Following Morocco, Indonesia and Ghana's ratification of the Ballast Water Management Convention this week, the International Maritime Organization (IMO) has announced an unprecedented review of registered tonnage of the global fleet. The purpose of the review is to see whether Morocco, Indonesia and Ghana's combined tonnage is sufficient to take the total tonnage of the world fleet associated with states which have ratified the convention over the threshold of 35 per cent. If so, the Ballast Water Management Convention will enter into force next year, possibly as early as 24 November 2016. The IMO secretariat has confirmed that they do not know how long this checking process will take.

Finland has also announced its intention to ratify the Ballast Water Management Convention.  Therefore it appears that the threshold may soon be reached, even if the ratification by Morocco, Indonesia and Ghana is not found to breach the 35% barrier.
