Abstract
<p> The effectiveness of flume-type anti-oscillation tanks installed on a floating caisson in the pitch and roll directions under regular waves and multi-directional irregular waves was investigated from hydraulic experiments, and a simple numerical method for estimating the effect of the anti-oscillation tanks was developed and applied to the hydraulic experiments. From experimental results, it was revealed that the anti-oscillation tanks can reduce the pitch of the caisson increased at around the natural frequency and its double frequency under the regular waves. Furthermore, the anti-oscillation tanks were found to be effective against not only the pitch but also the roll under the multi-directional irregular waves. From numerical results, it was found that the effect of the anti-oscillation tanks can be estimated reasonably well in terms of the amplitude of the pitch. This suggested the usefulness of the developed method in estimating the most effective water volume in anti-oscillation tanks.</p>
