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.

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.

Download or read book Oil Spill Dispersants written by Clayton/Payne and published by CRC Press. This book was released on 2020-08-26 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil Spill Dispersants: Mechanisms of Action and Laboratory Tests provides a comprehensive summary of current information available regarding the general formulation of commercial dispersants and their function to lower oil-water interfacial tension. The book considers how chemical dispersants work for oil spills, the properties and chemistry of oils (including weathering state), the variables that affect dispersant performance, and the relationships between laboratory methods and field situations. The book also considers the strengths and limitations of specific laboratory tests, including brief discussions of the applicability of results for estimating dispersant performance in field trials or conditions encountered during real spill events. Laboratory tests are separated into four groups: tank tests, shake/flask tests, interfacial surface tension tests, and flume tests. Rapid-screen field tests are considered as a separate group. Recommendations for improvements in future laboratory testing are offered as well. Oil Spill Dispersants will be useful for regulators evaluating dispersant agents, field personnel involved with using dispersants, laboratory scientists studying performance and behavior of oil and dispersants, and managers responsible for designing studies related to the treatment of oil slicks with dispersants.
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.

This book was released on 2013-12-20 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the Gulf of Mexico recovers from the Deepwater Horizon oil spill, natural resource managers face the challenge of understanding the impacts of the spill and setting priorities for restoration work. The full value of losses resulting from the spill cannot be captured, however, without consideration of changes in ecosystem services-the benefits delivered to society through natural processes. An Ecosystem Services Approach to Assessing the Impacts of the Deepwater Horizon Oil Spill in the Gulf of Mexico discusses the benefits and challenges associated with using an ecosystem services approach to damage assessment, describing potential impacts of response technologies, exploring the role of resilience, and offering suggestions for areas of future research. This report illustrates how this approach might be applied to coastal wetlands, fisheries, marine mammals, and the deep sea-each of which provide key ecosystem services in the Gulf-and identifies substantial differences among these case studies. The report also discusses the suite of technologies used in the spill response, including burning, skimming, and chemical dispersants, and their possible long-term impacts on ecosystem services.
Download or read book Deep Oil Spills written by Steven A. Murawski and published by Springer. This book was released on 2019-06-29 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for oil and gas has brought exploration and production to unprecedented depths of the world’s oceans. Currently, over 50% of the oil from the Gulf of Mexico now comes from waters in excess of 1,500 meters (one mile) deep, where no oil was produced just 20 years ago. The Deepwater Horizon oil spill blowout did much to change the perception of oil spills as coming just from tanker accidents, train derailments, and pipeline ruptures. In fact, beginning with the Ixtoc 1 spill off Campeche, Mexico in 1979-1980, there have been a series of large spill events originating at the sea bottom and creating a myriad of new environmental and well control challenges. This volume explores the physics, chemistry, sub-surface oil deposition and environmental impacts of deep oil spills. Key lessons learned from the responses to previous deep spills, as well as unresolved scientific questions for additional research are highlighted, all of which are appropriate for governmental regulators, politicians, industry decision-makers, first responders, researchers and students wanting an incisive overview of issues surrounding deep-water oil and gas production.

This book was released on 2010-09-01 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the origin of the leak, to the amount of oil released into the environment, to the spill's duration, the 2010 Gulf of Mexico oil spill poses unique challenges to human health. The risks associated with extensive, prolonged use of dispersants, with oil fumes, and with particulate matter from controlled burns are also uncertain. There have been concerns about the extent to which hazards, such as physical and chemical exposures and social and economic disruptions, will impact the overall health of people who live and work near the area of the oil spill. Although studies of previous oil spills provide some basis for identifying and mitigating the human health effects of these exposures, the existing data are insufficient to fully understand and predict the overall impact of hazards from the Deepwater Horizon oil spill on the health of workers, volunteers, residents, visitors, and special populations. Assessing the Effects of the Gulf of Mexico Oil Spill on Human Health identifies populations at increased risks for adverse health effects and explores effective communication strategies to convey health information to these at-risk populations. The book also discusses the need for appropriate surveillance systems to monitor the spill's potential short- and long-term health effects on affected communities and individuals. Assessing the Effects of the Gulf of Mexico Oil Spill on Human Health is a useful resource that can help policy makers, public health officials, academics, community advocates, scientists, and members of the public collaborate to create a monitoring and surveillance system that results in "actionable" information and that identifies emerging health risks in specific populations.

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.

This book was released on 2010-12-28 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: EMERGENCY RESPONSE MANAGEMENT OF OFFSHORE Examines the Deepwater Horizon disaster and offers processes for safety and environmental protection Though renewable energy is a growing piece of the energy “pie,” fossil fuels still dominate our energy supplies and will continue to do so for decades. This makes offshore drilling, especially in places like the Gulf of Mexico and North Sea, extremely important for the future of the world’s energy supply. Unfortunately, the world has been witnessing, over and over again, accidents, deadly explosions, spills, and environmental disasters that could have been avoided with proper safety and environmental processes put in place. The Deepwater Horizon catastrophe is the largest offshore oil spill in U.S. history and an ecological nightmare of epic proportions. Emergency Response Management of Offshore Oil Spills aids in the response of this and future disasters by providing this handy reference volume for engineers, managers, and other emergency responders. This timely publication outlines the toxic nature of crude oil, covering properties of crude oil, chemical composition, toxicity to humans and marine life, and investigates the impact of oil spills from historical case studies. The current arsenals available to address oil spills, such as dispersants, absorbing booms, skimming, and other methods, are also discussed. Technologies that are rapidly being developed to address the Gulf Oil Spill are considered, along with extensive information on chemical protective clothing, air monitoring, respiratory protection, management of waste, and much more. The book concludes with a chapter discussing responsible care and takes a critical look at the reasons why the Deepwater Horizon rig catastrophe happened and examines the follow-up that ensued after the incident. Emergency Response Management of Offshore Oil Spills provides: Examples of 26 major oil spills ranked from largest to smallest, describing each incident and the amount of oil spilled Recommendations and guidance on proper air monitoring methods Suggestions related to protective garments such as respirators Comparative product information on chemical dispersants, shoreline bleaching and cleaning chemicals Detailed toxicity data for humans and marine life Discussions in the areas of deficiencies in responding to spills and why the oil industry needs to be more responsive to developing technologies Hazardous materials protocols, including OSHA- and EPA- recommended safe work practices for dealing with hazardous materials

This book was released on 2016-03-22 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diluted bitumen has been transported by pipeline in the United States for more than 40 years, with the amount increasing recently as a result of improved extraction technologies and resulting increases in production and exportation of Canadian diluted bitumen. The increased importation of Canadian diluted bitumen to the United States has strained the existing pipeline capacity and contributed to the expansion of pipeline mileage over the past 5 years. Although rising North American crude oil production has resulted in greater transport of crude oil by rail or tanker, oil pipelines continue to deliver the vast majority of crude oil supplies to U.S. refineries. Spills of Diluted Bitumen from Pipelines examines the current state of knowledge and identifies the relevant properties and characteristics of the transport, fate, and effects of diluted bitumen and commonly transported crude oils when spilled in the environment. This report assesses whether the differences between properties of diluted bitumen and those of other commonly transported crude oils warrant modifications to the regulations governing spill response plans and cleanup. Given the nature of pipeline operations, response planning, and the oil industry, the recommendations outlined in this study are broadly applicable to other modes of transportation as well.
