is increasing as faster, larger and more efficient ships are designed, built
and employed. The total volume of world seaborne trade has increased over
the last 50 years due to several reasons. Firstly, discovery of new sources
of raw materials around the globe, as well as development of new sources
of demand as economies grow, have changed the international trade pat-
tern and increased the volume of sea transportation. Second, advances in
ship design and shipbuilding which led to the construction of larger vessels
for cost-effective transportation and, consequently, growth in international
seaborne trade. Third, liberalisation in international trade which allowed
companies not only to outsource their raw material and labour force, but
also to spread their operations to more cost-effective locations, and to trans-
port their finished products to the end-users’ market, has also been an
important factor in the growth in sea transportation. Finally, overall world
economic growth, improvement in economic conditions and changes in
people’s lifestyles have also contributed to the increase in demand for man-
ufactured products and goods which, in turn, requires transportation of raw
materials.
For the purpose of shipping operations, market analysis and research, the
international seaborne trade can be broadly classified into: liquid bulk; dry
bulk; general cargo; and unitised transportation or container trade. There are
also several other types of cargoes, such as natural gas, refrigerated cargoes,
automobiles, forest products and livestock, which require special types of
ships for transportation. Figure 2.1 illustrates the evolution of the interna-
tional seaborne trade in major dry and liquid-bulk commodities, as well as
