Seawater intakes

Electrolytic antifouling reduces marine growth in sea chests and sea water intakes.

Anode rods in sea chests

The anode rods (copper and aluminium or iron) are preferentially installed in the sea chests to treat the seawater before entering the piping system. Such location will also reduce the marine fouling in the sea chest.

Anode rods in strainers

The antifouling anodes may also be installed in the strainers, either in addition to or as an alternative to location in sea chests. The reason for installing anodes in strainers is normally lack of space in sea chest, required anifouling boosting effect or need for anode replacement during vessel operation.

Cathodic protection effect

As a result of the DC current impressed through the antifouling anodes to the steel work, the sea chest will be cathodically protected. Hence, the number of sacrificial anodes are reduced or eliminated.
