Abstract

The large composite bucket foundation (LCBF) was used for the first offshore wind turbine in Qidong sea area of Jiangsu Province in China. The most critical technique of the foundation is self-floating towing technique based on a reasonable subdivision inside the bucket. In order to predict the dynamic behaviours of aircushion supported the LCBF in waves, the hydrodynamic software MOSES is used to simulate the three-dimensional motion of the foundation in towing construction site. The floating technique of the LCBF with supported aircushions in waves is highly competitive for saving lots of cost with few expensive types of equipment during the towing transportation.
