Wärtsilä’s Aquarius UV and Aquarius EC ballast water management systems (BWMS) have been granted compliance with revised IMO guidelines by class society DNV GL on behalf of the Norwegian Maritime Authority.

While certifying compliance with the IMO’s Resolution MEPC.300(72) for the Approval of Ballast Water Management Systems (BWMS Code), DNV GL also awarded the system Type Approval status. The certifications were awarded in March and June respectively.

Compliance with the IMO Resolution (the Revised G8) is important for ship owners globally. All vessels installing a BWMS from 28 October 2020 will need to comply with the international BWMS Code.

“We are excited to have yet another approval in place for both Aquarius systems. It represents peace of mind for ship owners and operators knowing that it has been tested and approved to the highest operational and environmental standards,” says Arto Lehtinen, Director Water & Waste, Wärtsilä.

The Wärtsilä UV system is based on filter ultraviolet disinfection. It has already been awarded Type Approval under the original guidelines by the IMO and by the United States Coastguard (USCG), as well as Ex Certification by Dekra Exam GmbH and Lloyds Register Design Approval.

The Wärtsilä EC system is based on filter side-stream electro-chlorination. It too has IMO & USCG Type Approval, Ex Certification by Dekra Exam and Lloyds Register Design Approval.
