Abstract

PURPOSE: To provide a floating structure on which a wave compelling force is prevented from being exerted, by forming a throttled body being symmetrical about an axis between a water surface and a lower inflated part.
CONSTITUTION: A diameter of a section of an upper floating part 4 at a water surface 3 is D, a diameter of a section of a lower inflated part 1 is D1, a diameter of a section of a throttled part 2 is D2, and they are set to D2<D<D1. A body, being symmetrical about an axis and having a throttled part 1, is formed between the water surface 1 and the lower inflated part 1, and thereby, two wave frequency brings a wave compelling power to a zero, which results in reducing the wave compelling power against a wide range of the wave frequency.
