An Investigation: U. S. Import Dependence for Mineral Resources, 'Super'Bulk Carriers,and Deepwater Port Development.

摘要

The thesis examines the increasing dependence of the United States on foreign sources of major fuel and non-fuel mineral resources which appear to have potential requirements for deepwater ports and terminals. Major oceanborne bulk commodity import projections for crude petroleum,iron ore,bauxite,and alumina are presented. Principal bulk commodity ports are identified and major commodity movements are discussed. Past and possible future trends in the construction of large ocean bulk carriers are reviewed. Construction and transportation economies available via 'super'bulk carriers are examined with emphasis on 'super'tankers. The primary consequences of a failure to provide United States facilities to accommodate 'super'bulk carriers are identified and recent events in U.S. development of deepwater ports are presented. The major conclusion is that the United States,if it is to maintain its status as a leading economic power,should utilize the technological efficiency provided by 'super'bulk carriers. (Author)
