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 an economic operation. This is why the quality of wind measurements is our highest priority: today our measurement masts reach heights of 160 metres and above. 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 studies 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. Our guaranteed data availability of 98% is unrivalled in the industry.
