The paper will describe the streamlined acquisition process involved in the procurement, and conversion, of the first two of three Enhanced Maritime Prepositioning Force (MPF(E)) ships. This program was one of the first programs undertaken within the Government's new policy of Acquisition Reform, which resulted in the development of "performance based" requirements for these ships. This program is notable in that one prime contractor is responsible for the accomplishment of all phases, and that the contractors participating were not shipyards as is usually the fashion for Government ship acquisition programs. Also of note, was that after the conversion contracts were awarded, responsibility for the conduct of detail design, conversion, and operation and maintenance of the ship was transferred from the NAVSEA Sealift program Office (PMS 385) to the Military Sealift Command (MSC). The first part of the paper will describe the basic mission of the MPF(E) ships, and a description of the origin of the program requirements. The second part of the paper will chronicle in detail the portions of the engineering design and specification development process, which will include descriptions of the unique digital data recording and tracking systems developed by the Government MPF(E) Design Support Team to support the acquisition phases of the procurement. The third and final part of the paper will elaborate on the conversion contract awards and the transition of the program from PMS 385 to MSC.

Through a detailed Research and Development program, the U.S. Navy has developed a suite of shipboard solid waste management equipment enabling compliance with federal and international law. Four major equipment types have been developed to outfit twenty-seven classes of naval surface ships. The major equipment types are: Plastic Waste Processor (PWP), Metal/Glass Shredder (MGS), Large Pulper (LP), and Small Pulper (SP). The Navy is aggressively procuring and installing this equipment aboard all ships of FFG 7 Class and larger. A deadline of December 31, 2000 has been set for completion. engineering analysis and held waste generation studies were conducted to select the specific equipment suite and develop alteration documentation for each ship class. Specific factors in this process were: solid waste generation rates, equipment reliability analysis, ship arrangement considerations, daily equipment operation Limits, and shipboard quality of life issues. A solid waste management study was conducted in the fall of 1997 to validate Navy equipment and ship design parameters onboard the USS John C. Stennis (CVN 74). Generation rates for shipboard solid waste were determined for plastic, metal and glass, food, paper, cardboard, fabric and wood. engineering analysis of data allowed a decrease in CVN 68 Class design waste generation rates. engineering analysis enabled a reduction in the number of PWPs and MGSs required, and fewer spaces for efficient operation. Ship arrangement studies were conducted to optimize efficiency and equipment mix of Solid Waste Processing Rooms (SWPRs) relative to waste generation sites. This paper briefly articulates the process followed by the Navy in responding to regulations governing solid waste management in the marine environment. Evidence validating the engineering procedures followed is presented.

The Defense Advanced Research project Agency (DARPA), in conjunction with the U.S. Navy, initiated a research program for the design and construction of a distinctive warship for the 21st century known as the Arsenal Ship. By using an innovative development and acquisition approach it was hoped to streamline the procurement process and reduce costs. In an environment where budgets are being cut, both industry and Government were challenged to develop, design, and produce the innovative ship and related mission systems to meet specific performance capabilities within strict affordability constraints. A key element of this innovative acquisition approach was a new certification scheme designed to replace the traditional test and evaluation (T&E) and acceptance process. The purpose of this paper is to describe the development of the certification plan during Phase LI of the Arsenal Ship program by the American Bureau of Shipping and the contending Shipyard teams, and to discuss the potential benefits of this alternative certification approach. Although the Arsenal Ship program was canceled late in 1997, insight derived from the exploration of new certification concepts could benefit future design and building programs.

NAVAL ENGINEERS JOURNAL 1996年第3期108卷 335-339页

作者： Goodnow, MO Rumburg, JW [?]Michael O. Goodnow received a Bachelor of Science degree in Electrical Engineering from Virginia Polytechnic Institute in 1981 and a Master's degree in Engineering Management from The George Washington University in 1994. Mr. Goodnow worked for the Baltimore Gas and Electric Company in both the Electric Operations Department and the Electric Construction Department utilizing his background in electrical power until 1985 when he began to work for the Navy. For the past ten years he has been heavily involved in shipboard power distribution systems design and improvement. He has been the project manager of the Electric Power Survivability Program for the Naval Surface Warfare Center in Annapolis Maryland for the past five years. He is a member of IEEE.

For many years, electrical cable exposed to fragmentation was never taken into consideration in fault predictions for electrical power distribution systems. Testing, which began in 1990 by NSWC Annapolis under the Electrical Power Survivability program, to evaluate the effects of combat casualty on electrical power distribution systems, verified that a condition of multiple simultaneous faults could occur from typical weapons threats. Four phases of testing were performed to characterize damage to electrical power cables. These four testing phases were severing a single energized power cable, fragmenting multiple power cables fed from a single source and fragmenting multiple power cables fed from multiple sources. This paper reviews the various phases of testing conducted from the inception of the program and the test results.

Currently he serves as the assistant production officer at SUPSHIP Bath in charge of DDG 51 class construction and delivery.

