Modelling assumptions when idealising the structure of mono-hulled vessels may have an effect on the predicted wave-induced loads, when using fluid-flexible structure interaction (FFSI) models. The aim of this paper is to demonstrate the influence of structural modelling on the dynamic behaviour of a bulker in waves, a ship structure with large deck openings. Three idealisations are used, namely the original bulker with all relevant deck openings, and the open and closed ship configurations where the deck structure between deck openings is ignored and plated over, respectively. Two- and three-dimensional hydroelasticity analyses are applied for each configuration and model. Dry hull natural frequencies, mode shapes and steady state wave-induced loads, such as vertical and horizontal bending moments and twisting moment, in regular waves are presented and discussed for all configurations. It is shown that the major influence of the structural modelling occurs in the antisymmetric dynamic behaviour of this vessel.
