Abstract

<p> The effectiveness of flume-type anti-oscillation tanks against the motion of a floating caisson under regular, unidirectional irregular, and multi-directional irregular waves was investigated using hydraulic experiments. From experimental results, it was found that the non-dimensional total amplitude of the pitch was reduced with an increase in the mass of free water filled in the anti-oscillation tanks. Moreover, the non-dimensional total amplitude of the roll was reduced by loading free water and could be increased by loading additional free water. This suggested that there can be an effective mass of free water in each anti-oscillation tank in the surge and sway directions.</p>
