The suction bucket foundation is turning to be an increasingly prevalent foundation for offshore wind turbines (OWTs). In this study, a series of centrifuge tests are performed to investigate the vertical bearing capacity of the suction bucket foundation in sandy soil under drained condition. Four bucket models are tested by considering the influen...
Article
Some large capacity offshore wind turbines are constructed in seismically active areas. The occurrence of soil liquefaction during an earthquake can result in severe failures of the offshore wind turbine. The seismic response of the structure and the failure mechanism of the soil-structure interactions are necessary to investigate. In this study, t...
Article
Suction bucket foundations are promising foundation options for offshore wind turbines, which are usually subjected to a relative high lateral-moment loading. To investigate the lateral-moment loading capacity of bucket foundations, a group of three-dimensional finiteelement simulations with different bucket dimensions in both loose and dense satur...

... For water depth of more than 30 m, the jacket foundation is always recommended [2][3][4]. The jacket with multi-caissons has great conveniences in transportation and installation, becoming a popular foundation form for OWTs [5]. ...
... With the rapid application of bucket foundations for OWT, numerous studies have focused on the seismic response of bucket foundations. Yu et al. [23], Wang et al. [24], 2 of 23 Olalo et al. [25], Wang et al. [26], Wang et al. [27], Li et al. [28] and Zayed et al. [29] conducted studies to investigate the factors influencing the seismic response of bucket foundations through centrifuge shaking table tests. Asheghabadi et al. [30], Gao et al. [31], Gao et al. [13], Wang et al. [32] and Zayed et al. [29] studied the seismic response of bucket foundations in liquefiable seabeds via numerical analysis, focusing on the influence of bucket foundations' depth-to-diameter ratio, sand density, soil permeability and earthquake magnitudes. ...
... A number of physical model tests [11][12][13][14][15][16][17][18][19][20][21][22], analytical calculations [23][24][25][26] and numerical analysis [27][28][29][30][31][32] were carried out to investigate the lateral -moment bearing capacity of bucket foundations in sand. Achmus et al. [28] investigated the lateral -moment bearing capacity of bucket foundations under monotonic lateral loading in medium dense sand (33% ≤ D r < 67%, where D r is the relative density of sand) and dense sand (67% ≤ D r < 100%) through 3D finite element (FE) analysis. ...
