Abstract: The installation of offshore wind turbine monopile foundation requires a variety of ship machinery and lifting equipment, etc. If the suitabe selection of those above matters could make the completion of the construction objectives be achieved. In order to select suitable ship machinery lifting equipment, using project as example the compare between domestic and foreign monopile installation, the selection consideration of the main floating crane ship and the drivability of the hydraulic hammer are specifically analyzed through the verification analysis of the monopile stabilizing platform and the description of other additional installation points, which shows that the main considerations for the selection of marine machinery and lifting equipment for offshore wind turbine monopile installation in China and the verification analysis methods are useful. These can provide serve as for the selection of marine floating machine for monopile installation, for the design and verification of monopile stabilizing platform, and for the preparation of construction organization and scheme.

Key words: offshore wind power, monopile foundation installation, the monopile stabilizing platform
