First BWM system certified under new IMO guidelines

Several months of testing and just one new sensor later, Alfa Laval's PureBallast 3 is the first BWMS certified under revised G8 guidelines Several months of testing and just one new sensor later, Alfa Laval's PureBallast 3 is the first BWMS certified under revised G8 guidelines

Alfa Laval’s PureBallast 3 has become the first system to be type approved under revised IMO guidelines.

The more stringent testing requirements under the G8 guidelines – which will shortly become a mandatory code – were agreed by the IMO’s Marine Environment Protection Committee in 2016. Alfa Laval was issued with an updated IMO type approval certificate in line with the new guidelines by DNV GL, acting on behalf of the Norwegian Maritime Authority.

“Our customers require future-proof solutions, which is why certification in compliance with the revised G8 guidelines has been a high priority for Alfa Laval,” said Anders Lindmark, head of Alfa Laval PureBallast. “Ship owners can be fully confident that PureBallast 3 offers the performance to secure their compliance and protect our environment.”

The robust G8 guidelines are intended to be more in line with stringent US Coast Guard requirements. They were called for after some systems type approved according to the original guidelines subsequently failed to meet the discharge standards when subjected to additional tests or evaluation.

Ballast water treatment systems approved under the former guidelines can be installed until 2020, and no changes to systems already installed will be necessary required. But Alfa Laval argues readiness for revised G8 compliance shows PureBallast is a robust solution that will let ship owners make the most of their investment.

Only a single sensor was added to the PureBallast 3 hardware to enable the new certification, and no changes were made to its power consumption or flow.
