Annex – Amendments to the Unified Interpretation to Regulation 12.2 of MARPOL Annex I

  1 The existing Unified Interpretation to regulation 12.2 should read as an interpretation to regulation 12.2.1.

  2 A new Unified Interpretation to regulation 12.2.2 is added as follows:

  • Regulation 12.2.2 – Sludge tank discharge piping

  • 1 Regulation 12.2.2 should not be retroactively applied to ships delivered before 1 January 2014footnote.

  • 2 There should be no interconnections between the sludge tank discharge piping and bilge-water piping other than possible common piping leading to the standard discharge connection referred to in regulation 13.

  • 3 For ships delivered before 1 January 2014footnote, existing arrangements where the oil residue (sludge) tank(s) have discharge connections to oily bilge water holding tank(s), tank top or oily water separator may be accepted.

  • 4 Screw-down non-return valves arranged in lines connecting to common piping leading to the standard discharge connection required by regulation 13, to prevent sludge from discharging to the bilge system, oily bilge water holding tank(s), tank top or oily water separators, provide a means equivalent to an arrangement that has "no interconnection" or "no discharge connections" as so specified in regulation 12.2 and the Unified Interpretation referenced by paragraph 2.

  • 5 It is understood that the common piping may serve only one purpose and that is to connect the discharge lines of the bilge and sludge pumps to the standard discharge connection referred to in regulation 13, or any other approved means of disposal.
