Siemens Saves 500 Hours with CAESAR II® forAluminum Installation in India
Siemens Group is a global developer and implementer of technology-enabled
solutions that support the world’s quest for developing modern infrastructure forenergy, healthcare and industry. The Siemens Group in India includes 17 companies
that employ over 18,000 people and operate 21 manufacturing plants and a wide
network of sales and service offices with over 500 channel partners. The Siemens
Oil & Gas unit at Vadodara in Gujarat, India, provides medium- and small-scale
power plants with turbine, compressors and induced fan solutions. The unit has
provided more than 500 turbines for global installations.

Engineering New Steam Turbine Generator for Hindalco
Aluminum Installation
Hindustan Aluminium Company Ltd. (Hindalco), the world’s largest aluminum rollingcompany and the aluminum giant in India, awarded Siemens the Hindalco 1 x 100
MW steam turbine generator Unit #5 project which included engineering, supplyand installation of the turbine and auxiliary facilities within the turbine generator
boundary, with the only exceptions being boiler, civil and structural engineering.
Pipe sizes ranged from 15 to 650 nominal bore (NB) diameters with material ranging
from A106Gr.B carbon steel to SA335 P22 alloy steel pipe. Deliverables such as
documents and reports included stress isometric drawings, code complianceand stress summaries, load case reports with the restrain summary, a hanger
datasheet and bills of material including plot snaps and deflection shape snaps.

Eliminating Conflicts between Clients and Vendors toExpedite ProjectBecause Siemens had successfully completed four similar scope units using
CAESAR II®, Hindalco had high expectations for the completion and execution ofthis project. Demonstrated advantages included the effective data transfer andformatting in CAESAR II which made it easy for communication and knowledgetransfer among all parties involved, which helped eliminate conflicts and disputes.

Despite a tight schedule of 18 months, Siemens was able
to match up various milestones, such as final piping layout
and piping loads for civil and structural design while also
addressing changes prior to finalizing the stress analyses
and bills of material, all made possible by CAESAR II. Theuser-defined spring datasheet capability in CAESAR II
helped minimize rework from site modifications, further
expediting the project’s schedule for the customer.

Saving 500 Man-hours and Related Expenses
with CAESAR II’s Accuracy
Siemens was able to save nearly 500 man-hours byleveraging CAESAR II features, such as user-defined
supports, stress isometrics and export restrain summaries
plus sharing earlier unit models. This helped save
approximately 0.75 million Indian rupees. The project wasa major success, and it is now included in Siemen’s project
portfolio.
“Reliable results, exclusive features of support selection
and the capability of modeling all site conditions withCAESAR II were critical to this project’s success,” explained
K.G. Brahmbhatt, head of Siemens’ project engineering
analysis for the facility. “These proven advantages make
CAESAR II a widely popular and preferred solution within
the power industry.”
