INTERNATIONAL CONVENTION FOR THE CONTROL 

AND MANAGEMENT OF SHIPS’ BALLAST WATER 

AND SEDIMENTS, 2004

List of ballast water management systems that make use of Active Substances 

which received Basic and Final Approvals 

1 The Ballast Water Management Convention (BWM Convention) provides in its 

regulation D-3.2 that ballast water management systems which make use of Active Substances, 

to comply with the Convention, shall be approved by IMO based on a procedure developed by 

the Organization. According to regulation A-1.7 of the same Convention, an Active Substance is a 

substance or organism, including a virus or a fungus, that has a general or specific action on or 

against harmful aquatic organisms and pathogens. 

2 The Marine Environment Protection Committee (MEPC), at its fifty-third 

session (18 to 22 July 2005), adopted the “Procedure for approval of ballast water management 

systems that make use of Active Substances (G9)” by resolution MEPC.126(53). At the same 

session, MEPC established a Technical Group (GESAMP-Ballast Water Working Group) under the 

auspices of GESAMP∗

, to evaluate Active Substances and the relevant systems and advise the MEPC 

accordingly. 

3 MEPC 57 (31 March to 4 April 2008) adopted resolution MEPC.169(57), which revokes 

resolution MEPC.126(53) and contains the revised “Procedure for approval of ballast water 

management systems that make use of Active Substances (G9)”. 

4 Section 8 of Procedure (G9) sets out the methodology to be followed for the two-tier 

approval of ballast water management systems that make use of Active Substances and requests IMO 

to record the Basic and Final Approvals and to circulate the list once a year. 

5 Following the consideration of the relevant reports of the GESAMP-BWWG, the MEPC, at its 

fifty-ninth session (13 to 17 July 2009), granted three Basic Approvals and four Final Approvals to the 

ballast water management systems that make use of Active Substances. The annexes to this 

circular contain relevant information on the ballast water management systems that 

received Basic and Final Approvals from March 2006 until December 2009. 

6 This circular supersedes Circular BWM.2/Circ.16. 

 

* GESAMP stands for IMO/FAO/UNESCO-IOC/WMO/IAEA/UN/UNEP/UNIDO Joint Group of Experts on 

the Scientific Aspects of Marine Environmental Protection.

7 Information regarding the systems that received Type Approval Certification can be found in 

the IMO website at http://www.imo.org/home.html. 

8 Member Governments are invited to bring this circular to the attention of all the parties 

concerned.
