    Floating electrical power plants or power plant barges add new dimensions to utility planners and agencies in the world. Intrinsically safe and economical reactors (ISER) employ steel reactor pressure vessels, which significantly reduce the weight as compared with PIUS, and provide siting versatility including barge-mounted plants. In this paper, the outline of power plant barges and barge-mounted ISERs is described. Besides their mobility, power plant barges have the salient advantages such as short delivery time and better quality control due to the outfitting in shipyards. These power plant barges may be temporarily moored or permanently grounded in shallow water at the centers of industrial complexes or the suitable areas adjacent to them, and satisfy the increasing needs for electric power. A cost-effective and technically perfect barge positioning system should be designed to meet the specific requirement for the location and its condition. Offshore siting away from coast may be applicable only to large plants of 1,000 MWe or more, and inshore siting and coastal or river siting are considered for an ISER-200 barge-mounted plant. The system of a barge-mounted ISER plant is discussed in the case of a floating type and the type on a seismic base isolator. (Kako, I.)

    The Department of the Army is authorized to build and operate nuclear reactors for defense purposes under Paragraph 91b of the Atomic Energy Act of 1954 (1). As part of the Army Reactor Program, the United States Army Corps of Engineers (Corps) is responsible for nuclear reactor engineering and design, reactor construction, and decommissioning design and implementation (2). The Corps is currently focused on ensuring the safety and security of the Army's three deactivated power reactors and planning for their final decommissioning. To support decommissioning cost projections, the Corps is gathering information on the residual radiological and chemical hazards associated with each reactor, starting with the MH-1A reactor on the Sturgis Barge (3). Because the Sturgis Barge is moored in the James River Reserve Fleet, there were unique challenges that had to be overcome during the characterization survey and others that will become a concern when final decommissioning is to be per formed

  9. Balanced and sparse Tamo-Barg codes

    2017-08-29

    We construct balanced and sparse generator matrices for Tamo and Barg\\'s Locally Recoverable Codes (LRCs). More specifically, for a cyclic Tamo-Barg code of length n, dimension k and locality r, we show how to deterministically construct a generator matrix where the number of nonzeros in any two columns differs by at most one, and where the weight of every row is d + r - 1, where d is the minimum distance of the code. Since LRCs are designed mainly for distributed storage systems, the results presented in this work provide a computationally balanced and efficient encoding scheme for these codes. The balanced property ensures that the computational effort exerted by any storage node is essentially the same, whilst the sparse property ensures that this effort is minimal. The work presented in this paper extends a similar result previously established for Reed-Solomon (RS) codes, where it is now known that any cyclic RS code possesses a generator matrix that is balanced as described, but is sparsest, meaning that each row has d nonzeros.

    1987-01-01

    Though floating nuclear plants (FNPs) is effectively isolated from horizontal earthquake motion, vertical earthquake motion on FNPs is almost the same as the ground motion inevitably. Therefore an alternative design concept of FNPs has been developed, which is isolated from vertical earthquake motion as well, utilizing pneumatic chambers equipped to the bottom of the barge. In this report, a simple analytical solution, which describes the vertical earthquake response of a floating body which has pneumatic chambers below its bottom, is derived. And a shaking table test and an earthquake response observation of floating bodies with pneumatic chambers are conducted to verify the solution. The prediction by the analytical solution gives sufficient agreement with the experimental results, so that the solution is confirmed to be valid. Then the fundamental geometry of a FNP barge with pneumatic chambers is assumed, and finally, it is evaluated by the solution that high-frequency ( ≥ 1 Hz) vertical acceleration on the barge induced by vertical component of earthquakes, will be reduced to approximately, a quater of the ground motion.

    Large Electric Dispersal Barriers were constructed in the Chicago Sanitary and Ship Canal (CSSC) to prevent the transfer of invasive fish species between the Mississippi River Basin and the Great Lakes Basin while simultaneously allowing the passage of commercial barge traffic. We investigated the potential for entrainment, retention, and transport of freely swimming fish within large gaps (> 50 m3) created at junction points between barges. Modified mark and capture trials were employed to assess fish entrainment, retention, and transport by barge tows. A multi-beam sonar system enabled estimation of fish abundance within barge junction gaps. Barges were also instrumented with acoustic Doppler velocity meters to map the velocity distribution in the water surrounding the barge and in the gap formed at the junction of two barges. Results indicate that the water inside the gap can move upstream with a barge tow at speeds near the barge tow travel speed. Water within 1 m to the side of the barge junction gaps was observed to move upstream with the barge tow. Observed transverse and vertical water velocities suggest pathways by which fish may potentially be entrained into barge junction gaps. Results of mark and capture trials provide direct evidence that small fish can become entrained by barges, retained within junction gaps, and transported over distances of at least 15.5 km. Fish entrained within the barge junction gap were retained in that space as the barge tow transited through locks and the Electric Dispersal Barriers, which would be expected to impede fish movement upstream.

    2015-01-01

    Full Text Available The article discusses a unique Belyana barge, which was built in the Nizhny Novgorod region for several centuries. Belyana as a type of vessels was designed for transportation of logs, sleepers, beams, planks and other forest products from the Upper to the Lower Volga. Originally, the center of Belyana construction was the village of Baki, which was situated on the Vetluga River, a tributary of the Volga River. The Belyana construction technique spread from the Vetluga river banks further to Nizhny Novgorod, and then to Perm region. Almost all aspects of Belyana construction starting from the logging finishing with its floating to the lower Volga, and also cost of transported products in the prices of the XIX century are disclosed. Due to Belyana is truly a popular invention, it was built by traditional methods, relying solely on the centuries-old experience. Any drawings for the construction never existed, that’s why the author relied on preserved photographs and drawings in the historical reconstruction of this unique vessel. At the beginning of the article a brief overview of the geographical location of Nizhny Novgorod, as well as the names of wooden ships which were sailing on Volga and its tributaries in the same times with Belyana are given. At the end of the article practical recommendations on possible reconstruction of Belyana and using it as an interactive museum of ethnography are given.

  3. A mixed integer linear programming model applied in barge planning for Omya

    Directory of Open Access Journals (Sweden)

    David Bredström

    2015-12-01

    Full Text Available This article presents a mathematical model for barge transport planning on the river Rhine, which is part of a decision support system (DSS recently taken into use by the Swiss company Omya. The system is operated by Omya’s regional office in Cologne, Germany, responsible for distribution planning at the regional distribution center (RDC in Moerdijk, the Netherlands. The distribution planning is a vital part of supply chain management of Omya’s production of Norwegian high quality calcium carbonate slurry, supplied to European paper manufacturers. The DSS operates within a vendor managed inventory (VMI setting, where the customer inventories are monitored by Omya, who decides upon the refilling days and quantities delivered by barges. The barge planning problem falls into the category of inventory routing problems (IRP and is further characterized with multiple products, heterogeneous fleet with availability restrictions (the fleet is owned by third party, vehicle compartments, dependency of barge capacity on water-level, multiple customer visits, bounded customer inventories and rolling planning horizon. There are additional modelling details which had to be considered to make it possible to employ the model in practice at a sufficient level of detail. To the best of our knowledge, we have not been able to find similar models covering all these aspects in barge planning. This article presents the developed mixed-integer programming model and discusses practical experience with its solution. Briefly, it also puts the model into the context of the entire business case of value chain optimization in Omya.

  4. An Innovative Steering System for a River Push Barge Operated in Environmentally Sensitive Areas

    Directory of Open Access Journals (Sweden)

    Abramowicz-Gerigk Teresa

    2017-12-01

    Full Text Available The paper presents an innovative steering system for a river push barge dedicated for operation in environmentally sensitive inland waterways. Development of the inland waterborne transport in Poland is dependent on the exploitation of rivers which can be adapted to navigation in the limited range because a high percent of their length is classified within special environment protection areas of Natura 2000 network. This is now the main reason that their better exploitation cannot be obtained without an introduction of a new generation of waterborne environment friendly inland units. In naturally winding rivers with differing and rapidly changing depths and widths it is important to equip a push barge with an efficient steering system that has a low environmental impact. The innovative steering system proposed in the paper is composed of main steering devices located at the pusher stern, auxiliary steering devices installed on the barge bow and a mechanical coupling system.

    Low water levels are a potential threat to the inland navigation market. We develop a theoretical model to analyze low water-level uncertainty in the inland navigation market. A negative effect of climate change on welfare is expected due to the increase in cost per tonne of transport when low water levels occur more frequently. The market actors may take measures to adapt to the new situation of climate change. As an example, we study barge-size adjustments by barge operators. We show that i...

  10. Synthesis and Race: Barge, Buytendijk, and the rassenvraagstuk of the 1930s

    Directory of Open Access Journals (Sweden)

    Sebastiaan Broere

    2017-02-01

    Full Text Available On the basis of two case studies, this article demonstrates that throughout the 1930s “synthetic reasoning” in the Netherlands provided arguments to denounce racial reductionism and eugenicist policy. These two case studies concern the anatomist and physical anthropologist J.A.J. Barge (1884-1952 and the physiologist and psychologist F.J.J. Buytendijk (1887-1974. Barge and Buytendijk participated in a public debate on race and fiercely contested the claim – from their perspective primarily defended by German scientists – that heritable, racial factors determined personality and physiology. Christian principles undoubtedly motivated Barge and Buytendijk to raise their voices, but in criticizing the public uses of race, they based their arguments, above all, on epistemological considerations. This article examines theoretical investigations by Buytendijk and Barge into the foundations of the life sciences, the “race question” of the 1930s, and the 1939 Seminar on the Race Question organized by the Catholic University in Nijmegen. Although both intellectuals supported the broadening of explanatory schemes in biology and the human sciences, they differed on the question what synthesis meant with regard to the concept of race.

    A barge-mounted hydrogen-fueled proton exchange membrane (PEM) fuel cell system has the potential to reduce emissions and fossil fuel use of maritime vessels in and around ports. This study determines the technical feasibility of this concept and examines specific options on the U.S. West Coast for deployment practicality and potential for commercialization.The conceptual design of the system is found to be straightforward and technically feasible in several configurations corresponding to various power levels and run times.The most technically viable and commercially attractive deployment options were found to be powering container ships at berth at the Port of Tacoma and/or Seattle, powering tugs at anchorage near the Port of Oakland, and powering refrigerated containers on-board Hawaiian inter-island transport barges. Other attractive demonstration options were found at the Port of Seattle, the Suisun Bay Reserve Fleet, the California Maritime Academy, and an excursion vessel on the Ohio River.

  20. Time Domain Response Analysis of Barge Floater Supporting an Offshore Wind Turbine

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Wind energy is a reliable source of sustainable power generation and has been an active area of research globally to economically harness the energy for human use. Reliable source of wind energy pushed the engineers to install wind turbines near and far off the coasts. In shallow water upto 100 m, fixed structures like tripods, jackets, monopiles and gravity base are functionally and economically feasible. In deep waters, a floating substructure can be more economical for offshore wind turbine. In this study a barge type floater of different aspect ratios from 0.4 to 1.0 is investigated for its performance under wave and wind loading. All these floaters were designed with a defined transverse metacentric height (GM equal to 1.0 m and the hydrodynamic analysis is carried out using WAMIT. The barge with aspect ratio B/L = 1.0 is found to have lowest pitch RAO. The time domain surge, heave and pitch response for this barge has been obtained using Integro-differential equation of motion and the statistical response characteristics are compared for two different cases of excitation namely, wave excitation alone and combined wave and wind excitation. Statistics of surge, heave and pitch responses are obtained for three different seas states and for two different wave heading angles.

    Although airborne respiratory irritants at the World Trade Center (WTC) site have been associated with asthma among WTC Ground Zero workers, little is known about asthma associated with work at the Staten Island landfill or barges. To evaluate the risk of asthma first diagnosed among Staten Island landfill and barge workers, we conducted a survey and multivariable logistic regression analysis regarding the association between Staten Island landfill and barge-related work exposures and the onset of post-9/11 asthma. Asthma newly diagnosed between September 11, 2001 and December 31, 2004 was reported by 100/1,836 (5.4%) enrollees. Jobs involving sifting, digging, welding, and steel cutting, enrollees with high landfill/barge exposure index scores or who were police and sanitation workers, and enrollees with probable posttraumatic stress disorder all had increased odds ratios for new-onset asthma. Post-9/11 asthma cumulative incidence among Staten Island landfill/barge workers was similar to that of other WTC disaster rescue and recovery workers. Am. J. Ind.

    2009-11-01

    Migrating juvenile wild Chinook salmon Oncorhynchus tshawytscha, collected and loaded onto transport barges at Lower Granite Dam on the Snake River, were sampled from barges at John Day Dam, 348 km downstream, at 5 day intervals beginning in late April and ending in late May. An increase in lipid peroxidation and decrease in vitamin E in liver were observed from early to late in the barge transportation season. These changes seemed unrelated to changes in plasma cortisol or corresponding glucose levels, which declined from early to late in the season, or the concentration of n-3 highly unsaturated fatty acid (HUFA) concentrations in tissue but may be related to water temperature, which increased during the transport season, or other changes associated with the parr-smolt transformation.

  6. Barge loading facilities in conjunction with wood chipping and sawlog mill, Tennessee River Mile 145. 9R: Environmental assessment

    Energy Technology Data Exchange (ETDEWEB)

    1990-08-01

    The purpose of this Environmental Assessment (EA) is to evaluate the environmental consequences of approving, denying, or adopting reasonable alternatives to a request for barge loading facilities. These facilities would serve a proposed wood chipping and sawlog products operation at Tennessee River Mile (TRM) 145.9, right descending bank, (Kentucky Lake), in Perry County, Tennessee. The site is located between Short Creek and Peters Landing. The applicant is Southeastern Forest Products, L.P. (SFP), Box 73, Linden, Tennessee and the proposed facilities would be constructed on or adjacent to company owned land. Portions of the barge terminal would be constructed on land over which flood easement rights are held by the United States of America and administered by the Tennessee Valley Authority (TVA). The US Army Corps of Engineers (CE) and TVA have regulatory control over the proposed barge terminal facilities since the action would involve construction in the Tennessee River which is a navigable water of the United States. The wood chipping and sawlog products facilities proposed on the upland property are not regulated by the CE or TVA. On the basis of the analysis which follows, it has been determined that a modified proposal (as described herein) would not significantly affect the quality of the human environment, and does not require the preparation of an environmental impact statement. 8 refs.

  7. Computationally Inexpensive Approach for Pitch Control of Offshore Wind Turbine on Barge Floating Platform

    2013-01-01

    Offshore floating wind turbine (OFWT) has gained increasing attention during the past decade because of the offshore high-quality wind power and complex load environment. The control system is a tradeoff between power tracking and fatigue load reduction in the above-rated wind speed area. In allusion to the external disturbances and uncertain system parameters of OFWT due to the proximity to load centers and strong wave coupling, this paper proposes a computationally inexpensive robust adaptive control approach with memory-based compensation for blade pitch control. The method is tested and compared with a baseline controller and a conventional individual blade pitch controller with the “NREL offshore 5 MW baseline wind turbine” being mounted on a barge platform run on FAST and Matlab/Simulink, operating in the above-rated condition. It is shown that the advanced control approach is not only robust to complex wind and wave disturbances but adaptive to varying and uncertain system parameters as well. The simulation results demonstrate that the proposed method performs better in reducing power fluctuations, fatigue loads and platform vibration as compared to the conventional individual blade pitch control.

    Full Text Available In order to study the physical details of viscous flow in ship roll motions and improve the accuracy of ship roll damping numerical simulation, the application of the Particle Image Velocimetry (PIV technique is investigated in model tests of forced ship rolling in calm water. The hydrodynamic force and flow field at the bilge region are simultaneously measured for barges at different amplitudes and frequencies in which the self-made forced rolling facility was used. In the model test, the viscous flow variation with the time around the bilge region was studied during ship rolling motion. The changes in ship roll damping coefficients with the rolling amplitude and period were also investigated. A comparison of the model test results with the Computational Fluid Dynamics(CFDresults shows that the numerical ship roll damping coefficients agree well with the model test results, while the differences in the local flow details exist between the CFD results and model test results. Further research into the model test technique and CFD application is required.

  9. Nonlinear roll damping of a barge with and without liquid cargo in spherical tanks

    Full Text Available Damping plays a significant role on the maximum amplitude of a vessel's roll motion, in particular near the resonant frequency. It is a common practice to predict roll damping using a linear radiation–diffraction code and add that to a linearized viscous damping component, which can be obtained through empirical, semi-empirical equations or free decay tests in calm water. However, it is evident that the viscous roll damping is nonlinear with roll velocity and amplitude. Nonlinear liquid cargo motions inside cargo tanks also contribute to roll damping, which when ignored impedes the accurate prediction of maximum roll motions. In this study, a series of free decay model tests is conducted on a barge-like vessel with two spherical tanks, which allows a better understanding of the nonlinear roll damping components considering the effects of the liquid cargo motion. To examine the effects of the cargo motion on the damping levels, a nonlinear model is adopted to calculate the damping coefficients. The liquid cargo motion is observed to affect both the linear and the quadratic components of the roll damping. The flow memory effect on the roll damping is also studied. The nonlinear damping coefficients of the vessel with liquid cargo motions in spherical tanks are obtained, which are expected to contribute in configurations involving spherical tanks.

    2007-01-01

    Full Text Available A barge-in free spoken dialogue interface using sound field control and microphone array is proposed. In the conventional spoken dialogue system using an acoustic echo canceller, it is indispensable to estimate a room transfer function, especially when the transfer function is changed by various interferences. However, the estimation is difficult when the user and the system speak simultaneously. To resolve the problem, we propose a sound field control technique to prevent the response sound from being observed. Combined with a microphone array, the proposed method can achieve high elimination performance with no adaptive process. The efficacy of the proposed interface is ascertained in the experiments on the basis of sound elimination and speech recognition.

    This report documents the baseline environmental conditions of the U. S. Department of Energy's (DOE's) K-1251 Barge Facility, which is located at the East Tennessee Technology Park (ETTP). DOE is proposing to lease the facility to the Community Reuse Organization of East Tennessee (CROET). This report provides supporting information for the use, by a potential lessee, of government-owned facilities at ETTP. This report is based upon the requirements of Sect. 120(h) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The lease footprint is slightly over 1 acre. The majority of the lease footprint is defined by a perimeter fence that surrounds a gravel-covered area with a small concrete pad within it. Also included is a gravel drive with locked gates at each end that extends on the east side to South First Avenue, providing access to the facility. The facility is located along the Clinch River and an inlet of the river that forms its southern boundary. To the east, west, and north, the lease footprint is surrounded by DOE property. Preparation of this report included the review of government records, title documents, historic aerial photos, visual and physical inspections of the property and adjacent properties, and interviews with current and former employees involved in the operations on the real property to identify any areas on the property where hazardous substances and petroleum products or their derivatives and acutely hazardous wastes were known to have been released or disposed. Radiological surveys were conducted and chemical samples were collected to assess the facility's condition.

    The multi-task barge is devoted to the exploitation of deep-sea fields in rather good conditions. It has been designed to bring together within a single installation, a production, storage and unloading unit and the necessary means for the drilling, the connecting and the work-over of wells. Thus submarine well-heads and well-head platforms are no longer needed. When the field configuration or the use of oriented drillings allows to group several wells together, the multi-task platform allows to use more economical surface production heads installed on steel rigid risers. This concept requires less investments thanks to less expensive drilling operations and restricted submarine installations, and to easier well operations and lower exploitation costs. Crude oil storage is ensured to up to about 2 millions of barrels. This paper presents the design aspects and the dynamical analysis of risers with the methods used. The tensioning and mooring system is examined and the advantages of the cylindrical float system is underlined and compared to the classical hydro-pneumatic systems. (J.S.) 11 refs.

    The isolated regions of the Amazon present difficulties for integration with the electrical system which is creating some economic problems due to the consequent costs of electric generation of subsidies as a function of the fossil fuel use as oils diesel and fuel. A viable option is the use of Natural Gas - NG that is Also available in the region. Its modal of transport possible in the Region North they are for gas-lines or barges. The Compressed Natural Gas transport is distinguished that - CNG for barges was still not tested operationally in Brazil. Soon, to develop a Preliminary Study of Viability Technician - Economic - SVTE for the implantation of fluvial transport of CNG between the cities of Coari and Manaus is basic, therefore it is created strategical alternative for the electric generation in this region. The electric sector, the characteristics of the NG and the transport in this region had been analyzed to support to the work. The gas line and the fluvial transport of CNG for barges in this region are not conflicting, and they in a complementary form can act. The SVTE presented a Liquid Present Value and Internal Tax of very attractive Return justifying its implantation. (author)

    The waterway transportation sector, despite its problems and bottlenecks, is continually seeking alternatives to improve its operations. With goals of increased efficiency, safety and cost reduction, the sector is modernizing and acquiring new technology. The Dynamic Position control system for a large barge convoy is one of the new technology highlights. This innovation may make development in the Brazilian waterway transportation sector feasible by permitting navigational safety and greater flexibility in transport and distribution not only for mined products but for petroleum and its derivatives. This paper presents the development process of The Dynamic Position control system for a large barge convoy in the Parana-Paraguay River, for Rio Tinto Mining Company. The hydrodynamics effects in a river are quite different than those of the traditional offshore environment. The degree of difficulty involved in solving this problem is highly dependent on a ship's characteristics, which can be analyzed in function of their hydrodynamic coefficients. Model tests in towing tanks were made to adjust the hydrodynamic coefficients and characteristics of the thrusters. The choice of the 'backstepping' control law and observer (state estimator) presented in this paper is a result of these particular conditions. The authors point out the advantage of using this technique, since all the properties of the coefficients of the hull, propeller(s) and thruster(s) have already been tested and tuned and are able to make a reliable set-up that optimizes navigation in restricted waterways.

    Since Floating Nuclear Plants (FNP) are considered to be isolated from horizontal seismic motion, reduction and standardization of the aseismic design conditions of the floating plants are anticipated. However, studies on FNP in closed and shallow basin have almost not been executed to data, and there are many problems remaining unsolved. The purpose of the present report is to obtain sufficient elementary data and materials on the seismic response of floating body in the closed and shallow basin. Some interesting points to be extracted from shaking table tests, finite element analyses and simplified analyses are summarized as follows: 1) The seismic isolation characteristics of the floating body are remarkable to short period horizontal seismic motion. 2) Resonances of the floating body's motion, which coupled with surface waves, are induced by long period horizontal seismic motion. 3) Vertical seismic motion is transmitted directly to the floating body.

    International Nuclear Information System (INIS)

    1990-02-01

    The purpose of this document is to provide information on burnup credit as applied to the preliminary design of the BR-100 shipping cask. There is a brief description of the preliminary basket design and the features used to maintain a critically safe system. Following the basket description is a discussion of various criticality analyses used to evaluate burnup credit. The results from these analyses are then reviewed in the perspective of fuel burnups expected to be shipped to either the final repository or a Monitored Retrievable Storage (MRS) facility. The hurdles to employing burnup credit in the certification of any cask are then outlines and reviewed. the last section gives conclusions reached as to burnup credit for the BR-100 cask, based on our analyses and experience. All information in this study refers to the cask configured to transport PWR fuel. Boiling Water Reactor (BWR) fuel satisfies the criticality requirements so that burnup credit is not needed. All calculations generated in the preparation of this report were based upon the preliminary design which will be optimized during the final design. 8 refs., 19 figs., 16 tabs

    Purpose: To completely eliminate a danger occurred by the rolling of a hull in the ocean in a method and apparatus for disposing radioactive waste container to submarine bottom by independently handling the radioactive waste containers when loading the container in a compartment carried on a barge and sinking the containers together with the compartment to the submarine bottom at its disposing time. Method: Radioactive waste containers are carried into a compartment loaded on a barge floating completely, and the barge is then applied with external force thereto by a ship or the like and sailed to the marine disposal area. Then, water is filled in the ballast tank of the barge to submerge the barge, the compartment is floated and separated from the containers, and water is charged into the compartment to sink the compartment.

Through installing the Tuned Mass Damper(TMD) on the hook, the vibration will be reduced to a certain range to meet the demand on sea work, which is also important for increasing the efficiency of sea work. To design the suitable TMD for the hook, the dynamical parameters should be specified beforehand. Generally, the related dynamical parameters such as inclinometer and acceleration are measured by wire sensors. But due to the restriction of the actual condition, the wire sensors are very hard to implement. Recently, the wireless sensors have been presented to overcome the shortcomings of wire ones. It is more suitable and also convenient to utilize wireless sensors to acquire the useful data of large scale heavy derrick lay barge. In this paper, the hook reducing swing movement control module is designed for large scale heavy derrick lay barge. Secondly, wireless inclinometer sensor system is integrated using the technique of MEMS, sensing and wireless communication. Finally, the hook reducing swing movement control module is validated by the developed wireless inclinometer data acquisition system. The wireless inclinometer sensor can be used not only in swing monitoring for large scale heavy derrick lay barge's Hook, but also in vibration monitoring for TV tower, large crane. In general, it has great application foreground.

    Full Text Available The dramatic range expansion of the dengue vector Aedes aegypti is associated with various anthropogenic transport activities, but little is known about the underlying mechanisms driving this geographic expansion. We longitudinally characterized infestation of different vehicle types (cars, boats, etc. to estimate the frequency and intensity of mosquito introductions into novel locations (propagule pressure.Exhaustive adult and immature Ae. aegypti collections were performed on six different vehicle types at five ports and two bus/ taxi departure points in the Amazonian city of Iquitos, Peru during 2013. Aquatic vehicles included 32 large and 33 medium-sized barges, 53 water taxis, and 41 speed boats. Terrestrial vehicles sampled included 40 buses and 30 taxis traveling on the only highway in the region. Ae. aegypti adult infestation rates and immature indices were analyzed by vehicle type, location within vehicles, and sampling date.Large barges (71.9% infested and medium barges (39.4% infested accounted for most of the infestations. Notably, buses had an overall infestation rate of 12.5%. On large barges, the greatest number of Ae. aegypti adults were found in October, whereas most immatures were found in February followed by October. The vast majority of larvae (85.9% and pupae (76.7% collected in large barges were produced in puddles formed in cargo holds.Because larges barges provide suitable mosquito habitats (due to dark, damp cargo storage spaces and ample oviposition sites, we conclude that they likely serve as significant contributors to mosquitoes' propagule pressure across long distances throughout the Peruvian Amazon. This information can help anticipate vector population mixing and future range expansions of dengue and other viruses transmitted by Ae. aegypti.

    Low water levels are a potential threat to the inland navigation market. We develop a theoretical model to analyze low water-level uncertainty in the inland navigation market. A negative effect of climate change on welfare is expected due to the increase in cost per tonne of transport when low water levels occur more frequently. The market actors may take measures to adapt to the new situation of climate change. As an example, we study barge-size adjustments by barge operators. We show that i...

    Since early 1980, Technip-Geoproduction (TPG), as designer or as installation contractor, has been using with success the float over system UNIDECK-TPG for the transportation and installation of integrated decks for offshore platforms. The concept offers the advantages of significant savings in transportation and installation cost by minimizing the installation time and offshore hook-up and eliminating the need for a heavy lift derrick barge. The paper describes the technology used for the installation, the required engineering studies, the consequences of using such a concept on platform design and the selection of an appropriate barge size to be used.

  20. Seismic response analysis of floating nuclear power plant

    International Nuclear Information System (INIS)

    Hagiwara, Yutaka; Nakamura, Hideharu; Shiojiri, Hiroo

    1988-01-01

    Since Floating Nuclear Power Plants (FNPs) are considered to be isolated from horizontal seismic motion, it is anticipated to reduce seismic load for plant components and buildings on the barge. On the other hand, barge oscillation and sloshing in the closed basin might be excited by earthquakes, because natural periods of those motions correspond to relatively-long period component (between 2 and 20 seconds) of seismic motion. Therefore, it is necessary to evaluate seismic isolation effects and barge oscillation, for the rational design of FNPs. However, there do not exist any reasonable analytical tools which can evaluate seismic response of floating structures in closed basin. The purpose of the present report is to develop a seismic analysis method for FNPs. The proposed method is based on the finite element method, and the formulation includes fluid-structure interaction, water surface wave, buoyancy effect, and non-linear characteristics of mooring system. Response analysis can be executed in both time-domain and frequency-domain. Shaking table tests were conducted to validate the proposed method of analysis. The test results showed significant isolation effect of floating structure, and apparent interaction between the barge and the basin. And 2-D and 3-D frequency domain analyses and the 2-D linear and non-linear time-domain analyses were done and those analyses could simulate the test results well. (author)

  2. Offshore fixed platform and method of erecting the same

    Energy Technology Data Exchange (ETDEWEB)

    Armstong, J.E.

