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has been deferred over the past several years, making the ships inefficient to operate and their technological systems outdated.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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

This book was released on 2020-05 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: "For a large number of countries, the task of Arctic exploration and implementation of year-round navigation along the Northern Sea Route, which has become a reality today due to global warming, has become increasingly relevant in recent years. In turn, its solution requires the creation of a multi-purpose Arctic fleet, consisting of modern icebreaker ships with efficient and fault-tolerant propulsion systems, fully compliant with the specific operational conditions of the Arctic. In the last decade, due to the significantly increased interest to the new transport connection between West Europe and the Far East and the growth of various cargo traffic (oil, gas, containers, etc.) by the Northern Sea Route, the need of a significant increase of quantity and capacity of icebreaker cargo fleet has appeared. In order to maintain year-round navigation in the Northern Sea Route in the next few years, ships for various purposes are planned to be built (multipurpose and universal ships, supply ships, lighters, oil and gas tankers, hovercrafts, and others), which are intended for operation in the seas of the Arctic basin. Comprehensive efficiency of transportation process in the Arctic seas depends not only on the planning and coordination activities of the fleets and harbors, but also on the ships' technical characteristics. It means that icebreaker ships should have appropriate special features, accordingly to the requirements for navigation in the Arctic ice conditions. The results of the presented scientific research, which are based on statistical operational data from the 1980s, determined the main directions for development of today's modern icebreaker ships designed for Arctic operation in specific ice conditions. Considering that the projects of year-round navigation along the Northern Sea Route, which have become a reality today, the task of creating corresponding ships with highly reliable and fault-tolerant electric propulsion systems is extremely relevant today. The proposed systematic methodology of the choice of the appropriate type of propulsion system for icebreaker cargo Arctic ships was confirmed by many years of successful operational experience in the ice navigational conditions. During the design process of icebreaker ships, the question about choice of ship's propulsion system arises, taking into account a power-producing unit and propeller, coupled with the frame of the ship. The correct solution of this problem has a significant value for the further operation of the ship. The aim of this book is to provide a comprehensive presentation of multicriteria operational efficiency analysis of the competing ship's propulsion systems that would be most suitable for icebreaker Arctic ships, taking into account the real operating conditions of ice navigation"--

Book excerpt: 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.

Download or read book Coast Guard Polar Icebreaker Modernization written by Ronald O'Rourke and published by Createspace Independent Publishing Platform. This book was released on 2017-04-03 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operational U.S. polar icebreaking fleet currently consists of one heavy polar icebreaker, Polar Star, and one medium polar icebreaker, Healy. In addition to Polar Star, the Coast Guard has a second heavy polar icebreaker, Polar Sea. This ship suffered an engine casualty in June 2010 and has been non-operational since then. Polar Star and Polar Sea entered service in 1976 and 1978, respectively, and are now well beyond their originally intended 30-year service lives. Coast Guard polar icebreakers perform a variety of missions supporting U.S. interests in polar regions. A Department of Homeland Security (DHS) Mission Need Statement (MNS) approved in June 2013 states that "current requirements and future projections ... indicate the Coast Guard will need to expand its icebreaking capacity, potentially requiring a fleet of up to six icebreakers (3 heavy and 3 medium) to adequately meet mission demands in the high latitudes...." The current condition of the U.S. polar icebreaker fleet, the DHS MNS, and concerns among some observers about whether the United States is adequately investing in capabilities to carry out its responsibilities and defend its interests in the Arctic, have focused policymaker attention on the question of whether and when to acquire one or more new heavy polar icebreakers as replacements for Polar Star and Polar Sea. On September 1, 2015, the White House issued a fact sheet indicating that the Administration wants to begin building a new polar icebreaker in FY2020, and that the Administration will also "begin planning for construction of additional icebreakers" beyond the one that the Administration proposes to begin building in FY2020. On October 26, 2016, the Coast Guard released a request for information (RFI) to receive industry feedback on its notional polar icebreaker acquisition approach and schedule. The summary of the RFI, dated October 25, 2016, presents a notional schedule for acquiring three heavy polar icebreakers under which procurement of long leadtime materials (LLTM) for the three ships would start in the fourth quarter of FY2019, the second quarter of FY2021, and the second quarter of FY2022, respectively, and the ships would be delivered in the fourth quarter of FY2023, the second quarter of FY2025, and the second quarter of FY2026, respectively. (Each ship would be commissioned into service a few weeks or months after it is delivered.)
