15.1.1
Filling limit (FL) means the
maximum liquid volume in a cargo tank relative to the total tank volume
when the liquid cargo has reached the reference temperature.
15.1.2
Loading limit (LL) means the
maximum allowable liquid volume relative to the tank volume to which
the tank may be loaded.
15.1.3
Reference temperature means
(for the purposes of this chapter only):
-
.1 when no cargo vapour pressure/temperature control,
as referred to in chapter 7, is provided, the temperature corresponding
to the vapour pressure of the cargo at the set pressure of the PRVs;
and
-
.2 when a cargo vapour pressure/temperature control,
as referred to in chapter 7, is provided, the temperature of the cargo
upon termination of loading, during transport or at unloading, whichever
is the greatest.
15.1.4
Ambient design temperature for unrestricted
service means sea temperature of 32°C and air temperature
of 45°C. However, lesser values of these temperatures may be accepted
by the Administration for ships operating in restricted areas or on
voyages of restricted duration, and account may be taken in such cases
of any insulation of the tanks. Conversely, higher values of these
temperatures may be required for ships permanently operating in areas
of high-ambient temperature.
