Figure 23. Taut cable support system. 



The above configurations are based on tlie assunnption that the total 

 cable suspension system is slightly negatively buoyant. If it is made positively 

 buoyant, the cable system will probably broach the surface during the excur- 

 sion of the surface unit and be subjected to surface conditions as well as to the 

 possibility of becoming entangled with the mooring system. 



Both the taut line and the catenary system suffer from the fact that if 

 the cable is lost at any point below the attachment to the last support buoy, 

 the cable complex will descend to the bottom. The cable would have a higher 

 probability of falling on the load module with the taut line system. Suspension 

 systems for underwater cables will require careful analysis during system design.
