The US Coast Guard (USCG) has granted its second and third ballast water management system (BWMS) type approvals.
USCG announced that Alfa Laval’s PureBallast 3 system and OceanSaver’s BWTS MKII have been granted certification.
This initial approval only covers those systems which use the tested UV reactor sizes of 300 and 1000. Future approval of the 170 and 600 reactors is dependent on Coast Guard approval of the UV reactor scaling studies, which are currently under review by the Marine Safety Center.
The two approvals follow the granting of the first USCG type approval for BWMS to Norwegian manufacturer Optimarin.
