Available in PDF, EPUB and Kindle. Book excerpt: Increasing production and transportation of oil has increased the risk of oil spills. The transport and fate of spilled oil are important factors to consider in oil spill response. However, challenges remain in the observation and analysis of these factors, especially during the short initial period that is critical for response. The challenges result from the complexity and uncertainty of oil properties and the environmental conditions, as well as their interactions. Oil spill models have become important tools in facilitating oil spill response. Over recent decades, more than 50 oil spill models have been developed, yet limitations still exist including: (1) natural dispersion algorithms are mainly based on empirical equations with insufficient theoretical support; and (2) oil biodegradation algorithms must represent the complexity of this process with limited knowledge and information. In order to help fill the existing gaps, this study develops (1) a dispersion model based on the modified Weber number scaling approach of Stiftelsen for industriell og teknisk forskning (SINTEF); and (2) a new biodegradation model based on the coupling of pseudo-component and exponential decay biodegradation algorithms. The newly developed models are incorporated into the Modelo Hidrodinâmico (MOHID) model. It is shown that the newly developed dispersion and biodegradation algorithms extend the capability of MOHID.

Download or read book Responding to Oil Spills in the U S Arctic Marine Environment written by National Research Council and published by National Academies Press. This book was released on 2014-08-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
Download or read book A Comparison of Oil Weathering Model Equations and Application to Douglas Channel written by Augustine Van der Baaren and published by . This book was released on 2018 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of this work was to develop software tools to provide a basis for understanding commonly used oil weathering models. We evaluated computational algorithms that are used by three popular oil weathering models, and similar algorithms that are used by other researchers, to see how sensitive the algorithms/models were to variable environmental conditions and to gather information on whether the models typically produce similar results. We computed the weathering evolution, under constant and variable environmental conditions, of dispersion, release/spreading, evaporation, emulsification (water content), oil density, and oil viscosity for a hypothetical spill, and we compared the results for the different models' algorithms. We applied the algorithms to a second hypothetical spill. The second spill was of Cold Lake Bitumen in Douglas Channel. We found that none of the algorithms produced realistic results when using a time varying wind speed as input probably because they were developed under conditions of constant wind speeds. Finally, this work is not a definitive description of the expected evolution of the properties of diluted bitumen in Douglas Channel"--Abstract, p. xi.

Download or read book Oil Spill Dispersants written by Committee on Understanding Oil Spill Dispersants: Efficacy and Effects and published by . This book was released on 2005 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 3 million gallons of oil or refined petroleum products are spilled into U.S. waters every year. Oil dispersants (chemical agents such as surfactants, solvents, and other compounds) are used to reduce the effect of oil spills by changing the chemical and physical properties of the oil. By enhancing the amount of oil that physically mixes into the water, dispersants can reduce the potential that a surface slick will contaminate shoreline habitats. Although called for in the Oil Pollution Act of 1990 as a tool for minimizing the impact of oil spills, the use of chemical dispersants has long been controversial. This book reviews the adequacy of existing information and ongoing research regarding the effectiveness of dispersants as an oil spill response technique, as well as the effect of dispersed oil on marine and coastal ecosystems. Oil Spill Dispersants also includes recommended steps for policy makers faced with making hard choices regarding the use of dispersants as part of spill contingency planning efforts or during actual spills.
Download or read book Scenarios and Responses to Future Deep Oil Spills written by Steven A. Murawski and published by Springer. This book was released on 2019-07-04 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has often been said that generals prepare for the next war by re-fighting the last. The Deepwater Horizon (DWH) oil spill was unlike any previous – an underwater well blowout 1,500 meters deep. Much has been learned in the wake of DWH and these lessons should in turn be applied to both similar oil spill scenarios and those arising from “frontier” explorations by the marine oil industry. The next deep oil well blowout may be at 3,000 meters or even deeper. This volume summarizes regional (Gulf of Mexico) and global megatrends in marine oil exploration and production. Research in a number of key areas including the behavior of oil and gas under extreme pressure, impacts on biological resources of the deep sea, and the fate of oil and gas released in spills is synthesized. A number of deep oil spills are simulated with detailed computer models, and the likely effects of the spills and potential mitigation measures used to combat them are compared. Recommended changes in policies governing marine oil exploration and development are proposed, as well as additional research to close critical and emerging knowledge gaps. This volume synthesizes state-of-the-art research in deep oil spill behavior and response. It is thus relevant for government and industry oil spill responders, policy formulators and implementers, and academics and students desiring an in-depth and balanced overview of key issues and uncertainties surrounding the quest for deep oil and potential impacts on the environment.

Download or read book A Review of Genwest s Final Report on Effective Daily Recovery Capacity EDRC written by National Research Council and published by National Academies Press. This book was released on 2013-11-27 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bureau of Safety and Environmental Enforcement (BSEE) enforces compliance with oil spill response requirements for facilities located seaward of the coast line. It commissioned Genwest Systems, Inc., to assess the existing planning standard for response to offshore oil spills with mechanical oil skimming systems, known as the Effective Daily Recovery Capacity (EDRC), and to consider improvements to that standard. In its report, Genwest proposed an Estimated Recovery System Potential (ERSP) calculation as an alternative to EDRC. BSEE specifically asked the National Research Council committee to consider three aspects of the ERSP approach in the Genwest report: the proposed methodology of ERSP, its applicability, and the computer model behind ERSP. A Review of Genwest Effective Daily Recovery Capacity (EDRC) Project Final Report is an objective technical evaluation of the report produced by Genwest Systems, Inc., on the Effective Daily Recovery Capacity (EDRC). This report evaluates the scientific basis of the methodology, applicability, and modeling approach used in the Genwest report. In response to its statement of task, the authoring committee found the new approach for estimating the efficiency of oil skimmers presented by Genwest, (ERSP), to be basically sound and a substantial improvement over methods currently employed by BSEE in its rule-making. However, there are a number of simple improvements that can and should be made to the ERSP approach that would be extremely useful. This report examines the methodology and applicability of the ERSP calculation and discusses Genwests's computer model.
Download or read book The Use of Dispersants in Marine Oil Spill Response written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-04-24 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether the result of an oil well blowout, vessel collision or grounding, leaking pipeline, or other incident at sea, each marine oil spill will present unique circumstances and challenges. The oil type and properties, location, time of year, duration of spill, water depth, environmental conditions, affected biomes, potential human community impact, and available resources may vary significantly. Also, each spill may be governed by policy guidelines, such as those set forth in the National Response Plan, Regional Response Plans, or Area Contingency Plans. To respond effectively to the specific conditions presented during an oil spill, spill responders have used a variety of response optionsâ€"including mechanical recovery of oil using skimmers and booms, in situ burning of oil, monitored natural attenuation of oil, and dispersion of oil by chemical dispersants. Because each response method has advantages and disadvantages, it is important to understand specific scenarios where a net benefit may be achieved by using a particular tool or combination of tools. This report builds on two previous National Research Council reports on dispersant use to provide a current understanding of the state of science and to inform future marine oil spill response operations. The response to the 2010 Deepwater Horizon spill included an unprecedented use of dispersants via both surface application and subsea injection. The magnitude of the spill stimulated interest and funding for research on oil spill response, and dispersant use in particular. This study assesses the effects and efficacy of dispersants as an oil spill response tool and evaluates trade-offs associated with dispersant use.
