.1 "Load line draught (dS)" is the vertical distance, in metres, from the moulded baseline at mid-length to the waterline corresponding to the summer freeboard to be assigned to the ship. Calculations pertaining to this regulation should be based on draught dS, notwithstanding assigned draughts that may exceed dS, such as the tropical loadline.
.2 "Waterline (dB)" is the vertical distance, in metres, from the moulded baseline at mid-length to the waterline corresponding to 30% of the depth DS.

3 To provide adequate protection against oil pollution in the event of collision or stranding the following shall be complied with:
.1 for oil tankers of 5,000 tonnes deadweight (DWT) and above, the mean oil outflow parameter shall be as follows:
OM = 0.015
for C = 200,000 m3
OM = 0.012 + (0.003/200,000) (400,000-C)
for 200,000 m3 < C < 400,000 m3
OM = 0.012
for C = 400,000 m3
for combination carriers between 5,000 tonnes deadweight (DWT) and 200,000 m3 capacity, the mean oil outflow parameter may be applied, provided calculations are submitted to the satisfaction of the Administration, demonstrating that after accounting for its increased structural strength, the combination carrier has at least equivalent oil out flow performance to a standard double hull tanker of the same size having a OM < = 0.015.

4 The following general assumptions shall apply when calculating the mean oil outflow parameter:
.1 The cargo block length extends between the forward and aft extremities of all tanks arranged for the carriage of cargo oil, including slop tanks.
.2 Where this regulation refers to cargo tanks, it shall be understood to include all
cargo tanks, slop tanks and fuel tanks located within the cargo block length.
.3 The ship shall be assumed loaded to the load line draught dS without trim or heel.
.4 All cargo oil tanks shall be assumed loaded to 98% of their volumetric capacity. The nominal density of the cargo oil ( r n) shall be calculated as follows:
r n = 1000 (DWT)/C (kg/m3)
.5 For the purposes of these outflow calculations, the permeability of each space within the cargo block, including cargo tanks, ballast tanks and other non-oil spaces shall be taken as 0.99, unless proven otherwise.
.6 Suction wells may be neglected in the determination of tank location provided that such wells are as small as practicable and the distance between the well bottom and bottom shell plating is not less than 0.5h, where h is the height as defined in regulation 19.3.2.
5 The following assumptions shall be used when combining the oil outflow parameters:
.1 The mean oil outflow shall be calculated independently for side damage and for bottom damage and then combined into the non-dimensional oil outflow parameter OM, as follows:
OM = (0.4 OMS + 0.6 OMB ) / C
where:
OMS = mean outflow for side damage, in m3; and OMB = mean outflow for bottom damage, in m3.
.2 For bottom damage, independent calculations for mean outflow shall be done for 0 m and minus 2.5 m tide conditions, and then combined as follows:
OMB = 0.7 OMB(0) + 0.3 OMB(2.5)
where:
OMB(0) = mean outflow for 0 m tide condition; and
OMB(2.5) = mean outflow for minus 2.5 m tide condition, in m3.
6 The mean outflow for side damage OMS shall be calculated as follows:
[Editor's Note: Equation has been removed, refer to page 40 of original document]
where:
represents each cargo tank under consideration;
total number of cargo tanks;
the probability of penetrating cargo tank i from side damage, calculated in accordance with paragraph 8.1 of this regulation;
OS(i) = the outflow, in m3, from side damage to cargo tank i, which is assumed equal to the total volume in cargo tank i at 98% filling, unless it is proven through the application of the Guidelines referred to in regulation 19.5 that any significant cargo volume will be retained; and
0.77 for ships having two longitudinal bulkheads inside the cargo tanks, provided these bulkheads are continuous over the cargo block and Ps(i) is developed in accordance with this regulation. C3 equals 1.0 for all other ships or when Ps(i) is developed in accordance with paragraph 10 of this regulation.
7 The mean outflow for bottom damage shall be calculated for each tidal condition as follows:
[Editor's Note: Equation has been removed, refer to page 41 of original document]
where:
I = represents each cargo tank under consideration;
N = the total number of cargo tanks;
the probability of penetrating cargo tank i from bottom damage, calculated in accordance with, paragraph 9.1 of this regulation;
OB(i) = the outflow from cargo tank i, in m3, calculated in accordance with paragraph 7.3 of this regulation; and
CDB(i) = factor to account for oil capture as defined in paragraph 7.4 of this regulation
[Editor's Note: Equation has been removed, refer to page 41 of original document]
where:
i,n, PB(i) and CDB(i) = as defined in subparagraph .1 above;
OB(i) = the outflow from cargo tank i, in m³, after tidal change
.3 The oil outflow OB(i) for each cargo oil tank shall be calculated based on pressure balance principles, in accordance with the following assumptions:
.1 The ship shall be assumed stranded with zero trim and heel, with the stranded draught prior to tidal change equal to the load line draught ds.
