A flexible pipe system includes an unbonded flexible pipe connected to a floating vessel and a sensor system with an optical fibre integrated in the unbonded flexible pipe. Interrogating equipment transmits optical signals into the fibre, receives optical signals reflected from the fibre and detects a parameter of the unbonded flexible pipe. A turret connects the flexible pipe rotationally to the floating vessel via a swivel device that provides a fluid transfer passage between the turret and the vessel. The interrogating equipment is arranged on the turret and is further configured to transfer signals indicative of the detected parameter to receiving equipment on the floating vessel. In this way, optical signals reflected from the fibre can reach the interrogating equipment without distortion in the swivel, so that parameters can be detected with sufficient quality also for floating vessels equipped with a turret mooring system.
