(7) In such special circumstances as the Minister may determine a new IOPP Certificate need not be dated from the date of expiry of the existing IOPP Certificate as required by paragraph (2) (b), (5) or (6) of this Regulation. In these special circumstances, the new IOPP 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 5 of these Regulations, then:

( a ) the anniversary date shown on the IOPP 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;

( b ) the subsequent annual or intermediate survey required by Regulation 5 of these Regulations shall be completed at the intervals prescribed by that Regulation using the new anniversary date;

( c ) 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 5 of these Regulations are not exceeded.

(9) An IOPP Certificate issued under Regulation 6 or 7 of these Regulations shall cease to be valid in any of the following cases:

( a ) if the relevant surveys are not completed within the periods specified under Regulation 5 (1) of these Regulations;

( b ) if the Certificate is not endorsed in accordance with Regulation 5 (1) (c) or 5 (1) (d) of these Regulations;

This capacity may be further reduced to 0.8 per cent where the tank washing arrangements are such that once the slop tank or tanks are charged with washing water, this water is sufficient for tank washing and, where applicable, for providing the driving fluid for eductors, without the introduction of additional water into the system.

New oil tankers of 70,000 tons deadweight and above 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 ) Every oil tanker shall be fitted with an oil discharge monitoring and control system, the design and installation of which is in compliance with the specification recommended by the Organisation and has been approved by the Minister. 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 10 (1) (a) of these Regulations. 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. The oil discharge monitoring and control system shall be designed and installed in compliance with the Guidelines and Specifications for Oil Discharge Monitoring and Control Systems for Oil Tankers developed by the Organisation and approved by the Minister;

( b ) effective oil/water interface detectors approved by the Minister 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 Minister. 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 10 of these Regulations.

(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 10 of these Regulations 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 10 of these Regulations are complied with.

(5) ( a ) The Minister 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 engaged exclusively in trades between ports or terminals within a Party. 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 Minister that facilities available to receive such oily mixtures are adequate.

( b ) The Minister may waive the requirements of paragraph (3) of this Regulation for oil tankers other than those referred to in subparagraph (a) of this paragraph in cases where:

(i) the tanker is an existing oil tanker of 40,000 tonnes deadweight or above, as referred to in Regulation 13 C (1) of these Regulations, engaged in specific trades, and the conditions specified in Regulation 13 C (2) are complied with; or

PART III Requirements for Minimising Oil Pollution from Oil Tankers due to Side and Bottom Damages

22 Damage assumptions.

22. (1) For the purpose of calculating hypothetical oil outflow from oil tankers, 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

( a ) side damage

(i) longitudinal extent (1c):

1/3 L2/3 or 14.5 metres, whichever is less

(ii) transverse extent (t c) (inboard from the ship's side at right angles to the centreline at the level corresponding to the assigned summer freeboard):

/images/si044y94p0054.gif or 11.5 metres, whichever is less.

(iii) vertical extent (Vc):

from the base line upwards without limit,

( b ) bottom damage

For 0.3L from the forward perpendicular of the ship

Any other part of the ship

(i) longitudinal extent (1s):

/images/si044y94p0055a.gif

or 5 metres, whichever is less

(ii) transverse extent (ts):

/images/si044y94p0055c.gif or 10 metres,

5 metres

whichever is less but not less than 5 metres

(iii) vertical extent from the base line (Vs):

/images/si044y94p0055d.gif or 6 metres, whichever is less.

(2) Wherever the symbols given in this Regulation appear in this Part, they have the meaning as defined in this Regulation.

23 Hypothetical outflow of oil.

23. (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 22 of these Regulations.

( a ) for side damages:

Oc = Σi + ΣKi Ci

(I)

( b ) for bottom damages:

Os = 1/3 (ΣZiWi + ΣZiCi

(II)

where:

Wi = volume of a wing tank in cubic metres assumed to be breached by the damage as specified in Regulation 22 of these Regulations; W1 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 22 of these Regulations; Ci for a segregated ballast tank may be taken equal to zero,

Ki

=

1 - /images/si044y94p0056a.gifwhen bi is equal to or greater than tc, Ki shall be taken equal to zero,

Zi

=

1 - /images/si044y94p0056b.gif 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 Part, 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 22 of these Regulations is located between wing oil tanks, Oc in formula (I) in paragraph (1) (a) of this Regulation 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 in this paragraph and taking for all other wing tanks involved in such a collision the value of the actual full volume.

/images/si044y94p0057.gif

where li = length in metres of void space or segregated ballast tank under consideration.

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

( b ) where the double bottom does not extend for the full length and width of the tank involved, the double bottom is considered non-existent and the volume of the tanks above the area of the bottom damage shall be included in formula (II) in paragraph (1) (b) of this Regulation even if the tank is not considered breached because of the installation of such a partial double bottom;

( c ) suction wells may be neglected in the determination of the value hi provided such wells are not excessive in area and extend below the tank for a minimum distance and in no case more than half the height of the double bottom. 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 the case where bottom damage simultaneously involves four centre tanks, the value of Os may be calculated according to the formula

Os = ¼ (Σi Wi + ΣZi Ci)      (III).

(5) The Minister 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) in paragraph (4) of this Regulation. The pipes for such suctions shall be installed at least at a height not less than the vertical extent of the bottom damage vs.