.2 The cargo level after damage shall be calculated as follows:
hc = {(ds + tc - Zl) (r s) - (1000 p) / g }/r n
where:
hc = the height of the cargo oil above Zl, in metres;
tc = the tidal change, in m. Reductions in tide shall be expressed as negative values;
Zl = the height of the lowest point in the cargo tank above baseline, in m;
density of seawater, to be taken as 1,025 kg/m3;
if an inert gas system is fitted, the normal overpressure, in kPa, to be taken as not less than 5 kPa; if an inert gas system is not fitted, the overpressure may be taken as 0;
the acceleration of gravity, to be taken as 9.81 m/s2; and nominal density of cargo oil, calculated in accordance with paragraph 4.4 of this regulation.
.3 For cargo tanks bounded by the bottom shell, unless proven otherwise, oil outflow OB(i) shall be taken not less than 1% of the total volume of cargo oil loaded in cargo tank i, to account for initial exchange losses and dynamic effects due to current and waves.
.4 In the case of bottom damage, a portion from the outflow from a cargo tank may be captured by non-oil compartments. This effect is approximated by application of the factor CDB(i) for each tank, which shall be taken as follows:
CDB(i) = 0.6 for cargo tanks bounded from below by non-oil compartments;
CDB(i) = 1.0 for cargo tanks bounded by the bottom shell.
8 The probability PS of breaching a compartment from side damage shall be calculated as follows:
.1 PS = PSL PSV PST
where:

10 This regulation uses a simplified probabilistic approach where a summation is carried out over the contributions to the mean outflow from each cargo tank. For certain designs such as those characterized 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. In such cases one of the following calculation procedures may be applied:
.1 The probabilities referred to in 8 and 9 above may be calculated with more precision through application of hypothetical sub-compartments. [3]
.2 The probabilities referred to in 8 and 9 above may be calculated through direct application of the probability density functions contained in the Guidelines referred to in regulation 19.5.
.3 The oil outflow performance may be evaluated in accordance with the method described in the Guidelines referred to in regulation 19.5.
11 The following provisions regarding piping arrangements shall apply:
.1 Lines of piping that run through cargo tanks in a position less than 0.30Bs from the ship's side or less than 0.30Ds from the ship's bottom shall be fitted with valves or similar closing devices at the point at which they open into any cargo tank. These valves shall be kept closed at sea at any time when the tanks contain cargo oil, except that they may be opened only for cargo transfer needed for essential cargo operations.
.2 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 Organization. Submittal for approval shall be made in accordance with the provisions of the Guidelines referred to in regulation 19.5.
Regulation 24
Damage assumptions
1 For the purpose of calculating hypothetical oil outflow from oil tankers in accordance with regulations 25 and 26, three dimensions of the extent of damage of a parallelepiped on the side and bottom of the ship are assumed as follows. In the case of bottom damages two conditions are set forth to be applied individually to the stated portions of the oil tanker.
.1 Side damage:
1 Longitudinal extent(lc):
1/3 L 2/3 or 14.5 metres, whichever is less.
2 Transverse extent (tc) (inboard from the ship's side B/5 or 11.5 metres, at right angles to the centreline at the level whichever is less corresponding to the assigned summer freeboard):
3 Vertical extent (vc): From the base line upwards without limit
.2 Bottom damage:
For 0.3L from the Any other part of the forward perpendicular ship
of the ship
1 Longitudinal extent (ls): L/10
L/10 or 5 metres, whichever is less
2 Transverse extent (ts):
B/6 or 10 metres, 5 metres whichever is less but not ess than 5 metres
3 Vertical extent from the B/15 or 6 metres, base line (vs):
whichever is less
2 Wherever the symbols given in this regulation appear in this chapter, they have the meaning as defined in this regulation.
Regulation 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 regulation 24 of this Annex.
.1 For side damages:
.2 Oc = SWi + S KiCi
For bottom damages: [TAB] (I)
Os = 1/3 (S ZiWi + S ZiCi) [TAB] (II)
where: Wi = volume of a wing tank in cubic metres assumed to be breached by the damage as specified in regulation 24 of this Annex; Wi for a segregated 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 regulation 24 of this Annex; Ci for a segregated ballast tank may be taken equal to zero.
Ki = 1- bi/tc when bi is equal to or greater than tc, Ki shall be taken equal to zero.
