Short-Term Capacity Sloping Seafloors 

 Refer to Kulhawy et. al., (1978). 



Short-Term Capacity Laterally Loaded Plates 

 Refer to Neely et. al., (1973). 



- Plate anchor capacity is enhanced with lateral loading. 



- For propellant anchors, keying distance is minimized. 



b. Long-Term Static Holding Capacity (full drainage) 



- Time to full drainage = f (permeability load, drainage 



path, anchor size, shape, etc.) 



Cohesionless soil - drainage almost immediate 



F,^ (cohesionless soil) = F ^ 

 It St 



Cohesive soil - long-term capacity governed by drained strength 



parameters: friction angle, ({>, and cohesion intercept c .
