AN INTEGRATED SYSTEM FOR THE BASIC DESIGN OF SHIP STRUCTURE

Ship structural design information which conventionally has been transferred through various drawings and documents is integrated in a database system. In order to represent the semantics of ship structural elements, an entity - relationship model was used. For the logical data model a relational model was used. Users who are involved in ship structural design can share the information in the database, so they can reduce much of the redundant work and input errors that might otherwise occur. The system consists of three major parts; 1) Ship structural design system which performs the structural arrangement and scantling definition, 2) Structural analysis system which performs automatic FEM modelling and analysis, 3) Vibration analysis system which calculates the hull girder vibration characteristics.
