Abstract

The air flotation characteristics are a key aspect of bucket foundations. However, the mooring mechanism for this type of foundation during air-floating is not well understood. In this paper, model tests were conducted to analyze the taut mooring characteristics of a four-bucket foundation as a floating wind turbine foundation. The effects of draft depth, water depth, and anchorage distance on the motion response of the model were investigated. Our findings are as follows： the structure exhibits wave frequency motion in short periods and slow drift motion in large periods. As the draft increases, the heave motion shows an opposite trend to surge and pitch motion. The shallow water effect causes greater heave motion in shallow depths compared to deeper depths. Increasing the anchorage distance can mitigate the impact of slow drift on surge motion, but it increases the heave and pitch motion of the structure.
