Distinctive number or letters:........................................................................... IMO Number .................................................................................................... Port of registry:................................................................................................ Approval stamp of Administration: 1973, as modified by the Protocol of 1978 relating thereto (hereinafter referred to as MARPOL 73/78) was established in order to prevent the pollution of the marine environment by discharges into the sea from ships of harmful substances or effluents containing such substances. In order to achieve its aim, MARPOL 73/78 contains six Annexes in which detailed regulations are given with respect to the handling on board ships and the discharge into the sea or release into the atmosphere of six main groups of harmful substances, i.e. Annex I (Mineral oils), Annex II Noxious Liquid Substances carried in bulk), Annex III (Harmful substances carried in packaged forms), Annex IV (Sewage), Annex V (Garbage) and Annex VI (Air Pollution). 2 Regulation 13 of Annex II of MARPOL 73/78 (hereinafter referred to as Annex II) rohibits the discharge into the sea of Noxious Liquid Substances of Categories X, Y or Z or of ballast water, tank washings or other residues or mixtures containing such substances, except in compliance with specified conditions including procedures and arrangements based upon standards developed by the International Maritime Organization (IMO) to ensure that the criteria specified for each Category will be met. 3 Annex II requires that each ship which is certified for the carriage of Noxious Liquid Substances in bulk shall be provided with a Procedures and Arrangements Manual, hereinafter referred to as the Manual. 4 This Manual has been written in accordance with Appendix 4 of Annex II and is concerned with the marine environmental aspects of the cleaning of cargo tanks and the discharge of residues and mixtures from these operations. The Manual is not a safety guide and reference shall be made to other publications specifically to evaluate safety hazards. 5 The purpose of the Manual is to identify the arrangements and equipment required to enable compliance with Annex II and to identify for the ship's officers all operational procedures with respect to cargo handling, tank cleaning, slops handling, residue discharging, ballasting and deballasting, which must be followed in order to comply with the requirements of Annex II. 6 In addition, this Manual, together with the ship's Cargo Record Book and the Certificate issued under Annex II* , will be used by Administrations for control purposes in order to ensure full compliance with the requirements of Annex II by this ship. 7 The master shall ensure that no discharges into the sea of cargo residues or residue/water mixtures containing Category X, Y or Z substances shall take place, unless such discharges are made in full compliance with the operational procedures * Include only the Certificate issued to the particular ship: i.e. The International Pollution Prevention Certificate for the carriage of Noxious Liquid Substances in bulk or the Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk or the International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk. INDEX OF SECTIONS 1 Main features of MARPOL 73/78, Annex II 2 Description of the ship's equipment and arrangements 3 Cargo unloading procedures and tank stripping 4 Procedures relating to the cleaning of cargo tanks, the discharge of residues, ballasting and deballasting 5 Information and Procedures SECTION 1 Main features of MARPOL 73/78, Annex II 1.1 The requirements of Annex II apply to all ships carrying Noxious Liquid Substances in bulk. Substances posing a threat of harm to the marine environment are divided into three categories, X, Y and Z. Category X substances are those posing the greatest threat to the marine environment, whilst Category Z substances are those posing the smallest threat. 1.2 Annex II prohibits the discharge into the sea of any effluent containing substances falling under these categories, except when the discharge is made under conditions which are specified in detail for each Category. These conditions include, where applicable, such parameters as: .1 the maximum quantity of substances per tank which may be discharged into the sea; .2 the speed of the ship during the discharge; .3 the minimum distance from the nearest land during discharge; .4 the minimum depth of water at sea during discharge; and .5 the need to effect the discharge below the waterline. 1.3 For certain sea areas identified as "special area" more stringent discharge criteria apply. Under Annex II the special area is the Antarctic area. 1.4 Annex II requires that every ship is provided with pumping and piping ΕΦΗΜΕΡΙΣ ΤΗΣ ΚΥΒΕΡΝΗΣΕΩΣ (ΤΕΥΧΟΣ ΠΡΩΤΟ) 239 quantity given in the Annex. For each tank intended for the carriage of such substances an assessment of the residue quantity has to be made. Only when the residue quantity as assessed is less than the quantity prescribed by the Annex a tank may be approved for the carriage of a Category X, Y or Z substances. 1.5 In addition to the conditions referred to above, an important requirement contained in Annex II is that the discharge operations of certain cargo residues and certain tank cleaning and ventilation operations may only be carried out in accordance with approved procedures and arrangements. 1.6 To enable the requirement of paragraph 1.5 to be met, this Manual contains in section 2 all particulars of the ship's equipment and arrangements, in section 3 operational procedures for cargo unloading and tank stripping and in section 4 procedures for discharge of cargo residues, tank washing, slops collection, ballasting and deballasting as may be applicable to the substances the ship is certified to carry. 1.7 By following the procedures as set out in this Manual, it will be ensured that the ship complies with all relevant requirements of Annex II to MARPOL 73/78.

