US: Moventas Americas rolls out breakthrough up-tower planetary repairs for the Siemens 2.3 fleet

Following the GE 1.5MW repair capability announced recently, and continuing in the goal of developing groundbreaking standards and processes in the wind industry, Moventas is proud to announce that all failed ‘low-speed’ planetary stage gears and bearings in the Siemens 2.3MW wind turbines can now be repaired up-tower.

Similar to GE 1.5 up-tower repairs, this new up-tower repair capability for the Siemens 2.3 turbine promises to save wind farm owners significant downtime and expense.  With this new repair capability, gearboxes which would otherwise run to catastrophic failure up-tower, have options for life extension at a price that is a fraction of that associated with changing out the gearbox. 

The new repair process has already been successfully demonstrated on the leading gearboxes in the Siemens 2.3 turbines. In each repair, customers can opt for longer life components by upgrading the boxes up-tower from through hardened ring wheels and non-integrated bearings to state-of-the-art case carburized ring wheels and integrated planet wheel bearings 

“Following our game changing GE 1.5MW up-tower repair capability with this Siemens 2.3MW uptower repair, once again demonstrates our commitment at Moventas to provide drivetrain repair solutions that save customers the most money, reducing their cost of electricity,” said Steve Casey, Head of Moventas Americas' Operations.
