Our solutions for navy and coast guard vessels

Evac solutions can be found on hundreds of different types of naval vessel around the globe, from simple patrol boats to the unique challenges of submarines and the latest aircraft carriers.

Our naval portfolio focuses on military requirements and reliable construction. Shock, vibration, airborne and structural noise, and electromagnetic interference (EMI) requirements are all challenges we can help you solve. We also guarantee reliable deliveries, comprehensive documentation, and effective aftersales support.

System size and weight are typically the limiting factors in naval projects. We meet these challenges by offering a wide range of compact products. We also have our own product development specialists who can design a totally customer-specific solution that meets your exact needs.

Marine growth prevention systems

Cathelco marine growth prevention systems are installed on the ships of more than 40 navies around the world. With their durable construction, our 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.

Aircraft carriers

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.

Fast patrol craft

We 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.


Our 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.

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.
