Evaluation of Ballast Tank Corrosion in Hypoxic Seawater
Investigations were undertaken to evaluate the impact of hypoxia on corrosion within ballast tanks. Carbon steel coupons were exposed to seawater in alternating fill/drain conditions encountered in operational ballast tanks. The following alternating exposure conditions between fill/drain conditions were examined: 1) oxygenated seawater/air, 2) hypoxic seawater (0.2 mg/L O2)/hypoxic gas. The effect of oxygen on corrosion in a hypoxic environment was evaluated by introducing oxygenated air into the hypoxic chamber at the midpoint of the experiment. Differences in corrosion rate and morphology before and after the introduction of oxygen were quantified.
