Cable Suspension Systems In the study program, the analysis of cable suspension systems was based on the assumption that the cable is affected by its own weight and the trace configuration it assumes when deployed. The suspension system was primarily studied for use with surface-tendered power units. The length of cable, which determines the cable weight, is a function of the depth of the load module and the excursion of the surface unit. The excursion of the surface unit depends, in turn, on the environment in which it is placed. Since the environment could not be predicted, the cables were chosen to include those lengths which might be required to reach depths of 600, 2,000, 6,000, 10,000, 15,000, and 20,000 feet. To limit the length of cable required, the center of excursion for the surface unit should be placed directly over the load module. However, it has to be assumed that the surface unit travels through its excursion limits for an unknown number of cycles during its deployment. This cycling causes a 59.
