The main results of the structural analysis of large livestock carrier have been presented. The most important aspects in the rational structural design of this kind of ships have been underlined. The ship structure is characterized with large openings in the superstructure side shell and with the absence of transverse bulkheads in superstructure part (zone above Deck 6). Ventilations tubes (channels) are integral load carrying part of the structure. Two main structural problems have been evaluated: (1) longitudinal strength, with the appropriate level of superstructure participation in the hull girder bending; (2) transverse/racking strength, where the capability of transverse structure has been evaluated. The strength calculation has been carried out according to RINA Rules using FE coarse mesh approach. Superstructure participation in hull girder longitudinal bending has been evaluated and longitudinal stress distribution over ship height has been analyzed for the prototype and the proposed model. Critical locations (where a fine mesh FE analysis is needed) with the high stress concentrations have been identified. Gain in structural weight has been achieved in the superstructure due to the rational redesign procedure.
