4.1 This section contains operational procedures in respect of tank cleaning, ballast and slops handling which must be followed in order to ensure compliance with the requirements of Annex II.

4.2 The following paragraphs outline the sequence of actions to be taken and contain the information essential to ensure that noxious liquid substances are discharged without posing a threat of harm to the marine environment.

4.3 Establish if the last cargo in the tank is included in the ship's approved list of noxious liquid substances (see table 1). If not included, no special tank cleaning, residue discharge, ballasting and deballasting procedures apply under the provisions of Annex II.

4.4 If the last cargo in the tank is included in the above-mentioned list, the information necessary to establish the procedures for discharging the residue of that cargo, cleaning, ballasting and deballasting the tanks, should take into account the following;
4.4.1 Category of substance
Obtain the category of the substance from table 1.
4.4.2 Stripping efficiency of tank pumping system
The contents of this section will depend on the design of the ship and whether it is a new ship or existing ship. (See flow diagrams - pumping/ stripping requirements.)
4.4.3 Vessel within or outside special area
This section should contain instructions on whether the tank washings can be discharged into the sea within a special area (as defined in section 1.3) or outside special area. The different requirements should be made clear and will depend on the design and trade of the ship.
4.4.4 Solidifying or high-viscosity substance
The properties of the substance should be obtained from the shipping documents.
4.4.5 Miscibility in water
This property of the substance should be obtained from table 1.

Note: This section should be completed only for existing ships and only for Category B substances.

4.4.6 Compatibility with slops containing other substances
This section should contain instructions on the permissible and non- permissible mixing of cargo slops. Reference should be made to compatibility guides.
4.4.7 Discharge to reception facility
This section should identify those substances the residues of which are required to be prewashed and discharged to a reception facility.
4.4.8 Discharging into the sea
This section should contain information on the factors to be considered in order to identify whether the residue/water mixtures are permitted to be discharged into the sea.
4.4.9 Use of cleaning agents or additives
This section should contain information on the use and disposal of cleaning agents (e.g. solvent used for tank cleaning) and additives to tank washing water (e.g. detergents).
4.4.10 Use of ventilation procedures for tank cleaning
This section should make reference to table 1 to ascertain the suitability of the use of ventilation procedures.

4.5 Having assessed the above information, the correct operational procedures to be followed should be identified using the instructions and flow diagrams in this section. Appropriate entries should be made in the Cargo Record Book indicating the procedure adopted.
This section should contain procedures, which will depend on the age of the ship and pumping efficiency, based on the Standards.
Examples of flow diagrams referred to in this section are given at addendum A and incorporate comprehensive requirements applicable to both new and existing ships. The Manual for a particular ship should only contain those requirements specifically applicable to that ship. The Manual should contain the following information and procedures.

(2) In the case of a ship of less than 400 tons gross tonnage other than an oil tanker whilst outside the special area, the Administration shall ensure that it is equipped as far as practicable and reasonable with installations to ensure the storage of oil residues on board and their discharge to reception facilities or into the sea in compliance with the requirements of paragraph (1)(b) of this Regulation.

(3) Whenever visible traces of oil are observed on or below the surface of the water in the immediate vicinity of a ship or its wake, Governments of Parties to the Convention should, to the extent they are reasonably able to do so, promptly investigate the facts bearing on the issue of whether there has been a violation of the provisions of this Regulation or Regulation 10 of this Annex. The investigation should include, in particular, the wind and sea conditions, the track and speed of the ship, other possible sources of the visible traces in the vicinity, and any relevant oil discharge records.

(4) The provisions of paragraph (1) of this Regulation shall not apply to the discharge of clean or segregated ballast. The provisions of sub-paragraph (1)(b) of this Regulation shall not apply to the discharge of oily mixture which without dilution has an iol content not exceeding 15 parts per million.

(5) No discharge into the sea shall contain chemicals or other substances in quantities or concentrations which are hazardous to the marine environment or chemicals or other substances introduced for the purpose of circumventing the conditions of discharge specified in this Regulation.

(6) The oil residues which cannot be discharged into the sea in compliance with paragraphs (1), (2) and (4) of this Regulation shall be retained on board or discharged to reception facilities.

Unified Interpretation

3 Controls of discharge of oil

Reg. 9(1)

3.1 Discharges from machinery space bilges of oil tankers

3.1.1 The wording "from machinery space bilges excluding cargo pump-room bilges of an oil tanker unless mixed with oil cargo residue" in regulation 9(1)(b) should be interpreted as follows:
.1 regulation 9(1)(a) applies to:
.1.1 discharges of oil or oily mixture from machinery space bilges of oil tankers where mixed with cargo oil residue or when transferred to slop tanks;and
.1.2 discharges from cargo pump-room bilges of oil tankers.
.2 Regulation 9(1)(b) applies to discharges from machinery space bilges of oil tankers other than those referred to above.

3.1.2 The above interpretation should not be construed as relaxing any existing prohibition of piping arrangements connecting the engine-room and slop tanks which may permit cargo to enter the machinery spaces. Any arrangements provided for machinery space bilge discharges into slop tanks should incorporate adequate means to prevent any backflow of liquid cargo or gases into the machinery spaces. Any such arrangements do not constitute a relaxation of the requirements of regulation 16 with respect to oil discharge monitoring and control system and oily-water separating equipment.

Reg.9(1)(a)

3.2 Total quantity of discharge

3.2.1 The phrase "the total quantity of the particular cargo of which the residue formed a part" in regulation 9(1)(a)(v) relates to the total quantity of the particular cargo which was carried on the previous voyage and should not be construed as relating only to the total quantity of cargo which was contained in the cargo tanks into which water ballast was subsequently loaded.

Reg.9(1), 10(3)

1. One of the conditions for the discharge of oil specified in regulations 9 and 10 is that the ship discharge through oily-water separating or filtering equipment, oil discharge monitoring and control system, and other related equipment. For existing ships, a three year period of grace is allowed for the installation of such equipment.

2. Regulations 9(1)(a)(vi) and (b)(v) refer to equipment as required by regulations 15 and 16 respectively. Therefore, during the three year period of grace, existing ships may discharge oily wastes under the conditions specified in regulations 9(1)(a)(i) through (v) and (b)(i) through (iv) without such equipment.

3. However, under regulation 10(3)(b)(v), one of the conditions for discharge of oily waste is that the ship has in operation oil filtering equipment complying with regulation 16. Therefore, within special areas, no discharge should be allowed for existing ships without oil filtering equipment during the three year period of grace.

4. Oil filtering equipment is not required for ships less than 10,000 grt so there is no period of grace for such installations.

