5.33 A review of electrical services on board
can reveal the potential for unexpected efficiency gains. However
care should be taken to avoid the creation of new safety hazards when
turning off electrical services (e.g. lighting). Thermal insulation
is an obvious means of saving energy. Also see comment below on shore
power.
5.34 Optimization of reefer container stowage
locations may be beneficial in reducing the effect of heat transfer
from compressor units. This might be combined as appropriate with
cargo tank heating, ventilation, etc. The use of water-cooled reefer
plant with lower energy consumption might also be considered.
