To help ensure that the skimmed oil does not contain excessive water, many API separators also include an oil roll skimmer. This For this reason, an oil skimmer pipe is almost always used as a backup oil removal de- vice. Oil

The main advantage of this type of skimmer is that, the oil that is collected can be recycled. Suction skimmers do not do very well in rough or choppy water because the wave action will force more water than oil into the skimmer.
