Thickness measurement on deck should be carried out according
to paragraph 3 of these guidelines i.e. in every other deck longitudinal
for three transverse sections, within the cargo area, as given in
Table 7.3.3, paragraph 1.2, of the Condition Assessment Scheme (resolution MEPC.94(46), as amended). For
areas in tanks where environmental conditions seem to be similar,
the extent of this thickness measurement may be specially considered
by the attending surveyor.
