Technology description

New EU biocide regluations

Since September 2015, owners and operators of vessels sailing into European waters must ensure that marine growth prevention systems comply with the EU Biocides Regulation (528/2012). Cathelco are one of the few companies listed under Article 95, the official register of Authorised Active Substance suppliers who have been approved by the European Chemicals Agency (ECHA). Therefore, it is important to install genuine Cathelco equipment and anodes.

Failure to use equipment from an authorised supplier may affect the ship’s Green Passport, lead to financial penalties and even imprisonment.
