  • 第2题：

    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．

    B.until four years after the date of entry into force of the present Convention

    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
