El objetivo de este estudio es el análisis del comportamiento hidrodi-námico de una Plataforma Eólica Flotante (FOWT) bajo oleaje regular. El análisis considera tres grados de libertad: Heave, Pitch y Surge. El estudio se ha realizado mediante una herramienta CFD (Computational Fluid Dynamics), basada en las ecuaciones de Navier-Stokes y el Método de los Volúmenes Finitos, y los resultados se han comparado con ensayos experimentales realizados en el Canal de Ensayos Hidrodinámicos de la Universidad Austral de Chile (CEH-UACh). Para este análisis se utilizó una plataforma semi-sumergible genérica a escala bajo diferentes condiciones de oleaje regular, obteniendo datos de altura de ola en diferentes puntos del volumen de control y movimientos de traslación y rotación para obtener los RAO's (Response Amplitude Operator) en cada uno de los grados de libertad considerados. Para las simulaciones CFD se utiliza el software comercial STAR CCM+, donde las características del flujo se definen a través del Volumen de Fluido (VOF) y sus respectivas condiciones de contorno. Finalmente, se com-paran los resultados de ambas metodologías, mostrando un adecuado grado de correlación entre ellas.
