(2), (3) and (4) of this Regulation to provide a measure of
protection against oil outflow in the event of grounding or
collision.

2. Segregated ballast tanks and spaces other than oil tanks
within the cargo tank length (Lt) shall be so arranged as to
comply with the following requirement:

*

PAc + PAs J[LT + 2D)]

where:

PAc = the side shell area in square metres for each segregated
ballast tank or space other than an oil tank based on projected
moulded dimensions,

PAs = the bottom shell area in square metres for each such tank
or space based on projected moulded dimensions,

Lt = length in metres between the forward and after extremities
of the cargo tanks,

B = maximum breadth of the ship in metres as defined in
Regulation 1(21) of this Annex,

D = moulded depth in metres measured vertically from the top of
the keel to the top of the freeboard deck beam at side
amidships. In ships having rounded gunwales, the moulded depth
shall be measured to the point of intersection of the moulded
lines of the deck and side shell plating, the lines extending as
though the gunwale were of angular design,

J = 0.45 for oil tankers of 20,000 tons deadweight 0.03 for oil
tankers of 200,000 tons deadweight and above, subject to the
provisions of paragraph (3) of this Regulation.

For intermediate values of deadweight the value of J shall be
determined by linear interpolation.

Whenever symbols given in this paragraph appear in this
Regulation, they have the meaning as defined in this paragraph.

3. For tankers of 200,000 tons deadweight and above the value of
J may be reduced as follows:

J reduced = [J - (a - Oc + Os)] or 0.24 Oa (?) whichever is
greater where:

a = 0.25 for oil tankers of 200,000 tons deadweight

a = 0.40 for oil tankers of 300,000 tons deadweight

a = 0.50 for oil tankers of 420,000 tons deadweight and above,

For intermediate values of deadweight the a shall be determined
by linear interpolation.

Oc = as defined in Regulation 23(1)(a) of this Annex,

Os = as defined in Regulation 23(1)(b) of this Annex,

Oa = the allowable oil outflow as required by Regulation 24(2)
of this Annex.

4. In the determination of PAc and PAs for segregated ballast
tanks and spaces and other than oil tanks the following shall
apply:

a) the minimum width of each wing tank or space either of which
extends for the full depth of the ship's side or from the deck
to the top of the double bottom shall be not less than 2 metres.
The width shall be measured inboard from the ship's side at
right angles to the centre line. Where a lesser width is
provided the wing tank or space shall not be taken into account
when calculating the protecting area PAc; and

b) the minimum vertical depth of each double bottom tank or
space shall be B/15 or 2 metres, whichever is the lesser. Where
a lesser depth is provided the bottom tank or space shall not be
taken into account when calculating the protecting area PAs.

The minimum width and depth of wing tanks and double bottom
tanks shall be measured clear of the bilge area and, in the case
of minimum width, shall be measured clear of any rounded gunwale
area.

PUMPING, PIPING AND DISCHARGE ARRANGEMENTS OF OIL TANKERS

Paragraphs (1) to (4) _ No change

The following paragraphs are added to the existing text:

5. Every new oil tanker required to be provided with segregated
ballast tanks, or fitted with a crude oil washing system shall
comply with the following requirements:

a) it shall be equipped with oil piping so designed and
installed such that oil retention in the lines is minimized; and

b) means shall be provided to drain all cargo pumps and all oil
lines at the completion of cargo discharge, where necessary by
connexion to a striping device. The line and pump drainings
shall be capable of being discharged both ashore and to a cargo
tank or a slop tank. For discharge ashore a special small
diameter line shall be provided for that purpose and connected
outboard of the ship's manifold valves.

6. Every existing crude carrier required to be provided with
segregated ballast tanks, or fitted with a crude oil washing
system or operated with dedicated clean ballast tanks, shall
comply with the provisions of paragraph (5)(b) of this
Regulation.
