SGS Global Marine Services group, with a long history of marine, environmental testing, conducts commissioning testing of ballast water management systems (BWMS) to determine compliance to the International Maritime Organization (IMO) D-2 discharge standard following the commissioning guidelines as set out in BWM.2/Circ.70. This white paper summarizes data collected from 95 ships. Of these BWMS tested, some were tested on a single ship (multiple BWMS installed), and some were tested multiple times (e.g. re-tested after an initial failure to comply with the discharge standard).
