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.

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.

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.

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 application of computers in acquisition and logistics support is to major requirement of future weapons systems acquisitions. Although the design of the SEAWOLF preceded most new DOD sponsored requirements, the program incorporated many initiatives that will serve as prototypes for most acquisitions. It The SEAWOLF Program is employing computer technology to integrate the design, production and logistic the ship's life cycle. The transportabiiity of TI electronic data from the design phase ti to construction, and on to logistics dc is key to improving efficiency and a more closely linking designer, shipbuilder and maintainer. SFAWOLF is an important step in the overall effort to improve weapons system acquisition efficiency. Five Lessons learned by SEAWOLF will be valuable in preparing other acquisition programs to take advantage of the integration of computer data bases that can bring greater success in the execution of design, production mi and logistics support phases.

A Mid-Term Fast Sealift Technology Development Program producibility study was undertaken by the Manufacturing Systems Division (Code 125) of the Naval Surface Warfare Center, Carderock Division (NSWC) for the Naval Sea Systems Command Computer Aided Engineering Division, Ship Design and Engineering Directorate, SEA 507. The producibility project team was initially tasked to identify and evaluate possible design improvements with regard to their potential impact upon the cost of construction for the Baseline (BL) Oa rough order of magnitude (ROM) geared-diesel option. This particular design varient is a 30 kt twin screw, 289 m (948 ft.) roll-on/roll-off (RO/RO) vessel with four 18 PC4.2V medium speed diesels producing 85,619 kilowatts (114,817 h.p.) of installed power. The construction cost estimate developed by NAVSEA for this particular design varient is $385 million per ship (I). In addition to the NAVSEA-assigned task, the team reviewed the producibility aspects of the Navy auxiliary ship procurement process with regard to finding methods that would facilitate major reductions in the construction contract cycle, as time is now recognized as a major cost driver in ship procurement (2). The construction contract cycle is defined as the amount of time from construction contract award to delivery, and was estimated by NAVSEA to be 42 months for this particular design varient (3).
