Abstract
A sensor for measuring a characteristic of a length of a pipeline, wherein the sensor comprises a sensor length arranged to extend helically along the pipeline length; and the sensor length extends parallel to a ridge extending radially from a layer of a wall of the pipeline length. A length of pipeline with an integrated sensor length may be constructed by bending a first strip of material into a helical form that comprises a first ridge; bending a second strip of material into a helical form, wherein the second strip of material comprises a second ridge; forming a tubular shape from the first and second strips of material, wherein the first strip of material at least partially surrounds the second strip of material, and the first ridge engages the second ridge; and wrapping a sensor length about the tubular shape.
Claims8
A pipeline system comprising a pipeline length and a sensor for measuring a characteristic of the pipeline length;
- the pipeline length comprising a pipeline wall, the pipeline wall comprising a plurality of layers, the plurality of layers of the pipeline wall forming a ridge, the plurality of pipeline layers engaging at the ridge, the ridge extending radially outwardly from an exterior surface of the pipeline wall, and the ridge extending helically along the pipeline length;
- and
- the sensor comprising a sensor length extending helically along the pipeline length, the sensor length extending helically around an outside of the pipeline length parallel to the helical ridge, the sensor length abutting the ridge at the exterior surface of the pipeline wall outside of the pipeline length, and the sensor length being an optical fibre;
- wherein
- the measured characteristic by the sensor is a presence of a strain of the wall of the pipeline length.
