculture. Biomass cultivation on abandoned agriculture lands is thought to reduce land-use impacts relative to biomass production on currently used croplands. While coarse global estimates of abandoned agriculture lands have been used for large-scale bioenergy assessments, more practical technological and policy applications will require regional, high-resolution information on land availability. Here, we present US county-level estimates of the magnitude and distribution of abandoned cropland and potential bioenergy production on this land using remote sensing data, agriculture inventories, and land-use modeling. These abandoned land estimates are 61% larger than previous estimates for the US, mainly due to the coarse resolution of data applied in previous studies. We apply the land availability results to consider the capacity of biomass electricity to meet the seasonal energy storage requirement in a national energy system that is dominated by wind and solar electricity production. Bioenergy from abandoned croplands can supply most of the seasonal storage needs for a range of energy production scenarios, regions, and biomass yield estimates. These data provide the basis for further down-scalin provide the basis for further down-scaling using models of spatially gridded land-use areas as well as a range of applications for the exploration of bioenergy sustainability.

On the Construction of a New Stellar Classification Template Library for the LAMOST Spectral Analysis Pipeline  

Science.gov (United States)

The LAMOST spectral analysis pipeline, called the 1D pipeline, aims to classify and measure the spectra observed in the LAMOST survey. Through this pipeline, the observed stellar spectra are classified into different subclasses by matching with template spectra. Consequently, the performance of the stellar classification greatly depends on the quality of the template spectra. In this paper, we construct a new LAMOST stellar spectral classification template library, which is supposed to improve the precision and credibility of the present LAMOST stellar classification. About one million spectra are selected from LAMOST Data Release One to construct the new stellar templates, and they are gathered in 233 groups by two criteria: (1) pseudo g - r colors obtained by convolving the LAMOST spectra with the Sloan Digital Sky Survey ugriz filter response curve, and (2) the stellar subclass given by the LAMOST pipeline. In each group, the template spectra are constructed using three steps. (1) Outliers are excluded using the Local Outlier Probabilities algorithm, and then the principal component analysis method is applied to the remaining spectra of each group. About 5% of the one million spectra are ruled out as outliers. (2) All remaining spectra are reconstructed using the first principal components of each group. (3) The weighted average spectrum is used as the template spectrum in each group. Using the previous 3 steps, we initially obtain 216 stellar template spectra. We visually inspect all template spectra, and 29 spectra are abandoned due to low spectral quality. Furthermore, the MK classification for the remaining 187 template spectra is manually determined by comparing with 3 template libraries. Meanwhile, 10 template spectra whose subclass is difficult to determine are abandoned. Finally, we obtain a new template library containing 183 LAMOST template spectra with 61 different MK classes by combining it with the current library.

Pipeline of a nuclear reactor  

International Nuclear Information System (INIS)

The invention refers to a pipeline in a nuclear reactor in which there is a medium under pressure. According to the invention, the pipeline is entirely surrounded by a protective pipe sealed at both ends and under normal operating conditions without any pressure in order to prevent an outflow of the medium in case of a pipe burst. In an emergency, the protective pipe takes over the function of the internal pipe. A coolant tube and a main-steam pipe of a nuclear reactor are given as an example. (UWI)

Assessment of environmental implications of abandoned oil and gas wells  

International Nuclear Information System (INIS)

A detailed study was made of the potential for abandoned oil and gas wells in the Lower Tuscaloosa sand of Mississippi and Louisiana to act as conduits for movement of saline water from the Lower Tuscaloosa into underground sources of drinking water (USDW's). Finite-difference numerical modeling determined the extent that water might be forced from the Lower Tuscaloosa sand into a USDW as a result of injection into the Lower Tuscaloosa. Within the range of conditions modeled, water from the Lower Tuscaloosa never traveled into a USDW. On the basis of the modeling, the authors concluded that it is unlikely that abandoned oil and gas wells in the Lower Tuscaloosa would serve as conduits for water movement from the trend into a USDW. The procedures developed in this study should be readily applicable to analysis of the potential for abandoned wells to act as pathways for contaminant flow into USDW's in other oil and gas producing areas of the country

