| Abstract: | Particularity of structural design is determined by feature of general arrangement. The calculation methods of global hull girder loads and section modulus applying membrane stress criterion are described. Sloshing pressures and areas to be assessed are shown, the principle is discussed. The extent of FE models and loading conditions to evaluate strength of fore and aft cargo holds are shown. Based on finite element analysis, conclusions are made about the prominent problems and solutions. |
