Copper anodes in an antifouling system release copper ions, while aluminium anodes produce aluminium hydroxide. Anode diameter and length are determined by seawater velocity or inlet flow rate, the intended design life and the maintenance or vessel dry-docking schedule. Anodes can be installed using auxiliary equipment such as steel flanges and sleeves.

Insulated copper cable provides the electrical connection to the anode. A cable lug connects it to the steel core inside the anode. The connection is carefully insulated to prevent short circuits.

Depending on the application and installation location, sealing these anodes requires particular care and specialist sealing materials during manufacture. Electrical continuity between cable and anode, and insulation of the flange and other mounting equipment from the anode and cable, must be checked after manufacture and before and after installation.
