REGULATION 13 



Segregated Ballast Oil Tankers 



(1) Every new oi] tanker of 70,000 tons deadweight and above shall 

 be provided with segregated ballast tanks and shall comply with the 

 requirements of this Regulation. 



(2) The capacity of the segregated ballast tanks shall be so deter- 

 mined that the ship may operate safely on ballast voyages without 

 recourse to the use of oil tanks for water ballast except as provided 

 for in paragraph (3) 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 each of the following requirements : 



(a) the moulded draught amidships (dm) in metres (without 

 taking into account any ship's deformation) shall not be less than : 



dm = 2.0 + 0.02 L, 



(b) the draughts at the forward and after perpendiculars shall 

 correspond to those determined by the draught amidships (dm), 

 as specified in sub-paragraph (a) of this paragraph, in associa- 

 tion with the trim by the stern of not greater than 0.015 L, and 



(c) 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). 



(3) In no case shall ballast water be carried in oil tanks except in 

 weather conditions so severe that, in the opinion of the Master, it is 

 necessary to carry additional ballast water in oil tanks for the safety 

 of the ship. Such additional ballast water shall be processed and dis- 

 charged in compliance with Regulation 9 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. 



(4) Any oil tanker which is not required to be provided with segre- 

 gated ballast tanks in accordance with paragraph (1) of this Regula- 

 tion may, however, be qualified as a segregated baUast tanker, pro- 

 vided that in the case of an oil tanker of 150 metres in length and 

 above it fully complies with the requirements of paragraphs (2) and 

 (3) of this Regulation and in the case of an oil tanker of less than 

 150 metres in length the segregated ballast conditions shall be to the 

 satisfaction of the Administration. 



REGULATION 1 4 



Segregation of Oil and Water Ballast 



(1) Except as provided in paragraph (2) of this Regulation, in 

 new ships of 4,000 tons gross tonnage and above other than oil tankers, 

 and in new oil tankers of 150 tons gross tonnage and above, no ballast 

 water shall be carried in any oil fuel tank.
