ABSTRACT (Continue on reveree elde 11 neceeeery and Identify by block number) 



Of the many foreseeable problems confronting economical ocean thermal 

 energy conversion operation, two major items are the deterioration of the 

 structural and functional components, which prevents efficient operation, 

 and the biofouling of the surfaces, which adds excess weight to the floating 

 ocean platform. The techniques required for effective long-term control of 

 deterioration and corrosion have been investigated actively for many years,
