scamping
n.— «The regulation, aimed at protecting U.S. waters from the unintentional introduction of non-native species, requires ship owners to remove all “fouling organisms”— such as grass, moss and mussels—from the hull, piping and tanks “on a regular basis.” MARAD began complying last year by cleaning hulls with a brush in a process known as scamping.» —“Ghost fleet program grounded” by David Lerman Daily Press (Hampton Roads, Virginia) Mar. 13, 2007.
