Ballast Water: Countdown to 8 September

The Ballast Water Convention will come into force on 8 September 2017, some 13 years after it was adopted at the IMO. The convention seeks to stop the spread of harmful aquatic organisms from one region to another via a ship's ballast water. Singapore and the Bahamas, the most recent parties to ratify the treaty (on 8 June), brought the number of countries party to the convention to 59, representing 65.18% of global shipping tonnage. Given that more than 40,000 ships will have to install ballast water treatment systems, shipowners and operators want insight into the cost and operational implications of complying with the convention.
