The Evac Evolution Ballast Water Management System (BWMS) said that it has been granted IMO Type Approval. The system has been designed and manufactured by Cathelco. The system has been tested to the latest IMO requirements which include the revised G8 standard and the recently introduced Ballast Water Management Code.
What is more, Evac claimed that the Evac Evolution BWMS is also well on its way to receiving US Coast Guard Type Approval, as it is on the pending list since November 2018.

The latest test program was carried out at the MEA facility in Holland with Lloyd’s Register being the independent laboratory working under the Flag State regulations of the UK’s Marine & Coastguard Agency.
The company also noted that when the USCG rejected the IMO’s ruling on the acceptability of ‘viable’ life forms in favour of ‘non-viable’, Cathelco redesigned the system and started another round of testing.
The Evac Evolution BWMS has a feedback ‘loop’ based on the measurement of UV transmission which determines precise dosage. It also automatically adjusts to different seawater qualities in harbours and estuaries. The system is available in capacities from 34m3/h to 1,500m3/h in a single unit, while it can also be supplied skid mounted or in modular form.
Commenting on the technology, Robert Field, Cathelco technical director, said that it meets IMO standards regarding flow rates, sediment loads on filters and closer examination of the efficacy of the system in comparison with holding times.
