When Barney the Barnacle feels this big,
Cathelco brings him under control.
Marine growth prevention, ultrasonic antifouling and corrosion protection for your vessel.
Small organisms,
BIG CONSEQUENCES.

Meet Barney. He’s a barnacle with an inflated sense of his own importance. Though if you’ve dealt with marine growth on your vessel, his size might feel about right.
Barnacles and other marine growth have a way of making life on board more complicated than it needs to be. For something so small, they can get in the way of running a ship.
That’s why we’ve given the problem a face. Something you can size up, understand and get under control. Barney might look formidable. He doesn’t have to be.
Cathelco helps keep marine growth under control, protecting your vessel’s efficiency, reliability and day-to-day operation.
Keep Barney from
getting settled.
We’re big believers in preventing the problem before you’re left dealing with it. That’s why we developed Cathelco USP DragGone™. It uses ultrasound to help stop fouling taking hold, giving Barney fewer opportunities to make himself at home.
Wondering whether ultrasonic antifouling is right for your vessel? Our buyer’s guide explains how it works, what separates the technologies and what to ask before choosing a system.

Systems, spares & service
Your hull. Your pipework.
We’ve got you covered.
Choose protection for a new vessel, upgrade an existing installation or find the parts to keep your Cathelco system working.

Marine growth prevention
Keep your niche areas and seawater systems clear.
Cathelco MGPS helps prevent barnacles and other marine growth from establishing inside seawater intakes and pipework. Protect the flow needed for cooling and other essential onboard systems, with less fouling to deal with during maintenance.

USP DragGone™
Help stop hull fouling before it builds up.
Barnacles aren’t where fouling begins. USP DragGone™ targets early-stage microfouling with non-biocidal ultrasound, helping keep submerged surfaces cleaner and limit the build-up that adds drag.

Corrosion protection
Look after the hull beneath it all.
Barney can’t take the blame for everything. Cathelco impressed current cathodic protection (ICCP) systems help protect your vessel’s submerged metal surfaces against corrosion.
