Meteorology

Through the last ten years we have specialized in the construction of meteorology towers (measurement towers), making us one of the leading suppliers in Europe today. We work for many of the large wind turbine producers, installation companies, wind measurement companies and energy suppliers.

The close cooperation with the large producers and specialists in wind measurement has given us very specific knowledge and knowhow. We can therefore offer our customers professional counselling and service, ensuring them a perfect solution which fulfills their demand for good and reliable wind measurements. Correct measurements are decisive when choosing the correct wind turbines for the specific conditions. It has been seen in several cases that imprecise measurements have had fatal consequences for the success and profitability of the wind turbine park.

To ensure our customers optimal wind measurements we have tested our MET-tower to find out how far from the tower the measurements must be made; measurements which comply with the IEC 61400 standard of maximum 1 percent wind distortion. Therefore we know exactly how long the booms must be to comply with this standard - and by that we can give our customers correct and reliable measurements.

Temporary or permanent tower

There are different types of meteorology towers and you can distinguish between the temporary and the permanent meteorology towers.

Permanent measurement towers are often self supporting towers because they are very strong and can withstand all kinds of weather. They can be installed up to 30 years and demand minimal maintenance.

Temporary towers are used in different ways. Sometimes they are installed for a period of 3 months to 3 years before the installation of the wind turbines, in order to analyse the wind conditions in different heights. In other cases the temporary towers are used for calibration of the wind measurements, in order to make them as accurate as possible. More specific, this means that you install a tower at the exact place where the wind turbine should be installed. Then you install a permanent tower nearby. With these two towers you are able to measure the winds from two places and can thereby increase the reliability of the result. Later, when the temporary tower is removed and the wind turbine is installed in the same place, you know exactly which effect the wind has on the wind turbine, based on the continuous measurements from the permanent tower. In the large wind turbine parks there are usually serveral positions to measure from, thereby getting both "up-wind" and "down-wind" measurements. In addition to that, it is an advantage to have several towers installed around the wind turbine park, making it possible to compare winddata from several positions and thereby optimize the performance of the wind turbines.
