10.1 All necessary and reasonable trimming shall
be performed to level all free grain surfaces and to minimize the
effect of grain shifting.
10.2 In any filled compartment, trimmed, the bulk
grain shall be trimmed so as to fill all spaces under the decks and
hatch covers to the maximum extent possible.
10.3 In any filled compartment, untrimmed, the
bulk grain shall be filled to the maximum extent possible in way of
the hatch opening but may be at its natural angle of repose outside
the periphery of the hatch opening. A filled compartment may qualify
for this classification if it falls into one of the following categories:
-
.1 the Administration issuing the document of
authorization may, under B 6, grant
dispensation from trimming in those cases where the underdeck void
geometry resulting from free flowing grain into a compartment, which
may be provided with feeder ducts, perforated decks or other similar
means, is taken into account when calculating the void depths; or
-
.2 the compartment is "specially suitable" as
defined in A 2.7, in which case
dispensation may be granted from trimming the ends of that compartment.
10.4 If there is no bulk grain or other cargo
above a lower cargo space containing grain, the hatch covers shall
be secured in an approved manner having regard to the mass and permanent
arrangements provided for securing such covers.
10.5 When bulk grain is stowed on top of closed
'tween-deck hatch covers which are not grain-tight, such covers shall
be made grain-tight by taping the joints, covering the entire hatchway
with tarpaulins or separation cloths, or other suitable means.
10.6 After loading, all free grain surfaces in
partly filled compartments shall be level.
10.7 Unless account is taken of the adverse heeling
effect due to the grain shift according to this Code, the surface
of the bulk grain in any partly filled compartment shall be secured
so as to prevent a grain shift by overstowing as described in A 16. Alternatively, in partly filled
compartments, the bulk grain surface may be secured by strapping or
lashing as described in A 17 or A 18.
10.8 Lower cargo spaces and 'tween-deck spaces
in way thereof may be loaded as one compartment provided that, in
calculating transverse heeling moments, proper account is taken of
the flow of grain into the lower spaces.
10.9 In filled compartments, trimmed; filled compartments,
untrimmed; and partly filled compartments, longitudinal divisions
may be installed as a device to reduce the adverse heeling effect
of grain shift provided that:
-
.1 the division is grain-tight;
-
.2 the construction meets the requirements of A 11, A 12 and A 13; and
-
.3 in 'tween-decks the division extends from deck
to deck and in other cargo spaces the division extends downwards from
the underside of the deck or hatch covers, as described in B 2.8.2, note (2); B 2.9.2, note (3); or B 5.2, as applicable.
