C.within one year after the tanker was first engaged in the trade of carrying crude oil

D.by the end of the third voyage carrying crude oil

It is inferred that ________．A.all oil tankers，both the newly built and existing ones，shall be fitted with a cargo tank cleaning system using crude oil washing

B.a new crude oil tanker of 20 000 tons deadweight and above may，in lieu of being provided with crude oil washing system，operate with segregated ballast tanks

C.a new crude oil tanker of 20 000 tons deadweight and above may，in lieu of being provided with crude oil washing system，operate with dedicated clean ballast tanks

D.a new crude oil tanker of 20 000 tons deadweight and above shall not be fitted with a cargo tank cleaning system using crude oil washing immediately after her entry in the trade of carrying crude oil

材料：

The crude oil washing installation and associated equipment and arrangements shall comply with the requirements established by the Administration．

Such requirements shall contain at least all the provisions of Specifications for the Design，Operation and Control of Crude Oil Washing Systems adopted by the International Conference on Tanker Safety and Pollution Prevention，1978，in Resolution 15 and as may be revised by the Organization．

An inert gas system shall be provided in every cargo tank and slop tank in accordance with the appropriate Resolutions of Chapter II-2 of SOLAS．

With respect to the ballasting of cargo tanks，sufficient cargo tanks shall be crude oil washed prior to each ballast voyage in order that，taking into account the tanker&39;s trading pattern and expected weather conditions，ballast water is put only into cargo tanks which have been crude oil washed. Every oil tanker operating with crude oil washing systems shall be provided with an Operations and Equipment Manual detailing the system and equipment and specifying operational procedures．Such a Manual shall be to the satisfaction of the Administration and shall contain all the information set out in the Specifications referred to in this Regulation．If an alteration affecting the crude oil washing system is made，the Operations and Equipment Manual shall be revised accordingly．

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．
