Danish company BAWAT has secured IMO Type Approval from Lloyd’s Register for a pasteurisation treatment system.

Lloyd’s Register issued the certification for the technology on behalf of the Danish Maritime Authority.

The treatment system uses a ship’s waste heat from the main engine or other heat sources to neutralise any organisms in the ballast water through pasteurisation.

It is one of the first systems to be tested and issued with approval under the new strict requirements of the IMO’s BWMS Code, officially known as the Code for Approval of Ballast Water Management Systems.

All vessels are required to have a ballast water treatment system to meet the D2 standards.

BAWAT managing director Marcus Hummer said: “To be one of the first systems to be awarded type approval under these new tougher conditions is a confirmation of the hard work we have put into what is the most sustainable treatment system on the market.

“It gives our customers the confidence that we have a product for their future needs.”

The system does not require any chemicals, filters or energy-consuming ultra-violet lights and uses pasteurisation to treat ballast water in all water conditions.

The system heat exchangers and pumps are standard components that are found on board modern vessels.

Hummer added: “There are thousands of vessels that will require effective, simple and efficient solutions installed between now and 2024 when the last IMO deadline comes around.”
