Category and classification of harmful, liquid substances and other substances
§ 3. By using the provisions of this notice, liquid substances are divided into four categories:
1) Category Category X: harmful, liquid substances, which, if they were exhausted in the sea by tank cleaning or by the exhaustion of ballast, would raise great danger either for the human resources or human health of the garden and therefore justify a ban on discharge in the sea.
2) Category Category Y: harmful, liquid substances, which, if they were exhausted in the sea by tank cleaning or by the exhausting of ballast, would raise either for the human resources or human health or would harm the garden’s recreational values or be to the re-use of the sea and therefore justify a limitation in the method and the amount of exhaustion in the sea.
3) 3) Category Z: harmful, liquid substances, which, if they were exhausted in the sea by tank cleaning or at the exhaustion of ballast, would raise a less danger either to the human resources or human health and therefore justify some minor restrictions on the method and quantity of exhaustion in the sea.
4) Other substances: substances listed as OS (Other Substances) in the column of pollution categories in Chapter 18 of the IBC code, which is assessed to fall outside category X, Y or Z, because they are not currently considered a risk of the marine resources, the human health, the garden’s recreational values or to be for other legal use of the sea, if they were exhausted in the sea during tank cleaning or exhausting of ballast.
§ 4. A liquid substance that is not covered by the IBC code and later additions to this must be classified by the City and Landscape Authority. The City and Landscape Authority shall, together with the governments of the Member States concerned to MARPOL, which are affected by the intended transport, conduct and agree on a temporary assessment of the intended transport on the basis of the guidelines laid down in Annex 1.

Annex 2
OILITY
1. Loaders of substances with a steam pressure of more than 5 KPa at 20°C can be removed from a load tank using ventilation.
2. Before residues of harmful, liquid substances are exhausted from a tank, the safety risks must be taken into account the load flammability and toxicity. As regards the safety conditions, you should take into account the operating requirements for openings in load tanks in SOLAS 74, with later changes, in accordance with the Danish Maritime Authority B, Technical regulatory for ships building and equipment etc., Chapter II-1; Construction - building, division and stability, machinery and electrical installations, International Bulk Chemical Code, Bulk Chemical Code, Bulk Chemical Code Code as well as ventilation procedures in Tanker Safety Guide (Chemicals) from the International Ship Chamber.
3. The sea authorities may also have provisions for the extraction of cargo tanks.
4. The procedures for the extraction of load residues from thought are as follows:
a. Pipe cords must be emptied and further cleaned for liquid using extraction equipment.
b. Blasting and trimming must be adjusted to the minimum possible levels to promote the evaporation of residues in the tank.
c. The ventilation equipment should be used, which forms an air beam that can reach the bottom of the tank. Figure 7-1 can be used to assess the adequateness of ventilation equipment used to exhaust a tank with a given depth.
d. The extraction equipment must be placed in the tank opening that is closest to the tank compartment or the extraction point.
e. The extraction equipment should be used if it is practical, placed so that the air beam is directed against the tank or extraction site, and it must be avoided that the air beam hits parts of the tank.
f. The discharge must continue until there are no visible residues of liquid left in the tank. This must be confirmed by the objection or in similar manner.

FORVASKPROCEDURE
A A A For ships built before 1 July 1994
A pre-wash procedure is required to meet Section 10(4)(b) of Section 11(3) and Section 12(3). This Annex explains how these pre-wash procedures should be carried out.
Disaster procedures for non-drying substances
1. Tanks must be washed using a rotating water jet at an adequate high water pressure. When there are substances from category X, the cleaning machines must be placed in positions ensuring that all the surfaces of the tank are washed. When there are substances from category Y, it is sufficient to be placed in a single position.
2. During cleaning, the amount of water in the tank is minimized by constantly pumping the wash water and ensure that it flows to the extraction site (positive penetration and trim). If these terms cannot be met, the washing procedure must be repeated three times with thorough emptying of the tank between each wash.
3. Substances with a viscosity of or greater than 50 mPa.s at 20°C must be washed by with hot water (temperature at least 60°C), unless the properties of the substances mean that the drain is less effective.
4. The cleaning machine used must, as minimum, run it in Table 6-1 specified number of cycles. A cycle for a cleaning machine is defined as the period between two on each other, identical orientations of the tank cleaning machine (360 degrees rotation).
5. After cleaning, the tank cleaning machine/s must not be interrupted before pipeline, pump and filter is rinsed through, and the discharge to receive facilities on land should be continued until the tank is empty.
Wash procedures for solid substances
6. The tanks should be washed as quickly as possible after unloading. If possible, the tanks must be heated before they are washed.
7. It is preferable if residues in hatches and manholes are removed before the prewash.
8. Tanks must be washed using a rotary water jet at an adequate high water pressure from cleaning machines placed in positions that ensure that all the surface of the tank is washed.
9. During cleaning, the amount of water in the tank is minimized by constantly pumping the wash water and ensure that it flows to the extraction site (positive penetration and trim). If these terms cannot be met, the washing procedure must be repeated three times with thorough emptying of the tank between each wash.
10. The tanks must be washed with hot water (temperature at least 60 °C), unless the properties of the substances mean that the drain is less effective.
11. The cleaning machine used must, as minimum, run it in Table 6-1 specified number of cycles. A cycle for a cleaning machine is defined as the period between two in each other, identical orientations of the machine (360 degrees rotation).
12. After cleaning, the tank cleaning machine/s must not be interrupted before pipeline, pump and filter is rinsed through, and the discharge to receive facilities on land should be continued until the tank is empty.

