DETERMINATION OF WIRE ROPE TENSION BY FREQUENCY MEASUREMENT

One aspect of ever expanding ocean operations is the salvage or recovery of sunken vessels and other objects. In certain salvage situations, the wreck is raised in a nest of wire ropes rigged between paired lift craft. During the lift, it is essential that the tension in the wire ropes on the lift craft be equal. In one of techniques to determine it the salvage master "sounds" the wire with a hammer and judges the tension by ear. Well established theory is used to give a scientific method of relating the tension in the wire to the frequency at which it freely vibrates.
