The Study and Application to Design Methods for Pile Foundation and Jacket Structure of Offshore Wind Turbine

摘要

The design to pile foundation and jacket structure of offshore wind turbine refers to offshore engineering and wind energy engineering.The joint design method combined SACS,a design software for offshore engineering,and BLADED,a wind loads analysis software for wind turbine,is researched in this paper.Moreover,the design technique of the key processes involving primary design,fatigue design and mode analysis is studied.The partial safety factor method and the working stress design method are analyzed in primary design process,the stress time history method based on SACS-BLADED and other fatigue approaches are analyzed in fatigue design process,the method of integrity mode analysis for whole wind turbine assembly is also carried in mode analysis process.As a result,the foregoing method is applied to the design of pile foundation and jacket structure for 6MW offshore wind turbine,and the main parameters of it are represented in this paper.
