Embodiment Construction

[0031] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0032] This embodiment discloses a floating construction method for offshore wind power floating foundations, which is carried out according to the following steps:

[0033] (1) if Figure 1 to Figure 4 It shows that the floating foundation of offshore wind power is composed of a floating platform and a mooring system, and the floating platform and the mooring system are prefabricated on land first.

[0034] The floating platform includes a column 1, an inclined strut 2, and a pontoon 3. The upper end of the column 1 is connected to the fan tower through a flange, and the lower end of the column 1 is fixedly connected to the pontoon 3. A plurality of inclined struts 2. Considering that the cabin and blades of offshore wind turbines are heav...

Abstract

The invention belongs to the technical field of offshore wind power foundations, and discloses an offshore wind power floating foundation floating transportation construction method. The method comprises the steps of firstly, pre-manufacturing a floating platform and a mooring system on land, and performing temporary fixation through an inclined mooring line and a straight mooring line; then, performing floating transportation towing on the whole of mooring system-floating platform-tower tube-fan; then, applying ballast so that an anchor foundation can sink and is embedded into the seabed to be fixed; enabling the floating platform with the upper fan tower tube to sink to the design draught position, and anchoring the inclined mooring line and the linear mooring line; draining water in some compartments inside a floating box; finally, adjusting the weight center position of the offshore wind power floating foundation. During towing, enough floating stability can be provided, the influence of wave loads is small during the in-situ state, overwater layering stretching system is obtained, and the difficulty for installing the mooring lines underwater is lowered; the anchoring foundation provides anti-pulling force by means of the ballast weight and friction resistance and is injected into the sea bed through piled loads and the internal and external pressure difference, and construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power foundations, and in particular relates to a floating construction method for offshore wind power floating foundations, which has good stability, convenient construction and installation, and low engineering and installation costs. Background technique [0002] The concept of floating foundation comes from the deep-sea oil and gas development platform, which means that the foundation is not in direct contact with the seabed, but is connected to the seabed through anchor cables or cables, so that the wind turbine can move freely in a relatively fixed area. The foundation is currently mainly in the research and development and demonstration stage, but it has strong adaptability to the marine environment. Compared with the implanted foundation, the construction is less difficult and the operation and maintenance costs are lower. Therefore, it has a good application prospect in the developme...
