Description

Optical fiber strain sensors embedded within load-bearing cables may pose an effective and inexpensive approach to extending the service life and load capacity of such cables. Currently cables must be replaced according to a conservative schedule based on mean-time-before-failure statistics in order to prevent failure of the cable. Real-time, in-service measurement of cable mechanical parameters by optical fiber sensors may prevent premature and expensive retirement of cables, and will minimize exposure of personnel to catastrophic cable failure. Also, the cable may be rated for greater load capacities, since active monitoring means that conservative rating is not necessary.