Determination of parameters for gamma ray examination in operation pipelines  

International Nuclear Information System (INIS)

Among the non-destructive examination (NDT) methods available for determining the existence of corrosion, and resulting thickness reduction in operation pipelines, the ultrasonic method seems to be the least expensive and the most widely used. However, this method shows inadequacies when confronted with inclusions and segregations on the pipe material that affect measurements. This recurring problem has led to gamma ray testing to evaluate is capacity of distinguishing between corrosion and inclusions. Good results have been achieved and this work includes various correction factors for several products, to be used in gamma ray examination as performed in operation pipelines, where radiation is significantly altered by the presence of the product.

Investigation of abandoned surface settling ponds  

International Nuclear Information System (INIS)

One of the problems that may appear during the ground reclamation of surface settling ponds of underground mines is enhanced radon exhalation from bottom sediments. This problem becomes more important when the concentration of radium isotopes in sediments is enhanced due to the discharge of radium-bearing waters into the pond. For investigations, special radon accumulation chambers have been designed and constructed. The concentration of radon in these chambers can be measured with the application of Lucas cells or activated charcoal detectors. In the latter method, radon is extracted from charcoal into a liquid scintillator and the sample is measured in a liquid scintillation spectrometer. Therefore the lower limit of detection (LLD) of the second method is as low as 0.1 mBq·m-2s-1, while the LLD for Lucas cells is 1.5 mBq·m-2s-1. The above-mentioned methods for the measurement of radon exhalation have been applied to investigations of a surface settling pond of one Polish coal mine, abandoned and emptied at the beginning of 2002. An agreement between the mine management and the local authority was to make the ground reclamation of the pond. A thick layer of sediments with an enhanced concentration of radium isotopes covers the bottom of the pond. The maximum concentration of radium isotopes in these sediments is as high as 2000 Bq/kg for 226Ra and up to 4000 Bq/kg for 228Ra. Two years after the compup>228Ra. Two years after the complete release of brines from the pond, bottom sediments are still soaked with water. Therefore, measurements of radon in soil gas were not possible. On the other hand, in some parts of the pond investigations of radon exhalation coefficient were done. The preliminary results of measurements, conducted in 2002, showed that radon exhalation rates in specific parts of the pond were higher than the highest values of radon exhalation from the ground in the Upper Silesia region. Values of exhalation coefficient up to 200 mBq·m-2s-1 were found. It must be pointed out that preliminary measurements were done in a period when the water had been only partly removed from the pond, and further dry-up of sediments should lead to an increase in radon exhalation. Data from 2003 confirm this assumption. During this period the water content in the bottom sediments was significantly lower than previously, and results of measurements of radon exhalation were sometimes above 300 mBq·m-2s-1. Vegetation transgression into the pond occurred during 2003, mainly weeds. Samples of vegetation were collected from this area to measure the content of radium isotopes and to calculate the transfer factors for radium isotopes. Very high concentrations of radium isotopes were found at several sites. Another reason for the pollution might be the leaching of radium from sediments and contamination of groundwater. Therefore the above mentioned sources of radiation hazard must be taken into account for planning and designing of reclamation operations for surface settling ponds of underground mines. (author)

New technology trends for effective plug and abandonment  

OpenAIRE

Plug and Abandonment (P&A) has become a major focus in the petroleum industry and especially in Norway due to the maturity of the fields. Therefore, an extensive number of wells to be abandoned just show how big the challenge will be and how much focus the regulatory authorities should include into this issue. From an operational point of view, P&A is the last phase of the life cycle of a well and hence no return of capital from it is actually expected. Furthermore, the driver for o...

