Abstract : To establish the degree of agreement between theoretical and experimental results, tests were conducted on high-mass, low-drag bodies (a reinforced concrete sphere, a cylinder, and a parallelepiped) suspended from various lengths of nylon line and steel wire cable. Random excitations were induced in the loaded cables by the roll, heave, and pitch of the drifting test ship from which the loaded cable was suspended. Except for apparent frequency shifts in the response amplitude operators for loaded nylon lines at the greater depths, there was good agreement between the theoretical and the experimental results.
