X-DOF

About

Jr. nr. 64016-0121
​The purpose of this project is to establish demonstration, develop solutions fit for market and prove through a series of sub-component tests and on a 7MW off-shore turbine that the technology is ready for market introduction. The outcome of the project will be cost effective product for retrofit and new design.​ The project is an integrated part of a European consortium “DemoWind 2 ERA-NET CoFund Action” with the purpose of delivering cost reduction in Offshore Wind. ​The X-DOF project is supported by the Energy Technology Development and Demonstration Program (EUDP), which is administered by the Danish Energy Agency.

X-Stiffener™

The X-Stiffener™ prevents longitudinal cracks on the leading edge of the blades. Longitudinal cracks on the leading edge are very often found after only a few years of operation. The X-Stiffener™ connects the two sides of the blades like a cross in a bookshelf. Experimental and theoretical modelling has proven that the X-Stiffener™ significantly reduces the twisting and hence the peeling stresses are reduced to non-critical levels.​

RATZ - (Root Area and Transition Zone)
The aim of this project is to demonstrate and develop a retrofit solution, the Floor™ (a Bladena patent), for avoiding crack development due to edgewise loading of the blade. The project address a serious problem seen in the field, which pose an extensive operation and maintenance cost for the wind turbine owners.