Zi = 1- hi/vs, when hi is equal to or greater than vs, Zi shall be taken equal to zero.
bi = width of wing tank in metres under consideration measured inboard from the ship's side at right angles to the centreline at the level corresponding to the assigned summer freeboard.
hi = minimum depth of the double bottom in metres under consideration; where no double bottom is fitted hi shall be taken equal to zero.
Whenever symbols given in this paragraph appear in this chapter, they have the meaning as defined in this regulation.
2 If a void space or segregated ballast tank of a length less than lc as defined in regulation 24 of this Annex 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.
3 .1 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.
.2 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.
.3 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. 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.
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. These valves shall be kept closed at sea at any time when the tank contains oil cargo, except that they may be opened only for cargo transfer needed for the purpose of trimming of the ship.
4 In these case where bottom damage simultaneously involves four centre tanks, the value of Os may be calculated according to the formula:
Os = 1/4 (S ZiWi + S ZiCi) [TAB] (III)
5 An Administration 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. 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 equivalent receiving capacity in ballast or cargo tanks. The credit shall be confined to permitting calculation of Os according to formula (III). The pipes for such suctions shall be installed at least at a height not less than the vertical extent of the bottom damage vs. The Administration shall supply the Organization with the information concerning the arrangements accepted by it, for circulation to other Parties to the Convention.
6 This regulation does not apply to oil tankers delivered on or after 1 January 2010, as defined in regulation 1.28.8.
Regulation 26

2 Cargo tanks of oil tankers shall be of such size and arrangements that the hypothetical outflow Oc or Os calculated in accordance with the provisions of regulation 25 of this Annex anywhere in the length of the ship does not exceed 30,000 cubic metres or 400 3 DW , whichever is the greater, but subject to a maximum of 40,000 cubic metres.
3 The volume of any one wing cargo oil tank of an oil tanker shall not exceed 75 per cent of the limits of the hypothetical oil outflow referred to in paragraph 2 of this regulation. The volume of any one centre cargo oil tank shall not exceed 50,000 cubic metres. However, in segregated ballast oil tankers as defined in regulation 18 of this Annex, the permitted volume of a wing cargo oil tank situated between two segregated ballast tanks, each exceeding lc in length, may be increased to the maximum limit of hypothetical oil outflow provided that the width of the wing tanks exceeds tc.
4 The length of each cargo tank shall not exceed 10 m or one of the following values, whichever is the greater:

(0.25 B + 0.15) L
.4 bi is the minimum distance from the ship's side to the outer longitudinal bulkhead of the tank in question measured inboard at right angles to the centreline at the level corresponding to the assigned summer freeboard.
5 In order not to exceed the volume limits established by paragraphs 2, 3 and 4 of this regulation and irrespective of the accepted type of cargo transfer system installed, when such system interconnects two or more cargo tanks, valves or other similar closing devices shall be provided for separating the tanks from each other. These valves or devices shall be closed when the tanker is at sea.
6 Lines of piping which run through cargo tanks in a position less than tc from the ship's side or less than vc from the ship's bottom shall be fitted with valves or similar closing devices at the point at which they open into any cargo tank. These valves shall be kept closed at sea at any time when the tanks contain cargo oil, except that they may be opened only for cargo transfer needed for the purpose of trimming of the ship.
7 This regulation does not apply to oil tankers delivered on or after 1 January 2010, as defined in regulation 1.28.8.
Regulation 27
Intact stability
1 Every oil tanker of 5,000 tonnes deadweight and above delivered on or after 1 February 2002, as defined in regulation 1.28.7, shall comply with the intact stability criteria specified in paragraphs 1.1 and 1.2 of this regulation, as appropriate, for any operating draught under the worst possible conditions of cargo and ballast loading, consistent with good operational practice, including intermediate stages of liquid transfer operations. Under all conditions the ballast tanks shall be assumed slack.
