ABSTRACT:
An apparatus for the removal of oil from large bodies of water, such as oceans. A rotating drum, whose surface is composed of a steel mesh, retrieves oil off the surface of water. An adjustable vacuum is created within the rotating drum, causing contaminated water to pass through and oil to adhere to the steel mesh of the drum. The drum transports the oil to a collection point, where a high pressure water stream from within the drum works in conjunction with a squeegee on the drum surface to remove the oil layer from the mesh. Through the use of Archimedean screws, the oil is then transported up to the collection ship to which the apparatus is attached. Unique rake tines prevent solid debris, such as seaweed, from contacting the drum and subsequently clogging the system. The configuration of the apparatus provides for the connection of several recovery drums side by side, thus expediting the collection and removal of large oil spills.
