This book was released on 1967 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Icebreakers impose limitations on a propulsion system that have been solved historically by the use of a D.C. motor directly coupled to the shaft driving the propeller. With the advent of high power silicon rectifier devices, several members of the Westinghouse Electric Corporation published papers which suggest the use of these rectifiers in an alternating current (A.C.) to direct current (D.C.) electric propulsion system for icebreakers. It was suggested that the use of this conversion type propulsion system would provide an icebreaker with the proven and inherent advantages of a D.C. motor and would provide weight, cost, efficiency, reliability and maintenance advantages due to the use of A.C. generating equipment. The purpose of this work is to examine proposed A.C. to D.C. propulsion systems using silicon rectifier conversion equipment with the following objectives: Discussion of the A.C. - D.C. propulsion system with senior industry personnel with the intent of determining that the propulsion system can be manufactured with current technology and that a development program will not be necessary. Determination that the performance of an icebreaker using an A.C. to D.C. propulsion system would be at least comparable to that in currently operating U.S. Coast Guard icebreakers. Determination of the advantages and disadvantages of the A.C. - D.C. propulsion system when compared to a D.C. propulsion system. Determination that there are no known considerations which make silicon rectifier units unsuitable for use in a marine environment or in an icebreaker propulsion system.

This book was released on 2018-06-11 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: The only book that covers fundamental shipboard design and verification concepts from individual devices to the system level Shipboard electrical system design and development requirements are fundamentally different from utility-based power generation and distribution requirements. Electrical engineers who are engaged in shipbuilding must understand various design elements to build both safe and energy-efficient power distribution systems. This book covers all the relevant technologies and regulations for building shipboard power systems, which include commercial ships, naval ships, offshore floating platforms, and offshore support vessels. In recent years, offshore floating platforms have been frequently discussed in exploring deep-water resources such as oil, gas, and wind energy. This book presents step-by-step shipboard electrical system design and verification fundamentals and provides information on individual electrical devices and practical design examples, along with ample illustrations to back them. In addition, Shipboard Power Systems Design and Verification Fundamentals: Presents real-world examples and supporting drawings for shipboard electrical system design Includes comprehensive coverage of domestic and international rules and regulations (e.g. IEEE 45, IEEE 1580) Covers advanced devices such as VFD (Variable Frequency Drive) in detail This book is an important read for all electrical system engineers working for shipbuilders and shipbuilding subcontractors, as well as for power engineers in general.
Download or read book Icebreaker Propulsion Systems Feasibility Study Volume III Conventional Propulsion Systems written by NUS CORP ROCKVILLE MD. and published by . This book was released on 1966 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase I of the Icebreaker Propulsion Systems Feasibility Study evaluates the relative economic merits of nuclear and conventional propulsion plants for a range of ship horsepowers and for a specific operations mission. This volume describes the results of this evaluation as it pertains to the conventional oil-fired prime mover systems and the power conversion or transmission systems. To obtain a definitive economic comparison of candidate propulsion plants on a consistent basis, it was necessary to perform the following major tasks: Define the design and performance requirements of icebreaker propulsion systems and derive preliminary design criteria; Define economic parameters and bases for cost analysis of capital, fuel, manning, and maintenance costs; Develop a reference design of each type propulsion system capable of meeting the performance and safety requirements and which would have economic merit; Perform comparative economic analyses of the reference propulsion plant designs.

Available in PDF, EPUB and Kindle. Book excerpt: The future national security environment will present the naval forces with operational challenges that can best be met through the development of military capabilities that effectively leverage rapidly advancing technologies in many areas. The panel envisions a world where the naval forces will perform missions in the future similar to those they have historically undertaken. These missions will continue to include sea control, deterrence, power projection, sea lift, and so on. The missions will be accomplished through the use of platforms (ships, submarines, aircraft, and spacecraft), weapons (guns, missiles, bombs, torpedoes, and information), manpower, materiel, tactics, and processes (acquisition, logistics, and so on.). Accordingly, the Panel on Technology attempted to identify those technologies that will be of greatest importance to the future operations of the naval forces and to project trends in their development out to the year 2035. The primary objective of the panel was to determine which are the most critical technologies for the Department of the Navy to pursue to ensure U.S. dominance in future naval operations and to determine the future trends in these technologies and their impact on Navy and Marine Corps superiority. A vision of future naval operations ensued from this effort. These technologies form the base from which products, platforms, weapons, and capabilities are built. By combining multiple technologies with their future attributes, new systems and subsystems can be envisioned. Technology for the United States Navy and Marine Corps, 2000-2035 Becoming a 21st-Century Force: Volume 2: Technology indentifies those technologies that are unique to the naval forces and whose development the Department of the Navy clearly must fund, as well as commercially dominated technologies that the panel believes the Navy and Marine Corps must learn to adapt as quickly as possible to naval applications. Since the development of many of the critical technologies is becoming global in nature, some consideration is given to foreign capabilities and trends as a way to assess potential adversaries' capabilities. Finally, the panel assessed the current state of the science and technology (S&T) establishment and processes within the Department of the Navy and makes recommendations that would improve the efficiency and effectiveness of this vital area. The panel's findings and recommendations are presented in this report.
