STOWAGE OF BULK GRAIN

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 B6, grant dispensation from trimming in those cases where the under-deck 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 A2.7, 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 a 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 A16. Alternatively, in "partly filled compartments", the bulk grain surface may be secured by strapping or lashing as described in A17 or A18.

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 divisions is grain-tight;

.2 the construction meets the requirements of A11, A12 and A13; 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 B2.8.2, Note (2), B2.9.2, Note (3), or B5.2, as applicable.
