Structural Health Monitoring

Wind turbines Structural Health Monitoring (SHM) is the use of metrology techniques and sensors to provide a continuous assessment of the state of engineering structures.

This assessment allows the owners of large engineering assets to schedule maintainance more accurately, and can give an early warning of possible structural failure.

NPL is currently involved in projects assessing many traditional and novel sensors for monitoring structures such as bridges and industrial machinery, and also the environments outside and within those structures.

Because SHM can produce a large amount of data, we are at the same time investigating data mining and visualisation techniques that can help extract and present the salient information.

NPL runs an industrial advisory group for organisations interested in the outputs of existing SHM projects, or in steering future projects. IAG Members have access to the Members Only area.

SHM research

  • NPL has considerable experience and the facilities to provide test methodologies and models that are required to avoid the catastrophic consequences that can result from the failure of materials in a wide range of different commercial applications.
  • A demonstrator to show the benefits of structural health monitoring and the advantages of using multi-modal monitoring methods to the wider civil engineering community.
  • Structural Health Monitoring (SHM) is the use of metrology techniques and sensors to provide a continuous assessment of the state of engineering structures.
