Research on Pre-assembly Technology of Offshore Wind Turbine Tower

Taking the 350 MW offshore wind power project in Jin Ou, Vietnam as an example, this paper deeply analyzes the pre-assembly technology of offshore wind turbine tower, aiming to improve the efficiency and safety of the project. The research focuses on pre-assembly process planning, covering equipment storage, tooling and raincover design, emphasizing the customization of split tower tooling, efficient use strategy and precise lifting technology to ensure accurate and efficient operation. At the same time, we attach importance to quality control and environmental protection measures to ensure the quality and safety of operations and reduce environmental impact. This paper summarizes the advantages of pre-assembly technology and its application prospects in promoting the sustainable development of offshore wind power industry, and provides solid technical support and reference for practice.
