Due to the lateral stiffness shortage of the monopile, and in order to improve the applicability of the monopile, a new wind turbine foundation type which is combining the jacket and monopile foundations is proposed. Based on the engineering example of offshore wind farm in Fujian Province, China, the main design parameters are considered. A 5 MW wind turbine foundation finite element model is established as the research object. Compared the results of monopile and the new composite foundation, conclusions are obtained. These findings will provide some reference for the new type foundation design.
