 tests indicate failure attributed to magnetic touchdown 

 assembly.

1. Reduced charge used (3.7 lb is max). 



2. Ship drifted from desired 600-foot site to 900-foot site 

 where soil was softer; a larger fluke would have been 

 appropriate.

2. Fim test with the 2-1/2 x 5-ft clay fluke. 



3. 17 kips measured, but actual load estimated to be much higher. 



4. Slack taken out of line before load cell hookup. Winch was 

 actually stalled by mistake; required a stalling load in excess 

 of 30 kips; load record indicated 10 kips additional for swell. 



5. No damage to equipment.

1. Reduced charge used (3.6 tb is max). 



2. Anchor loaded slowly to 36 kips; ship then reversed direction 

 and pulled the anchor out rapidly when the line became taut; 

 this was not the desired test method. 



3. No damage to equipment.
