However, condition monitoring systems based on many discrete sensors are generally not well-suited for widespread piping systems due to considerable installation effort, while use of distributed fibre-optic sensors would reduce this effort to a minimum. Specifically distributed acoustic sensing (DAS) is employed for detection of third-party threats and leaks in oil and gas pipelines in recent years and can in principle also be applied to industrial plants. Further possible detection routes amenable by DAS that could identify damage prior to emission of medium are subject of a current project at BAM, which aims at qualifying distributed fibre optic methods such as DAS as a means for spatially continuous monitoring of industrial piping systems. Here, first tests on a short pipe are presented, where optical fibres were applied directly to the surface. An artificial signal was used to define suitable parameters of the measurement system and compare different ways of applying the sensor.

Ein weiterer Schwerpunkt ist auch die Datenerfassung und Analyse. Hierzu gehören eine Sensitivitätsanalyse des gesamten Messsystems und die Ermittlung und Klassifizierung der Schallsignaturen spezifischer Schadensbilder. Aufgebaut wird dabei auf Erfahrungen aus Schallemissionsmessungen an Werkstoffproben und Bauteilen zum Nachweis von aktiven Schädigungsprozessen (z.B. Risswachstum) oder passiven Schädigungen (z.B. Muldenkorrosion in durchströmten Leitungen). T2 - 1.

Special attention is paid to the optimal application of the fibre optic sensor for achieving high sensitivity towards acoustic signals. First results of real scale bending tests are presented, where cracks developing in the pipe material were initialized and analyzed with respect to their acoustic characteristics.
