TRB Special Report 306: Naval Engineering in the 21st Century: The Science and Technology Foundation for Future Naval Fleets examines the state of basic and applied research in the scientific fields that support naval engineering and explores whether Office of Naval Research (ONR) activities, under its National Naval Responsibility for Naval Engineering (NNR-NE) initiative, have been effective in sustaining these fields.

Environmental engineers support the well-being of people and the planet in areas where the two intersect. Over the decades the field has improved countless lives through innovative systems for delivering water, treating waste, and preventing and remediating pollution in air, water, and soil. These achievements are a testament to the multidisciplinary, pragmatic, systems-oriented approach that characterizes environmental engineering. Environmental Engineering for the 21st Century: Addressing Grand Challenges outlines the crucial role for environmental engineers in this period of dramatic growth and change. The report identifies five pressing challenges of the 21st century that environmental engineers are uniquely poised to help advance: sustainably supply food, water, and energy; curb climate change and adapt to its impacts; design a future without pollution and waste; create efficient, healthy, resilient cities; and foster informed decisions and actions.

Marine transportation is considered as an integral part of the global economy as more than 90 per cent of global trade goods are carried through the sea. The shipping industry underwent a tremendous growth during the last century (from 2.6 billion tons annual shipments in 1970 to 9.2 billion tons annual shipments in 2012). The International Maritime Organization (IMO) has been vigorously seeking for new measures for further improvements in energy efficiency and emissions reduction, and swift implementation of these measures to reduce the harmful emissions from international shipping. Chapter One provides the basic formulation of a coupled finite element of interface. It is followed by two examples of applications related to the vertical (uplift) or lateral loading of a suction caisson. In Chapter Two, the authors try to introduce some examples of propulsion layouts related to their previous experience introducing simplified criteria for a global design of the propulsion layout. This is achieved by melting mechatronics, fluid dynamics and more generally miscellaneous engineering topics that are often deeply studied by different working teams with different competences. In Chapter Three, a comprehensive overview of green ship technologies is presented which includes basic concepts, principles and potential, related core issues and possible solutions.

TRB Special Report 306: Naval Engineering in the 21st Century: The Science and Technology Foundation for Future Naval Fleets examines the state of basic and applied research in the scientific fields that support naval engineering and explores whether Office of Naval Research (ONR) activities, under its National Naval Responsibility for Naval Engineering (NNR-NE) initiative, have been effective in sustaining these fields. The committee developed a series of conclusions and recommendations in five areas--the value of the NNR-NE, the state of science and technology supporting naval engineering, the wholeness of the NNR-NE research portfolio, opportunities for enhancement of research and education, and the effectiveness of the NNR-NE initiative. The report's recommendations are addressed to the administrators of the NNR-NE initiative and of ONR.
