Gravity-Based Foundation System for the Installation of Offshore Wind Turbines and Method for the Installation of an Offshore Wind Turbine Foundation System

摘要

The present invention relates to a gravity-based foundation system for offshore wind turbine installation which enables the transport, anchoring and subsequent refloating of the structure-wind turbine assembly once anchored, giving great versatility to the solution with regard to the uncertainties associated with the installation and terrain response in the short and long term, as well as the method for installing the preceding gravity-based foundation system.

主权项

1. Gravity-based foundation system for offshore wind turbine installation that comprises:
three floating reinforced concrete foundations built with self-floating concrete caissons, equipped with valves for filling them with water and emptying the water out enabling their ballasting and anchoring at their final location, a metal structure which connects the floating concrete bases by means of a connecting element to the wind turbine tower, and a metal element which connects the floating concrete bases to the wind turbine, metal element on which a docking area is installed, a maintenance platform and access stairs.
