ABSTRACT
This chapter discusses rational determination techniques of automaton parameters for thin film regions and point coating defects are developed. There are few reports on the simulation technique for under-film corrosion. S. Sakashita et al. performed onboard investigations of under film corrosion behavior of epoxy coated steel panels exposed in the un-immersed part of Water Ballast Tanks (WBT). N. Osawa et al. developed a coating degradation-metal corrosion coupling simulation method for epoxy coated steel panels in ship’s WBT. The onboard exposure tests of the scribed coated steel panels examined in the previous report were performed in the WBTs in which Shiotani and Tachibana measured the edge corrosion, and the test panel’s coating specification is the same as that of the WBT’s longitudinal members. The corrosive environment and coating specifications of the WBT in which Corrosion Resistant Steel was adopted are the same as those of the WBT in which the conventional steel was adopted.
