<p>In the event of an unprecedented catastrophe such as a Nankai trough earthquake, there is a risk that various related equipment and facilities would severely degrade. Therefore, it is extremely important to build a soundness assessment system that enables the early restoration of functions of oil storage tank. In this study, repeated stress tests for vinyl ester resin-based glass flake coatings which are typically applied to bottom plates of tanks were conducted in order to estimate the degree of damage to the coating during an earthquake. In the case of testing the coating at average film thickness of 400 μm, physical damages such as cracking or delamination occurred as the strain on the coating surface reached about 1.38%. Furthermore, it is found that physical damage was also caused by repeated strain below this limit, and the tendency showed an S-N curve similar to that seen in metal fatigue fracture. In addition, field survey on corrosivity of sedimented waters on inner bottom plate of actual oil-storage tanks and long-term immersion tests for damaged coating samples were conducted. As results, the corrosivity is almost same that in marine environments and severe corrosion of steel under physical damage of coating were not detected. Based on these results, a flowchart for determining the next overhaul inspection time considering the aging of the performances of anti-corrosive coatings was proposed. The analysis following this chart enable us to estimate the soundness of the coating immediately after an earthquake without removing oil for overhaul inspection and can provide a rational criterion for emergency response.</p>
