Recommendation for Development 



It is recommended that research and development be monitored to assess 

 antifouling coatings of longer service life presently under development. 

 These coatings may contain mixtures of antifoulant materials, but must be 

 noncorrosive to aluminum if aluminum is selected for the heat-exchanger 

 tubes. These coatings may be thick and may require special attention, such 

 as periodic underwater maintenance. Environmental problems must be 

 weighed. The complete antifouling system must be designed with redundancy 

 to assure efficient operation for the OTEC plant. Since the warm water