Reg.9(4)

3.3 Discharges from ships of 400 tons gross tonnage and above but less than 10,000 tons gross tonnage within 12 miles from the nearest land
3.3.1 Ships of 400 grt and above but less than 10,000 grt, except those carrying large quantities of oil fuel are required to be fitted with oily-water separating equipment certified for an effluent with oil content of less than 100ppm complying with the provisions of Regulation 16(6). Such ships may, however, be fitted with oil filtering equipment certified for an effluent with oil content not exceeding 15 ppm. This equipment may or may not be provided with an alarm arrangement as referred to in Regulation 16(7).

3.3.2 Such ships, whether or not provided with alarm arrangements, may discharge, within 12 nautical miles from the nearest land but outside special areas, oily mixture which without dilution has an oil content not exceeding 15 ppm. It is, however, recommended that an alarm arrangement in accordance with Regulation 16(7) be provided on such ships and be in operation for such discharges, so that ship's crew can ascertain that the oil content of the effluent does not exceed 15 ppm.

Unified Interpretation

5 Fuel oil

5.1 Large quantities of oil fuel

5.1.1 The phrase "large quantities of oil fuel" in regulation 14(2) was formulated in drafting MARPOL 73/78 to take account of those ships which are required to stay at sea for extended periods because of the particular nature of their operation and trade. Under the circumstances considered these ships would be required to fill their empty oil fuel tanks with water ballast in order to maintain sufficient stability and safe navigation conditions.

5.1.2 Such ships may include inter alia certain large fishing vessels or ocean-going tugs. Certain other types of ships which for reasons of safety, such as stability, may be required to carry ballast in oil fuel tanks may also be included in this category.

5.2 Application of regulation 14(3)

5.2.1 The phrase "all other ships" in regulation 14(3) should include:
.1 new ships other than oil tankers of less than 4,000 tons gross tonnage;
.2 new oil tankers of less than 150 tons gross tonnage�Gand
.3 oil existing ships irrespective of tonnage.

5.2.2 When the separation of oil fuel tanks and water ballast tanks is unreasonable or impracticable for ships mentioned in paragraph 5.2.1 above, ballast water may be carried in oil fuel tanks, provided that such ballast water is discharged into the sea in compliance with regulation 9(1)(b), 10(2) or 10(3) or into reception facilities in compliance with regulation 10(4).

(1) Subject to the provisions of paragraphs (5) and (6) of this Regulation, oil tankers of 150 tons gross tonnage and above shall be provided with arrangements in accordance with the requirements of paragraphs (2) and (3) of this Regulation, provided that in the case of existing tankers the requirements shall apply three years after the date of entry into force of the present Convention.

(2) (a) 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. In existing oil tankers, any cargo tank may be designated as a slop tank.

(b) 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 9 of this Annex.

(c) The arrangements of the slop tank or combination of slop tanks shall have a capacity necessary to retain the slops generated by tank washing, oil residues and dirty ballast residues but the total shall be not less than 3 per cent of the oil carrying capacity of the ship, except that, where segregated ballast tanks are provided in accordance with Regulation 13 of this Annex, or where arrangements such as eductors involving the use of water additional to the washing water are not fitted, the Administration may accept 2 per cent. New oil tankers over 70,000 tons deadweight shall be provided with at least two slop tanks.
(d) Slop tanks shall be so designed particularly in respect of the position of inlets, outlets, baffles or weirs where fitted, so as to avoid excessive turbulence and entrainment of oil or emulsion with the water.

(3) (a) An oil discharge monitoring and control system approved by the Administration shall be fitted. In considering the design of the oil content meter to be incorporated in the system, the Administration shall have regard to the specification recommended by the Organization.* The system shall be fitted with a recording device to provide a continuous record of the discharge in litres per nautical mile and total quantity discharged, or the oil content and rate of discharge. This record shall be identifiable as to time and date and shall be kept for at least three years. The oil discharge monitor and control system shall come into operation when there is any discharge of effluent into the sea and shall be such as will ensure that any discharge of oily mixture is automatically stopped when the instantaneous rate of discharge of oil exceeds that permitted by Regulation 9(1)(a) of this Annex. Any failure of this monitoring and control system shall stop the discharge and be noted in the Oil Record Book. A manually operated alternative method shall be provided and may be used in the event of such failure, but the defective unit shall be made operable before the oil tanker commences its next ballast voyage unless it is proceeding to a repair port. Existing oil tankers shall comply with all of the provisions specified above except that the stopping of the discharge may be performed manually and the rate of discharge may be estimated from the pump characteristic.
(b) Effective oil/water interface detectors approved by the Administration shall be provided for a rapid and accurate determination of the oil/water interface in slop tanks and shall be available for use in other tanks where the separation of oil and water is effected and from which it is intended to discharge effluent direct to the sea.
(c) Instructions as to the operation of the system shall be in accordance with an operational manual approved by the Administration. They shall cover manual as well as automatic operations and shall be intended to ensure that at no time shall oil be discharged except in compliance with the conditions specified in Regulation 9 of this Annex .**

(4) The requirements of paragraphs (1), (2) and (3) of this Regulation shall not apply to oil tankers of less than 150 tons gross tonnage, for which the control of discharge of oil under Regulation 9 of this Annex shall be effected by the retention of oil on board with subsequent discharge of all contaminated washings to reception facilities. The total quantity of oil and water used for washing and returned to a storage tank shall be recorded in the Oil Record Book. This total quantity shall be discharged to reception facilities unless adequate arrangements are made to ensure that any effluent which is allowed to be discharged into the sea is effectively monitored to ensure that the provisions of Regulation 9 of this Annex are complied with.

(5) The Administration may waive the requirements of paragraphs (1), (2) and (3) of this Regulation for any oil tanker which engages exclusively on voyages both of 72 hours or less in duration and within 50 miles from the nearest land, provided that the oil tanker is not required to hold and does not hold an International Oil Pollution Prevention Certificate engaged exclusively in trades between ports or terminals within a State Party to the present Convention. Any waiver shall be subject to the requirement that the oil tanker shall retain on board all oily mixtures for subsequent discharge to reception facilities and to the determination by the Administration that facilities available to receive such oily mixtures are adequate. Any such waiver shall be subject to the requirement that the oil tanker shall retain on board all oily mixtures for subsequent discharge to reception facilities and to the determination by the Administration that facilities available to recieve such oily mixture are adequate.

(6) Where in the view of the Organization equipment required by Regulation 9(1)(a)(vi) of this Annex and specified in sub paragraph (3)(a) of this Regulation is not obtainable for the monitoring of discharge of light refined products (white oils), the Administration may waive compliance with such requirement, provided that discharge shall be permitted only in compliance with procedures established by the Organization which shall satisfy the conditions of Regulation 9(1)(a) of this Annex except the obligation to have an oil discharge monitoring and control system in operation. The Organization shall review the availability of equipment at intervals not exceeding twelve months.

