Description

Installation method using vessel for installing sea wind power generator

The present invention, after safely assembling and loading the components of the offshore wind power generators prepared on landers wharf or offshore transport barge in the offshore wind power generator installation dedicated ship, the dedicated ship can be moved to the installation area to install the offshore wind power generator quickly and safely The present invention relates to a method of installing an offshore wind power generator using a dedicated line for installing an offshore wind power generator.

More specifically, the components of the sea wind power generators such as towers, nacelles, hubs, blades, etc., prepared either on land paddles or offshore barges. After docking a floating crane at a place loaded on any of the onshore docks or offshore transport barges, it is lifted and assembled in order to the offshore wind turbine installation dedicated line, and the offshore wind turbine loaded on the offshore ship is brought to sea. After transporting, the dedicated ship is jacked down by spud down to stabilize the installation area, and the offshore wind power generators on the dedicated ship are installed and the lower part such as a monopile or jacket provided in the area. Offshore wind power generator installation method that can be installed quickly and safely on the substructure All.

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.

Such a wind turbine is installed on the sea off the coast by a barge and is located at a certain distance from the coast. As a related art related to offshore wind power generation system, Korean Patent Application Publication No. 10-2012-0001384 (2012.01.04 , "Method for constructing a marine mono-file for a wind turbine generator", and "Drag-reducing device for offshore wind power generation system" of Korean Patent Application Publication No. 10-2012-0099891 (2012.12.12) "Transportation barge, installation structure of marine structure and method of installing marine structure " in No. 10-2012-0138819 (2012.12.26) have been presented.

In the above-mentioned prior art, the "transport barge, the offshore structure installation system and the offshore structure installation method" is a transport barge for use in the sea installation of a structure, characterized in that the loading barge on which the structure is mounted in the barge is movable up and down do.

1, the conventional marine structure installation system is provided with a transportation barge line 1 and a crane operation line 5. The transportation barge line 1 includes a hull 2, a dropper 3 and an actuator group The crane working line 5 is composed of a hull 6, a jack up device 7, a deck crane 8 and a crane operator room 8a. The deck crane 8 and the crane operator chamber 8a of the crane working line 5 are provided on the hull 6 and the jack-up device 7 is provided with a jack-up leg 7a. Is provided with a hook 8b for suspending the transported object.

In the conventional marine structure installation system, the loading unit 3, which vertically moves up and down by the actuator group 4, is mounted inside the transportation barge 1, so that the loading barge 1 is dropped from the transportation barge 1, There is an advantage that the transportation barge line 1 and the dropping bag 9 are prevented from colliding with each other when hung up the bag 9.

However, in order to shorten the installation time of the offshore structure, the conventional barbed structure installation system operates the barge 1 to float on the sea without fixing the barge 1 above the sea level.

When the conveyance barge 1 is operated in a floating state in the vicinity of the crane working line 5 and operated so as to generate a high wave height due to deterioration of the marine environment, ) Are vertically and horizontally oscillated.

When the transport barge 1 is severely rocked in this way, the deck cranes 8 of the crane operation line 5 can quickly and safely lift the cargo 9 loaded on the loading base 3 of the transport barge 1 And there is a problem that the lifting and installation work of the dropper 9 is delayed or interrupted.

In addition, the conventional marine structure installation system has a high possibility of occurrence of safety accidents in the case of frequent weather deterioration in the sea, and further cost loss due to frequent delay and interruption of lifting and installation work 9 occurs, There is a problem in that a separate cost is required for mounting the actuator group 4 and the dropper 3 in the interior of the body 1.

In addition, when the offshore structure installation system is constructed, the transport barge 1 and the crane work boat 5 are operated simultaneously, and the overall construction period of the offshore wind power generation system is delayed. There was a problem such as increased.
