The Ballast Water Management (BWM) convention has not met its final entry-into-force requirement yet, the International Maritime Organization said.

Together with partner IHS Maritime & Trade, IMO has been engaged in a process to verify tonnage figures to ascertain whether or not the BWM convention’s requirement has been met, and, although the process will continue for up to three more weeks, IMO said that it is in a position to confirm that “the November ratifications did not trigger the convention’s entry into force.”
