    摘要： A flexible pipe fatigue monitoring system 30 comprising a pipe monitoring system 32, 40, 42 adapted to be provided on a flexible pipe 10 having a bend stiffener 18. The pipe monitoring system 40, 42 is provided on the pipe 10 below the bend stiffener 18. The monitoring system 32 measures one or more of bending, tension and torsion of the pipe 10. The pipe monitoring system 30 comprises sensor carrier members 40, 42 adapted to be coupled to the pipe 10 and at least one fibre Bragg grating strain sensor embedded in a carrier member 40, 42. An inclinometer 34 is provided on one carrier member 40 to measure the incline of the pipe 10 relative to earth. A central processor 38 is provided to receive bending, tension and torsion information and incline information, and is operable to determine pipe fatigue from said information. A method of flexible pipe fatigue monitoring is also provided.

    摘要： A system and method for measuring loads on a pipe, including a pair of collars that can be secured around the outer surface of the pipe to be monitored in an axially spaced relationship; and a connecting element having a strain gauge is fixed to the collars such that when the collars are secured to the pipe, the connecting element is arranged to measure distortion of the pipe due to applied loads, wherein the ends of the connecting element are attached to the collars such that when the collars are secured to the pipe, the ends of the connecting element are fixed against axial and circumferential movement relative to the pipe. The system includes the apparatus mounted on a pipe, such as a flexible pipe, in a subsea oil or gas installation.
