CONTAINER trades in established US and Canadian markets are expected to see further strong growth while Latin American and Caribbean markets will see huge increases in demand, predicts a British study. UK-based Ocean Shipping Consultants, in their latest market study, said although trade growth remained vulnerable to disruption at the macro-economic level, the most likely outlook from the current perspective suggested significant growth in each regional market. But, the study did differentiate between prospects for each significant port range. ''In North America, it is forecast that total demand will increase by some 89 per cent over recorded 1991 levels to reach a total of 31.3 million twenty-foot equivalent units (TEUs) in 2005,'' the report said. In 1991, there was a significant increase in port demand with an increase of some 42 per cent recorded to reach a total of 16.6 million TEUs in 1991, with a limited further increase identified for 1992. The study said when North America reached the forecast figures in 2005, the market share of ports on the Atlantic coast would continue to decline. ''This will be reciprocated by strong demand growth in the south Atlantic and also in the Pacific north west,'' it said. ''Both of these markets are set to record sharp increases in market share.'' It added that in the central America / Caribbean markets, growth would be even more rapid with an increase in demand of some 151 per cent to 8.6 million TEUs forecast by 2005. The study identified the south American markets as the place with the strongest growth where overall demand was set to rise by some 165 per cent by 2005, with total demand placed at over four million TEUs in 2005. This would require considerable investment in port facilities if underlying demand was not to be constrained, it said. The study said port volumes in northern Atlantic and St Lawrence port had remained fairly constant at between 4.5-4.7 million TEUs per annum. But ports in the southern Atlantic seaboard recorded dynamic demand growth of around 101 per cent to reach a total of 2.53 million TEUs in 1991. The pace of expansion on the west coast has been significant and the southern ports demand has increased by around 64 per cent to reach a total of 5.4 million TEUs in 1991. The study pointed out that the unbroken run of expansion had been interrupted over 1991 and a limited fall in demand had since been recorded. ''This has been the direct result of the recession in the Californian economy together with strong competition from more northerly ports in the intermodal market,'' it said. The northern Pacific ports had recorded a dynamic overall development and currently account for in excess of 3.06 million TEU port moves, with this representing a rise of some 80 per cent in the period since 1984. The total development of Latin American and Caribbean container trades since 1984 equated to some 59 per cent, with total port demand running at some 4.97 million TEUs in 1991.
