The research submarine ALVIN was carried, launched, and recovered by a platform hoist located between the pontoons of the catamaran support vessel, LULU. (Figure No. 1) On October 16, 1969, the wire ropes of the hoist system failed and the submarine ALVIN was lost. The modes and causes of the failures were subsequently investigated in a comprehensive test program. Methods and results of this experimental analysis are hereafter reviewed.