    1979-07-17

    Disclosed is an improved fixed offshore platform and method of erecting the same. The platform has an open truss structure with upper and lower deck levels. The upper deck has removable floor sections to allow installation of equipment down through the truss structure. The platform is provided with pads for mounting equipment and housing in modules on the deck. No flotation is provided in the platform and means are provided for supporting the platoform on the deck of a simple barge. The platform is generally triangular in shape having three caisson legs with one leg enlarged to allow drilling therethrough. Jacks are provided for gripping the legs and a crane is mounted on the deck to move along tracks provided thereon. In erecting the platform, the platform is first barged to the location of installation on a simple barge with the legs in a vertically-extending position and the platform in its normal operating position with the crane thereon. The barge is moored in position over a well site. At high tide, the legs are dropped and locked in position. As the tide subsides, the barge is floated from under the platform leaving the platform supported by the legs and the jacks. Next, the platform is jacked up to the desired height of use. Pilings are driven through the legs by use of the deck mounted crane. The legs are then grouted in place and welded to the platform. The jacks are removed from the legs and the equipment modules are installed. Drilling can then be accomplished through the enlarged leg.

  3. Ship Lock as General Queuing System with Batch Arrivals and Batch Service

    Directory of Open Access Journals (Sweden)

    Zoran Radmilović

    2007-11-01

    Full Text Available The real lock operations with ships and barge convoys areconsidered dependent on the transport technologies applied, ormore precisely, the kinds of ships/convoys requiring thelockage. The fleet can be divided as follows: (1 groups of singleships, (2 pushed and pulled tows of barges and (3 differentcombinations of previous systems (1 and (2. The groups ofships and tows passing through the lock have extremely stochasticcharacteristics thus forming various arrivals and setvicetime patterns. It means that uniform navigation or strongscheduling between locks and lock operations are not possibleeven though highly sophisticated equipment is at disposal.Therefore, in this paper an analytical method was developedusing bulk queuing systems for the analysis and planning oflock requirements supporting it with numerical example. Thedeveloped methodology can be applied to determine the meanqueue length of ships - convoys at lock anchorage, withoutblocking behaviour between upstream and downstream navigationfor single-lane traffic.

  4. An Optimization Model For Strategy Decision Support to Select Kind of CPO’s Ship

    Suaibah Nst, Siti; Nababan, Esther; Mawengkang, Herman

    2018-01-01

    The selection of marine transport for the distribution of crude palm oil (CPO) is one of strategy that can be considered in reducing cost of transport. The cost of CPO’s transport from one area to CPO’s factory located at the port of destination may affect the level of CPO’s prices and the number of demands. In order to maintain the availability of CPO a strategy is required to minimize the cost of transporting. In this study, the strategy used to select kind of charter ships as barge or chemical tanker. This study aims to determine an optimization model for strategy decision support in selecting kind of CPO’s ship by minimizing costs of transport. The select of ship was done randomly, so that two-stage stochastic programming model was used to select the kind of ship. Model can help decision makers to select either barge or chemical tanker to distribute CPO.

  5. Invariant integration in 2. -->. 3 processes in quantum chromodynamics

    Duplii, S.A.; Rekalo, M.P.

    1982-11-01

    The energy and angular distributions of the quark-antiquark pair QQ-bar (treated as a whole) which is produced in the processes qq-bar..-->..QQ-barg and gq..-->..QQ-barq, where g is the gluon, q = u,d,s are the light quarks, and Q are the heavy quarks, are found to lowest order in a perturbation expansion in the quark-gluon interaction constant. The interference of the two classes of diagrams responsible for QQ-bar pair production by one and two gluons does not vanish (in contrast to quantum electrodynamics). The technique of invariant integration developed in quantum electrodynamics is generalized to the case of quantum chromodynamics. This allows the analytic calculation of all contributions to the differential cross section of the processes qq-bar..-->..QQ-barg and gq..-->..QQ-barq, integrated over the final QQ-bar pair.

  6. Intermodal transportation of spent fuel

    International Nuclear Information System (INIS)

    Elder, H.K.

    1983-09-01

    Concepts for transportation of spent fuel in rail casks from nuclear power plant sites with no rail service are under consideration by the US Department of Energy in the Commercial Spent Fuel Management program at the Pacific Northwest Laboratory. This report identifies and evaluates three alternative systems for intermodal transfer of spent fuel: heavy-haul truck to rail, barge to rail, and barge to heavy-haul truck. This report concludes that, with some modifications and provisions for new equipment, existing rail and marine systems can provide a transportation base for the intermodal transfer of spent fuel to federal interim storage facilities. Some needed land transportation support and loading and unloading equipment does not currently exist. There are insufficient shipping casks available at this time, but the industrial capability to meet projected needs appears adequate

  7. Optimal Control of an Offshore Lifting Operation

    Directory of Open Access Journals (Sweden)

    Kåre M. Mjelde

    1984-04-01

    Full Text Available The optimal control of an offshore operation is analysed: a hideck which is at rest on a barge is lifted from the barge by means of a partly submerged frame that receives buoyancy by pumping water out of three cylinders connected to the frame. Air is pumped into the cylinders in order to maintain a positive difference between the internal air-pressure and the external water-pressure: for any cylinder, this pressure-difference is possibly critical at certain regions located on the cylinder and on a spherical cupola on the top of it. Optimal pumping rates of water and air as a function of time are determined, such as to minimize the maximum of certain weighted pressure differences at the critical regions, and such as to satisfy given geometrical and dynamical boundary conditions.

  9. Un Algoritmo Evolutivo para Resolver el Problema de Coloración Robusta

    Directory of Open Access Journals (Sweden)

    Pedro Lara Velázquez

    2012-03-01

    Full Text Available Let G and \\bar{G} be two complementary graphs. Given a penalty function defined over the edges of \\bar{G}, it is said that the rigidity of a k-coloring of G is the summation ofthe penalties of the edges of G that join vertices whose endpoint are equally colored. Based on this previous definition, the Robust Coloring Problem is set when searching the valid k-coloring of minimum rigidity. Yáñez and Ramírez proved that this is an NP-hard problem. In this work we present an evolutive algorithm based in the scatter search technique, which obtains optimal solutions for those instances for which an optimal solution is known, and obtains the best known solutions compared to other heuristics, such as: simulated annealing, tabu search and partial enumeration.

  10. Source water quality shaping different fouling scenarios in a full-scale desalination plant at the Red Sea

    KAUST Repository

    Khan, Muhammad

    2013-02-01

    The complexity of Reverse Osmosis (RO) membrane fouling phenomenon has been widely studied and several factors influencing it have been reported by many researchers. This original study involves the investigation of two different fouling profiles produced at a seawater RO desalination plant installed on a floating mobile barge. The plant was moved along the coastline of the Red Sea in Saudi Arabia. The two locations where the barge was anchored showed different water quality. At the second location, two modules were harvested. One of the modules was pre-fouled by inorganics during plant operation at the previous site while the other was installed at the second site. Fouled membranes were subjected to a wide range of chemical and microbiological characterization procedures. Drastically different fouling patterns were observed in the two membranes which indicates the influence of source water quality on membrane surface modification and on fouling of RO membranes. © 2012 Elsevier Ltd.

    Coal has been known as one of energy alternatives that has been used as energy source for several power plants in Indonesia. During its transportation from coal sites to power plant locations is required the eligible shipping line services that are able to provide the best freight rate. Therefore, this study aims to obtain the standardized formulations for determining the ocean freight especially for coal distribution based on the theoretical concept. The freight calculation model considers three alternative transport modes commonly used in coal distribution: tug-barge, vessel and self-propelled barge. The result shows there are two cost components very dominant in determining the value of freight with the proportion reaching 90% or even more, namely: time charter hire and fuel cost. Moreover, there are three main factors that have significant impacts on the freight calculation, which are waiting time at ports, time charter rate and fuel oil price.

    We present the calculation of the impact factor for the γ (∗) →qq-barg transition within Balitsky’s high energy operator expansion. We also rederive the impact factor for the γ (∗) →qq-bar transition within the same framework. These results provide the necessary building blocks for further phenomenological studies of inclusive diffractive deep inelastic scattering, as well as, for two and three jets diffractive production, which go beyond approximations discussed in the literature.

    We show that the dynamics of the quark - gluon plasma is such that during hadronization the creation of hybrids will predominate over the creation of mesons, giving a novel signature of the existence of QGP. At T=0 the qq-barg hybrids are known to decay strongly into a pair of mesons. We find that at temperatures relevant to the QGP, this channel is forbidden. This would lead to significant modifications of the photonic signals of the QGP. (author)

    2004-07-01

    Recently, testing was needed on production wells in East Kalimantan. The wells were in a mature field, and productivity from the wells field featured high water cut (WC) and extremely high gas-volume fractions (GVF). The WC and GVF ranged from 80 to 100% and 90 to 100%, respectively. Moreover, most of the wells are low productivity so they are very sensitive to back-pressure. The high WC, high GVF and low-productivity from these wells in this area present an extreme challenge for accurate production measurement. Barges are commonly used to perform well services in the swamp area of this marginal field, and production allocations from wells in this difficult area were previously monitored and measured with conventional well-test equipment on-board a well testing barge. The well test equipment traditionally used requires a large footprint, and the associated flaring presents an environmental situation in this sensitive swamp area. Hence, the MPFM solution was chosen. To better meet the challenges presented by the testing conditions, a portable multiphase flow meter (MPFM) was chosen to perform the testing from the well-testing barge. For comparative purposes, the MPFM was installed on the barge immediately upstream of the well testing equipment. Initial measurements with the MPFM yielded results that were {+-} 30% of the test separator reading. A slight modification was introduced to the MPFM system in the form of a gas knock-out (GKO) vessel. Subsequent measurements with the modified MPFM system yielded readings that were {+-}10% of the test separator reading. (author)

  7. Energy intensity, life-cycle greenhouse gas emissions, and economic assessment of liquid biofuel pipelines.

    Science.gov (United States)

    Strogen, Bret; Horvath, Arpad; Zilberman, David

    2013-12-01

    Petroleum fuels are predominantly transported domestically by pipelines, whereas biofuels are almost exclusively transported by rail, barge, and truck. As biofuel production increases, new pipelines may become economically attractive. Location-specific variables impacting pipeline viability include construction costs, availability and costs of alternative transportation modes, electricity prices and emissions (if priced), throughput, and subsurface temperature. When transporting alcohol or diesel-like fuels, pipelines have a lower direct energy intensity than rail, barge, and trucks if fluid velocity is under 1 m/s for 4-inch diameter pipelines and 2 m/s for 8-inch or larger pipelines. Across multiple hypothetical state-specific scenarios, profit-maximizing design velocities range from 1.2 to 1.9 m/s. In costs and GHG emissions, optimized pipelines outperform trucks in each state and rail and barge in most states, if projected throughput exceeds four billion liters/year. If emissions are priced, optimum design diameters typically increase to reduce pumping energy demands, increasing the cost-effectiveness of pipeline projects. Copyright © 2013 Elsevier Ltd.

  8. Overview of the environmental concerns of coal transportation

    Energy Technology Data Exchange (ETDEWEB)

    1980-02-01

    More than 30 environmental concerns were analyzed for the transportation of coal by rail, roads (trucks), high voltage transmission lines (that is, from mine-mouth generating plants to distribution networks), coal slurry pipelines, and barges. The following criteria were used to identify these problems: (1) real physical environmetal impacts for which control technologies must be developed, or regulation made effective where control technologies presently exist; (2) the level of impact is uncertain, although the potential impact may be moderate to high; (3) the concerns identified by the first two criteria are specific to or exacerbated by coal transportation. Generic transportation problems are not included. The significant environmental problems identified as a result of this study are: (1) rail transport - community traffic disruption and human health, safety, and habitat destruction; (2) coal haul roads - road degradation, traffic congestion and safety, air quality, and noise; (3) high voltage transmission lines - changed land use without local benefits, biological health and safety effects, and disruption of world weather patterns; (4) slurry pipelines - water availability, water quality, and possible spills from non-water slurry pipelines; and (5) barge transport - impacts common to all barge traffic.

    Full Text Available Sebagai jalur alternatif jalan khusus,  melalui transportasi sungai Lematang dengan perancangan kapal pengangkut hasil tambang dalam  distribusi batubara merupakan salah satu solusi untuk jalur darat provinsi tetap terjaga dengan baik dan tidak terjadi kemacetan akibat konvoi dump truk pengangkut batubara. Bentuk geografis, perpindahan aliran sungai, dan pendangkalan sungai Lematang berpengaruh terhadap sulitnya membuat kapal angkut batubara melalui sistem tranportasi sungai tersebut. Jika menggunakan kapal angkut batubara jenis Tug and Barge, maka akan menyebabkan kesulitan dalam proses manouvering kapal bahkan sering terjadi kapal kandas karena pendangkalan sungai, serta bisa juga kapal tersangkut bagian barge karena sudut olah belok kapal terlalu melebar. Disamping itu juga, perlu diperhatikan bentuk aliran sungai Lematang yang melengkung dan berkelok, adanya masalah sosial, serta hambatan lain seperti adanya kabel slink, jembatan, kedalaman sungai, sampah kayu d.l.l. Salah satu teknologi yang bisa digunakan adalah kapal SPB (Self Propeller Barge. Dimana kapal SPB pengangkut batubara memiliki kelebihan dapat manouvering yang baik ketika melintasi wilayah sungai. Kapal SPB pengangkut batubara memiliki geladak angkut yang terletak dibelakang akomodasi, hal ini akan mempermudah jarak pandang dan proses manouvering kapal, akan tetapi terbatas dengan kapasitas yang diangkut karena terbatas dengan kedalaman draft kapal yang dimiliki. Dalam perancangan harus diperhatikan faktor geografis, kedalaman sungai, faktor sosial dan faktor ekonomis kapal. Sehingga akan memberikan hasil teknologi kapal SPB pengangkut batubara dengan kondisi sellow draft yang efektif dan efisien. Dimana kapal SPB yang dirancang dengan kaasitas 200 ton setara dengan 20 dump truk, kapal  yang difungsikan untuk mengangkut batubara dengan memiliki kecepatan sebesar 12 knot (dengan mesin 2x250HP dan konsumsi bahan bakar sebesar 1.77 ton dengan mngunakan SFOC sebesar 160 gram

    RADTRAN 5 is a computer code developed at Sandia National Laboratories (SNL) in Albuquerque, NM, to estimate radiological and nonradiological risks of radioactive materials transportation. RADTRAN 5 is written in ANSI Standard FORTRAN 77 and contains significant advances in the methodology for route-specific analysis first developed by SNL for RADTRAN 4 (Neuhauser and Kanipe, 1992). Like the previous RADTRAN codes, RADTRAN 5 contains two major modules for incident-free and accident risk amlysis, respectively. All commercially important transportation modes may be analyzed with RADTRAN 5: highway by combination truck; highway by light-duty vehicle; rail; barge; ocean-going ship; cargo air; and passenger air

  14. A floating desalination/co-generation system using the KLT-40 reactor and Canadian RO desalination technology

    2000-01-01

    As the global consumption of water increases with growing populations and rising levels of industrialization, major new sources of potable water production must be developed. To address this issue efficiently and economically, a new approach has been developed in Canada for the integration of reverse osmosis (RO) desalination systems with nuclear reactors as an energy source. The resulting nuclear desalination/cogeneration plant makes use of waste heat from the electrical generation process to preheat the RO feedwater, advanced feedwater pre-treatment and sophisticated system design integration and optimization techniques. These innovations have led to improved water production efficiency, lower water production costs and reduced environmental impact. The Russian Federation is developing the KLT-40 reactor for application as a Floating Power Unit (FPU). The reactor is ideally suited for such purposes, having bad many years of successful operation as a marine propulsion reactor aboard floating nuclear powered icebreakers and other nuclear propelled vessels. Under the terms of a cooperation agreement with the Russian Federation Ministry of Atomic Energy, CANDESAL Enterprises Ltd has evaluated the FPU, containing two KLT-40 reactors, as a source of electrical energy and waste heat for RO desalination. A design concept for a floating nuclear desalination complex consisting of the FPU and a barge mounted RO desalination unit has been analyzed to establish preliminary performance characteristics for the complex. The FPU, operating as a barge mounted electrical generating station, provides electricity to the desalination barge. In addition, the condenser cooling water from the FPU is used as a source of preheated feedwater for the RO system on the desalination barge. The waste heat produced by the electrical generating process is sufficient to provide RO feedwater at a temperature of about 10 deg. C above ambient seawater temperature. Preliminary design studies have

    ...The Coast Guard is changing the existing regulated navigation area in the navigable waters of New Haven Harbor, Quinnipiac River and Mill River. The current RNA pertains only to the operation of tugs and barges. The changes allow periodic, temporary closure of the area which will be needed during construction of the new Pearl Harbor Memorial Bridge, and which could be needed at other times as well. This revision allows the Coast Guard to suspend all vessel traffic through the RNA during periods of temporary closure. This rule is necessary to provide for the safety of life in the regulated area.

    1979-04-01

    This review effort was undertaken to clarify and, if possible, quantify the issues surrounding the thermal input into the lower Des Plaines River from the Commonwealth Edison Joliet Electrical Generation Facility. The central issue is whether or not a reduction of the thermal discharge from the facility would produce beneficial environmental effects. This issue is clouded due to the fact of a number of environmental problems. These problems include: the river water quality, sediment quality, and barge traffic impacts. These variables, coupled with the uncertain future stream volume and conflicting data, prevent any simplistic conclusions from being drawn. Thus, any short-term study can only result in an overview of the situation.

    The authors show that psi → γγrho and γγphi can test the glue or qq-bar content of iota(1440). If iota is a glueball then psi → γγphi and psi → γγrho will show similar distributions in the γV invariant mass; if iota contains qq-bar then γphi and γrho distributions will differ. The possibility of identifying hybrid qq-barg states via electromagnetic transitions such as psi → γH → γγV and γγ → Hsub(n) is debated. (author)

    Full Text Available Let $G$ and $\\bar{G}$ be complementary graphs. Given a penalty function defined on the edges of $G$, we will say that the rigidity of a $k$-coloring of $G$ is the sum of the penalties of the edges of G joining vertices of the same color. Based on the previous definition, the Robust Coloring Problem (RCP is stated as the search of the minimum rigidity $k$-coloring. In this work a comparison of heuristics based on simulated annealing, GRASP and scatter search is presented. These are the best results for the RCP that have been obtained.

  1. From Apollo to Cognac

    1980-01-01

    Shell Oil Company started oil and gas production from a new offshore platform called Cognac located in the Gulf of Mexico. It is the world's tallest oil platform, slightly taller than the Empire State Building. The highly complex job of installing Cognac's support "jacket" under water more than a thousand feet deep was directed from a barge-based control center. To enable crews to practice in advance difficult tasks never before accomplished, Honeywell, adapting NASA's Apollo technology, developed a system for simulating the various underwater operations. In training sessions, displays and controls reacted exactly as they would in real operation.

    1993-03-01

    A rail routine model, INTERLINE, has been developed at the Oak Ridge National Laboratory to investigate potential routes for transporting radioactive materials. In Version 5.0, the INTERLINE routing algorithms have been enhanced to include the ability to predict alternative routes, barge routes, and population statistics for any route. The INTERLINE railroad network is essentially a computerized rail atlas describing the US railroad system. All rail lines, with the exception of industrial spurs, are included in the network. Inland waterways and deep water routes along with their interchange points with the US railroadsystem are also included. The network contains over 15,000 rail and barge segments (links) and over 13,000 stations, interchange points, ports, and other locations (nodes). The INTERLINE model has been converted to operate on an IBM-compatible personal computer. At least a 286 computer with a hard disk containing approximately 6 MB of free space is recommended. Enhanced program performance will be obtained by using arandom-access memory drive on a 386 or 486 computer

    Full Text Available Nowadays the problem of the spectators is the most important and hard one to confront. We see that the regular spectator is not that much lively and surely not that much loyal, therefore we go towards young spectators. It is true that the younger the spectator, the more vivid and spontaneous his reactions are and it is also true that what keeps the youth away from theatre is bad theater. Willing to have more spectators we often find ourselves trying in diferent ways, such as: you should come tonight, it will be fun...In one way all kinds of seductions towards the spectators flirt dangerously with the same proposal- come and be part of the good life, which is good and so must be because it contains the best. The thing is not just to attract the spectator, that is not enough. The hardest part is to create works that breed in him undeniable hunger and thirst. To what point does the form accept the artificiality? This is one of the biggest problem we barge today and will barge for a long time. By approving to ourselves the grotesque masks, exaggerated make-up, precious costumes, declamations, borrowed movements from ballet, we will never get out of the routine of traditional theatral art.

    Full Text Available Abstract Background The emergence of agriculture about 10,000 years ago marks a dramatic change in human evolutionary history. The diet shift in agriculture societies might have a great impact on the genetic makeup of Neolithic human populations. The regionally restricted enrichment of the class I alcohol dehydrogenase sequence polymorphism (ADH1BArg47His in southern China and the adjacent areas suggests Darwinian positive selection on this genetic locus during Neolithic time though the driving force is yet to be disclosed. Results We studied a total of 38 populations (2,275 individuals including Han Chinese, Tibetan and other ethnic populations across China. The geographic distribution of the ADH1B*47His allele in these populations indicates a clear east-to-west cline, and it is dominant in south-eastern populations but rare in Tibetan populations. The molecular dating suggests that the emergence of the ADH1B*47His allele occurred about 10,000~7,000 years ago. Conclusion We present genetic evidence of selection on the ADH1BArg47His polymorphism caused by the emergence and expansion of rice domestication in East Asia. The geographic distribution of the ADH1B*47His allele in East Asia is consistent with the unearthed culture relic sites of rice domestication in China. The estimated origin time of ADH1B*47His allele in those populations coincides with the time of origin and expansion of Neolithic agriculture in southern China.

    It is recognized that deep water offshore oil exploitation activities requires the use of sophisticated computational tools to predict the behavior of floating offshore systems under the action of environmental loads. These computational tools should be able to perform coupled dynamic analyses, considering the non-linear interaction of the hydrodynamic behavior of the platform with the structural/hydrodynamic behavior of the mooring lines and risers, represented by Finite Element models. The use of such a sophisticated computational tool becomes mandatory not only for the design of production platforms, but also for the simulation of offshore installation operations. For instance, in the installation of submarine pipelines, the wall thickness design may not be governed by the pressure containment requirements of the pipeline during the operation, but by the installation process, specifically the combined action of bending, tension and hydrostatic pressure acting on the pipeline, that is also submitted to the motions of the lay barge. Therefore, the objective of this work is to present the results of numerical simulations of S-lay installation procedures using a computational tool that performs dynamic analysis coupling the structural behavior of the pipe with the hydrodynamic behavior of the vessel motions under environmental conditions. This tool rigorously considers the contact between the pipeline and its supports (lay barge, stinger, seabed). The results are compared to traditional pipe laying simulations based on RAO motions.

    Eesti Gaas has experienced several operational difficulties with regard to the high pressure distribution stations in Estonia. Metering systems are unreliable, preheating is performed using open fire gas heaters, the pressure reduction valves are unreliable because of wear and tear, and odorization takes place via buried storage tanks. The conclusion is that the existing M/R stations involves safety and environmental problems. For that reason, Eesti Gaas has initiated modernization of the M/R stations. The Danish Energy Agency, environmental energy sector programme, has granted financial aids for the purpose of assisting Eesti Gass with the modernization of the M/R stations. The purpose of this design study is to prepare a basic design for a 55 barg to 3 barg M/R station. In agreement with Eesti Gaas, the design shall cover two different station sizes, one with a maximum flow rate of 2.000 Nm{sup 3}/hr, and one with a maximum flow rate of 10.000 Nm{sup 3}/hr. It is the intention, that the present Basic Design Report may be used as basis for preparation of tender material in the form of a detailed design prepared by a local company. (EG)

    1996-01-01

    A method to identify and differentiate spilled oil and petroleum products was developed. In January 1996, four birds covered with an unknown oil were found near Larchipel-de-Mingan National Park in Quebec. Environment Canada wanted to know if the oil came from a leak in a barge which was grounded on Anticosti Island. To do so, it was necessary to determine the nature of the oil, the type of petroleum hydrocarbons, the age, the weathering and degradation extent of the spilled oil, and changes in oil character since the occurrence of any possible spill. The analytical approach to determine the source of the unknown oil was described. The analysis of individual aliphatic, aromatic, and biomarker hydrocarbons were made with the use of gas chromatography/mass spectroscopy (GC/MS), and gas chromatography/flame ionization detector (GC/FID). Pattern recognition plot analysis was also used in determining the source of the oil. It was concluded that the residual oil on the birds was not from the suspected barge oil, and was most probably old, highly weathered, somewhat biodegraded bunker type oil. 23 refs., 5 tabs., 7 figs

    The US Coast Guard commissioned Pacific Northwest Laboratory (PNL) to conduct this study of 45 self-help oil-spill response techniques and equipment for oceangoing tankers and inland tank barges to assess the potential effectiveness of the proposed countermeasure categories. This study considers the hypothetical outflow of oil in the case of side damage and bottom damage to single-hull designs. The results will be considered by the Coast Guard in drafting regulations pertaining to the requirement for tanker vessels to carry oil pollution response equipment (i.e., in response to the oil Pollution Act of 1990). PNL's approach to this investigation included: assessing time-dependent oil outflow in the cases of collision and grounding of both tankers and barges; identifying environmental constraints on self-help countermeasure operation; identifying human factor issues, such as crew performance, safety, and training requirements for the self-help countermeasures considered; and assessing each self-help countermeasure with respect to its potential for minimizing oil loss to the environment. Results from the time-dependent oil outflow, environmental limitations, and human factors requirements were input into a simulation model.

    2017-07-01

    Fuel costs and emissions in maritime ports are an opportunity for transportation energy efficiency improvement and emissions reduction efforts. Ocean-going vessels, harbor craft, and cargo handling equipment are still major contributors to air pollution in and around ports. Diesel engine costs continually increase as tighter criteria pollutant regulations come into effect and will continue to do so with expected introduction of carbon emission regulations. Diesel fuel costs will also continue to rise as requirements for cleaner fuels are imposed. Both aspects will increase the cost of diesel-based power generation on the vessel and on shore. Although fuel cells have been used in many successful applications, they have not been technically or commercially validated in the port environment. One opportunity to do so was identified in Honolulu Harbor at the Young Brothers Ltd. wharf. At this facility, barges sail regularly to and from neighbor islands and containerized diesel generators provide power for the reefers while on the dock and on the barge during transport, nearly always at part load. Due to inherent efficiency characteristics of fuel cells and diesel generators, switching to a hydrogen fuel cell power generator was found to have potential emissions and cost savings.

    This paper presents an alternative way, using an auxiliary submersible structure, to install manifolds or subsea equipment transported to the location by an AHTS or an auxiliary barge. The objective of the structure is to positioning the manifold at the sea water level and make the deployment feasible without the use of large barges with high load capacity or specific vessel equipped with high load A-frame. The structure is towed and positioned by an AHTS or auxiliary vessel and does not have any energy source, propulsion, embarked crew or storage tank for combustible. All these things are at the towed vessel. The manifold uplift is performed by a hydraulic crane positioned at the top of the structure, or by buoyancy pontoons. The manifold also could be suspended by the supply crane. The submersible structure is designed using the modular concept, to facilitate the assembly and transportation. Pipes, connections and all other structure accessories are classified accordingly with the mechanic loads on the structure. (author)

    Gutnick, D.L.

    1991-11-01

    An assessment is presented of the scientific and technological developments in the area of bioremediation and biodegradation of marine oil pollution. A number of allied technologies are also considered. The basic technology in bioremediation involves adding fertilizers to an oil spill to enhance the natural process of oil biodegradation. Bioremediation can be applied to open systems such as beach or land spills, or in closed and controlled environments such as storage containers, specially constructed or modified bioreactors, and cargo tanks. The major advantage of using closed environments is the opportunity to control the physical and nutritional parameters to optimize the rate of biodegradation. An evaluation of the state of the art of bioremediation in Canada is also included. Recommendations are made to involve the Canadian Transportation Development Centre in short-term research projects on bioremediation. These projects would include the use of a barge as a mobile bioreactor for the treatment of off-loaded oily waste products, the use of in-situ bioremediation to carry out extensive cleaning, degassing, and sludge remediation on board an oil tanker, and the use of a barge as a mobile bioreactor and facility for the bioremediation of bilges. 51 refs., 4 figs., 14 tabs

    For nearly a decade, dredged material from San Francisco Bay has been deposited at the U.S. Environmental Protection Agency (EPA) Region IX designated disposal site on the continental slope west of the Farallon Islands. Over the past several years, annual disposal volumes have ranged from 136,170 m3 (61 barge loads) to 2,407,600 m3 (1,173 barge loads) (Ota, personal communication, 2000). The EPA has conducted extensive studies to evaluate the fate and effects of the disposed material (Abdelrhman, 1992; Tetra-Tech, 1992; SAIC, 1992). The EPA has also maintained a long-term monitoring program to collect hydrodynamic, sedimentary, chemical, and biological data that are used to determine whether the dredged material adversely affects the ecology of adjacent water bodies and whether it moves from the disposal site, especially into the Gulf of the Farallones National Marine Sanctuary. As part of this monitoring program, the U.S. Geological Survey (USGS) Coastal and Marine Geology Program (CMGP) deployed arrays of instruments on three moorings near the EPA disposal site from November 1997 to November 1998. This report describes the results and findings of this field monitoring experiment.

