Siemens Gamesa builds world’s largest blade test stand

244

Siemens Gamesa Renewable Energy (SGRE) has begun construction of the world’s largest wind-turbine blade test stand in Aalborg, Denmark. The site will be capable of performing full-scale tests on the next generations of SGRE rotor blades and is expected to be fully operational before the end of 2019.

This significant R&D investment in extensive testing will represent additional savings for SGRE’s clients in the future. Such high value-adding R&D activities enable the company to significantly reduce the risk of technical issues and simultaneously deliver wind turbines that are innovative and reliable.

“The first tests will be on the 94-meter-long blades for the SG 10.0-193 DD offshore wind turbine, which are almost the same length as one soccer field,” said Vicente García Muñoz, head of Validation Means Management at SGRE. “We are, however, building the test stand to accommodate the blade sizes that we will see in the future.”

The gigantic structure in Aalborg will have more steel rebar reinforcement per square meter than a wind-turbine foundation, so that it has the capability to accelerate the test and prove full reliability over the lifetime of the blade in the shortest possible time, while respecting IEC regulations.