ADDENDUM D - ADDITIONAL INFORMATION AND OPERATIONAL INSTRUCTIONS REQUIRED OR ACCEPTED BY THE ADMINISTRATION

PUMPS AND ASSOCIATED PIPING 1 Introduction 1.1 Purpose 1.1.1 The purpose of this appendix is to provide the procedure for testing the efficiency of cargo pumping systems. 1.2 Background 1.2.1 The ability of the pumping system of a tank to comply with regulation 12.1, 12.2 or 12.3 is determined by performing a test in accordance with the procedure set out in section 3 of this appendix. The quantity measured is termed the "stripping quantity". The stripping quantity of each tank shall be recorded in the ship's Manual. 1.2.2 After having determined the stripping quantity of one tank, the Administration may use the determined quantities for a similar tank, provided the Administration is satisfied that the pumping system in that tank is similar and operating properly. 2 Design criteria and performance test 2.1 The cargo pumping systems should be designed to meet the required maximum amount of residue per tank and associated piping as specified in regulation 12 of Annex II to the satisfaction of the Administration. 2.2 In accordance with regulation 12.5 the cargo pumping systems shall be tested with water to prove their performance. Such water tests shall, by measurement, show that the system meets the requirements of regulation 12. In respect of regulations 12.1 and 12.2 a tolerance of 50 litres per tank is acceptable. 3 Water performance test 3.1 Test condition 3.1.1 The ship's trim and list shall be such as to provide favourable drainage to the suction point. During the water test the ship's trim shall not exceed 3° by the stern, and the ship's list shall not exceed 1°. 3.1.2 The trim and list chosen for the water test shall be recorded. This shall be the minimum favourable trim and list used during the water test. 3.1.3 During the water test means shall be provided to maintain a back-pressure of not recognizing that this may need to be amended as a result of subsequent tests. 3.2 Test procedure 3.2.1 Ensure that the cargo tank to be tested and its associated piping have been cleaned and that the cargo tank is safe for entry. 3.2.2 Fill the cargo tank with water to a depth necessary to carry out normal end of unloading procedures. 3.2.3 Discharge and strip water from the cargo tank and its associated piping in accordance with the proposed procedures. 3.2.4 Collect all water remaining in the cargo tank and its associated piping into a calibrated container for measurement. Water residues shall be collected, inter alia, from the following points: . 1 the cargo tank suction and its vicinity; .2 any entrapped areas on the cargo tank bottom; .3 the low point drain of the cargo pump; and .4 all low point drains of piping associated with the cargo tank up to the manifold valve. 3.2.5 The total water volumes collected above determine the stripping quantity for the cargo tank. 3.2.6 Where a group of tanks is served by a common pump or piping, the water test residues associated with the common system(s) may be apportioned equally among the tanks provided that the following operational restriction is included in the ship's approved Manual: "For sequential unloading of tanks in this group, the pump or piping is not to be washed until all tanks in the group have been unloaded."

