A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.

The invention concerns a hoisting cable formed of a steel core coated at its periphery with a textile sheath, wherein said textile sheath is a sheath directly braided on the steel core and made of an abrasion-resistant synthetic material.

The invention concerns the field of marine ropes, and more specifically a marine rope (1) comprising a plurality of cores (2; 2a, 2b), an individual coating (3) around each core (2; 2a, 2b), and a permeable protective sheath (4) around the plurality of cores (2; 2a, 2b). Each core (2; 2a, 2b) comprises a fiber strand or braid and each individual coating (3) is watertight and has a melting temperature lower than that of the corresponding core and an elongation at break greater than that of the corresponding core.

Disclosed is a non-steel strength membered high strength cable easily monitored for heat and elongation comprising a length of a core-cable (10), the length of core-cable (10) including at least two fiber-optic conductors (2) that are: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material.
One fiber-optic conductor capable of transmitting at least Raman backscattering and the other fiber-optic conductor capable of transmitting at least Brillouin scattering.

A combination of the cable (10): (i) with an interrogator that can read and interpret Raman backscattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Raman backscattering; and (ii) another interrogator that can read and interpret Brillouin scattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Brillouin scattering;
permits ascertaining the elongation of the cable, without using loose tube fiber-opticplacement.
