Impressed Current Cathodic Protection Scheme Impressed Current Cathodic Protection (ICCP) Scheme is the most environmentally friendly method for offshore wind farm/oil drilling platform. External current can provide better protection and control, and can also be monitored by Internet. Compared with sacrificial anode, the cost of external current scheme is lower, and its long-term service life can reach more than 20 years. For ecologically sensitive marine areas, the protection of endangered marine organisms is relatively advantageous. Summarize the advantages of external current: 1. Cheaper than sacrificial anode 2. Low weight 3. SCADA monitoring 4.30 years or longer life 5. Environmental protection. (Figure: CWC Netherlands)
