Using Oil Skimmers on a Large Spill
Skimmers are devices that are used to recover spilled oil from the water's surface. They can be self-propelled, used from the shore, or operated from vessels. There are three types of skimmers and their effectiveness depends a great deal upon conditions at sea. If the water is moderately rough or choppy, the skimmers usually recover more water than oil.

There are skimmers which use "selective adhesion" as their method of removal and take in more oil than water. They are discs or drum types.--For smaller spills belt or floating tubes can be used.
