Pile Driving Construction Process and Application of Offshore Wind Turbine Monopile Foundation

Abstract

[Introduction] Offshore wind power generation is gradually being widely applied in the global energy structure transformation due to its advantages of high annual power generation and stable power generation. However, due to the complex and ever-changing marine environment for offshore wind turbine construction, this poses significant obstacles to the construction process and technical solutions of offshore wind turbine foundations. [Method] In the context of the construction project of a certain offshore wind farm, this paper analyzed the type selection criteria and feasibility of pile driving construction ships, pile stabilizing platforms and hydraulic pile hammers. At the same time, in response to the construction requirements for wind turbine foundation pile driving, the preparation work before the operation, the construction plan for the pile stabilizing platform, and the wind turbine foundation pile driving operation with the cooperation of the main-auxiliary crane ships were emphasized. Furthermore, the control and correction measures for verticality in wind turbine foundation pile driving were analyzed. [Result] Steel pipe pile driving construction process can effectively ensure the project quality and expected progress, and has significant economic benefits, safety and reliability. During the pile driving process, it's necessary to complete preliminary and final adjustments to the verticality accural control. [Conclusion] Through the study of pile driving construction technology for offshore wind turbine foundations, it will provide useful reference and inspiration for similar offshore wind turbine projects.
