    A new method for forecasting the current of sacrificial anodes using data assimilation was developed. In our system, In the framework of data assimilation, the system model forecasts the future state by the technical knowledge gained from experiments. The observation model corrects the forecasted result by the measurement information. In order to demonstrate the effectiveness and efficiency of our system, the verification experiment was performed at the real marine steel structures. The proposed method is expected to be a new approach for corrosion protection maintenance.

    To maintain economically steel structures against corrosion damage, it is necessary to quantitatively clarify the corrosion environments of individual parts in the structures and to evaluate the time-dependent corrosion behavior. In this research, an evaluating method for the time-dependent corrosion depth of uncoated structural steel plates using Fe/Ag galvanic couple ACM type corrosion sensor was proposed. This method was focused on the environments with and without effect of rainfall and airborne sea salt. Atmospheric exposure tests were carried out on the uncoated steel plates in four fields in which the environments varied widely as a function of rainfall and airborne sea salt. In addition to this, the corrosive environments of the skyward- and groundward-facing surfaces of the plates were monitored using the ACM sensors.
