The Optimization of Parameters for Ships Navigating in Ice
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.
Icebreakers
Traveling by boat in cold climates would be extremely difficult without icebreakers. These special boats help create paths in ice that allow other vessels to travel frigid, ice-filled waters to deliver people and supplies to places often inaccessible without their hard work. Readers will dive in to explore how icebreakers work and what special tools they have to keep other boats safe in the water. Full-color photographs show icebreakers leading ships to Antarctica and other ice breaking projects while exploring the other places these boats work around the world.
Impact of Operational Conditions of Icebreaker Ships on the Optimal Type of Propulsion System
Introduction -- Methodology to select the appropriate type of propulsion system -- The local indicators of icebreaker ships in operational modes -- Models to compare comprehensive efficiency of propulsion systems in operational conditions -- Comprehensive efficiency of icebreaker ships with different propulsion systems -- Conclusion.
Icebreaker
*A Newstatesman Book of the Year* ‘Nimble, vital, unexpectedly affecting’ Observer Bestselling travel writer Horatio Clare joins an icebreaker for a voyage through the ice-packs of the far north. 'We are celebrating a hundred years since independence this year: how would you like to travel on a government icebreaker?' A message from the Finnish embassy launches Horatio Clare on a voyage around an extraordinary country and an unearthly place, the frozen Bay of Bothnia, just short of the Arctic circle. Travelling with the crew of Icebreaker Otso, Horatio, whose last adventure saw him embedded on Maersk container vessels for the bestseller Down to the Sea in Ships, discovers stories of Finland, of her mariners and of ice. Aboard Otso Horatio gets to know the men who make up her crew, and explores Finland’s history and character. Surrounded by the extraordinary colours and conditions of a frozen sea, he also comes to understand something of the complexity and fragile beauty of ice, a near-miraculous substance which cools the planet, gives the stars their twinkle and which may hold all our futures in its crystals.
Polar Icebreakers in a Changing World
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 c...
Arctic Icebreaker Louis S. St-Laurent
Boats can carry games and bikes across the ocean. They are used for fishing and sailing. But some boats save other boats. The Arctic Icebreaker Louis S. St-Laurent rescues ships stranded in the frozen Canadian north. It also helps villagers who live in the Arctic Circle. It is even protecting people by helping scientists learn more about warming oceans and rising seas.
Polar Icebreaker Roles and U.S. Future Needs
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 continui...
Coast Guard Polar Icebreaker Modernization
Of the Coast Guard¿s (CG) 3 polar icebreakers, 2 ¿ Polar Star and Polar Sea ¿ have exceeded their intended 30-year service lives. Potential policy issues for Congress regarding CG polar icebreaker modernization include: the numbers and capabilities of polar icebreakers the CG will need in the future; whether to provide these icebreakers through construction of new ships or service life extensions of Polar Start and/or Polar Sea; whether new ships should be funded entirely in the Coast Guard budget, or partly or entirely in some other part of the fed. budget; and whether the Polar Star should be repaired and placed back into service. Charts and tables.
Coast Guard Polar Icebreakers
Polar icebreakers can operate in the extreme conditions of, and break through the thick ice found in the Arctic Ocean and the waters surrounding Antarctica. Congress has expressed concern about the Coast Guard's ability to meet its polar operations mission requirements in light of the condition of the Coast Guard's polar icebreaker fleet, and directed the Coast Guard to submit a comprehensive report on polar operations. This book examines the issues facing Congress on whether it will approve or modify the Coast Guard's plan for modernising its polar icebreakers. Congressional decisions on this issue could affect the Coast Guard's ability to perform its polar missions, funding requirements and U.S. shipbuilding industrial base. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.
