ANNEX
AMENDMENTS TO ANNEX I OF MARPOL 73/78
Regulation 1
Definitions The following new paragraph (8)(c) is inserted after the existing
paragraph(8)(b): "(c) Notwithstanding the provisions of subparagraph (a) of
this paragraph, conversion of an existing oil tanker to meet the requirements
of regulation 13F or 13G of this Annex shall not be deemed to constitute a
major conversion for the purpose of this Annex." New regulations 13F and 13G
The following new regulations 13F and 13G are inserted after the existing
regulation 13E:
REGULATION 13F OF ANNEX I OF MARPOL 73/78 Prevention of oil pollution in the
event of collision or stranding (1) This regulation shall apply to oil tankers
of 600 tons deadweight and above: (a) for which the building contract is
placed on or after 6 July 1993, or (b) in the absence of a building contract,
the keels of which are laid or which are at a similar stage of construction on
or after 6 January 1994, or (c) the delivery of which is on or after 6 July
1996, or (d) which have undergone a major conversion: (i) for which the
contract is placed after 6 July 1993; or (ii) in the absence of a contract,
the construction work of which is begun after 6 January 1994; or (iii) which
is completed after 6 July 1996. (2) Every oil tanker of 5,000 tons deadweight
and above shall: (a) in lieu of regulation 13E, as applicable, comply with the
requirements of paragraph (3) unless it is subject to the provisions of
paragraphs (4) and (5); and (b) comply, if applicable, with the requirements
of paragraph (6). (3) The entire cargo tank length shall be protected by
ballast tanks or spaces other than cargo and fuel oil tanks as follows: (a)
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 rights angles to the side shell, as specified
below: w = 0.5 + DW (m) or
20,000 w = 2.0 m, which is the lesser. The minimum value of w = 1.0 m. (b)
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. (c) Turn of the bilge area or at locations without
a clearly defined turn of the bilge When the distance h and w are different,
the distance w shall have preference at levels exceeding 1.5 h above the
baseline as shown in figure 1. (d) The aggregate capacity of ballast tanks On
crude oil tankers of 20,000 tons deadweight and above and product carriers of
30,000 tons deadweight and above, the aggregate capacity of wing tanks, double
bottom tanks, forepeak tanks and afterpeak tanks shall not be less than the
capacity of segregated ballast tanks necessary to meet the requirements of
regulation 13. Wing tanks or spaces and double bottom tanks used to meet the
requirements of regulation 13 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. (e) 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 such wells are as small as practicable
and the distance between the well bottom and bottom shell plating is not less
than 0.5 h. (f) 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. (4) (a)
Double bottom tanks or spaces as required by paragraph (3)(b) 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: f . hc . pc . g + 100*p <-= dn ps g
 where: hc =
height of cargo in contact with the bottom shell plating in metres pc =
maximum cargo density in t/m3 dn = minimum operating draught under any
expected loading condition in metres ps = density of sea water in t/m3

*p = maximum set pressure of pressure/vacuum valve provided for the cargo tank
in bars f = safety factor = 1.1 g = standard acceleration of gravity (9.81
m/s2). (b) Any horizontal partition necessary to fulfil the above requirements
shall be located at a height of not less than B/6 or 6 metres, whichever is
the lesser, but not more than 0.6D, above the baseline where D is the moulded
depth amidships. (c) The location of wing tanks or spaces shall be as defined
in paragraph (3)(a) except that, below a level 1.5 h above the baseline where
h is as defined in paragraph (3)(b), the cargo tank boundary line may be
vertical down to the bottom plating, as shown in figure 2. (5) Other methods
of design and construction of oil tankers may also be accepted as alternatives
to the requirements prescribed in paragraph (3), provided that such methods
ensure at least the same level of protection against oil pollution in the
event of collision or standing and are approved in principle by the Marine
Environment Protection Committee based on guidelines developed by the
Organization. (6) For oil tankers of 20,000 tons deadweight and above the
damage assumptions prescribed in regulation 25(2)(b) shall be supplemented by
the following assumed bottom raking damage: (a) longitudinal extent: (i) ships
of 75,000 tons deadweight and above: 0.6 L measured from the forward
perpendicular (ii) ships of less than 75,000 tons deadweight: 0.4 L measure
from the forward perpendicular (b) transverse extent: B/3 anywhere in the
bottom (c) vertical extent: breach of the outer hull. (7) Oil tankers of less
than 5,000 tons deadweight shall: (a) at least be fitted with double bottom
tanks or spaces having such a depth that the distance h specified in paragraph
(3)(b) 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 mid-ship flat bottom as shown in figure 3; and (b) 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)(a) complying with the following: w = 0.4 + 2.4 DW (m)
20,000 with a minimum value of w = 0.76 m. (8) 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 of 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. (9) 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.
