Concrete marine structures: A state-of-the-art review

Abstract

The state-of-the-art as well as the development of both floating and fixed concrete marine structures for the period 1985–88 are reviewed. Relevant structural applications and the operational performance of previously built structures are considered. Present design principles are examined and trends in structural analysis pointed out, the latter being oriented towards probabilistic approaches while requesting the most appropriate reliability levels with respect to various loading conditions as applicable to various structural elements and to the general stability of the structures. Recent developments in construction techniques, and in delivery and deployment methods, are also reported. Various national and international research projects either ongoing or completed during the period in question are briefly reviewed. The satisfactory performance and durability of concrete structures in the marine environment are examined. Progress in materials technology is reported, being focused on the significant deadweight/displacement ratio reduction available to floating concrete structures. Finally, the low investment and maintenance costs of concrete marine structures is pointed out.
