针对海上风电设备建造的大力发展，依托现有吸力桶导管架的建造项目，对比分析现有海上风电导管架吊装技术难点及共性，根据现有项目要求，创新设计了海上风电吸力桶导管架翻身系统，用于1400t海上风电导管架的翻身竖直工作。文中分析对比了翻身系统与传统吊机的优缺点，采用有限元软件对翻身系统和导管架进行了整体强度和稳性分析；此翻身系统在实际工程中成功应用，翻身50套吸力桶导管架，证明了该翻身系统的可靠性和安全性，为海上风电吸力桶导管架建造安装提供了最新的技术参考。

In response to the rapid development of offshore wind power equipment construction， relying on the existing suction bucket jacket construction project， this paper compares and analyzes the characteristics and performance of existing jacket hoisting technology， and innovatively designs a jacket end-up system according to project requirements， which is used for the vertical work of a 1400t jacket. The article analyzes and compares the advantages and disadvantages of the flipping system with traditional cranes， and uses finite element software to analyze the overall strength and stability of the end-up system. This system has been successfully applied in practical engineering， successfully end-up 50 sets of suction bucket jacket， proving the reliability and safety of the system， and providing the latest technical reference for the construction and installation of offshore wind power suction bucket jacket.
