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.

It can be concluded that ________.A.it is not necessary to do crude oil washing prior to ballast voyage
B.taking into account the tanker's trading pattern and expected weather conditions,it is sometimes necessary to do crude oil washing after each ballast voyage
C.if it is possible ballast water shall always be put into cargo tanks prior to commencing their crude oil washing operations
D.sufficient cargo tanks shall be crude oil washed prior to each ballast voyage in order that the tanker could be kept properly ballasted without breaking any regulations in connection with ballasting of cargo tanks
