U.S. extends platform, turbine blade query for 2,160-MW John Day

The U.S. Army Corps of Engineers has extended the deadline to submit information on firms capable of supplying a turbine maintenance platform and of performing turbine blade sealing, pinning, and tip gap filling at 2,160-MW John Day Dam, on the Columbia River in Oregon. Responses to separate notices now are due Sept. 23.

It is to be made of segments that can fit through a 3- by 2-foot draft tube door, be assembled in the draft tube, and be raised into position.