.1 In port, the initial metacentric height GMo, corrected for the free surface measured at 0° heel, shall be not less than 0.15 m;
.2 At sea, the following criteria shall be applicable:
.1 the area under the righting lever curve (GZ curve) shall be not less than 0.055 m.rad up to ? = 30° angle of heel and not less than 0.09 m.rad up to ? = 40° or other angle of flooding ?f [4] if this angle is less than 40° Additionally, the area under the righting lever curve (GZ curve) between the angles of heel of 30° and 40° or between 30° and ?f, if this angle is less than 40°, shall be not less than 0.03 m.rad;

Regulation 28
Subdivision and damage stability
1 Every oil tanker delivered after 31 December 1979, as defined in regulation 1.28.2, of 150 gross tonnage and above, shall comply with the subdivision and damage stability criteria as specified in paragraph 3 of this regulation, after the assumed side or bottom damage as specified in paragraph 2 of this regulation, for any operating draught reflecting actual partial or full load conditions consistent with trim and strength of the ship as well as relative densities of the cargo. Such damage shall be applied to all conceivable locations along the length of the ship as follows:
.1 in tankers of more than 225 metres in length, anywhere in the ship's length;
.2 in tankers of more than 150 metres, but not exceeding 225 metres in length, anywhere in the ship's length except involving either after or forward bulkhead bounding the machinery space located aft. The machinery space shall be treated as a single floodable compartment; and
.3 in tankers not exceeding 150 metres in length, anywhere in the ship's length between adjacent transverse bulkheads with the exception of the machinery space. For tankers of 100 metres or less in length where all requirements of paragraph 3 of this regulation cannot be fulfilled without materially impairing the operational qualities of the ship, Administrations may allow relaxations from these requirements.
Ballast conditions where the tanker is not carrying oil in cargo tanks, excluding any oil residues, shall not be considered.
2 The following provisions regarding the extent and the character of the assumed damage shall apply:
[Editor's Note: Table removed, refer to page 53, 54, of original document]
.3 If any damage of a lesser extent than the maximum extent of damage specified in subparagraphs 2.1 and 2.2 of this paragraph would result in a more severe condition, such damage shall be considered.
.4 Where the damage involving transverse bulkheads is envisaged as specified in subparagraphs 1.1 and 1.2 of this regulation, transverse watertight bulkheads shall be spaced at least at a distance equal to the longitudinal extent of assumed damage specified in subparagraph 2.1 of this paragraph in order to be considered effective. Where transverse bulkhead are spaced at a lesser distance, one or more of these bulkheads within such extent of damage shall be assumed as non-existent for the purpose of determining flooded compartments.
.5 Where the damage between adjacent transverse watertight bulkheads is envisaged as specified in subparagraph 1.3 of this regulation, no main transverse bulkhead or a transverse bulkhead bounding side tanks or double bottom tanks shall be assumed damaged, unless:
.1 the spacing of the adjacent bulkheads is less than the longitudinal extent of
assumed damage specified in subparagraph 2.1 of this paragraph; or
.2 there is a step or recess in a transverse bulkhead of more than 3.05 metres in length, located within the extent of penetration of assumed damage. The step formed by the after peak bulkhead and after peak top shall not be regarded as a step for the purpose of this regulation.
.6 If pipes, ducts or tunnels are situated within the assumed extent of damage, arrangements shall be made so that progressive flooding cannot thereby extend to compartments other than those assumed to be floodable for each case of damage.
3 Oil tankers shall be regarded as complying with the damage stability criteria if the following requirements are met:
.1 The final waterline, taking into account sinkage, heel and trim, shall be below the lower edge of any opening through which progressive flooding may take place. Such openings shall include air-pipes and those which are closed by means of weathertight doors or hatch covers and may exclude those openings closed by means of watertight manhole covers and flush scuttles, small watertight cargo tank hatch covers which maintain the high integrity of the deck, remotely operated watertight sliding doors, and sidescuttles of the non-opening type.
.2 In the final stage of flooding, the angle of heel due to unsymmetrical flooding shall not exceed 25°, provided that this angle may be increased up to 30° if no deck edge immersion occurs.
.3 The stability in the final stage of flooding shall be investigated and may be regarded as sufficient if the righting lever curve has at least a range of 20° beyond the position of equilibrium in association with a maximum residual righting lever of at least 0.1 metre within the 20° range; the area under the curve within this range shall not be less than 0.0175 metre radians. Unprotected openings shall not be immersed within this range unless the space concerned is assumed to be flooded. Within this range, the immersion of any of the openings listed in subparagraph 3.1 of this paragraph and other openings capable of being closed watertight may be permitted.
.4 The Administration shall be satisfied that the stability is sufficient during intermediate stages of flooding.
.5 Equalization arrangements requiring mechanical aids such as valves or cross-levelling pipes, if fitted, shall not be considered for the purpose of reducing an angle of heel or attaining the minimum range of residual stability to meet the requirements of subparagraphs 3.1, 3.2 and 3.3 of this paragraph and sufficient residual stability shall be maintained during all stages where equalization is used. Spaces which are linked by ducts of a large cross-sectional area may be considered to be common.
4 The requirements of paragraph 1 of this regulation shall be confirmed by calculations which take into consideration the design characteristics of the ship, the arrangements, configuration and contents of the damaged compartments; and the distribution, relative densities and the free surface effect of liquids. The calculations shall be based on the following:
.1 Account shall be taken of any empty or partially filled tank, the relative density of cargoes carried, as well as any outflow of liquids from damaged compartments.
