1.2.1 Details of the proposed system of cargo pressure/temperature control
are to be submitted for consideration.
The ambient temperatures for air and sea-water are to be taken at their
highest daily mean temperatures for the unit’s proposed area of operation based on
the 100 year average return period. The ambient temperatures are to be rounded up to
the nearest degree Celsius.
The ambient temperatures are not to be taken as less than 45°C for air
and 32°C for sea-water unless agreed by LR.
The overall capacity of the system shall be such that it can control the
pressure within the design conditions without venting to atmosphere.
1.2.2 The system is to be tested at entry into service to prove its capability
to maintain the class notation temperature and pressure.
