The Maritime Safety Committee

  1 Ballast water carried in ships to maintain safety and stability has been recognized as one of the major pathways for the transfer of harmful aquatic organisms and pathogens around the world. This threat to the aquatic environment has been acknowledged by the Convention on Biological Diversity, 1992, in Article 196 of the United Nations Convention on the Law of the Sea, 1982, and by other relevant international agreements.

  2 A draft international convention for the control and management of ship's ballast water and sediments as well as associated guidelines for its implementation is being developed for consideration and adoption by a diplomatic conference in 2003. This is based on resolution A.868(20) concerning the Guidelines for the control and management of ship's ballast water to minimize the transfer of harmful aquatic organisms and pathogens.

  3 The paramount importance of the safety of a ship is acknowledged when developing ballast water management measures to prevent, reduce and eliminate the transfer of harmful aquatic organisms and pathogens.

  4 It was agreed that it is essential to continue the development of safer and more effective Ballast Water Management options that will result in continued reduction and eventual elimination of the transfer of harmful aquatic organisms and pathogens.

  5 The Maritime Safety Committee at its seventy-fourth session (May 2001) and the Marine Environment Protection Committee at its forty-seventh session (March 2002) emphasized the need for ballast water and sediment management options to be taken into account when designing and building new ships, while noting that the future convention might require the development of ballast water management plans both for new and existing ships and approved the Guidance on “Design Suggestions for Ballast Water and Sediment Management Options in New Ships”, as set out in the annex hereto.

  6 Member Governments are invited to apply the annexed Guidance until the International Convention for the Control and Management of Ships' Ballast Water and Sediments is adopted and enters into force, to bring the Guidance to the attention of ship-builders, ship-owners, shipmasters and other parties concerned. Member Governments are also invited to inform the Organization on any experience gained in the implementation of this Guidance.