Special signalizing of the Grande River crossing with the OSBRA pipeline  

Energy Technology Data Exchange (ETDEWEB)

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.

Focus on safety : a comparative analysis of pipeline safety performance 2000-2002  

International Nuclear Information System (INIS)

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 increaslities 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

Maintenance planning under imperfect inspections of corroded pipelines  

International Nuclear Information System (INIS)

In this paper, a maintenance policy is proposed for pipelines subject to corrosion, by taking into account imperfect inspection results. The degradation of the pipeline is induced by uniform and pitting corrosion, leading to losses in the pipe wall thickness. The inspection is applied to detect the corrosion defects, namely the corrosion depth and width. The inspection has a detection threshold under which no corrosion can be measured. Due to uncertainties, each inspection is affected by the probability of detecting small defects and the probability of wrong assessment in terms of defect existence and size. The present work aims at integrating imperfect inspection results in the cost model for corroded pipelines, where the failure probabilities are computed by reliability methods. A numerical application on a gas pipe shows the influence of inspection quality and cost on the choice of the optimal maintenance planning

Design considerations for paste and thickened tailings pipeline systems  

Energy Technology Data Exchange (ETDEWEB)

Paste and thickened tailings systems are high-density slurries. The drivers for developing paste and thickened tailings include shortage of water in arid regions; potential for reduced environmental impact; increased stability; and new technology. In the oil sands industry, these tailings offer high consolidation, reduced storage volume and heat recovery. This presentation described the rheomalaxis behaviour of paste and thickened tailings in terms of their unsheared to fully sheared properties. It also outlined Paterson and Cooke's newly developed proprietary flow behaviour models to predict the flow behaviour of slurries in pipelines. The design of single and multiphase pipeline systems was also presented. It was concluded that although the technology for paste and thickened tailings pipelines is well developed, more work is needed to better understand laminar flow behaviour of wide particle size distribution tailings. tabs., figs.

Full Text Available The pipeline for macro- and microarray analyses (PMmA) is a set of scripts with a web interface developed to analyze DNA array data generated by array image quantification software. PMmA is designed for use with single- or double-color array data and to work as a pipeline in five classes (data forma [...] t, normalization, data analysis, clustering, and array maps). It can also be used as a plugin in the BioArray Software Environment, an open-source database for array analysis, or used in a local version of the web service. All scripts in PMmA were developed in the PERL programming language and statistical analysis functions were implemented in the R statistical language. Consequently, our package is a platform-independent software. Our algorithms can correctly select almost 90% of the differentially expressed genes, showing a superior performance compared to other methods of analysis. The pipeline software has been applied to 1536 expressed sequence tags macroarray public data of sugarcane exposed to cold for 3 to 48 h. PMmA identified thirty cold-responsive genes previously unidentified in this public dataset. Fourteen genes were up-regulated, two had a variable expression and the other fourteen were down-regulated in the treatments. These new findings certainly were a consequence of using a superior statistical analysis approach, since the original study did not take into account the dependence of data variability on the average signal intensity of each gene.

Pipeline bottoming cycle study. Final report  

Energy Technology Data Exchange (ETDEWEB)

The technical and economic feasibility of applying bottoming cycles to the prime movers that drive the compressors of natural gas pipelines was studied. These bottoming cycles convert some of the waste heat from the exhaust gas of the prime movers into shaft power and conserve gas. Three typical compressor station sites were selected, each on a different pipeline. Although the prime movers were different, they were similar enough in exhaust gas flow rate and temperature that a single bottoming cycle system could be designed, with some modifications, for all three sites. Preliminary design included selection of the bottoming cycle working fluid, optimization of the cycle, and design of the components, such as turbine, vapor generator and condensers. Installation drawings were made and hardware and installation costs were estimated. The results of the economic assessment of retrofitting bottoming cycle systems on the three selected sites indicated that profitability was strongly dependent upon the site-specific installation costs, how the energy was used and the yearly utilization of the apparatus. The study indicated that the bottoming cycles are a competitive investment alternative for certain applications for the pipeline industry. Bottoming cycles are technically feasible. It was concluded that proper design and operating practices would reduce the environmental and safety hazards to acceptable levels. The amount of gas that could be saved through the year 2000 by the adoption of bottoming cycles for two different supply projections was estimated as from 0.296 trillion ft/sup 3/ for a low supply projection to 0.734 trillion ft/sup 3/ for a high supply projection. The potential market for bottoming cycle equipment for the two supply projections varied from 170 to 500 units of varying size. Finally, a demonstration program plan was developed.

