Abstract

To inhibit marine growth on a submerged framework, one or more collars are placed loosely around each member of the framework, the collars having outwardly projecting vanes so that ambient water movement causes movement around or along the member. The vanes (5; 25; 45; 55; 65) are preferably hinged to the collar for limited pivotation and may be twisted or provided with extension portions to ensure axial movement.
