On the Effect of Anti-Rolling Tank to a Gust of Wind

Abstract

Throughout this experiment we try to examine the effect of an anti-rolling tank when a ship is under the condition of steady wind, having 1.5 time's wind pressure of the steady wind at the maximum angle of roll windward. By using dynamical stability curve, we confirm that this anti-rolling tank is not sufficiently effective for a gust of wind and that the calculated value approximately agrees with the experimental value of rolling angle for a gust of wind.
