The ever increasing complexity of ships coupled with cost, schedule, and resource constraints require innovative methods by the Naval Sea systems Command's ship design community to meet this challenge. This paper describes the effort by the NavSea Ship Arrangement design Division to dramatically improve its ship design capability by the use of a system of computer-based design tools called the General Arrangement design system. The General Arrangement design system (GADS) is based on the engineering requirements of the ship arrangement design process. GADS is currently being used as a production engineering tool. This paper is organized into two parts. Part I describes the General Arrangement design system, and Part II describes the general arrangement design methodology.

NAVAL ENGINEERS JOURNAL 1986年第3期98卷 74-87页

作者： BROWER, KS WALKER, KW Kenneth S. Broweris a partner in Spectrum Associates Incorporated Arlington Virginia a naval architecture firm which he founded in 1978. He graduated from the University of Michigan in 1965 with a B. S. degree in naval architecture. Mr. Brower has contributed to the design and construction of numerous merchant ships and warships the latter of which include the CG-47 Project Arapaho the FDL and DX projects and the NA TO frigate replacement DDGX and FFX projects as well as several frigates developed for foreign military sales. Since 1972 he has actively participated in the Naval Sea Systems Command's comparative naval architecture program. During this period Mr. Brower has contributed to or been the author of numerous widely distributed technical reports on international ship design practices. A member of ASNE Mr. Brower was a recipient of the ASNE “Jimmie” Hamilton Award for 1983 for the article “Seakeeping and Combat System Performance—An Operator's Assessment” which he coauthored. Kenneth W. Walkeris a naval architect with Spectrum Associates Incorporated a firm which specializes in the development of ship design synthesis computer programs. He graduated from the Webb Institute of Naval Architecture in 1960 with a B.S. degree. Mr. Walker worked in the preliminary design division of the Naval Sea Systems Command and its precedent commands during the period between 1960 to 1977. He was employed primarily in conducting feasibility design studies and preliminary designs of naval ships. His work also included the development of subroutines for use in ship design synthesis computer programs under development and the documenting and flow charting of entire programs.

Naval ship design synthesis computer programs, the original development of which was pioneered by the U.S. Navy, are now used by the U.S. Navy to conduct feasibility design studies and to conduct reverse engineering analyses of foreign ships. The use of these computer programs has substantially reduced the time and cost of conducting feasibility design trade-off studies and has allowed the ship designer to develop very accurate design solutions that can be effectively used as the basis for preliminary and contract design. The paper describes an interpolative technique for ship design which the authors have developed and incorporated in a variety of ship design synthesis computer programs, without any loss in the accuracy of the design solution. The interpolative technique short cuts the classic and time consuming design spiral approach to conducting ship design studies, which was incorporated in the original ship design computer programs. The interpolative technique also significantly reduces computer operating costs and provides the ship designer with the flexibility required to quickly study the performance and cost impact of using any number of innovative ship configurations. The paper describes programming techniques and ship design logic which allow a ship design computer program to be used to study the impact of using alternative ship design criteria and practices, including different types of hull forms and stability criteria. Also discussed are alternative ways that ship design parametric data can be developed for use in a ship design synthesis computer program. An example of a ship design study which was conducted using the interpolative technique is shown.

作者： MASTRONARDE, TP The Author is manager proposal engineering Combustion Engineering Inc. Marine and Industrial Packaged Steam Systems. He graduated from Webb Institute of Naval Architecture in 1969 receiving his B.S. degree in naval architecture and marine engineering. He served in the U.S. Coast Guard as a staff naval architect in the Hull and Electrical Sections of the Merchant Marine Technical Group. Mr. Mastronarde joined Combustion Engineering in 1972 working in the area of marine steam generator design andperformance. Pursuing studies on heat transfer he received an M.S. degree in mechanical engineering from the University of Connecticut in 1977 Mr. Mastronarde has authored papers dealing with marine propulsion boiler performance and auxiliary and waste heat recovery steam system design and is currently responsible for proposal engineering for these products. A member of ASNE since 1972 he is also a member of SNAME and ASME.

On the CG-47 class, gas turbine electric generators are operating in a shipboard cogeneration system in conjunction with a successful and reliable waste heat recovery system which provides steam for auxiliary services. The current application philosophy for waste heat recovery from gas turbine auxiliary engines aboard Navy ships, however, has reached a technological plateau. The development and implementation of a second generation waste heat recovery system (WHRS) design could produce substantial benefits for future naval shipboard applications. This paper discusses methods of optimizing the interface between the gas turbine and the waste heat boiler, relocating boiler components, utilizing natural instead of forced circulation in the boiler, and reducing the complexity of feedwater treatment subsystems. Implementaion of integrated design features for a second generation waste heat recovery system could result in increased steam production, reduced boiler and auxiliary space requirements, reduced weight, and a lower shipboard center of gravity. In addition, a reduction in installed system cost and manhours spent on water treatment and routine shipboard maintenance could be obtained, along with significant, continued shipboard energy savings.

There is a great deal of emphasis currently in the Navy on the issues of reliability and maintainability. If a system or component is out of commission, it obviously cannot perform its mission. Thus, systems and components must be reliable, with low failure rates, and maintainable, with short repair times when the system does become inoperable. To be effective, these attributes must be incorporated into new ship systems early in the design stage. The Rankine cycle energy recovery (RACER) system is a heat recovery steam cycle designed to recover energy from the exhaust of an LM2500 gas turbine for augmentation of a ship's propulsion system. The RACER system provides several advantages to a gas turbine powered ship, one of which is improved fuel efficiency for significant annual fuel savings. This saving does not come free, however, since, in general, any additional system installed in the ship will have some maintenance requirements. In keeping with the Navy's current emphasis, a key philosophy in the design of the RACER system has been to minimize this maintenance burden. After a brief description of the RACER system and its design philosophy, the techniques being used during the design phase to minimize the maintenance burden on the fleet are presented. Trade-off studies concerning acquisition versus life-cycle costs, including fuel and maintenance costs, are discussed. Innovations incorporated into this state-of-the-art system are reviewed with an emphasis on design for affordability.

Air cushion vehicles (ACVs) have operated successfully on commercial routes for about twenty years. The routes are normally quite short; the craft are equipped with radar and radio navigation aids and maintain continuous contact with their terminals. Navigation of these craft, therefore, does not present any unusual difficulty. The introduction of air cushion vehicles into military service, however, can present a very different picture, especially when external navigation aids are not available and the craft must navigate by dead reckoning. This paper considers the problems involved when navigating a high-speed air cushion vehicle by dead reckoning in conditions of poor visibility. A method is presented to assess the ACV's navigational capability under these circumstances. A figure of merit is used to determine the sensitivity of factors which affect navigation such as the range of visibility, point-to-point distance, speed, turning radius and accuracy of onboard equipment. The method provides simplistic but adequate answers and can be used effectively to compare the-capability and cost of alternative navigation concepts.

An existing nonlinear ship design optimization program designated SHIPDOC has been extended and a new surface effect ship (SES) description input file is being developed under the sponsorship of the Naval Sea systems Command's surface ship concept formulation (CONFORM) program. SHIPDOC is currently being used in support of several feasibility and preliminary level SES designs. The program has several novel features including an open-ended, user-created ship description and the potential to model all types of ships both enhanced and conventional, surfaced and submerged. This capability has been combined with a nonlinear optimization algorithm that solves for the minimum weight ship subject to user controlled constraints. This paper presents a brief overall description of SHIPDOC and its current capabilities followed by a synopsis of ship types, both surface and submerged, which have been designed with the program in order to illustrate SHIPDOC's practical design capability.
