DYNAMIC BEHAVIOUR OF A CONTAINER SHIP USING TWO- AND THREE-DIMENSIONAL HYDROELASTICITY ANALYSES

摘要

The symmetric (vertical bending) and antisymmetric (coupled horizontal bending and twisting) dynamic behaviours of a feeder container ship travelling in regular oblique waves are investigated using two- and three-dimensional hydroelasticity theories. Different three-dimensional FE structural models are generated in order to investigate the influence of hatch coamings and on-deck container cargo. Corresponding beam structural idealizations are obtained from these models. Comparisons are carried out between the dynamic characteristics and wave-induced loads predicted by both methods.