  20. Offshore Cable Installation - Lillgrund. Lillgrund Pilot Project

    Energy Technology Data Exchange (ETDEWEB)

    Unosson, Oscar (Vattenfall Vindkraft AB, Stockholm (Sweden))

    2009-01-15

    This report describes the installation method and the experiences gained during the installation of the submarine cables for the offshore wind farm at Lillgrund. The wind farm consists of 48 wind turbines and is expected to produce 0.33 TWh annually. Different aspects of the installation, such as techniques, co-operation between the installation teams, weather conditions and regulatory and environmental issues are described in this report. In addition, recommendations and guidelines are provided, which hopefully can be utilised in future offshore wind projects. The trenches, in which the submarine cables were laid, were excavated weeks before the cable laying. This installation technique proved to be successful for the laying of the inter array cables. The export cable, however, was laid into position with difficulty. The main reason why the laying of the export cable proved more challenging was due to practical difficulties connected with the barge entrusted with the cable laying, Nautilus Maxi. The barge ran aground a number of times and it had difficulties with the thrusters, which made it impossible to manoeuvre. When laying the inter array cables, the method specification was closely followed, and the laying of the cables was executed successfully. The knowledge and experience gained from the offshore cable installation in Lillgrund is essential when writing technical specifications for new wind plant projects. It is recommended to avoid offshore cable installation work in winter seasons. That will lower the chances of dealing with bad weather and, in turn, will reduce the risks

    This report contains an analytical examination of cargo spill and fire hazard potential associated with the marine handling of liquefied petroleum gas (LPG) as cargo. Principal emphasis was on cargo transfer operations for ships unloading at receiving terminals, and barges loading or unloading at a terminal. Major safety systems, including emergency shutdown systems, hazard detection systems, and fire extinguishment and control systems were included in the analysis. Spill probabilities were obtained from fault tree analyses utilizing composite LPG tank ship and barge designs. Failure rates for hardware in the analyses were generally taken from historical data on similar generic classes of hardware, there being very little historical data on the specific items involved. Potential consequences of cargo spills of various sizes are discussed and compared to actual LPG vapor cloud incidents. The usefulness of hazard mitigation systems (particularly dry chemical fire extinguishers and water spray systems) in controlling the hazards posed by LPG spills and spill fires is also discussed. The analysis estimates the probability of fatality for a terminal operator is about 10/sup -6/ to 10/sup -5/ per cargo transfer operation. The probability of fatality for the general public is substantially less.

    A rail routine model, INTERLINE, has been developed at the Oak Ridge National Laboratory to investigate potential routes for transporting radioactive materials. In Version 5.0, the INTERLINE routing algorithms have been enhanced to include the ability to predict alternative routes, barge routes, and population statistics for any route. The INTERLINE railroad network is essentially a computerized rail atlas describing the US railroad system. All rail lines, with the exception of industrial spurs, are included in the network. Inland waterways and deep water routes along with their interchange points with the US railroadsystem are also included. The network contains over 15,000 rail and barge segments (links) and over 13,000 stations, interchange points, ports, and other locations (nodes). The INTERLINE model has been converted to operate on an IBM-compatible personal computer. At least a 286 computer with a hard disk containing approximately 6 MB of free space is recommended. Enhanced program performance will be obtained by using arandom-access memory drive on a 386 or 486 computer.

    The compressed air system becomes part of a very important utility system in a Plant, including the Steam Power Plant. In PLN’S coal fired power plant, Paiton units 1 and 2, there are four Centrifugal air compressor types, which produce compressed air as much as 5.652 cfm and with electric power capacity of 1200 kW. Electricity consumption to operate centrifugal compressor is 7.104.117 kWh per year. Compressed air generation is not only sufficient in quantity (flow rate) but also meets the required air quality standards. compressed air at Steam Power Plant is used for; service air, Instrument air, and for fly Ash. This study aims to measure some important parameters related to air quality, followed by potential disturbance analysis, equipment breakdown or reduction of energy consumption from existing compressed air conditions. These measurements include counting the number of dust particles, moisture content, relative humidity, and also compressed air pressure. From the measurements, the compressed air pressure generated by the compressor is about 8.4 barg and decreased to 7.7 barg at the furthest point, so the pressure drop is 0.63 barg, this number satisfies the needs in the end user. The measurement of the number of particles contained in compressed air, for particle of 0.3 micron reaches 170,752 particles, while for the particle size 0.5 micron reaches 45,245 particles. Measurements of particles conducted at several points of measurement. For some point measurements the number of dust particle exceeds the standard set by ISO 8573.1-2010 and also NACE Code, so it needs to be improved on the air treatment process. To see the amount of moisture content in compressed air, it is done by measuring pressure dew point temperature (PDP). Measurements were made at several points with results ranging from -28.4 to 30.9 °C. The recommendation of improving compressed air quality in steam power plant, Paiton unit 1 and 2 has the potential to extend the life of

    Since 1995, the Confederated Tribes of the Colville Reservation (Colville Confederated Tribes) have managed the Chief Joseph Kokanee Enhancement Project as part of the Northwest Power Planning Council (NWPPC) Fish and Wildlife Program. Project objectives have focused on understanding natural production of kokanee (a land-locked sockeye salmon) and other fish stocks in the area above Grand Coulee and Chief Joseph Dams on the Columbia River. A 42-month investigation concluded that entrainment at Grand Coulee Dam ranged from 211,685 to 576,676 fish annually. Further analysis revealed that 85% of the total entrainment occurred at the dam's third powerplant. These numbers represent a significant loss to the tribal fisheries upstream of the dam. In response to a suggestion by the NWPPC Independent Scientific Review Panel, the scope of work for the Chief Joseph Kokanee Enhancement Project was expanded to include a multiyear pilot test of a strobe light system to help mitigate fish entrainment. This report details the work conducted during the second year of the study by researchers of the Colville Confederated Tribes in collaboration with the Pacific Northwest National Laboratory. The 2002 study period extended from May 18 through July 30. The objective of the study was to determine the efficacy of a prototype strobe light system to elicit a negative phototactic response in kokanee and rainbow trout. The prototype system consisted of six strobe lights affixed to an aluminum frame suspended vertically underwater from a barge secured in the center of the entrance to the third powerplant forebay. The lights, controlled by a computer, were aimed to illuminate a specific region directly upstream of the barge. Three light level treatments were used: 6 of 6 lights on, 3 of 6 lights on, and all lights off. These three treatment conditions were applied for an entire 24-hr day and were randomly assigned within a 3-day block throughout the study period. A seven

    A study has been performed to examine the contingencies that could be pursued by the Department of Energy's (DOE's) Office of Civilian Radioactive Waste Management (OCRWM) for shipping spent fuel beginning in 1998. OCRWM's current plan is to initiate operations using early production units of Initiative I truck and rail/barge casks that are presently being designed. Contingencies to this plan were considered in case some unforeseen event occurs that precludes the Initiative I casks from entering into service early in 1998 in sufficient quantities (both numbers and types) to satisfy DOE's shipping needs. Specifically, the study addressed the potential availability of cask systems, selected several cask usage scenarios, determined the requirements for casks under these scenarios, generically assessed different strategies for acquiring casks or the use of casks, and generically assessed cask fabrication capabilities. Issues concerning both domestic and foreign resources were addressed with a focus on the first five years of Federal Waste Management System (FWMS) operation

    The dynamic responses of mooring line serve important functions in the station keeping of a floating wind turbine (FWT). Mooring line damping significantly influences the global motions of a FWT. This study investigates the estimation of mooring line damping on the basis of the National Renewable Energy Laboratory 5 MW offshore wind turbine model that is mounted on the ITI Energy barge. A numerical estimation method is derived from the energy absorption of a mooring line resulting from FWT motion. The method is validated by performing a 1/80 scale model test. Different parameter changes are analyzed for mooring line damping induced by horizontal and vertical motions. These parameters include excitation amplitude, excitation period, and drag coefficient. Results suggest that mooring line damping must be carefully considered in the FWT design.

    The Russian Shipyard ''Zvyozdochka'' has designed a new container for transportation and storage of solid radioactive wastes. The PST1A-6 container is cylindrical shaped and it can hold seven standard 200-liter (55-gallon) drums. The steel wall thickness is 6 mm, which is much greater than standard U.S. containers. These containers are fully certified to the Russian GOST requirements, which are basically identical to U.S. and IAEA standards for Type A containers. They can be transported by truck, rail, barge, ship, or aircraft and they can be stacked in 6 layers in storage facilities. The first user of the PST1A-6 containers is the Northern Fleet of the Russian Navy, under a program sponsored jointly by the U.S. DoD and DOE. This paper will describe the container design and show how the first 400 containers were fabricated and certified

    On June 23, 1989, the outbound tanker ship Rachel-B and the towboat Gayolyn Ann Griffin, towing barges owned by Coastal Towing, collided in the northern end of the Houston Sip Channel near its confluence with the Bayport Channel. The collision resulted in a spill of approximately 6,000 barrels of slurry oil into upper Galveston Bay. This paper reports that the U.S. Coast Guard assumed the role of on-scene coordinator. Several State agencies were involved in the various on-site activities. The Texas Water Commission (TWC), as the State's lead agency in spill response, closely monitored the spill and cleanup activities. Despite the efforts of all the aforementioned agencies, the weather ultimately directed spill response activities as it became readily apparent that the eye of Tropical Storm Allison would pass near the site of the spill

    Seabottom sediments from a discontinued Philadelphia-Camden 40-Mile ocean sewage disposal site were cultured for cyst-forming free-living amoebae. Barge delivered wastes were discharged at the site from 1973 until 1980 when the site was closed. One station at the southeast margin of the site was sampled at a depth of approximately 50 m, twice in 1978 and once in 1982, 1983 and 1984. Sediment from the 1978 collection yielded Acanthamoeba polyphaga, Vahlkampfia sp., and an unknown amoeba with stellate endocysts similar to those of A. astronyxis. Trophozoites and cysts of the isolate were typical of those described for the genus Acanthamoeba. Biochemical tests employing enzyme electrophoresis and morphological studies on live and stained specimens showed that the isolate was distinct from other well-described species within the family Acanthamoebidae Sawyer & Griffin, 1975.

After reading a paper by MONTUORI (2005, I considered how literature reviews could be situated systemically whereby connections and relatedness between people and ideas are identified. This opened up possibilities for me that were transformative, re-positioning a process that I had previously seen as positivist, to one which is connected to a systemic position (BARGE, 2006. In this article, I discuss how I conduct literature reviews from a systemic position; each text speaking to the others as in conversation, identifying themes, connections and generating new knowledge. The concept of texts "speaking" to each other lends itself to a dialogical approach. I will discuss how the systemic, dialogical and ethical considerations should be made.

    Full Text Available In France, most tunnel canals were built during the 19th and 20th centuries. Maintaining them is not only a matter of heritage preservation but also a question of security. Inspecting tunnel canals is difficult and time consuming, which motivates the development of an image-based surveying system, as already exists for railway or road tunnels. However, while the imaging configuration is similar, referencing the data acquisition device is more difficult in the case of underground waterways, due to the drifts of the inspection barge. In this paper, we introduce the recording prototype we have designed and report the results of the test that were performed in an underground waterway, Niderviller's tunnel, to assess the feasibility of the system. In particular, we give details on the imaging system design. We also analyze the pros and cons of each location method, in terms of costs, practicability, computational burden and accuracy.

    Samples taken from Marrow Marsh in Galveston Bay, Texas were taken to assess the efficacy of the August 5, 1990 bioremediation treatment in the marsh following the Apex barges oil spill on July 28, 1990. The bioremediation treatment combined a lyophilized bacterial mixture and a nutrient mix containing phosphorus and nitrogen. Samples from the marsh had been collected over a 96 h period from both treated and untreated oiled sites. Oil fingerprinting, fatty acid analysis, polynuclear aromatic hydrocarbons analysis, and total petroleum hydrocarbons analysis were performed to evaluate changes in the chemical characteristics of spilled oil. Results of analyses, although not statistically reliable, failed to support the occurrence of any definite chemical alteration in the spilled oil that could be attributed to the bioremediation treatment. The relatively short sampling period and the number of samples taken, however, may have been insufficient to document the efficacy of the overall bioremediation effect. 13 refs., 6 figs., 4 tabs

    2016-07-01

    In most large port cities, the challenge of inter-terminal transfers (ITT) prevails due to the long distance between multiple terminals. The quantity of containers requiring movement between terminals as they connect from pre-carrier to on-carrier is increasing with the formation of the mega-alliances. The paper proposes a continuous time mathematical programming model to optimize the deployment and schedule of trucks and barges to minimize the number of operating transporters, their makespan, costs and the distance travelled by the containers by choosing the right combination of transporters and container movements while fulfilling time window restrictions imposed on reception of the containers. A multi-step routing problem is developed where transporters can travel from one terminal to another and/or load or unload containers from a specific batch at each step. The model proves successful in identifying the costless schedule and means of transportation. And a sensibility analysis over the parameters used is provided. (Author)

    According to the National Coal Association, an average of 105 million tons of coal per year are moved by truck in the USA to their field destination. Hundreds of millions of tons are also moved by truck to preparation plants, rail depots and barge docks for movement beyond. Savage Industries Inc., which describes itself as a leader in the transport of coal by road, moves some 30 million tons per year of coal, lignite, petroleum coke, waste coal and other products, operating in 15 stages. This article briefly describes some recent advances in truck design and discusses weight laws and truck axle configurations which vary greatly across the United States. Coal volumes moved by trucks are likely to increase over the next few years and the article briefly lists some of the new markets for coal transport which may emerge. 1 photo.

    This document discusses the functions that are required to accept the waste, transport the waste, and provide the mandatory support activities. These functions are independent of any organizational structure and reflect a conventional and generally accepted transportation system involving casks; ancillary equipment; truck, rail, and barge transporters; cask and vehicle maintenance facilities; traffic management activities; and other related support system subelements. Where appropriate, the functions are ordered to identify their relationship with each other. This relationship is depicted graphically in functional flow block diagrams (FFBDs). The FFBDs provide a definition of the functions that the systems must perform; a tool to aid in the identification of important issues and trade-off studies; an important method for tracing requirements and decisions back to essential functions; and a basis for allocating the functions, a process that will identify where, how, and by whom they will be performed. 22 refs., 13 figs.

    Global trade and commerce requires products to be securely contained and transferred in a timely way across great distances and between national boundaries. Throughout the process, cargo and containers are stored, handled and checked by a range of authorities and authorised agents. Intermodal transportation involves the use of container ships, planes, railway systems, land bridges, road networks and barges. This paper examines the the nefarious nature of intentional disruption and nefarious risks associated with the movement of cargo and container freight. The paper explores main threats, vulnerabilities and security measures relevant to significant intermodal transit risk issues such as theft, piracy, terrorism, contamination, counterfeiting and product tampering. Three risk and vulnerability models are examined and basic standards and regulations that are relevant to safe and secure transit of container goods across international supply networks are outlined.

    1988-01-01

    Shippingport Station Decommissioning Project is the removal and shipment the Reactor Pressure Vessel (PRV) and its associated Neutron Shield Tank (NST) to the government owned Hanford Reservation in Richland, Washington. Engineering studies considered the alternatives for removal and shipment of the RPV/NST. These included segmentation for subsequent truck shipments, and one-piece removal with barge or rail shipment. Although the analysis indicated that current technology could be utilized to accomplish either alternative, one-piece removal of the RPV was selected as the safest, most cost effective method. When compared to segmentation, it was estimated that one-piece removal would reduce the duration of the Project by 1 year, reduce cost by $4 M, and result in a savings of radiation exposure of 150 man-Rem. Rail transportation of an integral RPV/NST package is not feasible due to the physical size of the package. 5 refs., 1 fig

    2001-01-01

    Conditions in Guatemala's Rio Dulce National Park (RDNP) present an immediate decision-making challenge concerning the reversal of current destructive environmental trends, and in establishing policies for restoration, protection, and sustainable use. This article summarises results of environmental assessment activities undertaken at three levels: an environmental impact assessment (EIA) of a proposed industrial forestry activity, an environmental assessment of management options for the Rio Dulce National Park, and water management planning for the Rio Dulce/Lago Izabal watershed. A key result of the EIA was to prohibit construction of a barge terminal within the boundaries of the park because it could set a precedent for future development. Management options for the park focused on establishing land-use controls, dealing with river transport more effectively, and identifying funding mechanisms to implement solutions. At the watershed scale, a strategic approach was recommended to identify priority issues for initiating change toward sustainability in the region. (author)

    In July 2008, the Global Threat Reduction Initiative and the IRT 2000 research reactor in Sofia, Bulgaria, operated by the Institute for Nuclear Research and Nuclear Energy (INRNE), safely shipped 6.4 kilograms of Russian origin highly enriched uranium (HEU) spent nuclear fuel (SNF) to the Russian Federation. The shipment, which resulted in the removal of all HEU from Bulgaria, was conducted by truck, barge, and rail modes of transport across two transit countries before reaching the final destination at the Production Association Mayak facility in Chelyabinsk, Russia. This paper describes the work, equipment, organizations, and approvals that were required to complete the spent fuel shipment and provides lessons learned that might assist other research reactor operators with their own spent nuclear fuel shipments.

  15. Transporting US oil imports: The impact of oil spill legislation on the tanker market

    International Nuclear Information System (INIS)

    1992-06-01

    This report looks at the impact of the Oil Pollution Act of 1990 and the developing State oil spill regulations on the tanker and coastal barge markets, and at the implications for the future of the U.S. seaborne petroleum trades. The analysis relied on a dual approach. Because much of the legislation, both State and Federal, is still evolving--particularly with respect to implementing regulations--as yet there can be no definitive assessment of its impact. Consequently a quantitative analysis of fleets, trades, and vessel movements, was complemented by extensive interviews. Discussions have been held with oil companies large and small, shipowners, charterers, insurance companies, classification societies, and a variety of public and private institutions active in the maritime industry. All interviews were conducted in confidence: no individual views are identified in the report. (AT)

    The liquefaction of offshore natural gas is a relatively new technology, and years of intensive research and development indicate that it is now feasible. But problems can occur in the phase of merchandising the cryogenic liquid. In this context, the necessary steps start with the intermediate product storage which maybe integrated in the liquefaction platform, or which possibly has to be on an external structure. The product transfer from the platform to the exporting tanker is another problem area. The paper deals with the principle design features of the liquefaction plant's supporting structure (barge, semisubmersible or fixed platform). Special emphasize is given to the technical, the operational and the economic aspects of the product transfer from the offshore liquefaction site to the coastal terminal and these considerations are summarized under the heading merchandising.

    The Russian Shipyard ''Zvyozdochka'' has designed a new container for transportation and storage of solid radioactive wastes. The PST1A-6 container is cylindrical shaped and it can hold seven standard 200-liter (55-gallon) drums. The steel wall thickness is 6 mm, which is much greater than standard U.S. containers. These containers are fully certified to the Russian GOST requirements, which are basically identical to U.S. and IAEA standards for Type A containers. They can be transported by truck, rail, barge, ship, or aircraft and they can be stacked in 6 layers in storage facilities. The first user of the PST1A-6 containers is the Northern Fleet of the Russian Navy, under a program sponsored jointly by the U.S. DoD and DOE. This paper will describe the container design and show how the first 400 containers were fabricated and certified.

    Full Text Available Accurate and reliable information is needed to support decision-making processes. Due to the large number of participants typically involved in supply chain operations, organizations often find that it is difficult to effectively share information within a supply chain; hence, this research examined ways to improve information sharing within supply chain operations for one marine transportation services organization. An action research, case study approach used the Design for Six Sigma (DFSS methodology to design an information technology solution that effectively communicates information between the layers within the supply chain regarding the movement of materials via inland tank barges. The comparative analysis of verification and baseline measurements conducted suggests this project was successful because the new process fulfilled the needs of the work environment for which it was designed. For the organization that participated in this research, the successful adoption of the new approach for information sharing improved communication and decision making within their supply chain.

  20. Offshore concrete structures

    Lamas Pardo, M.; Carral Couce, L. M.

    2011-01-01

    In the offshore industry there are two possible materials for the construction of the hull of a structure; the steel and concrete, with the first one widely used until now, as in the rest of the shiphuidling industry of merchant ships, warships, etc. Materials such as aluminum, GRP or timber areused in small units with lengths lower than 100 m, and in less adverse conditions than in the offshore industry. Nevertheless, some ships/barges have been built of concrete in the past, but have been rather isolated cases which have not changed the practice in the industry. In the First and Second World War were built by the scarcity of materials, while the series of barges by Alfred A. Yee was a rare exception. Other units were also made in concrete, but almost anecdotal. Still, the behaviour of these concrete structures, especially in terms of maintenance, has been excellent. Therefore, the fact that the concrete has not had an adequate reception so far in shipbuilding, does not mean that in will not be the material best suited for the offshore industry in the future. The extra displacement and associated fuel costs in concrete ships have been found prohibitive in the past. But the loss of mobility of a concrete hull in relation to a steel hull can be perfectly offset by the advantages offered by the concrete, as the shipping and offshore industry have very different priorities. One of the main differences in these priorities is in terms of maintenance and resistance to fatigue, precisely where the concrete performs better. ships can easily be dry docked for maintenance and repair, while in the offshore platforms these works have to be done in situ so maintenance and fatigue are crucial to them. Besides these, the concrete has other advantages according to findings of several studies. And although they are interested in the conclusions that the makes as they came from people in the concrete industry, the fact that in recent years concrete offshore unit shave been built

    2000-01-01

    The Louisiana Oil Spill Coordinator's Office (LOSCO) was established to improve oil spill response, spill prevention and coordination. Louisiana is challenged with having the highest exposure of oil spills because a large portion of its economy is based on oil and gas exploration and production. LOSCO will find ways to minimize the risk of unauthorized oil spills and will address damage assessment and restoration efforts. The aging oil and gas infrastructure in Louisiana has also been recognized as a potential major source for oil spills. LOSCO locates potential spill locations and assesses the risks associated with the sites, some of which are 100 years old. LOSCO also initiated the following two programs: (1) the Abandoned Barge Program initiated in 1993 to remove abandoned barges that pose a high risk for oil discharge, and (2) the Abandoned Non-Hazardous Oil Waste (NOW) Pit and Facility Program initiated in 1992 to locate and remove structures, pits and wells that pose a risk for oil spills. About 25,000 facilities, pits, sumps and reservoirs have been inventoried and evaluated to determine if they pose a risk to human health or the environment. The Louisiana Oil Spill Prevention and Response Act (OSPRA) of 1991 allocates up to $2 million per year for the abatement of oil spills from abandoned facilities in Louisiana. The state legislature has also created the Applied and Educational Oil Spill Research and Development Program (OSRADP) to fund oil spill research. Since 1993, OSRADP has granted 68 awards in support of 42 projects, many of which focused on recovery and cleanup methods including in-situ burning, fate and effect of oil in Louisiana environments, bioremediation, phytoremediation, composting, chemical cleaners, dispersants, sorbents, and solidifiers. 3 refs., 1 tab

    This volume presents the results of the first phase of the Station Keeping Subsystem (SKSS) design study for 40 MW/sub e/ capacity Modular Experiment OTEC Platforms. The objectives of the study were: (1) establishment of basic design requirements; (2) verification of technical feasibility of SKSS designs; (3) identification of merits and demerits; (4) estimates of sizes for major components; (5) estimates of life cycle costs; (6) deployment scenarios and time/cost/risk assessments; (7) maintenance/repair and replacement scenarios; (8) identifications of interface with other OTEC subsystems; (9) recommendations for and major problems in preliminary design; and (10) applicability of concepts to commercial plant SKSS designs. A brief site suitability study was performed with the objective of determining the best possible location at the Punta Tuna (Puerto Rico) site from the standpoint of anchoring. This involved studying the vicinity of the initial location in relation to the prevailing bottom slopes and distances from shore. All subsequent studies were performed for the final selected site. The two baseline OTEC platforms were the APL BARGE and the G and C SPAR. The results of the study are presented in detail. The overall objective of developing two conceptual designs for each of the two baseline OTEC platforms has been accomplished. Specifically: (1) a methodology was developed for conceptual designs and followed to the extent possible. At this stage, a full reliability/performance/optimization analysis based on a probabilistic approach was not used due to the numerous SKSS candidates to be evaluated. A deterministic approach was used. (2) For both of the two baseline platforms, the APL BARGE and the G and C SPAR, all possible SKSS candidate concepts were considered and matrices of SKSS concepts were developed.

    1999-05-01

    Different methods to separate quark jets from gluon jets have been investigated and tested on data from the DELPHI experiment. A test sample of gluon jets was selected from bb-barg threejet events where the two b-jets had been identified using a lifetime tag and quark jet sample was obtained from qq-barγ events where the photon was required to have a high energy and to be well separated from the two jets. Three types of tests were made. Firstly, the jet energy, which is the variable most frequently used for quark/gluon jet separation, was compared with methods based of the differences in the fragmentation of quark and gluon jets. It was found that the fragmentation based classification provides significantly better identification than the jet energy only in events where the jets all have approximately the same energy. In Monte Carlo generated symmetric e + e - → qq-barg threejet events, where the jet energy does not provide any identification at all, the gluon jet was correctly assigned in 58 % of the events. More important, however, is that the identification has been divided into two independent parts, the energy part and the fragmentation part. Secondly, two different sets of fragmentation sensitive variables were tested. It was found that a slightly better identification could be achieved using information from all the particles of the jet rather than using only the leading ones. Thirdly, three types of statistical discrimination methods were compared: a cut on a single fragmentation variable; a cut on the Fisher statistical discriminant calculated from one set of variables; a cut on the output from an Artificial Neural Networks (ANN) trained on different sets of variables. The three types of classifiers gave about the same performance and one conclusion from this study was that the use of ANNs or Fisher statistical discrimination do not seem to improve the results significantly in quark/gluon jet separation on a jet to jet basis

    Supply of fresh water on sustainable basis to all inhabitants is the national responsibility. As a part of national programme to improve quality of life in our society, Desalination Division, BARC has undertaken a project on construction of barge mounted mobile desalination unit of capacity 50 m 3 /d under the domain of health care. The plant is capable of producing safe drinking water at any site and condition where potable water is limited from water sources as lakes and dams, spring, river, bores, estuaries, and open sea. The unit is also capable of purifying nuclear, biological and chemical contaminated water source namely arsenic, fluoride and nitrate. However, the main objective of this prototype mobile unit is to derive potable water from sea water. The barge mounted desalination plant could be useful to the people on shore, in areas like Rann of Kutch or coastal areas which had been affected by natural calamities like floods or severe drought; in small islands like Lakshadeep and Andaman and Nicobar. This type of mobile unit could also be useful for constructional purposes of plants located adjoining to the shore. The plant encompasses state of art reverse osmosis (RO) technology with membrane based ultrafiltration (UF) pretreatment system along with built-in back wash provision and remineralisation. The system is designed for heavy duty tasks in order to withstand frequent relocation from site to site and in skid patterns for portable transportation via road upon requirement. The conceptual design of the plant is over. The design and constructional aspects of the mobile plant are elaborated in this paper. (author)

  6. Seismic data collection from water gun and industrial background sources in the Chicago Sanitary and Ship Canal area, Illinois, 2011

    The water gun is a tool adapted from deep marine geophysical surveys that is being evaluated for use as an acoustic fish deterrent to control the movement of invasive marine species. The water gun creates a seismic signal by using a compressed air discharge to move a piston rapidly within the water, resulting in an implosion. This energy pulse may be able to modify fish behavior or destroy marine life, such as the Asian carp, at some distance. The effects of this energy pulse on structures in the Chicago Sanitary and Ship Canal (CSSC), such as canal walls, shore lines, and lock structures, are not known. The potential effects of the use of a water gun on structures was identified as a concern in the CSSC and was assessed relative to existing background sources during this study. During September 2011, two water guns with piston sizes of 80 and 343 cubic inches, respectively, were tested in the CSSC at varying pressures and distances from a canal wall consisting of dolomite and dolomite setblock. Seismic data were collected during these water gun firings using geophones on land, in boreholes, and at the canal wall interface. Data were collected at varying depths in the canal water using hydrophones. Seismic data were also collected during the occurrences of barge traffic, railroad traffic located near the electric fish barrier in Lemont, and coal-loading operations at a coal power plant near the electric fish barrier. In general, energy produced by barge and railroad sources was less than energy created by the water gun. Energy levels produced by coal-loading operations at least 200 feet from geophones were approximately four times lower than energy levels measured during water gun operations.

