protect your vessel from harmful biofouling
What is marine growth prevention?
Marine growth prevention eliminates the settlement of macro biofouling organisms on the ship’s interior piping systems, thus creating less waste due to the longer lifecycle of the pipes.
Our Cathelco® marine growth prevention systems (MGPSs) for seawater pipework are easy and economical to install, and they can be found on more than 50,000 ships worldwide. Designed to eliminate blockages caused by barnacle and mussel growth in seawater cooling lines, the systems are available for vessels of every size including mini systems for luxury yachts.
How does marine growth prevention work?
Marine growth prevention systems (MGPSs), also known as antifouling systems, usually consist of pairs of copper and aluminium anodes, mounted in sea chests or strainers and connected to a control panel. In operation, the copper anode produces ions that are carried by the flow of seawater, creating an environment where barnacles and mussels will not settle or multiply.
By introducing copper ions in very small concentrations, around two parts per billion, the system interrupts the settlement sequence of mussel and barnacle larvae. Instead of adhering to the surface of sea chests, strainers, and pipework, the larvae pass harmlessly through the cooling water system to the discharge point. Without antifouling protection, pipes can become encrusted with organisms, leading to a blockage that reduces the efficiency of the seawater cooling system.
Why choose Cathelco® products?
