7 For ships constructed before 1 January 2007 and certified to carry substances in category Z anunderwater discharge outlet as required under paragraph 6 of this regulation is not mandatory.8 The underwater discharge outlet (or outlets) shall be located within the cargo area in the vicinity ofthe turn of the bilge and shall be so arranged as to avoid the re-intake of residue/water mixtures bythe ship’s seawater intakes.9 The underwater discharge outlet arrangement shall be such that the residue/water mixturedischarged into the sea will not pass through the ship’s boundary layer. To this end, when thedischarge is made normal to the ship’s shell plating, the minimum diameter of the discharge outletis governed by the following equation:whered = Q d /5L dd = minimum diameter of the discharge outlet (m)L d = distance from the forward perpendicular to the discharge outlet (m)Q d = the maximum rate selected at which the ship may discharge a residue/water mixture throughthe outlet (m 3 /h).10 When the discharge is directed at an angle to the ship’s shell plating, the above relationship shall bemodified by substituting for Q d the component of Q d which is normal to the ship’s shell plating.11 Slop tanksAlthough this Chapter does not require the fitting of dedicated slop tanks, slop tanks may be neededfor certain washing procedures. Cargo tanks may be used as slop tanks.Part 5 – Operational discharges of residues of noxious liquid substancesM Regulation 13 – Operational discharges of noxious liquid substancesAttention is drawn to the fact that the following regulation is the Danish Maritime Authority’stranslation of MARPOL.

1.2 Before any prewash or discharge procedure is carried out in accordance with this regulation,the relevant tank shall be emptied to the maximum extent in accordance with the proceduresprescribed in the Manual.1.3 The carriage of substances which have not been categorized, provisionally assessed orevaluated as referred to in regulation 6 of this Chapter or of ballast water, tank washings orother mixtures containing such residues shall be prohibited along with any consequentialdischarge of such substances into the sea.2 Discharge standards2.1 Where the provisions in this regulation allow the discharge into the sea of residues ofsubstances in category X, Y or Z or of those provisionally assessed as such or ballast water,tank washings or other mixtures containing such substances, the following dischargestandards shall apply:2.1.1 the ship is proceeding en route at a speed of at least 7 knots in the case of selfpropelledships or at least 4 knots in the case of ships which are not self-propelled;2.1.2 the discharge is made below the waterline through the underwater discharge outlet(s)not exceeding the maximum rate for which the underwater discharge outlet(s) is (are)designed; and2.1.3 the discharge is made at a distance of not less than 12 nautical miles from the nearestland in a depth of water of not less than 25 metres.2.2 For ships constructed before 1 January 2007 the discharge into the sea of residues ofsubstances in category Z or of those provisionally assessed as such or ballast water, tankwashings or other mixtures containing such substances below the waterline is notmandatory.2.3 The Administration may waive the requirements of paragraph 2.1.3 for substances incategory Z, regarding the distance of not less than 12 nautical miles from the nearest land forships solely engaged in voyages within waters subject to the sovereignty or jurisdiction ofthe State the flag of which the ship is entitled to fly. In addition, the Administration maywaive the same requirement regarding the discharge distance of not less than 12 nauticalmiles from the nearest land for a particular ship entitled to fly the flag of their State, whenengaged in voyages within waters subject to the sovereignty or jurisdiction of one adjacentState after the establishment of an agreement, in writing, of a waiver between the two coastalStates involved provided that no third party will be affected. Information on such agreementshall be communicated to the Organization within 30 days for further circulation to theParties to the Convention for their information and appropriate action if any.3 Ventilation of cargo residuesVentilation procedures approved by the Administration may be used to remove cargo residues froma tank. Such procedures shall be in accordance with appendix 7 of this Chapter. 9) Any watersubsequently introduced into the tank shall be regarded as clean and shall not be subject to thedischarge requirements in this Chapter.4 Exemption for a prewashOn request of the ship’s master, an exemption for a prewash may be granted by the Government ofthe receiving Party, where it is satisfied that:9) Please refer to Appendix 7 of MARPOL Annex II.15
