Currently, around 25% of the fleet in international voyage already has a ballast water treatment system (BWMS), D-2 standard. The rest of the fleet, about 75%, complies with the D-1 standard (ballast water exchange). As the updated BWM Convention is approaching, shipowners are making the necessary preparations to comply.
About the BWM Convention
Following the UN Conference on Environment and Development (UNCED), held in Rio de Janeiro in 1992, the IMO initiated negotiations to consider the possibilities of developing an internationally binding instrument to address the transfer of harmful aquatic organisms and pathogens in ships’ ballast water. From 1999 onwards, the Ballast Water Working Group, established by the MEPC in 1994, focused on the preparation of a free-standing Convention on control and management of ships’ ballast water and sediments.
The introduction of harmful aquatic organisms and pathogens to new environments had been identified as one of the four greatest threats to the world’s oceans (the other three being land-sourced marine pollution, overexploitation of living marine resources and destruction of habitat) and in 2002 the World Summit on Sustainable Development held in Johannesburg called for action at all levels to accelerate the development of measures to address invasive aquatic species in ballast water.
Proper control and management of ships’ ballast water became a major environmental challenge for BWM Convention 2009 photo.jpgIMO and the global shipping industry. At its eighty-ninth session in November 2002, the Council approved the convening of the Diplomatic Conference in early 2004. The decision of the Council was endorsed by the twenty-third session of the Assembly in December 2003 and the International Conference on Ballast Water Management for Ships’ was held at IMO’s Headquarters in London from 9 to 13 February 2004. The Conference adopted the International Convention for the Control and Management of Ships’ Ballast Water and Sediments (the Ballast Water Management Convention), together with four conference resolutions.

At its seventy-second session in April 2018, MEPC adopted amendments to the Convention, which will enter into force in October 2019. The amendments are:
.1 amendments to regulations A-1 and D-3 of the BWM Convention to make the BWMS Code mandatory (resolution MEPC.296(72));
.2 amendments to regulation B-3 of the BWM Convention, concerning the implementation schedule of ballast water management for ships (resolution MEPC.297(72)), along with a resolution relating to the determination of the survey referred to in regulation B‑3 (resolution MEPC.298(72)); and
.3 amendments to regulations E-1 and E-5 of the BWM Convention, concerning endorsements of additional surveys on the International Ballast Water Management Certificate (resolution MEPC.299(72)).
MEPC 72 also adopted the BWMS Code (resolution MEPC.300(72)), which will supersede the 2016 Guidelines for approval of ballast water management systems (G8) from October 2019.
Further amendments to the BWM Convention may occur now that the Convention is in force, including a possible comprehensive set of amendments after the ballast water experience‑building phase (EBP) (resolution MEPC.290(71)). Taking into consideration that challenges may arise during the implementation of any new convention that were not foreseen at the time of its adoption, the EBP was established by MEPC at its seventy-first session in July 2017 as a means for carrying out a systematic and evidence-based review of the BWM Convention.BWM Guidelines
Several articles and regulations of the Ballast Water Management Convention refer to guidelines to be developed by the Organization and Conference resolution 1 invites IMO to develop these guidelines as a matter of urgency and adopt them as soon as practicable, and in any case before the entry into force of the Convention, with a view to facilitate global and uniform implementation of the instrument.
In a commendable effort to facilitate the process, the IMO Member States have developed 14 sets of Guidelines from July 2005 to October 2008, some of which have since been further revised. This outstanding and probably unique output in the working history of MEPC, would have not been possible without the dedication of the BWWG and the technical support of the BLG, FSI and DE Sub-Committees.
It should be noted that, due to the complexity and multi-disciplinary nature of the problem posed by invasive aquatic species in ships' ballast water, the work is in its pioneering phase and knowledge is only now gathering in this respect. The Guidelines are kept under review by the MEPC and updated as new technologies emerge and additional knowledge becomes available.
The following is the up-to-date list of Guidelines relating to the uniform implementation of the BWM Convention that have been developed, adopted and, in some cases, revised since MEPC 53:
- Guidelines for sediment reception facilities (G1) (resolution MEPC.152(55));
- Guidelines for ballast water sampling (G2) (resolution MEPC.173(58));
- Guidelines for ballast water management equivalent compliance (G3) (resolution MEPC.123(53));
- Guidelines for ballast water management and development of ballast water management plans (G4) (resolution MEPC.127(53));
- Guidelines for ballast water reception facilities (G5) (resolution MEPC.153(55));
- 2017 Guidelines for ballast water exchange (G6) (resolution MEPC.288(71));
- 2017 Guidelines for risk assessment under regulation A-4 of the BWM Convention (G7) (resolution MEPC.289(71));
- 2016 Guidelines for approval of ballast water management systems (G8)
- (resolution MEPC.279(70)) (this will be superseded by the BWMS Code (resolution.300(72)) in October 2019);
- Procedure for approval of ballast water management systems that make use of Active Substances (G9) (resolution MEPC.169(57));
- Guidelines for approval and oversight of prototype ballast water treatment technology programmes (G10) (resolution MEPC.140(54));
- Guidelines for ballast water exchange design and construction standards (G11) (resolution MEPC.149(55));
- 2012 Guidelines on design and construction to facilitate sediment control on ships (G12) (resolution MEPC.209(63));
- Guidelines for additional measures regarding ballast water management including emergency situations (G13) (resolution MEPC.161(56));
- Guidelines on designation of areas for ballast water exchange (G14) (resolution MEPC.151(55));
- Guidelines for ballast water exchange in the Antarctic treaty area (resolution MEPC.163(56)); and
- Guidelines for port State control under the BWM Convention (resolution MEPC.252(67)).