(7) The requirements of paragraphs (1), (2) and (3) of this Regulation shall not apply to oil tankers carrying asphalt, for which the control of discharge of asphalt under Regulation 9 of this Annex shall be effected by the retention of asphalt residues on board with discharge of all contaminated washings to reception facilities.

7.1.2 The above equipment should be of adequate capacity to deal with the quantities of effluent to be discharged.

Reg. 16(2)

7.2 Control of 100 ppm discharge through 15 ppm separating/filtering equipment

7.2.1 If a ship of over 10,000 tons gross tonnage is fitted with a separator complying with Regulation 16(6) and a filtering system complying with Regulation 16(7) (see Regulation 16(2)(b)), and if the installation is in operation as a separator without using a filtering system, i.e. discharging of effluent with an oil content above 15 ppm at sea more than 12 nautical miles from the nearest land, then such an installation must be provided with an automatic monitoring and control device as required by Regulation 16(5).

7.3 Oil filtering equipment

Reg.16(1) and 16(2)(b)

7.3.1 Oil filtering equipment referred to in regulation 16(1) may include any combination of a separator, filter or coalescer, and also a single unit designed to produce an effluent with oil content of less than 100ppm.

7.3.2 Oil filtering equipment referred to in Regulation 16(2)(b) may include any combination of a separator, filter or coalescer, and also a single unit designed to produce an effluent with oil content not exceeding 15 ppm. If it is intended to use equipment attached to oily-water separating equipment certified for an effluent of less than 100 ppm under the terms of resolution A.393(X), the attached equipment should be approved under the terms of resolution A.444(XI), Annex, Appendix I, paragraph 3.17.

Reg.17 Tanks for oil residues (sludge)

(1) Every ship of 400 tons gross tonnage and above shall be provided with a tank or tanks of adequate capacity, having regard to the type of machinery and length of voyage, to receive the oily residue (sludge) which cannot be dealt with otherwise in accordance with the requirements of this Annex, such as those resulting from the purification of fuel and lubricating oils and oil leakages in the machinery spaces.

(2) In new ships, such tanks shall be designed and constructed so as to facilitate their cleaning and the discharge of residues to reception facilities. Existing ships shall comply with this requirement as far as is reasonable and practicable.

Unified Interpretation

8 Sludge tanks

8.1 Capacity of sludge tanks

8.1.1 To assist Administrations in determining the adequate capacity of sludge tanks, the following criteria may be used as guidance. The capacity of sludge tanks may, however, be calculated upon any other reasonable assumptions.
.1 For ships which do not carry ballast water in oil fuel tanks, the minimum sludge tank capacity(V1) should be calculated by the following formula:

where:
K1 = 0.01 for ships where heavy fuel oil is purified for main engine use, or 0.005 for ships using diesel oil or heavy fuel oil which does not require purification before use.
C = daily fuel oil consumption (metric tons),
D = maximum period of voyage between ports where sludge can be discharged ashore (days). In the absence of precise data a figure of 30 days should be used.
.2 When such ships are fitted with homogenizers, sludge incinerators or other recognized means on board for the control of sludge, the minimum sludge tank capacity (V1) should, in lieu of the above, be:
V1 = 1.for ships of 400 tons gross and above but less than 4,000 tons gross tonnage, or 2.for ships of 4,000 tons gross tonnage and above.
.3 For ships which carry ballast water in fuel oil tanks, the minimum sludge tank capacity(V2) should be calculated by the following formula:

where:
V1= sludge tank capacity specified in .1 or .2 above.
K2= 0.01 for heavy fuel oil bunker tanks, or 0.005 for diesel oil bunker tanks.
B = capacity of water ballast tanks which can also be used to carry oil fuel(metric tons).

Reg.24 Limitation of size and arrangement of cargo tanks

(1) Every new oil tanker shall comply with the provisions of this Regulation. Every existing oil tanker shall be required, within two years after the date of entry into force of the present Convention, to comply with the provisions of this Regulation if such a tanker falls into either of the following categories:
(a) a tanker, the delivery of which is after 1 January 1977; or
(b) a tanker to which both the following conditions apply:
(See paragraph 1.2 of the unified interpretation - unforeseen delay in delivery of ships.)
(i) delivery is not later than 1 January 1977; and
(ii) the building contract is placed after 1 January 1974, or in cases where no building contract has previously been placed, the keel is laid or the tanker is at a similar stage of construction after 30 June 1974.

(2) Cargo tanks of oil tankers shall be of such size and arrangements that the hypothetical outflowOc or Os calculated in accordance with the provisions of Regulation 23 of this Annex anywhere in the length of the ship does not exceed 30,000 cubic metres or 400³√ 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 seventy-five 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 13 of this Annex, the permitted volume of a wing cargo oil tank situated between two segregated ballast tanks, each exceeding l c in length, may be increased to the maximum limit of hypothetical oil outflow provided that the width of the wing tanks exceeds t c .

(4) The length of each cargo tank shall not exceed 10 metres or one of the following values, whichever is the greater:

(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 t c from the ship's side or less than v c 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.

Reg.25 Subdivision and stability

(1) Every new oil tanker 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 specific gravities of the cargo. Such damage shall be applied to all conceivable locations along the length of the ship as follows:

(a) in tankers of more than 225 metres in length, anywhere in the ship's length;
(b) in tankers of more than 150 metres, but not exceeding 225 metres in length, anywhere in the ship's length except involving either after of forward bulkhead bounding the machinery space located aft. The machinery space shall be treated as a single floodable compartment;
(c) 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 residue, shall not be considered.

(2) The following provisions regarding the extent and the character of the assumed damage shall apply:

(a) The extend of side or bottom damage shall be as specified in Regulation 22 of this Annex, except that the longitudinal extent of bottom damage within 0.3L from the forward perpendicular shall be the same as for side damage, as specified in Regulation 22(1)(a)(i) of this Annex. If any damage of lesser extend results in a more severe condition such damage shall be assumed.

(b) Where the damage involving transverse bulkheads is envisaged as specified in sub-paragraphs (1)(a) and (b) of this Regulation, transverse watertight bulkheads shall be spaced at least at a distance equal to the longitudinal extent of assumed damage specified in sub-paragraph (a) of this paragraph in order to be considered effective. Where transverse bulkheads 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.

(c) Where the damage between adjacent transverse watertight bulkheads is envisaged as specified in sub-paragraph (1)(c) of this Regulation, no main transverse bulkhead or a transverse bulkhead bounding side tanks or double bottom tanks shall be assumed damaged, unless:
(i) the spacing of the adjacent bulkheads is less than the longitudinal extent of assumed damage specified in sub-paragraph (a) of this paragraph; or
(ii) there is a step or a 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 tank top shall not be regarded as a step for the purpose of this Regulation.

