The invention relates to a device for taking up oil from a water surface, comprising a container for receiving the oil and an oil-transporting means, wherein a portion of the oil-transporting means can be brought into fluid communication with the water surface and another portion of the oil-transporting means is disposed within the container, wherein the oil can be transported into the container via the oil-transporting means, wherein the oil-transporting means is formed from a hydrophobic fabric, the surface of which comprises filament-shaped and/or grid-like structures which are designed in such a way that they retain a gas layer on the surface of the hydrophobic fabric under water. The invention further relates to a corresponding method for taking up oil from a water surface.
