Abstract

A method for installation of an offshore wind turbine. The method includes prefabrication of a foundation that provides buoyant force and uprighting force to the foundation so as to keep it upright without external forces. The method further includes installation on a dock that includes assembling the offshore wind turbine into a complete set, and finishing testing in a state of the complete set. The method further includes transporting the complete set to an offshore site in a way of floating on the water, and then offshore installation that includes sinking the complete set onto a sea bed by gravity on the offshore site, and fixing the foundation to finish the installation. The present invention also provides a method for recovery of an offshore wind turbine, which is performed generally in steps reversed to the method for installation.