not less than 100 kPa at the cargo tank's unloading manifold. A For ships built before 1 July 1994 A prewash procedure is required in order to meet certain Annex II requirements. This appendix explains how these prewash procedures shall be performed. Prewash procedures for non-Solidifying Substances 1 Tanks shall be washed by means of a rotary water jet, operated at sufficiently high water pressure. In the case of Category X substances cleaning machines shall be operated in such locations that all tank surfaces are washed. In the case of Category Y substances only one location need be used. 2 During washing the amount of water in the tank shall be minimized by continuously pumping out slops and promoting flow to the suction point (positive list and trim). If this condition cannot be met the washing procedure shall be repeated three times, with thorough stripping of the tank between washings. 20°C shall be washed with hot water (temperature at least 60°C), unless the properties of such substances make the washing less effective. 4 The number of cycles of the cleaning machine used shall not be less than that specified in table 6-1. A cleaning machine cycle is defined as the period between two consecutive identical orientations of the tank cleaning machine (rotation through 360°). 5 After washing, the tank cleaning machine(s) shall be kept operating long enough to flush the pipeline, pump and filter, and discharge to shore reception facilities shall be continued until the tank is empty. Prewash procedures for Solidifying Substances 1 Tanks shall be washed as soon as possible after unloading. If possible tanks shall be heated prior to washing. 2 Residues in hatches and manholes shall preferably be removed prior to the prewash. 3 Tanks shall be washed by means of a rotary water jet operated at sufficiently high water pressure and in locations to ensure that all tank surfaces are washed. 4 During washing the amount of water in the tank shall be minimized by pumping out slops continuously and promoting flow to the suction point (positive list and trim). If properties of such substances make the washing less effective. 6 The number of cycles of the cleaning machine used shall not be less than that specified in table 6-1. A cleaning machine cycle is defined as the period between two consecutive identical orientations of the machine (rotation through 360°). 7 After washing, the cleaning machine(s) shall be kept operating long enough to flush the pipeline, pump and filter, and discharge to shore reception facilities shall be continues until the tank is empty. Table 6-1 ~ Number of cleaning machine cycles to be used in each location Category of substance Number of cleaning machine cycles Non-Solidifying Substances Solidifying Substances Category X 1 2 Category Y 1/2 1 B For ships built on or after 1 July 1994 and recommendatory for ships built before1 July 1994 A prewash procedure is required in order to meet certain Annex II requirements. This appendix explains how these prewash procedures shall be performed and how the minimum volumes of washing media to be used shall be determined. Smaller volumes of washing media may be used based on actual verification testing to the satisfaction of the Administration. Where reduced volumes are approved an entry to that effect must be recorded in the Manual. If a medium other than water is used for the prewash, the provisions regulation 13.5.1 apply. Prewash procedures for non-Solidifying Substances without recycling 1 Tanks shall be washed by means of a rotary jet(s), operated at sufficiently high water pressure. In the case of Category X substances cleaning machines shall be operated in such locations that all tank surfaces are washed. In the case of Category Y substances only one location need be used. 2 During washing the amount of liquid in the tank shall be minimized by continuously pumping out slops and promoting flow to the suction point. If this condition cannot be met, the washing procedure shall be repeated three times, with ΕΦΗΜΕΡΙΣ ΤΗΣ ΚΥΒΕΡΝΗΣΕΩΣ (ΤΕΥΧΟΣ ΠΡΩΤΟ) 255

