A spherical tank designed to withstand the loads that can ocur when the tank is only partly filled has several operational advantages. However, no reliable theory is yet available for predicting the sloshing loads in a partly-filled tank, and the most reliable way of estimating them appears to be to use the results of model experiments. The Author, of Det Norske Veritas, presents and discusses data based, mostly, on forces measured during model tests; the forces were recorded at different periods of oscillation for selected combinations of fill depth and excitation amplitude. Only harmonic tank-oscillations are considered and the forces presented do not, there fore, give a correct picture of what can be expected in a spherical tank under realistic ship-motions. Nevertheless, from these data a reasonable prediction could be made of the magnitude of the dynamic forces under given sea conditions for a full-size ship.