(d) 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:
(a) 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 side scuttles of the non-opening type.

(b) In the final stage of flooding, the angle of heel due to unsymmetrical flooding shall not exceed 25 degrees, provided that this angle may be increased up to 30 degrees if no deck edge immersion occurs.

(c) 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 degrees beyond the position of equilibrium in association with a maximum residual righting lever of at least 0.1 metre. The Administrations shall give consideration to be potential hazard presented by protected or unprotected openings which may become temporarely immersed within the range of residual stability.

(d) The Administration shall be satisfied that the stability is sufficient during intermediate stages of flooding.

(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, specific gravities and the free surface effect of liquids. The calculations shall be based on the following:
(a) Account shall be taken of any empty or partially filled tank, the specific gravity of cargoes carried, as well as any outflow of liquids from damaged compartments.
(b) The permeabilities are assumed as follows:

* Whichever results in the more severe requirements
* The permeability of partially filled compartments shall be consistent with the amount of liquid carried.

(c) 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 sub-paragraph (3)(a) of this Regulation in respect of these intact spaces are complied with. Hinged watertight doors may be acceptable in watertight bulkheads in the superstructure.
(d) The free surface effect shall be calculated at an angle of heel of 5 degrees 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 degrees for partially filled tanks.
(e) 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 surfaces is the greatest.

(5) The Master of every new oil tanker and the person in charge of a new non-self-propelled oil tanker to which this Annex applies shall be supplied in an approved form with:
(a) information relative to loading and distribution of cargo necessary to ensure compliance with the provisions of this Regulation; and
(b) 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 sub-paragraph (1)(c) of this Regulation.

Part I Machinery space operations

Form of Oil Record Book

Oil Record Book

Part I - Machinery space operation

(All Ships)

Name of Ship: _________________________

Distinctive number or letters: _________________________

Gross tonnage: _________________________

Period from: _________________________ to: _________________________

Note: Oil Record Book Part I shall be provided to every oil tanker of 150 gross tonnage and above and every ship of 400 gross tonnage and above, other than oil tankers, to record relevant machinery space operations. For oil tankers, Oil Record Book Part II shall also be provided to record relevant cargo/ballast operations.

Introduction

The following pages of this section show a comprehensive list of items of machinery space operations which are, when appropriate, to be recorded in the Oil Record Book Part I in accordance with regulation 17 of Annex I of the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL 73/78). The items have been grouped into operational sections, each of which is denoted by a letter Code.

When making entries in the Oil Record Book Part I, the date, operational Code and item number shall be inserted in the appropriate Columns and the required particulars shall be recorded chronologically in the blank spaces.

Each completed operation shall be signed for and dated by the officer or officers in charge. The master of the Ship shall sign each completed page.

The Oil Record Book Part I contains many references to oil quantity. The limited accuracy of tank Measurement devices, temperature variations and clingage will affect the accuracy of these readings. The entries in the Oil Record Book Part I should be considered accordingly.

In the event of accidental or other exceptional discharge of oil statement shall be made in the Oil Record Book Part I of the circumstances of, and the reasons for, the discharge.

Any failure of the oil filtering equipment shall be noted in the Oil Record Book Part I.

The entries in the Oil Record Book Part I, for ships holding an IOPP Certificate, shall be at least in English, French or Spanish. Where entries in 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 I 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 I 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 I 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 I and the 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.

Introduction

The following pages of this section show a comprehensive list of items of cargo and ballast operations which are, when appropriate, to be recorded in the Oil Record Book Part II in accordance with regulation 36 of Annex I of the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL 73/78). The items have been grouped into operational section, each of which is denoted by a code letter.

When making entries in the Oil Record Book Part II, the date, operational code and item number shall be inserted in the appropriate columns and the required particulars shall be recorded chronologically in the blank spaces.

Each completed operation shall be signed for and dated by the officer or officers in charge. Each completed page shall be countersigned by the master of the ship.

In respect of the oil tankers engaged in specific trades in accordance with regulation 2.5 of Annex I of MARPOL 73/78, appropriate entry in the Oil Record Book Part II shall be endorsed by the competent port State authority*.

The Oil Record Book Part II contains many references to oil quantity. The limited accuracy of tank Measurement devices, temperature variations and clingage will affect the accuracy of these readings. The entries in the Oil Record Book Part II should be considered accordingly.

In the event of accidental or other exceptional discharge of oil a statement shall be made in the Oil Record Book Part II of the circumstances of, and the reasons for, the discharge.

Any failure of the oil discharge monitoring and control system shall be noted in the Oil Record Book Part II.

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.

Duration and validity of certificate

1 An International Oil Pollution Prevention Certificate shall be issued for a period specified by the Administration, which shall not exceed five years.

2.1 Notwithstanding the requirements of paragraph 1 of this regulation, when the renewal survey is completed within 3 months before the expiry date of the existing certificate, the new certificate shall be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of expiry of the existing certificate.

2.2 When the renewal survey is completed after the expiry date of the existing certificate, the new certificate shall be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of expiry of the existing certificate.

2.3 When the renewal survey is completed more than 3 months before the expiry date of the existing certificate, the new certificate shall be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of completion of the renewal survey.

3 If a certificate is issued for a period of less than 5 years, the Administration may extend the validity of the certificate beyond the expiry date to the maximum period specified in paragraph 1 of this regulation, provided that the surveys referred to in regulations 6.1.3 and 6.1.4 of this Annex applicable when a certificate is issued for a period of 5 years are carried out as appropriate.

4 If a renewal survey has been completed and a new certificate cannot be issued or placed on board the ship before the expiry date of the existing certificate, the person or organization authorized by the Administration may endorse the existing certificate and such a certificate shall be accepted as valid for a further period which shall not exceed 5 months from the expiry date.

5 If a ship at the time when a certificate expires is not in a port in which it is to be surveyed, the Administration may extend the period of validity of the certificate but this extension shall be granted only for the purpose of allowing the ship to complete its voyage to the port in which it is to be surveyed, and then only in cases where it appears proper and reasonable to do so. No certificate shall be extended for a period longer than 3 months, and a ship to which an extension is granted shall not, on its arrival in the port in which it is to be surveyed, be entitled by virtue of such extension to leave that port without having a new certificate. When the renewal survey is completed, the new certificate shall be valid to a date not exceeding 5 years from the date of expiry of the existing certificate before the extension was granted.

