Concept and Preliminary Structural Design Methods for the Modern Multi-Deck Ships

The paper covers the multi-criteria design methods for the practical structural design of the multi-deck ship structures such as Ro-Pax, Ro-Ro, Car carriers, Livestock carriers, Tank-car carriers, Con-Ro ships, Cruise and Passenger ships. Approach combines the fast generation of design variants using the 2.5D transverse strip FEM models and the generic 3D-FEM models (based on macro-elements) into two step decision support procedure based on the topology and scantling optimization. In the concept design phase objectives considered, besides cost and weight, may be the ultimate longitudinal strength safety measure and the system reliability measure in racking mode. Practical implementation of the Decision Support Methodology is presented using (1) the ISSC 2006 benchmark structure of the cruise ship for topology/scantling optimization and (2) the RoPax ship for the reliability based concept design.
