The author points out that the preliminary ship design process is a natural for design automation as it involves an iterative series of calculations based upon a data base which describes the hull shape. At the Maritime Administration, the automation of the design process started some time ago with the creation of batch programs for each step in the design sequence. The programs which require direct access to the hull form data base form the Hull Scientific Package and consist of five programs: Bonjeans/Hydrostatics (hull characteristics of volume, centers and areas), Floodable Length (compartment length required to prevent sinking when flooded), Longitudinal Strength (bending moment and shear forces on the ship when loaded), Capacities (tankage volume and centers), and Damage Stability (ability to survive in a damaged condition). Other programs in the sequence rely on a data obtained from the Hull Package but do not access the hull form data base. While these programs were computationally efficient they suffered on both the input and output sides. The addition of interactive creation of inputs files, a digitizer, and a plotter for graphical output have since been added to give the total system a new dimension. In order to better describes the system's capability, a sample design is developed explaining the role of each program in the design sequence.
