An apparatus powered by waves, currents, or tides for eliminating or preventing marine growth on a structure. The apparatus includes (a) at least one ring adapted to surround a submerged support member of the structure, the at least one ring being substantially continuous; (b) at least one pair of rollers rotatable against a surface of the support member for cleaning the surface of the support member; and (c) a linking member for linking the roller means to the ring without interrupting continuity of the substantially continuous ring and for allowing rotation of the rollers against the surface of the support member in response to forces generated by the waves, currents or tides.
