Abstract : Much attention has been given in recent years to the problem of reducing ship construction costs. Efforts have primarily focused on the improvement of production techniques, processes, and management controls. However, there is a great deal more that can be accomplished in reducing ship construction costs by improving the producibility of a ship's design. The design of a more producible ship requires concurrent product and process design. Various principles and techniques can be applied throughout the design process to reduce the construction manhours required by ensuring that manufacturing attributes are considered. This paper is a description of the producibility principles that should be applied in the design of any ship to minimize construction costs. The application of these principles requires a team effort with the coordinated experience and knowledge of the ship designer, production engineer, and production planner focused on the problem of reducing costs. A practical approach to estimating the cost benefit of alternative designs by estimating the labor input differential between the designs is presented. The paper also includes specific examples of the application of producibility techniques to several recent ship designs. The paper discusses limiting capability, double curvature, hull curvature, frame spacing, unit breaks, limiting unit size, knuckles, standardized parts, machinery arrangement, machinery units, welding, weight versus cost, estimating costs, and comparative cost estimates.
