FIELD: structure monitoring device.
SUBSTANCE: device consists of a basic carrier cable laid along the whole of the pipeline; there are four distribution location each of them containing four individual optical fibres which are virtually taps of the cable aforesaid laid around the flow string at 90° angles, each of the above optical fibres containing multiple strain sensors arranged along the flow string axis at a 90° angle relative to each other and in a circumferential direction relative to the flow string.
EFFECT: facilitated collection of data on the pipeline strain and deformation with the help of an optical fibre.
