On 25 June the US Coast Guard issued its latest and the 20th Ballast Water Management System Type Approval Certificate to Cathelco, after a detailed review of the manufacturer’s type approval application for its Evolution system determined it met the requirements of 46 CFR 162.060.

Cathelco

The system was granted IMO type approval in May 2014. In 2018, Cathelco was acquired by the Finland-headquartered Evac Group and the system is now marketed as Evac Evolution.

The treatment principle of the Evolution system consists of filtration with UV treatment during uptake and discharge. This approval covers models with maximum treatment rated capacities between 55m3/h and 1,500m3/h.

As a UV system the Evolution range is not limited by salinity but of at least 48 hours and must have a UV transmittance of above 55%. It has not been approved for use in hazardous locations.

The type approval of the system means that there are now six other systems with completed applications awaiting approval.
