The 985 ft. shot, which had been flaked out on the cat walk with 

 all floats attached before we left port (Fig. 5 -7)^ was now passed to 

 the Buoy Boat (Fig. 5-8) which pulled the top -end straight astern. 

 We then attached the bottom end to the 101 ft. shot (with some 

 difficulty because of inadequate provision for stoppering), and resumed 

 lowering on the synthetic line while the Buoy Boat maintained approxi- 

 mately 500 lbs. strain on the top end. This phase of the operation is 

 illustrated in Fig. 5-9. When the Coral Hook was estimated to be 

 200 ft. off the bottom we stopped lowering until the path of the barge 

 was directed toward the Station 4 site. We then resumed lowering 

 knowing that the coral hook and chain would lay down in the proper 

 direction. When the synthetic line went slack we cut it free, knowing 

 ftie anchor had bottomed. The Buoy Boat then set the top end free 

 with Marker Buoy (Fig. 5-10) attached. Periodic visual surveillance 

 of the Marker Buoys was maintained from the tracking towers. 



Because of the problem with dropped turns, 7 hours were required 

 to set the Western Outer Mooring, and the final phase involving 

 the Buoy Boat had to be carried out in darkness. The Eastern Outer 

 Mooring was set in 3 hours without serious difficulty. 



When the first outer moorings were set in November 1967, turns 

 were developed in the 985 ft. shots because they were lowered from 

 the YC-1378 and the synthetic tag line was not torque-balanced. Even 

 so, these moorings survived five months in the taut, vertical con- 

 figuration until April, 1968 when they were deliberately sunk to 

 remove a hazard to submarine navigation. 



5. 5 Formation of the Inverted "v" 



Fig. 5-12 attempts to illustrate this operation. On the day we 

 went out to form the inverted "v" the current was setting the sur- 

 face lines and Marker Buoys toward the East. We had loaded all 

 the necessary wire rope with floats attached on the T-426. We 

 then attached one end of a 1400 ft. float string to the top of the 

 Eastern Outer Mooring and passed the other end (attached to the 

 Head Frame) to the Buoy Boat which dragged the line up-current 

 as we payed it out from the T-Boat. Once this was completed, we 

 left the Buoy Boat to hold the float string toward the West and 

 steamed to the Western Outer Mooring. 



There we attached a 1471 ft. float string to the top end of the 

 mooring and fell back toward the Buoy Boat while paying it out. 

 When the end of the 1471 ft. of wire rope was reached, we attached 

 a 5/8 inch diameter polyproylene line and continued to fall back. 

 This synthetic line was 8 strand plaited and therefore nearly torque 

 balanced to avoid putting turns into the mooring cable. When we 

 reached the Buoy Boat she passed the Head Frame to us and we 

 lashed it to the gunwale.
