(10)This rule uses a simplified probabilistic approach where a summation is carried out over the contributions to the mean outflow from each cargo tank and for certain designs, such as those characterised by the occurrence of steps/recesses in bulkheads/decks and for sloping bulkheads and/or a pronounced hull curVature, more rigorous calculations may be appropriate and in such cases, one of the following calculation procedures may be applied, namely:-

(a)the probabilities referred to in sub-rules (8) and (9) above maybe calculated with more precision through application of hypothetical sub-compartments;

(b)the probabilities referred to in sub-rules (8) and (9) above may be calculated through direct application of the probability density functions contained in,the Guidelines referred to in sub-rule (5) of rule 19;

(c)the oil outflow performance may be evaluated in accordance with the method described in the Guidelines referred to in sub-rule (5) of rule 19.

(11)The following provisions regarding piping arrangements shall apply-

(b)credit for reducing oil outflow through the use of an emergency rapid cargo transfer system or other system arranged to mitigate oil outflow in the event of an accident may be taken into account only after the effectiveness and safety aspects of the system are approved by the Central Government and the Organization.

24. Damage Assumptions.

(1)For the purpose of calculating hypothetical oil outflow from oil tankers in accordance with rules 25 and 26, three dimensions of the extent of damage of a parallelepiped on the side and bottom of the ship are assumed as given below and in the case of bottom damages, two conditions are set forth to be applied individually to the stated portions of the oil tanker:

(a)Side damage:

(i)	Longitudinal extent (Ic) :	1/3L2/3or 14.5m, whichever is less
(ii)	Transverse extent (Tc) (inboard from the ship'sside at right is less angles to the centerline at the levelcorresponding to the assigned summer freeboard):	B/5 or 11.5 m, whichever is less
(iii)	Vertical extent (Vc):	From the baseline upwards without limit

(b)Bottom damage -

	For 0.3 L from the forward perpendicular of the ship	Any other part of the ship
(i) Longitudinal extent (ls):	L/10	L/10 or 5m whichever is less
(ii) Transverse extent (ts)	B/6 or 10 m, whichever is less than not less than 5m	5m
(iii) Vertical extent from the baseline (vs):	B/15 or 6 m, whichever is less

(2)The symbols given in this rule when appear elsewhere in this chapter, they shall have the meaning as defined in this rule -

25. Hypothetical Outflow of Oil.

(1)The hypothetical outflow of oil in the case of side damage (Oc) and bottom damage (Os) shall be calculated by the following formulae with respect to compartments breached by damage to all conceivable locations along the length of the ship to the extent as defined in rule 24.

(a)For side damages:

Oc = ∑Wi + ∑KiCi (I)

(b)For bottom damages:

Os =1/3(∑ZiWi + ∑ZiCi) (I)where:

Wi=	Volume of a wing tank, in cubic metres, assumedto be breached by the damage as specified in rule 24 and wi for asegregated ballast tank may be taken equal to zero.
Ci=	volume of a centre tank, in cubic metres,assumed to be breached by the damage as specified in rule 24; Cifor a segregated ballast tank may be taken equal to zero.
Ki=	1-bi/tcWhen bi is equal to or greater thantc, Kishall be taken equal to zero.
Zi=	1-hi/VsWhen hi is equal to or greater thanVs, Zishall be taken equal to zero.
bi=	Width of wing tank under consideration,. inmetres, measured inboard from the ship's side at right angles tothe centerline at the level corresponding to the assigned summerfreeboard.
hi=	minium depth of the double bottom underconsideration, in metres; where no double bottom is fitted, hishall be taken equal to zero.

(IA)The symbols given in this paragraph when appear elsewhere in this chapter, they shall have the meaning as defined in this rule.

(2)If a void space or segregated ballast tank of a length less than lcIc, as defined in rule 24, is located between wing oil tanks, Oc in formula (I) may be calculated on the basis of volume wi being the actual volume of one such tank (where they are of equal capacity) or the smaller of the two tanks (if they differ in capacity) adjacent to such space, multiplied by Si as defined below and taking for all other wing tanks involved in such collision the value of the actual full volume.Si = 1 - li/lcwhere li = length, In metres, of void space or segregated ballast tank under consideration.

