Abstract: A method and apparatus for detecting pipe entrenchment or upheaval of a flexible pipe and/or the presence of an external feature to the flexible pipe are disclosed. The method includes helically winding a temperature sensing element (204) around a layer of a flexible pipe; helically winding a heating element (206) around a layer of a flexible pipe; heating the heating element to a pre-determined temperature; measuring the temperature at at least two locations along the flexible pipe; comparing the measured temperature response at the at least two locations; and making a determination, from the comparison of measured responses, regarding the exterior vicinity of the pipe at one of the at least two locations.

Abstract: A method and apparatus are disclosed for determining a bending radius of a flexible pipe. The apparatus includes at least one bend sensor element comprising an elongate flexible substrate and at least one bend sensitive element on the substrate that has at least one electrical characteristic that is responsive to angular displacement of the substrate. The apparatus also comprises a flexible crush resistant elongate housing that supports and surrounds the bend sensor element.
