     Regulation 13D
     EXISTING OIL TANKERS HAVING SPECIAL BALLAST ARRANGEMENTS
     1. Where an existing oil tanker is so constructed or operates in such a manner that it complies at all times with the draught and trim requirements set out in Regulation 13(2) of this Annex without recourse to the use of ballast water, it shall be deemed to comply with the segregated ballast tank requirements referred to in Regulation 13(7) of this Annex, provided that all of the following conditions are complied with:
     a) operational procedures and ballast arrangements are approved by the Administration;
     b) agreement is reached between the Administration and the Governments of the Port States Parties to the present Protocol concerned when the draught and trim requirements are achieved through an operational procedure; and
     c) the International Oil Pollution Prevention Certificate is endorsed to the effect that the oil tanker is operating with special ballast arrangements.
     2. In no case shall ballast water be carried in oil tanks except 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. Such additional ballast water shall be processed and discharged in compliance with Regulation 9 of this Annex and in accordance with the requirements of Regulation 15 of this Annex, and entry shall be made in the Oil Record Book referred to in Regulation 20 of this Annex.
     3. An Administration which has endorsed a Certificate in accordance with sub-paragraph (1)(c) of this Regulation shall communicate to the Organization the particulars thereof for circulation to the Parties to the present Protocol.
     Regulation 13E
     PROTECTIVE LOCATION OF SEGREGATED BALLAST SPACES
     1. In every new crude oil tanker of 20,000 tons deadweight and above and every new product carrier of 30,000 tons deadweight and above, the segregated ballast tanks required to provide the capacity to comply with the requirements of Regulation 13 of this Annex which are located within the cargo tank length, shall be arranged in accordance with the requirements of paragraphs (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.
