In inland reservoirs and lakes， the integral removal technology of wind turbines is currently blank in China， As the conventional technology and equipment used for offshore wind turbine disassembly cannot be used. in order to solve the problem of Goldwind Technology produced 2.5WM wind turbine removal in Guanting Reservoir， a float platform assembled by some pontoons at temporary wharf， the temporary wharf built by dredging on the shore， the single pontoon is prefabricated in the factory and the transport to wharf where assembled one by one to form a floating platform. The floatover integral removal technology applied in extremely shallow water depth， which improves construction safety， saves materials and construction time， and is convenient for demolition. This paper introduces the design idea and engineering practice of integral removal of wind turbine by floatover method， hopes can provide reference for similar projects.
