Zusammenfassung:The invention relates to a device for inspecting a damage or a crack of part of a hydro turbine, comprising at least one underwater remote operated vehicle (20) or autonomous underwater vehicle, at least one floatable or buoyant probe (26) or at least one probe (26) and means to make said at least one probe floatable, said probe comprising at least one imaging device (32) and/or laser scaler, and means for transmitting data from said probe to said vehicle or to a ground station when it is distant from said vehicle. L'invention concerne un dispositif d'inspection d'un endommagement ou d'une fissure d'une partie d'une turbine hydraulique, comprenant au moins un véhicule téléguidé sous-marin (20) ou un véhicule sous-marin autonome, au moins une sonde flottable ou flottante (26) ou au moins une sonde (26) et des moyens pour réaliser ladite au moins une sonde flottable, ladite sonde comprenant au moins un dispositif d'imagerie (32) et/ou un dispositif de mise à l'échelle laser, et des moyens pour transmettre des données de ladite sonde audit véhicule ou à une station au sol lorsqu'il est éloigné dudit véhicule.
