“…Driven by the rapid development of offshore wind farms, bucket foundations have come to constitute a very promising form of foundation for offshore wind turbines [8]. In recent years, the suction bucket, a novel kind of foundation that is quicker to install and significantly lowers building costs, has gained popularity in the field of marine engineering both domestically and internationally [9,10]. Figure 1 illustrates the steel "mono-column + connection + bucket" overall structure of the mono-column composite bucket foundation (MCCBF) [11,12], which fully utilizes the benefits of the bucket and monopile foundation structure through the connection structure.…”

To address the issue of seepage and soil plugging during the sinking of mono-column composite bucket foundations (MCCBFs), experiments were conducted on the installation of foundations under a variety of complex geological conditions. The effect of negative pressure sinking mode on the foundation’s seepage field was analyzed, the formation mechanism of soil plugging in sand was explained, and an efficient method for calculating the height of soil plugging was proposed in conjunction with these investigations. The findings demonstrate that the finite element method simulation of the soil’s seepage field is the most accurate, that the pumping volume of the foundation during sinking through is high, that the formation of the soil plug height is high, and that clear depressions can be seen on the foundation manifold’s exterior. The equation presented in this study makes it easier to forecast the height of a foundation plug and can offer direction for engineering design.

“…Therefore, the study of mooring-line failure is necessary. Mooring-line failure has been studied on offshore oil and gas floating structures [28][29][30], and in recent years, with the rise of FOWTs, scholars have also become interested in their mooring-line failure problems [31][32][33][34][35]. Bae et al [25] studied the effects of mooring-line failure on the steady and dynamic responses of the OC4 DeepCwind semi-submersible FOWT, as well as the tension in the remaining mooring lines and turbine performance, by disconnecting one of the three mooring lines.…”

Evidence points to increasing the development of floating wind turbines to unlock the full potential of worldwide wind-energy generation. Barge-type floating wind turbines are of interest because of their shallow draft, structural simplicity, and moonpool-damping effect. Based on the BEM potential flow method, this study uses ANSYS-AQWA software to create a floating-barge moonpool platform model equipped with an OC5 NREL 5 MW wind turbine, to study the effect of the damping lid method on the resonance of the moonpool gap water, the wind–wave coupling effect, and the dynamic response of the FOWT and mooring system after single-line and double-line failure. The results show that the damping lid method, based on the potential flow theory, can effectively correct the effect caused by the lack of viscosity; the effect of a single breakage of upwind mooring lines on the motion is mainly in the sway and yaw modes, and after mooring line 8 breaks, the maximum tension of the adjacent mooring line increases by 2.91 times compared to the intact condition, which is 58.9% of the minimum breaking strength; and the breakage of two mooring lines located at one corner leads to a surge drift of up to 436.7 m and a cascading failure phenomenon.