Potential effects of large linear pipeline construction on soil and vegetation in ecologically fragile regions.  

Science.gov (United States)

Long-distance pipeline construction results in marked human disturbance of the regional ecosystem and brings into question the safety of pipeline construction with respect to the environment. Thus, the direct environmental impact and proper handling of such large projects have received much attention. The potential environmental effects, however, have not been fully addressed, particularly for large linear pipeline projects, and the threshold of such effects is unclear. In this study, two typical eco-fragile areas in western China, where large linear construction projects have been conducted, were chosen as the case study areas. Soil quality indices (SQI) and vegetation indices (VI), representing the most important potential effects, were used to analyze the scope of the effect of large pipeline construction on the surrounding environment. These two indices in different buffer zones along the pipeline were compared against the background values. The analysis resulted in three main findings. First, pipeline construction continues to influence the nearby eco-environment even after a 4-year recovery period. During this period, the effect on vegetation due to pipeline construction reaches 300 m beyond the working area, and is much larger in distance than the effect on soil, which is mainly confined to within 30 m either side of the pipeline, indicating that vegetation is more sensitive than soil to this type of human disturbance. However, the effect may not reach beyond 500 m from the pipeline. Second, the scope of the effect in terms of distance on vegetation may also be determined by the frequency of disturbance and the intensity of the pipeline construction. The greater the number of pipelines in an area, the higher the construction intensity and the more frequent the disturbance. Frequent disturbance may expand the effect on vegetation on both sides of the pipeline, but not on soil quality. Third, the construction may eliminate the stable, resident plant community. During the recovery period, the plant community in the work area of the pipeline is replaced by some species that are rare or uncommon in the resident plant community because of human disturbance, thereby increasing the plant diversity in the work area. In terms of plant succession, the duration of the recovery period has a direct effect on the composition and structure of the plant community. The findings provide a theoretical basis and scientific foundation for improving the environmental impact assessment (EIA) of oil and gas pipeline construction as it pertains to the desert steppe ecosystem, and provide a reference point for recovery and management of the eco-environment during the pipeline construction period.

The Alaska Highway Pipeline project  

International Nuclear Information System (INIS)

As natural gas is becoming the fuel of choice for new electric generation capacity, the demand is increasing rapidly and supply from traditional producing basins is not keeping up. There is a need to connect new sources of gas to the North American grid. Foothills Pipelines Ltd. believe that the gas reserves at Prudhoe Bay and in the Mackenzie Delta will be sent to market at different times via different pipelines. It is also believed that the Alaska Highway Project will be constructed for many valid reasons. Gas development is much more advanced in Alaska than in northern Canada and in addition, the project has already been approved and half of the right-of-way has been acquired. The Alaska Highway pipeline has the support of Alaska and it will follow an existing transportation corridor and will therefore have fewer environmental issues. The Alaskan North Slope has proven reserves of 30-35 Tcf and a production of about 8 Bcfd. During the course of this project, Foothills Pipelines Ltd. will address timing issues, commercial issues, needs of the First nations people as well as the needs of Alaska, Yukon and the Northwest Territories. 11 figs

