Seismic Instrumentation – Permanent Earthquake Monitoring by Wölfel

Earthquakes are unpredictable. In the event of an earthquake, there is a risk of direct and indirect damage to industrial plants, conventional and nuclear power plants and other building structures located in the affected regions. Infrastructures such as bridges, containers for the storage of hazardous substances or dams are also at risk.

In cooperation with the technology of the Swiss manufacturer SYSCOM, Wölfel offers you seismic instrumentation for the continuous measurement of the effects of vibrations and for reporting in the event of limit values being exceeded. By automatically comparing the measured vibration with the stored design values (e.g. response spectrum), it is possible to check the building or system section. This enables you as the operator to automatically switch off or secure critical processes or plant components. On the basis of the recorded measurement data, a mathematical re-evaluation and thus a conclusion on the stability of the affected buildings is possible.

Wölfel supports plant operators in keeping the risk of exposure due to earthquakes as low as possible. We accompany the entire process from the conception of a plant up to the coordination with appraisers as well as the delivery of necessary verifications. Our portfolio ranges from certified systems, e.g. for power plant monitoring, to relatively simple "seismic switches" for the monitoring of buildings or shutting down machines and systems.  

Our services in the area of permanent earthquake monitoring include:

  • Delivery and installation of seismic instrumentation, if required according to relevant regulations such as KTA 2201, IEC 61508 (SIL 2 and 3), IEC 60780, IEC 61226 (CAT A and C) or IEC 60880 (CAT A)
  • Development of concepts regarding the replacement of existing (third-party) instrumentation
  • Detailed designs including necessary arithmetical verification
  • Support in authorization procedures
  • Generation of design review documents and complete project documentation
  • Performance of Factory Acceptance Tests with expert participation
  • Installation, commissioning, service, maintenance and training
