Alternative advanced power systems designed to operate a 500-ton submersible have been examined with respect to overall weight and volume fractions. Two-week and one-month missions, with and without the conventional “at-sea” recharge capability, were considered to evaluate the impact of advanced technologies on non-nuclear submarine design. Candidate air-breathing, primary-power systems studied included Diesel, Closed-Brayton Cycle (CBC), and fuel cells. A number of options for underwater operation were based upon high-energy reactants replenlshable from Base supplies. Another set of options was considered based upon using JP-S fuel with “at-sea” rechargeable secondary power systems, including thermal-energy storage, advanced lithium-sulfur batteries, or flywheels. Replenlshable high-energy reactant systems were, on average, lower in weight and volume than the rechargeable systems for the same submerged-mission profile. Moreover, the replenlshable systems permitted an extended tactical encounter with a maximum duration of 8 to 17 hours at speeds of 30 knots without the need to resurface and recharge a secondary energy storage device. The lowest-weight rechargeable systems in the order of increasing weight were the CBC engine with advanced lithium-sulfur battery, the CBC engine with carbon-block (thermal energy storage), and the Diesel engine with advanced lithium-sulfur battery. The rechargeable systems required unacceptable weight fractions in both missions. The high-energy (replenlshable from Base supplies) systems, with the exception of the heavy acid fuel cell using LOX, were all acceptable candidates for application in the two-week mission. Only the CBC engine with a llthium-sulfurhexaflaoride heat source, the lowest-weight system in both mission groups, was acceptable for the one-month mission.

The domestic production of the most powerful ozone-depleting substances (ODSs) has permanently ceased and the abundant supplies of a number of refrigerants, fire-fighting agents, and solvents, once taken for granted, are now a thing of the past. The Navy has adopted a successful strategy for addressing the threat posed by the unavailability of ODSs. That strategy includes relying on a strategic reserve of ODSs. Considering that the strategic reserve will play a critical role in sustained Fleet operations into the middle of the century, it is important to record the history of the reserve and to document lessons learned in order to educate future generations that may face similar challenges. This is the third of three papers that cover all aspects of the Navy's strategic reserve of ODSs. Breslin (1999) documented the history of the Navy's effort to size, establish, and monitor a reserve designed to support Fleet operations until the middle of the century. Breslin, Smith, and Toms (2000) addressed in detail the process used to estimate the required size of the reserve, including the survey method, statistical analyses, and sizing algorithms. This paper discusses the Navy's plan for monitoring the Navy's strategic reserves of ODSs and describes the methods used in the monitoring process. In particular it discusses the underlying assumptions and statistical techniques associated with the Navy's prediction of the expected drawdown of the reserves. A comparison of actual data, collected since the strategic reserves began operations in 1995, with the predicted reserve drawdown, is included in the paper.

Cracking was discovered in the openings of cargo deck tie down fittings on ships under construction. There was a distinct possibility that these cracks could propagate through the fittings and into the strength deck plating, affecting the ships hull integrity. With more than 14,000 fittings installed on each ship, the appearance of approximately 400 cracks at the mid-ship area of the main and lower decks raised production and operational concerns. This paper will discus the successful application of a Root Cause Failure Analysis (RCFA) methodology employed by a Corrective Action Team (CAT) establish to solve the problem. Through their efforts and the systematic application of RCFA, various failure hypotheses were validated or discounted and consensus was achieved on the appropriate corrective action.

This paper discusses the need and processes for designing warships to meet cost constraints and for managing warship acquisition programs during the design phase to assure effective adherence to production cost constraints by the design team. The resource control methodology used during the contract design of the Arleigh Burke class destroyer, DDG-51, is examined as a potential model for controlling the cost while maintaining the combat effectiveness of warships. The paper begins with a summary of the basic issue — the relationship among unit cost, unit capability, force level numbers, and force capability — showing recent trends in destroyer costs and force levels. This introduction also includes a discussion of the cost constraint for the DDG-51 in relation to historical trends and ship construction funding allocation. The resource control methodology used to reduce and control costs of the DDG-51 is discussed with a summary of the approach, key concepts and tools, chronology of key events, examples, and results achieved. A number of observations on this methodology are then made which are followed by comments on life cycle costs. The paper concludes with remarks on the future application of the resource control methodology and areas for further work to improve future resource control efforts.

A research group at the Massachusetts Institute of technology has completed the first phase of the development of a computer assisted model for analyzing complex decisions and policies regarding oil spill cleanup. The model is the product of an ongoing MIT Sea Grant project, sponsored by a consortium of government and industry organizations, including the National Oceanic and Atmospheric Administration, the U.S. C oast G uard , the U.S. N avy , the Commonwealth of Massachusetts, the Spill Control Association of America, JFB Scientific Corporation, the Doherty Foundation, Petro-Canada and Texaco. The model can be used, among other things, in strategic planning for the long-term oil spill response needs of a region, in assisting On Scene Coordinators in responding to a specific spill (tactical/operational setting), in evaluating the environmental and economic damages of a spill versus the cost of cleanup, in simulation and training, and in the analysis of various policy and regulatory issues such as the effects of delays, the use of dispersants and the investigation of liability and compensation issues. The paper describes the model in detail, focuses on its potential uses and presents experience with its application in conjunction with pollution control efforts of the U.S. Navy. Specifically, we outline the application of the model in the Port of Charleston, South Carolina, an ongoing project sponsored by the Naval Facilities engineering Command. The difficulty of gathering data for such an application is discussed.

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