Shipbuilding pipeline production quality improvement  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: The pipeline production is one of major processes in shipbuilding industry. Quality improvement and risk assessment in this process can yield significant savings, both in terms of internal quality costs as well as in terms of customer satisfactions.Design/methodology/approach: Shipbuilding pipeline production quality improvement has been carried out by application of FMEA (Failure Mode and Effect Analysis method. For the successful implementation of FMEA method it is necessary to identify process failure modes or possibility of the appearance of non-compliance, as well as their possible causes. For qualitative analysis of key input variables of the process, in the paper is used Ishikawa diagram and p-chart.Findings: It is shown that proposed approach to risk assessment in shipbuilding pipeline production is applicable to real casa scenario. The analysis has identified the points in the process with the highest probability of occurrence of nonconformities, or the highest risk for error.Research limitations/implications: As the experimenting has been conducted in shipyard, within production process, research schedule must have been set in accordance with production pace. Also, due to character of production process the data collecting was adopted to the production plan in that particular moment.Practical implications: Dealing with causes of potential nonconformities in the process can significantly contribute to the reliability and robustness of the process. Corrective actions that have been taken based on results of analysis significantly contributed to the level of quality in the pipeline production process.Originality/value: The pepper is dealing with a well known method applied in different production environment that are mostly conservative in production approach. It was shown that successful application of proposed approach can yield benefits especially in improved quality of produced pipelines within shipbuilding industry.

Corrosion mapping in pipelines  

International Nuclear Information System (INIS)

In a joint research project, BASF AG and BAM analyzed the state of the art of tangential radiography of pipes and developed more efficient methods of evaluation. Various PC applications were developed and tested: 1. A program for routine evaluation of digital radiographic images. 2. 3D simulation of the tangential projection of pipes for common radiation sources and various different detectors. 3. Preliminary work on combined evaluation of digital projections and wall thickness changes in radiation direction resulted in a new manner of image display, i.e. the so-called 'corrosion mapping', in which the wall thickness is displayed as a 2D picture above the pipe surface

Geophysical void detection at the site of an abandoned limestone quarry and underground mine in southwestern Pennsylvania  

International Nuclear Information System (INIS)

Locating underground voids, tunnels, and buried collapse structures continues to present a difficult problem for engineering geoscientists charged with this responsibility for a multitude of different studies. Solutions used and tested for void detection have run the gamut of surface geophysical and remote sensing techniques, to invasive trenching and drilling on closely-spaced centers. No where is the problem of locating underground voids more ubiquitous than in abandoned mined lands, and the U.S. Bureau of Mines continues to investigate this problem for areas overlying abandoned coal, metal, and nonmetal mines. Because of the great diversity of resources mined, the problem of void detection is compounded by the myriad of geologic conditions which exist for abandoned mined lands. At a control study site in southwestern Pennsylvania at the Bureau's Lake Lynn Laboratory, surface geophysical techniques, including seismic and other methods, were tested as a means to detect underground mine voids in the rather simple geologic environment of flat-lying sedimentary strata. The study site is underlain by an abandoned underground limestone mine developed in the Wymps Gap Limestone member of the Mississippian Mauch Chunk Formation. Portals or entrances into the mine, lead to drifts or tunnels driven into the limestone; these entries provided access to the limestone where it was extracted by the room-and-pillar method. The workings lie less than 300 ft from the surface, and surless than 300 ft from the surface, and survey lines or grids were positioned over the tunnels, the room-and-pillar zones, and the areas not mined. Results from these geophysical investigations are compared and contrasted. The application of this control study to abandoned mine void detection is apparent, but due to the carbonate terrain of the study site, the results may also have significance to sinkhole detection in karst topography

IDC Infrasound Pipeline initiative for technology development  

Science.gov (United States)

