The document describes a number of different oil collection devices presently available, giving the manufacturer's name and other pertinent information on each method. In addition, some information covered by various patents on the subject of skimmers is also included. The skimming devices described in the report consist primarily of three different types: weir, drum and belt. The skimmers are classified as belonging to one of the major categories. The weir type uses the principle of overflowing a weir to separate the oil from the surrounding water, whereas the belt and drum types utilize the principle of selective adsorption of the oil from the water. In each category, skimmers have been listed in alphabetical order. No attempt has been made to determine the relative effectiveness of any of the skimming methods or to compare their merits. The equipment is described in as much detail as practicable from the information available. Additional data can be secured from the reference indicated, or by contacting the manufacturer or inventor directly.
