Troubleshooting

During both implementation and operation, prime contractors and industrial companies sometimes have to face acoustics and vibration related problems.

METRAVIB team of experts is visiting sites around the world to assess and diagnose these issues. Indeed it is essential to measure phenomena such as noise emission, static or dynamic structural behavior in real operating conditions in order to analyze any deviations or the causes of faults.

Such field services go hand in hand with:

  • Equipment acceptance tests according to requirements imposed by international standards
  • Troubleshooting and seeking the causes of faults
  • Performance improvement and optimization
  • Competitive or benchmarking studies

Unexpected/ Unwanted noise or vibration

When engineers or technicians are confronted with unapprehended vibration or acoustical phenomenon, they tend to use familiar analysis tools or refer themselves to past experiences. Sadly, physics cannot be summarized in one tool and has many ways to express itself !

METRAVIB uses for instance the following methodology for troubleshooting studies in Oil and Gas market: see download button below.

Services for diagnostic

When it comes to provide the right support in critical situations, METRAVIB team of engineers and technicians is at your side, responsive, making the best use of our experience, skills and tools offering:

  • Sound Power and Sound Intensity Measurements
  • Experimental Modal Analysis
