| Abstract: | Taking a tetrapod bucket foundation as the research object, the factors influencing the motion characteristics of the structure during air-floating are investigated by model tests in still water and regular waves. The results indicate that the added mass coefficient of oscillating motion decreases with the increase of draft, which is greater than the recommended value 1.2 in ship dynamics. As the draft increases, the heaving motion first decreases and then increases, while the pitching motion decreases. The vertical motions of the structure are enhanced in shallower water. However, the change trend of maximum amplitude of heaving motion is opposite to that of pitching motion with the change of water depth. The optimal motion responses of the structure are achieved at 4.5 m draft and 12.5 m water depth. |
