BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an offshore wind turbine installation apparatus and an offshore wind turbine installation line including the same, and more particularly, to an offshore wind turbine installation apparatus capable of smoothly and efficiently performing an assembly and installation work of an offshore wind turbine generator The present invention relates to an offshore wind turbine installation line.

As the demand for environmentally friendly energy development grows, the development using wind power generators is getting popular all over the world. In order to install such a wind turbine, a certain environmental condition is required. For example, a place where a wind turbine is installed must be a place where a certain level of wind speed can be ensured for the blade of the wind turbine to generate rotation, It should be a place where pollution caused by noise generated during driving should not be an issue. Even if these environmental conditions are satisfied, a very large area of space is required to install a wind turbine generator.

In recent years, there has been an increasing interest in offshore wind turbines that install wind turbines at sea, in order to be free from the constraints of such environmental conditions. Offshore wind power generators typically include towers, generators bodies and blades, which can be manufactured and transported onshore and assembled and installed together at sea, or assembled offshore wind turbine generators And then transporting them to sea and performing installation work at sea is being used.

However, when the components are transported by sea and assembled and installed together, the assembling work and the installation work must be performed sequentially. Therefore, the period of the process is long and a lot of manpower is required. In particular, The structure becomes complicated and the efficiency of the operation is deteriorated.

On the contrary, if all of assembly work of offshore wind turbine is performed on the land and then it is transported by sea, only the offshore wind turbine is very large and its appearance is complex, so that a large amount of offshore wind turbine generator There is a problem that the efficiency of transportation is deteriorated. In particular, when loading and transporting an assembled offshore wind turbine generator in a standing state, the load on the blade of the offshore wind turbine generator is liable to be caused by the air resistance generated during the operation, thereby causing failure of the wind turbine generator.

Accordingly, there is a need for a method capable of efficiently transporting the offshore wind turbine to a location where the offshore wind turbine is to be installed, performing the assembly work and installation work of the offshore wind turbine generator simultaneously, and smoothly and efficiently installing the offshore wind turbine generator.
