Sažetak
Prototype design of the wagon (tank car) carrier structure according to minimal scantling requirements of Russian Maritime Register of Shipping Rules (RS), designed by the ULJANIK Shipyard, is presented. To analyze realistic 3-D effects the full ship (coarse-mesh symmetric) 3-D FE model was developed. It simultaneously gave insight into all relevant critical areas especially regarding hull-superstructure interaction in sagging/hogging condition and racking forces. Five load cases, based upon T&S Book and RS Rules, were generated. The effectiveness of the very long superstructure (approximately 0.45 L) in longitudinal strength is discussed. Critical areas were identified in global model regarding: (a) deformations of accommodation and upper decks, (b) stress concentrations in superstructure openings and at its ends (c) buckling in shell plating amidships, etc. Optimization model was developed to minimize weight additions above minimal scantlings to satisfy structural requirements of RS and deck rigidity regarding deck deformations in wagon area. Based upon optimised dimensions, the structural modifications were inserted in full collaboration with the designer.
