Cathelco marine growth prevention 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.


Systems on frigates usually involve a combination of seachest and strainer mounted anodes. As with most military vessels, the pipework is predominantly cupro-nickel and therefore pairs of copper and ferrous anodes are used to provide effective anti-fouling and corrosion suppression. Read more

Recent contracts for frigates and warships include equipment for the BAM project in Spain, PVO and BVL projects in Venezuela and the FREMM project involving the Italian and French Navy.

These installations involve the treatment of large volumes of seawater using multi-anode installations serving numerous inlets covering the requirements of engine cooling water systems, refrigeration, air conditioning and fire fighting systems.

Cathelco are proud to have supplied equipment for the HMS Queen Elizabeth and HMS Prince of Wales, the Royal Navy’s two new 65,000 tonne aircraft carriers.

Fast patrol craft

Cathelco have considerable experience in the design of pipework anti-fouling systems for fast patrol craft where space is at a premium. These vessels generally have a number of small inlets which can be protected with compact dual purpose anodes, consisting of copper/aluminium or ferrous elements in a single assembly.

Alternatively, miniaturised Nano anodes can be fitted in strainers. The Cathelco Mini and Nano control panels ensure that systems can be installed in the tightest areas within engine rooms. Read more

The Cathelco system was originally designed for use on submarines and the company regularly supplies anti-fouling equipment to some of the world’s leading builders of submarines including Kockums, HDW, TNSW and the Australian Submarine Corporation.

Because of space restrictions within strainers, installations are usually based on compact dual purpose anodes. Systems are often specially designed to meet the exact requirements of particular classes of submarines.
