Resumen de: WO2025146447A2
The invention describes a wind turbine vessel (1) which autonomously sails at high sea by means of wind turbines (2) and produces, stores and transports energy. The wind turbine vessel (1) is a multi-hull vessel having three or more hulls (3), between which at least one wind turbine (2) is installed. The hulls (3) are installed rotationally symmetrically parallel to the longitudinal axis of the wind turbine vessel (1). This makes it possible for the wind turbine vessel (1) to pivot, that is to say to rotate about its own longitudinal axis, in order to be resilient in the case of sea storms. In the event that it capsizes in strong winds or waves, it retains its complete structural and functional integrity as a result of its rotationally symmetrical design. The wind turbines (2) are used simultaneously in two ways. Firstly, they are used for the production of electrical energy which is stored on board in the hulls (3), for example in batteries or with power-to-hydrogen. Secondly, the wind turbines (2) are used as sails for driving and controlling the wind turbine vessel (1) by means of yawing movements. It can thus sail autonomously at high sea in areas in which the wind conditions are favourable for energy production, that is to say it can use stronger and more uniform winds, and transport the energy stored on board to a location where it can be fed into the energy grid.

The tops of the tubular structures, opposite the pylon, are separated by an angle ranging from 25° to 80°.Additionally, there is a connection tube and a counterweight affixed to the tubular structures at the level of the pylon and at the level of their tops opposite to the pylon. The length of the tendon fixed to the pylon exceeds that of the other two tendons.

0000 A floating power generation system incorporates a scotch yoke mechanism that is coupled with an electrical generator to produce power and is actuated by a fin assembly having a plurality of fins that move or pivot from a first pivot position to a second pivot position. The fins are coupled with the yoke of the scotch yoke by a cable to move the yoke back and forth in a reciprocating motion. As the fins move back and forth from one side of the water flow direction to the other, the yoke reciprocates and turns the flywheel to produce electrical power. The floating power generation system may employ two fin assemblies, wherein a first fin assembly directs water through the plurality of first fins into the plurality of second fins of the second fin assembly to force the second fins in an opposing pivot orientation from said first fins.