The first atmospheric event built only from infrasound arrivals was reported in the Reviewed Event Bulletin (REB) of the International Data Centre (IDC) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) in 2003. In the last decade, 45 infrasound stations from the International Monitoring System (IMS) have been installed and are transmitting data to the IDC. The growing amount of infrasound data and detections produced by the automatic system challenged the station and network processing at the IDC, which require the Organization to continually improve the infrasound data processing. For 3 years, the IDC resumed automatic processing of infrasound data reviewed by interactive analysis; the detected and located events are being systematically included in the Late Event Bulletin (LEB) and REB. Approximately 16% of SEL3 (Selected Event List 3, produced 6 hours after real-time) events with an infrasound component make it to the IDC bulletins. 41% of SEL3 events rejected after review are built including only 2 associated infrasound phases (with the potential addition of seismic and hydroacoustic detections). Therefore, the process whereby infrasound and seismic detections are associated into an event needed to be investigated further. The IDC works on enhancing the automatic system for the identification of valid signals and the optimization of the network detection threshold. Thus the IDC investigates ways to refine the signal characterization methodology and the association criteria. The objective of this study is to reduce the number of associated infrasound arrivals that are rejected from the SEL3 pipeline when generating the LEB and REB bulletins. The study is twofold, the first part consist of improving the detection accuracy at the station processing stage in the IDC development area by enhancing the infrasound signal detector DFX-PMCC (Detection and Feature eXtraction - Progressive Multi-Channel Correlation) used at the IDC. The second part is performed in the virtual Data Exploitation Center (vDEC) from the CTBTO in order to separate the automatic network processing into two streams: seismic and hydroacoustic (SH) pipeline on one side, and infrasound (I) pipeline on the other side. The IDC executes its association algorithm called Global Association (GA) on infrasound data for selective periods of times, which follow the introduction of infrasound in the IDC automatic system. Infrasound rules in GA are tuned to pursue a lower ratio of false alarms and the IRED (IDC Infrasound Reference Event Database) is used for testing and validation of potential modification in the infrasound processing software and algorithms. Once modifications are validated in the Infrasound Only Pipeline, the updated algorithms will be implemented in the development area of the IDC for further assessment of their performances in fusion with other waveform technologies.

Building the Alaska pipeline : story of a legend : Frank Moolin  

Energy Technology Data Exchange (ETDEWEB)

This article chronicled the events that took place during the building of the Alaska Pipeline from Prudhoe Bay on Alaska's Northern Coast to the Port of Valdez. In particular, it highlighted the project management led by senior project manager Frank Moolin. The oil companies officially announced their plans to begin the pipeline in February 1969. The estimated cost was $900 million, and completion was targeted for 1972. Moolin was hired by Alyeska, the company formed to design and build the pipeline. The Alaska Pipeline project was launched with little more than a goal and no clear roadmap for achieving it. Project critics claimed that it was impossible to build an 800-mile pipeline through the Alaskan wilderness using conventional methods. In addition to facing obstacles, contingency scenarios, and timetable problems, the oil companies were stopped by environmental groups and Native Alaskans who had no intention of allowing the pipeline to be built on their land. In response, oil companies wanted to lay the pipeline underground, but geologists pointed out that a large portion of Alaska rests on permafrost that cannot support any weight when it thaws. Geological testing revealed that nearly 400 miles of the pipeline had to be built above ground. In January 1974, Frank Moolin's construction crew of 20,000 people began the preparatory work. First, a supply road was built through the northern half of Alaska, from the Yukon River north of Fairbanks to Prudhoe Bay. By March 1975, three million tons of pipe, machinery, spare parts, fuel and food were hauled in, and the pipe-laying began. Moolin motivated his workers and kept morale high throughout the difficult building process. For two years, Moolin kept the problem-ridden project on track. Twelve pump stations had to be built so that 800 miles of pipe could be welded together 40 feet at a time. On June 20, 1977, the valves at Prudhoe Bay were opened, and the first Alaskan crude oil began to flow. The final tab on the Alaska Pipeline project was $8 billion, 10 times the original estimate. 1 fig.

