David Taylor Research Center is just commencing investigations into a new manner of defining future fleet architectures. The cost of current performance-driven ship designs has increased at a rapid rate. While it is true that a warship designed with insufficient performance is of meager utility it is also true that the heat performing warship design is of no utility if never built. Both performance and affordability are required if sufficient numbers of ships are to be built to counter the threat. By designing a future fleet architecture with producibility as a major requirement from the start we hope to impact the acquisition cost significantly. One battle force concept titled Distribute, Disperse, Disguise and Sustain suggests two fundamental surface ship types; the Carrier of Large Objects (CLO) and the Scout Fighter. A CLO feasibility design in progress Carrier Dock Multimission is outlined to inform shipbuilding researchers of an initiative that promises to have significant impact on naval ship procurement and provide increased visibility within the U.S. Navy on producibility issues.

Much attention has been given in recent years to the problem of reducing ship construction costs. This has primarily emphasized the improvement of production techniques, processes and management controls. There is a great deal that can be accomplished in reducing ship construction costs, however, by improving the producibility of the design of the ship. The design of a more producible ship requires concurrent product and process design. Various principles and techniques can be applied throughout the design process in order to reduce the construction manhours required by ensuring that the manufacturing attributes are considered. This paper identifies some of the key principles involved and describes the techniques for applying the principles. A practical approach to estimating the cost benefit of alternative designs by estimating the labor input differential between the designs 25 also presented. Finally, specific examples of the application of the producibility techniques to several recent ship designs are included.

The application of Computer Aided Design (CAD) and Manufacturing (CAM) techniques in the marine industry has increased significantly in recent years, With more individual designers and ship yards using CAD within their organizations, the pressure to transfer CAD data between organizations has also increased. The Navy/Industry Digital Data Exchange Standards Committee (NIDDESC) prow-ales a mechanism for public and private organizations to cooperate in the development of digital data transfer techniques.

In October 1989, A Ship Design for Producibility Workshop was held by the Naval Sea Systems Command (NAVSEA) at the David Taylor Research Center (DTRC). The purpose of the workshop was To develop the framework of a plan to integrate producibility concepts and processes into the NAVSEA Ship Design Process. The major recommendations of the workshop included initiatives related to increased training of NAVSEA design engineers in modem ship production concepts, development of producibility design tools and practices for use by NAVSEA design engineers, improved cost models, implementation of produability strategies for ship design process improvements, modification to existing acquisition practices, and improved three-dimensional (3-D) digital data transfer. The workshop was one of NAVSEA s first Total Quality Leadership (TQL) initiatives and was subsequently expanded into the Ship Design, Acquisition and Construction @AC) Process Improvement Project. This paper reports on the major findings and recommendations of the workshop, the near term accomplishments since the workshop, and the long range strategic plan for continuously improving producibility in the Naval Ship Design Process.

SEAWOLF Producibility initiatives have been presented to past Ship Production Symposiums. The technical content of these papers was based on work accomplished during the SEAWOLF Detail Design effort and articulated the point of view that the SEAWOLF Producibility Program was an important step in advanced ship production. The lead shiv of the SEAWOLF Class started construction in late 1989. The opportunity now exists to validate a number of the elements of the design for production. Electric Boat Division, as Lead Shipbuilder, has the opportunity to review a number of the specific initiatives, such as Digital Data Transfer, Sectional Construction Drawings, Planning and Sequence Documents, Computer Integration of information processing and the combination of SEAWOLF products that support improved work control. The method of approach is to describe the SEAWOLF producibilitv element developed during detail -design and then assess the benefit to the shipbuilding process.

After years of studies, reports, formal and informal discussions, Naval ship producibility is becoming accepted as a necessary ingredient in any recipe for affordable, effective warships. However, within both the Navy ship design and private ship construction communities, the word producibility has come to evoke a wide variety of reactions. While there is general agreement that producibility has to do with lowering ship costs, there is not yet a consensus on how those costs are to be attacked, what factors are the most important, and what the roles of the various participants should be. In order to answer these and other questions, and to form a consensus within the Navy design community that will be compatible with external as well as internal relationships, the Naval Sea Systems Command (NAVSEA) has sponsored a series of steering committee meetings and a workshop on producibility as part of its ongoing research. The purpose of these meetings and workshop is to clarify the meaning of producibility, the needs of the design and construction communities, and to determine critical actions which will enable NAVSEA to integrate producibility more thoroughly into the Naval ship design process.

The paper discusses, from a ship designer's perspective, some of the current topics and issues relating to the interface between naval ship design and production. The current environment within which naval ship design activity is taking place is described. Notable current views on Navy ship design and how it might be improved are summarized. Navy design topics pertinent to improving ship producibility, operability, maintainability and survivability are discussed and examples from recent ship designs are presented. Issues which result from apparent conflicts in current design initiatives and critiques of the Navy ship design process are highlighted and discussed. Finally, some general conclusions are drawn.

In the past two decades, the U.S. Navy has undertaken significant projects in the computer aided design, manufacturing, and service life support areas. A few of the those most related to the shipbuilding programs are listed in Table 1 along with the phase in the ship's life cycle they were primarily supporting. CASDAC (Computer Aided Ship Design and Construction) was the grandaddy of them all, dating back to the late 60s when the Navy was designing and building its own ships. The project's goal was to develop software for doing early stage design, through contract design, and detail design at the naval shipyards. They labored under the dual burdens of expensive hardware and relatively unfriendly software development environment, with clumsy operating systems, occasional need for assembly language programming, and early compiler limitations ions. Nevertheless, many programs that are still with us today began during that era, including: SHCP (Ship Hull Characteristic Program) ; SSDP (Ship Structural Design Program) ; HULDEF (Hull form Definition); and SDWE (Ship Design Weight Estimating). The state of CASDACVs progress by the early and mid 7Os is well described in references [1] and [2]. The monument al CASDOS (Computer Aided Structural Detailing of Ships) was developed under CASDAC's sponsorship and actually used to build 6 LCUs for the Army and for Saudi Arabia. Over half of CASDAC's efforts were oriented toward shipyard product ion software, including electrical wiring and fluid piping systems programs. In 193l, long after the end of new ship construction at the Navy yards, CASDAC was subdivided into two distinct programs, the CSD (Computer Supported Design) programs, carrying on the ship design software development, and portions of the MANTECH (manufacturing and technology) program for advancing industry's efforts to improve shipbuilding productivitiy through automation and technology.
