ABSTRACT:
An apparatus for the removal or inhibition of underwater growth on an elongate submerged body. It includes at least one collar adapted to extend loosely around the elongate submerged body (28). The collar includes a breaker device to apply impact force on the underwater growth to break it up. The breaker device includes a voluminous body (16) into which ambient water flows in and out. The device can advantageously include rollers (12). The apparatus on a smaller scale can act to inhibit the settlement of new underwater growth.
