The dynamical effect of a free water surface in on open tank with a rectangular section is investigated considering the effect of the surface waves occurring in the tank.
The results of the theoretical calculation show that the dynamical influences are large when :
1. the tank is located upwards.
2. the natural frequency of the ship is large.
It may also be certain that the rolling motion caused by an exciting moment having a frequency coinciding with the natural frequency of the tank water becomes extinct in short time.
