The invention relates to a method and a system for balancing a floating platform provided with an active ballast system. The platform comprises at least three floats (Nb ≥ 3) and three or more actuators which are configured to adjust the mass of liquid inside the floats. The method involves measuring parameters such as roll angle (φ), pitch angle (θ) and optionally altitude (z), each corresponding to one degree of freedom. These parameters are filtered by a low-pass filter, and a filtered-error vector (E) is calculated. An intermediate-command vector (U) is calculated, with the intermediate commands being proportional to the filtered errors, and is used with a distribution function (Z) in order to determine an actuator vector (A). The actuators are controlled to adjust the liquid masses, thereby stabilising the platform. This method is applicable in marine environments where the stability of the platform is important, such as in offshore wind turbines or floating production systems.

Resumen de: US20260218678A1
To provide high stability at low cost, a ring-based floatation system for a floating vertical-axis wind turbine is proposed. The system uses a buoyancy torus with a finite shell thickness, which can be sealed to prevent water from leaking inside the torus. This torus shape has an outside and inside diameter on a horizontal plane while having a circular cross-section in a vertical plane. This buoyancy torus serves as a floatation tube to provide buoyancy at a large maximum radial extent to enhance platform stability in terms of both inertia and metacentric height. The torus shape (or a similar faceted shape made of several cylindrical tubes connected in a circle) also provides high radial asymmetry and high structural robustness. This buoyancy torus supports rotating wind turbine blades which are affixed to a rotation ring, where the torus and the rotation ring have the same axis of revolution and where the blades and the rotation ring rotate about this axis of revolution. One or more electrical generators can be placed between the rotation ring and the buoyancy torus (or a foundation for an onshore wind turbine) to convert the rotational power of the blades (communicated to the rotation ring) into electrical power. This ring-based buoyancy platform can be ballasted by a variety of methods and can also be used to support offshore oil and gas drilling platforms.
