PRESTRESSED CONCRETE FLOATING STRUCTURES (STATE OF THE ART)

Although Portland cement concrete has been successfully employed for structures in an aqueous environment, its potential for floating structures has only recently received serious attention. During two national emergencies, a substantial effort was organized for reinforced concrete ship construction. During the period 1918-1920, a number of steamships were built and documented. Some saw considerable service and gave a good account of themselves in rough weather. History repeated itself 20 years later, when a fleet of 24 concrete steamships and 60 concrete barges were constructed. Again, at war's end, the concrete fleet was retired, and eventually disposed of as surplus. Recent activity in offshore construction has opened new opportunities for floating and sumbersible concrete structures, as evidenced by the large oil production facilities for the North Sea. A floating platform for liquid perroleum gas production is now under construction in Tacoma, Washington. This vessel, with a full load displacement of 68,000 tons, is destined for service in the Java Sea.
