Section 4 in The Merchant Shipping (Equivalent Arrangements For Carriage Of Grain) Order, 1977
4. (a) In both "filled" and "partly filled" compartments, longitudinal divisions may be provided as a device either to refuse the adverse heeling effect of grain shift or to limit the depth of cargo used for securing the cain surface. Such divisions should be fitted grain-tight and constructed accordance with the provisions of part I of Schedule II.
(b)In a "filled" compartment a division, if fitted, should extent downwards from the underside of the deck or hatch covers to a distance below the deck line of at least one-eight of the maximum breadth of the compartment. Except in the case of oil seeds, a longitudinal division beneath of hatchway may be replaced by a saucer of bagged grain or other suitable cargo, such a saucer should be formed in the manner described in Part I of Schedule H.(c)In a "partly filled" compartment, a division, if fitted should extend from one-eight of the maximum breadth of the compartment above the level of the grain surface and to the same distance below the grain surface. When used to limit the depth of the cargo used for securing the height of the centreline division should be not less than 0.61 metres above the grain surface.(d)Furthermore, the adverse heeling effects of grain shift may be reduced by tightly stowing the wings and ends of a compartment with bagged grain or other suitable cargo adequately restrained from shifting.Securing :
