and successful solutions for most situations have been developed. For the 

 most part, these solutions can be directly transferred to the ocean 

 thermal energy conversion plant. The majority, of problems in these areas 

 are expected to be associated with scale-up and will require some advanced 

 development due to the immensity of the ocean thermal energy conversion 

 platform. 



Current antifouling control systems are not effective for long-term 

 fouling prevention. Commercially available antifouling coatings are 

 limited to a 3-year service life in temperate waters , and even shorter in 

 tropical waters. However, underwater cleaning techniques and some fouling- 

 control systems presently being used by conventional power plants may find 

 utility on an ocean thermal energy conversion plant. In addition, some 

 recent major advances in long-term antifouling coatings sponsored by the 

 Navy may be applicable to ocean thermal energy conversion.
