Marine facilities including vessels and power industries should be obligatorily cooled to navigate the vessels and operate facilities in order to avoid the overheating of their systems. Thus, most facilities use seawater as a coolant in their systems in order to achieve cooling that is continuous and essential. However, there are problems such as corrosion and biofouling that are caused by marine organisms due to the utilization of seawater. To resolve these problems, we have investigated a novel method to control corrosion and the HClO (hypochlorous acid) concentration at the same time in seawater pipes by using cathodic protection and the electrochlorination method. As a result of this experiment, we were able to figure out the cathodic protection current density, the effect of the corrosion protection, and the HClO concentration as a function of various conditions.
