Problems solved by technology

In this case, the structural material is concrete, which results in a large displacement and greater platform weight
The five-post configuration offers advantages in terms of stability, but the structure has a larger floating area, which makes it more sensitive to currents, adding to the complexity and cost of the mooring system
This makes the system more complex and requires redundancy to ensure its operation in case of failure or emergency

Embodiment Construction

[0049] In this document, the term "comprise" and its derivatives (such as the present participle of "comprise", etc.) should not be interpreted in an exclusive sense, that is, these terms should not be interpreted as excluding that what is described and defined may include Possibilities for other elements, steps, etc.

[0050] In the context of the present invention, the term "about" and its cognates (eg "approximately", etc.) are to be understood as meaning very close to the value accompanying the above term. That is, deviations from the exact values ​​should be accepted within reasonable limits, as those skilled in the art will understand that such deviations from the expressed values, due to measurement inaccuracies and the like, are unavoidable. The same applies to the terms "about", "approximately" and "substantially".

[0051] The following description is not limiting, but is given for the purpose of describing the broad principles of the invention only. Embodiments of...

Abstract

A semisubmersible floating platform (1) for supporting at least one wind turbine, comprising four buoyant columns (3), each of them being attached to a ring pontoon (2); a transition piece (4) configured to support one wind turbine, disposed on the buoyant columns (3); and a heave plate (5) assembled to the internal perimeter of the ring pontoon (2). The ring pontoon (2) comprises four pontoon portions forming a quadrilateral-shaped ring pontoon (2) wherein the first end of each column (3) is attached to a respective corner of said quadrilateral-shaped ring pontoon (2). The heave plate (5) islocated in the internal perimeter of the ring pontoon (2), both defining a hollow. The pontoon (2) is preferably divided into a plurality of compartments or construction blocks that may be filled withfixed ballast, such as concrete. The transition piece (4) has four arms arranged in star configuration and protruding from a central point at which the wind turbine is located, the connection betweenthe transition piece (4) and the columns (3) being designed to be located above the sea splash zone. Each of the buoyant columns (3) comprises at least one ballast tank configured for allocating seawater in order to adjust the draft and to compensate for the inclination of the platform (1), said at least one ballast tank comprised in each column (3) being independent of the at least one ballasttank of the other columns (3).

Description

technical field [0001] The present invention relates to floating offshore structures. More specifically, the present invention relates to semi-submersible floating offshore structures for supporting wind turbines. Background technique [0002] Various offshore structures exist. They usually have a top structure that accommodates different equipment depending on their application. Examples of such equipment are plumbing equipment, drilling equipment, storage and energy generation equipment. The design of the entire structure is usually dictated by its intended application. [0003] An example of a semi-submersible offshore platform for oil and gas extraction is disclosed in US8418640B2. Other examples of offshore structures of this type are disclosed in US2007224000A1 , US7963241B2 , US8807874B2 and US2014 / 305359A1 . As an example, US2014 / 305359A1 discloses a method and system for reducing vertical motion on a semi-submersible floating platform for exploration and produc...
