This paper describes a computer integrated engineering system for design and life cycle management of weapons systems, ships and other multidisciplined systems. All engineering data are stored in a central engineering database. Individual application databases define and process information necessary for specific discipline evaluations. Interface modules between the application databases and the engineering database ensure that the entered data are complete, consistent, compatible, and in compliance with requirements. Conflicts are immediately identified and efficiently resolved. Implementation of the system improves design quality and reduces costs by minimizing the number of design iterations, reducing the effort to implement changes, providing effective storage and retrieval, and reducing the need for ship checks prior to modifications and alterations.

JONS, OPKOELBEL, JSHELDON, ROtto Jons:is vice president of engineering at Advanced Marine Enterprises
Inc. He received a Diplom Ing. from the Technical University of Hannover W. Germany and an M.S. in naval architecture and marine engineering from the Massachusetts Institute of Technology in 1976. He then joined Litton Ship Systems to work on the DD-963 and LHA programs. He was principal research scientist at Hydronautics and technical director with Designers and Planners before forming in 1976 together with S. Glatz and J. Drewry Advanced Marine where he is responsible for engineering and technical matters on behalf of the corporation. Joseph Koelbel:
a senior naval architect at Advanced Marine Enterprises Inc. has for many years specialized in the design of high-speed rough-water boats including a record-setting race boat passenger boats and patrol boats such as the CPIC and the PBM. He received special recognition for his contributions to and editing of the Planing Concept Volume of the Advanced Naval Vehicles Concept Evaluation Study. He is a member of ASNE SNAME (past chairman planing boats panel of the Hydrodynamics Committee) and ABYC. He is the author of a number of published papers on small-craft design. Ray Sheldon:is the head of computer applications at Advanced Marine Enterprises
Inc. where he directs activities in computer-aided ship design software development and ship performance prediction. Previously at the Hydronautics Ship Model Basin he was involved in nearly all aspects of ship hydrodynamics and the development and refinement of test methodologies and equipment. Mr. Sheldon is a 1973 graduate of Webb Institute of Naval Architecture (B.S. naval architecture and marine engineering) a member of ASNE and an associate member of SNAME. He is the author of several published papers concerning ship design and experimental methods.

Key aspects of the design development of a capable yet affordable high performance craft are addressed. These aspects include the development of mission requirements, the rationale for major design decisions, performance capabilities, and system and subsystem selection. The superior performance of the design, as demonstrated by an extensive model test program, led to the decision to develop a family of advanced fast patrol boat concepts. Selected family members are also briefly introduced. The paper, furthermore, demonstrates the successful integration of many major computer-aided design (CAD) programs currently in use for U.S. Navy ship design.

A ship design methodology is presented for developing hull forms that attain improved performance in both seakeeping and resistance. Contrary to traditional practice, the methodology starts with developing a seakeeping-optimized hull form without making concessions to other performance considerations, such as resistance. The seakeeping-optimized hull is then modified to improve other performance characteristics without degrading the seakeeping. Presented is a point-design example produced by this methodology. Merits of the methodology and the point design are assessed on the basis of theoretical calculations and model experiments. This methodology is an integral part of the Hull Form Design System (HFDS) being developed for computer-supported naval ship design. The modularized character of HFDS and its application to hull form development are discussed.
