Technology description

New EU biocide regluations

As of September 2015, owners and operators of vessels sailing in European waters must ensure that their marine growth prevention systems comply with the EU Biocides Regulation 528/2012. Cathelco is one of the few companies listed under Article 95, the official register of approved active substance suppliers recognized by the European Chemicals Agency (ECHA). This makes installing genuine Cathelco equipment and anodes a safe way to ensure regulatory compliance.

Failure to use equipment from an authorized supplier may affect a ship’s Green Passport, leading to financial penalties and even imprisonment.
