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 present invention addresses the problem of providing a tension-mooring cable for a tension-moored floating body, with which it is possible to, without adjusting the lengths of the tension-mooring cables in each mooring cable bundle that moors and supports the tension-moored floating body, equalize tension generated in the tension-mooring cables and prevent occurrence of resonance with the frequency of waves on the ocean.

Vertical-axis wind turbines (VAWTs) have inherent advantages over horizontal-axis wind turbines (HAWTs) resulting from the low center of gravity primarily caused by the low height of the drivetrain relative to the rotor. The low center of gravity is one of the main drivers for development of VAWTs for floating offshore wind energy generation, where the reduced center of gravity has positive system benefits by reducing the demands placed on the floating platform and its associated mass and cost. This advantage for VAWTs can be further enhanced by lowering the elevation of the drivetrain by housing it within the platform column.

Abstract An energy-harvesting compute grid includes computing assemblies that cooperate with mobile energy harvesters configured to be deployed on a body of water. The plurality of energy harvesters are positioned on and move adjacent to an upper surface of a body of water, and the locations of the energy harvesters can be monitored and controlled. The widespread gathering by the harvesters of environmental data within that geospatial area permits the forecasting of environmental factors, the discovery of advantageous energy-harvesting opportunities, the observation and tracking of hazardous objects and conditions, the efficient distribution of data and/or tasks to and between the harvesters included in the compute grid, the efficient execution of logistical operations to support, upgrade, maintain, and repair the cluster, and the opportunity to execute data-gathering across an area much larger than that afforded by an individual harvester (e.g., radio astronomy, 3 D tracking of and recording of the communication patterns of marine mammals, etc.). The computational tasks can be shared and distributed among a compute grid implemented in part by a collection of individual floating self-propelled energy harvesters thereby providing many benefits related to cost and efficiency that are unavailable to relatively isolated energy harvesters, and likewise unavailable to terrestrial compute grids of the prior art.
