The Siemens Energy division at Vadodara, Gujarat, India, provides turbine, compressors, and induced-draft fan solutions for power plants. One Siemens project was for Godavari Green Energy Limited, a 50MW facility in Nokh, Jaisalmer, Rajasthan. This was India’s first solar thermal power plant, which recently began operations. The client was Godavari Power and Ispat Ltd., and Siemens’ scope included engineering and supply of the turbine, generator, auxiliaries, and steam piping.
The pipe ranged from 15NB to 250NB in diameter providing systems with auxiliary, sealing, and leak-off steam at temperatures of up to 400C. The project also encompassed the lube and high pressure oil systems, the condensate, and vacuum pump piping.
The configuration of the turbine facility made the overall piping arrangement very cumbersome and rigid. With the anchor point in the center, the thermal expansion on the smaller-diameter turbine nozzle is high, meaning allowable loads on the nozzle are far less.
Siemens had only six months to release stress reports and hanger specifications, and there was no database available for valves, specialty items, turbine, or structures. The project also required coordination with a US-based consultant in key areas, adding to the challenges.
Siemens received the 2014 CAESAR II Drivers of Success Runner-Up Award for its use of the software. The annual Drivers of Success competition recognizes innovative applications of Intergraph products, impressive project results, and significant benefits from collaboration among disciplines and the integration of the products.
