FLOATING SYSTEMS FOR WIND TURBINES USING SEMI-SUBMERSIBLES

Resumen de: WO2023244607A1

Delivery of a high volume of floating systems for wind turbines can involve the standard design of sections, such as "tubes" or "cans," comprising a rolled plate and ring stiffeners. The delivery can then involve the transportation of the sections in blocks to an assembly site that is closer to the planned installation point. The sections are used to manufacture semi-submersibles at the assembly site using a barge with cranes. The delivery can then involve the transportation of each of the semi-submersibles to a platform, such as a standard jack-up vessel or a crane jacket, near which the semi-submersible is temporarily attached to allow the installation of the Tower, the nacelle, and blades. Finally, the delivery involves the transportation of the completed wind turbine to the planned installation point, where it can be attached to a pile driven into the seafloor or moored during use.
