The present invention relates to a method for monitoring the torsion of a cable comprising the steps of: providing a cable having an outer surface and extending along a longitudinal direction, the cable being provided with at least one identification tag, preferably am RFID tag, arranged in a tag angular position in a cross-sectional plane taken transverse to the longitudinal direction, the at least one tag storing a tag identification code and being capable of transmitting a tag electromagnetic signal; interrogating the at least one identification tag to receive the tag electromagnetic signal, and detecting the tag electromagnetic signal, wherein the step of detecting the tag electromagnetic signal comprises the step of reading the tag identification code and determining the tag angular position of the at least one identification tag. In another aspect, the invention relates to a torsion monitoring system of a cable comprising at least one identification tag. Preferably, the cable is provided with a plurality of identification tags, each tag of the plurality being arranged in a respective tag angular positions.
