IMO Convention on Ballast Water Management Ratified - What's Next?

Last week in Law at the Waterline, we celebrated the ratification of the IMO convention on ballast water management, an event we described as “a major milestone for enhanced protection of our oceans and a profound business driver for marine-environmental technology.”  As we progress to towards the convention’s permanent implementation date of September 8, 2017, Law at the Waterline will have a series of posts tracking this process and progress of implementation, including type approval and other standards for treatment technologies and developments expected in the U.S. Coast Guard’s promulgation of its requirements. We begin the series this week with some background information in a post by Grace Denny, a student at Boston College.

IMO Ballast Water Treatment Study Extended

The IMO (International Maritime Organization) study on the implementation of the Regulation D-2 of the BWM Convention ballast water performance standard will assess the implementation of the Guidelines for approval of ballast water management systems (G8) and related type approval processes, as well as the performance of approved ballast water management systems (BWMS) in routine operation on board ships.

The Study involves online surveys and document collection  on current and past approaches and procedures used in testing of BWMS and the granting of Type Approval Certificates by Administrations, “Track 1”. “Track 2” also involves online surveys and data collection on the technical, mechanical and biological performance of BWMS with Type Approval Certificates that have been installed, commissioned and are in operation on board ships.

The goal of both tracks is to collect facts on BWMS operational performance and not to suggest what is “acceptable” or “best”.

The deadline for participation by supplying comments has been extended to 10 June, 2015. For further information and how to submit comments, see:


Full Acceptance of International Ballast Water Requirements for Ships Nears: Japan’s Accession Puts Full Ratification Within Less Than 3%

On October 10, Japan deposited its accession to the Ballast Water Management (BWM) Convention 2004 with the International Maritime Organization (IMO). A total of 42 states have now signed up to the convention, representing 32.02% of the required 35% of the world merchant tonnage, placing the Convention 2.98% away from full ratification. The Convention, once fully ratified, will trigger mandatory requirements that will address the problem of invasive species being transported around the world in ships’ ballast water.