.2 The permeabilities assumed for spaces flooded as a result of damage shall be as follows:
[Editor's Note: following table has been reformatted, refer to page56 of original document]
Spaces [TAB] Permeabilities
Appropriated to stores [TAB] 0.60
Occupied by accommodation [TAB] 0.95
Occupied by machinery [TAB] 0.85
Voids [TAB] 0.95
Intended for consumable liquids [TAB] 0 to 0.95 [5]
Intended for other liquids [TAB] 0 to 0.95 [5]
.3 The buoyancy of any superstructure directly above the side damage shall be disregarded. The unflooded parts of superstructures beyond the extent of damage, however, may be taken into consideration provided that they are separated from the damaged space by watertight bulkheads and the requirements of subparagraph .1 of this regulation in respect of these intact spaces are complied with. Hinged watertight doors may be acceptable in watertight bulkheads in the superstructure.
.4 The free surface effect shall be calculated at an angle of heel of 5° for each individual compartment. The Administration may require or allow the free surface corrections to be calculated at an angle of heel greater than 5° for partially filled tanks.
.5 In calculating the effect of free surfaces of consumable liquids it shall be assumed that, for each type of liquid at least one transverse pair or a single centreline tank has a free surface and the tank or combination of tanks to be taken into account shall be those where the effect of free surface is the greatest.
5 The master of every oil tanker to which this regulation applies and the person in charge of a non-self-propelled oil tanker, to which this regulation applies shall be supplied in a approved form with:
.1 information relative to loading and distribution of cargo necessary to ensure compliance with the provisions of this regulation; and
.2 data on the ability of the ship to comply with damage stability criteria as determined by this regulation, including the effect of relaxations that may have been allowed under subparagraph 1.3 of this regulation.
6 For oil tankers of 20,000 tonnes deadweight and above delivered on or after 6 July 1996, as defined in regulation 1.28.6, the damage assumptions prescribed in paragraph 2.2 of this regulation shall be supplemented by the following assumed bottom raking damage:
.1 longitudinal extent:
.1 ships of 75,000 tonnes deadweight and above: 0.6L measured from the forward perpendicular;
.2 ships of less than 75,000 tonnes deadweight: 0.4L measured from the forward perpendicular;
.2 transverse extent: B/3 anywhere in the bottom;
.3 vertical extent: breach of the outer hull.
Regulation 29
Slop tanks
1 Subject to the provisions of paragraph 4 of regulation 3 of this Annex, oil tankers of 150 gross tonnage and above shall be provided with slop tank arrangements in accordance with the requirements of paragraphs 2.1 to 2.3 of this regulation. In oil tankers delivered on or before 31 December 1979, as defined in regulation 1.28.1, any cargo tank may be designated as a slop tank.
2.1 Adequate means shall be provided for cleaning the cargo tanks and transferring the dirty ballast residue and tank washings from the cargo tanks into a slop tank approved by the Administration.
2.2 In this system arrangements shall be provided to transfer the oily waste into a slop tank or combination of slop tanks in such a way that any effluent discharged into the sea will be such as to comply with the provisions of regulation 34 of this Annex.
2.3 The arrangements of the slop tank or combination of slop tanks shall have a capacity necessary to retain the slop generated by tank washings, oil residues and dirty ballast residues. The total capacity of the slop tank or tanks shall not be less than 3 per cent of the oil carrying capacity of the ship, except that the Administration may accept:

The entries in the Oil Record Book Part II, for ships holding an IOPP Certificate, shall be at least in English, French or Spanish. Where entries in an official language of the State whose flag the ship is entitled to fly are also used, this shall prevail in case of a dispute or discrepancy.
The Oil Record Book Part II shall be kept in such a place as to be readily available for inspection at all reasonable times and, except in the case of unmanned Ships under tow, shall be kept on board the Ship. It shall be preserved for a period of three years after the last entry has been made.
The competent authority of the Government of a Party to the Convention may inspect the Oil Record Book Part II on board any Ship to which this Annex applies while the Ship is in its port or offshore terminals and may make a copy of any entry in that book and may require the master of the Ship to certify that the copy is a true copy of such entry. Any copy so made which has been certified by the master of the Ship as a true copy of an entry in the Oil Record Book Part II shall be made admissible in any juridical proceedings as evidence of the facts stated in the entry. The inspection of an Oil Record Book Part II and taking of a certified copy by the competent authority under this paragraph shall be performed as expeditiously as possible without causing the ship to be unduly delayed.
