Wave Forces on the Composite Bucket Foundation of Offshore Wind Turbines

Applied Mechanics and Materials, 2013
A three dimensional numerical model to calculate the wave forces on the composite bucket foundation of the offshore wind turbine is established and the analytical method to approximatively calculate wave forces on the structure with the variable cross section is proposed. Based on the validation of numerical results, wave forces on the composite bucket

Study on Effects of the Scouring on Horizontal Bearing Capacity of the Composite Bucket Foundation

Volume 10: Ocean Renewable Energy, 2018
Composite bucket foundation is a new kind of wide-shallow foundation for offshore wind turbines, and can be made on land, transported and installed by one step. Compared with other deep pile foundations, the erosion caused by waves and currents is more obvious and this would cause more risks for the overall safety of the wind turbine.

Anti-liquefaction characteristics of composite bucket foundations for offshore wind turbines

Journal of Renewable and Sustainable Energy, 2014
Occurrence of liquefaction in saturated sandy deposits under structure foundation can cause a wide range of structural damages from minor settlement to general failure because of bearing capacity loss. By comparing traditional foundations for offshore wind turbines, the soil inside and underneath the composite bucket foundation is subjected to the ...

Force transfer characteristics of composite bucket foundation for offshore wind turbines

Journal of Renewable and Sustainable Energy, 2016
This paper presents a new type of composite bucket foundation (CBF) for offshore wind turbines, which can be adapted to the loading characteristics and development needs of offshore wind farms due to its special structural form. There are seven rooms divided inside the CBF by steel bulkheads, which are arranged in a honeycomb structure.

Bearing capacity and technical advantages of composite bucket foundation of offshore wind turbines

Transactions of Tianjin University, 2011
Based on mechanical characteristics such as large vertical load, large horizontal load, large bending moment and complex geological conditions, a large scale composite bucket foundation (CBF) is put forward. Both the theoretical analysis and numerical simulation are employed to study the bearing capacity of CBF and the relationship between loads and ...

Bearing capacity of composite bucket foundations for offshore wind turbines in silty sand

Ocean Engineering, 2018
Abstract A composite bucket foundation (CBF) with seven compartments arranged in a similar honeycomb structure is a relatively new type of structure for offshore wind turbines. Field tests were conducted at a natural water pool with a water depth of 0.4 m in saturated silty sand off the coast of Jiangsu to estimate the horizontal bearing capacity of ...
