Laboratory weight-loss measurements, electrochemical tests and SEM techniques were used to study the corrosive behaviour of electrolysed ballast water on marine carbon steel. Experimental results showed that for the mass concentration of Total Residual Chlorine (TRC) being 7.5mg/l, 17mg/l and 28mg/l respectively, the corrosion rates within seven days were 1.25, 1.46 and 1.7 times those in natural seawater. The corrosion rates decreased as time progressed. The corrosion rate in the electrolysed seawater is controlled by the cathodic process which is mass transfer controlled. The SEM observation showed that the topographies of carbon steel corroded in electrolysed ballast water with mass concentration of TRC 7.5mg/l and 17mg/l were characterised by denudation and rupture. Both the weight-loss and electrochemical tests revealed that the chlorinated seawater accelerated the corrosion rate and that this is consistent with result of the SEM observation
