Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power, in particular to a tension leg wind turbine installation platform. Background Art

[0002] Currently, the floating wind power form is mainly based on semi-submersible foundations. Although the tension leg foundation has characteristics such as a small sea area requirement, low engineering cost, and being friendly to wind turbines, due to its motion characteristics such as excess buoyancy, there are great challenges in offshore installation, wind turbine integration, and replacement of large components.

Specifically, the floating wind power foundation platform is temporarily moored using a deep-water dock. After the wind turbine is integrated in place by an onshore crane or a wind turbine installation vessel, the integrated towing of the wind turbine foundation and the on-site connection process are carried out.

[0004] The traditional solution is not only restricted by deep-water dock resources, but also has comprehensive problems such as complex processes, resource limitations, engineering risks, and huge costs in the integrated towing and connection operations of the wind power foundation.

[0005] Although the problem of replacing large wind turbine components is the reverse process of on-site wind turbine integration, the challenges it brings, such as integrated backhaul and dock demolition, are even greater. Summary of the Utility Model
