0. ABSTRACT (Continue on reverse side If necessary and identify by bIoci< number) 



A propellant-actuated anchor (CEL 20K) has been designed to function in seafloors 

 from soft clay to competent basalt, yielding a minimum long-term hodling capacity of 

 20,000 pounds in water depths of 50 to 20,000 feet. Thirty -six individual tests of the anchor 

 are described in detail, demonstrating that the anchor functions satisfactorily in a wide variety 

 of situations. Generalized and specific applications are given along with alternative installa- 

 tion and recovery schemes for the anchor.
