Cathelco seawater pipework anti-fouling (AF) systems are designed to prevent blockages in seawater lines caused by the growth of barnacles and mussels.

The system has been successfully applied to all types of offshore structures including oil rigs, oil platforms, semi-submersible and jack-up rigs using seawater for cooling or emergency fire fighting purposes.
