ports and are thus prone to the use of economies of scale by
maritime shipping companies. These two ports are serviced by an array of
ship classes, giving a sample of rates per TEU per ship class (see
above). The introduction of
the Emma class of 12,000 TEU containerships in 2008 marginally
improved the shipping rates. The potential introduction of a
"Malacca Max" class of 18,000 TEU containerships would further
reduce rates per TEU but would impose higher port equipment costs,
such as cranes able to handle such ships. There is thus a balance
between the benefits that maritime shipping companies derive from
economies of scale and the additional capital investment this
process imposes on port terminals.