6 A certificate issued to a ship engaged on short voyages which has not been extended under the foregoing provisions of this regulation may be extended by the Administration for a period of grace of up to one month from the date of expiry stated on it. When the renewal survey is completed, the new certificate shall be valid to a date not exceeding 5 years from the date of expiry of the existing certificate before the extension was granted.

7 In special circumstances, as determined by the Administration, a new certificate need not be dated from the date of expiry of the existing certificate as required by paragraphs 2.2, 5 or 6 of this regulation. In these special circumstances, the new certificate shall be valid to a date not exceeding 5 years from the date of completion of the renewal survey.

8 If an annual or intermediate survey is completed before the period specified in regulation 6 of this Annex, then:

.1 the anniversary date shown on the certificate shall be amended by endorsement to a date which shall not be more than 3 months later than the date on which the survey was completed;

.2 the subsequent annual or intermediate survey required by regulation 6.1 of this Annex shall be completed at the intervals prescribed by that regulation using the new anniversary date; and

.3 the expiry date may remain unchanged provided one or more annual or intermediate surveys, as appropriate, are carried out so that the maximum intervals between the surveys prescribed by regulation 6.1 of this Annex are not exceeded. 9 A certificate issued under regulation 7 or 8 of this Annex shall cease to be valid in any of the following cases:

.1 if the relevant surveys are not completed within the periods specified under regulation 6.1 of this Annex;

.2 if the certificate is not endorsed in accordance with regulation 6.1.3 or 6.1.4 of this Annex; or

.3 upon transfer of the ship to the flag of another State. A new certificate shall only be issued when the Government issuing the new certificate is fully satisfied that the ship is in compliance with the requirements of regulations 6.4.1 and 6.4.2 of this Annex. In the case of a transfer between Parties, if requested within 3 months after the transfer has taken place, the Government of the Party whose flag the ship was formerly entitled to fly shall, as soon as possible, transmit to the Administration copies of the certificate carried by the ship before the transfer and, if available, copies of the relevant survey reports.

Regulation 12A Oil fuel tank protection

Ingangsdatum: 01-08-2007

Oil fuel tank protection

This regulation shall apply to all ships with an aggregate oil fuel capacity of 600 m3 and above which are delivered on or after 1 August 2010, as defined in regulation 1.28.9 of this Annex.
The application of this regulation in determining the location of tanks used to carry oil fuel does not govern over the provisions of regulation 19 of this Annex.
For the purpose of this regulation, the following definitions shall apply:
1. “Oil fuel” means any oil used as fuel oil in connection with the propulsion and auxiliary machinery of the ship in which such oil is carried.
2. “Load line draught (d_S)” is the vertical distance, in metres, from the moulded baseline at mid-length to the waterline corresponding to the summer freeboard draught to be assigned to the ship.
3. “Light ship draught” is the moulded draught amidships corresponding to the lightweight.
4. “Partial load line draught (d_P)” is the light ship draught plus 60% of the difference between the light ship draught and the load line draught d_S. The partial load line draught (d_p) shall be measured in metres.
5. “Waterline (d_B)” is the vertical distance, in metres, from the moulded baseline at mid-length to the waterline corresponding to 30% of the depth D_S.
6. “Breadth (B_S)” is the greatest moulded breadth of the ship, in metres, at or below the deepest load line draught (d_S).
7. “Breadth (B_B)” is the greatest moulded breadth of the ship, in metres, at or below the waterline (d_B).
8. “Depth (D_S)” is the moulded depth, in metres, measured at mid-length to the upper deck at side. For the purpose of the application, “upper deck” means the highest deck to which the watertight transverse bulkheads except aft peak bulkheads extend.
9. “Length (L)” means 96% of the total length on a waterline at 85% of the least moulded depth measured from the top of the keel, or the length from the foreside of the stem to the axis of the rudder stock on that waterline, if that be greater. In ships designed with a rake of keel the waterline on which this length is measured shall be parallel to the designed waterline. The length (L) shall be measured in metres.
10. “Breadth (B)” means the maximum breadth of the ship, in metres, measured amidships to the moulded line of the frame in a ship with a metal shell and to the outer surface of the hull in a ship with a shell of any other material.
11. “Oil fuel tank” means a tank in which oil fuel is carried, but excludes those tanks which would not contain oil fuel in normal operation, such as overflow tanks.
12. “Small oil fuel tank” is an oil fuel tank with a maximum individual capacity not greater than 30 m³.
13. “C” is the ship’s total volume of oil fuel, including that of the small oil fuel tanks, in m³, at 98% tank filling.
14. “Oil fuel capacity” means the volume of a tank in m³, at 98% filling.
The provisions of this regulation shall apply to all oil fuel tanks except small oil fuel tanks, as defined in 3.12, provided that the aggregate capacity of such excluded tanks is not greater than 600 m³.
Individual oil fuel tanks shall not have a capacity of over 2,500 m³.
For ships, other than self-elevating drilling units, having an aggregate oil fuel capacity of 600 m³ and above, oil fuel tanks shall be located above the moulded line of the bottom shell plating nowhere less than the distance h as specified below:

h = B/20m or,

h = 2.0 m, whichever is the lesser.

The minimum value of h = 0.76 m

In the turn of the bilge area and at locations without a clearly defined turn of the bilge, the oil fuel tank boundary line shall run parallel to the line of the midship flat bottom as shown in Figure 1.

Figure 1 – Oil fuel tank boundary lines for the purpose of paragraph 6
For ships having an aggregate oil fuel capacity of 600 m³ or more but less than 5,000 m³, oil fuel tanks shall be located inboard of the moulded line of the side shell plating, nowhere less than the distance w which, as shown in Figure 2, is measured at any cross-section at right angles to the side shell, as specified below:

w = 0.4 + 2.4 C/20,000 m

The minimum value of w = 1.0 m, however for individual tanks with an oil fuel capacity of less than 500 m³ the minimum value is 0.76 m.
For ships having an aggregate oil fuel capacity of 5,000 m³ and over, oil fuel tanks shall be located inboard of the moulded line of the side shell plating, nowhere less than the distance w which, as shown in Figure 2, is measured at any cross-section at right angles to the side shell, as specified below:

w = 0.5 + C/20,000 m or

w = 2.0 m, whichever is the lesser.

The minimum value of w = 1.0 m

Figure 2 – Oil fuel tank boundary lines for the purpose of paragraphs 7 and 8
Lines of oil fuel piping located at a distance from the ship’s bottom of less than h, as defined in paragraph 6, or from the ship’s side less than w, as defined in paragraphs 7 and 8 shall be fitted with valves or similar closing devices within or immediately adjacent to the oil fuel tank. These valves shall be capable of being brought into operation from a readily accessible enclosed space the location of which is accessible from the navigation bridge or propulsion machinery control position without traversing exposed freeboard or superstructure decks. The valves shall close in case of remote control system failure (fail in a closed position) and shall be kept closed at sea at any time when the tank contains oil fuel except that they may be opened during oil fuel transfer operations.
Suction wells in oil fuel tanks may protrude into the double bottom below the boundary line defined by the distance h provided that such wells are as small as practicable and the distance between the well bottom and the bottom shell plating is not less than 0.5 h.

