The company itself has sent a report of concern to NVE and Sortland municipality, which tells of several serious episodes at the plant. - There is such a great risk of falling objects that NVE must be notified. After the latest events in 2021, we have become concerned that this is a recurring problem, writes Astrid Fosså Ekseth in a letter to NVE. She is general manager of Ånstadblåheia Vindpark AS.

At the windmills on Ånstadblåheia, there have been 6 serious incidents where the cover on the turbine top has fallen to the ground. Now the owners are warning both the municipality and NVE about the situation.

Walking near the windmills at Ånstadblåheia can be very dangerous. This applies both when there is a possibility of ice floe when there is frost, but also when there is strong wind.

On top of the turbine housing is a cooler top, which is covered by a fiberglass cover. We have experienced on several occasions that the cover has fallen off in strong winds.
 
- The reason why we are now reporting this to the authorities is that for the first time on 27 April this year we experienced finding a fallen cover without having identified when it had fallen off, says Ekseth.
 
The defect has been notified to the equipment's supplier, Vestas, on several occasions, which has assured that the company is working on a solution at group level.
 
The wind turbines at Ånstadblåheia are of the Vestas V126 type and were installed in 2018.
 
- We see a great need for improvements before the summer season before outdoor activities start to a large extent. As of 28 April, a total of five turbines experienced falling cover parts at Ånstadblåheia wind farm, Astrid Fosså Ekseth informs.
 
The parts can pose a danger both when they fall from the turbine housing and as loose parts if they are carried away by the wind.
 
- We do our utmost to ensure that the supplier follows this up and implements the necessary measures.
 
Until a final solution is in place for all turbines, we have given Vestas written instructions that all turbines must be inspected after each storm.
 
All turbines have been inspected to uncover any cracks in the spoiler at an earlier stage, says Astrid Fosså Ekseth.
 
She points out that there is no written documentation that this is a challenge at other wind farms in Norway, but draws NVE's attention to the fact that this is a standard off-the-shelf item for all similar turbines.
 
Fortum therefore sees this as the supplier's responsibility to improve as soon as possible to ensure the safety of the public and employees in the area.
 
Both in January, March and April this year, it has been seen that parts of the covers have fallen down. The same thing was discovered three times last year, and there are therefore 6 registered incidents.
 
At Ånstadblåheia there was a storm with hurricane force winds on 6 April this year, and there are many indications that cover may have fallen then, although it was not discovered until twenty days later.
