The study aims to provide a realistic reference for the offshore wind energy industry in China by comparing and recommending soil parameters for foundation design based on laboratory tests, as there are limited advanced tests available for windfarm development in the area.
The Zhuanghe wind farm is under development offshore China. The site investigation campaign was completed in 2019. Both monopiles and suction buckets are considered as foundation types, and they are presently in the design phase. Soil testing was carried out at both the HDEC and the NGI laboratories. Soil parameters obtained from the laboratory tests are interpreted and discussed in this paper. Important soil parameters for foundation design, such as static and cyclic shear strengths, shear modulus and thixotropy from the tests on the Zhuanghe soil are compared with available databases in the literature, and soil parameters for foundation design are recommended. The purpose of this study is to provide a realistic reference for research and practice in the offshore wind energy industry offshore China where very few advanced tests for windfarm development are available.