Alternatively to paragraphs 6 and either 7 or 8, ships shall comply with the accidental oil fuel outflow performance standard specified below:

The level of protection against oil fuel pollution in the event of collision or grounding shall be assessed on the basis of the mean oil outflow parameter as follows:

O_M< 0.0157-1.14E-6·C                             600 m3<C < 5,000 m3
OM< 0.010                                                  C >5,000 m3
Where   OM= mean oil outflow parameter;             C = total oil fuel volume.
The following general assumption shall apply when calculating the mean oil outflow parameter:
1. the ship shall be assumed loaded to the partial load line draught d_P without trim or heel;
2. all oil fuel tanks shall be assumed loaded to 98% of their volumetric capacity;
3. the nominal density of the oil fuel () shall generally be taken as 1,000 kg/m³. If the density of the oil fuel is specifically restricted to a lesser value, the lesser value may be applied; and
4. for the purpose of these outflow calculations, the permeability of each oil fuel tank shall be taken as 0.99, unless proven otherwise.
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 a non-dimensional oil outflow parameter O_M, as follows:
  
  OM= (0.4 OMS+ 0.6 OMB) / C
  where:OMS = mean outflow for side damage, in m3OMB = mean outflow for bottom damage, in m3C = total oil fuel volume.
2. For bottom damage, independent calculations for mean outflow shall be done for 0 m and 2.5 m tide conditions, and then combined as follows:O_MB = 0.7 O_MB(0) + 0.3 O_MB(2.5)
  
  where:
  
  O_MB(0) = mean outflow for 0 m tide condition, and
  O_MB(2.5)= mean outflow for minus 2.5 m tide condition, in m³

The mean outflow for side damage O_MS shall be calculated as follows:

Where
i	=	represents each oil fuel tank under consideration;
n	=	total number of oil fuel tanks;
PS_(i)	=	the probability of penetrating oil fuel tank i from side damage, calculated in accordance with paragraph 11.6 of this regulation;
OS_(i)	=	the outflow, in m³, from side damage to oil fuel tank i, which is assumed equal to the total volume in oil fuel tank i at 98% filling.

The mean outflow for bottom damage shall be calculated for each tidal condition as follows:

_Where
_i	₌	_{represents each oil fuel tank under consideration;}
_n	₌	_{total number of oil fuel tanks;}
_{P_B(i)}	₌	_{the probability of penetrating oil fuel tank i from bottom damage, calculated in accordance with paragraph 11.7 of this regulation;}
_{O_B(i)}	₌	_{the outflow from oil fuel tank i, in m³, calculated in accordance with paragraph 11.5.3 of this regulation; and}
_{C_DB(i)}	₌	_{factor to account for oil capture as defined in paragraph 11.5.4.}

Where

i, n, P_B(i), C_DB(i)
=
as defined in subparagraph .1 above

O_B(i)
=
the outflow from oil fuel tank i, in m³, after tidal change.

The oil outflow O_B(i) for each oil fuel tank shall be calculated based on pressure balance principles, in accordance with the following assumptions:

The ship shall be assumed stranded with zero trim and heel, with the stranded draught prior to tidal change equal to the partial load line draught d_P.

The oil fuel level after damage shall be calculated as follows:

Where
h_F	=	the height of the oil fuel surface above Z_l, in m;
t_C	=	the tidal change, in m. Reductions in tide shall be expressed as negative values;
Z₁	=	the height of the lowest point in the oil fuel tank above the baseline, in m;
	=	density of seawater, to be taken as 1,025 kg/m³; and,
	=	nominal density of the oil fuel, as defined in 11.2.3.

The oil outflow O_B(i) for any tank bounding the bottom shell plating shall be taken not less than the following formula, but no more than the tank capacity:

O_B(i) = HW . A

Where

H_W

1.0 m, when Y_B = 0

_{H_W}

B_B/50 but not greater than 0.4 m, when Y_B is greater than B_B/5 or 11.5 m, whichever is less

“HW” is to be measured upwards from the midship flat bottom line. In the turn of the bilge area and at locations without a clearly defined turn of the bilge, H_W is to be measured from a line parallel to the midship flat bottom, as shown for distance “h” in Figure 1.

For Y_B values outboard B_B/5 or 11.5 m, whichever is less, H_W is to be linearly interpolated.

Y_B

the minimum value of Y_B over the length of the oil fuel tank, where at any given location, Y_B is the transverse distance between the side shell at waterline d_B and the tank at or below waterline d_B.

the maximum horizontal projected area of the oil fuel tank up to the level of H_W from the bottom of the tank.

Figure 3 – Dimensions for calculation of the minimum oil outflow for the purpose of subparagraph 11.5.3.3

In the case of bottom damage, a portion from the outflow from an oil fuel tank may be captured by non-oil compartments. This effect is approximated by application of the factor C_DB(i) for each tank, which shall be taken as follows:

C_DB(i)
=
0.6 for oil fuel tanks bounded from below by non-oil compartments;

C_DB(i)
=
1 otherwise.

The probability P_S of breaching a compartment from side damage shall be calculated as follows:

P_S = P_SL. P_SV. P_ST

_Where
_{P_SL}	₌	_{(1 – P_Sf– PSa) = probability the damage will extend into the longitudinal zone bounded by Xaand Xf;}
_{_{P_SV}}	₌	_{(1 – P_Su – P_Sl) = probability the damage will extend into the vertical zone bounded by Z_l and Z_u;}
_{_{P_ST}}	₌	_{(1 – P_Sy) = probability the damage will extend transversely beyond the boundary defined by y;}

P_Sa, P_Sf, P_Su and P_Sl shall be determined by linear interpolation from the table of probabilities for side damage provided in 11.6.3, and P_Sy shall be calculated from the formulas provided in 11.6.3, where:

P_Sa	=	the probability the damage will lie entirely aft of location X_a/L;
P_Sf	=	the probability the damage will lie entirely forward of location Xf/L;
_{P_Si}	=	probability the damage will lie entirely below the tank;
_{P_Su}	=	probability the damage will lie entirely above the tank; and
_{P_Sy}	=	probability the damage will lie entirely outboard the tank.
Compartment boundaries X_a, X_f, Z_l, Z_u and y shall be developed as follows:
_{X_a}	=	the longitudinal distance from aft terminal of L to the aft most point on the compartment being considered, in m;
_{X_f}	=	the longitudinal distance from aft terminal of L to the foremost point on the compartment being considered, in m;
_{Z_l}	=	the vertical distance from the moulded baseline to the lowest point on the compartment being considered, in m. Where Z_l is greater than D_S, Z_l shall be taken as D_S;
_{Z_u}	=	the vertical distance from the moulded baseline to the highest point on the compartment being considered, in m. Where Z_u is greater than D_S, Z_u shall be taken as D_S; and,
y	=	the minimum horizontal distance measured at right angles to the centreline between the compartment under consideration and the side shell, in m¹.

