Sažetak
Optimization of RoPax ship structural design is presented. Sensitivity analysis of structural weight with respect to web frame spacings of 2400, 2800 and 3000 mm was performed. Three models (12 web frame spacings long), dominating ship structure, were used. Program MAESTRO was used for minimal weight optimization of each model. Designer identified 264 design variables and has specified min-max and proportionality requirements. Each 3D FEM model includes 5850 degres of freedom. Models are capable of solving nonsymetric loadcases. 1067 macroelements and 212 ordinary elements were modeled for response calculation. 7 loadcases were defined according to DnV and designers requests. 52416 safety checks were performed on each model. Significant savings to the shipyard have been obtained: decrease in price of construction steel and weight (up to 10%), increase of deadweight, improvement of design (decrease of ship height), etc. Results show that structural optimization is a mature designers tool.
