The problem was being attended to by RInfra and HPGCL engaged the Department of Civil Engineering,Indian Institute of Technology (IIT),Roorkee for an independent evaluation of the quality of concrete in the foundation structure and the bearing pedestals of the Turbo Generator of Unit-1.

A team of civil engineering experts from IIT Roorkee comprising of Dr Umesh Kumar and Dr Bhupinder Singh visited RGTPP on July 17 and 18,in this regard. The machine was rolled on July 25,by RInfra under the supervision of SEC experts,however the vibration problem still persisted.

“Since the Unit could not be revived,inspite of repeated trials and addition of balancing weights,HPGCL contacted M/s Sampoorna Rotor Dynamics Consultancy (SRDC),Hyderabad which is represented by IIT professor and renowned vibration expert Prof J S Rao and other turbine experts including Dr K V Bhaskar Sharma and Dr MCR Prasad,and requested them to visit RGTPP to examine the problem and suggest solutions. Further,another reputed turbine expert Baboo Ram was also requested to visit RGTPP in this regard. All the above experts visited RGTPP site on August 1 and August 2,to study the problem and suggested remedial measures to be undertaken by HPGCL,” the spokesperson mentioned.
