Fibre optic sensing boosts pipeline management efficiency. P. Orell. Pipeline Gas J., February 1995, 222(2), 44--45.

New fibre optic-based distributed temperature sensing (DTS) equipment is recommended for simultaneous monitoring of thousands of data points. Trials using DTS equipment for detecting leaks in natural gas liquids pipelines and in LNG pipelines operating at -320 degrees F are discussed. Development of a DTS system by York Sensors Ltd. is described. The optical fibre cable is small and flexible and responds almost immediately to pipeline temperature changes. Installation of optical fibres encapsulated in fine strainless steel tubes or set in concrete is described. Results show that this technique has significant advantages over conventional infra-red thermal monitoring devices. DTS systems are particularly suitable for use in hazardous environments.
