Alfa Laval became the first ballast water management system (BWMS) supplier to reapply for US Coast Guard (USCG) type-approval September 21st after its first application was rejected in December.

Alfa Laval carried out their own research tests at DHI in Denmark and BallastTech-NIVA in Norway with official testing being commissioned from DHI with class DNV GL preparing a test report package. The class society is accredited as an independent laboratory by the USCG for this role.
