Shipbuilding industry is undergoing a change, in which many European shipyards focus on special purpose vessels. This field of shipbuilding places very high demands on engineering, commissioning and operation of the vessels. To support these fields of activity with virtual methods an innovative approach is introduced which strengthens the shipbuilding process by using a uniform common model of the overall system ship. The model is steadily increasing and gets more detailed through the phases of the shipbuilding. The presented approach fills the gap in the virtual support of the complete shipbuilding process, taking into account the specific structural needs -short time, high cost pressure and high quality demands.

a) b) c) Fig. 1. Generic ship model: a) meshed FEKO model, b) detail of 3D plotted scaled ABS polymer ship model and c) detail of galvanized ship model with scaling factor of 1/200 th .ABSTRACT -A new scaling technique for experimental investigations of naval fan-wire antennas based on highly accurate electroplated plastics ship models is presented. Using a 3D plotter the ship model is made of ABS polymer. Due to the high resolution of this technique of 0.12 mm a scaling factor of 1/200 th instead of commonly used scaling factors of 1/48 th or 1/50 th for scale brass models can be used with sufficient accuracy. Hence, the scaled frequency range and the dimensions of the model are appropriate for standard microwave anechoic chambers. Furthermore, production time and costs were cut by more than 90%.
