Abstract : The invention relates to cable suspension of loads from a ship and, in particular, to elastic cables capable of absorbing cable-tension forces produced by wave action and the like. The cable includes bundles of plastic-impregnated nylon fibers acting both as strain members and strain accumulators. An inner core bundle is wound with an electrical conductor that stretches with the fibers when the cable is tensioned. The winding pitch assures that the fractional change in volume per fractional change in length is the same for the winding as it is for the fibers. An outer sheath-like bundle surrounds the inner bundle and its winding. Prefera bly, the cable is used as a limited length section of an otherwise conventional co-axial cable for suspending various objects from a ship. The section length is limited to that needed for its accumulator action. (Author)