24 Limitation of size and arrangement of cargo tanks.

24. The owner of an oil tanker shall ensure that—

( a ) in case of the tanker is a new tanker, it complies with the provisions of this Regulation.

(ii) a tanker to which both the following conditions apply:

(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;

( b ) cargo tanks of oil tankers are of such size and arrangements that the hypothetical outflow Oc or Os calculated in accordance with the provisions of Regulation 23 of these Regulations 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;

( c ) the volume of any one wing cargo oil tank of an oil tanker does not exceed seventy-five per cent of the limits of the hypothetical oil outflow referred to in paragraph (b) of this Regulation; the volume of any one centre cargo oil tank does not exceed 50,000 cubic metres. However, in segregated ballast oil tankers as defined in Regulation 13 of these Regulations, 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;

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

(i) where no longitudinal bulkhead is provided inside the cargo tanks:

/images/si044y94p0059a.gif

but not to exceed 0.2L

(ii) where a centreline longitudinal bulkhead is provided inside the cargo tanks:

/images/si044y94p0059b.gif

(iii) where two or more longitudinal bulkheads are provided inside the cargo tanks:

(I) for wing cargo tanks: 0.2L

(II) for centre cargo tanks:

(A) If /images/si044y94p0059c.gif is equal to or greater than one-fifth: 0.2L

(B) if /images/si044y94p0060a.gif is less than one-fifth:

—where no centreline longitudinal bulkhead is provided:

/images/si044y94p0060b.gif

—where a centreline longitudinal bulkhead is provided:

/images/si044y94p0060c.gif

(iv) 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;

( e ) in order not to exceed the volume limits established by paragraphs (b), (c) and (d) 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 are provided for separating the tanks from each other and that those valves or devices are kept closed when the tanker is at sea; and

( f ) 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 are fitted with valves or similar closing devices at the point at which they open into any cargo tank and that those valves are 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.

25 Subdivision and stability.

25. (1) The owner of a new oil tanker shall ensure that it stability, complies 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 and that such damage is 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 or forward bulkhead bounding the machinery space located aft. The machinery space shall be treated as a single floodable compartment; and

( 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, the Minister may exempt the ship from compliance with the requirements concerned.

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:

( a ) side damage

( c ) if any damage of a lesser extent than the maximum extent of damage specified in subparagraphs (a) and (b) of this paragraph would result in a more severe condition, such damage shall be considered;

( d ) where the damage involving transverse bulkheads is envisaged as specified in 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 paragraph (1) (a) of this Regulation 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;

( e ) where the damage between adjacent transverse watertight bulkheads is envisaged as specified in 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 subparagraph (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;

( f ) 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 within the 20 degrees 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 (a) of this paragraph and other openings capable of being closed weathertight may be permitted;

( d ) the Minister shall be satisfied that the stability is sufficient during intermediate stages of flooding; and

( e ) equalisation 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 (a), (b) and (c) of this paragraph and sufficient residual stability shall be maintained during all stages where equalisation 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, configurations 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 assumed for spaces flooded as a result of damage shall be as follows:—

Spaces

Permeabilities

appropriated to stores

0.60

occupied by accommodation

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*;

*The 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.

( 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 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 Minister may require or allow the free surface corrections to be calculated at an angle of heel greater than 5 degrees for partially filled tanks; and

( 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 non-self-propelled oil tanker to which these Regulations apply shall be supplied by the owner 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 paragraph (1) (c) of this Regulation.

PART IV. Prevention of pollution arising from an oil pollution incident

26 Shipboard oil pollution emergency plan.

26. (1) The owner of an oil tanker of 150 tons gross tonnage and above and every ship other than an oil tanker of 400 tons gross tonnage and above shall ensure that there is carried on board a shipboard oil pollution emergency plan approved by the Minister. In the case of ships built before 4 April, 1993 this requirement shall apply 24 months after that date.

(2) Such a plan shall be in accordance with guidelines developed by the Organisation and written in the English language. The plan shall consist at least of:

the procedure to be followed by the master or other persons having charge of the ship to report an oil pollution incident based on the guidelines developed by the Organisation.

GIVEN under my Official Seal, this 18th day of February, 1994.

DAVID ANDREWS,

Minister for the Marine.

EXPLANATORY NOTE.

These Regulations give effect to Annex I of the International Convention for the Prevention of Pollution from Ships, adopted by the International Maritime Organisation on 2 November, 1973 and as amended by its Protocol adopted by the International Maritime Organisation on 17 February, 1978 and as further amended under resolutions adopted by the Marine Environment Protection Committee (MEPC) of the International Maritime Organisation.

The Regulations apply to all Irish ships wherever they may be and to all other ships when they are in the territorial waters of the State.

The Regulations prohibit and control discharge into the sea of oil and oily mixtures. The Regulations require ships to follow specified procedures when washing cargo tanks. Ballasting arrangements and the discharge of ballast water are also controlled. The Regulations also provide for adequate facilities at ports and terminals for the reception of oil and oily mixtures.

Ships are required to be surveyed for the purposes of the Regulations and to carry an International Pollution Prevention Certificate. Ships are also required to carry an Operations and Equipment Manual, an Oil Record Book and a shipboard oil pollution emergency plan approved by the Minister.

Section 29 of the Sea Pollution Act, 1991 provides for penalties for breaches of these Regulations.
