Abstract
PURPOSE: To prevent vibration at an after-peak and prevent damage of the stern part due to resonance, by forming openings, on the floor in the after-peak in addition to the manhole, and reducing the added mass of water so as to increase its proper frequency.
CONSTITUTION: On the floor 2 in an after-peak A, a number of openings 6 are formed, in addition to the manhole 4, so as to increase the rate of opening of the floor, and the added mass of the water is reduced, in order to increase its proper frequency. Thus, the vibration at the after-peak A can be prevented, so that the damage of the stern part due to resonance may be avoided.
