Onshore wind turbine: VIV during installation

Wind turbines are strongly exposed to Vortex Induced Vibrations (VIV) in the installation phase.

Read more about the problem and recommended countermeasures.

Wind turbine installation
Smokestack with TMD. The TMD reduces VIV by increasing the Scruton number.

Smokestack TMDs are sometimes hidden inside the cylindrical stack, typical for large diameter multi-pipe stacks. Here, the TMD is in the annular chamber near the stack top.

Smokestacks are exposed to Vortex Induced Vibrations (VIV), leading to significant risks.
