The Prevention of infestation by mussels and marine organisms is required to decrease of ship fouling and condenser tube corrosion.The paper is devoted to the research and development of antifouling device of sea water which is one of electrolysis at the laboratory and an actual ship.The obtained results are as follows.1) Current concentration 0.3 A/m^3/hr, which is defined by the current of electrolysis at unit flow rate of sea water, is required to prevent grow of marine organisms.2) But when the sun shine is shut out, required current concentration is decreased to 0.1 A/m^3/hr.3) The treated sea water is not corrosive for metallic materials such as mild steel and copper alloys.4) The establishment of this method is proved by the satisfactory results of "Murasaki Maru" at 12 Months.