    The prevention of non-indigenous aquatic invasive species spreading into new areas is a goal of many resource managers. New techniques have been developed to survey for species that are difficult to capture with conventional gears that involve the detection of their DNA in water samples (eDNA). This technique is currently used to track the invasion of bigheaded carps (silver carp and bighead carp; Hypophthalmichthys molitrix and H. nobilis) in the Chicago Area Waterway System and Upper Mississippi River. In both systems DNA has been detected from silver carp without the capture of a live fish, which has led to some uncertainty about the source of the DNA. The potential contribution to eDNA by vectors and fomites has not been explored. Because barges move from areas with a high abundance of bigheaded carps to areas monitored for the potential presence of silver carp, we used juvenile silver carp to simulate the barge transport of dead bigheaded carp carcasses, slime residue, and predator feces to determine the potential of these sources to supply DNA to uninhabited waters where it could be detected and misinterpreted as indicative of the presence of live bigheaded carp. Our results indicate that all three vectors are feasible sources of detectable eDNA for at least one month after their deposition. This suggests that current monitoring programs must consider alternative vectors of DNA in the environment and consider alternative strategies to minimize the detection of DNA not directly released from live bigheaded carps.

  8. Economic Models for Inland Navigation in the Context of Climate Change

    2011-01-01

    The inland navigation market of North-Western Europe faces potential problems due to climate change. Different measures may be taken by governments, carriers, and customers to cope with the negative effects of climate change. The effects of climate change on the inland navigation market may also be different for regions with different demand for transport by inland navigation. The research carried out in this dissertation can be seen as an investigation into adaptation strategies and the interaction-effects of imbalance and climate change on the inland navigation market. This gives rise to the following two main research questions for this dissertation: (1) What is the optimal barge-size adjustment for barge operators to cope with climate change, and what are the implications of climate change for investments in inland waterway infrastructure by the public sector?; (2) What is the impact of climate change on freight prices in the inland navigation market in the presence of direction dependent freight imbalances? There is still a gap in the scientific literature on the transport economic aspects of inland navigation in general. This dissertation contributes to this literature by approaching the field in a climate change context. In addition, the incorporation of imperfect information to the backhaul literature can be seen as a contribution to the economic theory. We show that imbalance leads to different impacts of climate change in different regions (even though the climate change may be the same for these regions). As a contribution to decision making, the adaptation strategies that are evaluated from a welfare economic perspective can be mentioned. Both private decision making (choice of barge size) and public decision making (choice of amount to invest in infrastructure) are supported, by providing the optimal values to be chosen for the instruments available. By taking the imbalance issue into account, this study gives insights into how to achieve a fair

    Full Text Available Dans la conjoncture actuelle, la situation de l'offshore pétrolier semble plus prometteuse que par un passé récent car, au moins, soixante pays ont des ressources existantes ou possibles. Depuis 1975, la technique pétrolière a continué à progresser mais, surtout dans le domaine du développement des champs. Pour les plates-formes de production en acier, celles des champs de Cognac, Hondo, Ninian et Maureen se distinguent des autres, soit par leur architecture, soit par leurs dimensions. Les plates-formes en béton sont installées, pour la plupart, en mer du Nord, celle du champ de Ninian dépassant toutes les autres en dimensions. Une exception, le Brésil, avec trois plates-formes en eau peu profonde. Pour les champs marginaux, ou pour préciser les caractéristiques d'un gisement découvert, la mise en production se fait à partir de têtes de puits sous-marines, d'un manifold et de liaisons à un ouvrage flottant (plate-forme semi-submersible, tanker. Peu de modifications ont été apportées aux plates-formes semi-submersibles. Seule la plate-forme Sedco 709 est différente des autres car elle est positionnée dynamiquement. Les plus importantes opérations de levage en mer sont assurées par des grues de très forte capacité. La conception des postes de chargement reste le domaine de quelques sociétés. Quant à la pose de pipelines et de conduites, elle a évolué par l'apparition d'ouvrages tels que les barges Castoro VI de Saipem et Apache de Santa Fe et le navire Flexservice 1.

    Since 1995, the Confederated Tribes of the Colville Reservation (Colville Confederated Tribes) have managed the Chief Joseph Kokanee Enhancement Project as part of the Northwest Power Planning Council (NWPPC) Fish and Wildlife Program. Project objectives have focused on understanding natural production of kokanee (a land-locked sockeye salmon) and other fish stocks in the area above Grand Coulee and Chief Joseph Dams on the Columbia River. A 42-month investigation from 1996 to 1999 determined that from 211,685 to 576,676 fish were entrained annually at Grand Coulee Dam. Analysis of the entrainment data found that 85% of the total entrainment occurred at the dam's third powerplant. These numbers represent a significant loss to the tribal fisheries upstream of the dam. In response to a suggestion by the NWPPC Independent Scientific Review Panel, the scope of work for the Chief Joseph Kokanee Enhancement Project was expanded to include a multiyear pilot test of a strobe light system to help mitigate fish entrainment. This report details the work conducted during the third year of the strobe light study by researchers of the Colville Confederated Tribes in collaboration with the Pacific Northwest National Laboratory. The objective of the study is to determine the efficacy of a prototype strobe light system to elicit a negative phototactic response in kokanee and rainbow trout under field conditions. The prototype system consists of six strobe lights affixed to an aluminum frame suspended 15 m vertically underwater from a barge secured in the center of the entrance to the third powerplant forebay. The lights, controlled by a computer, illuminate a region directly upstream of the barge. The 2003 study period extended from June 16 through August 1. Three light treatments were used: all six lights on for 24 hours, all lights off for 24 hours, and three of six lights cycled on and off every hour for 24 hours. These three treatment conditions were assigned randomly

A test sample of gluon jets was selected from bb-barg threejet events where the two b-jets had been identified using a lifetime tag and quark jet sample was obtained from qq-bar{gamma} events where the photon was required to have a high energy and to be well separated from the two jets. Three types of tests were made. Firstly, the jet energy, which is the variable most frequently used for quark/gluon jet separation, was compared with methods based of the differences in the fragmentation of quark and gluon jets. It was found that the fragmentation based classification provides significantly better identification than the jet energy only in events where the jets all have approximately the same energy. In Monte Carlo generated symmetric e{sup +}e{sup -} {yields} qq-barg threejet events, where the jet energy does not provide any identification at all, the gluon jet was correctly assigned in 58 % of the events. More important, however, is that the identification has been divided into two independent parts, the energy part and the fragmentation part. Secondly, two different sets of fragmentation sensitive variables were tested. It was found that a slightly better identification could be achieved using information from all the particles of the jet rather than using only the leading ones. Thirdly, three types of statistical discrimination methods were compared: a cut on a single fragmentation variable; a cut on the Fisher statistical discriminant calculated from one set of variables; a cut on the output from an Artificial Neural Networks (ANN) trained on different sets of variables. The three types of classifiers gave about the same performance and one conclusion from this study was that the use of ANNs or Fisher statistical discrimination do not seem to improve the results significantly in quark/gluon jet separation on a jet to jet basis 45 refs

    Radiation has existed everywhere in the environment since the Earth's formation - in rocks, soil, water, and plants. The mining and processing of naturally occurring radioactive materials for use in medicine, power generation, consumer products, and industry inevitably generate emissions and waste. Radiological measuring devices have been used by industry for years to measure for radiation in undesired locations or simply identify radioactive materials. Since the terrorist attacks on the United States on 9-11-01 these radiation measuring devices have proliferated in many places in our nation's commerce system. DOE, TVA, the Army Corps and ORNL collaborated to test the usefulness of these devices in our nation's waterway system on this project. The purpose of the Watts Bar Dam ORNL Trusted Corridors project was to investigate the security, safety and enforcement needs of local, state and federal government entities for state-of-the-art sensor monitoring in regards to illegal cargo including utilization of the existing infrastructure. TVA's inland waterways lock system is a recognized and accepted infrastructure by the commercial carrier industry. Safety Monitoring activities included tow boat operators, commercial barges and vessels, recreational watercraft and their cargo, identification of unsafe vessels and carriers, and, monitoring of domestic and foreign commercial vessels and cargo identification. Safety Enforcement activities included cargo safety, tracking, identification of hazardous materials, waterway safety regulations, and hazardous materials regulations. Homeland Security and Law Enforcement Applications included Radiological Dispersive Devices (RDD) identification, identification of unsafe or illicit transport of hazardous materials including chemicals and radiological materials, and screening for shipments of illicit drugs. In the Fall of 2005 the SensorNet funding for the project expired. After several unsuccessful attempts to find a Federal sponsor

    Highlights: • Externalities are examined for pipelines, truck, rail, and barge. • Safety impact factors include incidences of injuries, illnesses, and fatalities. • Environmental impact factors include CO 2 eq emissions and air pollution disease burden. • Externalities are estimated for constructing and operating a large domestic pipeline. • A large pipeline has lower cumulative impacts than other modes within ten years. - Abstract: The construction of pipelines along high-throughput fuel corridors can alleviate demand for rail, barge, and truck transportation. Pipelines have a very different externality profile than other freight transportation modes due to differences in construction, operation, and maintenance requirements; labor, energy, and material input intensity; location and profile of emissions from operations; and frequency and magnitude of environmental and safety incidents. Therefore, public policy makers have a strong justification to influence the economic viability of pipelines. We use data from prior literature and U.S. government statistics to estimate environmental, public health, and safety characterization factors for pipelines and other modes. In 2008, two pipeline companies proposed the construction of an ethanol pipeline from the Midwest to Northeast United States. This proposed project informs our case study of a 2735-km $3.5 billion pipeline (2009 USD), for which we evaluate potential long-term societal impacts including life-cycle costs, greenhouse gas emissions, employment, injuries, fatalities, and public health impacts. Although it may take decades to break even economically, and would result in lower cumulative employment, such a pipeline would likely have fewer safety incidents, pollution emissions, and health damages than the alternative multimodal system in less than ten years; these results stand even if comparing future cleaner ground transport modes to a pipeline that utilizes electricity produced from coal

    The 2005 fish collection season at Lower Granite Dam (LGR) was characterized by average water temperatures, below average flows, above average spill, low levels of debris and the record number of smolts collected compared to the previous five years. With the continued release of unclipped supplementation chinook and steelhead above LGR, we cannot accurately distinguish wild chinook, steelhead, and sockeye/kokanee in the sample. For the purposes of this report we will designate fish as clipped and unclipped. This season a total of 13,030,967 juvenile salmonids were collected at LGR. Of these, 12,099,019 were transported to release sites below Bonneville Dam, 12,032,623 by barge and 66,396 by truck. An additional 898,235 fish were bypassed to the river due to over-capacity of the raceways, barges or trucks and for research purposes. This was the first season of summer spill at LGR. Spill was initiated at 12:01am June 20 as directed by the ruling set forth by Judge James Redden of the United States District Court (Order CV 01-640-RE). In addition, the Lower Granite project also conducted a summer spill test alternating spill and spill patterns between spill to the gas cap without the removable spillway weir (RSW) and spill with up to 20 kcfs utilizing the RSW. Because of the forecast low flow this year, most hatchery reared subyearling fall chinook were released up to three weeks early. With the unexpected high flows in late May and early June, more than 90% of the subyearling chinook were collected prior to the initiation of the court ordered summer spill program. Collection number fluctuations reflect river flow and project operations for any given year. For example, low flow years (2001, 2004 and 2005) result in higher collection numbers. Court ordered spill throughout the summer migration will directly affect collection of fall subyearling chinook collection numbers. The editors of this report urge the reader to use caution when comparing fish collection numbers

    The role that fatigue due to sleep deprivation and the resulting impairment of judgment may have played on the striking of a small tanker and an oil barge by a bulk carrier in Hamilton (Ontario) harbour, were described. The pilot guiding the bulk carrier to its berth had been deprived of sleep for 22 hours prior to boarding the vessel, and it was suspected that sleepiness may have played a role in this occurrence. Research into circadian rhythms and sleep confirm these suspicions. Performance of cognitive and vigilance tasks have been shown to be particularly impaired. There is also increased propensity for risk-taking by fatigued persons. It has been shown that cumulative sleep loss and circadian disruption can lead to decreased waking alertness, impaired performance, and worsened mood. In expressing the Transportation Safety Board`s concern about the vulnerability of individuals in safety-sensitive positions (such as pilots on the Great Lakes) to significant errors in judgment when fatigued, the Board recommended a policy and procedures for allocating pilotage assignments in such a way as to ensure that pilots receive sufficient rest to minimize the adverse effects of fatigue on performance.

    The economic success of an Ocean Thermal Energy Conversion (OTEC) system is highly dependent on a platform which provides adequate support for the power system, accommodates reliably the cold water pipe, and is most cost effective. The results of a study conducted for the Department of Energy to assess six generic types of platforms to determine the most satisfactory platform for severl potential sites are presented. The six platform configurations are ship, circular barge, semi-submersible, Tuned Sphere, submersible, and spar. These represent directional and symmetric types of platforms which operate on the surface, at the interface, and submerged. The five sites for this study were primarily New Orleans, Keahole Point (Hawaii), Brazil, and secondarily Key West and Puerto Rico. Electrical transmission of energy by submarine cable is the planned form of energy transmission for all sites except Brazil, where chemical conversion is to be the method of transmission. This study is devoted to the platform (or ocean systems) of the OTEC plant which is chiefly comprised of the hull and structure, the seawater system, the position control system, and miscellaneous support/assembly systems. The principal elements in the work breakdown structure for the commercial plants are presented. The assessment of the six platform configurations was conducted utilizing a baseline plan (100-MW(e) (Net)) and site (New Orleans) with variations from the baseline to cover the range of interested platforms and sites.

    1983-01-01

    Alternatives for disposal of decontaminated high-level waste salt at Savannah River were reviewed to estimate costs and potential environmental impact for several processes. In this review, the reference process utilizing intermediate-depth burial of salt-concrete (saltcrete) monoliths was compared with alternatives including land application of the decontaminated salt as fertilizer for SRP pine stands, ocean disposal with and without containment, and terminal storage as saltcake in existing SRP waste tanks. Discounted total costs for the reference process and its modifications were in the same range as those for most of the alternative processes; uncontained ocean disposal with truck transport to Savannah River barges and storage as saltcake in SRP tanks had lower costs, but presented other difficulties. Environmental impacts could generally be maintained within acceptable limits for all processes except retention of saltcake in waste tanks, which could result in chemical contamination of surrounding areas on tank collapse. Land application would require additional salt decontamination to meet radioactive waste disposal standards, and ocean disposal without containment is not permitted in existing US practice. The reference process was judged to be the only salt disposal option studied which would meet all current requirements at an acceptable cost

    Bioaccessible U, Th, Pb and the 238 U decay products 214 Pb and 210 Pb have been determined, using a modified Unified BARGE Method (UBM), in waste solids and soils from an abandoned uranium mine in South West England, UK. Maximum aqua regia extractable concentrations for U, Th and Pb were 16,200, 3.8 and 4750 μg g -1 , respectively. 238 U had highest activity concentrations near the mine shaft, where the decay products 214 Pb and 210 Pb had values of 235 and 180 Bq g -1 , respectively. UBM extractions gave mean gastro-intestinal bioaccessibility factors (BAFs) for U and Pb in the waste solids of 0.05 and 0.03, respectively, whereas those for the soils were significantly higher at 0.24 and 0.17. The mean BAFs for the transient radionuclides, 214 Pb and 210 Pb, were similar to those for stable Pb implying that the stable and radioactive Pb isotopes were attached to similar sites on the particles. The doses arising from the ingestion of particulate 210 Pb due to soil pica behaviour were in the range 0.2-65 and 17 years), respectively. The results suggest that the health risk posed by abandoned uranium mines, with waste rock and tailings, throughout the world should take account of the dose due to both bioaccessible radionuclides, as well as their stable counterparts.

    The 2000 fish collection season at Lower Granite was characterized by lower than average spring flows and spill, low levels of debris, cool water temperatures, increased unclipped yearling and subyearling chinook smolts, and 8,300,546 smolts collected and transported compared to 5,882,872 in 1999. With the continued release of unclipped supplementation chinook and steelhead above Lower Granite Dam, we can no longer accurately distinguish wild chinook, steelhead, and sockeye/kokanee in the sample. Although some table titles in this report still show ''wild'' column headings, the numbers in these columns for 1999 and 2000 include wild and unclipped hatchery origin smolts. The increases over previous years reflect the increased supplementation. A total of 8,300,546 juvenile salmonids were collected at Lower Granite Dam. Of these, 187,862 fish were bypassed back to the river and 7,950,648 were transported to release sites below Bonneville Dam, 7,778,853 by barge and 171,795 by truck. A total of 151,344 salmonids were examined in daily samples. Nine research projects conducted by four agencies impacted a total of 1,361,006 smolts (16.4% of the total collection)

    2016-03-01

    Full Text Available Unconventionally-produced crude oils, i.e., Bakken oil and bitumen diluted for transport and known as dilbit, have become prominent components of the North American petroleum industry. Spills of these oils have occurred during transport from production areas to refineries via pipeline, rail, and barge. Some of their physical and chemical properties are distinct and present new challenges in mitigating spill impacts on people and the environment. This paper describes the adaptation of a qualitative risk assessment process to improve spill preparedness and response decisions for these oils when transported in an estuarine area. The application of this collaborative, interdisciplinary process drew upon a literature review, the local knowledge and experience of a broad set of decision makers, practitioners, and technical experts who developed consensus-based recommendations aimed at improving response to spills of these oils. Two emphasized components of this consensus ecological risk assessment (CERA concerned risks: (1 to human health and safety and (2 from spilled oil and the associated response actions on endangered species. Participants in the process defined levels of concern associated with Bakken and dilbit oils relative to a set of response actions in freshwater, brackish and saltwater habitats and on resources at risk.

    In order to explore marine natural resources using remote robotic sensor or to enable rapid information exchange between ROV (remotely operated vehicles), AUV (autonomous underwater vehicle), divers, and ships, ultrasonic underwater communication systems are used. However, if the communication system is applied to rich living creature marine environment such as shallow sea, it suffers from generated Impulsive Noise so-called Shrimp Noise, which is randomly generated in time domain and seriously degrades communication performance in underwater acoustic network. With the purpose of supporting high performance underwater communication, a robust digital communication method for Impulsive Noise environments is necessary. In this paper, we propose OFDM ultrasonic communication system with diversity receiver. The main feature of the receiver is a newly proposed Frequency Domain Diversity Combined Impulsive Noise Canceller. The OFDM receiver utilizes 20-28 KHz ultrasonic channel and subcarrier spacing of 46.875 Hz (MODE3) and 93.750 Hz (MODE2) OFDM modulations. In addition, the paper shows Impulsive Noise distribution data measured at a fishing port in Okinawa and at a barge in Shizuoka prefectures and then proposed diversity OFDM transceivers architecture and experimental results are described. By the proposed Impulsive Noise Canceller, frame bit error rate has been decreased by 20-30%.

    Technological advancements in the Glosten PelaStar floating wind turbine system have led to projected cost of energy (COE) reductions from today’s best-in-class offshore wind systems. The PelaStar system is projected to deliver a COE that is 35% lower than that delivered by the current offshore wind plants. Several technology developments have been achieved that directly target significant cost of energy reductions. These include: Application of state-of-the-art steel construction materials and methods, including fatigue-resistant welding techniques and technologies, to reduce hull steel weight; Advancements in synthetic fiber tendon design for the mooring system, which are made possible by laboratory analysis of full-scale sub-rope specimens; Investigations into selected anchor technologies to improve anchor installation methods; Refinement of the installation method, specifically through development of the PelaStar Support Barge design. Together, these technology developments drive down the capital cost and operating cost of offshore wind plants and enable access to superb wind resources in deep water locations. These technology developments also reduce the uncertainty of the PelaStar system costs, which increases confidence in the projected COE reductions.

    The design concept of a 300 MWt inherently safe integral reactor(ISIR) for the propulsion of extra large and superhigh speed container ship was developed in this report. The scope and contents of this report are as follows : 1. The state of the art of the technology for ship-mounted reactor 2. Design requirements for ISIR 3. Fuel and core design 4. Conceptual design of fluid system 5. Conceptual design of reactor vessel assembly and primary components 6. Performance analyses and safety analyses. Installation of two ISIRs with total thermal power of 600MWt and efficiency of 21% is capable of generating shaft power of 126,000kW which is sufficient to power a container ship of 8,000TEU with 30knot cruise speed. Larger and speedier ship can be considered by installing 4 ISIRs. Even though the ISIR was developed for ship propulsion, it can be used also for a multi-purpose nuclear power plant for electricity generation, local heating, or seawater desalination by mounting on a movable floating barge.

    This study was implemented to examine and characterize the actual environmental impacts of three fuel ethanol plants constructed under the US Department of Energy, Office of Alcohol Fuels Loan Guarantee Program, and to compare actual impacts with those predicted about six years ago in environmental assessments (EAs) prepared for these facilities. The objective of the program, established under the Energy Security Act of 1980, was to conserve petroleum resources by promoting the use of fuel ethanol in motor vehicles. The plants were designed to produce fuel-grade ethanol for blending with gasoline and reflect differentfeedstocks, processes, fuel sources, and site locations. Although two of the facilities as constructed differed substantially from those assessed previously, actual environmental impacts generally occurred in the areas predicted by the EAs. Major impacts not anticipated include odor from air emissions, effects of wastewater discharge on operation of a municipal sewage treatment plant, possible classification of treated wastewater from a molasses-based process as a nuisance, and habitat losses from both vegetation removal and unforeseen construction of barge terminals. In all cases, impacts were judged to be not significantn the final outcome, either because plant management (or other involved parties) took corrective action or because the resources affected in these particular cases were not important. Mitigation measures reliedon in the EAs to limit adverse impacts to insignificant levels were implemented and were required by permit condition, law, or regulation. Future follow-up studies would benefit from the availability of ambientmonitoring data to more thoroughly characterize actual impacts

    1993-01-01

    The Office of Civilian Radioactive Waste Management has been working since the mid-1980s to develop a cask fleet, which will include legal weight truck and rail/barge casks for the transport of spent nuclear fuel (SNF) from reactors to Civilian Radioactive Waste Management System SNF receiving sites. The cask designs resulting from this effort have been identified as Initiative I casks. In order to maximize payloads, advanced technologies have been incorporated in the Initiative I cask designs, and some design margins have been reduced. Due to the wide range of the characteristics (age/burnup) of the spent fuel assemblies to be transported in the Initiative I casks, it has become apparent that a significant portion of the shipments of the Initiative I casks could not be loaded to their design capacity. Application of a more conventional cask design philosophy might result in new generation casks that would be easier to license, have more operational flexibility as to the range of age/burnup fuel that could be transported at full load, and be easier to fabricate. In general, these casks would have a lower capacity than the currently proposed Initiative I casks, thereby increasing the transportation impacts and the transportation costs

  12. Geologic and societal factors affecting the international oceanic transport of aggregate

    Langer, W.H.

    1995-01-01

    Crushed stone and sand and gravel are the two main sources of natural aggregate, and together comprise approximately half the volume and tonnage of mined material in the United States. Natural aggregate is a bulky, heavy material without special or unique properties, and it is commonly used near its source of production to minimize haulage cost. However, remoteness is no longer an absolute disqualifier for the production of aggregate. Today interstate aggregate routinely is shipped hundreds of kilometers by rail and barge. In addition, during 1992, the United States imported 1,317,000 metric tons of aggregate from Canada and 1,531,000 metric tons from Mexico. A number of ports on the Atlantic Coast and Gulf Coast of the United States receive imports of crushed stone from foreign sources for transport to various parts of the eastern United States. These areas either lack adequate supplies of aggregate or are augmenting their supplies because they have difficulties meeting current demand. These difficulties may include poor stone quality, environmental permitting problems, or transportation. Certain societal and geologic conditions of New York City and Philadelphia along the Atlantic Coast, and Tampa and New Orleans along the Gulf Coast, are discussed to demonstrate the different combinations of issues that contribute to the economic viability of importing crushed stone. ?? 1995 Oxford University Press.

    Platform construction GTS (Gathering Testing Sattelite) is offshore construction platform with fix pile structure type/fixed platform functioning to support the mining of petroleum exploitation. After construction fabrication process platform was moved to barges, then shipped to the installation site. Moving process is generally done by pull or push based on construction design determined when planning. But at the time of lifting equipment/cranes available in the work area then the moving process can be done by lifting so that moving activity can be implemented more quickly of work. This analysis moving process of GTS platform in a different way that is generally done to GTS platform types by lifting using problem is construction reinforcement required, so the construction can be moved by lifting with analyzing and checking structure working stress that occurs due to construction moving process by lifting AISC code standard and analysis using the SAP2000 structure analysis program. The analysis result showed that existing condition cannot be moved by lifting because stress ratio is above maximum allowable value that is 0.950 (AISC-ASD89). Overstress occurs on the member 295 and 324 with stress ratio value 0.97 and 0.95 so that it is required structural reinforcement. Box plate aplication at both members so that it produces stress ratio values 0.78 at the member 295 and stress ratio of 0.77 at the member 324. These results indicate that the construction have qualified structural reinforcement for being moved by lifting.

    2016-03-01

    Full Text Available Springing is the resonance phenomenon of a ship hull girder with incoming waves having the same natural frequency of the ship. In this study, a simple and reliable calculation method was developed based on quadratic strip theory using the Timoshenko beam approach as an elastic hull girder. Second-order hydrodynamic forces and Froude–Krylov forces were applied as the external force. To improve the accuracy of the strip method, the variation in the added mass along the ship hull longitudinal direction, so called tip-effect, was considered. The J-factor was also employed to compensate for the effect of three-dimensional fluid motion on the two-node vibration of the ship. Using the developed method, the first- and second-order vertical bending moments of the Flokstra ship were compared. A comparative study was also carried out for a uniform barge ship and a 10,000 TEU container ship with the respective methods including the J-factor and tip-effect.

  16. Methods for estimating costs of transporting spent fuel and defense high-level radioactive waste for the civilian radioactive waste management program

    International Nuclear Information System (INIS)

    Darrough, M.E.; Lilly, M.J.

    1989-01-01

    The US Department of Energy (DOE), through the Office of Civilian Radioactive Waste Management, is planning and developing a transportation program for the shipment of spent fuel and defense high-level waste from current storage locations to the site of the mined geologic repository. In addition to its responsibility for providing a safe transportation system, the DOE will assure that the transportation program will function with the other system components to create an integrated waste management system. In meeting these objectives, the DOE will use private industry to the maximum extent practicable and in a manner that is cost effective. This paper discusses various methodologies used for estimating costs for the national radioactive waste transportation system. Estimating these transportation costs is a complex effort, as the high-level radioactive waste transportation system, itself, will be complex. Spent fuel and high-level waste will be transported from more than 100 nuclear power plants and defense sites across the continental US, using multiple transport modes (truck, rail, and barge/rail) and varying sizes and types of casks. Advance notification to corridor states will be given and scheduling will need to be coordinated with utilities, carriers, state and local officials, and the DOE waste acceptance facilities. Additionally, the waste forms will vary in terms of reactor type, size, weight, age, radioactivity, and temperature

  17. BIBLICAL SYMBOLISM IN THE NOVEL “THE WANDERERS” BY V. Y. SHISHKOV

    Directory of Open Access Journals (Sweden)

    Valentina I. Gabdullina

    2017-06-01

    Full Text Available The article presents the experience of reinterpretation of the novel of V. Y. Shishkov as the phenomenon of “spiritual realism”, from the point of view of identifying the role and functions of biblical symbolism and imagery in its artistic system. Biblical symbolism pervades the narration, manifesting itself both at the level of the semantics of names and imagery, and in a three-part compositional structure of the novel that conveys the author’s idea — the movement of the characters from the darkness of the underworld to the light. Life of the homeless children is depicted by the author as the “dark world”, “antiworld”, which disfigures all the concepts ontologically important for Man. The idea of spiritual commonality is replaced by the thieves brotherhood, the life of street children under the inverted barge turns into a hideous parody of monastic life, the place of the Virgin in this world is given to a prostitute girl Mashka nicknamed May Flower. In the plot of the story the motifs of the Apocalypse (destruction of the old world and of the prodigal son in the heroes’ life stories who undergo transformations take place in parallel. The interpretation of biblical symbols, which saturated Shishkov’s novel “The Wanderers” brings new connotations, still unrevealed in literature studies, that reside in the content of this work.

  18. Studies and research concerning BNFP. Nuclear transportation studies related to use of the Barnwell Nuclear Fuel Plant

    Anderson, R.T.

