After its 8 MW offshore wind turbine was certified as typhoon-proof las year, Siemens Gamesa has received a second rotor-nacelle assembly (RNA) IEC type certificate covering resistance to extreme wind conditions, this time for its 11 MW model.

Issued by TÜV NORD, the certificate confirms the two Siemens Gamesa machines are able to withstand Typhoon- or T-class wind speeds as determined by the IEC reaching 57 metres per second for 10 minutes and three-second gusts of up to 79.8 metres per second.

“We are driven to ensure that our turbines can sustain the extreme weather events such as typhoons seen in Asia Pacific. We’re thus tremendously proud to have received this second rotor-nacelle assembly type certification. With the region poised to become even more significant globally, it strengthens our focus on delivering value to our customers”, said Marc Becker, CEO of the Siemens Gamesa Offshore Business Unit.

The news comes a little over a month after Siemens Gamesa secured a Full Type Certificate for the SG 11.0-200 DD wind turbine from TÜV NORD, one year ahead of time.

Love seeing such resilience planned for-- it's truly necessary. 

You do always wonder about the difference between a lab setting and reality, though. Have any of the turbines that are rated for typhoons been put through a real typhoon event after receiving that certification? Would love to see the use case story of them continuing to stand strong in those instances
