Introduction  With the rapid development of offshore wind power in China, large diameter pile without transition piece has been widely used . This foundation avoids the disadvantage of monopile with transition piece, but result in high demand of construction equipment and the verticality is difficult to control.

  Method  Taking a offshore wind power project in Guangdong as an example, the key technologies of pile driving construction for monopile without transition piece were comprehensively expounded in this paper.

  Result  The construction plan of monopile driving is being proven high efficiency, safety, reliability, and cost-effectiveness.

  Conclusion  Key technologie of pile driving construction for monopile has certain guiding significance for similar projects.