    1981-11-01

    It will be necessary to transport radioactive material on a routine basis if the Barnwell Nuclear Fuel Plant (BNFP) is to be utilized. This report examines the current and projected status of transport of high-level nuclear material, with particular application directed toward the operation of the BNFP. The current domestic US status is one of comparative inactivity in the movement of utility spent fuel. Pending the successful disposition of fuel cycle options such as either Away-from-Reactor (AFR) storage or reprocessing, spent fuel transport to the BNFP will be dormant through the mid-1980's. If fuel movement is initiated, the primary areas of concern will be the maze of local, state, and federal regulations on routing, the availability of spent fuel casks, and the logistic concerns of fuel loading and unloading capability at the reactor and the BNFP. The report examines the application of overweight truck (OWT) shipments of spent fuel casks patterned on current European practice. Overweight shipments, whether by truck or intermodal movement (rail or barge combined with truck shipment), can have a significant impact on resolving logistics problems. It seems obvious from our studies that OWT casks will be utilized, along with legal weight truck and rail shipment. Water transport was also examined. It appears that this mode will only be used in the event that highway and rail problems are insuperable

  19. Applicability of the Clean Water Act to Indian tribes - may tribes stop or constrain a cleanup?

    International Nuclear Information System (INIS)

    Emge, M.L.

    1993-01-01

    Indian tribes retain their sovereign rights of self-government and self-determination unless it is specifically waived by the tribe or abrogated by the US Congress, through treaty or statute. The Clean Water Act does not specifically abrogate tribal sovereignty. This raises the issue of what would occur if an on-scene coordinator decides that cleanup of tribal lands is necessary to protect the public health and welfare, but the tribe does not want the cleanup activities to proceed? May a tribe impede cleanup efforts? During the cleanup of the barge Nestucca oil spill, this occurred when the Quinault Tribe did not allow the OSC to clean lands that the tribe holds sacred. This issue with the Clean Water Act has not been decided by Congress, nor by the courts. Recently, courts have applied at least three different approaches to determine if a statute of general application, such as the Clean Water Act, applies to Indian tribes. The different tests do not always yield the same result. An on-scene coordinator, when confronted with this scenario, might handle the situation in several different ways, or perhaps move to prevent such an occurrence. The different approaches used by the courts can be taken together to gain a sense of whether the Clean Water Act may preempt tribal sovereignty

    Port Island is an artificial island made up of sand and soil from Mount Takakura in the Rokko mountain range of Japan. The materials were carried to the coast of Suma a distance of 7.1 kilometers by a specially devised overhead conveyor belt from Kobe City. Work on the island still continues today. On the average, 7000 dump trucks a day have been mobilized at the conveyor belt facilities. The materials are transported from the coast by pusher-barges that have specially designed bottoms that open and dump the building materials on the sea bed. The island is linked to Kobe City by a huge bridge. It is serviced by a fully automatic monorail. A new city was also created at the site where the sand and soil were removed. A joint study with the Kobe City authority and local experts under the support and cooperation of the United Nations Fund for Population Activities (UNFPA) was initiated. The administrative structure and financing required of a project of this magnitude need to be examined. The organizational structure and management style of local governments undertaking the project were non-bureaucratic, efficient and flexible. Kobe City authorities secured the necessary funds by issuing the German mark bond. A research on Kobe City and the redistribution of population is planned. More living space and better living conditions resulted from the project.

  1. Environmental assessment for DOE permission for the off-loading and transportation of commercial low-level radioactive waste across the Savannah River Site

    International Nuclear Information System (INIS)

    1997-10-01

    The Department of Energy (DOE) prepared this Environmental Assessment (EA) to assess the potential environmental impacts associated with DOE allowing Chem-Nuclear Systems, L.L.C. (CNS) to off-load and transport low-level radioactive waste (LLW) packages across the Savannah River Site (SRS), located near Aiken, South Carolina, to the nearby CNS facility. The proposed action entails DOE granting permission to CNS to use SRS for landing shipping barges at the existing SRS boat ramp and off-loading trailered LLW packages for transportation across SRS to the CNS facility. Project activities would include modification of the SRS boat ramp on the Savannah River, as needed for off-loading activities, and construction of a bridge across Lower Three Runs. The proposed action also encompasses any similar future off-loading and transportation activities for LLW en route to the CNS facility. The National Environmental Policy Act requires the assessment of environmental consequences of Federal actions that may affect the quality of the human environment. Based on the potential for impacts described herein, DOE will either publish a Finding of No Significant Impact or prepare an Environmental Impact Statement (EIS)

    1979-04-01

    The successful performance of the CWP is of crucial importance to the overall OTEC system; the pipe itself is considered the most critical part of the entire operation. Because of the importance the CWP, a project for the analysis and design of CWP's was begun in the fall of 1978. The goals of this project were to study a variety of concepts for delivering cold water to an OTEC plant, to analyze and rank these concepts based on their relative cost and risk, and to develop preliminary design for those concepts which seemed most promising. Two representative platforms and sites were chosen: a spar buoy of a Gibbs and Cox design to be moored at a site off Punta Tuna, Puerto Rico, and a barge designed by APL/Johns Hopkins University, grazing about a site approximately 200 miles east of the coast of Brazil. The approach was to concentrate on the most promising concepts and on those which were either of general interest or espoused by others (e.g., steel and concrete concepts). Much of the overall attention, therefore, focused on analyzing rigid and compliant wall design, while stockade (except for the special case of the FRP stockade) and bottom-mounted concepts received less attention. A total of 67 CWP concepts were initially generated and subjected to a screening process. Of these, 16 were carried through design analysis, costing, and ranking. Study results are presented in detail. (WHK)

    Aspecially designed netwas used to study fish entrainment and injury through towboat propellers in 13 pools of the Upper Mississippi and Illinois rivers. The net was attached to the stern of a 48.8-m-long towboat with twin propellers (in Kort propulsion nozzles), and sampling typically took place while the towboat pushed 15 loaded barges upstream at a time. In total, 254 entrainment samples over 894 km of the 13 study pools were collected. The sampling efforts produced 16,005 fish representing 15 families and at least 44 species; fish ranged in total length from 3 to 123 cm, but only 12.5-cm or longer fish were analyzed because smaller fish could escape through the mesh of the trawl. Clupeidae (68% of total catch) and Sciaenidae (21%) were the dominant families. We detected no effects of towboat operation variables (speed and engine [i.e., propeller] revolutions per minute [RPM]) on entrainment rate (i.e., fish/km), but entrainment rate showed a wedge-shaped distribution relative to hydraulic and geomorphic characteristics of the channel. Entrainment rate was low (30 fish/km). Although total entrainment rate was not related to engine RPM, the probability of being struck by a propeller increased with fish length and engine RPM. Limits on engine RPM in narrow, shallow, and sluggish reaches could reduce entrainment impact, particularly for large-bodied fish. ?? American Fisheries Society 2011.

    1996-01-01

    An overview of technological innovations in spill response by Alyeska Pipeline Service Company/SERVS (ship escort response vessel system), was presented. The company has developed a number of spill response techniques which have needed new strategies and modified equipment for fulfillment of the Prince William Sound Tanker Oil Discharge Prevention and Contingency Plan. One of the strategies was the training of personnel to be ready to deploy massive quantities of equipment on short notice to potential spill sites over an 11,000 square mile water body with more than 3,200 miles of wilderness shoreline. Specific response equipment and decision-making tools have been developed in direct support of large scale programs. Along with oil slick tracking buoys and mini barges, SERVS has developed high capacity skimmers with recovery capacities approaching 2,000 to 3,000 barrels of liquid per hour and strategy boom-towing vessels which divert oil into a long U shaped containment boom. SERVS fishing vessel program, hatchery protection and remote response center equipment program, and wildlife treatment facilities were also described. 10 refs., 13 figs

    2001-06-01

    Western Pulp Inc. acquired a used Chip Thickness Screening and conditioning system at reduced cost in April 2000. It purchased the used screen facility from Bowater's closed down Gold River mill. The advantages of a system similar to the Gold River mill are many: improved yield, improved brown stock washing, reduced bleach chemical consumption, increased pulp strength, improvement of the pulp machine performance, and improved overall quality. The author explained the project that involved moving the entire 1100 ton, 5 story building by barge to the Western Pulp Inc. site located at Squamish. Sandwell Engineering performed the detailed design and the construction phase began soon after. Once on location, the newly acquired facility was set into position and integrated with the remainder of the facilities. For the purpose of proper chip flow and pile management, a new chip reclaim and conveyors were installed. The tie-ins and foundations necessitated special attention to design details. Commonwealth Construction was responsible for the completion of the tie-ins, which took place during the mill annual shutdown. The operation of the new screen facility, which began on December 19, 2000, resulted in lower bleaching costs, energy savings, an increase in production (3.5 per cent in February 2001), as well as a lowering in black liquor solids. Based on the cost savings realized to date, it is expected that the payback period will be one year. 1 tab., 11 figs.

    American experience in the ethanol industry is discussed. Archer Daniel Midlands Co. (ADM) is a large agri-processing company that is the largest processor of grains and oilseeds, and processes ca 400,000 bushels of corn per day at its Decateur facility. Waste water and heat from the plant is used to grow vegetables hydroponically, with carbon dioxide from distillation used to speed growing at night. About 40,000 heads of lettuce per day are harvested, with cucumbers and tomatoes grown as premium crops. The plant includes a state-of-the-art fluidized bed power plant that burns high sulfur coal without sulfur emission. Approval has recently been granted by the Environmental Protection Agency to burn used tires, and payback for the process is expected to take 3-4 years. Ethanol is produced by steeping corn and separating germ and starch, with the starch used to make corn sweeteners. As well as ethanol, byproducts include animal feed, hydroponics, oils and margarines. ADM is the largest barging company in the U.S., with 14,000 rail cars, 1,200 dedicated to fuel ethanol. The Clean Air Act will mandate a 2.7% oxygen gasoline, and 10% ethanol additive gives 3.3% oxygen. The high octane rating of ethanol-blend gasoline is a strong selling point, and is a good deal for refiners, especially at octane-poor refineries.

    2005-01-01

    The trends in oil spills around the world over from 1995 to 2004 were examined and analyzed for possible influences on spill volumes and frequencies for incidents of 3 spill size classes. The International Tanker Owners Pollution Federation (ITOPF) has maintained a database since 1974 of all oil spills from tankers, combined carriers and barges. The number of oil spills has decreased significantly in the last 30 years despite a steady increase in maritime oil trade since the 1980s. The recent trends were identified by causes, locations, oil type, and shipping legislation. The causes include ship loading/discharging, bunkering, collisions, groundings, hull failures and fires. The types of oil spilt include bunker, crude, cargo fuel, white product and some unknowns. It was concluded that the decline in oil spills is due to a range of initiatives taken by governments and the shipping industry rather than any one factor. Some notable influences towards reduced number of spills include: the international convention for the prevention of pollution from ships of 1972, as modified by the Protocol of 1978; the international convention for the safety of life at sea of 1974; and the Oil Pollution Act of 1990. Results of investigations into the causes of spills serve the purpose of informing the international process to further prevent and reduce marine oil pollution due to tankers. 7 refs., 5 tabs., 12 figs

    1992-01-01

    Five studies are presented which assess the impacts of global warming on physical, economic, and social systems in Canada. A study on the use of climatic change scenarios to estimate ecoclimatic impacts was carried out. These scenarios may include synthetic scenarios produced from historical data, global climate model (GCM) simulations, and hybrid scenarios. The advantages and drawbacks of various scenarios are discussed along with the criteria for selecting impact assessment models. An examination of water resources in the Great Lakes and the Saskatchewan River subbasin uses case studies of two areas that have experienced wide hydrological variations due to climatic variability in order to determine the impacts of global warming scenarios on net basin supply. Problems of developing regional models are discussed and results of projected changes in net basin supply are presented for GCM-based simulations and hypothetical warming scenarios. A study of the impacts of climate warming on transportation and the regional economy in northern Canada uses stochastic models to provide examples of how Mackenzie River barge traffic will be affected. The economic impacts of the resultant lengthened shipping season are outlined under three scenarios. The implications of climatic change on Ontario agriculture are assessed according to GCM scenarios. Results are presented for crop yields and production as well as land resource suitability. Finally, sociocultural implications of global warming on the Arctic and the Inuit are summarized, with reference to a past warming episode occurring around the year 1000. 45 refs., 4 figs., 3 tabs

  12. Social marketing of condoms: selling protection and changing behavior.

    1991-06-01

    Social marketing of condoms in Zaire began in 1987 and sales rose to 8 million in 1990, a notable change from the previous situation where about half a million condoms were distributed by government health clinics only. Social marketing is the use of for-profit sales and marketing techniques for public health problem.s When the Zaire National AIDS Committee initiated social marketing of condoms, with the assistance of Population Services International, they had the experience of successful Asian programs of the 1970s, and the political sanction resulting from the AIDS threat to back them up. Efforts were made to find just the right product name, "Prudence," logo, package, color and slogan by consumer research. Prudence implies responsible behavior, capturing both the AIDS and STD prevention and the family planning markets. Consumers like the package and associate it with quality, since most condoms sold before in Zaire had no special packaging. Distribution outlets include 7000 retail shops, groceries, pharmacies, hotel, social clubs, 300 bars and even Congo River barges which sex workers frequent. The price was set close to that of a pack of gum for 3, or that of a bottle of beer for a dozen. Promotion is limited by a government ban of advertising in mass media, so point of purchase materials, special offers and promotional items are being used. Prudence condoms are now being marketed in Cameroon and Burundi.

    Were prepared two organoclays aiming at studying their adsorption properties. The clayssed were the Brazilian Bentongel and Argentina Green Lake. The clays were characterized and organoclays. Performed analyzes of X-Ray diffraction, infrared, SEM, thermogravimetry and swelling experiments Foster and adsorption ASTM. The X-ray diffraction indicated collation of lamellar organic cation used. The variations thermogravimetrics were negative and ranged from around 24% in organophilic clays. The results of infrared spectroscopy indicated the presence of bands that show this barge. The form of the particles/agglomerates of clay minerals was verified by SEM before and after organofilization. The values of the measures of swelling were up to 30 mL/g for some solvents. The adsorption test showed good ability of sorption per gram of clay, reaching respectively 10.2g/g and 9.9 g/g for gasoline and ethylbenzene. These high values indicate that the modified clay may have potential use in sectors of environmental toxicity control industrial and separation. (author)

The work was managed by the U.S. Army Corps of Engineers (USACE) Alaska District for the U.S. Department of Energy (DOE) Office of Legacy Management (LM). Due to the short field season and the tight barge schedule, all field work was conducted at the site July 6 through September 12, 2014. Excavation activities occurred between July 16 and August 26, 2014. A temporary field camp was constructed at the site prior to excavation activities to accommodate the workers at the remote, uninhabited location. A total of 785.6 tons of petroleum, oil, and lubricants (POL)-contaminated soil was excavated from four former drill sites associated with test holes installed circa 1960. Diesel was used in the drilling process during test hole installations and resulted in impacts to surface and subsurface soils at four of the five sites (no contamination was identified at Test Hole Able). Historic information is not definitive as to the usage for Test Hole X-1; it may have actually been a dump site and not a drill site. In addition to the contaminated soil, the steel test hole casings were decommissioned and associated debris was removed as part of the remedial effort.

    1986-04-01

    National participation in nuclear power projects was a star subject in the seventies in dealings between supplying and receiving countries; around it international gatherings like ICONTT conferences, IAEA meetings, and others were almost institutionalized. The fact that many of those dealings, which were prosecuted for extended periods, are not being materialized into actual projects (suffice it to mention those of Mexico, Pakistan, Turkey, Egypt, China, etc.) has provided a slow shift of the title role in the international nuclear picture to the apparent main obstacles to that materialization, that is, financial and/or non-proliferation aspects. But, in fact, a growing, well planned participation by a country's industry, its organizations and its individuals in its nuclear programme is clearly the most important product (other than, obviously, power itself) that can be derived from such a programme. A product from which many other sectors benefit. This paper deals with significant aspects of the national participation effort, among other: existing industrial infrastructure, and its evaluation; technology transfer channels and its implications; situations where national participation may look less easy to implement: turnkey projects, shop-mounted or barge-installed blocks or complete plants, etc.; progressive participation along the project, and with subsequent projects; the role of the utility and the Government. Cases drawn from the experience of the author's company in several countries, and specially the case of Spain, are commented. (author)

    The objective of this study was to assess the contamination level of potentially harmful elements (PHEs) in industrial soils and how this relates to environmental magnetism. Moreover, emphasis was given to the determination of the potential mobile fractions of typically "technogenic" metals. Therefore, magnetic and geochemical parameters were determined in topsoils (0-20 cm) collected around a chemical industry in Sindos Industrial Area, Thessaloniki, Greece. Soil samples were presented significantly enriched in "technogenic" metals such Cd, Pb, and Zn, while cases of severe soil contamination were observed in sampling sites north-west of the industrial unit. Contents of Cd, Cr, Cu, Ni, Pb, Mo, Sb, Sn, and Zn in soils and pollution load index (PLI) were highly correlated with mass specific magnetic susceptibility (χ lf ). Similarly, enrichment factor (EF) and geoaccumulation index (I geo ) for "technogenic" Pb and Zn exhibited high positive correlation factors with χ lf . Principal component analysis (PCA) classified PHEs along with the magnetic variable (χ lf ) into a common group indicating anthropogenic influence. The water extractable concentrations were substantially low, while the descending order of UBM (Unified BARGE Method) extractable concentrations in the gastric phase was Zn > Pb > As > Cd, yet Cd showed the highest bioaccessibility (almost 95%).

    Full Text Available The Andaman and Nicobar Islands located southeast of Bay of Bengal in the Indian Ocean comprises of several small islands separated by sea over large distances which makes it impractical for electrifying all the islands by a single grid. A population of 380,581 (Census, 2011 living in these group of islands get their electricity demand catered through Diesel Generator Sets from 34 power houses with an aggregate capacity of 67.8 MW. Unavailability of any form of conventional fossil fuel reserves in the islands makes the diesel supplied in barges from southeastern coast of India as a sole lifeline for its power generation. Hence there is an urgent need for the development of a self sustainable model from non conventional energy resources to not only cater for the power demands but also to reduce the GHG emissions related with diesel powered generator sets. This paper discusses a self sustainable model for Andaman and Nicobar Islands that would cater the electrical demand through hydrogen produced from waste biomass resource which has a potential of replacing 86.65% of the diesel utilized in the diesel generator sets. The reduction in both the GHG emission and the cost of power generation would be evaluated to understand the impact of the self sustainable model on the environment and the livelihood of the local population of Andaman and Nicobar Islands

    The paper summarized the results of Phase 1 and Phase 2 surveys conducted based on `Agreement on the comprehensive survey of a coal transportation system in South Sumatra` concluded between NEDO and the Ministry of Mine and Energy in Indonesia. In addition to the data collection and site surveys made in Phase 1, conducted in Phase 2 were determination of sites for harbors, determination of a scenario on coal transportation from coal mines to harbors, optimization of the coal transportation system, social/economic assessment, and proposal on the optimum transportation system. The results of the simulation were as follows: It is the most advantageous to transport coal from coal deposit area to harbor by rail and from harbor to Paiton by barge weighed over 10,000 tons. Tanjung Api Api is the most advantageous as harbor. The production scale which is profitable became more than 15 million tons. The present coal price of PTBA is $25/t arriving Suralaya. The coal in this case is said to be 5500kcal/kg in quality, and the coal of the same quality to this is only profitable. 8 refs., 68 figs., 104 tabs.

    The US Environmental Protection Agency's Environmental Response Team analyzed samples taken from Marrow Marsh, Galveston Bay, Texas, to assess the efficacy of a bioremediation effort in the marsh following the Apex barges spill on July 28, 1990. Samples from the marsh had been collected over a 96-hour period following the first application of the bioremediation agent and then 25 days after the second application, which occurred 8 days after the first. Results of sample analyses to evaluate changes in the chemical characteristics of spilled oil failed to show evidence of oil degradation during the 96 hours after the initial treatment, but did show evidence of degradation 25 days after the second treatment-although differences between samples from treated and untreated sites were not evident. Because control areas had not been maintained after the second application, contamination by the bioremediation agent of previously untreated (control) areas may have occurred, perhaps negating the possibility of detecting differences between treated and control areas. Better preparedness to implement bioremediation and conduct monitoring might have increased the effectiveness of the monitoring effort

    The basic concept of an innovative advanced marine reactor MRX has been established by design study toward the goals of light-weightiness, compactness, and safety and reliability improvement with adoption of several new technologies. The MRX is the integral-type PWR aimed for use of ship propulsion. Adoption of a water-filled containment makes the reactor light-weighted and compact greatly. The total weight and volume of the reactor are 1600 tons and 1210 m 3 , which are equivalent to halves of the Mutsu, although the reactor power of MRX is three times greater. An engineered safety system of the MRX is a simplified passive system, function of which is confirmed by the safety analysis to be able to keep the reactor integrity even in a case of accident. Reliability of the system is evaluated by the PSA and revealed to have two orders smaller core damage occurrence frequency than existing PWRs. The MRX can be applied to an energy supply system of electricity and heat co-generation. Concept of the nuclear energy supply system is designed to generate electricity, heat and fresh water. The nuclear barge is shown to be a possible nuclear energy supply system with advantage of being easily moveable. (author)

    Industry's development which is in the center of Cikarang's industrial estate causes a considerable increase from 7% to 13% of container's flow from and to Port of Tanjung Priok per year. Therefore, those obstacles rise the number of traffic congestion and transport cost. This research aims to analyze the potential alternative of transportation in order to transport containers at the route of Tanjung Priok to Cikarang utilizing Inland Waterways Transport through Cikarang Bekasi Laut (CBL) river. This research will be conducted by comparing component of total logistic cost that emerging caused by container trucks and vessels. Self Propelled Container Barge (SPCB) is a pointed alternative transportation in which it is used to transport containers through the waterways. The result of analysis obtained that the capacity of Cikarang Bekasi Laut river is 18,558 roundtrip per year. Furthermore, the collaboration of 3 SPCB operations, as well payload 32 TEUS can decrease the amount of road traffic congestion/density of Cikarang-Port of Tanjung Priok as much as 18.6%. The cost of containers shipping per unit transported by truck is IDR 2.2 Million per TEUs, whereas containers shipping transported by Inland Waterways cost only IDR 1.8 Million per TEUs.

  7. Global hydroelastic model for springing and whipping based on a free-surface CFD code (OpenFOAM

    Directory of Open Access Journals (Sweden)

    Sopheak Seng

    2014-12-01

    Full Text Available The theoretical background and a numerical solution procedure for a time domain hydroelastic code are presented in this paper. The code combines a VOF-based free surface flow solver with a flexible body motion solver where the body linear elastic deformation is described by a modal superposition of dry mode shapes expressed in a local floating frame of reference. These mode shapes can be obtained from any finite element code. The floating frame undergoes a pseudo rigid-body motion which allows for a large rigid body translation and rotation and fully preserves the coupling with the local structural deformation. The formulation relies on the ability of the flow solver to provide the total fluid action on the body including e.g. the viscous forces, hydrostatic and hydrodynamic forces, slamming forces and the fluid damping. A numerical simulation of a flexible barge is provided and compared to experiments to show that the VOF-based flow solver has this ability and the code has the potential to predict the global hydroelastic responses accurately.

  8. Medium-size power plants. Economic options

    International Nuclear Information System (INIS)

    Vogelweith, L.; Baujat, J.; Goutail, J.

    1978-01-01

    In this paper the authors describe a method for economic evaluation of a nuclear power plant project such as advocated by the IAEA but modified through the introduction of various parameters that may affect the evaluation, i.e. the weighted evaluation rate, the annual increase in the cost of fuel, and the discount rate. The method is applied to barge-based medium-size reactors (125 MW(e)). The authors calculate the investment cost, together with the costs of administration, operation and maintenance; use is made of current assumptions regarding the price of fuel for the case of a reference nuclear plant and an oil-fired plant of the same power and in the same programme. In this way the authors derive the discounted cost of the nuclear programme and concurrent conventional programme on the basis of the following assumptions: a weighted inflation rate varying between 0 and 6% per year; an annual increase in real fuel prices ranging from 0 to 3%; and a real discount rate, equal to the real interest rate, varying between 4 and 7% per year and corresponding to nominal discount rates of up to 13.4%. The conclusion reached is that, given the real interest rates actually prevailing on the financial market, a weighted inflation rate foreseen by the majority of experts, and a rise in real fuel prices of the order of 1% per year, the medium-size nuclear power plant is more economical than a conventional plant of the same output.

    James M. Craven

    2015-01-01

    Full Text Available Material feeding and handling systems have been cited as one of the most common causes of process downtime where thermochemical conversion processes are concerned. New and emerging fuels come in a variety of forms, and if such fuels are to be deployed widely it is imperative that material feeding and handling systems are designed appropriately. This study proposes an approach for designing material feeding and handling systems for use with coarse solid fuels. The data obtained from this study indicates particle size to be one of the key issues affecting the flowability of bulk solids further to the uniformity in particle shape. Coarse bulk solid samples were shown to flow more freely than their milled and pulverised counterparts, generating higher degrees of flowability. The results from this study were also applied to a new feed system used for feeding solid fuels to high pressure processes named the Hydraulic Lock Hopper. In this study the Hydraulic Lock Hopper demonstrated the feeding of wood pellets, torrefied spruce pellets, and ground anthracite coal grains against a pressure of 25 barg in two modes of operation. Energy savings compared to conventional lock hopper systems were recorded in the region of 80%.

    The first Swedish offshore wind farm Bockstigen is operating since March 1998 near the coast of Gotland. It was built as a demonstration project by the Swedish wind farm developer Vindkompaniet, the Danish wind turbine manufacturer Wind World and the British offshore construction company Seacore and partly funded under the EU-THERMIE program. Bockstigen is the fourth offshore wind farm world-wide. While at previous wind farms the main emphasis laid on the demonstration of the technical feasibility of offshore wind energy utilisation, Bockstigen was aimed at demonstrating its economic viability. A number of innovative concepts have been employed: Drilled monopile foundations were used to save costs. A new construction method has been applied making use of a jack-up barge. A new control system for the turbines and the whole wind farm was developed, which controls the maximum power output, the flicker and the reactive power consumption depending on online measurements of the actual grid state. These new developments have been implemented successfully. A substantial cost reduction compared to previous offshore projects could be achieved. (au)

  12. THE PROCEDURE FOR CALCULATION OF THE OPTIMAL CARRYING CAPACITY OF PUSHED CONVOY BASED ON PARAMETERS OBTAINED BY EXPERIMENTS IN ACTUAL NAVIGATING CONDITIONS

    Directory of Open Access Journals (Sweden)

    Ivan Škiljaica

    2015-06-01

    Full Text Available Exploitation and technical parameters of a ship are very important qualitative characteristics which determine the efficiency of the use of any kind of transportation vessels both for pushboats and for pushed convoys as a whole. Some of the most important exploitation and technical parameters are: parameter of transport efficiency, tonnage quality parameter, and thrust output of propeller. The complexity of these parameters can be seen from the fact that they present the values of achieved payload-distance during transportation of cargo in the unit of time per unit of installed (or effective power of propelling engines of ships. The most reliable means for determining the transport efficiency is the method of testing in actual navigating conditions, which is conducted in order to determine exact technical characteristics of propelling engines of pushboats, and to determine drawbacks in their work and to increase their thrust and speed characteristics. This paper will present the process of choosing the size, shape, and number of barges in the convoy based on experiments conducted on a pushboat whose propelling engines have installed power 3×809.6 kW (3×1,100 HP. Obtained results are based on presumption that the total resistance of a pushed convoy is equal to the total thrust achieved by the ship’s propelling complex.

  14. Oil spill studies: A review of ecological effects

    Science.gov (United States)

    Teal, John M.; Howarth, Robert W.

    1984-01-01

    We reviewed seven particularly well known and/or studied oil spills that have occurred since the National Academy of Sciences 1975 report, “Petroleum in the Marine Environment” or that occurred prior to that report but about which significant new information has since been acquired. The spills studied were from the barge Florida, and tankers Arrow, Argo Merchant, Amoco Cadiz, and Tsesis and blowouts from the Bravo and Ixtoc I platforms. These “best” studies yield only limited insight into effects because they lack controls and have a high degree of natural variability. The Tsesis, Florida, and Amoco Cadiz cases are exceptional since they occurred in areas of ongoing research programs and had nearby areas suitable for controls. Oil spills have produced measurable effects on ecosystems that have not been readily predictable from laboratory studies on isolated organisms. However, ecosystemlevel interactions are poorly understood even without the complications resulting from effects of pollution. These generalizations emerge: oil regularly reaches sediments after a spill; oil in anoxic sediments is persistent; oil regularly contaminates Zooplankton and benthic invertebrates; fish are also contaminated, but to a lesser extent; oil contamination decreases the abundance and diversity of benthic communities.

