Segelndes Windturbinenschiff fähig zu Pivotieren für effiziente und resiliente Energieproduktion und Energietransport

Resumen de: DE102024000107A1

TECHNISCHES GEBIET UND ANWENDUNGSBEREICHDie Erfindung bezieht sich auf die Weiterentwicklung der Energieproduktion aus Offshore-Windkraft und deren Energietransport mittels eines neuartigen segelnden Windturbinenschiffes.ZUSAMMENFASSUNGDie Erfindung beschreibt ein Windturbinenschiff (1), dass autonom auf hoher See mittels Windturbinen (2) segelt und Energie produziert, diese speichert und transportiert. Das Windturbinenschiff (1) ist ein Mehrrumpfschiff mit drei oder mehr Rümpfen (3), zwischen denen mindestens eine Windturbine (2) installiert ist. Die Rümpfe (3) sind rotationssymmetrisch parallel zur Längsachse des Windturbinenschiffes (1) installiert. Dies ermöglicht es dem Windturbinenschiff (1) zu pivotieren, d.h. um die eigene Längsachse zu rotieren, um resilient bei Seestürmen zu sein. Im Fall, dass es bei starkem Wind oder Wellengang kentert, behält es seine vollständige strukturelle und funktionale Integrität durch seine rotationssymmetrische Konstruktion. Die Windturbinen (2) werden auf zwei Arten gleichzeitig genutzt. Erstens für die Produktion von elektrischer Energie, die an Bord in den Rümpfen (3) gespeichert wird, z. B. in Batterien oder mit Power-to-Hydrogen. Zweitens werden die Windturbinen (2) mittels Gierbewegungen als Segel für den Antrieb und die Steuerung des Windturbinenschiffes (1) verwendet. Damit kann es autonom auf hoher See in Gebieten segeln, an denen die Windbedingungen für die Energieproduktion günstig sind, d.h. stärkere und gleich
