Abstract

As the key structure of offshore wind farm, offshore substation must ensure the safety of structure under earthquake. According to previous studies, the influence of pile-soil interaction on the dynamic response analysis of offshore platform structure under earthquake is particularly significant. In this study, an offshore substation located in a high seismic intensity area in China is taken as the research object, a refined FEM model considering pile-soil interaction is established based on the method of API Recommendation, and the structural safety under earthquake action is checked. The results show that the offshore substation structure meets the requirements of seismic fortification, and the structure is obviously affected by vertical earthquake.
