O_2 concentration which is injected to ballast water with ozone gas was evaluated, and O_2 concentration of ballast tank shortly after ballasting was predicted by calculation and model experiment. Coating degradation test was carried out under normal O_2 concentration (20.9%) and high O_2 (30%) concentration humid condition respectively. Testing temperature was set to 343K as accelerating condition. Effect of O_2 concentration was evaluated after 65days testing. The obvious difference between normal and high O_2 condition was not found.

通过计算和模型试验，估算了压载水充入臭氧后的O_2浓度，并预测了压载水充入后压载舱内的O_2浓度。分别在正常O_2浓度（20.9%）和高O_2浓度（30%）潮湿条件下进行了涂层降解试验。试验温度设定为343K作为加速条件。65天后评价O_2浓度的影响。正常氧和高氧条件下的差异不明显。
