Sea Chest Cath Flow Anti-Fouling System: Protection against fouling and corrosion
The Sea Chest Cath Flow Anti-Fouling System is an innovative solution to combat fouling and corrosion on ship hulls. In the maritime sector, these problems are common and can have a significant impact on the performance and life of yachts. In this article you will learn more about how this system works and how it helps to increase the safety and efficiency of vessels.
The challenges of fouling and corrosion
Fouling, i.e. the adhesion of organisms such as algae, mussels and barnacles to ship hulls, can lead to increased flow resistance and thus to an increase in the fuel consumption of yachts. In addition, fouling can affect the speed and maneuverability of vessels and increase maintenance costs.
Corrosion is another problem that can attack the ship's hull and, in particular, the seacocks and the cooling system. The consequences are increased maintenance costs and a shortened service life of the affected parts.
How the Sea Chest Cath Flow Anti-Fouling System works
CathFlow® Electrolytic Antifouling suppresses corrosion and prevents the settlement of mussels, barnacles and similar organisms in seawater systems. The CathFlow® system releases antifoulants (ions) into seawater, creating an environment that reduces corrosion and prevents organisms from attaching, growing and reproducing. This efficient system thus protects marine structures and maritime equipment from damage caused by fouling and corrosion, and helps extend their service life.
Electrochlorination
By applying an electrical voltage to electrodes in the Sea Chest, salt water is converted into sodium hypochlorite. This chemical acts as a biocide and prevents marine organisms from adhering to the hull.
Cathodic protection
A small electrical voltage is applied to ship components to prevent corrosion. The voltage protects the metal by slowing or reversing the electrochemical corrosion process.
Advantages of the Sea Chest Cath Flow System
Environmental friendliness
Compared to traditional anti-fouling coatings that can contain harmful chemicals, the Sea Chest Cath Flow System is more environmentally friendly.
Cost efficiency
By preventing fouling and corrosion, maintenance costs and fuel consumption can be reduced, resulting in long-term cost savings.
