The catholic protection have been applied to steel structures located in submerged zone of sea wave environments. The purpose of this study is to examine the protective effectiveness of catholic protection and steel potential behavior of steel affected by sand erosion at sea bottom. The study described in this paper was carried out by using existing steel pipe pile structure and test pieces. From the test results, it was found that protective effectiveness of cathodic protection was recoginized even for the steel under sand erosion. Also, it was found that the behavior of steel potential was affected by the sand drift at sea bottom caused by (significant) wave.
