At its 71st meeting, the IMO Marine Environment Protection Committee (MEPC) agreed on an amendment to change the 2004 International Convention for the Control and Management of Ships’ Ballast Water and Sediments.

The amendment changes the implementation dates for the so-called D-2 discharge standard.

New compliance dates for ballast water discharge means that ships constructed on or after 8 September 2017 need to comply with the D-2 standard upon delivery, while existing ships in general must comply by the first IOPP renewal after 8th September 2019.

This new resolution is expected to be formally adopted at the next meeting of the IMO MEPC in April 2018.

At the meeting IMO MEPC furthermore agreed to ensure full global implementation by 8 September 2024.

The Ballast Water Management Convention has already been ratified by 61 countries, representing 68.46% of world merchant shipping tonnage.
As a result of the IMO Ballast Water Management Convention and the separate USCG ballast water regulations, it’s estimated that tens of thousands of vessels worldwide will require the installation of ballast water management system to meet the requirements of the convention.

The expected global ballast water management system market size is estimated to be between $18 billion and $28 billion, and will affect approximately 64.000 ships.