A pre-wash procedure is required to meet Section 10(4)(b) of Section 11(3) and Section 12(3). This Annex explains how these pre-wash procedures must be performed and how to determine the minimum amount of the detergent to be used. There may be less amounts of detergent if a test is carried out in particular that the result is satisfactory to the Danish Maritime Authority or other MARPOL Convention countries. If the use of reduced amounts is approved, a note must be made.
If another remedy is used than water to the sink, the provision of Section 16(1) applies.
Rewash procedures for non-drying substances without recycling
1. Tanks must be washed using (a) rotating beam(s) by an adequate high water pressure. When there are substances from category X, the cleaning machines must be placed in positions ensuring that all the surfaces of the tank are washed. When there are substances from category Y, it is sufficient that a single position is used.
2. During cleaning, the amount of liquid in the tank is minimized by constantly pumping the wash water and make sure it flows to the extraction site. If these terms cannot be met, the washing procedure must be repeated three times with thorough emptying of the tank between each wash.
3. Substances with a viscosity of or greater than 50 mPa.s at 20°C must be washed by with hot water (temperature at least 60°C), unless the properties of the substances mean that the drain is less effective.
4. The amount of water used shall not be less than the amounts specified in Section 20 or determined under Section 21.
5. After prewashing, tanks and pipelines must be thoroughly emptied
Wash procedures for solid substances without recycling
6. The tanks should be washed as quickly as possible after unloading. If possible, the tanks must be heated before they are washed.
7. It is preferable if residues in hatches and manholes are removed before the prewash.
8. Tanks must be washed using (a) rotating beam(s) by an adequate high water pressure from positions ensuring that all the surface of the tank is washed.
9. During cleaning, the amount of liquid in the tank is minimized by constantly pumping the wash water and make sure it flows to the extraction site. If these terms cannot be met, the washing procedure must be repeated three times with thorough emptying of the tank between each wash.
10. The tanks must be washed with hot water (temperature at least 60 °C), unless the properties of the substances mean that the drain is less effective.
11. The amount of water used shall not be less than the amounts specified in Section 20 or determined under Section 21.
12. After prewashing, tanks and pipelines must be carefully emptied.
Cleaning procedures with the recycling of the detergent
13. Cleaning with recycled detergent can be used for cleaning more than one load tank. When the quantity is to be determined, appropriate consideration for the expected amount of residues in the tanks, the characteristics of the detergent, and whether in advance, rinse or flushing. Unless sufficient data is presented, the final concentration of load residues must not exceed 5% based on nominal empty amounts.
14. The recycled detergent must only be used for cleaning tanks that have contained the same or a similar substance.
15. A number of detergents that are sufficient to allow continued to wash, to the tank or the tanks to be washed.
16. All tank surfaces must be washed using (a) rotating beam(s) at an adequate high pressure. The recycling of the detergent can either be done in the tank to be washed or done via another tank, such as a slop tank.
17. The withdrawal must continue until the accumulated amount is not less than what corresponds to the relevant quantities specified in Section 20 or determined under Section 21.
18. Sdrying substances and substances with a viscosity of or greater than 50 mPa.s at 20°C must be washed with hot water (temperature at least 60°C) if water is used, unless the properties of substances mean that the defrosting becomes less effective.
19. When the cleaning of the tank is carried out with recycling to the extent specified in section 17, the detergent must be emptied and the tank is carefully emptied. Then the tank must be rinsed with pure detergent, which is continuously emptied and in a receiving facility. The rinse should include the bottom of the tank and be sufficient to rinse pipelines, pump and filter through.
Minimum allowed amount of water for use by prewash
20. The minimum amount of water for use by prewash depends on the amount of harmful liquid substances in the tank, the size of the tank, the load characteristics, the allowed concentration in wastewater from the drain and the application area. The minimum quantity is found using the following formula:
Q=k(15r0.8 + 5r0.7 x V/1000)
| ||
where
| ||
Q Q
| = the required minimum quantity in m3 | |
r
| = residual amount per tank in m3. The value for r must be the value shown by the actual test of emptying efficiency, but must not be lower than 0,100 m3 for a capacity of 500 m3 and over 0.01 m3 for a tank range of 100 m3 and below. For tank sizes of between 100 m3 and 500 m3 The minimum allowed value for the r to be used by the bill, by linear interpolation.
| |
For substances from category X is the value of r either by emptying test according to the Manual in compliance with the above mentioned minimum limits, or it is put to 0.9 m3.
V

| tank's range in m3 | |
k
| = =
| a factor with the following values:
| |
Non-drying fabric from category X with low viscosity
| k = 1.2
| ||
Great fabric or fabric with high viscosity from category X
| k = 2.4
| ||
Non-drying fabric from category Y with low viscosity
| k = 0.5
| ||
Great fabric or fabric with high viscosity from category Y
| k = 1.0

The table below is calculated using the formula and with a k-factor of 1. The table can be used for quick post.

21. It is permitted to carry out verification testing provided that the Danish Maritime Authority or other MARPOL Convention countries find this satisfactory, for the purpose of the authorisation of pre-washing volumes which are lower than those specified in Section 20, to demonstrate that the requirements of the notice are met, since the substances the ship is approved to carry out. Thus, the pre-determined pre-washing amount must be adapted to other conditions by the prewash using it in Section 20 defined factor.
1) The decision contains provisions implementing parts of Directive 2005/35/EC of the European Parliament and of the Council of 7 September 2005 on pollution from ships and on the introduction of sanctions for infringements (EC-Tidende 2005 No L 255, page 11).
