Risk-Based Inspections can optimize inspection cost through prioritisation of high-risk failures and adaption of inspection intervals for low-risk failures. Find out more in our White Paper.

Up to now, lifetime extension reports have usually been based on historical operating and wind data as well as turbulence reports. Due to conservative load assumptions and insufficient consideration of the wind direction, however, the potential for continued operation for as long as possible is often significantly underestimated. Based on the accelerations measured in the tower, SHM.Tower calculates the real occurring loads distributed over the tower cross section and thus allows an exact statement about the actual lifetime consumption. The lifetime extension can be maximized and the entire yield potential can be tapped. This methodology has now been successfully evaluated by Deutsche WindGuard. In our White Paper, you can find out everything about how it works, the validation project and the areas of application.

Does your WT have service life reserves? This question cannot be answered adequately based on historical wind data, because the actual load of the individual wind turbines varies considerably. Find out in our white paper how you can use Structural Intelligence to make technically sound decisions about further operation based on real fatigue loads.

Structural Intelligence in wind turbines allows for the monitoring and evaluating of the lifetime of the towers during operation. The data collected serves as the basis for lifetime extension assessments: The measured fatigue loads show the actually consumed lifetime of the towers.

The structural integrity of wind turbine generators (WTGs) must be ensured in particular by the two supporting structures, the tower and the foundation. Damage to these structures poses a considerable risk to the stability of the WTG and the safety of people. For this reason, they must be detected at an early stage and permanently monitored with a suitable system.

A wind turbine is one of the industrial structures with the highest vibration loads within its lifetime. It has to withstand up to 250 million load cycles within approximately 20 years. The vibration loads of wind turbines vary considerably depending on the location and operational mode of the wind turbine.
Even two wind turbines in the same wind farm may differ significantly in their vibration loads. In the design phase, these loads can only roughly be determined leading to potential reserves of turbine’s lifetime during operation.
