ABSTRACT:
A fault detection system for subsea pipeline DEH cable includes fiber optic element(s) (7) provided along the cable section concerned and located outside at least some of the cable insulation (2,3,4). The fiber optic element(s) are adapted to be influenced by fault inducing effects or damages to said cable section, so as to bring about an optical signal indicating a fault condition. The main feature of the invention is that said fiber optic element(s) (7) extend(s) inside a tubular, electrically conductive metal element (7a) adapted to melt down in the case of a fault current flowing therethrough as a result of damage to the cable insulation (2,3,4) at a point along said cable section.