This paper describes the design of a Regional Deterrence Ship (RDS 2010) for the 2010 timeframe. The requirements for the design were for a ship to operate in littoral areas of the world with a mission of deterring regional conflicts and of hampering the efforts of the aggressor in such a conflict. In addition the ship's mission included the evacuation of friendly personnel as hostilities become likely. The problem countering the littoral threat during times of constrained budgets is addressed. Top level requirements for the design, generated in parallel with ''.... From the Sea'' [1], were used to set the design goals. The paper describes the manner in which littoral warfare changes the nature of the challenges faced by Navy surface combatants, including a ship such as the RDS 2010. A number of factors become more crucial design concerns than for blue water ships, including reduced reaction times, likelihood of attack from hidden land sites, shallow water mines and shallow water USW Certain other factors become less critical in littoral areas and this also has ship design impacts. While some present ship designs can perform some of the tasks needed in a littoral warfare/regional conflict environment, none represents a completely integrated design (hull, mechanical & electrical;combat systems;fiscal and manning constraints;reduced vulnerability;robust self-defense etc.) for a vessel stationed in waters that, without warning, can become hostile. After describing the mission requirements to which the RDS 2010 was designed, the paper discusses the controlling design philosophy and decisions and describes the process used to assess threats to the ship. The process of combat system selection, against the backdrop of expected threat scenarios, is described and the intended approach to integration of the combat system is discussed. In recognition that decreased reaction times and surprise attacks are likely to threaten a ship engaged in regional deterrence, discussions oi

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

Live Fire Test and Evaluation (LFT&E) is a relatively recent addition to the requirements for ship acquisition programs. Ship LFT&E requires a combination of testing and analysis in order to evaluate the vulnerability of a new acquisition ship class to the threat weapons it is likely to encounter in combat. LFT&E supports the ship acquisition process by identifying vulnerability weaknesses early in a development program and enabling timely, well informed decisions regarding ship vulnerability reduction features. This paper discusses the various aspects of ship LFT&E and how they relate to make a positive impact on a ship acquisition program in a timely fashion. It describes a four-element approach to ship LFT&E consisting of (1) component, system, and full-scale ship tests, (2) surrogate tests, (3) damage scenario-based engineering analyses, and (4) a Total Ship Survivability Trial demonstrating the ability of the full-up ship to combat damage and ''fight hurt.''

The best value concept is based on making decisions on an offeror's technical competence, proven past performance, management capability, life-cycle costs, and product quality. The evaluation of these factors should be structured to ensure consideration is given to determine the overall benefit associated with the offered price. This paper advocates using the best value concept as the method for developing and rating proposal evaluation factors for the procurement of new ships. It discusses methods for establishing evaluation factors, developing standards to evaluate, associated documentation, and weighting and scoring the factors. The information for this paper was obtained from personal interviews, hands-on experience developing and evaluating best value proposals, and documentation research. If properly executed, the best value concept will enable the Navy to improve ships while reducing operating costs.

''Turn-Key'' is an innovative approach for the design, acquisition, integration, and installation of Radio Communications Systems for new construction ships. It has been developed bv the Space and Naval Warfare Systems Command (SpaWar) to cope with the growing problem of ships being delivered to the fleet with outdated or obsolete communications technology. The Turn-Kev approach provides botb performance and affordabilitv benerits. Under the traditional ship design process, the baseline configuration of the communications suite is effectivelv frozen 5-7 years before deliverv of the ship. In the current fixed price shipbuilding environment, the costs of engineering change proposals (ECPs) to implement communications suite design changes have become prohibitive. The design inflexibilitv created by these schedule and cost constraints affects the Navv's abilitv to implement communications technology advancements in new construction ships. At the point of delivery, most new construction ships alreadv have an inherent ''bow-wave of required communications subsystem/equipment upgrades which must be accomplished under the Fleet Modernization program. Under the turn-kev approach, the Navv assumes full responsibility for design, acquisition, land-based system integration, and (in some cases) shipboard installation and test of the communications suite. The shipbuilder provides necessarv electrical power, ventilation, and cooling services, based on established allocations. This approach greatly reduces the Navy's GFI requirements and ECP costs to the shipbuilder and therebv gains the design flexibilitv necessarv for incorporation of up-to-date communications technology prior to ship delivery. Since the shipbuilding ECP cost penalties associated with implementing communications technology upgrades are reduced, the turn-key approach enables performance improvements while providing affordabilitv benefits. The turn-key approach already has been used successfully for installation of

THE AUTHORS 6 ABSTRACT Shipboard weather deck ice removal is a laborious, time consuming, dangerous task. The current operational scenario consists of sailors wielding hickory baseball bats. This paper describes a viable alternative, the Electro-Expulsive Separation System (EESS), originally developed by NASA. EESS technology has been designed to remove ice from aircraft surfaces. Developmental testing, which led to acceptance of this new device, is discussed together with its theory of operation. The resultant aircraft applications are described. The need to adapt this aircraft technology for shipboard applications is recognized by the Navy, the Coast Guard, the State of Alaska, and the commercial shipbuilding industry. Fishing vessels risk sinking every winter due to excessive ice accumulation on their decks and superstructure. Navy and Coast Guard cold water operations have been hampered for centuries due to severe ice accumulation during inclement weather. With the encouragement and cooperation of the State of Alaska, an EESS test program was formulated and subsequently conducted aboard an Alaskan Resources vessel in the Bering Sea. This testing is described, with lessons learned. Future test programs are identified, requisite for successful adaptation of this technology to combat and commercial shipboard applications.
