ICCP retrofit for an offshore jacket
The feasibility of using an ICCP system was investigated through computational modeling. First the asis CP status of the complex was simulated taking into account the current condition of the sacrificial anodes as observed during the latest survey. Secondly, an ICCP system was included in the model and different anode sled positions were investigated until an optimal design was obtained. The remaining life of the anodes was ecalculated such that the amount of anode sleds was kept to a minimum. Through modeling the CP effectiveness of the combined system was validated and a cost-effective solution was proposed.
