TB product life extension
• The original PRS for the TB engine specified as 100,000
operating hours.
• Based upon empirical and operational experience, coupled
with the life extension work conducted on the SGT-200
(which evolved from the TB), Siemens are currently applying
150,000 hours maximum operation to the long-life (discs, shafts,
casings, etc.) components.
• In support of customer and business requests, Siemens have been
undertaking a specific program of work to understand whether
a further life extension can be supported.
• Upon completion, any further component life extension will be
communicated to our PCC workshop and regional representatives.

• There are over 450 TB units still in operation today
• Customers tell Siemens that they wish to run the TB for at least
the next 20 years
• The TB upgrades support the product lifetime extension, delivering improved
reliability and reduced product life cycle costs
• Adoption of the modern SGT proven designs provides alignment
of technology between current products and the mature fleet
It is Siemens intention to not only support the mature fleet for the foreseeable future, but
to continue to invest and further improve the product for the benefit of our customers.
