Abstract

Robust Design Optimization (RDO) to support structure of offshore wind turbines which decreases the cost and its variations considering uncertainties is discussed in this study. Firstly, an approximate model utilized with Design of Experiment (DOE) is introduced to replace the time consuming computational dynamic response analysis of FE model for saving the computational cost. Then, a Deterministic Optimization (DO) without considering the uncertainties is induced for comparison. The results provide the feasibility and efficiency of the whole framework of RDO method, which can be a reference for the design of other offshore supporting structures.
