The objective of this study was to propose a design and maintenance integrated (DMI) approach for the corrosion protection (CP) system for large scale floating structures. In this DMI approach, potential measurement and numerical simulating analysis is mainly performed so as to suggest reasonable maintenance means for the CP system to secure the floating structure. It is expected that, with circulative operations of this DMI approach for some floating structures with similar CP systems, understanding for ageing behavior of the CP system will be nearer to the truth and then numerical simulating analysis gives more reliable prediction. As the beginning of such circulative operations of this DMI approach, in this paper a chasing simulating analysis for the CP system of a floating oil stock tank was carried out. From the results of this chasing simulating analysis, trend of the CP system and some essential correlations were clarified. Therefore, a reasonable guideline for operating a protection potential monitoring system during a long time can be suggested.
