PURPOSE:To absorb the vibration of the hull without any special dynamic damper by making the structure of the bottom of a cargo hold partitioned and supported by both sides of a vessel and lateral fore and aft bulkheads possess a nutural frequency of vertical flexing that can dynamically absorb the vibration relative to the frequency of a vibration source. CONSTITUTION:The structure of the bottom of a central cargo hold which is partitioned and supported by both sides 10a, 10b of a vessel and fore and aft lateral bulkheads 11a, 11b is made to possess a natural frequency of vertical flexing that can dynamically absorb the vibration relative to a frequency of a vibration source such as the rotation of the propelling device at the stern. In this manner, without providing any special dynamic damper such as flexing member and airtight chamber, the absorption of the vibration of the hull can be effectively achieved.