Economic model of pipeline transportation systems  

Energy Technology Data Exchange (ETDEWEB)

The objective of the work reported here was to develop a model which could be used to assess the economic effects of energy-conservative technological innovations upon the pipeline industry. The model is a dynamic simulator which accepts inputs of two classes: the physical description (design parameters, fluid properties, and financial structures) of the system to be studied, and the postulated market (throughput and price) projection. The model consists of time-independent submodels: the fluidics model which simulates the physical behavior of the system, and the financial model which operates upon the output of the fluidics model to calculate the economics outputs. Any of a number of existing fluidics models can be used in addition to that developed as a part of this study. The financial model, known as the Systems, Science and Software (S/sup 3/) Financial Projection Model, contains user options whereby pipeline-peculiar characteristics can be removed and/or modified, so that the model can be applied to virtually any kind of business enterprise. The several dozen outputs are of two classes: the energetics and the economics. The energetics outputs of primary interest are the energy intensity, also called unit energy consumption, and the total energy consumed. The primary economics outputs are the long-run average cost, profit, cash flow, and return on investment.

Quantitative risk analysis preoperational of gas pipeline  

Energy Technology Data Exchange (ETDEWEB)

The purpose of this analysis is to predict how it can be affected the individual risk and the public's general security due to the operation of a gas pipeline. In case that the single or social risks are considered intolerable, compared with the international standards, to be recommended measures of mitigation of the risk associated to the operation until levels that can be considered compatible with the best practices in the industry. The quantitative risk analysis calculates the probability of occurrence of an event based on the frequency of occurrence of the same one and it requires a complex mathematical treatment. The present work has as objective to develop a calculation methodology based on the previously mentioned publication. This calculation methodology is centered in defining the frequencies of occurrence of events, according to representative database of each case in study. Besides, it settles down the consequences particularly according to the considerations of each area and the different possibilities of interferences with the gas pipeline in study. For each one of the interferences a typical curve of ignition probabilities is developed in function from the distance to the pipe. (author)

Improvement in treatment of mixtures generated between batches of different products in OSBRA (Sao Paulo Brasilia Pipeline) pipeline  

Energy Technology Data Exchange (ETDEWEB)

The Sao Paulo Brasilia Pipeline (OSBRA) starts at the Planalto Refinery (REPLAN) and supplies gasoline, diesel oil and LPG to the mid-west region of Brazil. The pipeline is 786 kilometers long with diameter of 20 inches in its first segment and 178 kilometers with 12 inches in the second. The fuels are pumped by seven unmanned pump stations and are delivered to five tank farms. At first, these products were pumped into the pipeline in batches of diesel or LPG between gasoline batches. These sequences allowed the dilution of the mixtures generated between the two products during the pipeline transportation to the pure product tanks, keeping compliance to the former standards. The diesel/gasoline mixtures were diluted direct to pure product tanks and the LPG/gasoline mixtures were submitted to flashing in a vessel before dilution. In 2001, the National Petroleum Agency changed the LPG and diesel oil standards. This new regulation turned the OSBRA installations unable to dilute the whole mixture volume generated during pipeline transportation. Sending part of the mixture back to the Refinery turned a mandatory task, increasing the costs and making the LPG pipeline transportation unprofitable. To overcome this situation, a new product was developed - QINTER. The QINTER can be diluted in suitable rates either to diesel or gasoline keeping the compliance of these fuels to the new standards at the receiving tanks. The QINTER is currently pumped into the pipeline between the batches of diesel oil and gasoline. The standard solution to treat the mixture created between LPG and gasoline batches, a fractional tower, was studied but it showed to be of dubious profitability and it would compel changes to the existing working schedule time, from Monday to Friday (6:00 am to 10:00 pm) to a 24:00 h/day continuous work. An alternative project was developed. Three flash recirculation vessels were designed to allow the mixtures of LPG with vapor stream and gasoline with liquid stream to keep to the new standards. This solution is seven times cheaper and it allow keeping up to the original working schedule time. Furthermore, a new operational procedure was established launching pigs at the edges of the mixtures. The aim of this pig procedure was to reduce LPG/Gasoline mixture volumes that should be treated before dilutions at the receiving tank/vessel. Pipeline shutdowns were minimized and mixture entrances into the manifold pump stations were controlled to reduce the mixture volumes. This paper describes the new technologies developed and the auspicious final results obtained. (author)

