This book presents an analytical review of the world’s construction of icebreakers, detailing the prospects of navigation along the North Sea Route. It provides the results of engineering and cost efficiency feasibility studies (ECSs) for arctic icebreakers and ice-going new generation transport ships forming part of the Russian merchant fleet. The book considers theoretical and experimental studies of ice performance of domestic icebreakers, provides the results of research into the design and construction of ice navigation transport ships, and discusses aspects of safe navigation in ice conditions.

The United States has enduring national and strategic interests in the polar regions, including citizens living above the Arctic circle and three year-round scientific stations in the Antarctic. Polar icebreaking ships are needed to access both regions. Over the past several decades, the U.S. government has supported a fleet of four icebreakersâ€"three multi-mission U.S. Coast Guard ships (the POLAR SEA, POLAR STAR, and HEALY) and the National Science Foundation's PALMER, which is dedicated solely to scientific research. Today, the POLAR STAR and the POLAR SEA are at the end of their service lives, and a lack of funds and no plans for an extension of the program has put U.S. icebreaking capability at risk. This report concludes that the United States should continue to support its interests in the Arctic and Antarctic for multiple missions, including maintaining leadership in polar science. The report recommends that the United States immediately program, budget, design, and construct two new polar icebreakers to be operated by the U.S. Coast Guard. The POLAR SEA should remain mission capable and the POLAR STAR should remain available for reactivation until the new polar icebreakers enter service. The U.S. Coast Guard should be provided sufficient operations and maintenance budget to support an increased, regular, and influential presence in the Arctic, with support from other agencies. The report also calls for a Presidential Decision Directive to clearly align agency responsibilities and budgetary authorities.

Marine Rudders and Control Surfaces guides naval architects from the first principles of the physics of control surface operation, to the use of experimental and empirical data and applied computational fluid dynamic modelling of rudders and control surfaces.The empirical and theoretical methods applied to control surface design are described in depth and their use explained through application to particular cases. The design procedures are complemented with a number of worked practical examples of rudder and control surface design.• The only text dedicated to marine control surface design• Provides experimental, theoretical and applied design information valuable for practising engineers, designers and students• Accompanied by an online extensive experimental database together with software for theoreticalpredictions and design development

This book provides a thorough introduction to the formal foundations and practical applications of Bayesian networks. It provides an extensive discussion of techniques for building Bayesian networks that model real-world situations, including techniques for synthesizing models from design, learning models from data, and debugging models using sensitivity analysis. It also treats exact and approximate inference algorithms at both theoretical and practical levels. The author assumes very little background on the covered subjects, supplying in-depth discussions for theoretically inclined readers and enough practical details to provide an algorithmic cookbook for the system developer.

This volume brings together multiple perspectives on both the changing Arctic environment and the challenges and opportunities it presents for the shipping sector. It argues for the adoption of a forward-looking agenda that respects the fragile and changing Arctic frontier. With the accelerated interest in and potential for new maritime trade routes, commercial transportation and natural resource development, the pressures on the changing Arctic marine environment will only increase. The International Maritime Organization Polar Code is an important step toward Arctic stewardship. This new volume serves as an important guide to this rapidly developing agenda. Addressing a range of aspects, it offers a valuable resource for academics, practitioners, environmentalists and affected authorities in the shipping industry alike.
