Seawater Pipework Anti-fouling Systems

Cathelco… world leaders in seawater pipework anti-fouling systems The problem of bio-fouling in pipework Cathelco is the world’s largest designer and manufacturer of marine pipework anti-fouling systems. The purpose of the Cathelco system is to prevent blockages in seawater cooling systems caused by various forms of marine growth, primarily barnacles and mussels. With a record of 20,000 installations over a period of more than 50 years, the company has amassed considerable experience in the problems associated with marine pipework bio-fouling and developed the expertise to solve them effectively....

How the Cathelco system operates The Cathelco system has proved to be an extremely effective and versatile system for eliminating blockages in seawater pipework caused by biofouling. The system is based on the electrolytic principle and usually consists of pairs of copper and aluminium anodes which are mounted in seachests or strainers and wired to a control panel. In the case of cupro-nickel pipework, a ferrous anode is used instead of the aluminium anode. In operation, the copper anode produces ions which are carried by the flow of seawater, creating an environment in which barnacles and mussels...

Types of anodes and mounting arrangements Anti-fouling systems for box coolers Seachest mounted system Cathelco has developed a range of anodes with mountings which enable them to be installed in the seachests or strainers of almost any type of vessel. Detailed drawings are supplied for every ship to assist in installation and ensure that the anodes are positioned for maximum effectiveness in the seawater flow. The size of the anodes is determined by the flow rates and their anticipated design life, taking into consideration the scheduled dry docking period. The anodes can be installed using...

Systems for commercial and cruise vessels Commercial vessels Cathelco seawater pipework anti-fouling systems are installed on the ships of more than 40 navies around the world. With their durable construction, Cathelco control panels are ideally suited to rigorous demands of the naval sector. This is combined with a range of anodes to serve the needs of both surface craft and submarines. Cathelco’s reputation has been built on providing seawater pipework anti-fouling systems for some of the largest fleets of commercial vessels in the world. With the ability to treat high volumes of sea water,...

Systems for smaller vessels By miniaturising control panels and anodes, Cathelco have brought the benefits of pipework anti-fouling technology to a wide variety of smaller craft including offshore supply vessels, workboats, small ferries and tugs. Many of these vessels operate continuously within in-shore waters where there is a much higher risk of bio-fouling. By fitting a Cathelco system and eliminating problems of blockages in seawater lines serving engine cooling systems, considerable savings can be made in fuel usage and maintenance costs.