  15. Longitudinal review of state-level accident statistics for carriers of interstate freight

    International Nuclear Information System (INIS)

    Saricks, C.; Kvitek, T.

    1994-03-01

    State-level accident rates by mode of freight transport have been developed and refined for application to the US Department of Energy's (DOE's) environmental mitigation program, which may involve large-quantity shipments of hazardous and mixed wastes from DOE facilities. These rates reflect multi-year data for interstate-registered highway earners, American Association of Railroads member carriers, and coastal and internal waterway barge traffic. Adjustments have been made to account for the share of highway combination-truck traffic actually attributable to interstate-registered carriers and for duplicate or otherwise inaccurate entries in the public-use accident data files used. State-to-state variation in rates is discussed, as is the stability of rates over time. Computed highway rates have been verified with actual carriers of high- and low-level nuclear materials, and the most recent truck accident data have been used, to ensure that the results are of the correct order of magnitude. Study conclusions suggest that DOE use the computed rates for the three modes until (1) improved estimation techniques for highway combination-truck miles by state become available; (2) continued evolution of the railroad industry significantly increases the consolidation of interstate rail traffic onto fewer high-capacity trunk lines; or (3) a large-scale off-site waste shipment campaign is imminent

    2000-01-01

    It has been learned that to cope with energy requirement in the remote islands and less developed regions of Indonesia, small or very small nuclear reactors producing electricity and/or process heat could be appropriately applied. The barge mounted propulsion power reactors are the attractive examples so far envisioned, and technology information of which is being exposed to the world these last years. The solutions for least maintenance and no on-site refueling, no radioactive discharge, and no radioactive waste to remain in the user country are among the attractions for further deliberations. It has been understood, however, that there are many uncertainties to overcome, especially for the developing countries to introduce this novel application. International acceptance is the most crucial, availability of first-of-the-kind engineering, prototype or reference plant that would prove licensibility in the vendor's country is the second, and economic competitiveness due to very small size is the third among issues to enlighten. The relevant regulations concerning marine nuclear safety, marine transportation, and proliferation of information, as well as international forums to justify the feasibility of related transfer of technology, are the items that the IAEA could help to provide to smoothen any possible international transaction. Indonesia supports this AGM as one of the appropriate IAEA efforts in this line, and expects from it positive international consensus and possible studies/R and D work that this country could participate in.

    2015-01-01

    Full Text Available In order to explore marine natural resources using remote robotic sensor or to enable rapid information exchange between ROV (remotely operated vehicles, AUV (autonomous underwater vehicle, divers, and ships, ultrasonic underwater communication systems are used. However, if the communication system is applied to rich living creature marine environment such as shallow sea, it suffers from generated Impulsive Noise so-called Shrimp Noise, which is randomly generated in time domain and seriously degrades communication performance in underwater acoustic network. With the purpose of supporting high performance underwater communication, a robust digital communication method for Impulsive Noise environments is necessary. In this paper, we propose OFDM ultrasonic communication system with diversity receiver. The main feature of the receiver is a newly proposed Frequency Domain Diversity Combined Impulsive Noise Canceller. The OFDM receiver utilizes 20–28 KHz ultrasonic channel and subcarrier spacing of 46.875 Hz (MODE3 and 93.750 Hz (MODE2 OFDM modulations. In addition, the paper shows Impulsive Noise distribution data measured at a fishing port in Okinawa and at a barge in Shizuoka prefectures and then proposed diversity OFDM transceivers architecture and experimental results are described. By the proposed Impulsive Noise Canceller, frame bit error rate has been decreased by 20–30%.

    2016-12-01

    Full Text Available In this paper, hydrodynamic wave loads on an offshore stationary–floating oscillating water column (OWC are investigated via a 2D and 3D computational fluid dynamics (CFD modeling based on the RANS equations and the VOF surface capturing scheme. The CFD model is validated against previous experiments for nonlinear regular wave interactions with a surface-piercing stationary barge. Following the validation stage, the numerical model is modified to consider the pneumatic damping effect, and an extensive campaign of numerical tests is carried out to study the wave–OWC interactions for different wave periods, wave heights and pneumatic damping factors. It is found that the horizontal wave force is usually larger than the vertical one. Also, there a direct relationship between the pneumatic and hydrodynamic vertical forces with a maximum vertical force almost at the device natural frequency, whereas the pneumatic damping has a little effect on the horizontal force. Additionally, simulating the turbine damping with an orifice plate induces higher vertical loads than utilizing a slot opening. Furthermore, 3D modeling significantly escalates and declines the predicted hydrodynamic vertical and horizontal wave loads, respectively.

    1981-12-01

    A description of the organizational structure, resource, and plant design for an OTEC system near Key West, Fla., is presented. A consortium of government offices has contracted with individual industrial developers to form an initial design team and manage subcontracting. Key West was chosen because of high electric rates, a proximity to warm and deep seawater, and a cooperative utility. Ocean water temperatures range from 80 F for the surface to 42 F for deep waters. A 40 MWe pilot plant is planned, with a double hull design for the 600-700 ft by 100-200 ft barge; four 15 MWe power modules will use ammonia as a working fluid. Strong available currents have reduced the needed sizes of the surface water intake ducts; less than two weeks down time are projected for hurricanes. The fiber reinforced composite cooling water pipe will be 2,600 ft long and designed to withstand hurricane stresses. Mooring and power delivery cabling are described, and it is noted that the design for the Key West plant is transferable to anywhere in the world due to the built-in engineering considerations.

    The commonly adopted method of dumping dredge spoil at sea using split-hull barges leads to considerable sediment loss to the water column and a subsequent dispersion of fine material that can pose a risk to sensitive "downstream" habitats such as coral reefs. Containing sediment loads using stitched closed geotextile bags is practiced for minimizing loss of contaminated sediment, but is expensive in terms of operational efficiency. Following promising observations from initial laboratory trials, the plunging of partially shielded sediment loads, released on open sea, was studied. The partial shielding was achieved with rigid, open containers as well as flexible, open bags. The loss of sediment from these modes of shielding was measured, and it was observed that even limited and unstitched shielding can be effective in debilitating the entrainment of water into the descending load. In particular, long-sleeved flexible bags practically self-eliminated the exposure of the load and thus losses. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Ingestion of dust or soil particles could pose a potential health risk due to long-term metal trace element (MTE) exposure. Twenty-seven urban topsoil samples (kitchen garden and lawn) were collected and analyzed for Cd, Pb and Zn using the unified Bioaccessibility Research Group of Europe (BARGE) method (UBM) test to estimate the human bioaccessibility of these elements. The quantities of Cd, Pb and Zn extracted from soils indicated, on average, 68, 62 and 47% bioaccessibility, respectively, in the gastric phase and 31, 32 and 23% bioaccessibility, respectively, in the gastro-intestinal phase. Significant positive correlations were observed between concentrations extracted with UBM and total MTE contents. Stepwise multiple regression analysis showed that human bioaccessibility was also affected by some physico-chemical soil parameters (i.e. total nitrogen, carbonates, clay contents and pH). The unified test presents some valuable data for risk assessment. Indeed, the incorporation of oral bioaccessible concentrations into risk estimations could give more realistic information for health risk assessment.

  3. Elementary Physics Considerations Indicate an Elegant Construction Technique For the Pyramids At Giza. Our Information Indicates They and the Sphinx Were Engineered and Built Around BCE 2500, Not Earlier!

    Archimedes articulated an applied physics experience of many children who observe the upward movement of floating objects when they get into their "tubs." This same principle can effectively allow massive Egyptian construction blocks and obelisks to be elevated and erected. Platform bases at Giza were leveled by means of water channels that were cut into the rock. There is a canal behind the pyramids. The bathtub technique can elevate or transport the water-borne block (or obelisk) to sites involved, including the Sphinx temple. Water outflow from the barge locks (tubs) can erode Sphinx surrounds, without invoking 7000+ year-ago rainy weather. Our previously detailed account of how constellations, Canis Major, Phoenix, Leo can be detected at sites like America's Stonehenge, while they are below the local horizon, also indicates ancient Egyptians may have done likewise. Orion, or Leo the Sphinx could have been detected while they were in the "underground," around BCE 2500, in alignments otherwise requiring a date of BCE 1050.

    Fragments of flaking paint have been sampled from eighteen boats (including sailing barges, houseboats, a trawler and a ferry) abandoned on the intertidal mudflats of two estuaries in eastern England and analysed for Cu, Pb and Zn by X-ray fluorescence (XRF) spectrometry. Median concentrations of Pb on each boat ranged from about 350 to 35,000 μg g(-1), with individual concentrations exceeding 200,000 μg g(-1) in several cases. Median concentrations of Cu and Zn ranged from about 50 to 1900 μg g(-1) and 50 to 10,000 μg g(-1), respectively, with respective maxima of 172,000 μg g(-1) and 239,000 μg g(-1). Because of peeling paint, local sediment (analysed by ICP following acid digestion) was often measurably contaminated by the metals and, based on median, Al-normalised enrichment factors, in the order Pb>Zn>Cu. Due to its abundance and persistence in old paints, Pb is of greatest concern from both environmental and human health perspectives. Copyright © 2014 Elsevier B.V. All rights reserved.

    Lead (Pb) is a non-threshold toxin capable of inducing toxic effects at any blood level but availability of soil screening criteria for assessing potential health risks is limited. The oral bioaccessibility of Pb in 163 soil samples was attributed to sources through solubility estimation and domain identification. Samples were extracted following the Unified BARGE Method. Urban, mineralisation, peat and granite domains accounted for elevated Pb concentrations compared to rural samples. High Pb solubility explained moderate-high gastric (G) bioaccessible fractions throughout the study area. Higher maximum G concentrations were measured in urban (97.6 mg kg(-1)) and mineralisation (199.8 mg kg(-1)) domains. Higher average G concentrations occurred in mineralisation (36.4 mg kg(-1)) and granite (36.0 mg kg(-1)) domains. Findings suggest diffuse anthropogenic and widespread geogenic contamination could be capable of presenting health risks, having implications for land management decisions in jurisdictions where guidance advises these forms of pollution should not be regarded as contaminated land.

  7. Specifications for offshore pipeline - an analysis of installers needs versus manufacturers capabilities; Especificacoes para tubulacoes off-shore - uma analise das necessidades do instalador versus capacidade dos fabricantes

    The development of off-shore gas fields on the last years led to a sophistication on the methods of laying the pipes. This consequently led to specifications more and more stringent on the characteristics of the pipes that may interfere with the weld in barges or ships, notoriously when using automatic girth welding. The main restrictions are on pipe length, and dimensional characteristics such as: straightness; out of roundness; weld off-set, as well as chemistry. To cope with this trend the pipe mills had to make new developments and investments, and the cost of production of the pipes increased. Considering the real needs of the final customer, we concluded that some requirements are too stringent, leading to a final increase of the final cost of the installed pipeline, as some requirements that apparently save some installation costs, are difficult to be obtained during pipe fabrication, and cause increase on the final cost of it. This paper was made considering UOE/Three bend roll-SAW pipes, diameter 24'' and bigger. (author)

  8. CONTAINER TERMINALS IN EUROPE

    2001-01-01

    Full Text Available This paper aims to address the linkage between logistics (in particular, the management of marketing channel flows and transport markets, while also the interaction between these two markets and intermodal container terminals is analysed. The marketing channel theory is used to describe all relevant actors and flows that run through marketing channels, starting with customer needs and ending with customer satisfaction. Porter's theory of competitive advantages is used to review competitive forces in both markets. Finally, a competitor analysis is performed for the logistics and transport market. These theories are applied so as to be able to determine the competitive position of intermodal container terminals with a view to the management of marketing channel flows and the physical transport of freight flows. Hence, the central question of this paper is: Which markets are served by intermodal container terminals and with whom are they competing? At present, neither the maritime container terminals nor the continental container terminals appear to have a significant influence in the logistics service market; they concentrate mainly on the physical movement of containers (transshipment. Furthermore, maritime container terminals and continental container terminals are not dominant players in the transport service market. Our conclusion is that continental terminals are predominantly competing with unimodal road transport, with neighbouring continental terminals and with barge transport companies.

    Full Text Available The Costa Concordia cruise-ship disaster occurred just off the coast of Italy on January 13th, 2012, and entailed the largest marine salvage operation in history. The salvage employed vessels from different European harbours, providing an unexpected means for transporting alien species into the Mediterranean. In this work we identified mussel species using fragments length polymorphism of a nuclear locus and report the first evidence of the transport of the blue mussel, Mytilus edulis Linnaeus, 1758 (Bivalvia: Mollusca, into the Mediterranean Sea, as a part of the fouling community of the hull of an accommodation barge arrived from a NE Atlantic location in October 2012. Furthermore, we describe the rapid growth of this species, under the ASV Pioneer, until its almost total extinction during the summer of 2013, which left a covering of mussel shells on the underlying Posidonia oceanica (Linnaeus Delile, 1813. meadow. This high mortality rate indicated that M. edulis had been exposed to high stress conditions, probably due to different salinity, temperature, and oligotrophic conditions from its place of origin, and there was no spawning event or known settlement on the nearest infralittoral natural habitats. This event reminds us of how the Mediterranean Sea is constantly under alien-species pressure, due to human activities.

  10. Mobile inert gas generator for attic oil recovery

    Attic oil is usually defined as that oil which is trapped upstructure of the structurally highest producible well in a reservoir. If it is not economically feasible to drill a well for this oil accumulation, attic oil recovery by gas displacement is a possible secondary recovery method. The mechanics of the method are that gas is injected into the structurally highest well, the gas migrating up dip into the attic, forcing the oil downdip where it can be produced from the injection well or other wells in the reservoir. Where natural gas is in short supply or if injected gas cannot be recovered, inert gas generators for gas injection have a practical application. Oil accumulations found over and around piercement-type salt domes, such as the Bayou Des Allemands field, are usually excellent prospects for attic oil recovery by inert gas injection. After an economical comparison between recovery by natural gas or inert gas injection, it was found that the inert gas generator would be advantageous; therefore, an inert gas generator mounted on a cement barge was purchased. This study deals with this equipment which has now been in operation for one yr.

    Hydrocarbon deposits in the Beaufort Sea and Mackenzie Delta indicate mean discovered gas reserves of 5 trillion cubic feet of natural gas, 67 million barrels of condensate, and 247 million barrels of oil in fields located onshore. There may be even bigger undiscovered reserves that could be proven by a surge in drilling likely to occur in this region within the next few years. There are a number of characteristics of this area that appeal to the oil and gas industry over and above the discovered and undiscovered reserves. There is a local aboriginal group with a settled land claim, clear and reasonable rules for access, a business-like approach to development and a sophisicated understanding of the oil and gas industry. There is reasonable access by road, commercial air service, rail and barge by Hay river or sea with an excellent harbour at Tuktoyaktuk. Local contractors and labour with applicable skills and good equipment are available. The Inuvialuit Petroleum Corp. and its partners Altagas Services Inc. and Enbridge Inc. completed a project to supply the town of Inuvik with natural gas for electricity generation and local distribution. This project is a small example of the physical, economic and regulatory environments that the oil industry will face with the undertaking of larger projects. Aspects of the region described include: the Inuvialuit, recent experience, logistics, regulatory environment, project approvels, environmental, and specific observations

    In addition to arranging for storage and disposal of radioactive waste, the US Department of Energy (DOE) must develop a safe and efficient transportation system in order to deliver the material that has accumulated at various sites throughout the country. The ability to transport radioactive waste safely has been demonstrated during the past 20 years: DOE has made over 2,000 shipments of spent fuel and other wastes without any fatalities or environmental damage related to the radioactive nature of the cargo. To guarantee the efficiency of the transportation system, DOE must determine the optimal combination of rail transport (which allows greater payloads but requires special facilities) and truck transport Utilizing trucks, in turn, calls for decisions as to when to use legal weight trucks or, if feasible, overweight trucks for fewer but larger shipments. As part of the transportation system, the Facility Interface Capability Assessment (FICA) study contributes to DOE`s development of transportation plans for specific facilities. This study evaluates the ability of different facilities to receive, load and ship the special casks in which radioactive materials will be housed during transport In addition, the DOE`s Near-Site Transportation Infrastructure (NSTI) study (forthcoming) will evaluate the rail, road and barge access to 76 reactor sites from which DOE is obligated to begin accepting spent fuel in 1998. The NSTI study will also assess the existing capabilities of each transportation mode and route, including the potential for upgrade.

    2007-01-01

    The proposed Mackenzie Gas Project (MGP) is a 1220-kilometre natural gas pipeline system along the Mackenzie Valley of Canada's Northwest Territories. The line will connect northern onshore gas fields with North American markets. Four major Canadian oil and gas companies and a group representing the Aboriginal peoples of Canada's Northwest Territories are partners in the proposed MGP. The MGP is currently in the project definition stage that involves examining the effect of the project on northern communities. Fort Simpson is located on an island, on the forks of the Mackenzie and Liard Rivers and is proposed as the major route for the MGP with the construction of barge handling areas, storage areas, camps/housing units and use of air and highway facilities. These activities are expected to result in burden on local civil infrastructure systems including water supply systems. Although the environmental impacts of the project on the community's infrastructure systems are projected by the MGP proponents, the local authority wanted to conduct its own assessment of the impacts on local water supply system. This paper presented the results of a study that examined the amount of water used by the community based upon available water use records and the current operational and maintenance costs based upon available financial documents. The study also estimated future water requirements based upon MGP activities and associated population growth. Current and future economic rates were also determined. 13 refs., 6 tabs

    Power systems in rural Alaska villages face a unique combination of challenges that can increase the cost of energy and lowers energy supply reliability. In the case of the remote village of Shungnak, diesel and heating fuel is either shipped in by barge or flown in by aircraft. This report presents a technical analysis of several energy infrastructure upgrade and modification options to reduce the amount of fuel consumed by the community of Shungnak. Reducing fuel usage saves money and makes the village more resilient to disruptions in fuel supply. The analysis considers demand side options, such as energy efficiency, alongside the installation of wind and solar power generation options. Some novel approaches are also considered including battery energy storage and the use of electrical home heating stoves powered by renewable generation that would otherwise be spilled and wasted. This report concludes with specific recommendations for Shungnak based on economic factors, and fuel price sensitivity. General conclusions are also included to support future work analyzing similar energy challenges in remote arctic regions.

    2015-12-01

    The sizing of cryogenic safety relief devices requires detailed knowledge on the evolution of the pressure increase in cryostats following hazardous incidents such as the venting of the insulating vacuum with atmospheric air. Based on typical design and operating conditions in liquid helium cryostats, the new test facility PICARD, which stands for Pressure Increase in Cryostats and Analysis of Relief Devices, has been constructed. The vacuum-insulated test stand has a cryogenic liquid volume of 100 liters and a nominal design pressure of 16 bar(g). This allows a broad range of experimental conditions with cryogenic fluids. In case of helium, mass flow rates through safety valves and rupture disks up to about 4kg/s can be measured. Beside flow rate measurements under various conditions (venting diameter, insulation, working fluid, liquid level, set pressure), the test stand will be used for studies on the impact of two-phase flow and for the measurement of flow coefficients of safety devices at low temperature. This paper describes the operating range, layout and instrumentation of the test stand and presents the status of the commissioning phase.

    Full Text Available The development of a portable oxygen concentrator is of prime significance for patients with respiratory problems. This paper presents a portable concentrator prototype design using the pressure/vacuum swing adsorption (PVSA cycle with a deep evacuation step (−0.82 barg instead of desorption with purge flow to simplify the oxygen production process. The output of the oxygen concentrator is a ~90 vol % enriched oxygen stream in a continuous adsorption and desorption cycle (cycle time ~90 s. The size of the adsorption column is 3 cm in diameter and 20 cm in length. A Li+ exchanged 13X nanosize zeolite is used as the adsorbent to selectively adsorb nitrogen from air. A dynamic model of the pressure and vacuum swing adsorption units was developed to study the pressurization and depressurization process inside the microporous area of nanosized zeolites. The describing equations were solved using COMSOL Multiphysics Chemical Engineering module. The output flow rate and oxygen concentration results from the simulation model were compared with the experimental data. Velocity and concentration profiles were obtained to study the adsorption process and optimize the operational parameters.

    This study addresses numerical analysis of the installation of a tripod foundation using a heavy lift vessel (HLV). Limiting sea states are firstly predicted in the frequency domain based on crane tip vertical motions using linear transfer functions. Then, numerical modelling and simulations are carried out in the time domain to analyse the coupled dynamic system taking into consideration of the nonlinearities of the system. In time-domain analysis, two lifting phases are brought into focus, i.e., the lift-off and the lowering phases. For the lift-off phase, two scenarios are considered, i.e., lift-off from the own deck of the HLV and lift-off from a transport barge. Moreover, comparative studies using two types of installation vessels, a floating vessel and a Jack-up, are investigated for the lowering process. Critical responses including the motions of the tripod and the lift wire tensions are presented and compared under various environmental and loading conditions.

    The Western part of the “Bassin Minier de Provence”, a former coal mining area, is still occupied by old polluting industries such as a coal-fired power plant and an alumina factory. In 2011 a preliminary outdoor dust survey was carried out in the area as the first step to an exposure and health risk assessment study. Dust samples were taken at 19 sites distributed across the study area, depending on the location of recreational areas used by children to play outdoors. Pseudo-total concentrations of Al, Zn and Pb were determined by ICP-MS and bioaccessible concentrations were estimated using the Unified BARGE Method. Exposure was calculated according to a scenario evaluation approach for dust ingestion and dermal contact routes. Estimation of health risk for exposure to Al, Zn and Pb in outdoor dust was based on the summation of individual risks for the oral and dermal routes. Results show that Al occurs in very high concentrations but mainly innon-bioaccessible forms, especially near the alumina plant. Zinc and Pb occur in low-average levels but mainly in bioaccessible forms. The estimated potential risk decreases according to Pb ≫ Al > Zn and is lower for the ingestion route. The preliminary results presented in this study indicate that, for Al and Zn, the outdoor dusts of the BMP represent an acceptable risk to children's health. However, the estimated hazard quotients suggest that there is some health risk associated to environmental Pb.

    During the last decade, issue management programs have been developed and used by a number of large corporations in the United States. These systems have generally been designed to help senior program managers identify issues, develop strategic plans, and resolve issues. These systems involve scanning and abstracting literature to create a database that is then used for 1) issue identification, 2) issue analysis, 3) priority assessment, 4) development of corporate position/strategic options, and 5) action planning and implementation. Most of the existing systems rely on staff to identify trends in the computerized output, analyze the importance of the issue to the company, and assist in developing corporate responses. The Department of Energy has recently developed an issue management system for the Office of Civilian Radioactive Waste Management's (OCRWM) transportation program. This system is designed to help DOE identify institutional issues related to radioactive waste transportation, analyze the issues, and resolve them in a manner that is responsive to interested parties. The system will contain pertinent information from DOE technical reports, other federal documents, correspondence, professional journals, popular literature, newsclips, legislation and testimony. The program is designed around a number of institutional issues including: prenotification, physical protection procedures; highway, rail, and barge routing; inspections and enforcement of shipments; emergency response; liability, cask design and testing; overweight trucks; rail service; modal mix; infrastructure improvements; training standards, and operational procedures

    Full Text Available Thermal degradation of waste plastics with the aim of producing liquid fuel is one of the alternative solutions to landfill disposal or incineration. The paper describes thermal conversion of polypropylene waste and analysis of produced liquid fuel that would satisfy ISO 8217-2012 requirements for a residual marine fuel. Single pass batch thermolysis processes were conducted at different own vapour pressures (20-80 barg that determined process temperature, residence time of intermediates what resulted in different yields of the liquid product. Obtained products were stabilized by rectification to achieve required standard flash point. Gas chromatography and 1H NMR spectrometry show aliphatic nature of the liquid product where majority of the compounds are isoalkanes and isoalkenes. Only lightest fractions boiling up to a temperature of 72 oC have significant amount of n-pentane. Distribution of aromatic hydrocarbons is not even along the boiling range. The fractions boiling at a temperature of 128 oC and 160 oC have the highest content of monocyclic arenes – 3.16 % and 4.09 % respectively. The obtained final liquid residual product meets all but one requirements of ISO 8217-2012 for residual marine fuels.DOI: http://dx.doi.org/10.5755/j01.ms.21.2.6105

    The survey was conducted based on 'Scope of work for detailed coal exploration in the Tebulan East block of the Merit Pila coal field, Sarawak, Malaysia' concluded on June 19, 1993 between NEDO and Global Mineral which owns the mining right. The field survey was for the geological survey, survey of conditions of open pit mining, and infrastructure survey. The confirmed/estimated coal amount totaled 22,65 million tons in 4 coal seams. The all sulfur content is low, approximately 0.12%. The heating value is 5,820 kcal/kg. As to the infrastructure, various conditions are good for transportation, shipping facilities, etc. from mine site to truck transport/barge transport/external route shipping. The drilling was planned to be made by open pit mining by the truck and shovel system, and the scale of the planned production was 0.3 million tons.

  6. arXiv A non-perturbative exploration of the high energy regime in $N_\\text{f}=3$ QCD

    CERN Document Server

    Dalla Brida, Mattia; Korzec, Tomasz; Ramos, Alberto; Sint, Stefan; Sommer, Rainer

    Using continuum extrapolated lattice data we trace a family of running couplings in three-flavour QCD over a large range of scales from about 4 to 128 GeV. The scale is set by the finite space time volume so that recursive finite size techniques can be applied, and Schr\\"odinger functional (SF) boundary conditions enable direct simulations in the chiral limit. Compared to earlier studies we have improved on both statistical and systematic errors. Using the SF coupling to implicitly define a reference scale $1/L_0\\approx 4$ GeV through $\\bar{g}^2(L_0) =2.012$, we quote $L_0 \\Lambda^{N_{\\rm f}=3}_{\\overline{\\rm MS}} =0.0791(21)$. This error is dominated by statistics; in particular, the remnant perturbative uncertainty is negligible and very well controlled, by connecting to infinite renormalization scale from different scales $2^n/L_0$ for $n=0,1,\\ldots,5$. An intermediate step in this connection may involve any member of a one-parameter family of SF couplings. This provides an excellent opportunity for tests ...

  7. Impact assessment of waste management options in Singapore.

    2006-03-01

    This paper describes the application of life cycle assessment for evaluating various waste management options in Singapore, a small-island city state. The impact assessment method by SimaPro is carried out for comparing the potential environmental impacts of waste treatment options including landfilling, incineration, recycling, and composting. The inventory data include gases and leachate from landfills, air emissions and energy recovery from incinerators, energy (and emission) savings from recycling, composting gases, and transport pollution. The impact assessment results for climate change, acidification, and ecotoxicity show that the incineration of materials imposes considerable harm to both human health and the environment, especially for the burning of plastics, paper/cardboard, and ferrous metals. The results also show that, although some amount of energy can be derived from the incineration of wastes, these benefits are outweighed by the air pollution (heavy metals and dioxins/furans) that incinerators produce. For Singapore, landfill gases and leachate generate minimal environmental damage because of the nation's policy to landfill only 10% of the total disposed wastes. Land transportation and separation of waste materials also pose minimal environmental damage. However, sea transportation to the landfill could contribute significantly to acidification because of the emissions of sulfur oxides and nitrogen oxides from barges. The composting of horticultural wastes hardly imposes any environmental damage. Out of all the waste strategies, the recycling of wastes offers the best solution for environmental protection and improved human health for the nation. Significant emission savings can be realized through recycling.

    The paper conducted a R and D on the handling of drilling equipment in drilling/collecting of submarine oil and the gas lift of artificial oil extraction technology. As to each equipment of a barge style handling system, conducted were assembly/adjustment/trial run on land and pipe handling experiments on sea. In the experiment, confirmed were pipe transfer function, lifting function, fitting function, grasping function, etc. In the ocean experiment, studied were pipe bending stress, Karman vortex control effects, etc. Relating to the gas lift system, experiments were made on confirmation of fabrication/performance of air compressor. Moreover, a technique of air transportation to the blowing inlet of the gas lift pipe was established by developing an air blowing system and fabricating a long-distance flexible pipe. Concerning the gas/liquid/solid three-phase separator, a cyclone separator was developed, and improvement in lifting efficiency was confirmed. Helped by these, the problems of the gas lift system were almost solved, and a possibility of the commercial-base production system was obtained. 2 refs., 182 figs., 47 tabs.

