What Cathelco does
Cathelco is a UK-based maritime engineering company founded in 1956 that designs and supplies biofouling management, corrosion protection, and onboard fresh water generation systems for naval, commercial, and offshore operators. Its products span four technology families: copper and aluminium anodic impressed-current cathodic protection (ICCP) systems and MGPS pipework dosing for corrosion and biological fouling control; the newly launched USP DragGone ultrasonic antifouling platform, which uses patented Guided Wave and Heterodyning dual-frequency cavitation to disable marine organisms without biocides; and Seafresh reverse osmosis desalinators that produce freshwater from seawater for vessel consumption. The company also offers subscription-based hull performance monitoring layered on top of its hardware installed base. Cathelco operates as a brand within the Evac group, supplying directly to shipyards, navies, and ship owners through a combination of direct field sales and a global service network with local production, generating revenue from upfront equipment sales, recurring spares and service contracts, and aftermarket monitoring subscriptions. Its customer base spans 40+ navies and more than 20,000 vessels cumulatively, with 1,800+ desalinator units installed.
