材料：

Every new crude oil tanker of 20000 tons deadweight and above and every new product carrier of 30000 tons deadweight and above shall be provided with segregated ballast tanks．The capacity of the segregated ballast tanks shall be so determined that the ship may operate safely on ballast voyages without recourse to the use of cargo tanks for water ballast．

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）meters（without taking into account any ship&39;s deformation）shall not be less than dm = 2.0 + 0.02L；

（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 association with the trim by the stern of not greater than 0.015L；

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．

In no case shall ballast water be carried in cargo 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，or，in exceptional cases where the particular character of the operation of an oil tanker renders it necessary to carry ballast water in excess of the quantity required，provided that such operation of the oil tanker falls under the category of exceptional cases as established by the Organization．
