When calculating the average void depth (Vd) in accordance
with part B, section I(A), the boundary
distance in the corner of a compartment should be the distance from
the hatch end beam or from the hatch side girder to the boundary of
the compartment, whichever is the greater. The girder depth (d) should
be taken to be the depth of the hatch end beam or the depth of the
hatch side girder, whichever is the least.
