ABSTRACT:
A method of minimizing adherence of living marine organisms on exposed surfaces of a component submerged in a fluid medium containing such organisms is provided. The method simultaneously minimizes danger to higher forms of animal life present in the fluid medium. The method includes determining the component to be protected and its size and shape. In addition, the material such component is manufactured from is determined. At least one electrode is positioned adjacent an exposed surface of the component to be protected. A system to create a current flow path is provided by positioning a second electrode spaced from the other electrode also adjacent the exposed surface of the component when it is determined that the material the component is manufactured from is non conductive. On the other hand, when the component is manufactured from a material capable of conducting a current therethrough it may be used as one of the electrodes. A voltage is applied to the system to create a current flow path. In this manner, an electrical field is generated which has an intensity at least sufficient to cause the organisms to close.