20°C shall be washed with hot water (temperature at least 60°C), unless the properties of such substances make the washing less effective. 4 The quantities of wash water used shall not be less than those specified in paragraph 20 or determined according to paragraph 21. 5 After prewashing the tanks and lines shall be thoroughly stripped. Prewash procedures for Solidifying Substances without recycling 6 Tanks shall be washed as soon as possible after unloading. If possible, tanks should be heated prior to washing. 7 Residues in hatches and manholes should preferably be removed prior to the prewash. 8 Tanks shall be washed by means of a rotary jet(s) operated at sufficiently high water pressure and in locations to ensure that all tank surfaces are washed. 9 During washing the amount of liquid in the tank shall be minimized by pumping out slops continuously and promoting flow to the suction point. If this condition cannot be met, the washing procedure shall be repeated three times with thorough stripping of the tank between washings. 10 Tanks shall be washed with hot water (temperature at least 60°C), unless the properties of such substances make the washing less effective. 11 The quantities of wash water used shall not be less than those specified in paragraph 20 or determined according to paragraph 21. 12 After prewashing the tanks and lines shall be thoroughly stripped. Prewash procedures with recycling of washing medium 13 Washing with a recycled washing medium may be adopted for the purpose of washing more than one cargo tank. In determining the quantity, due regard must be given to the expected amount of residues in the tanks and the properties of the washing medium and whether any initial rinse or flushing is employed. Unless sufficient data are provided, the calculated end concentration of cargo residues in the washing medium shall not exceed 5% based on nominal stripping quantities. 14 The recycled washing medium shall only be used for washing tanks having contained the same or similar substance. 16 All tank surfaces shall be washed by means of a rotary jet(s) operated at sufficiently high pressure. The recycling of the washing medium may either be within the tank to be washed or via another tank, e.g. a slop tank. 17 The washing shall be continued until the accumulated throughput is not less than that corresponding to the relevant quantities given in paragraph 20 or determined according to paragraph 21. 18 Solidifying Substances and substances with viscosity equal to or greater than 50 mPa.s at 20°C shall be washed with hot water (temperature at least 60°C) when water is used as the washing medium, unless the properties of such substances make the washing less effective. 19 After completing the tank washing with recycling to the extent specified in paragraph 17, the washing medium shall be discharged and the tank thoroughly stripped. Thereafter, the tank shall be subjected to a rinse, using clean washing medium, with continuous drainage and discharged to a reception facility. The rinse shall as a minimum cover the tank bottom and be sufficient to flush the pipelines, pump and filter. Minimum quantity of water to be used in a prewash 20 The minimum quantity of water to be used in a prewash is determined by the residual quantity of noxious liquid substance in the tank, the tank size, the cargo properties, the permitted concentration in any subsequent wash water effluent, and the area of operation. The minimum quantity is given by the following formula: Q=k(15r0 . 8 + 5r0.7 x V/1000) where Q = the required minimum quantity in m3 r = the residual quantity per tank in m3 . The value of r shall be the value demonstrated in the actual stripping efficiency test, but shall not be taken lower than 0.100 m3 for a tank volume of 500 m3 and above and 0.040 m3 for a tank volume of 100 m3 and below. For tank sizes between 100 m3 and 500 m3 the minimum value of r allowed to be used in the calculations is obtained by linear interpolation. For Category X substances the value of r shall either be determined based on stripping tests according to the Manual, observing the lower limits as given above, or be taken to be 0.9 m3 .

Category X, non-Solidifying, Low-Viscosity Substance, k = 1.2 Category X, Solidifying or High-Viscosity Substance, k = 2.4 Category Y, non-Solidifying, Low-Viscosity Substance k = 0.5 Category Y, Solidifying or High-Viscosity Substance k = 1.0 The table below is calculated using the formula with a k factor of 1 and may be used as an easy reference.

The prewash volume so verified shall be adjusted for other prewash conditions by application of the factor k as defined in paragraph 20. APPENDIX 7 VENTILATION PROCEDURES 1 Cargo residues of substances with a vapour pressure greater than 5 KPa at 20°C may be removed from a cargo tank by ventilation. 2 Before residues of Noxious Liquid Substances are ventilated from a tank the safety hazards relating to cargo flammability and toxicity shall be considered. With regard to safety aspects, the operational requirements for openings in cargo tanks in SOLAS 74, as amended, the International Bulk Chemical Code, the Bulk Chemical

3 Port authorities may also have regulations on cargo tank ventilation. 4 The procedures for ventilation of cargo residues from a tank are as follows: . 1 the pipelines shall be drained and further cleared of liquid by means of ventilation equipment; .2 the list and trim shall be adjusted to the minimum levels possible so that evaporation of residues in the tank is enhanced; .3 ventilation equipment producing an airjet which can reach the tank bottom shall be used. Figure 7-1 could be used to evaluate the adequacy of ventilation equipment used for ventilating a tank of a given depth; .4 ventilation equipment shall be placed in the tank opening closest to the tank sump or suction point; .5 ventilation equipment shall, when practicable, be positioned so that the airjet is directed at the tank sump or suction point and impingement of the airjet on tank structural members is to be avoided as much as possible; and .6 ventilation shall continue until no visible remains of liquid can be observed in the tank. This shall be verified by a visual examination or an equivalent method.
