Development of the Forecasting System of the Current from Sacrificial Anodes of Marine Structures using Data Assimilation

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.
