Abstract: An absorbent oil collector is used as an oil spill combating apparatus and based on the use of an oil-absorbent material, e.g. a specially prepared wood fiber mass. In order to provide an oil collector of the kind concerned, which is flexible in that sense that its shape/size easily may be adapted to the actual oil spill situation and which may easily be picked up and collected when the absorbent material has been saturated with oil, the oil-absorbent material is encased within cylindrical stockings (1) of liquid-permeable material and which, along at least one longitudinal edge, is provided with catches, hooks or similar couplers (4) for the joining of a plurality of stockings (1), modules, forming a mat (5), which through rolling may be transformed into a section of a boom.