Mineral phases identification inside an abandoned Zn/Pb mine  

International Nuclear Information System (INIS)

Complete text of publication follows. The aim of the work is the identification of the sulphurated phase's outbreak on an aragonite, dolomite and calcite-based original rock inside an abandoned mine. The studied Blende/Galena (ZnS/PbS) Mine, located in Lanestosa (Bizkaia, North of Spain) was operative until 1950. After decades, the area has only supported wild life and thus nowadays it could be considered as a polluted site which has become naturalized. The main alteration factors inside the mine are percolated water, gases come from the outside (CO2, O2) and biological activities. Mining activities generates loads of ore minerals and unwanted materials that with the time impact the surrounding environment. The waste includes granular, broken rock and soils ranging in size from the fine sand to large boulders, with the content of fine material largely dependent on the nature of the formation and extraction methods employed during mining. Waste materials geochemistry varies widely from mine to mine and may vary significantly at individual mines over time as different lithologic strata are exposed and geochemical processes alter characteristics of the waste. In order to determine the finest mineral composition in the galleries, several samples were collected. Once dried in a fume hood and sieved, the portions below 250 ?m were subjected to non-destructive Raman spectroscopic analysis. The measurements reflected the ore precursors (primary phases: cted the ore precursors (primary phases: Blende, and Galena), several primary carbonates (dolomite, calcite and aragonite) with secondary minerals in trace levels (Brookite, Libethenite, Fluorapatita, Anatasa, Quartz, Apatite, Augite, Diopside, Anthracite, Hematite, Cosalite, Epidote, Rutile) and transformation products, probably of recent formation (Smithsonite, Massicot, Plattnerite, Gypsum, Siderite, Mendiphite, Escorodite, Gauberite, Goethite or Mascagnite). The origin of the secondary mineral may be related to percolated rain and snow water. This hypothesis is based in the acidic snow water collected in January of 2009 (pH?5). Acid water dissolves all carbonates and all those soluble salts leached in surface (ZnCO3 or PbCO3). Finally, a basic thermodynamic model has been developed in order to explain the primary mineral phases transformation to the secondary ones. Acknowledgements.

Oil pipeline valve automation for spill reduction  

Energy Technology Data Exchange (ETDEWEB)

Liquid pipeline codes generally stipulate placement of block valves along liquid transmission pipelines such as on each side of major river crossings where environmental hazards could cause or are foreseen to potentially cause serious consequences. Codes, however, do not stipulate any requirement for block valve spacing for low vapour pressure petroleum transportation, nor for remote pipeline valve operations to reduce spills. A review of pipeline codes for valve requirement and spill limitation in high consequence areas is thus presented along with a criteria for an acceptable spill volume that could be caused by pipeline leak/full rupture. A technique for deciding economically and technically effective pipeline block valve automation for remote operation to reduce oil spilled and control of hazards is also provided. In this review, industry practice is highlighted and application of the criteria for maximum permissible oil spill and the technique for deciding valve automation thus developed, as applied to ORSUB pipeline is presented. ORSUB is one of the three initially selected pipelines that have been studied. These pipelines represent about 14% of the total length of petroleum transmission lines operated by PETROBRAS Transporte S.A. (TRANSPETRO) in Brazil. Based on the implementation of valve motorization on these three pipeline, motorization of block valves for remote operation on the remaining pipelines is intended, depending on the success of these implementations, on historical records of failure and appropriate ranking.
