In the event of a storm, the offshore wind turbine must withstand not only strong gusts of wind but also large waves crashing over the mast. The combination of these two phenomena creates significant strain on the mast.
DEWI (the German Wind Energy Institute) is a certified body tasked with conducting measurement campaigns intended to check that the behaviour of wind turbines corresponds to applicable standards.
We proposed OBSG-60 strain gauges and OBTS-100 temperature sensors. They are measured by the toughened MDX-400T-X unit. The sensors are attached to a section of the mast and measure its inflection.
