5.1 In “filled compartments" and in “filled
compartments, untrimmed", all graintight longitudinal members either
permanent or temporary may be considered as effective over their full
depth for the purpose of limiting the transverse shift of grain. If
such a member is discontinuous longitudinally, it should be considered
effective over its actual length.
5.2 The division referred to in regulation
5(c) should be understood to mean a temporary construction
which is installed for the express purpose of reducing the grain heeling
moment by limiting the transverse shift of grain and, as such, it
should comply with the dimensional parameters described in that regulation
in order to be considered effective. With respect to permanent longitudinal
structures, such as girders, partial bulkheads, etc., whether on the
centreline or not, these may be considered as effective for their
full depth for the purpose of preparing the volumetric heeling moment
curves for partly filled compartments.
