Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0027] In a specific embodiment of the present invention, a method for fast floating installation of an offshore wind turbine as a whole consists of Figure 1 ~ Figure 4 shown, including the following steps:

[0028] a. The fan is pre-installed on the ship, and the ship is moved so that the fan 1 is located in the notch of the supporting device 2 on the side of the ship, and the holding mechanism 4 fixes the fan 1 on the supporting device 2;

[0029] b. When the fan is installed on the ship, the jacking device moves, driving the holding mechanism 4 and the fan 1 to move upward along the axial direction of the supporting device 2, and the fan 1 leaves the dock. At the same time, th...

Abstract

The invention provides an overall rapid floating loading method for an offshore wind turbine. Overall shipping, transportation and offshore rapid floating loading of the multiple wind turbines can be carried out in one voyage. A U-shaped draught fan supporting device is arranged on the ship side and extends out of the ship edge, a draught fan holding mechanism is arranged on the device, and the draught fan holding mechanism can move up and down along a vertical sliding way on the draught fan supporting device while holding a draught fan. A telescopic bearing platform is arranged at the bottom of the supporting device and used for bearing the weight of the whole draught fan in the transportation process. During offshore installation, the fan holding mechanism raises the height of the fan, the telescopic bearing platform retracts, the ship is moved to enable the fan to be located over a fan base, the fan is lowered to the fan base, the fan holding mechanism is loosened after the fan is fixed, and a connecting rigging is dismantled. The ship is moved to the next position, the actions are repeated, and installation of all the whole fans in one voyage is completed.

Description

technical field [0001] The invention relates to the field of installation of offshore wind turbines, in particular to a method for fast floating installation of an offshore wind turbine as a whole. Background technique [0002] At present, there are mainly two types of offshore wind turbine installation in China: separate installation and integral installation, both of which rely on floating cranes. Split installation requires a floating crane with outriggers, the efficiency of split assembly is low, and high-altitude operations are more affected by wind. The overall installation has more restrictions on floating crane resources, and the 5MW wind turbine has almost reached the overall installation limit. With the continuous advancement of technology, 8MW, 10MW and even 14MW wind turbines continue to emerge. In order to realize the rapid installation of fans, it is imperative to develop a modular, standardized and efficient overall fan installation. Contents of the inventi...
