SAILING WIND TURBINE VESSEL CAPABLE OF PIVOTING FOR EFFICIENT AND RESILIENT ENERGY PRODUCTION AND ENERGY TRANSPORT

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.
