The invention relates to a system (2) for detecting a fault state of a floating tube (4), wherein the system (2) has a buoyant floating tube (4), a detection system (6), and an evaluation unit (8), wherein the detection system (6) is designed to detect the geometric arrangement of the floating tube (4) and/or to detect the floating state (10) of the floating tube (4) in order to generate a detection signal which represents the detected geometric arrangement of the floating tube (4) and/or the detected floating state (10) of the floating tube (4), wherein the detection system (6) and the evaluation unit (8) are coupled via a first signal connection (14) in order to transmit the detection signal from the detection system (6) to the evaluation unit (8). There are multiple possible fault states here which can be detected by the evaluation unit (8). These fault states include a crossed arrangement of tube portions (12) of the floating tube (4), tube portions (12) of the floating tube (4) which can be in a decoupled state from the rest of the floating tube (4), tube portions (12) of the floating tube (4) which are fully submerged in the water, and/or the detection of an at least partly coiled arrangement of the floating tube (4).

Illustrated and described is a floating hose segment (4) with an inner hose element (14) which has a first outer surface (22) which faces away from a line region (16), an outer hose element (24) which has a second inner surface (26) which delimits an interior space through which the inner hose element (14) extends, and a second outer surface (28) which faces outward away from the inner hose element (14), and a communication device (46) which is adapted to transmit information directly or indirectly to a central control device (54), wherein at least one sensor device (42) is provided which is adapted so as to be capable of detecting the presence of at least one substance in the region between the first outer surface (22) and the second inner surface (26), wherein the at least one sensor device (42) is linked to the communication device (46) such that information relating to the presence of the at least one substance between the first outer surface (22) and the second inner surface (26) can be transmitted to the communication device (46), and wherein the communication device (46) is adapted to transmit the information relating to the presence of the at least one substance between the first outer surface (22) and the second inner surface (26) to the central control device (54). A floating hose system is moreover described.
