When carrying cargoes at low temperatures:
-
.1 the cooldown procedure laid down for that particular
tank, piping and ancillary equipment shall be followed closely;
-
.2 loading shall be carried out in such a manner
as to ensure that design temperature gradients are not exceeded in
any cargo tank, piping or other ancillary equipment; and
-
.3 if provided, the heating arrangements associated
with the cargo containment systems shall be operated in such a manner
as to ensure that the temperature of the hull structure does not fall
below that for which the material is designed.
