The corrosion of internal structures of ships is a complex issue, influenced by many variables. Many guidances for example have been published to prevent members from corrosion and wear. These guidances, which are controllable within the acceptable criteria, can go a long way in reducing corrosion. For more rational and precise corrosion life assessment, many research plans for example have been made and resarches are under way. The target of this paper are to offer electrochemical properties in dry/wet alternation tests for unified understanding of various kinds of corrosion tests and to consider actual ship hull corrosion connection with dry/wet alternation test results. Acceleration rate of dry/wet test in comparison with actual hull corrosion, electrochemical properties of dry/wet test, effects of some paint specifications on corrosion progress and so on are clarified.
