Oil Spill Skimmers:
Skimming is a process of
removing oil from the top of the water surface. This is achieved by the use of
various mechanical devices such as pumps, vacuum systems etc. The efficiency of
a skimmer depends upon the sea and weather conditions. As the water conditions
become rougher the skimmer starts to pull in more water along with oil.
Major types of skimmers

Once
oil is contained by the booms, it has to be removed from the water.
Skimmers are used to remove oil from water
without changing the chemical or physical properties of the oil. How well a
skimmer works depends on the type of oil spilled, the thickness of the slick
and, again, the weather.
