Abstract
ABSTRACTThis paper presents a surface ship hull form design methodology which makes use of a powerful, general‐purpose approach to decision making. The four steps of this approach are:1. Development of the Problem Statement2. Design3. Evaluation4. SelectionTo illustrate the utilization of the methodology, the development of the hull form during the Concept Design phase of a new U.S. Navy surface combatant is described. The development of the problem statement from the given requirements, constraints, and design standards is discussed. The design of three alternative hull forms is detailed. Each hull form was optimized, within the design constraints, to a separate and distinct hydrodynamic performance goal. These goals were optimum seakeeping performance, minimum cruise speed resistance, and minimum high speed resistance. The performance of each alternate hull form was assessed, as well as that of a baseline hull form. A rigorous evaluation of the alternative hull forms is presented and the selection procedure described. Conclusions are presented regarding the methodology and the “worth” of the alternative designs.
