13.1 The minimum trim conditions and the parameters
of the stripping operations are to be as stated in the Operations
and Equipment Manual.
13.2 All tanks which have been crude oil washed
are to be stripped. The adequacy of the stripping is to be checked
by hand dipping at least in the aftermost hand dipping location in
each tank or by such other means as are provided and described in
the Manual. It should be ascertained that the adequacy of stripping
has been checked or will be checked before the ship leaves its final
port of discharge.
