Tubular steel towers can be exposed to strong vibrations which significantly affect the lifetime of a wind turbine. SHM.Tower detects the tower vibrations with sensors and documents extreme loads and fatigue loads as well as the lifetime consumption, for up to two months even without power supply.

SHM.Tower is easy to retrofit, so that a lifetime assessment is also possible at the end of the operating period of the wind turbine. The solution offers:

  • Analysis of vibration velocities and accelerations according to ISO 10816‑21/VDI 3834 for the assessment of tower and nacelle vibrations
  • Determination of average / maximum vibration velocities, vibration accelerations and deformations; classification according to operating conditions; frequency of events when thresholds are exceeded according to ISO 10816‑21
  • Overviews of occurring vibration levels and the related lifetime consumption (annual / monthly / daily curves)
  • Lifetime calculation by means of fatigue limit
  • Classification of loads according to operating conditions (configurable)
  • Individual lifetime assessment for each tower segment and for flanges
  • Connection to the Wölfel monitoring portal MIC.Wind for the presentation of results
