Are the nation's ports adequate for our present and future needs? This volume points out that no significant new deep-water construction has occurred for a decade, and provides the information and analysis needed to goad the ports and the federal government into action. The book asks three questions: Is additional port construction and maintenance dredging needed now or over the next 20 years? What would prevent dredging if it is needed? What alternatives could make additional dredging possible? The book identifies several problems in dredging ports, including the long interval between a decision to deepen a port and the time the alterations are complete. The United States needs to speed port construction to meet changing needs, and the committee recommends that we prepare for future needs by dredging now.

Over the last 100 years, sea level has risen approximately 12 centimeters and is expected to continue rising at an even faster rate. This situation has serious implications for human activity along our coasts. In this book, geological and coastal engineering experts examine recent sea level trends and project changes over the next 100 years, anticipating shoreline response to changing sea level and the consequences for coastal development and uses. Scenarios for future sea level rise and several case studies are presented.

While major oil spills are rare, oil slicks can have disastrous environmental and economic consequences. Based on laboratory and field research, as well as on actual case histories, this book summarizes research on the use of chemical dispersants: their effectiveness and limitations, and the results of using them in different spill situations.

Much of the U.S. coastline is rapidly changing--mostly eroding. That fact places increasing pressure on the planners and managers responsible for coastal development and protection, and could have a direct effect on many of the 125 million Americans living within 50 miles of the coast who rely on its resources and beaches for their livelihood or recreation. Although rapid advances have been made in the measurement systems needed to understand and describe the forces and changes at work in the surf-zone environment, their potential for allowing more accurate and reliable planning and engineering responses has not been fully realized. This book assesses coastal data needs, instrumentation, and analyses, and recommends areas in which more information or better instrumentation is needed.

Can we design an oil tanker that meets our complex demands for environmental protection, economical operation, and crew safety? This volume evaluates and ranks a wide variety of tank ship hull designs proposed by experts around the world. Based on extensive research and studies, the book explores the implications of our rising demand for petroleum and increase in tanker operations; U.S. government regulations and U.S. Coast Guard policies regarding designs for new tank vessel construction; how new ship design would affect crew safety, maintenance, inspection, and other technical issues; the prospects for retrofitting existing tankers to reduce the risk of oil spills; and more. The conclusions and recommendations will be particularly important to maritime safety regulators in the United States and abroad; naval architects; ship operators and engineers; and officials in the petroleum, shipping, and marine insurance industries.

Marine debris is a serious environmental problem. To do its part, the United States has agreed to abide by the international treaty for garbage control at sea, known as MARPOL 73/78 Annex V. Clean Ships, Clean Ports, Clean Oceans explores the challenge of translating Annex V into workable laws and regulations for all kinds of ships and boats, from cruise ships to fishing crafts and recreational boats. The volume examines how existing resources can be leveraged into a comprehensive strategy for compliance, including integrated waste management systems and effective enforcement. Clean Ships, Clean Ports, Clean Oceans describes both progress toward and obstacles to Annex V compliance. The book covers * How shipborne garbage orignates and what happens to garbage discharged into the seas. * Effects of discharge on human health, wildlife safety, and aesthetics. * Differences in perspective among military, industrial, and recreational seafarers and shoreside facilities. Clean Ships, Clean Ports, Clean Oceans will be important to marine policymakers, port administrators, ship operations officers, maritime engineers, and marine ecologists.

The European zebra mussel in the Great Lakes, a toxic Japanese dinoflagellate transferred to Australia--such biologically and economically harmful stowaways have made it imperative to achieve better management of ballast water in ocean-going vessels. Stemming the Tide examines the introduction of nonindigenous species through ballast water discharge. Ballast is any solid or liquid that is taken aboard ship to achieve more controlled and safer operation. This expert volume * Assesses current national and international approaches to the problem and makes recommendations for U.S. government agencies, the U.S. maritime industry, and the member states of the International Maritime Organization. * Appraises technologies for controlling the transfer of organisms--biocides, filtration, heat treatment, and others --with a view toward developing the most promising methods for shipboard demonstration. * Evaluates methods for monitoring the effectiveness of ballast water management in removing unwanted organisms. The book addresses the constraints inherent in ballast water management, notably shipboard ballast treatment and monitoring.Also, the committee outlines efforts to set an acceptable level of risk for species introduction using the techniques of risk analysis. Stemming the Tide will be important to all stakeholders in the issue of unwanted species introduction through ballast discharge: policymakers, port authorities, shippers, ship operators, suppliers to the maritime industry, marine biologists, marine engineers, and environmentalists.

The safety record of lightering (the transfer of petroleum cargo at sea from a large tanker to smaller ones) has been excellent in U.S. waters in recent years, as evidenced by the very low rate of spillage of oil both in absolute terms and compared with all other tanker-related accidental spills. The lightering safety record is likely to be maintained or even improved in the future as overall quality improvements in the shipping industry are implemented. Risks can be reduced even further through measures that enhance sound lightering standards and practices, support cooperative industry efforts to maintain safety, and increase the availability of essential information to shipping companies and mariners. Only continued vigilance and attention to safety initiatives can avert serious accidents involving tankers carrying large volumes of oil.

