Study of Electromechanical Cable Testing and Test Specifications
2007
Minor, John C.
The program was to analyze present electromechanical (E/M) cable testing and test specifications for cables used in the deep ocean and to recommend research programs to correct and improve deficient areas. The work included a survey of the literature and contacts with the major E/M-cable manufacturers, users, and testing agencies. E/M-cable types were identified by application as bottom-laid, suspended-array, or ship-stored cables. Major problem areas, such as corrosion, fish-bite, and kinking, were discussed. Presently used testing methods and test applications were summarized. Four research programs were recommended for developing standard test methodologies to be applied to E/M-cable testing: (1) Breaking Strength, Tension/Elongation, Tension/Rotation, and Tension/Rotation Tests using a Tensile Test Machine; (2) Tension/Rotation and Susceptibility-to-Kinking Tests Using a Suspended Cable with Attached Weights; (3) Bend-Over-Sheave Tests; and (4) Hydrostatic Pressure Tests.
