12.2.1 Where
cargoes are to be loaded or carried at temperatures above 80°C,
temperature distribution investigations and thermal stress calculations
are to be submitted. These are to be carried out using the highest
cargo temperature during any part of the voyage, including loading
and unloading.
12.2.2 The
calculations are to give the resultant stresses on the hull structure,
based on a sea temperature of 0°C and an air temperature of 5°C.
Any proposals for reinforcement of the hull structure and/or limitation
of the still water bending moment for heated cargo conditions are
to be submitted.
12.2.3 Submitted
proposals are to take account of non-uniform loading patterns with
resultant variations in temperature distribution, where applicable.
