Linear characteristics of the sloshing phenomenon for the purpose of on-board ship's stability assessment

The paper presents results of experimental research and numerical simulations of the sloshing phenomenon. The research was focused on computation of the heeling moment affecting stability of a vessel. The proposed linearisation enables application of the results to the assessment of the ship's stability. The dependence of the heeling moment upon localisation of a tank in the ship's hull is analysed. The heeling moment obtained in the course of the research was compared to the moment computed in accordance with the Intact Stability Code requirements. The study may be a contribution to the more sophisticated estimation of the ship's stability than it is achieved nowadays.
