Protecting oil tanks against earthquake disasters and age-related deterioration

In our earthquake-prone country of Japan, oil tanks have been damaged by earthquakes on numerous occasions.
Furthermore, coastal areas where great numbers of oil tanks are located have harsh environments that are conducive to the corrosion of steel tanks. In recent years, there has been an upward trend in accidents involving oil leaks caused by tank corrosion.
In an effort to enhance the safety of oil tanks, we are conducting research on estimating the damage to the main body of oil tanks and their floating roofs immediately after an earthquake to be able to respond to emergency situations. We are also conducting research on the diagnosis of age-related deterioration of oil tanks.
