Case Studies in Structural Design and Optimization

Case studies in structural design and optimization show, using ships built or designed in Croatia, that structural optimization is a mature tool offering significant savings to the shipyard : decrease in price of construction steel and weight, increase of deadweight, fast calculation of the most complex ships, obtaining of special class (by e.g BV )which assume 3-D FEM model. Full ship 3D FEM modeling permits response, safety evaluation, optimization, vibration analysis to be performed on a single FEM model. Modeling with large macroelemets (stiffened panel, bracketed beam, double wall element) allows fast development of the model. The models of large passenger and car/passenger ships, product carrier,double wall tanker and reefer/ro-ro ship are used to demonstrate those benefits.
