  • Patent number: 11905671
    Abstract: A sorbent-based oil skimmer is configured to collect oil from an oil layer and passively deposit the oil in an encasing, where the oil can be continuously or periodically removed. The oil skimmer includes an encasing and a sponge that is partially enclosed within the encasing. The sponge has a top sheet in contact with the oil layer and a shell connected to the top sheet, where the shell extends into the encasing. Oil collected by the top sheet is conveyed through the shell, where it is deposited into the encasing under the force of gravity. In some applications, the sponge is manufactured from a silicone-based polymer that has been impregnated with carbonaceous material. The skimmer may optionally include counterweights, ballast tanks, buoyancy adjustment systems and propulsion modules.
