Sažetak
For multi-deck ships with extensive superstructures (such as passenger ships, RoPax, etc.)the global structural response can be particularly complex. The influence of the superstructure to the primary strength for those multi-deck ships has to be taken into account from an early design phase.Main global topological parameters (e.g. size of side openings, stiffness of longitudinal bulkhead, etc.)have dominant influence on the shape of hull girder stress distributions over the ship height. The Taguchiconcepts and techniques (FFE, orthogonal arrays, ANOVA, etc.) could be used to systematically study influence of multiple topological parameters on the global structural response obtained by FEM analysis. It also enables rational identification of the most dominant parameters and provide designer with the near-optimal level of each topological parameter. It has been demonstrated, using simplified model ofpassenger ship as an example, how different topological variants can lead to different optimal structural scantlings w.r.t chosen design objectives (mass, VCG, etc.)