In way of the turn of the bilge, y need not to be considered below a distance h above baseline, where h is lesser of B/10, 3 m or the top of the tank.

The capacity of the segregated ballast tanks shall be so determined that the ship may operate safely on ballast voyages without recourse to the use of cargo tanks for water ballast except as provided for in paragraph 3 or 4 of this regulation. In all cases, however, the capacity of segregated ballast tanks shall be at least such that, in any ballast condition at any part of the voyage, including the conditions consisting of lightweight plus segregated ballast only, the ship's draughts and trim can meet the following requirements:
1. the moulded draught amidships (dm) in metres (without taking into account any ship's deformation) shall not be less than:
  
  d_m = 2.0 + 0.02L
2. the draughts at the forward and after perpendiculars shall correspond to those determined by the draught amidships (dm) as specified in paragraph 2.1 of this regulation, in association with the trim by the stern of not greater than 0.015L; and
3. in any case the draught at the after perpendicular shall not be less than that which is necessary to obtain full immersion of the propeller(s).
In no case shall ballast water be carried in cargo tanks, except:
1. on those rare voyages when weather conditions are so severe that, in the opinion of the master, it is necessary to carry additional ballast water in cargo tanks for the safety of the ship; and
2. in exceptional cases where the particular character of the operation of an oil tanker renders it necessary to carry ballast water in excess of the quantity required under paragraph 2 of this regulation, provided that such operation of the oil tanker falls under the category of exceptional cases as established by the Organization.
  
  Such additional ballast water shall be processed and discharged in compliance with regulation 34 of this Annex and an entry shall be made in the Oil Record Book Part II referred to in regulation 36 of this Annex.
In the case of crude oil tankers, the additional ballast permitted in paragraph 3 of this regulation shall be carried in cargo tanks only if such tanks have been crude oil washed in accordance with regulation 35 of this Annex before departure from an oil unloading port or terminal.
Notwithstanding the provisions of paragraph 2 of this regulation the segregated ballast conditions for oil tankers less than 150 metres in length shall be to the satisfaction of the Administration.

Crude oil tankers of 40,000 tonnes deadweight and above delivered on or before 1 June 1982qqqq

Subject to the provisions of paragraph 7 of this regulation every crude oil tanker of 40,000 tonnes deadweight and above delivered on or before 1 June 1982, as defined in regulation 1.28.3, shall be provided with segregated ballast tanks and shall comply with the requirements of paragraphs 2 and 3 of this regulation.
Crude oil tankers referred to in paragraph 6 of this regulation may, in lieu of being provided with segregated tanks operate with a cargo tank cleaning procedure using crude oil washing in accordance with regulation 33 and 35 of this Annex unless the crude oil tanker is intended to carry crude oil which is not suitable for crude oil washing.

2. comply, if applicable, with the requirements of regulation 28.6.
The entire cargo tank length shall be protected by ballast tanks or spaces other than tanks that carry oil as follows:
1. Wing tanks or spaces
  Wing tanks or spaces shall extend either for the full depth of the ship's side or from the top of the double bottom to the uppermost deck, disregarding a rounded gunwale where fitted. They shall be arranged such that the cargo tanks are located inboard of the moulded line of the side shell plating nowhere less than the distance w which, as shown in figure 1 is measured at any cross-section at right angles to the side shell, as specified below:
  
  w = 2.0 m, whichever is the lesser.
  
  The minimum value of w = 1.0 m.
2. Double bottom tanks or spaces
  At any cross-section the depth of each double bottom tank or space shall be such that the distance h between the bottom of the cargo tanks and the moulded line of the bottom shell plating measured at right angles to the bottom shell plating as shown in figure 1 is not less than specified below:
  
  h = B/15 (m) or
  
  h = 2.0 m, whichever is the lesser.
  
  The minimum value of h = 1.0 m.
3. Turn of the bilge area or at locations without a clearly defined turn of the bilge
  When the distances h and w are different, the distance w shall have preference at levels exceeding 1.5h above the baseline as shown in figure 1.
4. The aggregate capacity of ballast tanks
  On crude oil tankers of 20,000 tonnes deadweight and above and product carriers of 30,000 tonnes deadweight and above, the aggregate capacity of wing tanks, double bottom tanks, forepeak tanks and after peak tanks shall not be less than the capacity of segregated ballast tanks necessary to meet the requirements of regulation 18 of this Annex. Wing tanks or spaces and double bottom tanks used to meet the requirements of regulation 18 shall be located as uniformly as practicable along the cargo tank length. Additional segregated ballast capacity provided for reducing longitudinal hull girder bending stress, trim, etc., may be located anywhere within the ship.
5. Suction wells in cargo tanks
  Suction wells in cargo tanks may protrude into the double bottom below the boundary line defined by the distance h 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.
6. Ballast and cargo piping
  
  Ballast piping and other piping such as sounding and vent piping to ballast tanks shall not pass through cargo tanks. Cargo piping and similar piping to cargo tanks shall not pass through ballast tanks. Exemptions to this requirement may be granted for short lengths of piping, provided that they are completely welded or equivalent.

The following applies for double bottom tanks or spaces:

Double bottom tanks or spaces as required by paragraph 3.2 of this regulation may be dispensed with, provided that the design of the tanker is such that the cargo and vapour pressure exerted on the bottom shell plating forming a single boundary between the cargo and the sea does not exceed the external hydrostatic water pressure, as expressed by the following formula:

where:

h_c	=	height of cargo in contract with the bottom shell plating in metres
	=	maximum cargo density in kg/m³
d_n	=	minimum operating draught under any expected loading condition in metres
	=	density of seawater in kg/m³
p	=	maximum set pressure above atmospheric pressure (gauge pressure) of pressure/vacuum valve provided for the cargo tank in Pa
f	=	safety factor = 1.1
g	=	standard acceleration of gravity (9.81 m/s²)

Any horizontal partition necessary to fulfil the above requirements shall be located at a height not less than B/6 or 6 m, whichever is the lesser, but not more than 0.6D, above the baseline where D is the moulded depth amidships.
The location of wing tanks or spaces shall be as defined in paragraph 3.1 of this regulation except that, below a level 1.5 h above the baseline where h is as defined in paragraph 3.2 of this regulation, the cargo tank boundary line may be vertical down to the bottom plating, as shown in figure 2.

