Sažetak
The main results of structural analysis of livestock carrier designed in ULJANIK shipyard (Yard no.486-487) have been presented. The most important aspects in a rational structural design of this kind of ships have been underline. The ship structure is characterized with large openings in superstructure side shell and with the absence of transverse bulkheads in superstructure part (zone above Deck 6). Ventilations tubes (channels) are integral and the load carrying part of the structure. Two main structural problems have been evaluated: (1) longitudinal strength, with the appropriate level of superstructure participation in 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 identified and longitudinal stress distribution over ship height has been given for the prototype and the proposed model. Critical locations (where a fine mesh FE analysis is needed) with the high stress concentrations have been indentified. Gain in structural weight has been achieved in the superstructure due to the rational redesign procedure.