(3)

(a)Credit shall only be given in respect of double bottom tanks, which are either empty or carrying clean water when cargo is carried in the tanks above.

(b)Where the double bottom does not extend for the full length and width of the tank involved, the double bottom is considered non-existent and the volume of the tanks above the area of the bottom damage shall be included in formula (II) even if the tank is not considered breached because of the installation of such a partial double bottom.

(c)Suction wells may be neglected in the determination of the value hi provided such wells are not excessive in area and extend below the tank for a minimum distance and in no case more than half the height of the double bottom and if the depth of such a well exceeds half the height of the double bottom, hi shall be taken equal to the double bottom height minus the well height.

(d)Piping serving such wells if installed within the double bottom shall be fitted with valves or other closing arrangements located at the point of connection to the tank served to prevent oil outflow in the event of damage to the piping. Such piping shall be installed as high from the bottom shell as possible and these valves shall be kept closed at sea at any time when the tank contains oil cargo, except that they maybe opened only for cargo transfer needed for the purpose of trimming of the ship.

(4)In the case where bottom damage simultaneously involves four centre tanks, the value of Os may be calculated according to the formula:Os = ¼(∑Zi + ∑ZiCi) (III)

(5)The Central Government may credit as reducing oil outflow in case of bottom damage, an installed cargo transfer system having an emergency high suction in each cargo oil tank, capable of transferring from a breached tank or tanks to segregated ballast tanks or to available cargo tankage if it can be assured that such tanks will have sufficient ullage:Provided that the credit for such a system would be governed by ability to transfer in two hours of operation oil equal to one half of the largest of the breached tanks involved and by availability of equipment receiving capacity in ballast or cargo tanks:Provided further that such credit shall be confined to permitting calculation of Os according to formula (III):Provided also that the pipes for such suctions shall be installed at least at a height not less than the vertical extent of the bottom damage Vs:Provided also that the Central Government shall supply the Organization with the information concerning the arrangements accepted by 'it, for circulation to other State Parties.

The Second Schedule[See Clause (50) of rule 1A]Specifications for the design, installation and operation of a part flow system for control of overboard discharges

1. Purpose

1.1The purpose of these specifications is to provide specific design criteria and installation and operational requirements for the part flow system referred to in clause (e) sub-rule (6) of rule 31.

2. Application

2.1Oil tankers delivered on or before 31 December 1979, as defined in sub-rule (54) of rule 2, may, in accordance with clause (e) sub rule (6) of rule 31., discharge dirty ballast water and oil-contaminated water from cargo tank area,s below the waterline, provided that a part of the flow is led through permanent piping to a readily accessible location on the upper deck or above where it may be visually observed during the discharge' operation and provided that the arrangements comply with the requirements established by the Director General shall at least contain all the provisions of these specifications.

2.2The part flow concept is based on the principle that the observation of a representative part flow of the overboard effluent is equivalent to observing the entire effluent stream. These specifications provide the details of the design, installation and operation of a part flow system.

3. General provisions

3.1The part flow system shall be so fitted that it can effectively provide a representative sample of the overboard effluent for visual display under all normal operating conditions.

3.2The part flow system is in many respects similar to the sampling system for an oil discharge monitoring and control system but shall have pumping and piping arrangements separate from such a system, or combined equivalent arrangements acceptable to the Director General.

3.3The display of the part flow shall be arranged in a sheltered and readily accessible location on the upper deck or above, approved by the Director General (e.g. the entrance to the pump-room). Regard should be given to effective communication between the location of the part flow display and the discharge control position.

3.4Samples shall be taken from relevant sections of the overboard discharge piping and be passed to the display arrangement through a permanent piping system.

3.5The part flow system shall include the following components:

1. sampling probes;

2. sample water piping system

3. sample feed pump(s);

4. display arrangements;

5. sample discharge arrangements subject to the diameter of the sample piping

6. flushing arrangement.

3.6The part flow system shall comply with the applicable safety requirements.

