PCT No. PCT/GB86/00725 Sec. 371 Date Jul. 15, 1987 Sec. 102(e) Date Jul. 15, 1987 PCT Filed Nov. 28, 1986 PCT Pub. No. WO87/03261 PCT Pub. Date Jun. 4, 1987.A method is disclosed to provide a substantial reduction of marine corrosion in sea water by micro and macro biofouling. An alternating current is generated of a strength and frequency sufficient to shock marine biofouling organisms and sufficient to upset the normal behavior patterns of the marine biofouling organisms entrained in the sea water passing around or through the structure. A second combination of alternating and direct currents are generated between two strategically located electrodes whereby to release into the water around or within the structure controlled amounts of chlorine ions and copper ions to produce an environment actively hostile to potential marine biofouling organisms. The effect of releasing copper ions and chlorine ions simultaneously is that they co-operate in a synergistic manner that greatly enhances the biocidal effect on marine organisms over and above the effect of the separate use of copper ions and chlorine ions.
