The International Ballast Water Management Convention has been fully ratified, and will enter into force on September 8, 2017 (IMO, 2016), there is a pressing need:

  • For ships to plan installations of ballast water treatment systems, and
  • For regulators to plan the implementation of the Ballast Water Management Convention into their national legislation and Port State Control inspection programs.