4. System arrangement

4.1Sampling points

4.1.1Sampling point location:

1. Sampling points shall be so located that relevant samples can be obtained of the effluent being discharged through outlets below the water line which are used for operational discharges.

2. Sampling points shall as far as practicable be located in pipe sections where a turbulent flow is nprrnall1y encountered.

3. Sampling points shall as far as far as practicable be arranged in accessible locations vertical sections of the discharge piping

4.1.2sampling probes

1. Sampling probes shall be arranged to protrude into the pipe a distance about on fourth of the pipe diameter.

2. Sampling probes shall be arranged for easy withdrawal for cleaning

3. The part flow system shall have a stop valve fitted adjacent to each probe, except that where the probe is mounted in a cargo line two stop valves shall be fitted in series, in the sample line.

4. Sampling probes should be of corrosion-resistant and oil-resistant material of adequate strength, properly jointed and supported.

5. Sampling probes shall have shape that is not prone to becoming clogged by particle contaminants and should not generate high hydrodynamic pressures at the sampling probe tip. Figure is an example of one suitable shape of a sampling probe.

6. Sampling probes shall have the same nominal bore as the sample piping

4.2Sample piping

1. The sample piping shall be arranged as straight as possible between the sampling points and he display arrangement. Sharp bends and pockets where settled oil or sediment may accumulate should be avoided.

2. The sample piping shall be so arranged that sample water is conveyed to the display arrangement within 20 s. The flow velocity in the piping should not be less than 2 m/s.

3. The diameter of the piping shall not be less than 40 mm if no fixed flushing arrangement is provided and shall not be less than 25mm if a pressurized flushing arrangement as detailed in paragraph 4.4 is installed.

4. The sample piping should be of corrosion-resistant and oil-resistant material, of adequate strength, properly jointed and supported.

5. Where several sampling points are installed, the piping shall be connected to a valve chest at the suction side of the sample feed pump.

4.3Sample feed pump

1. The sample feed pump capacity shall be suitable to allow the flow rate of the sample water to comply with 4.2.2.

4.4Flushing arrangement

1. If the diameter of sample piping is less than 40 mm, a fixed connection from a pressurized sea or fresh water piping system shall be' installed for flushing of the sample piping system.

4.5Display arrangement.

1. The display arrangement shall consist of a display chamber provided with a sight glass. The chamber should be of a size that will allow a free fall stream of the sample water to be clearly visible over a length to at least 200 nim. The Administration may approve equivalent arrangements.

2. The display arrangement shall incorporate valves and piping in order to allow part of the sample flow to bypass the display chamber to obtain a laminar flow for display in the chamber.

3. The display arrangement shall be designed to be easily opened and cleaned.

4. The interior of the display chamber shall be white except for the background wall which shall be so coloured as to facilities the observation of any change in the quality of the sample water.

5. The lower part of the display chamber shall be shaped like a funnel for collection of the sample water.

6. A test cock for taking a grab sample shall be provided in order that a sample of the water can be examined independent of that in the display chamber.

7. The display arrangement shall be adequately lighted to facilitate visual observation of the sample water.

4.6Sample discharge arrangement

1. The sample water leaving the display chamber shall be routed to the sea,or to a slop tank through fixed piping of adequate diameter.

5. Operation

5.1When a discharge of dirty ballast water or other oil-contaminated water from the cargo tank area is taking place through an outlet below the waterline, the part flow system shall provide sample water from the relevant discharge outlet at all times.

5.2The sample water should be observed particularly during those phases of the discharge operation when the greatest possibility of oil contamination occurs. The discharge shall be stopped whenever any traces of oil are visible in the flow and when the oil content meter reading indicates that the oil content exceeds permissible limits.

5.3On those systems that are fitted with flushing arrangements, the sample piping should be flushed' after contamination has been observed and, additionally, it is recommended that the sample piping be flushed after each period of usage.

5.4The ship's cargo and ballast handling manuals and, where applicable, those manuals required for crude oil washing systems or dedicated clean ballast tanks operation shall clearly describe the use of the part flow system in conjunction with the ballast discharge and the slop tank decanting procedures.List of Resolutions of the Organisation
