6.1 Replace by the following:
Tankage to be crude oil washed
6.1.1 Before departure on a ballast voyage:
(a) Approximately one quarter of the cargo tanks
shall be crude oil washed for sludge control purposes on a rotational
basis and in accordance with the procedures specified in the Operations
and Equipment Manual. However, for these purposes, no tank need be
crude oil washed more than once in every four months; and
(b) If it is considered that additional ballast
in a cargo tank or tanks may be required during the ballast voyage
under the conditions and provisions specified in Regulation 13(3) of Annex I of MARPOL
73/78, the tank or tanks which may be used for this ballast
shall be crude oil washed in accordance with the procedures specified
in the Operations and Equipment Manual.
6.1.2 Ballast water shall not be put into cargo
tanks that have not been crude oil washed. Water that is put into
a tank which has been crude oil washed but not water rinsed shall
be regarded as dirty ballast.
6.1.3 Crude oil washing shall not be conducted
between the final discharge and loading ports; that is to say, no
crude oil washing shall be undertaken during the ballast voyage.
6.3 Replace by the following:
Ballasting of cargo tanks
Care shall be taken at the completion of crude oil washing
of any cargo tank that might contain ballast to strip the tank as
completely as possible. Where this ballast is filled through cargo
lines and pumps, these must be drained and stripped of oil using the
means required by 4.4.5.
6.4 The last two sentences are not applicable.
6.5 Replace by the following:
Discharge of oily water effluents on
The discharge of additional ballast from cargo tanks and
any other water effluent discharged during the ballast voyage shall

6.8 This paragraph is not applicable.
7(d) Replace by the following:
7(d) Details of the requirements of section 6 of these Specifications together with
advice and instructions, where appropriate, in meeting these requirements
(i) Recommended methods and programmes of crude
oil washing in order to accord with all foreseeable circumstances
of cargo discharge restraints and to obtain maximum trim during the
completion of washing and draining of each tank.
(ii) The method of draining tanks which shall
include information on optimum trim conditions as required by 4.4.10.
(iii) The method of draining cargo pumps, cargo
lines, crude oil washing lines and stripping lines, and spaces into
which they may be drained, together with the final discharge ashore
via the small discharge line on completion of discharge.
(iv) Typical washing programmes under various
conditions of loading specifying:
(1) The tanks to be washed in accordance with 6.1;
(2) The method for washing each tank, that is,
single- or multi-stage;
(3) The number of tank washing machines to be
(4) The duration of the crude oil wash and water
rinse where the latter is appropriate.
(v) The procedure for verifying by sound patterns
that bottom mounted machines are operating shall be carried out towards
the end of the wash cycle for each tank. When carrying out such verification
all other machines shall be shut down if necessary.
