Sailing wind turbine ship able to pivot for efficient and resilient energy production and delivery

Resumen de: GB2700683A

A ship 1 with one or multiple wind turbines 2 installed on it. The ship has a multihull 3 construction with three or more hulls positioned rationally symmetric along the longitudinal axis of the ship, such that at least two hulls float on the water, with at least one hull being in the air, not on the water. This allows the wind turbine ship to pivot along the longitudinal axis in case the ship capsizes, such that at least two hull remain floating on the water at all times. This provides resilience in sea storms as the wind turbine ship remains its full structural and functional integrity and continues operations. The wind turbines may serve a dual purpose simultaneously: first, they generate electrical energy, and second, they function as sails for ship propulsion. This enables the wind turbine ship to sail to offshore destinations where the wind conditions are beneficial for energy production and to destinations where the produced and onboard stored energy is delivered to.
