wholly submerged several hundred feet with only an access tower to the

surface. The design and construction of such novel structures will 



require imagination and utilization of past experiences drawn from many 

 engineering disciplines. 



This report discusses only the topic of concrete. The main platform, 

 the cold water intake pipe, and the anchor for OTEC structures could be 

 built of concrete today using available technology and construction 

 practices; however, further study at this time of selected problems with 

 reachable near-term solutions can significantly lower costs, lessen 

 risks, and provide longer structure life.
