20 ABSTRACT (Continue on reverse side It necessary and identity by block number) 



The purpose of this study was to assess the state of the art of concrete technology 

 and construction practices as they are related to the construction of massive floating 

 structures to house ocean thermal energy conversion (OTEC) systems. The relevant 

 capabilities and limitations of available concrete technology and construction practices 

 are described and deficient areas are identified. Recommendations for research and
