A UNIVERSAL-JOINT-TYPE CONNECTION DEVICE FOR CONNECTING AN OFFSHORE WIND TURBINE PLATFORM TO THE SEABED

Resumen de: EP4800240A1

The present invention belongs to the technical field of offshore power generation, and specifically discloses a universal-joint-type connection device for connecting an offshore wind turbine platform to the seabed.

ELECTRICITE DE FRANCE

Resumen de: WO2026162435A1

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.