    The Oil Pollution Act of 1990 (``OPA``) and an even more problematic array of State pollution laws have raised the cost, and risk, of carrying oil into and out of the US. This report, prepared under contract to the US Department of energy`s Office of Domestic and International Policy, examines the impact of Federal and State oil spill legislation on the tanker market. It reviews the role of marine transportation in US oil supply, explores the OPA and State oil spill laws, studies reactions to OPA in the tanker and tank barge industries and in related industries such as insurance and ship finance, and finally, discusses the likely developments in the years ahead. US waterborne oil imports amounted to 6.5 million B/D in 1991, three-quarters of which was crude oil. Imports will rise by almost 3 million B/D by 2000 according to US Department of energy forecasts, with most of the crude oil growth after 1995. Tanker demand will grow even faster: most of the US imports and the increased traffic to other world consuming regions will be on long-haul trades. Both the number of US port calls by tankers and the volume of offshore lightering will grow. Every aspect of the tanker industry`s behavior is affected by OPA and a variety of State pollution laws.

    Were prepared two organoclays aiming at studying their adsorption properties. The clayssed were the Brazilian Bentongel and Argentina Green Lake. The clays were characterized and organoclays. Performed analyzes of X-Ray diffraction, infrared, SEM, thermogravimetry and swelling experiments Foster and adsorption ASTM. The X-ray diffraction indicated collation of lamellar organic cation used. The variations thermogravimetrics were negative and ranged from around 24% in organophilic clays. The results of infrared spectroscopy indicated the presence of bands that show this barge. The form of the particles/agglomerates of clay minerals was verified by SEM before and after organofilization. The values of the measures of swelling were up to 30 mL/g for some solvents. The adsorption test showed good ability of sorption per gram of clay, reaching respectively 10.2g/g and 9.9 g/g for gasoline and ethylbenzene. These high values indicate that the modified clay may have potential use in sectors of environmental toxicity control industrial and separation. (author)

    In September 1969, the Florida barge spilled 700,000 L of No. 2 fuel oil into the salt marsh sediments of Wild Harbor, MA. Today a substantial amount, approximately 100 kg, of moderately degraded petroleum remains within the sediment and along eroding creek banks. The ribbed mussels, Geukensia demissa, which inhabit the salt marsh creek bank, are exposed to the spilled oil. Examination of short-term exposure was done with transplantation of G. demissa from a control site, Great Sippewissett marsh, into Wild Harbor. We also examined the effects of long-term exposure with transplantation of mussels from Wild Harbor into Great Sippewissett. Both the short- and long-term exposure transplants exhibited slower growth rates, shorter mean shell lengths, lower condition indices, and decreased filtration rates. The results add new knowledge about long-term consequences of spilled oil, a dimension that should be included when assessing oil-impacted areas and developing management plans designed to restore, rehabilitate, or replace impacted areas. - Mussels exposed to petroleum in transplant and field experiments exhibited significant long-term effects

    2002-01-01

    In 2000 the USA produced about 2.7 billion tonnes of aggregate worth about $13.7 billion. Both crushed stone and sand and gravel are produced in virtually every State, although limited quantities are available in the Gulf Coastal Plain, the Colorado Plateau , the Wyoming Basin and the Great Plains. Prices vary depending on the product and location. Most aggregates are transported by road, and minor amounts by railroad, barge on navigable inland channels, and through the Great Lake ports. Imports and exports of aggregates are very minor. A major amount f crushed stone aggregates is consumed by concrete aggregate. Recycled aggregates account for about 8% of total demand, although the amount recycled is thought to be increasing. Current issues facing the inductry unclude the differences in quality specifications between States, adjusting to the increasing concern for the impact of aggregate mining on the environmentm, health issues from particulate matter and crystalline silica, and the complexity of obtaining permits for extraction. Redcustion in the number od companies extracting aggregrates is likely to occur through acquisitions.

    Sub sea pipeline construction at oil and gas fields, with high concentration of on-bottom facilities, becomes more difficult when mooring operations and pipeline approach to a congested platform have to be performed. One method that has often been applied in Brazil is the so-called 'DP (Dynamic Positioning) pull-in', where PETROBRAS owned pipelay Barge, BGL-1, is moored away from the congested area, while a DP anchor handler pulls the rigid pipeline from BGL-1 to a target near the platform. The method was conceived to avoid mooring operations near the congested platforms as well as to minimize risks due to the pipeline initiation process. Inside the congested area the initiation with aid of a 'dead-man' anchor on the sea bottom, which would be a more conventional solution, becomes impossible in most cases. This paper will discuss the engineering work required to perform the 'DP pull-in' as well as show the operational steps, from the start-up to the final abandonment of the pipeline initiation head inside the target area.

    In 2006 and 2007 Terasen Pipelines (Trans Mountain) Inc. (now Trans Mountain Pipeline Inc.) submitted a series of applications to the National Energy Board for revisions to the Trans Mountain Tariffs. They were filed in response to apportionment concerns on the Trans Mountain pipeline. Four of the applications involved pronounced and contentious changes to the capacity allocation procedures on the pipeline system. For ease of reference, the Board amalgamated its 4 decisions on these applications into a single document. A map of the Trans Mountain pipeline system as a whole was presented along with a detailed map indicating the delivery locations served by the system in the lower mainland of British Columbia and the state of Washington. The issues considered by the Board in each of these decisions included capacity allocation for Westridge Dock; capacity allocations to export destinations; common carriage requirements; and the need for creating a new barge subcategory. Relevant sections of the National Energy Board Act referred to in the decisions were highlighted. This document also listed the Trans Mountain Tariffs that have introduced notable revisions to the capacity allocation procedures on the system since September 2003. 16 refs., 2 figs., 3 appendices

    Full Text Available In Malaysia, Malacca River has long been the tourism attraction in Malacca. However, due to negligence, the river has been polluted by the litters thrown by tourists and even local residents, thus reflects a negative perception on Malacca. Therefore, this paper discusses about a fully automated river debris management system development using a stand-alone photovoltaic system. The concept design is to be stand alone in the river and automatically pull debris towards it for disposal. An off-grid stand-alone photovoltaic solar panel is used as renewable energy source connected to water pump and Arduino Uno microcontroller. The water pump rotates a water wheel and at the same time moves a conveyor belt; which is connected to the water wheel by a gear for debris collection. The solar system sizing suitable for the whole system is shown in this paper. The dumpster barge is equipped with an infrared sensor to monitor maximum height for debris, and instruct Arduino Uno to turn off the water pump. This system is able to power up using solar energy on sunny days and using battery otherwise.

    The paper studied a system to effectively use unused and low-grade thermal energy (cold heat and hot heat) in the Tokyo-Yokohama seaside area. For transportation of thermal energy, the batch transportation, that is, off-line system was discussed which uses insulated tank loaded barges and railroad freight trains. Thermal energy supply sources are 1) 0.3 million kW class thermal power plant, and 2) LNG storage base of 3 million ton/year class. Thermal energy users are Tokyo (Haneda) Airport D.H.C. (District Heating/Cooling Co.), MM 21 D.H.C. and Shin-Kawasaki D.H.C. The cold heat energy supplied to these three is about 1.5 million Mcal/daytimes300 days/year, and the hot heat energy supplied is about 1.33 million Mcal/daytimes150 days/year. Cold heat is obtained from seawater after the LNG vaporization, and hot heat from heat extracted from thermal turbine. Subcooled ice was selected for cold heat medium, and PCM-120A for hot heat medium. For batch transportation, an STL heat storage system is used which transports plastic capsules sealed with heat medium. Oil saving of 62,000 tons/year and CO2 reduction of about 53,000 tons/year can be expected. 85 figs., 98 tabs.

    Two studies were completed which evaluate the environmental impact of radioactive material transport. The first was a generic study which evaluated all radioactive materials and all transportation modes; the second addressed spent fuel and fuel-cycle wastes shipped by truck, rail and barge. A portion of each of those studies dealing with the change in impact resulting from alternative shipping methods is presented in this paper. Alternatives evaluated in each study were mode shifts, operational constraints, and, in generic case, changes in material properties and package capabilities. Data for the analyses were obtained from a shipper survey and from projections of shipments that would occur in an equilibrium fuel cycle supporting one hundred 1000-MW(e) reactors. Population exposures were deduced from point source radiation formulae using separation distances derived for scenarios appropriate to each shipping mode and to each exposed population group. Fourteen alternatives were investigated for the generic impact case. All showed relatively minor changes in the overall radiological impact. Since the radioactive material transport is estimated to be fewer than 3 latent cancer fatalities (LCF) for each shipment year (compared to some 300,000 yearly cancer fatalities or 5000 LCF's calculated for background radiation using the same radiological effects model), a 15% decrease caused by shifting from passenger air to cargo air is a relatively small effect. Eleven alternatives were considered for the fuel cycle/special train study, but only one produced a reduction in total special train baseline LCF's (.047) that was larger than 5%

    Underwater noise associated with the installation and operation of hydrokinetic turbines in rivers and tidal zones presents a potential environmental concern for fish and marine mammals. Comparing the spectral quality of sounds emitted by hydrokinetic turbines to natural and other anthropogenic sound sources is an initial step at understanding potential environmental impacts. Underwater recordings were obtained from passing vessels and natural underwater sound sources in static and flowing waters. Static water measurements were taken in a lake with minimal background noise. Flowing water measurements were taken at a previously proposed deployment site for hydrokinetic turbines on the Mississippi River, where sounds created by flowing water are part of all measurements, both natural ambient and anthropogenic sources. Vessel sizes ranged from a small fishing boat with 60 hp outboard motor to an 18-unit barge train being pushed upstream by tugboat. As expected, large vessels with large engines created the highest sound levels, which were, on average, 40 dB greater than the sound created by an operating hydrokinetic turbine. A comparison of sound levels from the same sources at different distances using both spherical and cylindrical sound attenuation functions suggests that spherical model results more closely approximate observed sound attenuation.

    The purpose-designed floating storage transfer station (FSTS) is helping move more coal to export in Venezuela`s Maracaibo Lake. The 64,400 dwt Bulk Wayuu, owned and operated by Italy`s Coeclerici Group, began operations for Carbones del Guasare (CdG) last July. Coeclerici beat a number of other companies to win the five year contract, estimated to be worth around 30 million dollars. The FSTS is permanently moored by chain lines at the entrance channel of Maracaibo Lake in 11.9 m water depth. Five holds give storage capacity of 61,600 t of coal, effectively doubling CdG`s stockpile capacity. Four 25 t Krupp grab cranes are used to unload 2200 dwt coal barges coming from the Santa Cruz de Mara terminal. Three mobile deck-mounted belt shiploaders load and trim the ocean going vessels berthed on the other side. In the first 8 months` operations, 3.43 mt of coal was shipped into 69 vessels. 1 fig., 3 photos.

    The purpose of the study described in this report is to summarize the various barriers to more widespread distribution of bio-fuels through our common carrier fuel distribution system, which includes pipelines, barges and rail, fuel tankage, and distribution terminals. Addressing these barriers is necessary to allow the more widespread utilization and distribution of bio-fuels, in support of a renewable fuels standard and possible future low-carbon fuel standards. These barriers can be classified into several categories, including operating practice, regulatory, technical, and acceptability barriers. Possible solutions to these issues are discussed; including compatibility evaluation, changes to bio-fuels, regulatory changes, and changes in the distribution system or distribution practices. No actual experimental research has been conducted in the writing of this report, but results are used to develop recommendations for future research and additional study as appropriate. This project addresses recognized barriers to the wider use of bio-fuels in the areas of development of codes and standards, industrial and consumer awareness, and materials compatibility issues.

  6. Dynamic motions of floating nuclear plants (FNP) due to waves and earthquakes and feasibility studies on the FNP

    This report has summarized results on feasibility studies on floating nuclear plants (FNP). To extend siting options of the nuclear plants, the FNP is one of the most promising plants next to a siting technology on a man-made island because the FNP is effectively isolated from horizontal earthquake motions and designing plants is expected to be standardized irrelevant to ground conditions. One idea among those on the FNP is that the floating body is moored in a calm basin protected by breakwaters. Technical tasks on dynamic response of the floating body due to waves, wind and earthquakes were investigated using both physical model tests and numerical simulation models. It is required for the breakwaters to reduce a wave height inside the basin to 1.0 m. To reduce transmitted waves through the breakwater to a certain limited level under which the FNP's response to the waves is accepted, conventional rubble mound breakwaters do not function. Additional facilities such as sheet-pile type structure are required at the shallow water region. In deeper water sea, a caisson type breakwater work well to prohibit the transmitted waves. 2-D numerical simulation model was developed to estimate the wave motions in and near the breakwater. Dynamic motion of the FNP in short-crested waves joined to a dolphin-link mooring system was investigated using numerical simulation and physical model tests with multi-directional wave makers. Wind force acting the power plant was included together with the wave force. It is confirmed that under the design forces a magnitude of the FNP dynamic motion was smaller than the limited one to operate the nuclear plant. Displacement of the mooring system and its force were also smaller than the limited conditions. Because vertical earthquake motions on the FNP are almost the same as the ground motion, pneumatic chambers at the bottom of the barge are installed. It is evaluated by the solution that high frequency vertical acceleration greater than 1

    The United States conducted 24 nuclear tests at Bikini Atoll with a total yield of 76.8 Megatons (MT). The Castle series produced about 60% of this total and included the Bravo test that was the primary source of contamination of Bikini Island and Rongelap and Utrok Atolls. One of three aerial drops missed the atoll and the second test of the Crossroads series, the Baker test, was an underwater detonation. Of the rest, 17 were on barges on water and 3 were on platforms on an island; they produced most of the contamination of islands at the atoll. There were 42 tests conducted at Enewetak Atoll with a total yield of 31.7 MT (Simon and Robison, 1997; UNSCEAR, 2000). Of these tests, 18 were on a barge over wateror reef, 7 were surface shots, 2 aerial drops, 2 under water detonations, and 13 tower shots on either land or reef. All produced some contamination of various atoll islands. Rongelap Atoll received radioactive fallout as a result of the Bravo test on March 1, 1954 that was part of the Castle series of tests. This deposition was the result of the Bravo test producing a yield of 15 MT, about a factor of three to four greater than the predicted yield that resulted in vaporization of more coral reef and island than expected and in the debris-cloud reaching a much higher altitude than anticipated. High-altitude winds were to the east at the time of detonation and carried the debris-cloud toward Rongelap Atoll. Utrok Atoll also received fallout from the Bravo test but at much lower air and ground-level concentrations than at Rongelap atoll. Other atolls received Bravo fallout at levels below that of Utrok [other common spellings of this island and atoll (Simon, et al., 2009)]. To avoid confusion in reading other literature, this atoll and island are spelled in a variety of ways (Utrik, Utirik, Uterik or Utrok).

    Full Text Available Although the elimination of refuse by means of incineration, as opposed to conversion into fertilizer, is in the long run a bad policy, it was chosen in this case for economic reasons and the agricultural conditions of this area. Nevertheless, it will be possible to add the necessary means for fertilizer conversion whenever future agricultural developments dictate their usefulness. After a series of very complete comparative studies as to the best means of transport, highway or waterway, it was decided to build a canals connecting the plant with a lake. By means of an inclined wharf the unloading of trash from barges is easily accomplished. The plant is divided into three zones: 1 The principal building, which houses trash and slag bins, the loading chutes of the incinerator ovens, and, at right angles, the unloading bay for the barges. 2 The incinerator itself, which includes electromechanical fixtures, two ovens, two electrofilters, a turbo-generator, the control center, and the slag evacuation chain. 3 Administrative offices, which contain workshops, warehouse, lunchroom, staff entrance and dressing rooms, lecture rooms, rest rooms, infirmary, laboratory and business offices. The construction is of reinforced concrete, aimed at creating a unified, exciting architectural appearance outstanding for its sharp contrasts of volumes.Aunque el sistema de eliminar los residuos por medio de la incineración, en lugar de transformarlos en abono, constituya a largo plazo una mala política, ha sido el elegido en este caso por razones de rentabilidad y por las condiciones económico-agrícolas actuales del territorio. Sin embargo, se ha previsto la posibilidad de que, en el futuro, pueda completarse con elementos de transformación en abono, siempre que la evolución de la economía agrícola demuestre su utilidad. Después de una serie muy completa de estudios comparativos entre el transporte por carretera y el fluvial, se decidieron por este último

    This report, the sixth in a series published since 1994, presents analyses of hydrologic data in Monroe County for the period October 2002 through September 2008. Streamflows and water quality were monitored at nine sites by the Monroe County Department of Health and the U.S. Geological Survey. Streamflow yields (flow per unit area) were highest in Northrup Creek, which had sustained flows from year-round inflow from the village of Spencerport wastewater-treatment plant and seasonal releases from the New York State Erie (Barge) Canal. Genesee River streamflow yields also were high, at least in part, as a result of higher rainfall and lower evapotranspiration rates in the upper part of the Genesee River Basin than in the other study basins. The lowest streamflow yields were measured in Honeoye Creek, which reflected a decrease in flows due to the withdrawals from Hemlock and Canadice Lakes for the city of Rochester water supply. Water samples collected at nine monitoring sites were analyzed for nutrients, chloride, sulfate, and total suspended solids. The loads of constituents, which were computed from the concentration data and the daily flows recorded at each of the monitoring sites, are estimates of the mass of the constituents that was transported in the streamflow. Annual yields (loads per unit area) also were computed to assess differences in constituent transport among the study basins. All urban sites - Allen Creek and the two downstream sites on Irondequoit Creek - had seasonally high concentrations and annual yields of chloride. Chloride loads are attributed to the application of road-deicing salts to the county's roadways and are related to population and road densities. The less-urbanized sites in the study - Genesee River, Honeoye Creek, and Oatka Creek - had relatively low concentrations and yields of chloride. The highest concentrations and yields of sulfate were measured in Black Creek, Oatka Creek, and Irondequoit Creek at Railroad Mills and are

    In 2006, the Engineer Research and Development Center (ERDC) began a program designed to meet the capability gap associated with remote assessment of critical infrastructure. This program addresses issues arising from the use of geophysical techniques to solve engineering problems through persistent monitoring of critical infrastructure using infrasound. In the original 2006-2009 study of a railroad bridge in Ft. Leonard Wood, MO, the fundamental modes of motion of the structure were detected at up to 30 km away, with atmospheric excitation deemed to be the source driver. Follow-on research focused on the mechanically driven modes excited by traffic, with directional acoustic emanations. The success of the Ft. Wood ambient excitation study resulted in several subsequent programs to push the boundaries of this new technique for standoff assessment, discussed herein. Detection of scour and river system health monitoring are serious problems for monitoring civil infrastructure, from both civilian and military perspectives. Knowledge of overall system behavior over time is crucial for assessment of bridge foundations and barge navigation. This research focuses on the same steel-truss bridge from the Ft. Wood study, and analyzes 3D and 2D substructure models coupled with the superstructure reaction loads to assess the modal deformations within the infrasound bandwidth and the correlation to scour of embedment material. The Urban infrasound program is infrasound modeling, data analysis, and sensor research leading to the detection, classification and localization of threat activities in complex propagation environments. Three seismo-acoustic arrays were deployed on rooftops across the Southern Methodist University campus in Dallas, Texas, to characterize the urban infrasound environment. Structural sources within 15 km of the arrays have been identified through signal processing and confirmed through acoustical models. Infrasound is also being studied as a means of

    -term altimeter measurements in relation with boat traffic data base demonstrate that boat-generated waves are the key hydrodynamic parameter controlling short term tidal flat evolution. Concerning hydrodynamics, two main types of boat-generated waves can be distinguished: one corresponds to barges, the other to sea vessels. The critical parameter controlling wave characteristics, bottom shear stress and thus sedimentary impacts is the distance between seabed and keel. Thus, considering their larger seabed-keel distance, barges do not significantly affect the sedimentary cover of the intertidal area. On the contrary, sea-vessels can induce rapid changes of the tidal flat texture (i.e. bed flattening, mud drapes...) and morphology: erosion and sedimentation rates in a range of 0.5 to 6 cm.min-1 have been measured. Such energetic events occur generally during the squat generated wave run-up and can affect the seabed in water depths up to 1.5 m. In the freshwater part of the Seine estuary annual sediment inputs are mostly controlled by river flow (during river flood) while medium term scale evolution is dependent on tidal range and short term sediment dynamics (i.e. bedload, resuspension) on sea-vessels waves.

    and disposal regulations and criteria or if special authorizations must be granted to transport and/or dispose. The U.S. DOT routinely issues special permits for large components where compliance with regulatory or acceptance criteria is impractical or impossible to meet. Transportation and disposal safety must be maintained even under special permits or authorizations. For example, if transported un-packaged, performance analysis must still be performed to assess the ability of the large component's outer steel shell to contain the internal radioactive contamination under normal transportation conditions and possibly incidence normal to transportation. The dimensions and weight of a large component must be considered when determining the possible modes of transportation (rail, water, or highway). At some locations, rail and/or barge access is unavailable. Many locations that once had an active rail spur to deliver new construction materials and components have let the spur deteriorate to the point that repair and upgrade of the spur is no longer economically feasible. Barge slips that have not been used since new plant construction require significant repair and/or dredging. Short on-site haul routes must be assessed for surface and subsurface conditions, as well as longer off-site routes. Off-site routes require clearance approvals from the regulatory authorities or, in the case of rail transport, the rail lines. Significant engineering planning and analysis must be performed during the pre-mobilization. In conclusion, the packaging, transportation, and disposal of large, oversized radioactively contaminated components removed during plant decommissioning is complex. However, over the last 15 years, a 100 or more components have been safely and compliantly packaged and transported for processing and/or disposal

    A novel biomimetic extraction procedure that allows for the in-line handing of ≥400 mg solid substrates is herein proposed for automatic ascertainment of trace element (TE) bioaccessibility in soils under worst-case conditions as per recommendations of ISO norms. A unified bioaccessibility/BARGE method (UBM)-like physiological-based extraction test is evaluated for the first time in a dynamic format for accurate assessment of in-vitro bioaccessibility of Cr, Cu, Ni, Pb and Zn in forest and residential-garden soils by on-line coupling of a hybrid flow set-up to inductively coupled plasma atomic emission spectrometry. Three biologically relevant operational extraction modes mimicking: (i) gastric juice extraction alone; (ii) saliva and gastric juice composite in unidirectional flow extraction format and (iii) saliva and gastric juice composite in a recirculation mode were thoroughly investigated. The extraction profiles of the three configurations using digestive fluids were proven to fit a first order reaction kinetic model for estimating the maximum TE bioaccessibility, that is, the actual worst-case scenario in human risk assessment protocols. A full factorial design, in which the sample amount (400-800 mg), the extractant flow rate (0.5-1.5 mL min(-1)) and the extraction temperature (27-37°C) were selected as variables for the multivariate optimization studies in order to obtain the maximum TE extractability. Two soils of varied physicochemical properties were analysed and no significant differences were found at the 0.05 significance level between the summation of leached concentrations of TE in gastric juice plus the residual fraction and the total concentration of the overall assayed metals determined by microwave digestion. These results showed the reliability and lack of bias (trueness) of the automatic biomimetic extraction approach using digestive juices. Copyright © 2014 Elsevier B.V. All rights reserved.

  14. Active structural control of a floating wind turbine with a stroke-limited hybrid mass damper

    2017-12-01

    Floating wind turbines are subjected to more severe structural loads than fixed-bottom wind turbines due to additional degrees of freedom (DOFs) of their floating foundations. It's a promising way of using active structural control method to improve the structural responses of floating wind turbines. This paper investigates an active vibration control strategy for a barge-type floating wind turbine by setting a stroke-limited hybrid mass damper (HMD) in the turbine's nacelle. Firstly, a contact nonlinear modeling method for the floating wind turbine with clearance between the HMD and the stroke limiters is presented based on Euler-Lagrange's equations and an active control model of the whole system is established. The structural parameters are validated for the active control model and an equivalent load coefficient method is presented for identifying the wind and wave disturbances. Then, a state-feedback linear quadratic regulator (LQR) controller is designed to reduce vibration and loads of the wind turbine, and two optimization methods are combined to optimize the weighting coefficients when considering the stroke of the HMD and the active control power consumption as constraints. Finally, the designed controllers are implemented in high fidelity simulations under five typical wind and wave conditions. The results show that active HMD control strategy is shown to be achievable and the designed controllers could further reduce more vibration and loads of the wind turbine under the constraints of stroke limitation and power consumption. "V"-shaped distribution of the TMD suppression effect is inconsistent with the Weibull distribution in practical offshore floating wind farms, and the active HMD control could overcome this shortcoming of the passive TMD.

    Full Text Available The evaluation of an almond collection using morphological variables and identification of self-incompatibility genotype  is useful for selecting pollinizers and for the design of crossing in almond breeding programs. In this study, important morphological traits and self-incompatibilities in 71 almond cultivars and genotypes were studied. Simple and multiplex specific PCR analyses were used in order to identify self-incompatibility alleles. Based on the results, cultivars and genotypes including ‘Dir Ras–e-Savojbolagh’, ‘D-124’, ‘D-99’, ‘Shahrood 12’, ‘Tuono’, ‘Nonpareil’, ‘Price’, ‘Mirpanj-e-Tehran’, ‘Pakotahe-e- Taleghan’, ‘V-13-34’, ‘V-16-8, ‘V-11-10’, ‘Zarghan 10’, ‘Uromiyeh 68’, ‘Barg dorosht-e-Hamedan’ and ‘Yazd 60’ were late flowering and had the highest quality of nut and kernel characters. The result of the PCR method using combined primers AS1II and AmyC5R showed amplification of ten self-incompatibility alleles (S1, S2, S3, S5, S6, S7, S8, S10, S12,and S unknown allele and three Sfalleles. Moreover, S1 had the highest frequencies in comparison with other known S-alleles. Also, unknown alleles with different sizes were detected and 58 new bands were found in some cultivars.

    The potential impacts associated with the transportation of hazardous materials are important to shippers, carriers, and the general public. This is particularly true for shipments of radioactive material. The shippers are primarily concerned with safety, security, efficiency, and equipment requirements. The carriers are concerned with the potential impact that radioactive shipments may have on their operations--particularly if such materials are involved in an accident. The general public has also expressed concerns regarding the safety of transporting radioactive and other hazardous materials through their communities. Because transportation routes are a central concern in hazardous material transport, the prediction of likely routes is the first step toward resolution of these issues. In response to these routing needs, several models have been developed over the past fifteen years at Oak Ridge National Laboratory (ORNL). The HIGHWAY routing model is used to predict routes for truck transportation, the INTERLINE routing model is used to predict both rail and barge routes, and the AIRPORT locator model is used to determine airports with specified criteria near a specific location. As part of the ongoing improvement of the US Department of Energy's (DOE) Environmental Management Transportation Management Division's (EM-261) computer systems and development efforts, a Baseline Requirements Assessment Session on the HIGHWAY, INTERLINE, and AIRPORT models was held at ORNL on April 27, 1994. The purpose of this meeting was to discuss the existing capabilities of the models and data bases and to review enhancements of the models and data bases to expand their usefulness. The results of the Baseline Requirements Assessment Section will be discussed in this report. The discussions pertaining to the different models are contained in separate sections

  17. A method for intermediate flooding and sinking simulation of a damaged floater in time domain

    Full Text Available When a floater such as a ship or an offshore structure is damaged in the sea, it is necessary to determine whether the floater will sink in water or not. If the floater will sink, the time to sink should be estimated to make an emergency plan. In addition, causes of the flooding should be investigated carefully. For this purpose, a method for performing intermediate flooding and sinking simulation of the damaged floater in time domain is proposed in this study. Overall process of the proposed method consists of several steps. In the first step, data of the damaged floater such as hull form and compartments are prepared. In the second step, physical characteristics of the floater such as the increased weight considering incoming water, the center of gravity, the changed buoyancy, and the center of buoyancy are calculated at every time step. In the third step, the quasi-static equilibrium position of the floater is calculated. The second and third steps are repeated until the floater reaches to sink or to be in equilibrium. As a result, the final condition of the floater can be determined. To check the feasibility of the proposed method, it is applied to a simple box problem. Finally, it is applied to intermediate flooding simulation of a barge-type damaged floater. Two cases having damaged holes of different locations are selected. As a result, it was confirmed that the floater can be in equilibrium or sink according to the damaged position. The time to be in equilibrium or the time to sink was estimated.

