材料：

Every new crude oil tanker of 20000 tons deadweight and above shall be fitted with a cargo tank cleaning system using crude oil washing．The Administration shall undertake to ensure that the system fully complies with the requirements of MARPOL within one year after the tanker was first engaged in the trade of carrying crude oil or by the end of the third voyage carrying crude oil suitable for crude oil washing，whichever occurs later．Unless such oil tanker carries crude oil which is not suitable for crude oil washing，the oil tanker shall operate the system in accordance with the requirements of that Regulation．

Every existing crude oil tanker of 40000 tons deadweight and above shall be provided with segregated ballast tanks．Existing crude oil tankers may，in lieu of being provided with segregated ballast tanks，operate with a cargo tank cleaning procedure using crude oil washing unless the crude oil tanker is intended to carry crude oil which is not suitable for crude oil washing．

Existing crude oil tankers may，in lieu of being provided with segregated ballast tanks or operating with a cargo tank cleaning procedure using crude oil washing，operate with dedicated clean ballast tanks in accordance with the provision of Regulation 13A of this Annex for the following period：for crude oil tankers of 70 000 tons deadweight and above，until two years after the date of entry into force of the present Convention；and for crude oil tankers of 40000 tons deadweight and above but below 70 000 tons deadweight，until four years after the date of entry into force of the present Convention．

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．
