Description

Technical Field [0001] The present invention relates to a method of constructing a marine wind turbine using a dedicated barge,

The present invention relates to a marine construction method of a wind turbine using a dedicated barge, and more particularly, to a method of constructing a marine structure of a wind turbine using a dedicated barge, The present invention relates to a method for constructing an offshore wind turbine using a dedicated barge.

In addition to hard energies that cause pollution of the earth by discharging various pollutants such as coal, petroleum or nuclear energy, natural soft energies such as solar, geothermal, wave, tidal and wind power, There is growing interest in electric production using green energy.

In such electricity generation using green energy, the wind power generation has been attracting attention as an efficient power generation means since the power generation cost can be lowered due to the enlargement of the wind power generator and the development of the technology.

In this type of wind power generation, a large installation site is secured as compared with that of onshore wind power generation, and noise and visual environmental problems are solved by being installed within 15 km of the coast, and the offshore wind power Development is more preferred.

Here, the wind turbine generator includes a tower, a blade, a hub, a nacelle, a gear box, a control device for controlling a generator and various safety devices, a hydraulic brake device and a power control device The blade converts the kinetic energy of the wind into a mechanical rotational force and amplifies the rotational force input from the power transmitting device of the nacelle. The generator converts the mechanical rotational force into electric energy, inverter converts DC electricity to AC electricity to supply electric power.

In recent years, large wind power generation facilities are being constructed with offshore wind power because on-land wind power is limited in the surrounding aesthetic or location, and the wind speed is relatively weaker than on the sea.
