Problems solved by technology

However, columns with circular or rectangular cross-sections are subject to greater wave force and water flow force. In addition, the eccentric design scheme uses less material for the platform foundation than the central layout scheme, but the platform is under different azimuths. There is a big difference between motion response and stability. The lateral stability of the platform is often smaller than the longitudinal stability. When the incoming wave direction is 90°, the stability of the platform is poor

Embodiment Construction

[0019] based on the following Figure 1 ~ Figure 3 , specifically explain the preferred embodiment of the present invention.

[0020] Such as figure 1 As shown, the semi-submersible floating eccentric fan system based on single point mooring includes a fan and a semi-submersible floating platform. The wind turbine includes blade 1, nacelle 2, hub 3 and tower 4. The nacelle 2 is connected to the blade 1 through the hub 3, the lower part of the fan is connected to the tower 4, and the bottom of the tower 4 is connected to the semi-submersible floating platform through a flange. The floating platform includes a working bridge 6, columns 7, heave plates 8 and buoys 9, wherein the upper parts of the three columns 7 are connected by the working bridge 6, and the lower parts of the columns 7 are fixedly connected to the circular heave plates 8 for lowering the semi-submersible floating platform. In the motion acceleration of the heaving direction, the fan is fixed at the junction o...

Abstract

A semi-submersible platform and eccentric fan system based on single-point mooring belongs to the field of renewable energy utilization, and is characterized in that a transverse bridge heaving plate and a longitudinal bridge heaving plate are connected through buoys connected to the heaving plates, and buoy cavities are formed in the positions where the buoys are connected; the turret mooring device is installed in the buoy cavity, so that the buoy can rotate relative to the turret mooring device moored on the seabed, the effect is that the platform always operates at the azimuth angle with the minimum environmental load, the stability of the platform can be guaranteed, and the load is reduced.

Description

technical field [0001] The invention belongs to the field of renewable energy utilization, relates to a floating fan system, in particular to a novel semi-submersible floating platform and mooring system based on single-point mooring. Background technique [0002] Nowadays, there is a sharp shortage of fossil energy, and problems such as environmental pollution and climate change are becoming more and more serious. In order to solve the above problems, governments of various countries are actively promoting the development of renewable energy technologies. As one of the most commercially promising renewable energy sources, vigorously developing wind power resources has become an important way to solve the problems of energy shortage and environmental pollution in our country. Compared with onshore wind energy, offshore wind energy resources are more abundant and stable, saving land resources is the main direction of China's wind power development in the future. [0003] In...
