Floating fan foundation and fan

Abstract

The invention discloses a floating fan foundation. The foundation comprises a support structure, a floating structure and a mooring system, wherein the support structure is located in the center of the floating fan foundation and is connected with a fan body to support the fan body; the floating structure is located around the support structure and is connected with the support structure to provide buoyancy for the fan foundation; the mooring system is connected with the floating structure to locate the floating fan foundation; the floating structure comprises at least three floating body structures and at least three connecting structures, and the connecting structures are fixedly connected with two adjacent floating body structures respectively. The floating structure adopts a form of adouble-layer outer plate, the strength of the outer plate is increased, the thickness of the outer plate is reduced, the amount of steel used is saved, the floating structure is connected with a middle cylinder through a connecting bridge, and is convenient for workers to operate and maintain, and the whole floating fan foundation is few in amount of steel used, high in safety, and suitable for transitional deep water areas.

Description

technical field [0001] The invention relates to the technical field of offshore wind power foundations, in particular to a floating fan foundation and a fan. Background technique [0002] With the deepening of human understanding of offshore wind resources and the advancement of wind energy development technology, the development of wind resources has developed from near and shallow seas to deep and distant seas. Floating wind turbine foundation is one of the key equipment for deep sea wind energy development. On the basis of oil and gas development technology, various forms of floating foundations have appeared in recent years, among which semi-submersible floating foundations can be installed and debugged on the shore, and then towed to the installation area, which has high flexibility and wide application range , Low installation cost and other advantages, so it has developed rapidly. [0003] Many international companies and research institutions have proposed the conc...

AI Technical Summary

Problems solved by technology

Existing semi-submersible floating fan foundations often use large-diameter, large-wall-thick cylinder structures to provide buoyancy, which increases the construction technical threshold and the amount of steel used, and increases production costs. Moreover, small-diameter buoys are used between large-diameter The cross brace structure connection is prone to fatigue damage, and the safety is difficult to guarantee

In addition, the existing floating foundation basically adopts a catenary mooring system with a catenary full anchor chain, which is expensive and not suitable for transitional water depth areas.
