This is much smaller than assumed when the footings were first sized; 

 therefore, B can be reduced. 

 For B = 7.0 feet, 



F = 2105 pounds, which is satisfactory. 



Use B = 7.0 feet. 



Check required keying edge depth, 



d = 0.17 + 0.05 * B = 0.52 feet (6) 

 e 



Total submerged weight will also be reduced but likely not sufficiently 

 to affect this design. 



Emplacement 



Maximum lowering rate for this installation, 



A = 44 + 2.5 * (3.5) 2 * 3.14 = 140 square feet 



V = 1/4 * /w ~ -t A =1.5 feet per second (15) 

 max v sub v 



This means that it will take at least 2 1/4 hours to lower the installa- 

 tion to the seafloor. 



Maximum lateral excursion, 



r = 10 * A * d ■} W , = 1450 feet (17) 

 1 sub 



Handling characteristics, 



r, = 6.4 feet, ship has limitation of 14 feet, therefore, satisfactory. 



z, = 10.6 feet, have 22 foot limitation, therefore, satisfactory. 



W , = 4770 pounds 

 sub v 



W dr = 6200 + 2550 = 8750 pounds, have limitation of 10,000 pounds, 

 therefore, satisfactory, but since this is so close it would 

 be advisable to check the handling system to assure its rated 

 capacity
