are the start of any wind energy project. They are the prerequisite for selecting the right location for turbines, the right type of turbine and for economical operation. This is why the quality of wind measurements is our highest priority: our measurement masts today reach heights of 140 metres and higher. They perform their duty even under high snow loads and at the highest wind speeds, for example offshore. At sea we have set new standards in equipment, installation, power supply and reliability not just in the measuring device. Our study into the mechanical loads of offshore foundations of other components made from steel and plastic is helping designers to find constantly improved structures for the load bearing design. The data availability of 98% guaranteed by us is unrivalled in the industry.