Other methods of design and construction of oil tankers may also be accepted as alternatives to the requirements prescribed in paragraph 3 of this regulation, provided that such methods ensure at least the same level of protection against oil pollution in the event of collision or stranding and are approved in principle by the Marine Environment Protection Committee based on guidelines developed by the Organization*.
Every oil tanker of less than 5,000 tonnes deadweight shall comply with paragraphs 3 and 4 of this regulation, or shall:
1. at least be fitted with double bottom tanks or spaces having such a depth that the distance h specified in paragraph 3.2 of this regulation, complies with the following:
  
  h = B/15 (m)
  
  with a minimum value of h = 0.76 m;
  
  in the turn of the bilge area and at locations without a clearly defined turn of the bilge, the cargo tank boundary line shall run parallel to the line of the midship flat bottom as shown in figure 3; and
2. be provided with cargo tanks so arranged that the capacity of each cargo tank does not exceed 700 m3 unless wing tanks or spaces are arranged in accordance with paragraph 3.1 of this regulation, complying with the following:
  with a minimum value of w = 0.76 m.
Oil shall not be carried in any space extending forward of a collision bulkhead located in accordance with regulation II-1/11 of the International Convention for the Safety of Life at Sea, 1974, as amended. An oil tanker that is not required to have a collision bulkhead in accordance with that regulation shall not carry oil in any space extending forward of the transverse plane perpendicular to the centreline that is located as if it were a collision bulkhead located in accordance with that regulation.
In approving the design and construction of oil tankers to be built in accordance with the provisions of this regulation, Administrations shall have due regard to the general safety aspects including the need for the maintenance and inspections of wing and double bottom tanks or spaces.

For the purpose of this regulation, the following definitions shall apply:
1. "Load line draught (d_S)" 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 d_S, notwithstanding assigned draughts that may exceed d_S, such as the tropical loadline.
2. "Waterline (d_B)" is the vertical distance, in metres, from the moulded baseline at mid-length to the waterline corresponding to 30% of the depth D_S.

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.
The following assumptions shall be used when combining the oil outflow parameters:

  where:
  O_MS = mean outflow for side damage, in m³; and
  
  O_MB= 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:
  
  O_MB= (0.7 O_MB(0) + 0.3 O_MB(2.5)) / C
  
  Where:
  O_MB(0)= mean outflow for 0 m tide condition; and
  
  O_MB(2.5)= mean outflow for minus 2.5 m tide condition, in m³.

For cargo tanks bounded by the bottom shell, unless proven otherwise, oil outflow O_B(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.

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 C_DB(i) for each tank, which shall be taken as follows:

C_DB(i) = 0.6 for cargo tanks bounded from below by non-oil compartments;

Compartment boundaries X_a, X_f, Y_p, Y_s, and z shall be developed as follows:
X_aand X_f are as defined in paragraph 8.2 of this regulation;
Y_p	=	the transverse distance from the port-most point on the compartment located at or below the waterline d_B, to a vertical plane located B_B/2 to starboard of the ship's centreline, in metres;
Y_s	=	the transverse distance from the starboard-most point on the compartment located at or below the waterline d_B, to a vertical plane located B_B/2 to starboard of the ship's centreline, in metres; and

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.²
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.
The following provisions regarding piping arrangements shall apply:
1. Lines of piping that run through cargo tanks in a position less than 0.30B_s from the ship's side or less than 0.30D_s 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.

1 For symmetrical tank arrangements, damages are considered for one side of the ship only, in which case all "y" dimensions are to be measured from that same side. For asymmetrical arrangements refer to the Explanatory Notes on matters related to the accidental oil outflow performance, adopted by the Organization by resolution MEPC.122(52).

Hypothetical outflow of oil

1 The hypothetical outflow of oil in the case of side damage (O_c) and bottom damage (O_s) 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:
		(I)
2	For bottom damages:
		(II)

Where:

W_i	=	volume of a wing tank in cubic metres assumed to be breached by the damage as specified in regulation 24 of this Annex; W_i for a segregated ballast tank may be taken equal to zero.
C_i	=	volume of a centre tank in cubic metres assumed to be breached by the damage as specified in regulation 24 of this Annex; C_i for a segregated ballast tank may be taken equal to zero.
K_i	=		;when b_i is equal to or greater than t_c, K_i shall be taken equal to zero.
Z_i	=		; when h_i is equal to or greater than v_s, Z_i shall be taken equal to zero.
b_i	=	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.
h_i	=	minimum depth of the double bottom in metres under consideration; where no double bottom is fitted, h_i 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 l_c as defined in regulation 24 of this Annex is located between wing oil tanks, O_c in formula (I) may be calculated on the basis of volume W_i 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 S_i 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 .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. 3.2 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. 3.3 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: (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 28 Subdivision and damage stability

Ingangsdatum: 01-01-2007

Subdivision and damage stability

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.

The following provisions regarding the extent and the character of the assumed damage shall apply:

Side damage:

Longitudinal extent:

or 14.5 metres, whichever is less

Transverse extent (inboard from the ship's side at right angles to the centreline at the level of the
summer freeboard):

or 11.5 metres, whichever is less.

vertical extent

From the moulded line of the bottom
shell plating at centreline, upwards
without limit.

Bottom damage

For 0.3L from the
forward perpendicular
of the ship

Any other part of the
ship

Longitudinal extent:

or 14.5 metres
whichever is less

or 5 metres
whichever is less

Transverse extent:

or 10 metres,
whichever is less

or 5 metres,
whichever is less

Vertical extent:

or 6 metres, whichever is
less, measured from the
moulded line of the bottom
shell plating at centreline

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.
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.
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.
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.

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 30º 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 20º beyond the position of equilibrium in association with a maximum residual righting lever of at least 0.1 metre within the 20º 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.
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:
  Spaces
  Permeabilities
  Appropriated to stores 0.60
  Occupied by accomodation 0.95
  Occupied by machinery 0.85
  Voids 0.95
  Intended for consumable liquids
  0 to 0.95*
  Intended for other liquids 0 to 0.95*
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 5º for each individual compartment. The Administration may require or allow the free surface corrections to be calculated at an angle of heel greater than 5º 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.
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.
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.

*permeability of partially filled compartments shall be consistent with the amount of liquid carried in the compartment. Whenever damage penetrates a tank containing liquids, it shall be assumed that the contents are completely lost from that compartment and replaced by salt water up to the level of the final plane of equilibrium.
