The windmills at Ånstadblåheia are exposed to extreme weather conditions. Two weeks ago it happened again, that parts of the turbines fell off in strong gusts of wind. This has happened several times before. On 15 March this year, several parts of a turbine were found on Ånstadblåheia, after a period of very strong winds. It was the supplier Vestas who discovered the objects.

On 15 March this year, several parts of a turbine were found on Ånstadblåheia, after a period of very strong winds.
 
It was the supplier Vestas who discovered the objects.
 
Among the things found are one side cover, a mounting bracket for a ladder and the ladder that was attached to the wind turbine.
 
On Thursday 10 March, it was very windy in Vesterålen and in exposed places there were wind gusts up to hurricane force.
 
It is likely that such gusts of wind have torn parts from the windmills on Ånstadblåheia.
 
However, this has happened before. 6 cases have been reported.
 
Both the owners and the supplier Vestas have therefore followed extra closely.
 
After the previous cases, several adjustments and securing of the turbines were made.
 
Vestas inspected all fittings and associated bolts in May 2021.
 
After the inspection, sensors were also installed on one of the wind turbines to measure vibration.

The windmills at Ånstadblåheia are exposed to extreme weather conditions. Two weeks ago it happened again, that parts of the turbines fell off in strong gusts of wind. This has happened several times before.

Vestas inspected all fittings and associated bolts in May 2021.
 
After the inspection, sensors were also installed on one of the wind turbines to measure vibration.
 
The supplier Vestas uses so-called "Cooler Tops" on thousands of wind turbines globally.
 
Ånstadblåheia Vindpark AS says it has not received information from Vestas about similar incidents in other wind farms.
 
The company will now ask Vestas to remove all fiberglass panels around the Cooler Top component.
 
- We consider the potential for falling objects to be greatest in connection with strong winds above hurricane force, says Noor Nooraddin in Fortum in a letter to NVE and Sortland municipality.
 
- With lower wind speeds in the spring and summer months, we believe that the risk of falling objects will be reduced towards the summer.
 
We already have the warning system for ice floe, and are considering whether it is appropriate to introduce similar warning systems in the event of strong winds.
 
Ånstadblåheia Vindpark takes this matter very seriously and is in close dialogue with Vestas to reduce the risk of falling objects as quickly as possible, says Noor Nooraddin.
 
It is recommended to keep a distance of 200 meters from the turbines, especially if there is a risk of ice floe and strong winds.
 
This means that an area of ​​125 acres is seized around each wind turbine.
 
With 14 windmills on Ånstadblåheia, access to a full 1,750 acres on the mountain is therefore limited.
 
A residential plot is normally about 1 hectare, or 1,000 square metres.
 
Here we are talking about almost the entire top of Ånstadblåheia being a danger area.
