Finnish-based Auramarine Ltd. has recently received an IMO type approval for its CrystalBallast ballast water treatment system. The approval was issued by DNV on behalf of the Norwegian Maritime Directorate after the successful land-based and shipboard testing in accordance with International Maritime Organisation’s (IMO) “Guidelines for approval of BWM Systems (G8)” and DNV rules. In addition, the electrical components were subjected to DNV’s “Environmental test specification for instrumentation and automation equipment, DNV Standard for Certification No 2.4”. These requirements are more stringent than the IMO requirements and include, for instance, also electromagnetic compatibility (EMC), vibration, low temperatures and damp heat testing.
