6. The CEL 100K Propellant Anchor System with the present configura- 

 tion of sediment fluke can be used to install embedment anchors having 

 holding capacities in excess of 150,000 pounds (670 kN) applied in any 

 direction. Although ultimate capacities were not determined, long-term 

 capacities were estimated to be on the same order as that of the 1-3/4- 

 inch (44 mm) wire rope used as the main anchor load line (approximately 

 200,000 pounds, or 890 kN) . 



7. Expending the piston, rather than retrieving it, appears to be 

 the more cost-effective alternative in most applications. However, the 

 proper keying of the fluke in soft sediments when the piston is not 

 retrieved remains to be demonstrated. 



8. The present launch vehicle is durable and reliable, as evidenced 

 by its present excellent condition after nineteen installations. Although 

 not subject to accurate prediction, its remaining useful life is estimated 

 to be well in excess of usage to date. 



9. Except as noted in the Appendix, the procedures used and refined 

 during the reported installation appear to be optimum for the system and 

 should be used in future applications. Included especially are the 

 procedures used for system assembly, crane handling, faking of the load 

 line, checking of the S/A device, and firing. 



10. Considerable experience with, and knowledge of, the components 

 are required for the successful utilization of the anchor system in its 

 present configuration. This necessitates the availability of CEL techni- 

 cal support. The proposed development of a standardized service- 

 approved anchor and installation method for Navy operating forces would 

 overcome this necessity.