    Lead (Pb) is a non-threshold toxin capable of inducing toxic effects at any blood level but availability of soil screening criteria for assessing potential health risks is limited. The oral bioaccessibility of Pb in 163 soil samples was attributed to sources through solubility estimation and domain identification. Samples were extracted following the Unified BARGE Method. Urban, mineralisation, peat and granite domains accounted for elevated Pb concentrations compared to rural samples. High Pb solubility explained moderate-high gastric (G) bioaccessible fractions throughout the study area. Higher maximum G concentrations were measured in urban (97.6 mg kg −1 ) and mineralisation (199.8 mg kg −1 ) domains. Higher average G concentrations occurred in mineralisation (36.4 mg kg −1 ) and granite (36.0 mg kg −1 ) domains. Findings suggest diffuse anthropogenic and widespread geogenic contamination could be capable of presenting health risks, having implications for land management decisions in jurisdictions where guidance advises these forms of pollution should not be regarded as contaminated land. - Highlights: • Urban, mineralisation, peat and granite sources accounted for elevated Pb in soil. • Pb solubility was higher in urban and mineralisation domains. • Higher Pb solubility resulted in high oral bioaccessibility compared to rural areas. • Diffuse background and natural Pb contamination could pose human health risks. • Contaminated land policy should not dismiss diffuse or geogenic pollution sources. - Diffuse and widespread Pb sources displayed high oral bioaccessibility, providing implications for contaminated land risk assessment guidance that excludes these forms of pollution

    Despite a long history of human manipulation, the most dramatic changes in the upper Mississippi River occurred in the 1930s with construction of a lock and dam system to facilitate the commercial transport of commodities. In 1988, barge traffic through the system ranged from 7,500 tows per year at Lock and Dam 26 (near Alton, Illinois) to 1, 118 at Lock and Dam 1 (in Minneapolis/St. Paul). The tow-teed dam system created a diversity of lentic habitats, but it also changed the stage and sediment transport characteristics of the river. The principal fishery-related water quality issues of this modified system concern the effects of sediments and toxic contaminants from nonpoint sources. Between 42 and 99% of the streams in the five states of the Mississippi River basin fail to fully support their designated uses because of pollution. primarily from nonpoint sources (e.g., 73% in Minnesota, 98% in Wisconsin, 75% in Illinois). Annual sediment inputs into the upper Mississippi River basin range from minimal in the upper reaches to about 210.000 kg/hectare in the lower reaches. This sediment results in significant losses of fishery habitat. Although bnly 5 to 9% of the total open water area of many pools had been lost by 1975, those losses were in highly productive side channel and backwater areas. Under existing conditions, a loss of an additional 22 to 49% of existing lentic habitats is predicted within 50 years. In addition, toxic contaminants transported along with fine sediments have become more available to stream biota. Although significant interagency efforts have been made to evaluate the impacts on biotic communities of the river. present data are inadequate to determine how changes in water quality affect the fisheries. This lack of data undermines our ability to judge the success of programs initiated to control pollution from point and nonpoint sources.

    Energy costs in rural Alaskan communities are substantial. Diesel fuel, which must be delivered by barge or plane, is used for local power generation in most off-grid communities. In addition to high costs incurred for the purchase and transport of the fuel, the transport, transfer, and storage of fuel products pose significant difficulties in logistically challenging and environmentally sensitive areas. The Alaska Rural Energy Project (AREP) is a collaborative effort between the United States Geological Survey (USGS) and the Bureau of Land Management Alaska State Office along with State, local, and private partners. The project is designed to identify and evaluate shallow (Regional Corporation, and the Olgoonik Corporation, drilled and tested a 1,613 ft continuous core hole in Wainwright, Alaska, during the summer of 2007 to determine whether CBM represents a viable source of energy for the community. Although numerous gas-bearing coal beds were encountered, most are contained within the zone of permafrost that underlies the area to a depth of approximately 1,000 ft. Because the effective permeability of permafrost is near zero, the chances of producing gas from these beds are highly unlikely. A 7.5-ft-thick gas-bearing coal bed, informally named the Wainwright coal bed, was encountered in the sub-permafrost at a depth of 1,242 ft. Additional drilling and testing conducted during the summers of 2008 and 2009 indicated that the coal bed extended throughout the area outlined by the drill holes, which presently is limited to the access provided by the existing road system. These tests also confirmed the gas content of the coal reservoir within this area. If producible, the Wainwright coal bed contains sufficient gas to serve as a long-term source of energy for the community.

    Due to its advantageous thermodynamic characteristics at high temperature (550 deg. C), liquid sodium is the main candidate to be the cooling fluid for Generation TV nuclear reactors SFR (Sodium-cooled Fast Reactors). Now, sodium reacts very violently, both with the water and the oxygen of the air. Only few data were known about the liquid sodium behaviour when spread in the environment through micro defects. These are often present in a cooling circuit in welded or sealed joints and more rarely in the pipes. Micro defects, on the other hand, can be also generated in a cooling circuit because of the vibrations always present in a circuit into which a fluid runs. A new set-up, named LISOF, was built for testing high temperature liquid sodium when passing through micro defects and generating sprays or jets. Sprays and jets were generated by means of nozzles embedding sub milli-metric holes the diameter of which was: 0.2 mm, 0.4 mm, 0.5 mm. Tests were performed by pressurizing liquid sodium (550 deg. C) at: 3, 6 and 9 barg. Normal and high speed cinematography were used for the direct observation of the liquid sodium sprays while Phase Doppler Interferometry was used for the measurement of the droplets characteristics and velocity. Tests concerning the behaviour of the high temperature liquid sodium firing in air or in contact with the cement cover applied to a scaled down core catcher simulacrum were also performed. The paper presents the built set-up and the collected results. (authors)

    On August 24, 1992, Hurricane Andrew slammed into South Florida with wind gusts in excess of 160 mph. At 4:00 a.m. that day, the eye of this category four storm passed over Florida Power ampersand Light Company's Turkey Point power plant, south of Miami. Although the plant's two nuclear units escaped any significant damage, the storm caused extensive destruction to buildings and transmission facilities, and damaged two 400 foot tall emission stacks associated with the site's two fossil fuel generating units. In addition, a 90,000 to 110,000 gallon spill of No. 6 fuel oil resulted when a piece of wind-blown debris punctured the steel of the unit One 12,000 barrel fuel oil metering tank approximately 30 feet up from the tank bottom. Despite the presence of a secondary containment structure around the tank, the intense wind blew oil throughout the plant site. The damage to the metering tank apparently occurred during the first half hour of the hurricane. As the tank's oil level fell due to the puncture, transfer pumps from the bulk oil storage tanks received a low level alarm which automatically began transferring oil to the damaged metering tank. To prevent the further discharge of oil, plant personnel entered the power block and secured the pumps during the passage of the hurricane eye. Immediately following the storm, facility personnel deployed booms across the barge canal and the Units 1 and 2 intake canal to contain the oil which had entered the water. The response strategy and implementation is described in detail. The remediation costs were approximately $14/gallon spilled, including 54,000 gallons recovered for electricity generation

  4. Atlantic Canada : recipe for ruin, loophole in Canadian tanker laws questioned

    During a storm in December 2000, the captain of a leaking supertanker named the Eastern Power requested permission to dock his 339-metre ship at Come by Chance in Newfoundland. The request was denied by Transport Canada and the barge carrying 1.9 million barrels of oil had to ride out the storm just outside Canada's 200-mile limit. The concern was that the hull might split and spill huge amounts of oil. The Eastern Power has only one hull and is twice the age that the Prevention of Pollution from Ships considers reasonable for the lifespan of a vessel. Tankers built after 1993 are required to have an inside and an outside frame in order to enter Canadian waters. Those that are not double hulled and built before 1993 will be phased out by 2015. The spokesman for Transport Canada explained that the concern regarding the Eastern Power was for the Canadian environment. Owners are responsible for making sure that their ships do not risk our environment. An added precaution requires that all ships radio the Canadian Coast Guard 24 hours before reaching the 200-mile limit to report on their course, destination and seaworthiness. While Transport Canada makes the ultimate decision on entry, it shares the information with the Department of National Defense, Environment Canada and the coast guard. In this case, the crew of the Eastern Power was able to pump cargo into a safer tank and repaired the rupture. It was then given permission to dock at Come By Chance, but it instead headed for the Caribbean. Newfoundland is still recovering from the collapse of the cod fishery and is trying to build an eco-tourism industry given that its Atlantic offshore is a marine ecological treasure. Environmentalists view some of the present marine laws, or lack of laws, as a gateway to a disaster which could wipe out some water fowl species and further reduce fish stocks. 1 fig

    This study explores and verifies the generalized body-modes method for evaluating the structural loads on a wave energy converter (WEC). Historically, WEC design methodologies have focused primarily on accurately evaluating hydrodynamic loads, while methodologies for evaluating structural loads have yet to be fully considered and incorporated into the WEC design process. As wave energy technologies continue to advance, however, it has become increasingly evident that an accurate evaluation of the structural loads will enable an optimized structural design, as well as the potential utilization of composites and flexible materials, and hence reduce WEC costs. Although there are many computational fluid dynamics, structural analyses and fluid-structure-interaction (FSI) codes available, the application of these codes is typically too computationally intensive to be practical in the early stages of the WEC design process. The generalized body-modes method, however, is a reduced order, linearized, frequency-domain FSI approach, performed in conjunction with the linear hydrodynamic analysis, with computation times that could realistically be incorporated into the WEC design process. The objective of this study is to verify the generalized body-modes approach in comparison to high-fidelity FSI simulations to accurately predict structural deflections and stress loads in a WEC. Two verification cases are considered, a free-floating barge and a fixed-bottom column. Details for both the generalized body-modes models and FSI models are first provided. Results for each of the models are then compared and discussed. Finally, based on the verification results obtained, future plans for incorporating the generalized body-modes method into the WEC simulation tool, WEC-Sim, and the overall WEC design process are discussed.

    The Paraná River is one of the largest water courses in the world and along its reach in the Argentine territory, it receives a large load of sediments from the Pilcomayo and Bermejo Rivers, through the Paraguay River, in the upper basin at the North of Argentina and South of Bolivia. The suspended sediment load is estimated in 100 Million ton/year. This unique characteristic drives the Paraná River morphology downstream, as well as the Paraná delta morphodynamics. On top of its natural behaviour, the Paraná-Paraguay river system is an important inland waterway transport corridor, with a significant amount of sea going vessels and inland barges navigating throughout stretches of more than 3000 Km. Consequently, there are numerous port complexes and terminals along the river banks. The typical wet infrastructure of these terminals is usually composed by jetties and quay walls, and occasionally with side or lateral docks. Whereas, the case included within this study presents all these components. This study presents a hydrodynamic and sedimentology 3D model to predict the velocity fields and the associated shear stresses that will drive morphological processes in the lateral dock. The terminal layout, side dock configuration, and sedimentation issues will be analyzed from multidisciplinary point of view, under different hydrological events and considering the correlated sediment loads. Recent bathymetry studies had been carried out and this set of data will be implemented to build the domain geometry. The flow series is as well extended with the up to date gauged flows and levels, to carry out statistical analysis and identify the design flows for different probabilities. The main objective of this analysis will be to understand and identify the scour and deposition processes and the possible problems to the structures safety and the operation of the docks, and introduce variations to the baseline design, if necessary. Results will be contrasted and validated

  7. Economic impacts of oil spills: Spill unit costs for tankers, pipelines, refineries, and offshore facilities

    1993-01-01

    The impacts of oil spills -- ranging from the large, widely publicized Exxon Valdez tanker incident to smaller pipeline and refinery spills -- have been costly to both the oil industry and the public. For example, the estimated costs to Exxon of the Valdez tanker spill are on the order of $4 billion, including $2.8 billion (in 1993 dollars) for direct cleanup costs and $1.125 billion (in 1992 dollars) for settlement of damages claims caused by the spill. Application of contingent valuation costs and civil lawsuits pending in the State of Alaska could raise these costs appreciably. Even the costs of the much smaller 1991 oil spill at Texaco's refinery near Anacortes, Washington led to costs of $8 to 9 million. As a result, inexpensive waming, response and remediation technologies could lower oil spin costs, helping both the oil industry, the associated marine industries, and the environment. One means for reducing the impact and costs of oil spills is to undertake research and development on key aspects of the oil spill prevention, warming, and response and remediation systems. To target these funds to their best use, it is important to have sound data on the nature and size of spills, their likely occurrence and their unit costs. This information could then allow scarce R ampersand D dollars to be spent on areas and activities having the largest impact. This report is intended to provide the ''unit cost'' portion of this crucial information. The report examines the three key components of the US oil supply system, namely, tankers and barges; pipelines and refineries; and offshore production facilities. The specific purpose of the study was to establish the unit costs of oil spills. By manipulating this key information into a larger matrix that includes the size and frequency of occurrence of oil spills, it will be possible' to estimate the likely future impacts, costs, and sources of oil spills

    An urban survey of Lisbon, the largest city in Portugal, was carried out to investigate its environmental burden, emphasizing metallic elements and their public health impacts. This paper examines the geochemistry of lead (Pb) and its influence on human health data. A total of 51 soil samples were collected from urban recreational areas used by children to play outdoors. The semi-quantitative analysis of Pb was carried out by inductively coupled plasma mass spectrometry after an acid digestion. X-ray diffraction was used to characterize the soil mineralogy. The solid-phase distribution of Pb in the urban soils was investigated on a subset of 7 soils, out of a total of 51 samples, using a non-specific sequential extraction method coupled with chemometric analysis. Oral bioaccessibility measurements were obtained using the Unified BARGE Method developed by the Bioaccessibility Research Group of Europe. The objectives of the study are as follows: (1) investigation of Pb solid-phase distribution; (2) interpretation of Pb oral bioaccessibility measurements; (3) integration of metal geochemistry with human health data; and (4) understanding the influence of geochemistry and mineralogy on oral bioaccessibility. The results show that the bioaccessible fraction of Pb is lower when major metal fractions are associated with less soluble soil phases such as Fe oxyhydroxides, and more increased when the metal is in the highly soluble carbonate phase. However, there is some evidence that the proportion of carbonates in the soil environment is also a key control over the oral bioaccessibility of Pb, irrespective of its solid-phase fractionation.

  9. Afghanistan.

    1986-07-01

    This discussion of Afghanistan covers: the people, geography, history (European influence, reform and reaction, Daoud's Republic and the April 1978 coup, and the Soviet invasion), government and political conditions, the economy (agriculture, trade and industry, transportation, economic development), foreign relations, and relations between the US and Afghanistan. In 1985, the population was estimated to be 11 million (plus about 2.7 million refugees in Pakistan and 1 million refugees in Iran and the west). The annual growth rate is negative because of the war. In 1971 the UN estimate of infant mortality was 181.6/1000 live births with life expectancy 36.6 for men and 37.3 for women. Afghanistan's ethnically and linguistically mixed population reflects its location astride historic trade and invasion routes leading from central Asia into South and Southwest Asia. The dominant ethnic group, the Pukhtuns, make up about 40% of the population. Afghanistan has had a turbulent history. All of Afghanistan's rulers until the Marxist coup of 1978 were from Durani's tribe, and, since 1818, all were members of that tribe's Mohammadzai clan. Afghanistan is primarily an agricultural country, despite the fact that only 15% of its total land area is viable. This sector employs 3/4 of the working population and accounts for more than half of the gross domestic product. The Afghan economy remains tightly tied to that of the Soviet Union, its largest trading partner. Although Afghan has no railways or navigable rivers, the Amu Darya (Oxus) River on the Soviet-Afghan border does carry barge traffic. The Soviets pledged more than $300 million in new aid in 1984 and disbursed more than $400 million in commodities and new project aid. They signed a further agreement granting additional credits in February 1985. Since the December 1979 Soviet invasion, Afghanistan's foreign policy has mirrored that of the Soviet Union. The US has never recognized the Kabul regime and strongly opposes the

    This report was prepared in conjunction with the Basalt Waste Isolation Project in partial fulfillment of requirements to assess the effects of a deep geologic repository for radioactive wastes upon adjacent water resources within the Pasco Basin. Because of the many unanswered questions with respect to repository siting, environmental characterization, engineering design, and other factors related to the proposed facility, it is somewhat premature to present an intensive evaluation of such effects. However, it is considered appropriate at this time to speculate, in a generic fashion, upon the nature of these effects as a basis for future scenario evaluations. Accordingly, this report provides the following: (1) general information and data on the nature of water resources present within the Pasco Basin; (2) a description of present and, to the extent possible, a prediction of future use and trends; (3) speculation with respect to possible interfaces between the repository and adjacent water resources. Background information describes the setting of the Pasco Basin with respect to the physical and socioeconomic resources present. Uses of the water resource, with particular regard to industrial, agricultural, municipal, recreational, and river barging and transportation are described, and a matrix serves to show the existing administrative structure. For the groundwater system, three scenarios were evaluated briefly: importation and application of surface water for irrigation, excessive discharge from wells, and subsidence related to dewatering. In conclusion, it was determined that intrusion into the deeper groundwater systems within the Wanapum Basalt for well development is a foremost consideration with respect to scenarios involving contaminant release to the biosphere

    This paper describes the construction of a 10.8 km long NPS16 (406 mm, 16 inch diameter) pipeline, across Skaha Lake, in the south Okanagan valley, British Columbia, Canada. The water crossing is part of the 32 km South Okanagan Natural Gas Pipeline Project (SONG) operated by BC Gas. The pipeline is located in a region dependent on year-round tourism. Therefore, the design and construction was influenced by sensitive environmental and land use concerns. From earlier studies, BC Gas identified surface tow or lay as preferred installation methods. The contractor, Fraser River Pile and Dredge departed from a conventional laybarge methodology after evaluating environmental data and assessing locally available equipment. The contractor proposed a surface tow with multiple surface tie-ins. This approach modification to the ''Surface Tow and Buoy Release Method'' (STBRM) used previously with success on relatively short underwater pipelines. A total of 10 pipe strings, up to 1 km long, were towed into position on the lake and tied-in using a floating platform. The joined pipeline was lowered to the lakebed by divers releasing buoys while tension was maintained from a winch barge at the free end of the pipeline. From analysis and field verified measurement the installation stresses were well below the allowable limits during all phases of construction. The entire construction, including mobilization and demobilization, lasted less than three months, and actual pipelaying less than three weeks. Installation was completed within budget and on schedule, without any environmental or safety related incidents. The SONG pipeline became operational in December 1994

    This final report summarizes the work accomplished under the program entitled 'Study to Define Arctic Pollution Response Systems and Develop Arctic Oil Pollution Response Project Plans.' The objective of the program was to determine the most cost effective, environmentally compatible, and technically feasible Coast Guard arctic pollution response system that can be used in projected oil spill scenarios to recover and dispose of spilled oil. The optimum arctic pollution response system was determined by establishing the cost and effectiveness of response for sixteen oil spill response situations, and developing six alternative Coast Guard arctic pollution response systems based on these situations. These six systems were developed with a recognition of three distinctly different types of operational requirements, those for thick stable ice, dynamic hummocky ice, and open water or light ice conditions. The optimum system was then identified as the result of a cost effectiveness analysis. The six arctic oil spill scenarios consisted of a gathering pipeline rupture in the nearshore Beaufort Sea, an oil well blowout from a very large reservoir in the nearshore Chukchi Sea, crude oil tanker casualties in Norton Sound and in the Navarin Basin region of the Bering Sea, an oil well blowout from an average sized reservoir in Bristol Bay, and a fuel oil spill resulting from the collision of a fuel oil barge in Unimak Pass. The optimum system provides for a 25% response level for the Norton Sound, Navarin Basin, Bristol Bay, and Unimak Pass scenarios, and a 50% response level for the Beaufort Sea and Chukchi Sea scenarios.

    Full Text Available Iron-Cobalt catalyst is well known from both operational and economical aspects for Fischer-Tropsch synthesis. Effort to increase the efficiency of this kind of catalyst is an important research topic. In this work, the effect of lanthanum on characteristic behavior, conversion and selectivity of a Fe-Co/SiO2 Fischer-Tropsch catalyst was studied. The Fe-Co-La/SiO2 Catalysts were prepared using an incipient wetness impregnation method. These catalysts were then characterized by XRF-EDAX, BET and TPR techniques, and their performance were evaluated in a lab-scale reactor at 250ºC, H2/CO = 1.8 of molar ratio, 16 barg pressure and GHSV=600 h-1. TPR analysis showed that the addition of La lowered the reduction temperature of Fe-Co catalyst, and due to a lower temperature, the sintering of the catalyst can be mitigated. Furthermore, from the micro reactor tests (about 4 days, it was found that lanthanum promoted catalyst had higher selectivity toward hydrocarbons, and lower selectivity toward CO2.Received: 8th July 2013; Revised: 18th November 2013; Accepted: 1st December 2013[How to Cite: Abbasi, A., Ghasemi, M., Sadighi, S.

    Full Text Available Despite the fact that Robert Harley is known as Tory politician, he began his career as a Whig politician. His grandfather and father were Presbyterians, and Robert Harley himself was a Presbyterian during his entire life. Harley’s family supported the Glorious Revolution of 1688. In 1689 Robert Harley was first elected to the House of Commons as a representative of the Whig party. Thanks to his wife’s Foley family, Robert Harley was elected as a commissioner of public accounts in the House of Commons. In 1689 Britain entered the “war of King William” which was a burden for many gentry (Whigs or Tories. Robert Harley became famous in the parliament as a critic of the war and corruption in the army. In 1693 the Whig leaders headed the ministry and continued the war. Their policy divided the Whigs party in two factions: “Court Whigs” and “Country Whigs”. Robert Harley and his supporters became “Country Whigs”, and they criticized the “Court Whigs”. By 1700 Robert Harley joined the Tory party. The article also describes the evolution of historiography of Harley‘s policy. Victorian historians have called the Prime Minister a “stupid person”. The same opinion was repeated by Russian historians of the 19th century. But in the 20th century the assessment of Robert Harley’s activity was changed by the works of K. Feiling, G. Holmes, B.W. Hill and other historians. Soviet historians (for example M.A. Barg also called R.Harley a “mediocre politician”, but modern Russian historians (L.I. Ivonina, T.L. Labutina and others consider him a “clever statesman” and a “master of political intrigues and parliamentary diplomacy”.

    Bioaccessibility to assess potential risks resulting from exposure to Pb-contaminated soils is commonly estimated using various in vitro methods. However, existing in vitro methods yield different results depending on the composition of the extractant as well as the contaminated soils. For this reason, the relationships between the five commonly used in vitro methods, the Relative Bioavailability Leaching Procedure (RBALP), the unified BioAccessibility Research Group Europe (BARGE) method (UBM), the Solubility Bioaccessibility Research Consortium assay (SBRC), a Physiologically Based Extraction Test (PBET), and the in vitro Digestion Model (RIVM) were quantified statistically using 10 soils from long-term Pb-contaminated mining and smelter sites located in Western Australia and South Australia. For all 10 soils, the measured Pb bioaccessibility regarding all in vitro methods varied from 1.9 to 106% for gastric phase, which is higher than that for intestinal phase: 0.2 ∼ 78.6%. The variations in Pb bioaccessibility depend on the in vitro models being used, suggesting that the method chosen for bioaccessibility assessment must be validated against in vivo studies prior to use for predicting risk. Regression studies between RBALP and SRBC, RBALP and RIVM (0.06) (0.06 g of soil in each tube, S:L ratios for gastric phase and intestinal phase are 1:375 and 1:958, respectively) showed that Pb bioaccessibility based on the three methods were comparable. Meanwhile, the slopes between RBALP and UBM, RBALP and RIVM (0.6) (0.6 g soil in each tube, S:L ratios for gastric phase and intestinal phase are 1:37.5 and 1:96, respectively) were 1.21 and 1.02, respectively. The findings presented in this study could help standardize in vitro bioaccessibility measurements and provide a scientific basis for further relating Pb bioavailability and soil properties.

    This paper presents the use of the IWA ADM1 to predict and interpret results from two full-scale anaerobic digesters fed with thermal hyrolysate (waste activated sludge with a long upstream sludge age) from a Cambi hydrolysis process operating at 165°C and 6 bar-g. The first digester was fed conventionally-though intermittently, while the second was heavily diluted through a substantial component of the evaluation period (110 days). There were a number of important outcomes-related to both model application, and model predictions. Input and inert COD: mass ratio was very important, and was considerably higher than the 1.42 g g⁻¹ used for biomass throughout the IWA activated sludge and anaerobic digestion models. Input COD: VS ratio was 1.6 g g⁻¹, and inert COD: VS ratio was 1.7 g g⁻¹. The model succeeded on a number of levels, including effective prediction of important outputs (degradability, gas flow and composition, and final solids), clarification of the substantial data scatter, prediction of recovery times during operationally poor periods, and cross-validation of the results between digester 1 and digester 2. Key failures in model performance were related to an early incorrect assumption of the COD: VS ratio of 1.42 g g⁻¹, and intermittent high acetate levels, most likely caused by inhibition, and rapid acclimatisation to ammonia. The acute free ammonia limit was found to be 0.008 M NH(3)-N, while the chronic inhibition constant (K(I,NH₃,ac)) was 0.007 ± 0.001 M NH₃-N. Overall, this is a complex system, and application of the model added significant confidence to the initial operational decisions during an aggressive startup on an atypical feed.

    Mineral carbonation of serpentinite mining residue offers an environmentally secure and permanent storage of carbon dioxide. The strategy of using readily available mining residue for the direct treatment of flue gas could improve the energy demand and economics of CO2 sequestration by avoiding the mineral extraction and separate CO2 capture steps. The present is a laboratory scale study to assess the possibility of CO2 fixation in serpentinite mining residues via direct gas-solid reaction. The degree of carbonation is measured both in the absence and presence of water vapor in a batch reactor. The gas used is a simulated gas mixture reproducing an average cement flue gas CO2 composition of 18 vol.% CO2. The reaction parameters considered are temperature, total gas pressure, time, and concentration of water vapor. In the absence of water vapor, the gas-solid carbonation of serpentinite mining residues is negligible, but the residues removed CO2 from the feed gas possibly due to reversible adsorption. The presence of small amount of water vapor enhances the gas-solid carbonation, but the measured rates are too low for practical application. The maximum CO2 fixation obtained is 0.07 g CO2 when reacting 1 g of residue at 200 °C and 25 barg (pCO2 ≈ 4.7) in a gas mixture containing 18 vol.% CO2 and 10 vol.% water vapor in 1 h. The fixation is likely surface limited and restricted due to poor gas-solid interaction. It was identified that both the relative humidity and carbon dioxide-water vapor ratio have a role in CO2 fixation regardless of the percentage of water vapor.

    India has made remarkable progress in creating a modern and diversified industrial base, since its independence. Most of the refineries, petrochemical and fertilizer industries are located in the coastal zone and catered by 12 major ports along the 7500 km length of Indian coastline. Since, transportation of crude oil and POL products from ports to refineries are mostly by pipelines, rail/ road, besides some quantity by barge/ ships along the coast, there will be chances of oil spill/leakage. Managing these events before and during their occurrence is imperative to the protection of people and natural resources. The present study was carried out with a view to develop Terrestrial Chemical Spill Information System [TCSIS], using Remote Sensing [RS], GIS and VB 6.0., for the Mangalore coastal zone industrial area of Dakshina Kannada district, Karnataka state, along West Coast of India. The study area lies between 74°45'00'' to 74°52'30''E longitude and 12°52'30'' to 13°00'00''N latitude. The database of TCSIS consists of both conventional data and RS data, and analysed using ERDAS Imagine 9.0 and ArcGIS 8.3 software. Different thematic maps prepared include LU/LC map, drainage map, road and pipeline network map, slope map, Digital Elevation Model, relative risk maps and pipeline route for the transportation of hazardous chemicals from port to refinery. The TCSIS module developed using RS, GIS and V.B.6.0, characterizes the ability of a spilled chemical to immediately impact human health, natural resources, and incorporates these into an overall measure of terrestrial chemical risk and aids in planning, preventing and responding to a terrestrial chemical spill.

    This paper addressed the geotechnical aspects of the deployment of the steel drilling caisson (SDC) at the Paktoa site in the Canadian Beaufort Sea. The SDC is a bottom founded mobile offshore drilling platform that can operate in 8 to 25 m of water in an Arctic environment. It is mated to a submersible barge in order to resist large ice forces on the structure at sites with relatively weak soils, without the need for site preparation. To date, the SDC has been deployed at 8 sites in the Canadian and Alaskan Beaufort Sea. This paper focused on the Paktoa location, where the SDC was deployed 50 km offshore in a water depth of 14 m during the winter of 2005-2006. Geotechnical investigations were conducted from the landfast ice prior to deployment and from the SDC deck. This paper described the soil properties and design loading; design stability; and deformation analysis. The environmental loads considered for the SDC design included ice push, waves and earthquakes. The ice loading was the dominant loading case. The instrumentation installed in the seabed included 2 push-in piezometers and an inclinometer. An ice loading event in February 2006 resulted in considerable displacements in the in-place inclinometer string below the SDC. Several analysis methods were used to estimate the magnitude of the ice load during this event in order to better understand the magnitude of ice loading for future Arctic deployments of gravity based drilling platforms. It was concluded that further deployments should have a minimum of 2 and preferably 4 in-place inclinometer strings to measure real-time deformation of the seabed to enable measurement of rotation of the structure that may occur due to asymmetrical ice loading. 10 refs., 2 tabs., 15 figs.
