摘要：
Composite bucket foundation and one-step installation technology for offshore wind turbine are the integration of foundation construction, transportation and whole installation at sea. The cost of offshore wind turbine construction and installation has been largely reduced. Foundation stability is the key technology in the process of towing transportation. Field observation data can reflect the real state of the foundation. In this paper, the influence of water depth and towing speed on liquid level, the compartment pressure, and the pitch angles during towing of composite bucket foundation are studied. These data are analyzed based on the field measurements data from a 3.3 MW offshore wind power project in China. The results show that with varied water depths and towing speeds, the compartment pressure changes are small during the bucket foundation towing process. The offshore wind turbine composite bucket foundation is stable while being towed in the ocean.
