Basic understanding of ship structures and hull strength and use of FE analyses for strength calculations. Knowledge in Nauticus Hull as covered in NA-02. It is beneficial if the participants have attended SE-01.
NA-07 Nauticus Hull cargo hold analysis FE - CSR bulk
The course is an introduction to programs for modelling and FE analyses of bulk carriers in accordance with the IACS Common Structural Rules for Bulk Carriers (CSR Bulk).
Focus is put on extruding a cross section from Section Scantling, then 3D modelling of a cargo hold model and mesh control in Sesam GeniE, applying loads, corrosion additions and boundary conditions according to the CSR Bulk rules, running a FE analysis and post-processing using Xtract. Yield and buckling strength checks according to CSR Bulk are covered.
The course will be a combination of lectures and hands-on training. The hands-on example consists of building a cargo hold model, analysing it and perform buckling and stress level assessment. The cross section for the cargo hold model is extruded from a midship section modelled in Section Scantlings in the NA-02 Nauticus Hull Rule Check analysis course.
The course will also provide a presentation of the IACS Common Structural Rules for Bulk Carriers and their requirements to strength assessment analyses of the cargo hold area.
After the course you should be able to use Nauticus Hull and Sesam GeniE for cargo hold modelling and execute FE analyses for buckling control and strength and stress level assessment according to the CSR Bulk rules.
Naval architects, designers, hull structural engineers and approval engineers with no or limited experience using Nauticus Hull for the Common Structural Rules for bulk carriers.
