Circular

  1 The Maritime Safety Committee, at its ninety-third session, and the Marine Environment Protection Committee, at its sixty-sixth session, taking into account the 2014 amendments to SOLAS and the IBC Code with respect to the application of inert gas when carrying low-flashpoint cargoes on ships constructed on or after 1 January 2016, reviewed a proposal of the Sub-Committee on Pollution Prevention and Response (PPR), at its first session, to ensure the provision of further information when carrying cargoes that require oxygen-dependent inhibitors.

  2 The Committees agreed that the existing IBC Code paragraph 15.13.3.2, which requires the Certificate of Protection to state "whether the additive is oxygen-dependent" should be amended by a requirement that states "whether the additive is oxygen-dependent and if so, the minimum level of oxygen required in the vapour space of the tank for the inhibitor to be effective must be specified."

  3 This information provided on the Certificate of Protection should be taken into account in the operation of the inert gas system to ensure the oxygen level does not fall below the level indicated on the certificate.

  4 Member Governments are invited to bring the content of this circular to the attention of all interested parties.
