FE based structural optimization according to IACS CRS-BC

According to IACS CSR for Bulk Carriers, a direct strength analysis based on the three hold FE model of the cargo area is mandatory for all vessels above 150 m in length. Structural design according to those requirements is a challenging task that demands utilization of the integrated design system. To allow the designer to fully realize all benefits of the formal optimization procedure, an in-house structural design support system OCTOPUS-CSR was developed for concept and pre-liminary design phases. The developed design system was used for the structural design of the bulk carrier series to be built in ULJANIK Group shipyard 3.MAJ and the main achievements in the preliminary design phase are presented in this paper. Developed tools and methodology provides the shipyard and the ship-owner with the possibility of fully controlling structural scantlings while following the basic paradigm: lower ship production cost for the shipyard and a more profitable and durable ship for the ship-owner.
