Kriging analysis on CPTU data from offshore wind farm

Abstract

In recent years, offshore wind power has been widely developed. Because of the com plexity of marine geology and the large spatial variability of soils, it is necessary to obtain CPTU data before the foundation design. However, how to reasonably interpret the CPTU data will greatly affect the reliability and safety of the offshore windfarm foundation. In addition, there is a need to predict soil conditions at the locations without CPTU data. In this study, based on the available CPTU data of offshore wind farm in east China sea, kriging method is used to interpret the CPTU data, and the soil conditions in a large area can be predicted. This method can be used to develop ground model for a large offshore wind farm, and estimate the relevant soil parameters based on CPTU data. The analysis methods can provide reference for other projects of offshore wind farm.
