Book excerpt: 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.

This book was released on 2006-01-08 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The age and condition of the U.S. Coast Guard's polar icebreakers are jeopardizing national security and scientific research in the Arctic and Antarctic, according to an interim report from the National Academies. Because of a shortfall in funding for U.S. polar icebreaking activities, long-term maintenance on these icebreakers has been deferred over the past several years, making the ships inefficient to operate and their technological systems outdated. Congress asked the National Academies to provide a comprehensive assessment of the current and future roles of U.S. Coast Guard polar icebreakers in supporting U.S. operations in the Antarctic and the Arctic, including scenarios for continuing those operations and alternative approaches, the changes in roles and missions of polar icebreakers in the support of all national priorities in the polar regions, and potential changes in the roles of U.S Coast Guard icebreakers in the Arctic that may develop due to environmental change. This brief interim report highlights the most urgent and time-dependent issues, and a final report, expected to be released next summer, will examine the type and number of icebreaking ships that the U.S. requires in the long term and other issues.

This book was released on 2007-03-14 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Propulsion Tests in Level Ice on a Model of a 140 ft WTGB Icebreaker written by Jean-Claude Tatinclaux and published by . This book was released on 1985 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of propulsion tests in level ice on a model of the WTGB 140-ft. Great Lakes icebreaker are presented and compared to available full-scale data. In spite of the difficulties in exactly modeling full-scale conditions, the predictions based on the model test results of the ship performance compared reasonably well to those measured during full-scale trials. Several possible sources of errors are identified. In particular, duplication at the model scale of the ship hull's ice friction coefficient is considered to be critical in determining the ice resistance and the corresponding propulsion characteristics, namely propeller speed, thrust and torque. Keywords: Coast Guard ships; Ship models; Icebreakers; and Model tests.