The future safety of maritime transportation in the United States-a major factor in the nation's international trade and economic well-being-will depend heavily on the quality of port and waterways information systems. Many U.S. ports and waterways lack adequate information services, although certain elements of advanced systems are now available in some locations. Barriers to improvements in information systems include the division of responsibilities for waterways management among multiple agencies at all levels of government, a lack of coordination among the federal agencies responsible for waterways management, inadequate budgets for some critical maritime programs, the high costs of some specialized technologies, stakeholder opposition to user fees, limited access to certain key data, the incompatibility of many independently developed systems, and the absence of standards for some attractive technologies.In this report, the second phase of a three-year study by the Committee on Maritime Advanced Information Systems of the National Research Council, a strategy is presented for overcoming the major barriers and deficiencies and providing a minimum level of maritime safety information nationwide. In this phase of the study, the committee concentrated on maritime information systems that promote safety, which is the area of greatest need. The committee did not examine in detail the relationship between navigation safety and maritime transportation efficiency or evaluate information systems that promote efficiency; the committee believes, however, that these issues deserve further attention.

In the Coast Guard Authorization Act of 1996, the United States Coast Guard (USCG) was directed to assess the risk of spills for oils that may sink or be negatively buoyant, to examine and evaluate existing cleanup technologies, and to identify and appraise technological and financial barriers that could impede a prompt response to such spills. The USCG requested that the National Research Council (NRC) perform these tasks. In response to this request, the NRC established the Committee on the Marine Transportation of Heavy Oils.

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 ofa "and more effective measures againsta "pollutant discharge. The book discusses: * Inputa "where the discharges come from, including the role of two-stroke engines used on recreational craft. * Behavior or fatea "how oil is affected by processes such as evaporation as it moves through the marine environment. * Effectsa "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.

Large ships transporting hazardous cargoes, notorious marine accidents, and damage to marine ecosystems from tanker spills have heightened public concern for the safe navigation of ships.

It addresses the application of new technology to reduce the probability of accidents, controversies over the effectiveness of waterways management and marine pilotage, and navigational decisionmaking. The book also explores the way pilots of ships and tugs are trained, licensed, and held accountable. Minding the Helm approaches navigational safety from the perspectives of risk assessment and the integration of human, technological, and organizational systems. Air and marine traffic regulation methods are compared, including the use of vessel traffic services. With a store of current information and examples, this document will be indispensable to federal and state pilotage and licensing authorities and marine traffic regulators, the Coast Guard, pilot associations, and the shipping and towing industries.It will also interest individuals involved in waterway design, marine education, and the marine environment.

The blowout of the Macondo well on April 20, 2010, led to enormous consequences for the individuals involved in the drilling operations, and for their families. Eleven workers on the Deepwater Horizon drilling rig lost their lives and 16 others were seriously injured. There were also enormous consequences for the companies involved in the drilling operations, to the Gulf of Mexico environment, and to the economy of the region and beyond. The flow continued for nearly 3 months before the well could be completely killed, during which time, nearly 5 million barrels of oil spilled into the gulf. Macondo Well-Deepwater Horizon Blowout examines the causes of the blowout and provides a series of recommendations, for both the oil and gas industry and government regulators, intended to reduce the likelihood and impact of any future losses of well control during offshore drilling.According to this report, companies involved in offshore drilling should take a "system safety" approach to anticipating and managing possible dangers at every level of operation -- from ensuring the integrity of wells to designing blowout preventers that function under all foreseeable conditions-- in order to reduce the risk of another accident as catastrophic as the Deepwater Horizon explosion and oil spill. In addition, an enhanced regulatory approach should combine strong industry safety goals with mandatory oversight at critical points during drilling operations. Macondo Well-Deepwater Horizon Blowout discusses ultimate responsibility and accountability for well integrity and safety of offshore equipment, formal system safety education and training of personnel engaged in offshore drilling, and guidelines that should be established so that well designs incorporate protection against the various credible risks associated with the drilling and abandonment process.This book will be of interest to professionals in the oil and gas industry, government decision makers, environmental advocacy groups, and others who seek an understanding of the processes involved in order to ensure safety in undertakings of this nature.

Best Available and Safest Technologies for Offshore Oil and Gas Operations: Options for Implementation explores a range of options for improving the implementation of the U.S. Department of the Interior's congressional mandate to require the use of best available and safety technologies in offshore oil and gas operations. In the Outer Continental Shelf Lands Act, Congress directs the Secretary of the Interior to regulate oil and gas operations in federal waters. The act mandates that the Secretary "shall require, on all new drilling and production operations and, wherever practicable, on existing operations, the use of the best available and safest technologies which the Secretary determines to be economically feasible, wherever failure of equipment would have a significant effect on safety, health, or the environment, except where the Secretary determines that the incremental benefits are clearly insufficient to justify the incremental costs of utilizing such technologies."This report, which was requested by Department of the Interior's Bureau of Safety and Environmental Enforcement (BSEE), also reviews options and issues that BSEE is already considering to improve implementation of the best available and safest technologies requirement.
