Abstract

Aiming at the complex and bad environment of offshore energy development, this paper proposes a six-bucket foundation structure that can be used for self-floating towing. The model test method is used to explore the influence of towing speed and draft on the response of the towing motion for bucket foundation during the towing process. The results show that, with the increase of towing speed, the change of the cabin pressure of the foundation increases. In the actual towing process, attention should be paid to the air supply and leveling of the tanks with large tank pressurechange to ensure sufficient towing stability. The roll angle of the floatation process at different speeds and draughts fluctuates within 3°. The towline force is significantly affected by the speed and draught. Under the same draught, when the towing speed increases from 0.3 m/s to 0.4 m/s, the average value of the towing resistance is approximately doubled.

Key words
