Description

Technical Field

[0001] The present invention relates to the technical field of floating platforms, in particular to an ultralight floating platform. Background Art

[0002] Floating wind turbine platforms are deployed offshore, where environmental conditions are more severe than nearshore. Due to high wind and current speeds, the platforms experience significant flow loads and swaying motion, which reduces turbine efficiency. Furthermore, these high flow loads can cause vortex-induced vibrations (VIVs), which can increase structural fatigue and pose safety risks. Furthermore, the cost of floating wind turbine platforms is currently high, leading to the search for a floating platform design that can reduce both flow loads and costs.

[0003] Patent application CN202180046640.4 discloses a reinforced concrete floating wind turbine platform for mass production. The geometric design provides hydrostatic natural prestressing in the concrete, enabling it to operate under compression. This improves the structural response of the platform when operating in its most efficient mode, prevents cracks or fissures in the concrete, reduces permeability, and enables the reduction of steel reinforcement in the structure, while also improving operational safety. Furthermore, the present invention provides a system for anchoring anchor cables to a reinforced concrete truss structure. This system evenly distributes anchoring stress, minimizes prestress in the upper area of the platform, and increases the area for distributing shear forces due to cross-sectional variations between the platform and the wind turbine tower. Furthermore, the geometric design provides the versatility of adopting low-draft SPAR, semi-submersible, barge, or buoy solutions. The wind turbine can be mounted centrally or eccentrically on the structure to accommodate different draft requirements, environmental, and transportation conditions. However, this structure does not reduce operating costs during use, so a new structure is proposed to address this technical problem. Summary of the Invention
