This work presents recent advancements in vibroacoustic technology (VT) for pipeline integrity monitoring, with a focus on enhanced flexibility and simplified deployment on existing infrastructure. The new hardware consists of externally mounted sensor blocks based on an interferometric principle, capable of sensing Vibroacoustic waves inside the...

To ensure the safe transport of natural gas through steel pipelines, structural integrity must be assessed using fitness-for-service (FFS) methodologies. These assessments (ex. ASME FFS Level 2) require accurate inputs on material properties (particularly toughness), flaw/defect geometry, and loading conditions to evaluate the safety of pipeline...

In many technical applications pipelines are used for the transport of potentially flammable or hazardous gases and liquids. Vibration problems at pipelines often depend on the volume flow. Vortex shedding is a typical result of flow induced pulsations and may cause severe piping vibrations and failures. Another excitation source for critical...
