【 摘 要 】

This scientific research presents very important aspects of the liquefying process of bulk cargo carried on board merchant ship which may lead to loss of the intact stability of bulk carriers, with serious consequences for the safety of ships and their crew. We are going to present an analytical modelling, modal analysis and finite elements analysis applied in the hydrodynamics of the ship in the water environment, when realising a complex model 3D of the ship's bulkheads by modelling with finite volumes with the purpose of emphasising these walls' behaviour when on board the bulk carrier there is a sloshing effect due to free liquid surfaces in the ship's cargo holds and we also performed a complex study regarding the structural answer of transverse bulkheads of the cargo holds due to the impact of free liquid surfaces.
