Strength Design of Offshore Wind Turbine Foundation

Considering the environment differences between onshore and offshore wind turbines,integrating all of loads-wave and flow and so on-that wind turbine was suffered,this paper presented a method estimating the strength of offshore wind turbine foundation.Based on multi-body dynamics,an entire set model of the turbine was set up by finite element method,the loads on the turbine were calculated,to check the structure strength of the foundation by API standard.According to the results,we could optimize or redesign the foundation,and make sure it was ok for all of loads.In the last,the paper gave an example to show the process of analysis.
