摘要：
The external force loads on offshore wind turbines are complex. Considering the coupling effects among all external loads is crucial for obtaining more accurate dynamic responses,such as internal forces and deformations,and is also an important means to reduce the cost of offshore wind power generation. By comparing and analyzing the differences between the separated design and integrated design based on the monopile foundation of a certain offshore wind power project in Zhejiang Province,it was found that the separated design lacks consistency in wind and wave loads over time,repeats the partial inertial effects caused by wave action,and has more conservative provisions on load correlation coefficients than the integrated design. The integrated design is superior to the separated design in both ultimate and fatigue analyses,and can greatly reduce the cost of offshore wind turbine foundations. © 2024 Science Press.
